Protecting equipment of circuit breaker

Abstract

The invention discloses protecting equipment of a circuit breaker. The protecting equipment comprises a shell, a base and an internal circuit, the base is arranged at the bottom of the shell and is fixedly connected to the shell, the internal circuit is arranged at the upper end of the base and is installed on the base, and a display screen is arranged in the middle of the shell and is embedded onthe shell. The protecting equipment is provided with a temperature detector and an infrared detector, when the circuit breaker works, the working temperature of the whole circuit breaker can be detected, and when the working temperature of the circuit breaker changes drastically, and if the circuit breaker still not breaks a circuit, a mechanical arm is called for physical operation to break thecircuit; the protecting equipment is provided with a rectangular wireless module, an electromagnetic sensor, a rectangular wireless module, the temperature detector, the infrared detector, a circuit board and a steering engine are all electrically connected, and the working state of the circuit breaker can be sent to a user mobile phone through the rectangular wireless module.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to protection equipment for circuit breakers. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into For high-voltage circuit breakers and low-voltage circuit breakers, the division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. When they It can automatically cut off the circuit in the event of serious overload, short circuit and undervoltage faults. Its function is equivalent to the combination of fuse switch and overheating and underhe...

AI Technical Summary

Problems solved by technology

[0003] However, the existing circuit breaker protection equipment is not equipped with electromagnetic detection equipment, and the armature for internal control on-off is prone to rust and jamming failure, resulting in failure to disconnect the circuit in time and causing a fire. There is no mechanism for detecting temperature, and the internal overload cuts off the power When the mechanism fails, the circuit cannot be disconnected in time, and after the circuit fails, it cannot be known in time and repaired in time
