The output end of the receiving module is connected with the input end of the storage module, the output end of the storage module is connected with the input end of the processing module, the output end of the processing module is connected with the input end of the display module, and the display module and the power-on module work in a matched mode.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a secondary fusion complete set of pole-mounted circuit breaker synchronous measurement system and a detection method thereof. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy and start asynchronous motors infrequently. It can automatically cut off the circuit when serious overload, short circuit and undervoltage faults occur. Its function is equivalent to t...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing circuit breakers on the market need to detect AC, DC and contacts during the actual measurement process, and the staff need to check and measure AC from the power supply, check and measure DC from the coil, and check the contacts from the relay. Therefore, the staff need to check the AC, DC and contacts from three different places, which takes a long time and is inefficient.
