The ventilation and heat ability of the main examination switch cubicle of experiment, and require that switch board housing meets IP4X degree of protection；Internal fault is tried
Test the outer cover intensity and pressure relief channels pressure release promptness of main examination switch cubicle.Temperature rise is exceeded will to directly influence switch cubicle
Normally use, such as exceed the limit that switch cubicle can be born, it will occur the failure (such as short circuit extreme case) that can not be estimated；Hair
During raw internal fault, the splashing of particulate matter can not be effectively prevented in pressure leak process, also arc light and high-temperature gas also can
Cabinet is ejected in no direction, can influence maintainer's life security.How to be avoided that or limit both the above situation
Occur, very big help will be brought to switch cubicle safe operation, while ensureing the personal safety of operating maintenance personnel.
Utility model content
Technical problem to be solved in the utility model, is just to provide that one kind can meet switch cubicle temperature rise and internal fault is let out
The pressure relief device of pressure request, effectively solves that switch cubicle temperature rise is exceeded and internal fault, it is ensured that the normal operation and maintenance of switch cubicle
The personal safety of personnel.
Above-mentioned technical problem is solved, the technical solution adopted in the utility model is as follows：
A kind of pressure relief device for meeting switch cubicle temperature rise and internal fault pressure release requirement, it is characterized in that：There is position for one
In the rectangle basin of conplane flange, basin bottom is bilayer, nexine be evenly equipped with multiple through holes mesh plate, outer layer be provided with it is multiple
Fastening through hole is provided with horizontal long lumbar hole, two long flange, wherein being provided with some line up on the inside of the fastening through hole of a long flange
Straight line and parallel to the long rectangular through-hole of long flange；The pressure that the pressure relief device is bolted to above the switch cubicle is released
Put in the outlet of passage, wherein being provided with the fastening through hole adapted metal bolts of long rectangular through-hole, the fastening of another long flange is used
Through hole adapted nylon bolt.
Further, flange of the described device provided with long rectangular through-hole side is directly bolted on the switch cubicle.
Further, the through hole of the mesh plate meets IP4X degree of protection requirements.
Preferably, the nylon bolt is M6 bolts.
Beneficial effect：
The utility model is a rectangle basin with the flanging being generally aligned in the same plane, and basin bottom is bilayer, and nexine is mesh plate
It is evenly equipped with multiple through holes, outer layer and is provided with multiple horizontal long lumbar holes, two long flange and is provided with fastening through hole, wherein a long flange
On the inside of fastening through hole, some alinements are provided with and parallel to the long rectangular through-hole of long flange；The pressure relief device bolt
In the outlet for being connected to the pressure relief channels of the switch cubicle StoreFront, wherein the fastening for being provided with long rectangular through-hole through hole adapted
The fastening through hole adapted nylon bolt of metal bolts, another long flange.The mesh plate is wanted provided with IP4X degree of protection is met
The round tube hole asked.During temperature rise test, the heat that Primary Conductor gives out is risen by pressure relief channels, and passes through the pressure release
Device is toward the heat that timely and effectively sheds outside switch cubicle, while the mesh plate can obstruct the solid more than 1.0mm of outside
In foreign object intrusion switch cubicle, equipment normal work is influenceed.When inside is broken down, the false pressure of generation discharges along pressure
Passage pressure release, and pressure is applied on pressure relief device, now, nylon bolt are thrust under moment huge pressure, simultaneously
Rectangle long through-hole position will be by impact bending, and pressure relief device is raised to metal bolts side is connected with, and false pressure is most
Thus discharge eventually, such pressure relief device is unlikely to be rushed winged, prevent it and endanger maintainer's personal safety.Therefore, this practicality is new
Type can meet the requirement of switch cubicle cooling and failure pressure release, and its is simple in construction, practical.

Embodiment
The utility model is further described with reference to embodiment.
Specific embodiment：As shown in Figure 1 to Figure 3, the present embodiment is a rectangle basin with the flange being generally aligned in the same plane,
Basin bottom is bilayer, and nexine is that mesh plate 1, the outer layer for being evenly equipped with multiple through holes 11 are provided with multiple horizontal long lumbar holes 21, and two length turn over 3 sides
On be provided with fastening through hole 21, wherein the inner side of fastening through hole 2121 of a long flange 2 be provided with some alinements and parallel to
The long rectangular through-hole 22 of long flange；The pressure relief device is bolted to the pressure relief channels 7 above the switch cubicle 6
In outlet, wherein being provided with the fastening of long rectangular through-hole 22 with the adapted metal bolts 8 of through hole 21, the fastening through hole of another long flange
21 adapted nylon bolts 9.Device is cold-rolled steel sheet and is coated with black paint, absorbs heat during 6 temperature rise of switch cubicle, improves and dissipates
