Of course, in other embodiments, the front half bulkhead and the rear half bulkhead can be disposed at the left end of the cabin body of the two high-pressure cabin modules, in which case the right end of the cabin body of the two low-pressure cabin modules is an open structure, and the vertical bulkhead of the cabin body of the low-pressure cabin module is L-shaped, that is, the partition wall is completely formed by the corresponding bulkhead on the two high-pressure cabin modules.

In the above three embodiments, the switch cabinets in the high-voltage switch module have the same shape, and of course, in other embodiments, the switch cabinets in the high-voltage switch module may also adopt other types of switch cabinets, so that the splicing and assembling of the equipment modules are satisfied. And, concrete cubical switchboard type and quantity in the high-voltage switch module also can be selected according to actual need to satisfy the operation requirement and be the standard.

The modularized square cabin type switch station provided by the invention is formed by splicing four cabin modules, each cabin module is an independent module, but the cabin of each cabin module is not in a fully-enclosed structure, and the whole switch station structure can be formed only by splicing the cabin modules with other three cabin modules. When transporting each independent module, the space that every independent module occupy only is the quarter of whole switchyard, even if for the complete primary cabin body and the secondary cabin body of transportation among the prior art, it has also only occupied half, can effectively reduce the transportation degree of difficulty like this, effectively enlarges the whole capacity and the volume of whole switchyard, satisfies the design, the equipment requirement of large capacity, bulky switchyard. And moreover, the modular design is adopted, the construction and debugging period of the switch station can be effectively shortened, and the method has a good popularization and application prospect.

Finally, although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments without departing from the inventive concept, or some of the technical features may be replaced with equivalents. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
