Circuit breaker fault tripping indicating mechanism

Abstract

The invention discloses a circuit breaker fault tripping indicating mechanism, which comprises a shell, a tripping mechanism and an indicating mechanism, wherein the tripping mechanism and the indicating mechanism are arranged on the shell, the tripping mechanism comprises a tripping groove and a circuit groove perpendicular to the tripping groove, the tripping groove is internally provided with an electromagnet and a tripping rod, the top of the tripping rod is sleeved with a tripping spring, the other end of the tripping spring is fixedly connected with a gasket, the indicating mechanism comprises a Hall sensor, an indicating lamp, an electromagnetic switch, a distance sensor and a button cell, and a lead screw motor is fixedly mounted in the circuit groove. The beneficial effects are that a fault indication function is added to the circuit breaker, in a use process, whether the current tripping is fault tripping or not can be judged through the indicating lamp when the circuit breaker is changed from a closing state to an opening state in the using process, and the indicating mechanism controls the electromagnetic switch to be separated through the Hall sensor and the distance sensor at the same time, so that the lead screw motor assists the tripping rod in forcibly separating from a main circuit, the indicating lamp is turned on to play a role in reminding, and manual separating can be achieved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker fault trip indicating mechanism. Background technique [0002] The fault circuit breaker is used to quickly cut off the circuit and issue instructions at the same time when the line or electrical equipment fails. The fault type is, for example, an overcurrent fault or an electric leakage fault. Residual current operated circuit breaker (RCBO) is a commonly used fault circuit breaker, which can integrate the detection function of overcurrent fault and leakage fault, and is widely used in various household and industrial occasions. In actual use, for both overcurrent faults and leakage faults, the RCBO will act to cut off the circuit, so the user cannot tell what kind of fault caused the circuit to be disconnected. [0003] In addition, usually when the RCBO detects a fault, the alarm light will be turned on, but because the RCBO will also send a trip s...

AI Technical Summary

Problems solved by technology

In actual use, for the two types of faults of overcurrent fault and leakage fault, RCBO will act to cut off the circuit, so the user cannot tell what kind of fault caused the circuit to be disconnected

[0003] In addition, usually when the RCBO detects a fault, it will turn on the alarm light, but because the RCBO will also send a trip signal when the fault is detected, the circuit will be cut off, so that the power supply of the alarm light will also be cut off, thus indicating the fault. The warning light cannot keep on constantly, which also causes inconvenience to use

Not only that, if a fault occurs when the circuit is cut off, it will be dangerous because the circuit is not cut off in time
