Earthing button in switch cabinet

The earthing switch in the low voltage switch cabinet is a kind of mechanical grounding device which is used to ensure the safety of the people. In the maintenance of electrical equipment, the grounding switch is closed to all directions may send electricity to power equipment or power equipment may produce induction voltage (or hang the earth), which is to prevent the maintenance personnel in power equipment (or power point) when suddenly calls, reliable safety measures to ensure personal safety, while remaining charge switch electrical equipment cabinet disconnect on, but also by the earthing switch on the ground and releasing.

Charged with grounding switch, grounding switch does not open the power supply, grounding switch is selected properly, and even some users do not install the grounding switch and grounding switch without demolition (usually incoming cabinet), this will be a serious threat to personal safety and the safe use of electricity, resulting in a vicious accident serious. But in recent years, due to the low pressure switch cabinet imported or the introduction of foreign advanced technology and manufacturing, as well as in our country in accordance with the "five anti" differences of low-voltage switchgear self-developed production and our products in the structure, in the maintenance of low voltage switch cabinet, the procedure often conflict with the "rules".
