Research on the reliability test control system's design of the miniature circuit breaker

This paper describes the miniature circuit breaker's hardware and software design of the reliability test device, which is based on the reliability criterion. The device could be used to fulfill the reliability test of miniature circuit breaker. The control system has a high level of automatic control and the capacity of failure processing. The measurement accuracy and speed are improved greatly by using the 32-ch Isolated Analog Input Card PCI-1713 which is based on the technique of FIFO to complete the acquisition of the contact voltage.
