Abstract: At present, whether the convenient grounding wire is well grounded or not still adopted the method of manual observation, which has the disadvantages of cumbersome operation steps and inability to detect faults in time.In order to solve this problem, a new type of convenient grounding wire device was proposed based on the clamp meter method and the transmitting and receiving sensor.After being tested in the laboratory environment, the device can realize the real-time online test of whether the convenient grounding wire is successfully grounded, and upload the test results to the host computer in real time for preset standard judgment.Once the unqualified convenient grounding wire was detected, an early warning notice was issued immediately, which realized the intelligent detection and early warning function.In addition, global positioning system positioning system was inserted in the device to prevent the occurrence of power accidents caused by the omission of the ground wire device.The test results show that the new convenient grounding device not only improves the intelligence and automation level of operation, but also effectively improves the safety level of power maintenance personnel.
