Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer technology, specifically to an explosion-proof dry-type transformer that is easy to replace. Background Technology

[0002] Chinese Patent Publication No. (CN221239474U) discloses an explosion-proof dry-type transformer, including a first base, an explosion-proof dry-type transformer body mounted on top of the first base, a second base mounted on top of the explosion-proof dry-type transformer body, a protective mechanism on the outer wall of the first base, and a movable mechanism at the bottom of the first base. This explosion-proof dry-type transformer, by incorporating a protective mechanism and a protective net, effectively protects the transformer body from impacts by flying sand and rocks in the mine, reducing damage to the transformer body shell and its internal core, thereby extending the overall service life of the transformer body. It also does not affect the heat dissipation effect of the transformer body. The inclusion of a first connecting plate, a second connecting plate, and a tie rod facilitates the fixing of the protective net by workers.

[0003] The drawback of the aforementioned selected technology is that the protective net is installed on the first column by hinge rotation. However, when the protective net is severely deformed by the impact of gravel, the staff cannot disassemble and replace the protective net, which affects the subsequent protection effect of the transformer.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 5 This utility model provides a technical solution: an explosion-proof dry-type transformer that is easy to replace, including a base plate 1 and a dry-type transformer body 2 set on the base plate 1. First explosion-proof mesh plates 3 are symmetrically fixedly connected to the top two sides of the base plate 1. The corners of the two first explosion-proof mesh plates 3 are set with an L-shaped structure. A second explosion-proof mesh plate 4 is detachably set between the two first explosion-proof mesh plates 3. The second explosion-proof mesh plate 4 fits the inner wall of the two L-shaped first explosion-proof mesh plates 3. A third explosion-proof mesh plate 5 is detachably set on the second explosion-proof mesh plate 4 and the first explosion-proof mesh plate 3. A fixing bolt 11 is set on the second explosion-proof mesh plate 4. The fixing bolt 11 can realize the fixation between the second explosion-proof mesh plate 4, the first explosion-proof mesh plate 3 and the third explosion-proof mesh plate 5. The installation sequence can be to first insert the second explosion-proof mesh plate 4 between the two first explosion-proof mesh plates 3, then fasten the third explosion-proof mesh plate 5, and finally tighten the fixing bolt 11 to achieve uniform fixation.

[0019] The base plate 1 has a slot 13, and the second explosion-proof mesh plate 4 can be inserted into the base plate 1 through the slot 13. The first explosion-proof mesh plate 3 has a fixing groove 9, and the third explosion-proof mesh plate 5 has a fixing protrusion 7 that cooperates with the fixing groove 9. The third explosion-proof mesh plate 5 and the first explosion-proof mesh plate 3 can be connected by the insertion of the fixing protrusion 7 and the fixing groove 9.

[0020] The first explosion-proof mesh plate 3 has a second fixing hole 12, and the third explosion-proof mesh plate 5 has a first fixing hole 8. The fixing bolt 11 can pass through the second fixing hole 12 and the first fixing hole 8 in sequence to lock and fix the second explosion-proof mesh plate 4, the first explosion-proof mesh plate 3, and the third explosion-proof mesh plate 5.

[0021] The third explosion-proof mesh plate 5 is fixedly connected to both sides with handles 6. When the first explosion-proof mesh plate 3, the second explosion-proof mesh plate 4, and the third explosion-proof mesh plate 5 need to be disassembled and replaced, the third explosion-proof mesh plate 5 can be easily removed by holding the handles 6.

[0022] Among them, casters 10 are fixedly installed at the four corners of the top of the base plate 1, which can facilitate the movement of the dry-type transformer body 2.

[0023] Specifically, when it is necessary to disassemble and replace the first explosion-proof mesh plate 3, the second explosion-proof mesh plate 4, and the third explosion-proof mesh plate 5, the fixing bolt 11 can be unscrewed to disengage it from the second fixing hole 12 and the first fixing hole 8. Then, the third explosion-proof mesh plate 5 can be removed by holding the handle 6 upwards. Then, the second explosion-proof mesh plate 4 can be pulled out to disengage it from the slot 13, which facilitates the maintenance of the dry-type transformer body 2 by the staff.
