Document Type and Number:
WIPO Patent Application WO/2022/135037
Kind Code:
A1
Abstract:
The present invention relates to an electrical leakage tripping mechanism of a circuit breaker, which comprises a circuit breaker housing, a tripping device and a linkage unit located in the circuit breaker housing, wherein the linkage unit comprises a lever and a pull rod; the lever is hinged in the circuit breaker housing, and two ends of the lever are formed with a pull rod toggling end and a tripping device driving end respectively; the pull rod is slidably arranged in the circuit breaker housing; the tripping device driving end corresponds to the position of the tripping device; the tripping device can push the tripping device driving end to enable the lever to swing; a lockout abutting surface is disposed on the pull rod; the pull rod toggling end can prod the pull rod to slide; and a restoring spring for restoring the lever is also comprised. By means of the technical solution above, provided in the present invention are the electrical leakage tripping mechanism of the circuit breaker, which is small in overall volume, is convenient to install, and has good stability.
