The invention discloses an auxiliary switch device for an indoor high-voltage vacuum circuit breaker. The device comprises a circuit breaker body, a boss is arranged on one side of the circuit breaker body, a handle switch is arranged on one side of the boss, and a handle switch auxiliary device is arranged on the boss on the upper side of the handle switch; the handle switch auxiliary device comprises side plates, the side plates are located on the two sides of the boss, and the side plates are connected into a whole through a side connecting rod; the side connecting rod is located over the handle switch, a sliding guide block is arranged on one side of any one of the side plates, and one side plate and the sliding guide block are fixedly connected through a short rod. A circuit breaker switch can be easily shifted through the handle switch auxiliary device, and the problem that the circuit breaker switch is difficult to shift is solved; meanwhile, the cause that the circuit breaker is powered off can be judged according to the position of the handle switch auxiliary device, that is, whether the circuit breaker is powered off due to man-made causes or automatic tripping is judged.
Description
technical field [0001] The invention relates to a switch device, in particular to an auxiliary switch device for an indoor high-voltage vacuum circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a fuse-type switch. Combination with overheating and underheating relays, etc. Moreover, it is generally not necessary to change parts after breaking the fault current, and it has been widely used at present. However, in the prior art, the circuit breaker usually does not cut off the circuit artificially, but...
