Abstract
The utility model discloses a pressure release device of a high tension switch cabinet, comprising a pressure release plate arranged above a switch cabinet breaker room and above a bus-bar room. The pressure release device is characterized in that a flanging is arranged at left side of the pressure release plate, a hook is arranged at right side of the pressure release plate, and a row of rectangular holes are arranged near the flanging. By adopting the scheme, when an internal fault occurs in the switch cabinet, a cabinet door of the switch cabinet can not be opened because of increased internal pressure, thereby guaranteeing personal safety of an operator or a maintainer.
Description
Technical field
The utility model relates to a kind of electric device, refers to the pressure relief device of a kind of high-tension switch cabinet under the internal fault situation especially.
Background technology
High-tension switch cabinet be country the early 1990s by the product of switch cubicle manufacturer co-design strong in the organizing nation of high institute of west, because of this product has reliably " five is anti-" interlocking and good operating characteristics, present also have a very high occupancy volume on market.But this product is subjected to the limitation of mentality of designing at that time, under switch cubicle internal fault situation, when the increase of internal pressure, fail to design effective passage internal pressure released, because of this reason at home power supply department a lot of security incidents have appearred.
Summary of the invention
The pressure relief device that the purpose of this utility model is to provide a kind of high-tension switch cabinet at high-tension switch cabinet under the internal fault situation, the effective pressure relief device when the increase of internal pressure.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of pressure relief device of high-tension switch cabinet, include the pressure relief plate that is loaded on switch cubicle breaker chamber top and bus-bar room top, it is characterized in that: the left side of pressure relief plate is provided with flanging, the right is provided with hook, and the position of close flanging is provided with platoon leader's square hole.
Adopt such scheme, the position of close flanging is provided with platoon leader's square hole, artificially reduces armor plate strength, bending from here under the effect in internal pressure.In addition, adopt hook, catch on cabinet skeleton edge under the normal condition, guarantee the integrality of cabinet on the right of pressure relief plate, when switch cubicle under the internal fault situation, thereby effectively pressure release of deformation of hook when the increase of internal pressure.
The beneficial effects of the utility model are: when switch cubicle under the internal fault situation, can not wash door of switch cabinet open, thereby guarantee operation or maintainer's personal safety because of the increase of internal pressure.

Embodiment
With reference to accompanying drawing 1, the utility model comprises that pressure relief plate 1 is fixed on switch cubicle 3 breaker chambers 7 tops by 11 on M10 bolt 4 and the pressure relief plate A1; Pressure relief plate B2 is fixed on bus-bar room 6 tops of switch cubicle 3 by the hook 21 on bolt M10, bolt 5 and the pressure relief plate B2.
With reference to accompanying drawing 2, the left side of pressure relief plate is provided with flanging 12 (22), and the right is provided with hook 11 (12), and the position of close flanging is provided with platoon leader's square hole 23.
Break down in switch cubicle inside, the cabinet internal pressure rises, when internal pressure rise to overcome the resistance that pressure relief plate A1 and pressure relief plate B2 go up hook after, deformation of hook, pressure relief plate is from dashing the local bending that platoon leader's square hole is arranged, pressure is washed the pressure relief device pressure release open, thereby guarantees operation or maintainer's personal safety.
