Design of high precision detecting system for Vacuum Circuit Breaker

With the increasing of used quantity and voltage label of vacuum circuit breaker (VCB), the stability and reliability of VCB have very important significance for the reliable running of transmit electricity system. How to detect the mechanism characteristics of VCB, and obtain the characteristic parameters through the detecting data, and obtain the regularity of status examine and repair of VCB through the characteristic parameters, becomes more and more focus of research. Based on the prophase research, a high-precision and high-speed detecting system for mechanism characteristic and electric characteristic of VCB is designed in this paper. The detecting system includes two parts, one is the high-speed data sampling system, the other is the data disposing system. The high-speed data sampling system is made of DSP that achieves sample to various high speed signals, and uploads the sampled data to data disposing system through the way of data bus. Through the analysis of the uploaded data, the characteristic parameters are obtained in the data disposing system. The mechanism status is obtained through the characteristic parameters. So it carries out the exactly analyze of running status and also develops the steadily running of power transmission system.
