Earthing Switch

The dielectric insulation requirements of Sangao high quality earthing switch is the same as those of its associated disconnector. Similarly, the earthing switch also needs to match the short-time fault/short-circuit current withstand capacity of its associated disconnector. In addition, the earthing switch used for transmission line switching needs to disconnect the electromagnetic induction and electrostatic capacitance current induced by the adjacent line/circuit

In the substation, the earthing switch is used in conjunction with the disconnector (the earthing switch can also be independent). The earthing switch (earthing disconnector) is used to enable the corresponding part of the circuit (and the equipment connected to it) to enter and work safely so that it reaches the ground potential. The operation of the earthing switch is interlocked with the disconnector to prevent erroneous operation, that is, the contacts are closed when the circuit is energized.

The earthing switch is usually integrated into the integral assembly of the disconnector, or is a separate (independent) device with its own supporting structure. However, integration into the disconnector is a more common design.

High Voltage Grounding Switch

The main function of the High Voltage Grounding Switch in the switch cabinet is to protect the technicians and the switch cabinet from accidental operation. It can be closed to prevent short-circuit current. When a line grounding fault occurs, the grounding switch can provide a grounding fault current source. Please choose Sangao high quality High Voltage Grounding Switch to reduce your work troubles!

High Voltage Earthing Switch

Sangao high quality High Voltage earthing Switch is also called earthing switch. Earthing switch and earthing switch are used interchangeably. It is a protective device included in switchgear components such as circuit breakers and isolators. When the circuit breaker is removed and shaken out, the earthing switch automatically grounds the busbar section close to the circuit breaker. For isolators, the earthing switch contacts the busbar when the isolator isolates the circuit, releasing any charge that may have accumulated there.
