What is a box-type substation/ compact substation?

Box-type substations also called prefabricated substations . It is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory-prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme. It combines the functions of transformer step-down and low-voltage power distribution organically. At the same time, it is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, and movable steel structure box. It is especially suitable for urban network construction and transformation. It is a rising one after civil construction substations. A brand new substation. The box-type substation is suitable for mines, factories and enterprises, oil and gas fields and wind power stations. It replaces the original civil power distribution rooms and power distribution stations and becomes a new type of complete power distribution device.

Principle of box-type substation

Box-type substation is a compact complete set of power distribution equipment 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. 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.
