Definitions

the invention relates to a jump drive for medium-voltage switchgear in accordance with the preamble of claim 1.
jump movements for the switchgear are generated for drives for the switches and earthing devices via tension, compression or torsion springs using a wide variety of designs for the spring force-transmitting components.
a jump drive according to the preamble of claim 1 is already known (FR-A-0 286 474).
a compression spring ensures the switching movement of the switch and earthing device.
the compression spring has a fixed pivot point on one side and transmits its spring force as a jumping movement via complex cam, ratchet and freewheel controls, which are connected to a large number of levers.
the invention specified in claim 1 is based on the problem of reducing the number of complex control parts, increasing the functional reliability and designing and arranging the remaining parts in such a way that a small-sized and easy-to-assemble spring drive is produced.
the drive shafts in a double function unlock the drive locked in the "off" position and can set the associated switch in a switching movement.
a fixed stop on the respective drive shaft together with a push-lock bolt guided in the support frame of the drive, locks the movable switch and ground contacts, which advantageously prevents the movable switch and ground contacts from swinging and having a reaction on the switch spring.
the drive can be kept small by moving the freewheels from the actual drive to the actuating device.
the different design of the freewheel insert rollers of the actuating device ensures the unmistakable nature of a drive circuit.
a further embodiment of the invention is specified in claim 4. With a holder for a stop screw, a fixed stop connected to the drive shaft is prevented from swinging back during an "off" switching movement.
the drive shafts in the vicinity of the insertion openings for an actuating device are provided with half slots transverse to the respective axis of the drive shafts. This makes it possible to guide a locking plate which contains two cutouts which are arranged such that when a drive is switched "on", the insertion opening of the other drive shaft is closed.
all parts of the drive are a complete drive unit assembled in the U-shaped support frame, in which the two drive shafts are each mounted twice.
Such a drive unit can be attached to a switchgear assembly with little effort, only the switch shaft having to be coupled to the drive.
the spring drive has a drive shaft 1 for a cable switch and a drive shaft 1 ' for an earthing switch. Both drive shafts 1, 1 ' are arranged in bearings 22 (not shown) and 22' of a U-shaped support frame 21 at a distance parallel to one another. Because of the equality of the two drive shafts 1, 1 ' , the description is limited to the drive shaft 1 for the cable switch. In the drawing, all reference signs relating to the earthing switch are given the same reference sign as for the cable switch, but with an additional " ' " Mistake.
the drive shaft 1 is designed as a hollow shaft and has an insertion opening 2 with a driving contour for an actuating device 37 on the operating side .
the drive shaft 1 has a half slot 3 for guiding a locking plate 23 which can be moved parallel to the front of the support frame 21 is.
the locking plate 23 has two recesses 24 which are distributed in the locking plate 23 so that when a drive shaft 1 or 1 'is actuated, the other drive shaft 1 ' or 1 is closed.
a pair of spring levers 4 within the support frame 21 , which consists of two levers which are guided parallel to one another and are fastened to the drive shaft 1 .
the spring levers belonging to a pair of spring levers 4 are connected to one another by a spring suspension bolt 7 .
a lever 16 (FIG. 5) has the task of receiving an adjusting screw 17 (FIG. 5) for a push lock pin 18 .
This push lock pin 18 is arranged parallel and eccentrically to the drive shaft 1 and is guided in an elongated hole 28 in the support frame 21 .
a guide shaft 45 for the guide piece 13 and the push lock pin 18 serves to safely guide these two elements.
a compression spring 19 is limited on one side by a receptacle in the guide piece 13 and on the other side by a spring pressure holder 20 .
a drive pin 29 engages in the slot 10 of the driving lever 9 in the push rod, where it establishes the connection with a push rod 30 with freewheel.
the push rod 30 with a freewheel has an elongated hole in which a driving arm for a selector shaft 31 and the locking plate 23 engage.
the Switching shaft 31 is located in a pressure-resistant SF6 switch housing 33 and projects into the support frame 21 of the drive with a stub shaft.
the selector shaft 31 has driving arms for the push rods 30 and the locking plate 23 .
the control shaft 31 is guided through the housing wall with a sealing flange 34 . With the control shaft 31 three driving levers 35 are connected in the pressure-resistant SF6 switch housing 33 , which establish the connection to the movable contacts of the switches via insulating rods 36 .
a single actuating device 37 is provided for actuating the two drive shafts 1, 1 ' . It consists of a manual operating lever 38 , which contains a plug-in idler roller 42 with a small diameter and a large length and a plug-in idler roller 42 ' with a large diameter and a small length (not shown) in a rotary bearing 43 .
a removable crank for the manual operating lever 38 can be locked with the aid of a locking pin 39 .
a drive pin 44 is located between the insertable idler roller 42 and the rotary bearing 43 .
Markings 25 on the locking plate 23 indicate the respective position of the associated switch.
the actuating device 37 consists of a manual actuating lever 38 (shown in FIG. 1) with a two-armed pivoting lever, the arms of which are designed as plug-in idler rollers 42 and 42 ' .
the insert rollers 42 with a small diameter and a large length are designed for the drive shaft 1 and the insert rollers 42 ' with a large diameter and a small length for the drive shaft 1' .
Only one insertion roller 42 or 42 ' can be used at a time, the working position only releasing one insertion roller, while the other insertion roller is covered in the shaft of the actuating device 37 .
For the crank (only shown in FIG.
Driving pins are located between the insert rollers 42 and 42 ' 44 and 44 ' .
a roller locking pin 5 ' in the drive shaft 1' prevents the insertion of the longer and smaller diameter roller 42 .
the guide piece 13 has a recess 14 for receiving the push rod 12 and a recess 15 for receiving the compression spring 19th
a lever 16 connected to the guide piece 13 serves to receive the push lock bolt 18 , which is connected to the lever by means of a screw 17 .
6 and 7 show the push lock pin 18 in two views.
