Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a circuit breaker. The circuit breaker comprises a drive assembly, a circuit board assembly and a microswitch assembly, wherein the drive assembly is in drive connection with an opening and closing mechanism through a transmission gear set, so as to drive the transmission gear set to rotate and switch between a first rotating position and a second rotating position, and drive the opening and closing mechanism to switch between a closing position and an opening position; the circuit board assembly is electrically connected with the driving assembly; the microswitch assembly is arranged on the circuit board assembly, is electrically connected with the circuit board assembly and is used for detecting a rotating position signal of the transmission gear set; and when thecircuit board assembly determines that the opening and closing mechanism is not located at the corresponding closing position or opening position according to the detected rotating position signal, the circuit board assembly controls the drive assembly to drive the transmission gear set to continuously act, so that the opening and closing mechanism is located at the corresponding closing positionor opening position. According to the technical scheme, the opening and closing safety of the circuit breaker is effectively improved.

Description

technical field [0001] The invention relates to the technical field of electrical protection, in particular to a circuit breaker. Background technique [0002] At present, the opening and closing operation of traditional low-voltage circuit breakers mainly relies on manually pulling the handle to realize the opening and closing of the circuit breaker. The opening and closing state of the circuit breaker, but the accuracy of the opening and closing state of the circuit breaker displayed by the indicator light is not high. Hidden danger. Contents of the invention [0003] The main purpose of the present invention is to provide a circuit breaker, aiming at improving the safety of opening and closing of the circuit breaker. [0004] In order to achieve the above object, the circuit breaker proposed by the present invention includes a casing and a first terminal, a second terminal, an opening and closing mechanism and a transmission gear set respectively arranged on the casin...
