Multifunctional circuit breaker detection device and method

The invention, which relates to the technical field of equipment detection, provides a multifunctional circuit breaker detection device and method. The device comprises an industrial personal computer, a detection module and a display module. The detection module comprises a same-period sub-detection module, an electric leakage protection characteristic sub-module, an action characteristic sub-module, molded case circuit breaker three-phase long time delay, three-phase short time delay and short circuit time delay detection sub-modules and a shunt excitation element and undervoltage release detection sub-module. The detection module detects a detected part, a detection result is transmitted to the industrial personal computer, and the detection result is displayed by the display module. The device and the method provided by the invention can be used for detecting various types of full-specifications and different-shell low-voltage electrical device elements including a miniature circuit breaker, a molded case
