Intelligent pluggable circuit breaker and monitoring and pre-warning system thereof

Abstract

The invention provides an intelligent pluggable circuit breaker and a monitoring and pre-warning system of the intelligent pluggable circuit breaker. The monitoring and pre-warning system is composed of the pluggable circuit breaker, a monitoring and pre-warning device, a portable terminal and a monitoring central server. The monitoring and pre-warning device comprises a measurement and control module, a temperature collection module, a voltage and current collection module, a communication module, a display module and an audible and visual alarm module. Pre-warning is achieved by measuring the temperature of all contacts in real time, measuring and calculating various electric parameters and comprehensively analyzing and judging the working state especially the unhealthy or abnormal state of the pluggable circuit breaker. In addition, the temperature warning function and the temperature protection function are achieved. The pluggable circuit and the monitoring and pre-warning device are highly integrated, the structure is simple, installation is convenient, safety and reliability are achieved, the intelligent running of the pluggable break circuit is achieved, the real-time running monitoring and production management of the field are facilitated, the low cost, production and refitting can be easily achieved, the fault rate and the damage rate of devices are effectively decreased, and the power supply reliability is improved.

Description

technical field [0001] The invention relates to an intelligent plug-in circuit breaker and its monitoring and early warning system, in particular to an intelligent plug-in circuit breaker with contact temperature protection, early warning and operation parameter record analysis and its intelligent monitoring and early warning system. It belongs to the field of intelligent electrical equipment. Background technique [0002] At present, the circuit breaker does not have an integrated intelligent electrical parameter measuring device. To solve this problem, a general-purpose electrical parameter measuring instrument is usually combined with it temporarily, and it is often impossible to install it because there is no reserved space, or it can only be installed due to the limited installation space. An instrument with a single function, and basically does not have the function of operating data recording and analysis. [0003] The traditional plug-in circuit breaker has a single...

AI Technical Summary

Problems solved by technology

At present, there is no intelligent plug-in circuit breaker system

[0005] In addition, in terms of safety in use, because the circuit breaker passes a large load current for a long time, the plug-in contacts are prone to overheating, and the contact parts of the contacts are affected by thermal oxidation or mechanical deformation, forming a vicious circle, resulting in contact failures. Problems such as overheating and burning occur from time to time. At present, the protection of the power system is aimed at the line and the electrical equipment connected to it, not directly at the circuit breaker body. Field operations often cause power outages due to short-circuiter contact failures. Therefore, It is necessary to monitor, protect and state early warning of overheating of circuit breaker contacts

At present, there are no relevant patents and technologies for the intelligent monitoring and early warning system for plug-in circuit breaker contact temperature protection, early warning and operation parameter record analysis
