High-Voltage AC Switch for Grounding

main application

The High-Voltage AC Switch for Grounding is used in substations, power plants, and electrical distribution systems to safely ground high-voltage circuits during maintenance, repairs, or testing. Its primary function is to provide a secure grounding path for high-voltage equipment, ensuring that any residual electrical energy is safely dissipated before work begins, protecting personnel and equipment.

In substations, the switch is employed to ground switchgear, transformers, or circuit breakers before maintenance or inspections, preventing electrical shock hazards and ensuring safe working conditions. In power plants, it is used to safely isolate and ground parts of the power grid, ensuring that maintenance crews can work on equipment without the risk of electrical accidents.

The High-Voltage AC Switch for Grounding is built to handle high-voltage conditions and is equipped with safety features like grounding status indicators, interlocking mechanisms, and manual or automatic operation. These features ensure the switch operates reliably and safely in demanding environments, enhancing overall safety and operational efficiency during maintenance activities.

The high-voltage AC switch is an internationally advanced product developed by advanced technology, whose structure is assembly. After comprehensive assessment, the performance meets the requirements of GB1985-2004 AC high voltage isolating switch and grounding switch and IEC62271-102:2002, which is applicable to 3-12KV three-phase AC 50Hz power system; it has short-circuit off-off capability to protect other electrical equipment in the switchgear from damage, and can be used with various high voltage switchgear, or as grounding protection during maintenance of high voltage electrical equipment.
