[0002] The new modular high-voltage switchgear, as an innovative product in the power system, has become a new favorite in my country's power grid construction due to its unique design concept and technological advantages. It modularizes and integrates the components of the traditional high-voltage switchgear, achieving an integrated and compact design through optimized combination. The new modular high-voltage switchgear adopts advanced production processes and materials, and features reasonable structure, convenient installation, and easy transportation. It has become a model for the transformation and upgrading of the power industry, injecting new vitality into the development of my country's power industry.

[0003] According to Chinese Utility Model Publication No. CN220475172U, a combined high-voltage switchgear is disclosed. This utility model allows the top and bottom cabinets to be connected through the combination of insertion holes and insertion rods, enabling the two docking seats to contact each other. With the help of a sealing gasket, the device can be sealed. At the same time, the insertion plate can be inserted into the interior of the U-shaped plate. The insertion plate is connected to the U-shaped plate by the threaded connection of the threaded rod and threaded hole, positioning the top cabinet and thus enabling rapid assembly of the top and bottom cabinets. The rain cover can cover the docking seats on both sides, thereby keeping rainwater away from the connection point and preventing rainwater from entering the equipment. This solves the problems of not only having a large structure that reduces assembly efficiency, but also the lack of a water-blocking mechanism during use, which makes it easy for rainwater to seep in.

[0004] However, there are some issues to consider when implementing the above technical solutions: Although the high-voltage switchgear adopts an assembly structure, its bottom cabinet and top cabinet cannot be disassembled and folded during transportation, which still occupies a large amount of space, resulting in reduced transportation efficiency and increased logistics costs.
