Waterproof and ash-blocking structure of transformer case

Abstract

The invention discloses a waterproof and ash-blocking structure of a transformer case. The structure comprises a case body, a block cover, two partition plates and a guide plate, multiple first vent holes, a drainage groove and a mounting groove are formed in the side wall of the case body, the multiple first vent holes are formed in a layered mode, the drainage groove is formed below the first vent holes, the mounting groove is formed in the inner side of the case body, and the mounting groove is communicated with the first vent holes and the drainage groove; the block cover is fixed to the inner wall of the case body and closes the mounting groove, the two partition plates are arranged in the block cover at a certain interval, the two partition plates are arranged in a parallel and staggered mode, the guide plate is arranged in the block cover in an inclined mode, one end of the guide plate is fixedly connected with the partition plate on the inner side, and the other end of the guide plate is fixedly connected with the inner wall of the block cover. Accordingly, heat in the case body can be given out conveniently, in rainy season, rainwater cannot enter the case body, and the blocked rainwater is drained into a cone-shaped groove through the guide plate and drained out of the case body through the drainage groove.

Description

Technical field: [0001] The invention relates to a waterproof and dust-retaining structure for a transformer casing. Background technique: [0002] When the existing transformer housing is in use, in order to dissipate the heat of the transformer, shutters are often arranged on the housing. When the shutters are in use, they cannot effectively prevent the entry of dust and rainwater, and the use effect is not good. Invention content: [0003] The present invention provides a waterproof and dust-retaining structure for a transformer shell in order to solve the above-mentioned problems in the prior art. [0004] The technical solutions adopted in the present invention include: a waterproof and dust-retaining structure for a transformer shell, including a shell, a shield, a partition and a guide plate, and a first ventilation hole, a drainage groove and an installation groove are arranged on the side wall of the shell , several first ventilation holes are arranged in layers,...
