Assembling-type transformer substation whole structure

Abstract

The invention discloses an assembling-type transformer substation whole structure. The assembling-type transformer substation whole structure comprises a box, steel vertical columns, a steel platformand cable bridge frames; and the box is arranged on the steel vertical columns, the cable bridge frames are arranged on the lower portion of the box, and the steel platform is arranged around the box.The cable bridge frames are mainly used for laying cables at the bottom of a transformer substation, the structure is simple, and the space is saved; through a supercharging device, the indoor air pressure of the transformer substation is greater than the external atmosphere pressure, and as for the situation that people go in and out of the box-type transformer substation in a short time, sand wind can be effectively prevented from entering the box; the temperature in the transformer substation can be kept in the constant range through an air conditioner, and the safety of working of electrical equipment in the transformer substation is improved; a sand blocking device can prevent the sand wind from entering the air conditioner, and the service life of the air conditioner is prolonged; and a frame in the lower portion of the air conditioner is of a hollowed-out structure, and the situation that accumulated water in the lower portion of the air conditioner enters the air conditioner,and the internal line of the air conditioner is damaged is prevented.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a complete machine structure of an assembled substation. Background technique [0002] Box-type substation, also known as prefabricated substation or prefabricated substation, is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device, which are prefabricated indoor and outdoor compact in a factory according to a certain wiring scheme. Power distribution equipment is to organically combine functions such as high-voltage power receiving, transformer step-down, and low-voltage power distribution, and install a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, and movable Inside the steel structure box, mechanical and electrical integration, fully enclosed operation, especially suitable for urban network construction and transformation, is a brand-new substa...

Problems solved by technology

[0004] After the current substation works for a long time, the box will generate a lot of heat, which will cause the temperature inside the box to rise. The general heat dissipation method is to dissipate heat through the vent holes or louvers on the outer wall of the box. When the external temperature is very high, the air flow in the box is very weak, and the temperature inside and outside the box is very high, and the heat dissipation effect is extremely bad. The large amount of heat generated by the components in the substation is easy to cause the substation In the event of a power outage, an explosion may occur in severe cases

Moreover, the surrounding environmental conditions of industrial and mining enterprises are mostly very harsh. Once the door of the outdoor box-type substation is opened, sand and dust can easily enter the substation, bringing safety hazards to the internal electrical equipment; on the other hand, because the air conditioning system works 24 hours a day, Reduced service life of the air conditioning system

[0005] Both the outdoor box-type substation and the outdoor steel structure house adopt a frame structure, that is, the steel structure house is assembled from a base, a frame, an outer wall panel, an inner wall panel, a ceiling, and a roof panel. Due to the existence of the frame, the wall panel and Some splicing parts of the frame must be sealed by sealant, or spliced ​​by full welding. If the sealant is not applied properly or there are defects such as welding, it will cause poor sealing and prone to water leakage, thus jeopardizing the Operation safety of equipment in box-type substation
