Since the purpose of the device described above is to activate or deactivate the contactor device with automatic opening in case of a fault or optional opening by external manual means via a local control member, the control switch 50 is The contactor is provided in series with the coil of the electromagnet 51 of the contactor, which is shown schematically at 54, and further includes a fixed contact 52 supported by the case, for example, and a movable contact 53 interlocked with the fixed contact 52, in the illustrated example. , the movable contact is supported by a fixed lever 10,
The switch 50 is closed when the transmission member 3 is in the closed position F and the fixed lever is in the rest position relative to the stop. The slider 43 or 47 is moved abruptly in the E or H direction by a resettable overload detection device or member provided in the case and indicated schematically by 55, 55', 56, 56' and 57, 57'. and the load circuit 5 of the contactor 54
8 in response to various levels of overcurrent. Reference numerals 55', 56' and 57' indicate a striker, a magnetic plate and a bimetallic piece, respectively.

The operation of the device described above is as follows.

When the tripping claw 29 is moved in the S direction by either the slider 43 or 47 due to sudden movement in the E or H direction, the tripping lever 20
The teeth 26 of are released, the tripping lever 20 rotates in the M direction, and during the rapid movement due to the release of the spring 27,
The stud 24 abuts an abutment surface, for example the abutment surface 8, and brings the trip lever 20 into an operating position in which the stud 23 is at level 7 and faces the abutment surface 6;
As a result of the movement of the torque _C4 , the nose 19 is struck by the hammer 22, and as a result, the fixed lever 10 rapidly rotates in the Q direction.
and the end 18 of the bolt 15.

The transmission member 3 released in this way moves in the L direction until its contact surface contacts the stud 23.
The transmission member 3 then enters a stable so-called tripping position D in which the switch 50 is open, and is opened in this way because when the fixed lever 10 suddenly moves to the operating position and leaves the stop 12, the bolt 15,
This is because the end of 5' contacts the edge 5.

In this position, the stud 25 touches the face 49 of the reset lever 35 and moves it so that the end face 39 is close to the abutment face 9 of the transmission member 3.

The action applied to the transmission member 3 in the K direction to operate the device, that is, to bring it into the closed position F, is exerted by the tripping pawl 2.
9, the fixed lever 10 is not allowed to reach its rest position, the switch 50 is closed, and the end 1 of the bolt 15 is closed.
8 is brought into contact with the contact surface 6.

On the other hand, the device optionally includes member 2 in the L direction.
permanently open position O through an external action applied to
First, the tripping lever 20 is rotated in the N direction in order to cause the abutting surface 6 to act on the stud 23. This rotation causes the stud 23 to move away from the abutment surface 6 and into contact with the surface 5. This rotation allows the contact surface 9 to cooperate with the end surface 39 of the arm 38 of the reset lever 35 to obtain a stable open position O. This open position O is applied by springs 27, 4 and on the one hand spring 27, trip lever 20, stud 25, surface 49, reset lever 35, arm 3.
8. This is due to the balance of contradictory forces transmitted by the end face 39 on the one hand and the spring 4, the transmission member 3, the abutment surface 9, etc. on the other hand.

After automatic tripping, resetting the tripping device of the device will, on the one hand, bring the transmission member into the closed position F, and on the other hand, change the position of the detection devices 55, 56, 57 and the sliders 43, 47 to the obstruction position. This will result in a state where there is no The sliders 43 and 47 are moved in the G and J directions, respectively, and the passages 59, 60 and 6 are
This reset, transmitted by one means, is obtained by the cooperation of the abutment surface 9 (or the edge 62 separating this surface from the abutment surface 8) of the reset lever 35 against the end surface 39.

This reset is carried out from the tripping position D or the open position O to the reset position R by the external action of the member 2.
, during the controlled movement of the transmission member 3 in the L direction, the abutment surface 9 pushes back the lever arm 38 while pushing the reset lever 35 until the nose of the tripping pawl 29 slides behind the teeth 26. The tripping lever 20 is rotated in the N direction, and the sliders 43 and 47 are moved in the G and J directions by the ends 41 and 45 of the arms 36 and 37, respectively.
drive in the direction. The reset position R obtained in this way is not stable due to contradictory elastic actions transmitted from the spring 27 to the transmission member 3 by the tripping lever 20 and the reset lever 35.
When the external action is removed, the transmission member 3 is in the open position O.
Return to

In the embodiment shown in FIG. 2, parts having the same functions as those in the previous embodiment are denoted by the same reference numerals.
The two pivots 21, 21' have axes that coincide at 21, and the abutment surfaces 6', 9' are adjacent surface parts belonging to the same plane. The device shown is in the closed position F.

Case 1 is shown here so that surface 24' can be easily seen in the drawing.
The release lever 20', which cooperates with the upper stop 8', is also in the operating position by resting against the abutment surface 8'', similar to the abutment surface 8 of FIG.

In the actuated position of the tripping lever 20', the flange 23' of this lever coincides with the abutment surface 6' or the edge 62' separating it from the surface 5 to maintain a stable tripping position D of the transmission member 3. , and the local control member 2 connected thereto (see FIG. 3a).

The rotating fixed lever 10 (see FIG. 2) has a contact lever 63 which is brought into rest position by a spring 65 against a stop 64 of the lever.
The end 66 of this contact lever raises the movable contact 53' and separates it from the fixed contact 52', which belongs to a control switch 50' which has the same function as the control switch 50 described above.

Regardless of whether the fixed lever 10 rotates or not,
When the end 66 is pushed back in the K direction by the action T, the switch is released by the tripping lever and then by the fixed lever 10 pivoting in the Q direction.

The switch 50' suddenly opens due to the momentary rotation transmitted to the fixed lever 10 by the tripping lever, or when the transmission member 3' is moved to the open position O by the local control member 2, the bolt 1
This is because 5, 18 and the contact surface 6' are instantaneously separated.

In the first case, in opposition to the torque C ₁ in the P direction transmitted by the spring 13, a reciprocal torque is transmitted by the spring 27 to the fixed lever 10 in the M direction.

In the second case, member 2 and transmission member 3'
The external force transmitted to is added to the force of the return spring 4 and first rotates the retractable bolt 15 in the Q direction against the torque C ₂ given by the spring 17;
Torque C ₃ larger than torque C ₁ is fixed lever 1
0, the retractable bolt is in an inclined position with respect to the abutment surface 6', so that the fixed lever 10
pivots very rapidly in the Q direction, causing the bolt 18 to slide along the edge 62' and rest against the abutment surface 5, holding the switch 50' open.

As in the case of FIG. 1, in the tripping position D and the opening position O, there is reciprocal cooperation between the contact surfaces 6', 23', the contact surface 9', and the end surface 39', and the transmission member and local The control member is placed in two stable positions. In Figures 3a and 3b, opposite arrows indicate this cooperation.

Moreover, the unstable position R is obtained by the return force to the open position O transmitted to the transmission member 3 by the spring 27, and the action of this spring is caused by the release lever 20', its arm 25', the surface 49, the reset lever 35 ' and end face 39', end face 39' is transmitted by face 49'
It is acting on In Figure 3c, opposite arrows indicate reciprocal effects.

In the two illustrated embodiments, the movement of the transmission members is linear and the device comprises these transmission members 3,
3' is the axis perpendicular to the tangential movements K and L, for example.
When it is a rotating part integral with the rotary knob 2 that moves around YY', it is adapted to operate in the same manner.

In the embodiment shown in tripping position D in FIG. 4a, the same reference numerals designate the same functions,
The rotary transmission member 3'', which performs the same function as , can rotate around a pivot 68 whose axis is parallel to the axes of the parallel pivots 11, 67, 14, 21, 30.

The contact lever 63 has a first end 66', the function of which will be described below, and a second insulated end 69, which, like said end 66, cooperates with the movable contact 53'.

For configuration reasons, the reset lever 3 is shown in dashed line.
In place of the arm 41 and end 45, 5' is a stud 41' which has the same function as the arm 41 and end 45 by cooperating with the end 42 and end surface 46 for resetting.
It has an end 45'.

The contact surfaces 6' and 9' shown in FIG. 6 are straight lines, but are stepped in the axial direction along the rotating rotary transmission member 3'', and this transmission member has a cylindrical surface that serves as a stop for the surface 24. 8. The protrusion 87 (FIG. 4) of the rotational transmission member 3'' prevents the arm 38 from contacting the rotational transmission member 3'' at a position other than the contact surface 9'.The tripping lever 20'' has an arm 25' which cooperates with the stud 49' of the reset lever, the function of which is the same as that of the surface 49. The nature and mode of operation of the variant is substantially the same as the device of FIG.

A tripping mechanism such as that shown in FIGS. 2 to 6 is particularly well suited for remote control by being subject to an external control action. These actions are provided by an electric actuator using, for example, a small synchronous motor to remotely reset and activate the device to close it. The mechanism between the reset, tripping and closing functions of the control switch, the configuration of the moving direction of the parts that perform these functions, and the closing position F, tripping position D, opening position O, and reset position R
Due to the disconnection afforded by the intervening configuration, remote control of devices with this mechanism is easily achieved, with remote reset after automatic opening.

In fact, in the functions shown in FIGS. 2, 3, 4, and 6, the transmission member is moved in the K direction to bring it to the closed position F, and the reset lever is operated during reset. As the arm 36 moves, the contact lever 6 is moved to hold the switch open.
3 to end 66' are parallel and in the same direction.

Therefore, for example, a third
three parts 71 adapted to apply thrust in the same direction (indicated by arrows S, T, V) to the third abutment surface 74, end 66' and arm 36 of transmission member 3' located at level 75; 72, 73 for interlocking these three mechanisms (see FIG. 5, neither the trip lever nor the trip pawl are shown for clarity in the drawing). be able to.

A third slider 7 that interlocks the return spring 77 and the stopper 76 of the case so as to fix the rest position.
0 is indicated by the position Z that the transmission member 3' occupies when it is captured by the bolts 15, 18 and held in the closed position F.

A subassembly 78 is removably fixed to the case 1 and has two supply terminals 79 and 80 to which a small synchronous one-way motor 81 is connected, for example, and a holding switch 82. It has a pusher 83 and a cam 90 which are operated by a motor via a cam 90. This pusher 83 has an opening 88
and after passing through the opening 89 of the case 1 , it cooperates with the thrust surface 87 of the third slider 70 .

A short-term start is supplied directly to the motor via a switch 91 between the terminal 77 and the third terminal 84 by a switch 82 that opens only when the pusher 83 is in the rest position W and closes as soon as it moves in the K direction. Ensure continuity of supply to the motor when voltage is lost. This voltage is applied when a remote reset is performed.

In conjunction with the spring 86, it moves in the K direction only once at a time, and further moves to successive positions W, B, X, B,
The pusher 83 extending between W and returning in the L direction has an amplitude
It communicates with the movement of the third slider 70 of WX.

The rest position W of the slider corresponding to the rest position of the third slider 70 is such that the abutment surface 74 is in contact with the portion 71 even in the reset position R given to the transmission member 3' by a manual external action applied to the local control member 2. It has become impossible to do so. Similarly, neither the arm 36 nor the end 66 can abut the parts 73, 72, respectively, in the tripping position D of the transmission member.

The highest position X reached by the slider and applied to the transmission member 3' is such that the abutment surface 6' is slightly to the left of the bolt 8 and is positioned by the action of the spring 13.

In all positions of the third slider 70 located to the left of position B, the portion 72 mates with the end 66' of the contact lever and holds the switch 50'open;
During the movement from W to Fifth
The position shown is reached and switch 50 closes only when the slider returns to position B to the right. However, the detection device 57 (which itself is
If the slider 47 is not moved in the H direction by the bimetallic piece 57' (responsive to the high temperature bimetal piece 57'), the tripping lever 20', which would actually be reset, is only held by the tripping pawl 29, so the slider 47 is not in the position toward J, the tripping lever 20' rotates the fixed lever 10 again before reaching point B.

The effects obtained during remote control of the device described above can be compared to the effects obtained by manual reset and closing actions applied to the local control member.

In the embodiment shown in FIG. 4b using a transmission member 3' as shown in FIG. 6, abutment surfaces 74' having the same function as the surfaces in FIG.
The contact surfaces 6' and 9' are aligned in a straight line while being stepped in the axial direction so as not to interfere with the contact surfaces 6' and 9' (see FIG. 6).

When the reset is performed, the end portion 66' and the abutment surfaces 74', 41', which are all located below the axis 68', move in the same direction K. A slider 70 is advantageously used (FIG. 4b shows the parts in a state comparable to that of FIG. 5).

During these various reset procedures, engagement of the tripping pawl behind the tooth is only possible if the condition or obstruction that caused the tripping in the tripping position D has been eliminated. Since the contactor is open, and as a result there is no current flowing in the load circuit, the only situation that will prevent the trip pawl from engaging is if the bimetallic piece 57' is still hot following a prolonged overload. This situation is due to the bias of In this situation, due to the overload detector 57 and the effect permanently transmitted during cooling of the bimetallic piece across the passage 61,
Do not let the slider 47 move to the J position,
By thus preventing the tripping pawl from reaching its rest position, when the transmission member leaves the reset position R and moves towards the next opening position O and closing position F, the pulling lever 20, 20', 20'' does not reach its set position.Due to this impossibility, the fixed lever 10 does not reach its rest position, so that even when the transmission member 3 is returned to the closed position F, the switch 50 remains open; Therefore, as long as the bimetallic piece is still hot, the load circuit cannot be reset.

If the failure to open the contactor and thus the positioning of the transmission member in the open position O occurs instantaneously (without giving time for the bimetallic piece to heat up) due to a complete short-circuit or a disturbed short-circuit, then from the trip position D to the reset position movement causes the trip lever 20' or 20'' to be in the set position, since no permanent action from the magnetic or thermal detector is transmitted to the passage 59 or 60 corresponding to the slider 43 or 47, respectively.

If an attempt is made to put the device into operation by moving the transmission member from the reset position R to the closed position F, the result is that, when this member reaches position F, it rotates the fixed lever 10, but it does not move the trip lever 20. This is because the hammer 22 has moved away from the nose 19. In addition, if it is in a short circuit state, the contactor 5
By closing the control switch 50 or 50' that energizes at least one of the detection members 55 or 56, the tripping levers 20, 20', 20'' and the fixed lever 10 are continuously pulled. Since the switch 50 or 50' is removed and the switch 50 or 50' is opened again, the load circuit is again opened by demagnetizing the electromagnet 51.

This operation takes place whether or not the transmission members 3, 3' are held in the closed position F by external manual action.
