Abstract
The invention discloses a kind of switch cubicle being provided with pressure relief device, include gas tank, cable vault and pressure releasing chamber, on the left plate that described gas tank is contained in described cabinet and right plate, described cable vault is surrounded by cabinet left plate, right plate, front lower door-plate, median septum, and described pressure releasing chamber is surrounded by cabinet left plate, right plate, median septum, rear shrouding.The base plate of described pressure releasing chamber has relief hole, and the bottom of the median septum between described cable vault and described pressure releasing chamber has the unidirectional relief hole can only opened to described pressure releasing chamber.Have the relief hole be connected with other switch group cabinet in the bottom of the right plate of described pressure releasing chamber, as this cabinet is used alone, have one block of shrouding to be shut by this relief hole.Compared with prior art, the invention solves because the gas tank gases at high pressure that produce after blast or the blast of cable catastrophic failure that meet accident can not discharge security hidden trouble outside cabinet in time.
Description
Technical field
The present invention relates to the safety relief mode technical field of switch cubicle, particularly a kind of switch cubicle being provided with pressure relief device.
Technical background
Current, in the sulfur hexafluoride gas-insulating ring main unit in 12kV/24kV distribution system, when the explosion time that breaks down, as blast the gases at high pressure that produce can not get dredging timely, all accumulate in cabinet inside, likely product is all damaged, lead to larger security incident.And existing air-box type ring main unit is due to Design and manufacture defect, do not have special pressure relief device, the gases at high pressure produced that fault can not be exploded are discharged outside cabinet timely, there are major safety risks.
Summary of the invention
Problem to be solved by this invention is to provide a kind of switch cubicle being provided with pressure relief device outside the discharge cabinet of the gases at high pressure produced that can explode in time, rapidly by fault.
To achieve these goals, technical scheme of the present invention is: this switch cubicle being provided with pressure relief device includes the cable vault be connected under gas tank, side, cable vault under described gas tank is provided with the pressure releasing chamber be connected on outside described gas tank pressure relief opening, the base plate of described pressure releasing chamber has base plate relief hole; Median septum between described cable vault and described pressure releasing chamber is provided with and has dividing plate relief hole, and this dividing plate relief hole is equipped with air-flow flows to described pressure releasing chamber check valve sheet from described cable vault.
Above-mentioned is provided with in the technical scheme of the switch cubicle of pressure relief device, can also be more specifically: be provided with the side relief hole for being communicated with other switch group cabinet at the side plate of described pressure releasing chamber.
Owing to have employed such scheme, the present invention compared with prior art has following beneficial effect:
1, the pressure release passage of pressure releasing chamber is all be sealed in an independent interval by aluminizing zinc metallic plate, meanwhile, is cable trough immediately below its pressure relief opening, and gas tank pressure release can directly be walked toward cable trough direction, and structure is simple, easy to make;
2, the pressure release passage of cable vault is also be sealed in a three side sealing by aluminizing zinc metallic plate to close in interval, the relief hole being provided with one-way conduction only on the median septum leading to rear portion pressure releasing chamber, the gas produced during fault can not toward front end punching press, cable trough can only be arrived through rear portion pressure releasing chamber, outside discharge cabinet, very safe and reliable.
Two kinds of above passages are separate, can complement each other again, further increase security reliability when breaking down.
Accompanying drawing explanation
Fig. 1 is the front view that the embodiment of the present invention is provided with the switch cubicle of pressure relief device.
Fig. 2 is the vertical view cutaway drawing that the embodiment of the present invention is provided with the switch cubicle of pressure relief device.
Fig. 3 is the rear cross sectional view that the embodiment of the present invention is provided with the switch cubicle of pressure relief device.
Embodiment
Below in conjunction with the present invention's concrete accompanying drawing embodiment, the present invention is described in further detail.
The switch cubicle being provided with pressure relief device shown in Fig. 1, Fig. 2 and Fig. 3 has a gas tank 2, a cable vault 1 and a pressure releasing chamber 14 is connected in the below of gas tank 2, pressure releasing chamber 14 terminates on described gas tank 2 pressure relief opening 3, the base plate of pressure releasing chamber 14 has base plate relief hole 15; Isolated by median septum 4 between cable vault 1 and pressure releasing chamber 14, median septum 4 is provided with dividing plate relief hole, check valve sheet 6 is connected with by hinge 5 in pressure releasing chamber 14 side of median septum 4, check valve sheet 6 is greater than dividing plate relief hole, make the explosion air-flow of cable vault 1 can enter pressure releasing chamber 14 from cable vault 1 by dividing plate relief hole, and the explosion air-flow of pressure releasing chamber 14 can not be allowed to enter cable vault 1 by dividing plate relief hole.The side plate 12 of pressure releasing chamber 14 being also provided with the side relief hole 8 for being communicated with other switch cubicle, other switch cubicle blasting fume can be allowed to discharge from the pressure releasing chamber 14 of this cabinet.If when this cabinet does not need with his group cabinet, side relief hole 8 can be closed with shrouding 7.
