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

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.
