JN10-12 Series indoor AC high voltage grounding switch
1. Product Description
JN10-12 series indoor AC high voltage grounding switch, for three-phase AC 50Hz, rated voltage 10KV power system, the overhaul as a guarantee of personal safety grounding device.
Earthing switch can be equipped with CS6-1 type practicing hand actuator or private practicing hand actuator.
2. Structure Introduction
Grounding switch to a three-phase device, a chassis fitted with three insulators fitted with terminals and ground contact on the insulator, through the bottom bracket spindle is rotated so that the earthing switch, closing.
Grounding switch is provided with a spring-closing devices, driven by the actuator, the spring energy storage to a first position so that the spring release of energy to achieve rapid grounding switch closing. Earthing switch optional high-pressure monitors charged, can also be interlocked with the switch means to achieve anti-misuse.
