Indoor Electrical Ground Switch

main application

The Indoor Electrical Ground Switch is used in substations, power plants, and industrial electrical systems to safely ground electrical circuits during maintenance, testing, or repairs. Its main function is to provide a secure path for discharging any residual electrical energy from high-voltage equipment, ensuring a safe working environment for technicians.

In substations, the ground switch is used to ground switchgear, transformers, and circuit breakers before any maintenance or inspection work takes place. This prevents the risk of electric shock and equipment damage. In power plants, it is used to safely isolate and ground sections of the power grid, allowing maintenance crews to work on equipment without the danger of residual voltage or accidental energization.

The Indoor Electrical Ground Switch is designed for reliable operation in indoor settings, with insulation capable of withstanding high-voltage conditions. It typically features safety mechanisms like clear grounding status indicators and interlocks to prevent accidental operation, ensuring safe and efficient grounding during maintenance or emergency work.

The Indoor Electrical 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.
