[0025] Working principle: The power cabinet is easy to assemble. When in use, first assemble the base 1 and the support base 2, and then install a corresponding number of unit shells 8 in series on the base 1 according to the number of power equipment to be installed. When installing the unit shell 8, first insert the docking clamping plug-in plate at the rear end of the unit shell 8 into the docking clamping sleeve 14, then insert the limit plug rod 19 into the middle limit docking sleeve 15 and the bottom limit docking sleeve 5, and then insert the middle connecting plate 13 between the adjacent unit shells 8, so that the limit clamping protrusion 26 on the middle connecting plate 13 can effectively clamp the docking protrusion 27 so that the adjacent unit shells 8 The unit housing 8 can form a whole, and then according to the need for heat dissipation, the corresponding liquid cooling circulation pipe 12 corresponding to the liquid cooling circulation interface pipe 10 is installed inside each unit housing 8, and the inner mounting frame 11 is fixed by bolts at the position where the power control device needs to be installed in each unit housing 8, and then the top of the unit housing 8 at the top is sealed and fixed by the top closing plate 20. At this time, the required assembled power cabinet can be formed, and then the required power control equipment is installed on the inner mounting frame 11 and the instrument is installed on the instrument mounting frame 21, and then the cable is correctly connected to the cabinet through the rear terminal block 24. During the use of the device, the inside of the cabinet can first be naturally cooled by air through the plug-in dustproof net 9. The plug-in dustproof net 9 itself is easy to disassemble and clean and maintain. Then, the external fan can be connected through the air cooling pipe 17 to perform active air cooling and heat dissipation, and the external liquid cooling circulation device can be connected through the liquid cooling circulation interface pipe 10 to perform liquid cooling and heat dissipation on specific areas inside the cabinet. Since the device can be freely assembled to form power cabinets of different heights, it is suitable for use in areas of different spatial heights. At the same time, since the internal mounting frame 11 and the liquid cooling circulation pipe 12 in each unit shell 8 can be removed separately, the internal mounting frame 11 and the liquid cooling circulation pipe 12 can be removed in some unit shells 8 to use as idle space for maintaining other equipment, thereby improving the maintainability of the equipment. Similarly, power control equipment for collaboratively realizing the same power control function can also be installed in different unit shells 8. In this way, when the assembly position of the power control system is readjusted, the above-mentioned equipment can be removed together with the corresponding unit shell 8 and reassembled into a new power cabinet, thereby improving the convenience of position adjustment of the power control system, and therefore has high practical value.
