Description

[Detailed description of the invention] This invention relates to a drive device. Specifically, the present invention is as follows.

The present invention relates to an electrical device used in a low-voltage supply distribution network, including fuses and/or switches, and a drive device used therein.

When supplying and distributing low-voltage current from indoor and outdoor substations, the supply and distribution network incorporates equipment such as fuse panels to suit the surrounding environment.

Traditionally, four or five supply buses are used, three of which are used for each phase of the three-phase current, and the remaining one or two buses are used for common It is used as both a neutral wire and a ground wire, or as a neutral wire and a ground wire, respectively.

The three-phase current output from the power source is connected to the power transmission cable connected to each line via a fuse for each phase. These three fuses are
It is housed in one power distribution device, and has a contact point connected to each line, and is placed separately from the contact point, which is connected to each line.
It engages with other contacts connected to each output and bridges the contacts.

In the case of power distribution devices of the above-mentioned type manufactured according to the standards of d), each contact is completely exposed when the fuse is not fitted.

To bridge the contacts, the fuse is engaged by one end with one contact, pivoted about its retaining portion, and manually moved to connect with the other contact. In this case, it is also possible to add a fixed or removable fuse holder to the fuse and operate it by hand.

To safely install the fuse while the busbar is energized,
Speed and reliability of work are required.

This is especially true if the output line is out of order because strong arcs are likely to occur and the work becomes dangerous.

Furthermore, when removing a fuse from a energized circuit, a similarly reliable operation is required and the work is similarly dangerous.

In addition to these operational hazards, if the fuse is removed, the live and energized contacts will be exposed, making this type of power distribution equipment is extremely dangerous.

In the case of other power distribution equipment of the same type, when the fuse is not installed, the contacts are covered, and when the fuse is inserted or removed, the worker is protected from direct exposure to the arc. Protective means and means for reducing the likelihood of arcing are provided.

However, even in the case of this device, the insertion and removal of the fuses is done manually, so there is a potential danger, and in order to work safely, speed and reliability are still important. required.

In the case of further types of distribution equipment, each fuse may be permanently fixed and may be inserted and removed using a controllable device for the necessary operation. can.

In this case, operational safety is improved, but the equipment becomes expensive.

It is an object of the present invention to provide a device which improves the safety and economic efficiency of the power distribution device as described above, and which can also be applied to other electrical equipment regarding the operation of fuses and/or switches. It is in.

The electrical device according to the invention has an opening leading into its interior;
a fixed casing comprising a pair of fixed contacts spaced apart from each other at a position recessed inward from the opening; a member forming a contact carrier carrying a pair of movable contacts; and the casing. and contact carriers,
and a first position within the casing where the movable contact and the fixed contact are separated and released, and a second position within the casing where they are engaged and connected to form a closed circuit. the contact carrier comprises a guide device for moving the contact carrier along a straight path, and a drive member moving relative to the housing, and mechanically driving the contact carrier between the two positions. a self-contained drive for
It consists of a coupling device for detachably coupling the drive member to the contact carrier, and a fixing device for detachably fixing the housing to the casing.

In such a device, the fixed contact is placed at a position inside the casing rearward from the opening.
Since they are well protected, the possibility of coming into contact with them during work is substantially reduced.

Furthermore, by making the contact carrier of the moving contact mechanically drivable, it is possible to operate the contact carrier from a sufficiently distant position without having to approach the fixed contact. in this way.

The device according to the invention has a much safer construction than conventional devices.

By using a removable and self-contained drive,
Furthermore, it is advantageous in terms of cost and safety. Suwachi,
Since a single drive can be used to move five contact carriers in sequence, there is no need to provide a separate dedicated drive for each contact carrier. Furthermore, when the drive device is not in use, it can be removed and safely stored to prevent accidental operation.

Conveniently, the guide device comprises a slideway on the inner wall surface of the casing extending from the opening toward the fixed contact, and sliding means attached to the contact carrier and engaged with the slideway. Good.

The contact carrier can be used as a switch with only contacts connected directly to each other in order to bridge fixed contacts. In this case, one of the fixed contacts in pairs serves as an input contact, and the other serves as an output contact, and the output contact can be connected to an output line via a fuse.

Furthermore, between the output end of the fuse and the output line,
connected via another contact mounted on another contact carrier,
It is also possible to form a circuit that can be opened and closed on both sides of the fuse.

In yet another embodiment, a cartridge type fuse for electrically connecting pairs of moving contacts can be mounted on a contact carrier to achieve a wider range of applications.

When an electrical device according to the invention is fitted with a deworming device and released, the contact carrier may move between the first and second positions. In this case, if the drive device is properly positioned, the deworming device will cause the deworming device to release. This means that the contact carrier can only be moved if the drive device is used properly. Good.

Furthermore, a separate deworming device may be provided, so that the drive device can only be operated when the electrical device is located in the correct position.

The present invention includes a self-contained drive device that can be used in combination with the electrical devices described above. This single drive device can also drive the driven member in the direction of the chair between two fixed positions by connecting the driven member.

This drive device includes a housing, a drive member that starts from any rest position with respect to the housing and stops at another rest position adjacent to the housing, and connects the drive member in the rest position to the driven member. a coupling device that operates between the housing and the drive member to move the drive member from each rest position to the immediately next adjacent rest position even if the drive member is moved in the forward or reverse direction; It consists of a drive unit that can

Regarding the electrical device according to the invention described above, the component that is removably connected to the drive device is the contact carrier.

Inside the casing, there are three
It is customary to accommodate pairs of fixed contacts.

Connected to each pair of fixed contacts is a moving contact carrier, usually used as a fuse carrier. In this case, a self-contained drive is used to move each moving contact carrier in turn from a first position to a second position, or vice versa.

Fuse panels and the like are usually installed in large equipment called banks, and it is sufficient if one drive device is provided for each bank.

The driving device is connected to a wander lead wire.
By grounding using ad), safety can be further improved and the drive device can be prevented from being inadvertently removed from the electrical device.

Hereinafter, the present invention will be described in detail through examples thereof with reference to the accompanying drawings.

Figures 1 to 3 show a three-phase output device for use on a fuse panel or similar device having three different busbars (1) to (3) for each phase of the power supply. There are n.

This three-phase output device is equipped with a casing (4) in which two plastic molded casing members (51 (61) of similar shape are integrated by an appropriate means. Each casing member +51 (61 has a , the wall portion (8) (9

Three pairs of fixed contacts are mounted within the casing. The first input contact (111) and the output contact (12
is arranged in the lower part of the casing (4) and connected to the n-5 first bus bar (1), and the second input contact (13) and output contact (14) are arranged in the middle part of the casing (4). connected to the second busbar (2), and similarly to the third busbar (2).
The input and output contacts of are arranged in the upper part of the casing (4) and connected to the third bus bar (3).

These three input contacts are all the same,
For example, the input contact (11) consists of a temporary contact (19) that grips the bus bar (1) and a fixed contact (I6). Contact 01) is connected to the leaf spring 07! (By 110, the opposing parts are brought together and fixed as one body.

- Each output contact has the same structure. For example, output contact 02 consists of a contact sleeve and a fixed contact (20), and the opposing parts are brought together by a leaf spring to form a single body. It is fixed to j,.

The fixed contact (201) is equipped with an arc extinguisher (23). The contact a is connected to the first output conductor (24) f.

Each contact of the other two output contacts is connected to the second and third output conductors Q51 (2e).

The output device described above is designed to be sufficiently safe when used in addition to a fuse panel or similar device.

Two fixed contacts (16

), and the two casing members (5) and (6) are sufficiently protected by a protection plate (27108+) formed integrally with the two casing members (5) and (6). Therefore, it is impossible to accidentally touch each contact point during use.

In order to connect the power supply side busbars (1) to (3) to the output conductors (24) to (20), bridge the fixed contacts (16) for each phase with a fuse. This is a common practice.

In FIG. 1, a fuse in an open state is shown in the lower part, and another fuse in a closed state is shown in the middle part. ing.

The middle part of Figure 2 shows the fuse in a closed state, and the lower part shows the state with the fuse removed.

By providing the sliding portion and the slideway in this way, each fuse carrier has 0! Since j can move on a straight line, the moving contact (to) CIl attached to the
It is possible to accurately couple and release the fixed contact o61 (a) with the fixed contact o61 (a).

The upper part of Figures 1 and 2, and the t shown in Figures 3 and 4.
A self-contained drive means that each fuse carrier can be moved between open and closed positions.

The drive device has a housing 60), inside which is a cylindrical shaft in which four cam grooves 6 are formed.
)-C11) is rotatably mounted.

Each cam groove 6z is bored on the outer peripheral surface of the sleeve 61) in a range slightly exceeding 90 degrees.

Each cam groove has an operational starting point 53) and an operational ending point 64) located 90 degrees apart from the cam groove, and each starting point 63) is located at the center of rotation of the sleeve 61). and each end point l54)
is tilted so as to be located on a second plane parallel to the first plane.

Further, each starting point l53) and the end point 64) of the cam groove adjacent thereto are located on a common plane including the rotation center axis.

A coil spring device is provided in the case 6 and is controlled by an operating member (a) that drives the device via a rod shaft 6η having a rectangular cross section.

Spring devices of this type are well known in the art and are manufactured by IMI Sandton Limited, Somerton Works, Newport, Quentt, UK.

T-H%], those supplied in J are preferable.

In this spring device, when the operating member 66) is rotated in either direction, a force can be applied to either of the two coil springs, and when that reaches its limit point,
The stop device automatically releases the sleeve 61) so that it rotates in the same direction as the operating member.

Furthermore, this spring device allows the five operating members to be adjusted even if they are rotated in any direction, so that the sleeve 61) can be driven in an appropriate direction. In this way, the spring device, when operated continuously,
- No need to readjust each time.

In order to drive the fuse carrier C19), it is necessary to properly attach the drive device to the electrical device. This proper joining position is shown in the upper part of FIG. 1, FIGS. 3 and 4.

As shown in the figures, both sides of the housing 60) have grooves, grooves, and grooves on the upper and lower parts of the housing 60).
(59+ are provided, each with a dowel (60)
) (6]). The dowel at the bottom of each phase hits the dowel at the top of the phase immediately below it.

When all the grooves are fully engaged with their respective dowels, the pins (371 (38)) engage the start or end points of the two cam grooves 62 on the mutually symmetrical sleeve 61. In this way, by engaging the pin t3nC3a with the cam groove 62, the sleeve 51) is removably connected to the contact carrier (a), and the groove 610 is engaged with the dowel 11). By doing so, the housing 60) of the drive device can be removably fastened to the casing (4).

A deworming device is provided to prevent the fuse carrier (20) from unintentionally moving between the first and second positions when the drive device is not installed.1. ing.

On both sides of the casing (4), there are guide passages (6) for each phase.
21 is provided along which a stopper member (6 (
6) can slide vertically. Each stop member (63) is normally in the uppermost position by a compression spring (64). The stopper member is adapted to align with the recess (66) on the side of the protrusion (5 fuse carrier C29 having six) or the protrusion 6'71 above it.

As shown in the center of Figure 1, fuse carrier Q9)
can move freely between the open position and the closed position when the protrusions (6) are aligned with the recess $61, but the protrusions (
67), it cannot be moved due to the stopper member (goods).

The stopper member (goods) is attached to both walls (8) of the casing (4).
It is provided with a cross-shaped member (681) on a plane parallel to (91), one end of which is adapted to be received in the groove (6 wings) on the housing 60 of the drive device.

As shown in FIG. 1, when the drive device is installed correctly, the stopper member is in a lower position than usual, so that the protrusion and the recess 6 [i] are aligned. , the fuse carrier (2g1 can move freely; the drive device is
When removed by lifting it upward and then pulling it outward to release the engagement with the dowels (60) and (61), the locking member [F]■ is released by the action of the compression spring (64). , since it returns to its original upper position, the protrusion (6ω) and the protrusion (67) align to prevent the fuse carrier blade from moving.

The drive device also includes a separate deworming device to prevent operation if it is not properly attached to the electrical device.

On both sides of the housing I5, free-stop arm surfaces are pivoted about a shaft 61) located below the rotation center axis of the sleeve 61).

Both arms ff0 have their upper ends ff2 connected to the housing 6
It is fixed by manually engaging the upper end ff41 of the plate member σ (support) through the opening σ powder provided at the top of the plate member σ. A keyhole ση is bored in the downward extension ff6) which is the other end of the plate member σ.

Due to this positional relationship, the shoulder of the arm 60) is adjacent to the upper dowel (60), and the first drive device is connected to the dowel (60).
tl) (This is a preventative measure to prevent you from leaving 61+ carelessly.

To remove the drive device, grasp the upper end ff4) and pull the plate member σ3) and the arm (70) in the direction of the operating member 66).

At this time, since the rod shaft 651 enters the rectangular portion of the keyhole surface, rotation of the shaft is prevented and it is difficult to operate the drive device.

By moving the plate member σJ and the arm σ0 simultaneously and in parallel, the drive device can be installed in the casing (4).

The operation for inserting a fuse into the lowest phase of the circuit in FIG. 1 will be described below.

First, when the fuse carrier (29) is manually placed in a predetermined position, the sliding portion C31 and the slideway (40) engage.

The anthelmintic member (63) makes it impossible to move the fuse carrier (29) any further in the direction of the fixed contact Qfil (20).

Next, the drive device is used to move the stop arm (70) as described above and insert the groove (Jei-bo) into the dowel (60) (611
and lower the device at the top of FIG. 1 and at the predetermined position dimensions shown in FIG.
Attach it to the casing (4) so that it is suspended from all.

Due to the stiffness, the protrusion (6) of the deworming device (63) aligns with the opening (611G), so the fuse carrier can be moved.The housing 60 of the drive device
) in the correct position with respect to each dowel f60) (611), at the same time the cam groove 62 is automatically and precisely positioned with respect to the pins 07!038+, making it the symmetrical of the four Starting point of two cam grooves 53)
At , it engages with pin 0η (to).

Next, by operating the operating member 66) to apply force to the coil spring and release the force, the sleeve 6
When 1) is driven clockwise in Fig. 2, the rotational motion is converted into linear motion by the action of the cam mechanism and is transmitted to the fuse carrier (2 (support)). (a) Connect the upper contact (to) 01) to the fixed contact (
It can be electrically connected to 161 examples.

When the stop arm σ0) is released, the drive device can be easily lifted and removed from the predetermined position, but at the same time the deworming member (63) is activated and the fuse carrier e (g) cannot be pulled out. It disappears.

In this way, contact (30) 0 on the fuse carrier
1) and the fixed contact 161 (2n) can be operated at a sufficient distance from the area to which they are actually connected, so that they are sufficiently protected from the effects of arcing.

Also, the housing 6Q can be suitably shaped so that the products of the arc are evacuated from the sides and rear of the housing (50) rather than from the front, providing even more protection.

Furthermore, the mechanical action of the spring and the reliable fuse guiding mechanism ensure that the electrical connection of the fuse is made quickly and reliably, thereby mitigating the effects of any failure. I can do it.

When removing the attached fuse carrier wing, simply repeat the same operation, but in this case, connect the end points of the two symmetrical cam grooves to pin C371 (
) and by rotating the sleeve f5]) counterclockwise, the fuse carrier can be released.

Operational safety is increased by the deworming device f17.

If for some reason the fuse carrier 09) is not fully connected or disconnected when the operating member (56) is operated, the cross-shaped member (681) of the deworming member (63) ": Lift the drive unit from its installed position.

It cannot be removed by force. In this way, if there is an abnormality, it will be obvious.

Due to the shape of the cam groove 6 and the mechanism that can reliably drive the sleeve (!] 1) 90 degrees in one operation, the fuse carrier can be moved in either the open or closed position. , the sleeve 61) can always properly engage the pin 071 (to). Chair n,
Even in the direction of , there is no need to readjust the drive device each time when performing continuous drive operations.

For this purpose, the number of cam grooves does not necessarily need to be four. That is, regardless of the number of cam grooves, all their starting points are located on one common radial plane -4-, all their ending points are located on another common radial plane, and each When the starting point of a cam groove and the end point of an adjacent cam groove are located on a common axial plane, and the number of cam grooves is n, the number of sleeves that rotate in one operation is The rotation angle should be n/360 degrees.

Even for a large installation consisting of a large number of devices each having three-phase output lines, only one drive device is sufficient.

The frame holding the busbar is usually grounded, and the drive device can be grounded with a wander lead wire of sufficient length, so that it can be placed in any position. Even if there is, it can be engaged with the carrier.

The use of a wander lead not only improves grounding safety, but also prevents the drive from being accidentally removed from the equipment.
