Product structure characteristics

1The basic structure of the box transformer is divided into "eye" shape and "product" shape. The box frame is welded with high-quality channel steel and angle steel, which has high mechanical strength. The box is made of aluminum alloy profile, which has good anti-corrosion ability. The overall beautiful appearance can be coordinated with the surrounding environment through painting and coloring. The carefully designed lifting device provides great convenience for installation, transportation and movement.

2There are independent high-voltage room, transformer room and low-voltage room in the box transformer, the lighting of each room is automatically turned on with the opening of the door, and the high-voltage ring network switchgear can be selected as the compressed air type according to the user's needs./Vacuum type load onoff, and has"Five" function,When the current-limiting high-voltage fuse is used, when a certain fuse is blown, the load switch is automatically opened to avoid the failure caused by the lack of phase operation.

3The transformer room adopts self-disturbing ventilation and automatic control forced heat dissipation air cooling device, and has an exhaust system automatically controlled with temperature change, which can effectively control and reduce the temperature in the box and meet the operation requirements. According to user requirements, anti-condensation devices can also be used. According to user requirements, it can easily enter and exit from both sides of the transformer room through the gate along the track. The box material can prevent rain and dirt from entering, has long-term outdoor use conditions, ensures anti-corrosion, waterproof, dustproof performance, long service life, simple maintenance, and beautiful appearance.

42. The transformer can be dry-type or oil-immersed transformer, and oil-immersed transformer can be fully sealed with oil conservator or without oil conservator.

5The low-voltage chamber has the overall function of low-voltage switchgear for users to choose and combine arbitrarily.

6Shell material: shell materials are composite plate, stainless steel composite plate, aluminum zinc plate, stainless steel plate, metal carving plate.

72. Structural features: the high-pressure group is reasonable and compact,OptionalSF6,FZN57,VHCRing main cabinet, fullThe department has five anti-interlock functions.

8Natural ventilation and automatic ventilation cooling system of transformer can be applied to dry type and oil immersed transformer.

9Low-voltage room: according to the user needs to use a variety of structural power distribution scheme, power distribution, lighting distribution, reactive power automatic compensation, energy metering and other functions, equipped with automatic lighting system.
