Closed performance characteristics JYN1-35 AC metal withdrawable switchgear (hereinafter referred to as switchgear) Department of three-phase AC 50Hz indoor device of metal enclosed switchgear is used to power plant variable power system rated voltage 35kV, the maximum rated current for 1600, the highest voltage does not exceed 40.5kV single bus or single bus section of the complete distribution device. The switch cabinet can prevent misoperation circuit breaker, to prevent load push pull handle, prevent charged hang grounding lines, prevent take ground electrical transmission and prevent mistakenly charged interval (referred to as: "five anti"). The switch cabinet is interval type structure, the two part of the cabinet body and hand it by car with steel and steel plate bending welded components. The truck according to their use as the circuit breaker, arrester handcart, "Y" connection of voltage transformer handcart, "V" connection of voltage transformer handcart, single-phase voltage transformer handcart and station transformer handcart seven.
