Indoor high-voltage isolation switch GN24-12D/SD/CD/CSD-630A~1250A

The GN24-12D series indoor high-voltage isolation switch with grounding knife (hereinafter referred to as the isolation switch) is an indoor high-voltage switchgear with a rated voltage of 12kV and below, three-phase AC 50Hz, used for breaking and closing circuits in power systems with voltage and without load. The GN24-12D series isolation switch has three working positions: closing, opening, and grounding, and can operate in steps. It has the anti error performance of preventing live hanging of grounding wires and closing with grounding. It is used in the KGH-12 type metal armored fixed switchgear, and also serves as an improvement on switchgear such as GG-1A (F), making it an essential component to meet the "three protection" requirements. The grounding contact knife can be used to close the grounding contact knife according to the requirements of the "Safety Work Regulations" during power outage maintenance of electrical equipment, create artificial short circuits in the network, and ensure that maintenance personnel receive reliable "ground potential" protection. As one of the main measures for electric shock injuries.
