YBD-12/0.4 Outdoor box-type substation is a high-voltage switchgear, distribution transformer and low-voltage power distribution device, which are prefabricated indoor and outdoor compact power distribution equipment in a factory according to a certain wiring scheme. At the same time, it is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully-enclosed, movable steel structure box, especially suitable for urban network construction and reconstruction. A brand new substation. Box-type substations are suitable for mines, factories, oil and gas fields and wind power stations.

The basic structure of YBD-12/0.4 Outdoor box-type substationis divided into "me" shape and "pin" shape. The frame of the box body is welded with high-quality channel steel and angle steel, which has high mechanical strength. The box body is made of aluminum alloy profiles, which has good anti-corrosion properties. The overall beautiful appearance can be coordinated with the surrounding environment after painting and coloring, and the well-designed bottom lifting device provides great convenience for installation, transportation and movement.

There 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. The high-voltage room is equipped with high-ring network switchgear, which can be selected according to the user's needs. Compressor type, vacuum type load switch, and has the "five-proof" function. When the current-limiting high-voltage fuse is used, a certain phase fuse is blown. Automatic opening of the load when the load is closed, avoiding the failure caused by the lack of phase operation

The transformer room adopts natural ventilation and automatic control forced cooling air cooling device. It has an exhaust system that is automatically controlled with temperature changes. It can effectively control and reduce the temperature in the box. It can meet the operating requirements. Device. According to the user's requirements, it can be easily entered and exited from the gate from both sides of the transformer room along the track. The box material can prevent rainwater and dirt from entering. It has the conditions for long-term outdoor use, ensuring anti-corrosion, waterproof, dust-proof performance, long service life, simple maintenance and beautiful appearance.

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

The low-voltage room has the overall function of low-voltage switchgear, which can be selected by users and combined arbitrarily.
