A control device for a high voltage switch

Abstract

The invention relates to the technical field of high-voltage power transmission. The invention discloses a control device for a high-voltage switch, which includes a dust-proof box, and further includes: a driving mechanism installed at the bottom of the inner cavity of the dust-proof box; a positioning mechanism installed at the bottom of the inner cavity of the dust-proof box; The rear right end of the inner chamber of the dustproof box; the number of opening and closing mechanisms is three, which are equidistantly installed on the upper surface of the dustproof box from left to right; the protection mechanism is installed on the right side wall of the dustproof box . The rotating shaft of the present invention has a self-locking function, which prevents the high-voltage circuit breaker from restarting due to misoperation, avoids damage to related equipment or electric shock to personnel, and has high safety. Moreover, double sealing of the moving contact area can be realized, and the sealing performance is stable, which can prevent high-voltage There is leakage inside the circuit breaker, so that the high-voltage circuit breaker maintains good flame-retardant performance, and the arc-extinguishing performance is guaranteed to avoid fire and prolong its service life.

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...
