[0002] Box-type substation, also called prefabricated substation or prefabricated substation. It is a kind of factory prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme and includes high-voltage switchgear, distribution transformer and low-voltage distribution device. Prefabricated substation is used in urban high-rise buildings, urban and rural buildings, residential areas, high-tech development zones, small and medium-sized factories, mines and oil fields, and temporary construction power supply. It is used to receive and distribute electric energy in the distribution system. It has the characteristics of strong completeness, small size, compact structure, safe and reliable operation, convenient maintenance, and portability.

[0003] Compared with traditional substations, the installation process of prefabricated substations is relatively simple, but there are also some problems.

Some larger equipment cannot be installed inside the prefabricated substation, and it is impossible to achieve a combination of multiple substations. The design ignores the scalability of the product (that is, the ability to add some new additional equipment on the basis of the substation). Therefore, the applicant has made a beneficial design and found a solution to the above problems. The technical solution to be introduced below was produced in this context. Summary of the invention

[0045] The use principle of the utility model is now described as follows:

[0046] Example 1

[0047] When the first base 1 needs to be connected and fixed with the second base 2, the fixing plate 71 is pulled upward by the handle 74, so that the spring 72 is subjected to force and stored energy, and the second base 2 is moved, so that the extension plate 21 is inserted into the fixing groove 11, and the extension plate 21 abuts the end face of the fixing groove 11, thereby ensuring that the second protrusion 713 can accurately enter the first protrusion 22, and the handle 74 is released. The spring 72 releases the elastic force, so that the second protrusion 713 is embedded between the first protrusions 22, the fixing plate 71 abuts the anti-slip block 23, and the anti-slip block 23 abuts the side of the first protrusion 22, thereby forming a clamping force and a mutual interlocking force, ensuring that the module connection between the first base 1 and the second base 2 is stable and secure.

[0048] Example 2

[0049] When the first base 1 is connected and fixed with the second base 2, in order to expand the internal space and thus remove the side panel 5, in order to prevent rainwater from entering the internal space of the substation through the gap between the cover plates 6, the second latch block 621 is inserted into the second through hole 611, so that the first cover plate 61 and the second cover plate 62 are interlocked and connected with each other, thereby improving the sealing of the connection between the first cover plate 61 and the second cover plate 62, and then, it is lifted by the lifting ring 63 and fixed to the side panel 5, the door frame plate 4, and the support plate 3 by fasteners such as screws and bolts.
