Research on the Operation and Status Monitoring Alarm Method of Distribution Network Circuit Breaker Based on Primary and Secondary Integration

As one of the key devices in the distribution network, enhancing the monitoring and alarming capabilities of the circuit breaker is an important foundation for promoting the digitalization and intelligentization of the electric power system. Currently, the monitoring and alarming capabilities of circuit breakers are still at the stage where the primary switches and secondary equipment are separated, and the integration of primary and secondary equipment has not been effectively achieved. This dissertation briefly introduces the current application status of circuit breakers. Starting from the main problem points of the products, it analyzes the focal points of the operation and status monitoring alarm method for distribution network circuit breakers based on primary and secondary integration, as well as the final system integration scheme.
