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

 

Types of Box Type Substations
 

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.

FAQ

 

Q: What is a box type substation?

A: Box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage distribution device.

Q: What is the difference between a station and a substation?

A: The main difference we find between a transformer station and an electrical substation is the magnitude of the installations. While transformer stations are linked to high/medium-voltage transmission systems, electrical substations are designed to support and transform lower voltages.

Q: What is the purpose of a transformer box?

A: Also known as a residential transformer, it is a key piece of equipment in your home's power system. Usually connected to underground cables. It can step down the high voltage (7.2kV, 14.4kV, 12.47kV, 24.94kV) to the low voltage (120V, 240V) required by household electrical equipment.

Q: Are substations AC or DC?

A: A substation is a high-voltage (HV) electric system facility used to switch generating stations, transmission systems, distribution systems, and to step voltages up or down, with some substations transforming and converting power from alternating current (AC) to direct current (DC) or DC to AC, respectively.

Q: Why is 110v DC used in substations?

A: The main reason behind DC supply in substations is the continuous power supply in the control circuit. DC is a reliable source for current supply because we can get it from the battery. It will continuously supply electricity till it's not discharged. The battery can store electricity power.

Q: What are the three main parts of a substation?

A: An Electrical substation is a critical component in the electrical power distribution system, comprising three main parts: transformers, switchgear, and control systems. These parts work together to ensure efficient energy distribution, voltage regulation, and safety within the grid.
