Purpose:JYN1-40.5 type interval AC metal enclosed switchgear is an indoor complete set of equipment for three-phase AC 50Hz single busbar system, used for receiving and distributing 40.5kV network power. This switchgear has the functions of preventing misoperation of circuit breakers, preventing pushing handle carts with loads, preventing live hanging of grounding wires, preventing grounded power transmission, and preventing accidental entry into live compartments (referred to as "five protections").
Structural features:This switchgear is an indoor protective complete set of equipment, consisting of a cabinet body and a handcart. The cabinet is made of angle steel and steel plate bending and divided into handcart room, busbar room, isolation contact room, cable room, relay room, and terminal room. The handcart room is separated from the isolation contact room and cable room by a partition made of insulating material and equipped with an insulation valve. The other rooms are separated by grounded metal, belonging to the interval enclosed switchgear. |
