When it comes to substations, everyone's first reaction may be the steel reinforced structure, coupled with interwoven overhead lines. In fact, this is only the most common type of substation, with a professional name of "outdoor substation", which corresponds to indoor and semi indoor substations. Today we will learn about their differences.
Outdoor substation refers to a substation where the main equipment is mostly arranged outdoors. It is characterized by large floor area, electrical devices and buildings can fully meet various distance requirements, such as electrical safety clearance, fire separation, etc., heat dissipation is also very convenient, cost investment is low, and operation, maintenance and overhaul are very convenient. Substations with higher voltage levels are generally arranged outdoors, taking into account their advantages of economy, convenience, stability, and reliability.
Indoor substation refers to a substation where the main equipment is placed indoors. It reduces the total floor area, but has higher requirements for the internal layout of the building. It has the characteristics of compactness, large height difference, and varying requirements for floor height. Sometimes, it also needs to be specially beautified according to the surrounding environment, suitable for densely populated urban areas. At present, most of the newly built 110 kV substations in the main urban area adopt user internal layout.
A semi indoor substation refers to a production complex where all distribution devices, except for the main transformer, are centrally arranged. Not only does it combine the advantages of indoor substations in saving land area and coordinating with the environment for aesthetics, but the cost is also relatively low. Suitable for construction in economically developed small towns.
Indoor and semi indoor substations, due to their highly integrated layout and the arrangement of live equipment within a building, have significantly lower electromagnetic and noise impacts on the surrounding environment compared to outdoor substations. But please rest assured that no matter what form the substation adopts, it is an optimized choice tailored to local conditions. It is necessary to provide continuous and stable electricity to the surrounding users, while also ensuring that the surrounding environment meets national standards and never produces excessive environmental impacts.
