Use of box-type substation

The box-type substation is a compact complete set of power distribution devices that combines high-voltage switchgear distribution transformers, low-voltage switchgear, electric energy metering equipment and reactive power compensation devices in one or several boxes according to a certain wiring scheme. That is, the functions of high-voltage power receiving, transformer step-down, and low-voltage power distribution are organically combined and installed in a moisture-proof, rust-proof, dust-proof, rat-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, and movable steel structure box in vivo. It is suitable for use in a three-phase AC system with a rated voltage of 10/0.4KV, as a circuit and for distributing electric energy.

The main features of the box-type substation: The box-type substation covers a small area. The general box-type substation covers an area of only 5~6㎡, and it can even be reduced by 3~3.5㎡. It is suitable for places such as general load-intensive industrial and mining enterprises, ports and residential quarters. It can extend high-voltage power supply to the load center, reduce the radius of low-voltage power supply, and reduce losses. There are few low-voltage power supply lines, generally 4~6 lines. Shorten the on-site construction cycle and reduce investment. The appearance is novel and beautiful, which can be coordinated with the surrounding environment of the substation.
