XGN2-12 Indoor Box-type Fixed Metal Enclosed Switchgear Cabinet
XGN2-12 Box-type fixed metal-enclosed box switchgear cabinet is developed and designed of high voltage switchgear assembly by us. The cubicle framework is made of C profiles and G profiles with pleasing outline, which facilitates production control and shortens production period.
XGN2-12 switchgear is a protective fixed metal-enclosed box switchgear, which can widely used in high voltage motor with moving, switching operation and other occasions. It can be frequent operation, no explosions, fires and other dangerous.Main characteristics
This switchgear is metal-enclosed box switchgear, the cubicle framework is made of C profiles and G profiles, inside cubicle is use metal plates divided into circuit breaker room, busbar room, cable room and relay room. And user can observe the operation of the main components of the cabinet through the observation window and the lights on the facade.
According to the cabinet layout, the front upper part is relay room, inside room can be installed relay, the door can be installed un-signal realy, indicating instrument, signal lamp, switches can be installed in the operating room. The back upper part is busbar room, the back lower part is cable room which can be easily wiring. The front part is circuit breaker room, which can be convenient for switchgear maintenance. Protection class IPzX
1.The cabinet does not use any form of insulation partition of phase or relative. The inside is air insulated and the distance of air insulation of phase to phase and phase to earth shall be greater than iz5mm. Supporting insulators (or bushings) of greater creepage are employed to make the switchgear have greater insulation level and stronger insulation stability;
2. It using rotary isolating switch, this isolating switch will rotate conductor to earth on segmented. position, that is、 to form a “metal separation”(two docking interface) between the charged body (main bus) and the isolated conductors(charged body can only discharge phase to phase or tolike circuit breakers). At this time, the earth, without affecting the isolation conductor, thus ensuring the satety of the maintenance personnel.
3. The wiring terminals of cable shall have a distance of 60o-8oomm from the ground as to tacuitate the making, mounting, mounting and maintaining of the cable. i ower rubber gasket is used to seal between cable compartment and cable chute as to prevent dampness or small animals from entering the cubicle via the chute.
4. Compulsory mechanical locking method is employed in the interlocks among main switches, disconnectors, earthing switches and cubicle door to meet the “five-proof” interlock function. During the design of driven operation of disconnectors and main switches, mechanical interlock device is also considered. The device is operated with easy structure and reliable action.Working Environment:
