The Research of Method of High Voltage Circuit Breaker Parameter Monitoring and Life Prediction

High voltage circuit breaker mechanical parameters of on-line monitoring is a technical difficulties, the mechanical parameter of breaker measurement with resistance sensor was put forward,obtained the characteristic curve of travel-time and speed-time,through the analysis of the data of displacement and processing, completed the calculation of breaker's travel,overtravel,closing speed and opening speed.All the data was transferred into the BPNN to obtain the remainder service life of the breakers set and give an alarm for the malfunction. The measurement accomplished measuring of diversified parameter in efficiency and nicety,reduced the time of measurement,improved the accuracy of measurement and took on the favorable foreground.
