Sampling system suitable for fault diagnosis of high-voltage circuit breaker

The invention discloses a sampling system suitable for fault diagnosis of a high-voltage circuit breaker. The sampling system comprises a signal acquisition unit, a signal preprocessing unit, a main control unit and a signal analysis unit, the signal acquisition unit comprises a plurality of sensors and a current regulator which are fixedly mounted on the high-voltage circuit breaker, and the sensors are used for monitoring a plurality of signals generated in the opening and closing process of the high-voltage circuit breaker; the current regulator is used for obtaining sensor data under different currents when the high-voltage circuit breaker breaks down. According to the sampling system suitable for fault diagnosis of the high-voltage circuit breaker, the system structure of the ARM and the industrial personal computer is adopted, and the industrial Ethernet is adopted for data transmission, so that the effect of improving the data transmission speed and the interoperability of the device is achieved. 本发明公开
