Abstract

To ensure the operation stability of DC Molded Case Circuit Breakers (MCCB), by analyzing the structure of DC MCCB and taking the internal electric field of DC MCCB as the research object, a finite element software Ansys Workbench is used to build and analyze the temperature field simulation model of DC MCCB. According to its internal the distribution of internal temperature and air flow, it is concluded that some plastic parts can hinder the internal air flow and affect the heat dissipation of circuit breaker. The simulation results show that the temperature rise of plastic parts and the maximum temperature of contacts can be effectively reduced by shortening the connecting plate of the upper cover and punching the bracket of the moving contact, so that the internal temperature will not be too high, which enhances the operation reliability of DC MCCB.
