main application

The AC Grounding Switch for High Voltage is used in substations, power plants, and industrial electrical systems to safely ground high-voltage circuits during maintenance, repairs, or testing. Its main function is to provide a reliable path for discharging residual electrical energy from high-voltage equipment, ensuring the safety of personnel and equipment during maintenance activities.

In substations, the grounding switch is employed to isolate and ground high-voltage components such as circuit breakers, transformers, and switchgear, protecting maintenance workers from electrical shock hazards. In power plants, it ensures that sections of the electrical grid or power distribution systems are safely grounded before performing maintenance, preventing accidents related to residual voltage or inadvertent energization.

The AC Grounding Switch is built to handle high-voltage environments and is equipped with safety features such as clear indication of grounding status and interlocking mechanisms to prevent accidental operation. It ensures safe, fast, and reliable grounding, improving safety and operational efficiency during maintenance, repair, or emergency situations.

The AC grounding 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.
