Advantages of Box Type Substation




Space saving
A significant advantage of container substation is their compact design. This type of substation is usually designed as one or more standardized boxes, which not only occupies a small area, but also can be flexibly laid out as needed.
Shorten the construction period
Since the prefabricated substation is a prefabricated modular structure, the construction process is greatly simplified. The prefabricated box completes most of the assembly work in the factory and then is transported to the site for rapid installation.
Improve safety
The enclosed design of the substation effectively isolates the electrical equipment from the outside world, reducing the risk of equipment being exposed to the environment.
Reduce environmental impact
Prefabricated compact substation are usually equipped with noise control devices and leak-proof devices to reduce the impact on the surrounding environment. Its enclosed structure effectively isolates the noise and odor inside the substation, thereby reducing interference with residents and the environment.
Reduce operating costs
Since the maintenance and management of substations are relatively simple, the operating costs are usually lower than those of traditional substations. Its compact design makes troubleshooting and equipment maintenance more convenient and quick.
Flexibility and adaptability
Compact substation have high flexibility and can be expanded and adjusted according to demand. This flexibility enables substations to adapt to different power load demands and changes, while traditional substations May require major structural changes when expanding and adjusting.
Applications of Box Type Substation
Industrial field
The industrial field is an important application field of box-type transformers. In industrial and mining enterprises, iron and steel, petrochemical, rail transit, metallurgy, aerospace and other industrial fields, box-type transformers as the core equipment for power conversion and distribution ensure the normal operation of production equipment.
New energy power generation
With the development of new energy, box-type transformers have also been widely used in the field of new energy power generation. Wind power generation, photovoltaic power generation and other new energy power generation methods have high requirements on the performance of transformers.
Transportation
In the field of transportation, box-type transformers also play an important role. Subway, railway stations, airports and other transportation facilities have a large and stable demand for power. And box-type transformers can provide stable and reliable power support for these facilities.
Specification Parameters of Box Type Substation
|
Cabinet |
The box shell is firm, heat-insulated and ventilated, stable in performance (corrosion-resistant, dust-proof, waterproof), and beautiful in appearance |
|
Functional units |
Divided into three independent areas: high-voltage room, low-voltage room, and transformer room. The high voltage room uses XGN15, HXGN17 and other SF6 switch cabinets. |
|
Busbar system |
Using three-phase four-wire system or three-phase five-wire system. High-quality three-phase tinned busbar copper bars with high mechanical strength and good heat dissipation. |
|
Voltage ratio |
0.69kV/11kV, 0.69kV/20kV, 0.69kV/33kV, 0.69kV/35kV |
Assembly type
Install the complete set of high and low voltage devices and transformers into metal boxes, and leave operating corridors in the high and low voltage distribution devices. This type of box transformer has a large volume and is rarely used nowadays.
Combination device type
Instead of using the existing complete set of devices, the high and low voltage control and protection electrical equipment are directly packed into the box, forming a whole. The design is considered maintenance free, with no operating corridors and a small box, also known as European style box transformers or ordinary box transformers.
One body type
Simplify the high-voltage control and protection devices, and put the high-voltage and low-voltage distribution devices and the main body of the transformer into the transformer oil tank together to form a whole, smaller, close to the oil immersed transformer of the same capacity, which is 1/3 of the European box type transformer.

Ambient temperature range: -45℃- +45℃. Outdoor wind speed: ≤35m/s. Relative humidity: daily average ≤95%, monthly average: ≤90%. Installation location: Installed in a place without fire, explosion hazard, severe pollution, chemical corrosion and severe vibration. If the above normal usage environment conditions are exceeded, customers can customize solutions with our company. The above is applicable to 50Hz, 10/35kV wind power generation system. The rated capacity of the transformer is 500~1600kVA.
