The invention relates to a box sealing structure of a column switch and a sealing ring. The box body sealing structure of the column switch comprises a box body and the sealing ring, wherein a mounting hole used for installing a wire outlet sleeve is formed in the box wall of the box body, an annular flange is arranged on the outer side wall of the box body around the mounting hole, a sealing ringgroove matched with the annular flange is formed in the sealing ring, and the two side groove walls of the sealing ring groove are in sealing fit with the radial sides of the annular flange. According to the box sealing structure of the column switch, more than two sealing surfaces are arranged between the sealing ring and the box body, the gas gap between the wire outlet sleeve and the box bodyis eliminated, the sealing performance of the wire outlet sleeve and the box body is greatly enhanced, and the partial discharge amount of the column switch is reduced.
Description
technical field [0001] The invention relates to a box body sealing structure and a sealing ring of a switch on a pole. Background technique [0002] The outlet bushing of the pole switch and the box body need to be sealed. The quality of the sealing performance here determines the gas concentration inside the pole switch. If the seal is not tight, the partial discharge of the switch will be affected. [0003] The Chinese patent application with the publication number CN107464723A and the publication date of 2017.12.12 discloses a pole-mounted SF6 composite switch. The load switch includes a shell, and the two sides of the shell are preset with round holes for installing the inlet and outlet bushings. , the rear panel of the housing is preset with a round hole for installing the internal components of the housing. The inlet and outlet sleeves are installed on the left and right sides of the housing. There is a shielding net in the bushing, which can reduce the partial discha...
