Product Description

 

JN22-40.5/31.5 Series of Indoor High Voltage Earthing Switch for Circuit Breaker

 
1.General description
JN22-40.5/31.5 indoor high voltage grounding switch (hereinafter referred to as earthing switch)is an indoor grounding device suitable for rated working voltage 40.5KV and three-phase AC Hz.The performance of the product not only meets the requirements ofGB1985-89"AC high-voltage isolating switch and earthing switch", but also meets the requirements ofIECI129.Theutilitymodel has the advantages of advanced design,reliable technical performance,simple structure,convenient installation and dispatching,etc..The utility model can be used as an armored open type AC metal enclosed switch device for 35KV,and can also be used for the grounding of the high-voltageelectrical equipment.The earthing switch has a high closing capacity.The mechanical interlockmechanism is used between the grounding switch and the main switch,between the handcart and the door,to meet the "five prevention"function.
