Reliability of the vacuum circuit breaker depends to a large extent the mechanical actuating system reliability

Reliability of the vacuum circuit breaker depends largely on the mechanical reliability of the actuator system. International Conference organized international survey shows that a large grid in a vacuum circuit breaker failure, mechanical failure (including the actuator and control circuit) accounted for more than four-fifths of all the failures, other arcing, insulation faults occupy a smaller proportion lower heat failure ratio.  Voltage stabilizer  factory inspection and  electric meter  test users, regarded as an important test of the mechanical properties of the pilot project. Based on the analysis of research results and trends on the domestic circuit breaker monitoring, developed the mechanical properties of the vacuum circuit breaker testing device based on DSP. First, the mechanical  power transformers  of the vacuum circuit breaker test parameters were analyzed, and then introduces the mechanical properties of the vacuum circuit breaker test equipment hardware and software design, hardware design. Firstly, the instantaneous signal responsive to the Hall current sensor actuator aggregate, the current signal tripping coil; using linear displacement sensors measure the moving contact trip signal, and converts it into a voltage signal synchronization output;
