Abstract

The invention discloses a circuit breaker, and belongs to the electrical field. The circuit breaker comprises a shell, an operation module, a function module, a tripping module and an electric leakage detection module. The tripping module comprises a first tripping piece, a transmission piece, a tripper, an operation module and a moving contact, the first tripping piece and the transmission piece are hinged to the shell, and the first end of the operation module abuts against the moving contact and the first tripping piece of the function module at the same time; the electric leakage detection module is electrically connected with the function module and the release so as to transmit electric leakage information to the release. When the circuit breaker is switched on and switched off, the moving contact and the first tripping piece are driven by the operation module to rotate, the first tripping piece does not make contact with the transmission piece, when the circuit breaker is subjected to leakage protection, the tripper drives the transmission piece to rotate, the transmission piece abuts against the first tripping piece and drives the first tripping piece to rotate, and the first tripping piece drives the operation module to move to be separated from the moving contact. The circuit breaker has the advantages of few parts, small size, simple structure, high working reliability and the like, and is favorable for being designed into a one-bit wide circuit breaker.

Description

technical field [0001] The present invention relates to the electrical field, in particular to circuit breakers. Background technique [0002] A circuit breaker is a circuit protection device, which is usually used to cut off and connect the load circuit and cut off the fault circuit. In order to realize the leakage protection of the circuit, the circuit breaker usually has the leakage protection function. Exceed the set threshold to control whether the circuit breaker is automatically switched from the closed state to the open state. [0003] However, the current circuit breaker with leakage protection function has at least the following problems: a large number of parts make the internal structure of the circuit breaker complex, the volume is large, and the operation reliability of each part is poor. Especially for a one-position circuit breaker with a width of 18mm, it is extremely difficult to add a leakage protection function due to its width limitation. SUMMARY OF T...
