Indoor High-Voltage Switchgear Ground Switch

main application

The Indoor High-Voltage Switchgear Ground Switch is used in substations, power plants, and industrial electrical systems to safely ground high-voltage switchgear during maintenance, repairs, or testing. Its primary function is to provide a secure path for discharging any residual electrical energy from high-voltage equipment, ensuring the safety of technicians and preventing electrical hazards.

In substations, the ground switch is employed to isolate and ground high-voltage components like circuit breakers, transformers, and isolators before any maintenance work begins. This prevents the risk of electric shock and equipment damage during servicing. In power plants, it ensures that electrical systems are properly grounded when isolating parts of the power grid or other high-voltage equipment for maintenance, upgrades, or emergency repairs.

The Indoor High-Voltage Switchgear Ground Switch is designed for reliable, fast operation in indoor environments. It is equipped with safety features such as clear grounding status indicators, interlocking mechanisms, and manual or automatic operation, ensuring the switchgear is safely grounded and that work can proceed without the risk of electrical accidents.

The Indoor High-Voltage Switchgear Ground 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.
