Abstract
The utility model discloses a pressure release apparatus for an indoor switch cabinet, comprising a lower top cover (1) and a pressure release cover (2), wherein three sides of the pressure release cover (2) are bended, one side of the pressure release cover is provided with a long circular hole (10), both sides of the long circular hole (10) are not bended, and the long circular hole (10) is fixed on the lower top cover (1) through a riveting nut (3), a flat gasket, a spring gasket (5) and a bolt (6), the other side of the pressure release cover (2) is provided with a semicircular hole (11), and the semi-circular hole (11) is fixed on the lower top cover (1) through a riveting nut (8), a flat gasket (9) and a nylon bolt (7), and the flat gasket (9) presses a position for 2 mm of the semi-circular hole (11). In accidents, the pressure release side deforms under an external force and extends out of the flat gasket (9), the long circular hole (10) on the pressure release cover (2) is used for edge folding, a pressure release channel is completely opened, thereby playing an effect of pressure release.
Description
Technical field
The utility model relates to the pressure relief device of the indoor switch cabinet in a kind of electrical power distribution system.
Background technology
In electrical power distribution system, there is a kind of hidden danger in switch cubicle always, namely be short-circuited or other accident when causing power distribution cabinet to blast accident when switch cubicle, pressure release passage can not play the pressure release effect well, have even distribution cabinet door all is out of shape and pressure release passage still can not be opened, even opening of having neither preferentially be opened, this will can cause certain injury to personnel inevitably.
The utility model content
The purpose of this utility model is to provide a kind of pressure relief device of indoor switch cabinet.
The technical solution adopted in the utility model is: a kind of pressure relief device of indoor switch cabinet, formed by lower top cover and decompression cover, three bendings of decompression cover, one side is equipped with slotted hole, and the slotted hole both sides do not have bending, and by staking nut, plain washer, spring washer be bolted on the lower top cover, the decompression cover opposite side is that the pressure release side has semicircle orifice, be fixed on the lower top cover by staking nut, plain washer and nylon bolt, plain washer is pushed down the approximately position of 2mm of semicircle orifice.
The indoor switch cabinet pressure relief device that the utility model provides is installed in top, cabinet top, when being subject to power, the pressure release side can be out of shape and be broken away from plain washer pressure release passage is opened fully the very first time, carries out flanging by the slotted hole on the decompression cover, pressure release passage is opened fully, plays the effect of pressure release.
Through verification experimental verification, the pressure relief device of the utility model indoor switch cabinet can make pressure release passage open passage in the moment that has an accident air pressure to be discharged, considerably beyond people's safe distance, accomplish the personnel's that guarantee safety.
