Urban underground modular substation

Abstract

The invention relates to the technical field of power equipment, in particular to an urban underground modular substation, which comprises electrical equipment and a shell for accommodating the electrical equipment, wherein the shell comprises two side plate bodies, a plurality of splicing plate bodies and locking plate bodies which are connected to the inner sides of the side plate bodies to form a bottom wall, side walls and a top wall, a notch is formed in the top wall formed by the splicing plate bodies and the locking plate bodies; and a main body is formed by splicing and combining the side plate bodies, the scattered splicing plate bodies and the locking plate bodies. Therefore, the whole shell does not need to be hoisted by large-scale equipment in the transportation and carrying processes, and can be assembled under the condition that the space or the field is limited, the shell can adapt to more occasions, only a small number of bolt fixing pieces are needed for fixing in the assembling process, the splicing plate bodies are connected through the locking parts which are locked through inflation after splicing, the assembling convenience and the sealing performance of the splicing shell are improved, and meanwhile the good heat insulation and moisture prevention capacity is achieved.

Description

Technical field[0001]The present invention relates to the technical field of power equipment, in particular, urban underground modular substation.Background technique[0002]With the rapid development of my country's economy, the construction of power grid is also rapidly promoted. The city load center is high, the planning is limited, and the environmental protection requirements are high. Electricity has become an indispensable energy in urban life, and power supply is one of the lifesies of the city's operation. In recent years, urban construction has developed rapidly, and the living standards have been continuously improved. It is well known that the electricity load center is often combined with the core of urban construction. For some big cities, the business plan is very compact, and the selection difficulty of independently constructing large-scale substations is increasing. Building a large underground substation is the main direction of the future.[0003]At present, the city...

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
