Fault Diagnosis and Monitoring Device Design for the Electrical Life Test of Low Voltage Circuit Breaker

In the electrical life test, the low voltage circuit breaker may have a variety of faults. At present, that lacks effective fault diagnosis method and monitoring device. To solve the above problem, the method of fault diagnosis and the design of monitoring device are proposed in this paper. The method of fault diagnosis includes the collection of test parameters and the model establishment of fault diagnosis. Based on the fault diagnosis model, the electrical life test monitoring device is designed. The device is used to collect the test data in real time, and analyzed the logic to determine whether the fault occurred during the test. When the fault occurred, the device will automatically take protective measures. In order to improve its intelligence, the intelligent monitoring device is designed based on Device net bus technology. It has been implemented in the Device net control network and has the function of Internet of things. So the real-time monitoring test process of remote network can be realized.
