Product Details

Box Type Substation Compact Transformer Substation For Power Transmission

 

 

Product Description

 

Box-type substations (also known as "box transformers") are generally composed of high-voltage compartments, transformer compartments, and low-voltage compartments. Box-type substations are a relatively simple type of power distribution equipment, and the choice of transformer capacity can be handled according to general principles, with a capacity generally not exceeding 1250kVA.

 

Applications

The first application is primarily in urban residential areas and streets during peak periods of high electricity demand. When the voltage needs to be increased, box-type substations can be used.
The second application is mainly for temporary power supply, such as on construction sites where existing buildings require electrical equipment upgrades. Box-type substations are also commonly used for outdoor operations, such as on construction sites, docks, airports, and other locations.

 

General Requirements

For simple lighting and public distribution, high-voltage metering is not required in the high-voltage connection scheme of the box-type substation, and only low-voltage metering or no metering is needed, and no compensation is required. The feeder circuit is 4-6 circuits, controlled and protected by plastic circuit breakers.
For power lighting and public distribution, the number of outgoing circuits from the box-type substation is increased to 8-12 circuits, and reactive power compensation is required.
For self-maintenance and special circumstances.

Material

 

1.The cabinet door adopts a double beveled edge process, which increases the structural strength of the same material by 50%.

 

2.The installation holes are all made using a multi-layer stamping and stretching process, which reduces the sliding wire situation by more than 80%.

 

3.The inlet and outlet holes adopt a composite structure of knockdown holes and square holes, which can be flexibly selected during on-site installation.

 

4.The box adopts a double folding process, which increases the structural strength of the same material by 50%.

 

5.The control circuit adopts a composite design of debugging mode and fire protection mode, greatly reducing the burning of fan and water pump equipment designed for fire protection during debugging.
