Large flat-top box-type transformer station housing structure

Abstract

The invention discloses a large flat-top box-type transformer station housing structure comprising an over-ground cabinet body and a underground structure. The over-ground cabinet body is composed of a box top, a high-voltage chamber, a high-voltage chamber door, a low-voltage chamber, a low-voltage chamber door, a side-by-side door between the high-voltage chamber and the low-voltage chamber, and a base plate. The underground structure a concrete base surrounding the underground transformer station housing, and a basal surface arranged on the lower end of the concrete base. A filler layer is arranged on the lower layer of the box top. The high-voltage chamber door and the low-voltage chamber door are arranged on both sides, namely the side surface of the high-voltage chamber and the side surface of the low-voltage chamber, of the over-ground cabinet body. The door of the high-voltage chamber, the door of the low-voltage chamber, and the door of a transformer chamber are separate so as to operate independently and not to interfere with others. Thus, the overall heat-dissipating effect of a transformer station is achieved, the influence of hot natural environment is reduced, the door of a chamber required to be overhauled is opened so that good pertinence and safe operation are achieved.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, and more specifically relates to a large flat-top box-type substation shell structure. Background technique [0002] At present, prefabricated box-type substations are generally suitable for 10KV ring network power supply, dual power supply or transformer terminal power supply system, as receiving and distributing power control equipment, suitable for urban public power distribution, high-rise buildings and residential quarters, industrial and mining enterprises, Ports, roads, and construction sites usually have the characteristics of compact structure, small footprint, and safe and reliable operation. [0003] At present, the existing box-type substations are generally heavy and unattractive in appearance, and the heat dissipation conditions of the box-type substation often cannot meet the heat dissipation requirements of transformers and other power devices. At present, the...

Problems solved by technology

[0003] At present, the existing box-type substations are generally heavy and unattractive in appearance, and the heat dissipation conditions of box-type substations often cannot meet the heat dissipation requirements of transformers and other power devices.

At present, the prefabricated shell of the box-type substation is made into a house shape. When such a roof structure is provided with a filler layer that absorbs sunlight on the lower layer of the shell, it is difficult to achieve uniformity, so how to match the filler layer with the roof structure is a problem

And most of the current mobile box-type substations set the high-voltage room door and the low-voltage room door together. When the overall structure of the device is small, such a setting can effectively use the limited space, but this design is directly transplanted to large-scale substations. When the box-type substation is installed, it will require a lot of space to assemble the gate
