Description
Technical field
The utility model relates to a kind of pressure relief device, particularly relates to a kind of overhead type high-voltage board pressure relief device.
Background technology
The problem of high-temperature gas earth pressure release when overhead type high-tension switch cabinet mostly structurally all considers fault.The top of the handcart room in traditional high-tension switch cabinet, bus-bar room and cable vault is equipped with pressure relief device, this pressure relief device is generally connected with the gases at high pressure release channel in cabinet, its structure adopts L-type pressure release cover plate, side metallic screw and nylon screw or hinges fixing fix on top cover, and opposite side nylon screw is fixed.When breaking down in cabinet, HTHP thrusts nylon screw, and the distortion of pressure release cover plate is opened, release pressure and vented gasses.This scheme following points defect: with the passing of time agingly stressedly cannot confirming of nylon screw, the nylon screw head ruptured during pressure release can be released; Screw connecting mode is when pressure release, and L-type pressure release cover plate, without obvious weak spot, causes pressure release not smooth; Chain connection mode is when pressure release, and decompression cover plate hight speed is upspring, and prolongs hinge axis and overturns before cabinet, forces front pressure release passage high temperature gas flow to be discharged by high-voltage board front, causes the serious accident of operating personnel's serious burn.
Utility model content
The utility model is applied in high-voltage board pressure release scheme, adopts pressure release cover plate and the combination of fluting socket cap axial screw, cancels the application of nylon screw, solves the nylon screw that traditional scheme ruptures when pressure release and flies out; Cancel hinge links pressure release cover plate simultaneously, solve fast the upspringing of decompression cover plate hight and accidentally injure the phenomenon of people, improve the security performance of mechanism.
For achieving the above object, the technical solution of the utility model is: a kind of overhead type high-voltage board pressure relief device, it is characterized in that, comprise high-voltage board cabinet, high-voltage board top cover and pressure release cover plate, the side of pressure release cover plate is fixed on high-voltage board top cover by the first securing member, the opposite side of pressure release cover plate is provided with several grooves, second securing member is fixed on high-voltage board top cover through groove, pressure release cover plate is provided with several through holes by the side that the first securing member is fixing, handcart room is provided with in described high-voltage board cabinet, bus-bar room and cable vault, described handcart room, bus-bar room and cable vault are all arranged at below pressure release cover plate.
Preferably, described through hole is long lumbar hole, and described groove is arc groove.
Preferably, described pressure release cover plate is L-type, and described L-type comprises flange side and horizontal side, and described decompression cover sheet material matter is aluminum-zinc alloy sheet material.
Preferably, described first securing member comprises screw hole and Self-locking screw, and described first securing member is arranged between the long lumbar hole of pressure release cover plate and flange side.
Preferably, described second securing member is fluting socket cap axial screw.
Preferably, fluting socket cap axial screw axle center is no more than 6mm to decompression cover panel edges length.
The beneficial effect that the utility model reaches: a kind of overhead type high-voltage board pressure relief device described in the utility model is fixedly connected with by flexible connection by pressure release cover plate instead, namely the effect closing high-voltage board cabinet is at ordinary times reached, play dust-proof effect, can reach again when breaking down in high-voltage board, prevent the object that pressure release cover plate is upspring fast around hinge axis, pressure release passage is large, safe and effective; Described a kind of overhead type high-voltage board pressure relief device by the setting of fluting socket cap axial screw, compared with conventional nylon screw, can not be aging when variation of ambient temperature, and do not have when pressure release and fly to rush down thing, improve the reliability of device; Described a kind of overhead type high-voltage board pressure relief device is by the setting of long lumbar hole, and pressure release cover plate, from long lumbar hole flanging, opens pressure release passage, and release high temperature and high pressure gas, guarantees that pressure release cover plate is connected with high-voltage board cabinet simultaneously; Described a kind of overhead type high-voltage board pressure relief device is no more than the setting of 6mm to decompression cover panel edges length by fluting socket cap axial screw axle center, pressure release cover plate side can be made to extract out fast from fluting socket cap axial screw, and pressure release speed is fast.
