Description

Technical Field

[0001] The present invention belongs to the technical field of electric power safety tools, and specifically relates to an integrated device for testing and grounding wires. The present invention also relates to a detection method for the integrated device for testing and grounding wires. Background Art

[0002] Electricity testing and grounding are essential parts of power outage inspection and maintenance, and are safeguards for personal and equipment safety. At present, the electricity testing for power outage inspection and maintenance is done manually. When the 10kV temporary grounding wire is connected to the overhead line of the distribution network, the electricity is tested with a tester first, and then the grounding wire is connected. There is a time interval. If the line has "reverse power supply" or "power transmission", it will cause the malicious operation of "hanging the grounding wire with power on", which poses a high risk of death by electric shock.

[0003] Moreover, the on-site ground supervisor cannot directly judge whether the operation is in place at close range, such as whether the operator has conducted the correct electricity testing, whether the quality of the testing is qualified, whether there is a "secondary check", whether the grounding is in place, whether it is hung on the insulation of the wire, or whether the moving contact of the grounding wire is fixed in place. These problems lead to accidents of "false electricity testing" and "false grounding" due to inadequate electricity testing and inadequate grounding. This is a safety technical issue that must be taken seriously. Summary of the invention
