Abstract
The utility model provides an interlocking device used for a high-voltage switch cabinet and belongs to the technical field of high-voltage electric equipment. The interlocking device includes a secondary socket frame. A side of the secondary socket frame is equipped with a secondary plug and a secondary socket. A protection board is arranged outside the secondary plug and the secondary socket. The protection board is connected with a rotary shaft installed in the secondary socket frame. The rotary shaft is also equipped with a pushing device pushing the rotary shaft to rotate, so that the opening and closing of the protection board is realized. When a circuit breaker is proceeding from a test position to a working position, a circuit breaker face board pushes the pushing device, the pushing device pushes the rotary shaft to rotate, and then the rotary shaft drives the protection board to rotate, so that an aim of locking the secondary plug and the secondary socket is realized.
Description
Technical field
The utility model belongs to the high-voltage electrical equipment technical field, relates in particular to a kind of interlock of high-tension switch cabinet.
Background technology
The guard signal of switch cubicle is to be transferred to circuit breaker by secondary plug and Secondary socket, reaches the control purpose.Secondary plug and Secondary socket are linked together by the grafting form.
In prior art, at switch cubicle, when working, without " mistake is pulled out " of preventing secondary plug and Secondary socket, install.
The utility model content
For above-mentioned defect or deficiency, the utility model provides a kind of interlock of high-tension switch cabinet simple in structure.
For reaching above purpose, the technical solution of the utility model is:
Comprise the Secondary socket framework, one side of Secondary socket framework is equipped with secondary plug and Secondary socket, secondary plug and secondary arranged outside have backplate, and backplate is connected with the rotating shaft in being installed on the Secondary socket framework, also are equipped with in rotating shaft and promote the thrust unit that rotating shaft is rotated.
Pull bar and supporting seat, one end of pull bar is equipped with pressing plate, the other end stretch in the Secondary socket framework be installed on the Secondary socket framework in an end of supporting seat be connected, the other end of supporting seat is connected with first connecting rod, first connecting rod is connected with rotating shaft by second connecting rod, extension spring is installed on second connecting rod, and the other end of extension spring is fixedly installed on the Secondary socket framework.
Between described supporting seat and first connecting rod, first connecting rod and second connecting rod, all by bearing pin, be connected.
Described thrust unit comprises: backplate is the L-type structure.
Compared with prior art, the beneficial effects of the utility model are:
The utility model provides a kind of interlock of high-tension switch cabinet, by outside secondary plug and Secondary socket, adding backplate, and by being installed on rotating shaft and the thrust unit in the Secondary socket framework, realized the folding to backplate, in the traveling process that circuit breaker shakes " service position " by " test position ", circuit breaker panel promotes thrust unit, thrust unit promotes rotating shaft and rotates, rotating shaft drives backplate again and rotates, thereby reach the purpose of locking secondary plug or socket, in addition, because the utility model passes through part seldom, just can realize requirement, therefore, the utility model is simple in structure, reliability is strong.
The accompanying drawing explanation
Fig. 1 is the structural representation of the interlock of the utility model high-tension switch cabinet;
In figure, 1-1 is secondary plug, and 1-2 is Secondary socket, and 2 is the Secondary socket framework, and 3 is extension spring, and 4 is rotating shaft, and 5-1 is first connecting rod, and 5-2 is second connecting rod, and 6 is supporting seat, and 7 is pull bar, and 8 is pressing plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Shown in Figure 1, the utility model provides a kind of interlock of high-tension switch cabinet, comprise Secondary socket framework 2, one side of Secondary socket framework 2 is equipped with secondary plug 1-1 and Secondary socket 1-2, secondary plug 1-1 arranged outside has the backplate of L-type, the backplate of L-type is connected with the rotating shaft 4 in being installed on Secondary socket framework 2, also is equipped with in rotating shaft 4 and promotes the thrust unit that rotating shaft 4 is rotated.Concrete, described thrust unit comprises: pull bar 7 and supporting seat 6, one end of pull bar 7 is equipped with pressing plate 8, the other end stretch in Secondary socket framework 2 be installed on Secondary socket framework 2 in an end of supporting seat 6 be connected, the other end of supporting seat 6 is connected with first connecting rod 5-1, first connecting rod 5-1 is connected with rotating shaft 4 by second connecting rod 5-2, extension spring 3 is installed on second connecting rod 5-2, the other end of extension spring 3 is fixedly installed on Secondary socket framework 2, wherein, described supporting seat 6 and first connecting rod 5-1, between first connecting rod 5-1 and second connecting rod 5-2, all by bearing pin, be connected.
The course of work of the present utility model is:
Circuit breaker is shaken in Secondary socket framework 2, and circuit breaker shakes the process of " service position " from " test position ", and circuit breaker panel promotes pressing plate 8; Pressing plate 8 linkage pull rods 7; Pull bar 7 is under the orientation of Secondary socket framework 2 and supporting seat 6, along circuit breaker direction of motion interlock first connecting rod 5-1; First connecting rod 5-1 pulls and drives second connecting rod 5-2, and second connecting rod 5-2 promotes rotating shaft 4 and rotates; Secondary plug 1-1 is pinned in rotating shaft 4.
Otherwise, in the process that circuit breaker shakes " test position " by " service position ", pressing plate 8 loses the compression stress of circuit breaker panel, pull bar 7, first and second connecting rod 5-1,5-2 lose interlock power, due to the effect of extension spring 3, rotating shaft 4 returns to initial position, and secondary plug 1-1 can extract.
Can realize the following interlock requirement of switch cubicle by this device, that is: circuit breaker, can't " mistake is pulled out " secondary plug 1-1 when service position.
