Description

technical field [0001] The present application relates to the technical field of power equipment, and in particular to a physical simulation platform and a detection method for the detection of a grounding line selection device. Background technique [0002] With the increasing dependence of people's production and life on electricity, the safety and stability of the distribution network are becoming more and more important. In the low-current grounding system, when a ground fault occurs, it is difficult to determine the faulty line due to the small fault current. The method of manual pull test leads to a long fault processing time and a power failure of the non-faulty line. By installing the grounding line selection device, the faulty line can be directly determined, the fault handling time can be reduced, and the power failure range can be reduced. Therefore, the reliability of the grounding line selection device is very important. Because the fault characteristics of the...

Problems solved by technology

[0003] However, the existing way of testing the performance of the grounding line selection device is usually to directly apply an external signal to the grounding line selection device. The detection equipment of the grounding line selection device also has problems such as poor structural reliability or the inability to realize multiplexing, and because the technical level of each manufacturer is different, the products produced are uneven, so the existing grounding line selection device detection equipment cannot guarantee the grounding line selection Application reliability of the device
