Research on an Online Monitoring and Diagnosis System of High-Voltage Circuit Breaker

Abstract:

The principle of an online monitoring and diagnosis system suitable for various kinds of High-voltage Circuit Breakers (HVCB) is presented in the paper. The system consists of distributed data acquisition devices, a communication system based on field bus, and a host based on B/S structure. The research presents the methods to select the main monitoring signals of high-voltage circuit breakers, to acquire data, and to calculate operational feature values, as well as realizes high-speed process to monitoring signals, valid online monitor to high-voltage circuit breakers, and fault diagnosis.
