Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated substation design, in particular to a prefabricated substation structure. Background Art

[0002] Substations are important facilities in the power system, used to convert the electric energy of high-voltage transmission lines into low-voltage power supply to users. It is mainly composed of transformers, switchgear and protection equipment. The transformer in the substation can convert high voltage (usually 110 kV or 220 kV) into low voltage (commonly 10 kV, 0.4 kV, etc.) to supply users in close proximity. Substations can also reasonably adjust and distribute electric energy according to the load demand of the power grid to ensure the stable operation of the power grid. Substations are equipped with various protection devices and safety measures to prevent power system failures and disasters and protect the safety of personnel and equipment.

[0003] The construction of existing substations takes a long time, and in places where every second counts, such as construction sites, substations need to be built as soon as possible to facilitate the operation of subsequent large-scale equipment. Therefore, a prefabricated substation structure is needed to facilitate the efficient construction of substations, while solving the heat dissipation problem caused by long-term operation of substations and the dehumidification problem of substation components in humid areas, thereby increasing the scope of application of the device.
