[0002] The Chinese-style box-type substation is an ideal product for photovoltaic and wind power new energy power generation projects. The Chinese-style box-type substation is mainly composed of a low-voltage chamber, a high-voltage chamber and an external transformer.

[0003] In order to meet the needs of rapid installation during on-site installation, the Chinese-style box-type substation group is generally pre-assembled into two parts in the factory, namely the box structure consisting of the low-voltage chamber and the high-voltage chamber, and the transformer structure consisting of the transformer and its base. The box structure is usually customized according to different installation needs. Therefore, such a structure is not only large in size and not very convenient for transportation, but also very inconvenient for the later need to expand the box space. Therefore, we proposed a modular Chinese-style box-type substation to solve the above problems. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] See also Figure 1-Figure 4 A modular Chinese box-type substation includes a plurality of modular boxes 1 and transformers 2. The plurality of modular boxes 1 have the same structure. The modular box 1 includes a box base 101. A top plate 102 is arranged on the top of the box base 101. The four corners of the top of the box base 101 and the four corners of the bottom of the top plate 102 are fixedly installed by corner columns 103. A set of corner columns 103 located on both sides of the box base 101 are rotatably connected with a box door 104 through hinges. A partition 105 is fixedly installed between the box base 101 and the top plate 102 through a plurality of middle columns, and the interior of the modular box 1 is divided into a low-voltage chamber 106 and a high-voltage chamber 107 by the partition 105. A transformer base 3 is fixedly installed at the bottom of the transformer 2, a side wall plate 1 4 is fixedly installed on the side of the modular box 1 close to the transformer 2, and a cable opening 401 is opened on the side wall plate 1 4, and a side wall plate 2 5 is fixedly installed on one side of the modular box 1 away from the transformer 2;

[0029] Ear pieces 108 are fixedly welded on the sides of the corner columns 103 and the sides of the box base 101, and two adjacent modular boxes 1 are detachably connected through corresponding ear pieces 108 and bolts 1; ear pieces 2 301 are fixedly welded on both sides of the transformer base 3, and ear piece 2 301 and corresponding ear piece 108 are detachably connected through bolts 2.

[0030] The assembly process of this modular Chinese box-type substation is as follows:

[0031] First, several modular boxes 1 prefabricated and assembled in the factory are transported to the installation site, then arranged in sequence, and connected by ear pieces 108 and bolts 1 between adjacent modular boxes 1 to form a complete box structure, and finally side wall panels 1 4 and 5 are installed on both sides of the assembled box structure to seal both ends of the box structure, and then the transformer 2 is transported to the installation site together with the installed transformer base 3, and the ear piece 2 301 and the corresponding ear piece 108 are connected by bolts 2.
