Control device of high-voltage switch

Abstract

The invention relates to the technical field of high-voltage power transmission, and discloses a control device of a high-voltage switch. The control device comprises a dust-proof box and further comprises a driving mechanism mounted at the bottom of an inner cavity of the dust-proof box; a positioning mechanism mounted at the right end of the rear side of the inner cavity of the dust-proof box; three opening and closing mechanisms mounted on the upper surface of the dust-proof box at equal intervals from left to right; and a protection mechanism mounted on the right side wall of the dust-proof box. The rotating shaft has a self-locking function, prevents a high-voltage circuit breaker from being restarted due to misoperation, avoids damage to related equipment or electric shock of personnel, is high in safety, can realize double sealing of a moving contact area, is stable in sealing performance, can prevent leakage from occurring in the high-voltage circuit breaker, and further enables the high-voltage circuit breaker to maintain good flame retardant performance. The arc extinguishing performance is ensured, fire disasters are avoided, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of high-voltage power transmission, in particular to a control device for a high-voltage switch. Background technique [0002] A high-voltage circuit breaker (or high-voltage switch) can not only cut off or close the no-load current and load current in the high-voltage circuit, but also cut off the overload current and short-circuit current through the function of the relay protection device when the system fails. Perfect arc extinguishing structure and sufficient breaking capacity can be divided into: oil circuit breaker (more oil circuit breaker, less oil circuit breaker), sulfur hexafluoride circuit breaker (SF6 circuit breaker), compressed air circuit breaker, vacuum circuit breaker device etc. The high-voltage circuit breaker is mainly composed of a diversion part, an arc extinguishing part, an insulating part and an operating part; [0003] High-voltage circuit breakers are generally divided into vac...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a control device for a high-voltage switch to at least solve the problem that the mechanical transmission components of the high-voltage circuit breaker in the prior art do not have self-locking ability, cannot avoid misoperation by staff, has poor safety, and is difficult to guarantee the sealing performance. The problem with the decline of arc ability
