Description

Technical Field

[0001] The invention belongs to the technical field of electroscope detection, and in particular relates to a multi-level electroscope detection device. Background Art

[0002] The electrometer plays an important role in urban rail transit. It can be used to detect whether rail electrical equipment and lines are energized, ensure the safety of maintenance personnel during inspection or maintenance work, and avoid electric shock accidents. When maintaining power supply equipment, substations, and contact networks, the electrometer can help technicians confirm whether the equipment is in a safe state and ensure that the power supply has been cut off before inspection. In the event of a power failure, the electrometer can quickly detect the fault location, help technicians quickly locate the problem, shorten the troubleshooting time, and improve the reliability of the system.

[0003] Before conducting an electrical test, the tester should first be confirmed on an electrical device to be in good condition. High-voltage switchgear in the urban rail transit industry generally adopts GIS closed installation. The electrical parts are wrapped in gas and cannot be contacted from the outside. Before conducting an electrical test, the tester can only be checked through its self-test switch to see if it is in good condition. Since the self-test circuit of the tester only includes secondary circuit verification and cannot simulate the actual voltage, the working status of the tester cannot be confirmed before the test. There is uncertainty in the test result, which poses a great safety hazard to equipment maintenance.
