Abstract
The invention discloses a breaker interlocking device. The bottom of an interlocking support I and the bottom of an interlocking support II are fixed to the left end and the right end of a breaker support respectively. One end of an operation rod penetrates through the circle center of an interlocking disc I and a locating hole of the interlocking support I in sequence. The operation rod is fixedly connected with the interlocking disc I. A shaft pin is fixed to the interlocking support II and penetrates through the circle center of an interlocking disc II. An interlocking connection block I is connected with the interlocking disc I through a fixing pin; an interlocking connection block II is connected with the interlocking disc II through a fixing pin; an interlocking connection block III is connected with the interlocking disc II through a fixing pin. The left end of an interlocking rod is in threaded connection with the interlocking connection block I; the right end of the interlocking rod is in threaded connection with the interlocking connection block II; the upper end of a breaker connection rod is in threaded connection with the interlocking connection block III. According to the breaker interlocking device, mechanical interlocking between a breaker and a mechanical latch becomes possible, and interlocking reliability between the breaker and the mechanical latch and the safety of a switch cabinet under this situation can be improved greatly.
Description
Technical field
The present invention relates to a kind of circuit breaker interlocking device.
Background technology
When unconventional circuit breaker joined by fixing cabinet, between mechanical latching and circuit-breaker switching on-off, mechanical interlocking realizes difficulty, and existing is all realized by electrical interlock, and electrical interlock has instability, not directly perceived, unreliable ground shortcoming compared with mechanical interlocking.
Summary of the invention
For solving the problems referred to above that prior art exists, the invention provides a kind of novel breaker interlock, its technical scheme taked is:
Comprise blocking lever, interlock bracket I, interlock bracket II, inter-locking panel I, inter-locking panel II, circuit breaker connecting rod and action bars, the bottom of interlock bracket I and interlock bracket II is separately fixed at the two ends, left and right of circuit breaker cradle, the card of inter-locking panel I and inter-locking panel II is erect and is placed, one end of action bars is successively through the center of circle of inter-locking panel I and the location hole of interlock bracket I, action bars and inter-locking panel I fix, and action bars can rotate in the location hole of interlock bracket I, interlock bracket II is fixed with pivot pin, the center of circle of inter-locking panel II is through pivot pin, inter-locking panel II can be rotated around pivot pin, this device also comprises connection locking block I, connection locking block II and connection locking block III, connection locking block I can rotate at this small sircle hole through the small sircle hole being positioned at inter-locking panel I upper left, connection locking block I is connected with inter-locking panel I by steady pin, connection locking block II can rotate at this small sircle hole through the small sircle hole being positioned at inter-locking panel II upper left, connection locking block II is connected with inter-locking panel II by steady pin, connection locking block III can rotate at this small sircle hole through the small sircle hole being positioned at inter-locking panel II lower right-most portion, connection locking block III is connected with inter-locking panel II by steady pin, blocking lever is horizontal positioned, the left end of blocking lever is threaded with connection locking block I, its right-hand member is threaded with connection locking block II, circuit breaker connecting rod is placed in vertical, the upper end of circuit breaker connecting rod is threaded with connection locking block III.
Two inter-locking panels of the present invention are connected together by a blocking lever, and three moves formation double crank kinematic system together, circuit breaker blocking lever can be driven to move up and down, and then control the divide-shut brake of circuit breaker, play the effect of security protection.Highly versatile of the present invention, can be applicable to most fixing cabinet, thus makes the mechanical interlocking between circuit breaker and mechanical latching become possibility, the very large fail safe that improve switch cubicle in Interlock Reliability between the two and this kind of situation.

Fig. 3 is B direction view of the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing.
As Fig. 1, shown in Fig. 2 and Fig. 3, the bottom of interlock bracket I 2 and interlock bracket II 3 is separately fixed at the two ends, left and right of circuit breaker cradle 7, the card of inter-locking panel I 4 and inter-locking panel II 5 is erect and is placed, one end of action bars 8 is successively through the center of circle of inter-locking panel I 4 and the location hole of interlock bracket I 2, action bars 8 and inter-locking panel I 4 fix, and action bars 8 can rotate in the location hole of interlock bracket I 2, the mechanical latching handle of the other end connecting switch cabinet of action bars 8, interlock bracket II 3 is fixed with pivot pin 9, the center of circle of inter-locking panel II 5 is through pivot pin 9, inter-locking panel II 5 can be rotated around pivot pin 9.Connection locking block I 10 can rotate at this small sircle hole through the small sircle hole being positioned at inter-locking panel I 4 upper left, connection locking block I 10 is connected with inter-locking panel I 4 by steady pin, connection locking block II 11 can rotate at this small sircle hole through the small sircle hole being positioned at inter-locking panel II 5 upper left, connection locking block II 11 is connected with inter-locking panel II 5 by steady pin, connection locking block III 12 can rotate at this small sircle hole through the small sircle hole being positioned at inter-locking panel II 5 lower right-most portion, and connection locking block III 12 is connected with inter-locking panel II 5 by steady pin.Blocking lever 1 is in horizontal positioned, the left end of blocking lever 1 is threaded with connection locking block I 10, and its right-hand member is threaded with connection locking block II 11, and circuit breaker connecting rod 6 is placed in vertical, the upper end of circuit breaker connecting rod 6 is threaded with connection locking block III 12, the divide-shut brake structure of its lower end connecting breaker.
Mechanical latching handle has three positions to be maintenance, work, disjunction locking respectively, when locking handle can drive action bars 8 to rotate when three positions switch as required, thus inter-locking panel I 4 rotates, inter-locking panel I 4 drives blocking lever 1 side-to-side movement, and the athletic meeting of blocking lever 1 drives inter-locking panel II 5 to rotate.The rotation of inter-locking panel II 5 can drive circuit breaker connecting rod 6 to move up and down, and then controls the divide-shut brake of circuit breaker, plays the effect of security protection.
