Grounding device plays a very important role in the safe operation of power supply system, the grounding device is buried in the ground grounding electrode and the grounding electrode to collectively by connecting wire between devices, due to the insulation of electric equipment damage. The strip of electrical equipment on the metal shell and cable will produce high voltage, grounding protection and so important, to avoid personal electric shock accidents, ensure the safety of the people. In the grounding device because the work is not in place, the construction of electrical safety problems will appear in the use process, so we should give the grounding device of electrical equipment in the daily operation and maintenance work with full attention, focusing on the analysis of the existing problems, and make an important measure to ensure the normal operation of electrical equipment and safety the door.
