Abstract

The invention discloses a voltage release device of an electrical switch cabinet. The voltage release device is characterized by comprising a voltage release hood arranged at the top of the switch cabinet, wherein four corners of the voltage release hood are connected with the edge of the top of the switch cabinet through bolts; a compression spring sleeves the lower end of each bolt, and is finally fixed by nuts, so that a certain distance is retained between the nuts and the top of the switch cabinet; voltage release holes are also formed in the periphery of the voltage release hood; rotating strips are further arranged at the lower parts of the bolts; and rotating grooves matched with the rotating strips are formed in through holes where the bolts at the edge of the top of the switch cabinet pass. The voltage release device is simple in structure and convenient to use; when equipment works normally, the voltage release holes in the periphery of the voltage release hood can help the interior of the switch cabinet to be ventilated and dissipated, so that the probability of internal fault occurring is reduced.

Description

technical field [0001] The invention relates to a pressure relief device for an electric switch cabinet. Background technique [0002] The switchgear is a large electrical equipment with a large number of electronic components inside, which will generate a lot of heat during operation; during normal operation, the heat will be dissipated through the cooling holes on the switchgear body. However, once the internal components of the switchgear fail, a large amount of heat and pressure will be generated, and the heat dissipation holes on the switchgear body cannot quickly release the energy inside the switchgear body, which may cause the danger of the switchgear explosion, bringing Huge security risks and economic losses. Contents of the invention [0003] The object of the present invention is to provide a pressure relief device for an electrical switchgear. [0004] In order to achieve the above object, the following technical solution is adopted, an electrical switch c...
