MV switchgear
KYN550-1Armored metal enclosed withdrable switchgear
 

VniGear/KYN550-1Armored metal enclosed withdrable switchgear equipment suitable for three-phase AC 50Hz, 12kV indoor distribution system. As the acceptance and distribution of network power, and the implementation of the circuit control, protection and monitoring. Products meet the GB3906, DL/T404, IEC62271-200 standard requirements, and has a perfect "Five" function.

This product uses the latest structural modular design concept, the cabinet body is divided into three modules, power room module, bus room module, cable room module, can be a variety of program modules composed of various schemes by the cable room module independent of changes, change, or any combination of module power room and base line room module changes. The structure adopts tibnor by multiple bending assembly. VniGear550 series switch devices can be on-site installation, cable room module and bus room module, power module and power room, room module can be hand car back to the location of the trial after the overall removal in maintenance, remove the power room module can be closed after removing partition module and bus room cable room module. Transformer module can bus module and cable room in front of the bus room maintenance, so as to completely achieve the real purpose of the front wall mounting maintenance. Through the observation window of the front and rear door panels, it is convenient to observe the state of the circuit breaker, the position of the vehicle, the state of energy storage of the mechanism, the position of the earthing switch and the connection of the cable head. The cable room has enough space to connect a plurality of cables.

VniGear550 series switch equipment for the middle shift open structure, can be in the bus room module, cable room module combination or out, can be equipped with circuit breaker, PT, isolation, fuse and other middle modular car.
