Abstract
The utility model relates to a power circuit ground connection detects technical field, is an equipment ground signal's accurate monitoring devices of removal. Including insulator spindle, earth connection and earth fault indicator, be fixed with the earth connection in the upper end of insulator spindle, the earth connection is opening arc down, is connected with earth fault indicator in the outer end of earth connection. When the distribution network line is abnormally grounded, a power supply maintenance worker holds the insulating rod, the grounding wire is hung on each branch line, the branch line of the line is tested (without climbing a pole) through the ground fault indicator, the branch line with the grounding is searched, and the pole is climbed to disconnect the branch line after the branch line with the grounding is searched, so that the pole climbing time is reduced, the problem that a breaker needs to be pulled to detect a specific grounding signal is solved, the grounding detection efficiency is greatly improved, and the potential safety hazard of equipment damage and tripping on the line caused by long-time ground fault detection in the prior art is reduced.
Description
Technical Field
The utility model relates to a power circuit ground connection detects technical field, is an equipment ground signal's accurate monitoring devices of removal.
Background
