The invention relates to the technical field of circuit breakers, in particular to an anti-misoperation locking device of a circuit breaker. The device comprises the circuit breaker, a handle hole is formed in the left end of the circuit breaker, an operation handle penetrating through the handle hole and extending to the outside is arranged in the circuit breaker, and a warning assembly is fixedly installed on the lower portion of the left end of the circuit breaker. According to the invention, through arrangement of a mounting assembly, a torsion spring drives a connecting rod to rotate in a second cylinder and a second through hole, the connecting rod rotates to drive a fixing rod to rotate, the fixing rod rotates to push an operating handle upwards, and when the operating handle pushed upwards falls down again, it is indicated that a circuit goes wrong first; when the operating handle pushed upwards does not fall downwards, the circuit breaker is mistakenly locked, at the moment, the circuit breaker can quickly restore the circuit to guarantee use of a user, the circuit can be quickly restored to guarantee normal use of the user, and many troubles are brought to the user due to long-time power failure caused by mistakenly locking of the circuit breaker.
Description
technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker anti-misoperation locking device. Background technique [0002] The circuit breaker is an important part of the electrical industry and has been widely used. When the electrical circuit is working normally, the circuit breaker can achieve functions such as power failure, power supply and conversion circuit by closing or disconnecting the circuit that supplies electric energy; When abnormalities such as overload and short circuit occur in the circuit, the circuit breaker will trip to cut off the electrical circuit, so as to avoid endangering the safety of workers and the normal operation of equipment due to circuit failure. [0003] However, when the current circuit breaker is in use, due to some environmental or other factors, the circuit breaker is accidentally locked. Time, so now a kind of circuit breaker anti-misoperation locking device is needed. ...
