Abstract
The utility model relates to an automatic recovery pressure release device disposed on a top of a centrally installed switchgear comprising a pressure release cover plate and a pressure release channel outlet. The pressure release cover plate is fixedly disposed on the pressure release channel outlet, and a front end of the pressure release cover plate is connected with a hinge, which can be used to reset the pressure release cover plate. By using the device provided in the utility model, when the release of the high pressure air flow occurs, the pressure release cover plate can be prevented from being deformed or damaged, and the safety accident caused by the shedding of the pressure release can be prevented. After the pressure is released, the pressure release cover plate can return to the original place instead of being replaced. Vent holes are additionally disposed in the periphery of the pressure release cover plate, the ventilation and the heat dissipation of the cabinet can be facilitated, therefore the service lifetime of the device can be prolonged, and the use safety of the device can be improved.
Description
Technical field
The utility model relates to the pressure relief device that a kind of middle-placed switch cabinet top can be recovered automatically, is mainly used in electric power complete set of equipments industry middle-placed switch cabinet top pressure relief device.
Background technology
Tradition middle-placed switch cabinet top breaker chamber, bus-bar room, top, cable vault pressure release cover plate, all be to adopt the cover plate form, the decompression cover prelaminar part divides the employing metal bolts to fix, the rear section adopts nylon bolt to fix, when breaking down in the cabinet or during accident, the high pressure draught that each functional unit produces will be by the pressure release of cabinet top pressure release cover plate, the rear section nylon bolt prior to cabinet before metal bolts come off, the pressure release cover plate is upwards raised by the high pressure draught active force, and release at high pressure draught top behind the cabinet.But pressure release when occuring in this scheme, pressure release cover plate meeting gross distortion or damage, and perhaps coming off flies out threatens life or device security, when restorer, need to again manufacture the pressure release cover plate and install.
The utility model content
Breaking down or during accidental depressurization for solving traditional pressure release cover plate, the danger that exists the pressure release cover plate to come off, the utility model provides a kind of middle-placed switch cabinet top can automatically recover pressure relief device, after high pressure draught releases, the pressure release cover plate can automatically restore to the service position, need not to change the pressure relief device of pressure release cover plate.
The technical solution adopted in the utility model: pressure relief device can be recovered automatically in a kind of middle-placed switch cabinet top, comprises pressure release cover plate, pressure release passage outlet; Described pressure release cover plate is fixed in the pressure release passage outlet; The decompression cover front edge of board connects the hinge that it is resetted.
Described pressure release cover plate rear end arranges the fixedly nylon bolt of pressure release cover plate.
Described decompression cover edges of boards are along being provided with ventilation hole.
Useful technique effect of the present utility model: when pressure release occurs, avoid pressure release cover plate meeting gross distortion or damage, the pressure release cover plate comes off and causes security incident, and pressure release cover plate self-return need not to change after the pressure release; The pressure release cover plate has been Duoed ventilation hole than traditional decompression cover panel area, more is conducive to ventilation and heat in the cabinet, improves service life of equipment and uses safety.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model uses the status architecture schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1 and Figure 2: pressure relief device can be recovered automatically in a kind of middle-placed switch cabinet top, comprises pressure release cover plate 1, pressure release passage outlet 5, and pressure release cover plate 1 is in pressure release passage outlet 5, and front end connects by hinge 3, and hinge 3 can make pressure release cover plate 1 reset; Described pressure release cover plate 1 rear end is fixing with nylon bolt 2.
When breaking down in the cabinet or during accident, the nylon bolt 2 of pressure release cover plate 1 rear end comes off, and upwards pushes up under the effect of high pressure draught, and pressure release cover plate 1 is upwards raised under the effect of hinge 3, after high pressure draught released, pressure release cover plate 1 automatically restored to the service position under Action of Gravity Field.
Described pressure release cover plate 1 edge is provided with ventilation hole 4, is beneficial to ventilation and heat in the cabinet, improves useful life and uses safety.
The utility model describes by accompanying drawing, in the situation that does not break away from the utility model scope, can also carry out various conversion and be equal to replacement the utility model patent, therefore, the utility model patent is not limited to disclosed specific implementation process, and should comprise the whole embodiments that fall in the utility model Patent right requirement scope.
