Urban underground modular substation

Abstract

The present invention relates to the technical field of electrical equipment, in particular to an urban underground modular substation, including electrical equipment and a casing for containing the electrical equipment. The casing includes two side plates and several bottom walls connected inside the side plates, The splicing plate body and locking plate body of the side wall and the top wall are provided with a gap on the top wall formed by the splicing plate body and the locking plate body; the main body is spliced ​​by the side plate body, the scattered splicing plate body and the locking plate body As a result, the entire shell does not require the hoisting of large equipment during transportation and handling, and can be assembled in the case of limited space or space, so it can be adapted to more occasions, and only a small amount of equipment is required in the assembly process. The bolt fixing parts are fixed, and the splicing panels are connected by the locking parts that are inflated and locked after splicing, which increases the convenience of assembly and the sealing of the splicing shell, and also has good heat insulation and moisture resistance.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to an urban underground modular substation. Background technique [0002] With the rapid development of my country's economy, the construction of power grids is also rapidly advancing. Urban load centers have high land acquisition costs, limited planning land, and high environmental protection requirements. Electricity has become an indispensable energy source for urban life, and power supply is one of the lifelines to ensure urban operation. In recent years, with the rapid development of urban construction and the continuous improvement of living standards, the urban electricity load has shown a momentum of continuous and rapid growth. As we all know, the electricity load center often coincides with the core of urban construction. For some large cities, the commercial planning of the core area is very compact, and it is increasingly difficult to select the location of la...

AI Technical Summary

Problems solved by technology

[0004] 1. The equipment in the box does not have the conditions for underground operation, and the protection and equipment operating environment cannot be satisfied;

[0005] 2. It is impossible to carry out equipment maintenance in the box, and there is a large demand for equipment operation and operation space;

[0006] 3. It can only be installed on the ground. It is necessary to set up fences and keep a safe distance around the equipment installation, which will have different degrees of impact on the surrounding environment. The low degree of automation cannot realize the remote monitoring function

[0008] Since the underground substation is placed underground, the internal electrical equipment needs a protective shell room, and this shell room usually needs to be hoisted and transported as a whole, so it is necessary to set up a special hoisting space and hoisting channel for the equipment, and some construction sites may be due to limited space. Larger hoisting equipment cannot be used, so a modular spliced ​​substation is urgently needed
