YBD1-12 Buried Box-type Substation
With the acceleration of the process of urban and rural modernization, the construction of the city has entered the stage of urban beauty aimed at improving the appearance of the street. The traditional box-type substations are disorderly and occupy the golden ground of the downtown area, which is incompatible with the beautiful urban environment. The construction of urban planning, highways, and public facilities has higher and higher requirements for power equipment. In developed countries such as Europe, the United States, and Japan, transformers have been gradually buried underground in accordance with the concept of urban ecological design.
Buried box transformer is to meet the requirements of the above areas and design and development of a new power equipment. Buried box transformer is mainly composed of buried transformer and outdoor switch equipment of advertising light box type. Buried transformer is a new type of compact substation equipment, which is composed of transformer, high voltage load switch, fuse and so on. It is installed in the pit, does not occupy the floor space, and can run in water for a period of time. The outdoor switchgear of advertising light box is a mixed structure integrating billboard and outdoor switchgear, and is installed on the ground. The inside of the box is an outdoor high and low voltage power distribution cabinet, and both sides are advertising light boxes, which have excellent visual effects.
The buried box transformer conforms to the urban ecological design concept, covers an area of small, beautifies the environment, and is suitable for urban traffic trunk roads, residential quarters, airports, stations, highways and other places. Will become the transformation trend of urban distribution network equipment.

1. high reliability
The enclosure of the buried transformer used in the buried transformer is made of anti-corrosion stainless steel, and the high and low voltage inlet and outlet lines are waterproof, fully sealed, fully insulated and fully shielded. It ensures the anti-corrosion and sealing ability of the buried transformer, and the overall protection level reaches IP68, which can be submerged in water.
High-voltage configuration plug-in type and backup fuse, in the event of transformer failure, can be quickly cut off, does not affect the overall line.
Waterproofing and drainage are considered in the design and manufacture of transformer pit foundation. The top ventilation hole has effective rainproof and waterproof function. The side and bottom are treated with special waterproof materials. Water seepage cannot invade. Submersible pump controlled by automatic drainage system is installed at the bottom.
The buried box transformer can be submerged in water and can resist flood disasters. All measures ensure the service life of the buried transformer for 20 years, which can be maintenance-free and maintenance-free, and effectively improve the reliability of the power supply system.2. energy saving and consumption reduction
Energy saving and consumption reduction have become the consensus of the whole society. The buried transformer selected for buried box transformer is a low-loss product. The buried transformer loss of silicon steel core reaches S11 series. Compared with ordinary transformers, the no-load loss is 30% lower and the load loss is 15% lower. The loss of buried transformer with amorphous alloy core is greatly reduced, and its no-load loss is reduced by 80%.3. noise reduction
As we all know, the most important factor affecting the surrounding residents of the box-type substation can be said to be the noise of the transformer. The noise source of the transformer mainly comes from the iron core. The height of the transformer installed in the ordinary box transformer is generally about 1.2m from the ground. If the box transformer is installed near the residential window, the noise will inevitably be introduced into the residential room in the dead of night, affecting people's sleep. Once the transformer is installed underground, its noise can be significantly reduced, with little impact on residents.4. and beautiful, in harmony with the environment
The general box substation covers a large area and is difficult to coordinate well with the environment. Especially in some high-end living quarters, the power distribution facilities or box-type substations in the quarters cannot be coordinated with the community environment, which affects the overall beauty of the community and even affects the price of nearby buildings.
The buried box transformer because the transformer is installed underground, does not affect the surrounding environment, the distribution box installed on the ground is small, it is easy to coordinate with the surrounding environment. For example, in a living area, the ground distribution box can be matched with the greening of the area and become a part of the landscape of the area. For example, in urban trunk roads and highways, the distribution box on the ground can be designed as an advertising light box.5. create value for customers
Buried box transformer covers an area of small, in the living area, can replace the traditional power distribution room to reduce the construction of power distribution room, the investment benefit is very obvious.
The underground box transformer is beautiful in shape and coordinated with the surrounding environment. It is installed in the living area, which not only does not affect the price of the surrounding real estate, but also can improve the grade of the community.
The buried box-type substation installed on the city's main roads and expressways, and the advertising light box-type switching equipment on the ground, will bring long-term advertising revenue to customers. -
