[0002] Integrated protection devices offer superior protection, control, and diagnostic capabilities. They can collect and process a wealth of data in a timely manner. This data not only enables comprehensive analysis of the power system but also identifies potential hazards, enabling preventive measures and improving automation. The overall device's safety, speed, sensitivity, and selectivity are crucial to the power system.

[0003] The normal service life of the integrated protection device is 6 years. When the substation replaces the integrated protection device, we need to establish channels and debug the integrated protection device to ensure that the device can work properly. When the substation repairs the high-voltage equipment, we need to conduct simulation tests on the integrated protection device to ensure that the equipment functions normally. At present, the operating method for the test is manual short-circuit test, which is extremely harmful and can easily damage the internal structure and circuit of the device. In serious cases, it may even cause personal electric shock safety accidents. Moreover, each work can only be carried out after the wiring installation personnel complete the work and the device is powered on. We can then carry out communication wiring, import templates, databases, associate points, and work on the points. This seriously affects the power supply time of the equipment and makes work efficiency low. Utility Model Content
