Novel HV Circuit Breaker Reliability Testing Measure Based on Image Processing
Aimed at the difficulty of sensors installation in high-voltage (HV) circuit test experiment, a novel image processing based measure is put forward to detect the mechanical parameters. Through the on-off action images were captured by digital camera with the HV circuit breaker switching, the moving contact travel parameter can be calculated from image analyzing. At the meantime, the necessary timing or interval parameter can be calculated by the electrical signal processing. So most of other key mechanical characteristic parameters, include moving contactor trip, average velocity, bounce frequency, switching time-consuming and over-travel etc., can be also derived associated with the moving travel parameter and time-signal set. It is a non-contact measurement method, which can instead of grating sensor installed on the HV circuit breaker. Experiments result that this new method can obtain the HV circuit breaker mechanical parameter accurately, and it can increase the testing automatic level greatly.
