Abstract

The invention discloses an operating mechanism of a leakage circuit breaker. The operating mechanism comprises a handle operating mechanism, a fixing frame, a lateral baffle plate, a moving contact frame and a tripping device, wherein the handle operating mechanism comprises a handle, a handle resetting spring and a transmission frame linked and matched with the handle; the transmission frame is matched with the moving contact frame in a transmission connection manner; and the tripping device comprises a tripping mandril. The operating mechanism is characterized by also comprising a gear rod,a kick frame, a kick frame resetting spring, an on-off indication frame and a resetting plate. The operating mechanism has the advantages that: the indication of an on-off state and a leakage state is realized; meanwhile, the operating mechanism can act by matching with an auxiliary switch without extra circuit connection; and therefore the operating mechanism has the advantages of reasonable structure arrangement, operation stability and reliability and convenience for overhauling.

Description

technical field [0001] The invention relates to a leakage circuit breaker, in particular to an operating mechanism of the leakage circuit breaker. Background technique [0002] The leakage circuit breaker is a switch that can automatically trip when the leakage current in the circuit exceeds a predetermined value, thereby providing leakage protection. The structure of the existing leakage circuit breaker is mainly composed of a circuit breaker and a release unit. [0003] Existing leakage circuit breakers generally indicate the leakage state and on-off state of the leakage circuit breaker by installing a plurality of working indicator lights connected to the inside of the leakage circuit breaker. During maintenance or production inspection of this kind of leakage circuit breaker, once an indication fault occurs, the circuit inside the leakage circuit breaker needs to be overhauled, and the repair and maintenance costs are high, which is not conducive to cost control. Cont...
