Due to their unique advantages, dry-type transformers are widely used in various occasions, such as power transmission and transformation systems in factory workshops, high-rise buildings, commercial centers, airports, docks, subways, oil platforms, etc. Dry-type transformers can be combined with switchgear to form a compact complete substation, which is particularly suitable for places with high fire and explosion protection requirements. In addition, dry-type transformers can also be used in important places such as local lighting, high-rise buildings, airports, as well as places with harsh environments such as subways, smelting power plants, ships, and offshore drilling platforms.

[0037] By setting a hand wheel 213, the worm 206 can be driven to rotate by the hand wheel 213, which plays a transmission role. By setting a through hole 12, it is convenient for the plug rod 212 to be inserted into the plug hole 203. By setting a slider 10 and a slide groove 11, the slider 10 can be driven to slide in the inner cavity of the slide groove 11 when the threaded sleeve 209 moves, thereby improving the stability of the threaded sleeve 209 during movement. By setting a guide groove 13 and a guide block 14, the guide block 14 can be driven to slide in the inner cavity of the guide groove 13 when the L-shaped rod 211 moves, thereby improving the stability of the L-shaped rod 211 during movement.

Since the fan 8 is installed inside the bellows 7, when it is necessary to maintain and repair the fan 8, the worm 206 is driven to rotate by the hand wheel 213, and the worm 206 drives the worm gear 207 to rotate through the action of the teeth meshing, and the worm gear 207 drives the bidirectional threaded rod 208 to rotate, and the bidirectional threaded rod 208 drives the threaded sleeve 209 to move outward through the action of the threaded connection, and the threaded sleeve 209 drives the welding rod 210, the L-shaped rod 211 and the insertion rod 212 to move outward, so that the insertion rod 212 is separated from the inner cavity of the insertion hole 203, and the bellows 7 is pulled outward, so that the bellows 7 drives the clamping block 201 to separate from the inner cavity of the clamping slot 202, so as to facilitate the maintenance or repair of the fan 8 inside the bellows 7;

[0039] When the bellows 7 needs to be installed, the fan 8 is first connected to the inner cavity of the slot 202 through the clamping block 201, and the worm 206 is driven to rotate in the opposite direction by the hand wheel 213. The worm 206 drives the worm wheel 207 to rotate through the action of the teeth meshing, and the worm wheel 207 drives the bidirectional threaded rod 208 to rotate.
