The column 2 is composed of a number of pillars 21, and each adjacent two pillars 21 are plug-in fixed. The pillar 21 at the top of the column 2 is made of metal, and the other pillars 21 are made of PPS. The reason why the top pillar 21 is made of metal is that the two upper layers are at the same potential, and the reason why the other pillars 21 are made of PPS is that the material can be injection molded, and the hardness and strength after molding are very high, and the insulation performance is also good. The material of the top pillar 21 and the top cover 3 is aluminum alloy, and the material of the base 1 is SUS304 stainless steel. A limiting fastening device is formed between the top cover 3 and the base 1 to prevent the entire component from shifting and shaking. The pillar 21 is formed by injection molding, and the integrated production avoids errors, which is convenient for the efficiency and convenience of automated assembly line assembly;

[0025] The top of the pillar 21 is provided with a plurality of plug holes 22, and the bottom of the pillar 21 is provided with a plurality of plug posts 23 used in conjunction with the plug holes 22. The top surface of the pillar 21 located at the top of the pillar 2 is provided with two first fixing holes 31, and the top of the top cover 3 is provided with a plurality of second fixing holes 32 used in conjunction with the first fixing holes 31, and bolts used in conjunction with the first fixing holes 31 are screwed into the plurality of second fixing holes 32; a card slot 7 is formed between each two adjacent pillars 21, and the card slot 7 is composed of a first fixing slot 71 and a second fixing slot 72 provided on one side of the pillar 21 , the first pressure-equalizing ring 4 and the second pressure-equalizing ring 5 are both fixed in the card slot 7 by snap-fitting; a card slot 7 is formed between each two adjacent pillars 21, and the card slot 7 is composed of a first fixing groove 71 and a second fixing groove 72 opened on one side of the pillar 21, and the first pressure-equalizing ring 4 and the second pressure-equalizing ring 5 are both fixed in the card slot 7 by snap-fitting, and a positioning hole 24 used in conjunction with the plug-in column 23 is opened on the top of the base 1, and the plug-in column 23 is inserted into the positioning hole 24 and fixedly connected by a sealant; the base 1 and the top cover 3 are both annular structures, and a plurality of columns 2 are annularly arranged between the base 1 and the top cover 3;

[0026] When the high-voltage rectifier bracket needs to be disassembled during use, the bolts can be screwed out from the first fixing holes 31 and the second fixing holes 32. When all the bolts are screwed out from the first fixing holes 31 and the second fixing holes 32, the top cover 3 can be directly removed from above the multiple columns 2. Since each adjacent two pillars 21 are plug-in fixed, multiple first equalizing rings 4 and multiple second equalizing rings 5 ​​are all clamped in the clamping grooves 7, so that the pillars 21, the first equalizing rings 4 and the second equalizing rings 5 ​​can be disassembled from top to bottom in turn.
