[0002] Partial discharge refers to discharge that occurs between electrodes but does not penetrate the electrodes. It is caused by the presence of weak electricity inside the insulation of the equipment or defects caused during the production process. Repeated breakdown and extinguishing occur under the action of high electric field strength. When partial discharge occurs, it is necessary to use a partial discharge detector for detection. The partial discharge detector can sense the high-frequency signals generated by operating equipment failures, vibrations, leakages and electrical partial discharges. As the name suggests, high-voltage cabinets are equipment that connect high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers to low-voltage cabinets, and then to distribution boxes for various electricity users. The low-voltage cabinets are nothing more than electrical equipment that assembles some protective devices such as switches and circuit breakers into one. Some external line detection instruments of high-voltage cabinets are usually fixedly connected to the high-voltage cabinets, lacking protective devices, prone to failure, and inconvenient to replace.
