Abstract
The utility model discloses a switchgear circuit breaker and isolator's interlocking device, sector plate I is fixed on the circuit breaker main shaft, the most advanced position of the face of sector plate II articulates the left end cabinet body branch, the upper end of blocking lever is left -leaning, and articulate on the face of sector plate I is close to the position on arc limit, the lower extreme of blocking lever articulates on the face of sector plate II is close to the position on arc limit, reset spring's right -hand member is fixed on the board of cabinet side, reset spring's left end roof pressure is on the border of II lower part hypotenuses of sector plate, the left end of cabinet body pin passes the reset spring inner space and fixes the left end at reset spring. The utility model has the characteristics of simple structure, interlocking safe and reliable, simple to operate, it is little to possess the space.
Description
Technical field
The utility model relates to a kind of interlock of circuit breaker.
Background technology
When operating GG-1A switch cubicle, there is the danger that on-load closes point isolating switch, in order to prevent hot line job, between breaker main shaft and cabinet Men Shoucao, increasing interlocking, with the safety of support personnel and equipment.Locking part realizes the interlocking of circuit breaker and isolation, just can close a point isolating switch when only having circuit breaker to be in gate-dividing state, closes deciliter isolating switch under preventing breaker closing state.
Summary of the invention
The purpose of this utility model is just to provide a kind of safe and reliable, interlock easy for installation, and its technical scheme taked is:
Comprise fanning strip I, fanning strip II, blocking lever, cabinet pin and back-moving spring, the tip location in the plate face of fanning strip I passes perpendicularly through breaker main shaft, and fanning strip I is fixed on breaker main shaft, the tip location in the plate face of fanning strip II is hinged on the left end of cabinet pole, the upper end of blocking lever is left-leaning, and the plate face being hinged on fanning strip I is on the position of arc-shaped side, the lower end of blocking lever is hinged on the plate face of fanning strip II on the position of arc-shaped side, the right-hand member of back-moving spring is fixed on side cabinet, the left end top of back-moving spring is pressed on the edge of fanning strip II bottom hypotenuse, cabinet pin is positioned at the below of cabinet pole, and cabinet pin is horizontal through side cabinet, the left end of cabinet pin passes back-moving spring inner space and is fixed on the left end of back-moving spring, the right-hand member of cabinet pin can block hand behaviour pivot pin.
The adjustable during assembling of this locking part is strong, and not by the impact of on-the-spot hand behaviour position, structure is simple, installs and convenient disassembly, when not using this interlocking, is pulled down by locking part, do not affect the use of circuit breaker from main shaft and hand behaviour fanning strip.The utility model has that structure is simple, interlock safety is reliable, easy for installation, occupies the feature that space is little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, the tip location in the plate face of fanning strip I 1 passes perpendicularly through breaker main shaft 6, and fanning strip I 1 is fixed on breaker main shaft 6, the tip location in the plate face of fanning strip II 2 is hinged on the left end of cabinet pole 7, the upper end of blocking lever 3 is left-leaning, and the plate face being hinged on fanning strip I 1 is on the position of arc-shaped side, the lower end of blocking lever 3 is hinged on the plate face of fanning strip II 2 on the position of arc-shaped side, the right-hand member of back-moving spring 5 is fixed on side cabinet 8, the left end top of back-moving spring 5 is pressed on the edge of fanning strip II 2 bottom hypotenuse, cabinet pin 4 is positioned at the below of cabinet pole 7, and cabinet pin 4 is horizontal through side cabinet 8, the left end of cabinet pin 4 passes back-moving spring 5 inner space and is fixed on the left end of back-moving spring 5.
When circuit breaker is in "on" position, fanning strip II 2 makes back-moving spring 5 compress, and the right-hand member of cabinet pin 4 can block hand behaviour pivot pin makes it extract, and then the operating grip on hand behaviour cannot rotate, and the conjunction that cannot realize isolating switch divides; When breaker open operation, breaker main shaft 3 drives fanning strip I 1 to turn an angle, and then the mobile fanning strip II 2 that drives of blocking lever 3 rotates, back-moving spring 5 is upheld left, and then drive cabinet pin 4 to move to left, the stop that hand behaviour pivot pin loses cabinet pin 9 can be extracted, and now isolated operation bar can be driven to move by the rotation of operating grip and the conjunction that realizes isolating switch divides.
