Description
Technical field
The utility model relates to switch cubicle technical field, specifically a kind of explosion-proof back shroud of switch cubicle double door meeting switch cubicle back shroud requirement of explosion proof.
Background technology
High-tension switch cabinet, operationally for ensureing the safety of operator, requires that switch cubicle has enough explosion-proof capabilities when there is internal fault.In order to easy to maintenance, switch cubicle back shroud adopts the form of double door sometimes.The back shroud of this form, owing to cannot fix with switch cabinet two cover plate junctions, so intensity is poor, is the most weak link of back shroud explosion-proof capabilities.
Utility model content
The purpose of this utility model is to provide the explosion-proof back shroud of a kind of switch cubicle double door, fixing not firm to solve existing switch cubicle double door back shroud, the problem that explosion-proof capabilities is weak.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
The explosion-proof back shroud of a kind of switch cubicle double door, it is made up of symmetrical right cover plate, left cover, described right cover plate, left cover are arranged on cabinet with hinge respectively, the side that described right cover plate and described left cover connect extends left and is provided with U-type groove, several sleeve column is provided with in described U-type groove, the middle part of described sleeve column is provided with screwed hole, and described left cover is provided with the installing hole suitable with described screwed hole.
As further improvement of the utility model, the upper of described right cover plate, left cover is bolted on described cabinet below.
Further improve as of the present utility model, the quantity of described sleeve column is at least 3.
Right cover plate in the utility model is relative with left cover when closing, and inner surface and the described sleeve column of left cover fit, and both can be fixed together by fit on bolt in installing hole and screwed hole; The upper of right cover plate, left cover is bolted on cabinet below, and the surrounding of double door back shroud is all fixed on the cabinet of switch cubicle, effectively enhances the explosion-proof capabilities of back shroud.The utility model is easy to assembly, simple to operate, practical.
