Description

Technical Field

[0001] The present invention relates to the technical field of box-type substations, and in particular to a 10KV prefabricated box-type substation that is easy to maintain. Background Art

[0002] A box-type substation, also known as a prefabricated substation or prefabricated substation, is a factory-fabricated, compact indoor and outdoor power distribution system that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution equipment according to a specific wiring scheme. It organically combines the functions of transformer step-down and low-voltage power distribution within a fully enclosed, removable steel structure that is moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, and heat-insulated. It is particularly suitable for urban power grid construction and renovation, and represents a new type of substation that has emerged after the civil substation. Box-type substations are suitable for mines, factories, enterprises, oil and gas fields, and wind power stations. They replace existing civil power distribution rooms and substations, becoming a new type of complete power transformation and distribution system.

[0003] In the existing 10KV prefabricated box-type substation, the independently arranged wiring room, high-voltage room, low-voltage room and transformer room are generally fixed on the back panel inside the substation box. When the back panel is squeezed, it is easy to cause damage to the wiring room, high-voltage room, low-voltage room and transformer room. Secondly, the wiring room, high-voltage room, low-voltage room and transformer room are located on the back panel inside the substation box. Due to the limited internal space of the substation box, their maintenance is more troublesome, so it cannot meet the needs of users. Summary of the Invention

[0004] The purpose of the present invention is to provide a 10KV prefabricated box-type substation that is easy to maintain. The substation box is independently equipped with a wiring room, a high-voltage room, a low-voltage room and a transformer room. The wiring room is fixed on a first screw-nut seat, and the high-voltage room, the low-voltage room and the transformer room are fixed on a second screw-nut seat. Such an independent suspended arrangement overcomes the traditional method of fixing the high-voltage room, the low-voltage room and the transformer on the back plate of the substation box, which is prone to deformation and damage due to collision. By further rotating the first screw and the second screw, the first screw-nut seat and the second screw-nut seat are driven to move, and the position of the wiring room, the high-voltage room, the low-voltage room and the transformer room can be adjusted. When it is convenient for maintenance, the wiring room, the high-voltage room, the low-voltage room and the transformer room can be adjusted to the opening of the substation box, which is convenient for maintenance.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: a 10KV prefabricated box-type substation that is easy to maintain, comprising a substation box body, a wiring room is provided inside the substation box body, and a high-voltage room, a low-voltage room and a transformer room are provided inside the substation box body above the wiring room;

[0006] A first strip-shaped groove is formed on the bottom plate of the transformer substation box, and a first lead screw is rotatably connected in the first strip-shaped groove. A first lead screw nut seat is rotatably connected to the first lead screw in the first strip-shaped groove, and the first lead screw nut seat is fixed to the bottom plate of the wiring room with bolts;
