Intelligent design of micro circuit breaker with electrical-energy measurement and self-diagnosis

Abstract

Energy consumption in various occasions is required to be managed and controlled finely. Traditional micro circuit breakers are mainly used for overload and short-circuit protection of distribution lines, which cannot meet the requirements of fine management and control of energy consumption. In order to achieve this goal, an intelligent micro circuit breaker is proposed in this paper to meet the requirement of new power systems and integrate functions of wireless communication, power measurement and equipment diagnosis. The circuit breaker can be remotely controlled according to users’ command, and the power consumption can also be monitored and measured in real time. The intelligent micro circuit breaker has a temperature measurement module for defect self-diagnosis such as poor contact of connectors of the circuit breaker. These functions indicate that the proposed design has good practical application value.
