Title:
CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2022/126830
Kind Code:
A1
Abstract:
The present application discloses a circuit breaker. The circuit breaker comprises a driving assembly, the driving assembly being connected to an opening-closing mechanism in a driving manner by means of a transmission gear set, so as to drive the transmission gear set to rotate and switch between a first rotation position and a second rotation position, and to drive the opening-closing mechanism to switch between a closing position and an opening position; a circuit board assembly, the circuit board assembly being electrically connected to the driving assembly; and a microswitch assembly, the microswitch assembly being arranged on the circuit board assembly and being electrically connected to the circuit board assembly, and being configured to detect a rotational position signal of the transmission gear set; when the circuit board assembly determines, according to the detected rotational position signal, that the opening-closing mechanism is not in the corresponding closing position or opening position, the driving assembly is controlled to drive the transmission gear set to continue to operate, so that the opening-closing mechanism is in the corresponding closing position or opening position. The technical solution of the present application effectively improves the safety of open and close of the circuit breaker.
