Earthing Switch For Switchgear refers to a mechanical grounding device that releases static charges from the equipment and circuit being repaired, and ensures the personal safety of maintenance personnel during power outage maintenance. It can withstand current for a certain period of time under abnormal conditions (such as short circuits), but it does not pass through load current under normal circumstances. It is usually part of the isolation switch.

(1) Grounding for normal operation during circuit maintenance. When the circuit breaker is located on a line that needs maintenance, the circuit breaker is in the open position, and the isolation switches on both sides are open and in the open state. The grounding switch is closed for normal operation grounding. To ensure the safety of equipment and maintenance personnel.
(2) Switch to electrostatic and electromagnetic induced currents. In two or more overhead transmission lines sharing the same tower or adjacent parallel arrangement, when a circuit or several circuits of lines are cut off, electromagnetic induction and electrostatic induction will be generated between them and adjacent live lines, and induced voltage and induced current will be generated in the cut off circuit. Therefore, grounding switches are used for such circuits.
(3) Close the short-circuit current. For grounding switches with rated short-circuit making current, they should be able to make at any applied voltage, including their rated voltage, and at any current, including their rated short-circuit making current. The rated short-circuit making current of the grounding switch is equal to the rated peak withstand current.
