Intelligent monitoring and protecting module of circuit breaker

Abstract

The invention relates to an intelligent monitoring and protecting module of a circuit breaker. The intelligent monitoring and protecting module comprises a voltage sensor, a current sensor, a temperature sensor, an electric energy quality chip, a microprocessor, a power supply module, an actuating mechanism and a communication module. The intelligent monitoring and protecting module is connected with the circuit breaker in series for use. The running stability and the health condition of the electric equipment and the circuit, the self health condition and the residual life of the circuit breaker and the potential risk of an electric system can be evaluated and prejudged by detecting the load state parameters, the circuit breaker performance parameters, the power consumption, the overloadcondition, the temperature rise and the electric energy quality. The intelligent level of circuit breaker protection function can be improved by a wide margin, and the safety and the reliability of power utilization are improved from multiple directions of a power distribution system, electric equipment and a circuit breaker.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, and more specifically relates to an intelligent monitoring and protection module for circuit breakers. Background technique [0002] The circuit breaker is an important control and protection device in the low-voltage power distribution system. It can quickly break the fault current when the power distribution system is overloaded or short-circuited to protect the power distribution system and electrical equipment. It can also be used for infrequent communication. interrupt control operation. The stability and reliability of circuit breaker performance are of great significance to the protection of power distribution system, electrical equipment and personal and property safety. [0003] However, traditional circuit breakers do not have power detection, communication, and remote control functions. People cannot monitor the status of circuit breakers and related power, which cannot meet ...

AI Technical Summary

Problems solved by technology

[0003] However, traditional circuit breakers do not have power detection, communication and remote control functions. People cannot monitor the status of circuit breakers and related power, which cannot meet the development needs of the smart home field.

Generally speaking, there is usually a large margin in the parameter selection of the circuit breaker and the power distribution system. Therefore, only when the short circuit or overload fault is serious, the circuit breaker can detect and perform the breaking operation, which is harmful to the power distribution system. and electrical equipment will cause a relatively large impact, affecting the complete power consumption

[0004] In addition, the circuit breaker needs to run for a long time since it is installed. With the accumulation of running time and breaking times, the electrical performance of the circuit breaker will inevitably deteriorate, and the service life will also be reduced accordingly. However, the existing circuit breaker Unable to detect its own electrical performance and remaining service life, there is a high potential safety hazard
