High-voltage switchgear

 

JYN1-40.5(F) movable AC metal sealing compartmented switchgear is the indoor complete device for single busbar system of three phase current 50Hz, used to receive and distribute 35kV network of electric energy. This type of switch  cabinet has functions including prevent from wrongly operating breaker, prevent from pushing and pulling handcart with load, connecting ground wire with electricity, power transmission with ground wire and prevent from straying into   electrified compartment (hereafter referred to as "five protections".


Features of main structure:

1、 The inside of switch cabinet is mainly on basis of air insulation, and the insulating plate among rooms adopts flame retardant SMC materials;

2、 It has handcart recognition device on switch cabinet, the same type of handcart is interchangeable, and the different type of handcarts cannot be interchangeable;

3、 Switch cabinet adopt interlocking device with "five protection" functions, to be safe and reliable;

4、 It has reliable secondary locking device;

5、 The system scheme is complete, with strong universality.
