Description

Technical Field

[0001] The present invention relates to the field of substations, and particularly to a box-type substation. Background Art

[0002] A box-type substation, also known as a prefabricated substation or prefabricated transformer substation, is a high-voltage switchgear, a distribution transformer, and a low-voltage distribution device. It is a factory prefabricated indoor and outdoor compact distribution equipment arranged according to a certain wiring scheme, that is, functions such as transformer step-down and low-voltage power distribution are organically combined together and installed in a moisture-proof, rust-proof, dust-proof, mouse-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, movable steel structure box. It is especially suitable for urban network construction and transformation and is a brand-new substation that emerged after the civil 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 room and substation and becomes a new type of complete set of power transformation and distribution devices. A box-type substation (abbreviation: box substation) is a compact complete set of distribution devices that combines high-voltage switchgear, distribution transformers, low-voltage switchgear, electric energy metering devices, and reactive power compensation devices, etc. according to a certain wiring scheme. It is applicable to a three-phase AC system with a rated voltage of 10 / 0.4 KV and is used for power transmission and distribution. Compared with the European box substation of the same capacity, the structure of the American box substation is more reasonable. Since the European box substation installs the transformer and ordinary high-voltage electrical equipment in the same metal shell box body, the temperature of the transformer room is very high, which causes difficult heat dissipation and affects the output; it is easy to catch fire inside. In a conventional substation box, a fire extinguisher is not installed inside. If the fire extinguisher is placed outside, it is also easy to be damaged. Summary of the Invention

[0003] The purpose of the present invention is to provide a box-type substation to solve the problem that it is easy to catch fire inside the substation box in the above background art. In a conventional substation box, a fire extinguisher is not installed inside. If the fire extinguisher is placed outside, it is also easy to be damaged.
