Background technology
Required according to standard GB/T 3906-2006,3.6kV-40.5kV switch cubicles must are fulfilled for type approval test requirement,
Wherein 1.1 times rated current temperature rise tests and internal fault test examine very harsh to switch cubicle.1.1 times of rated current temperature rises
The ventilation and heat ability of the main examination switch cubicle of test, 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 bear, it will the failure (such as short circuit extreme case) that generation can not be estimated；Send out
During raw internal fault, the splashing of particulate matter, also arc light and high-temperature gas can not be effectively prevented also can in pressure leak process
Cabinet is ejected in no direction, can affect maintainer's life security.How to be avoided that or limit both the above situation
Occur, greatly help will be brought to switch cubicle safe operation, while ensureing the personal safety of operating maintenance personnel.
The content of the invention
The technical problem to be solved, be just to provide one kind can meet switch cubicle temperature rise and internal fault pressure release will
The pressure relief device asked, effectively solving switch cubicle temperature rise is exceeded and internal fault, it is ensured that the normal operation of switch cubicle and maintainer
Personal safety.
Above-mentioned technical problem is solved, the technical solution used in the present invention is as follows：
A kind of pressure relief device for meeting switch cubicle temperature rise and internal fault pressure release requirement, 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 the mesh plate of multiple through holes, outer layer be provided with it is multiple
Laterally long lumbar hole, on two long flange fastening through hole is provided with, wherein the fastening through hole inner side of a long flange is provided with some lining up
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, described device is provided with the flange of long rectangular through-hole side and is directly bolted on the switch cubicle.
Further, the through hole of the mesh plate meets IP4X degree of protection requirements.
Further, the pressure relief device is coated with black paint, and the heat that absorption pressure release channel flows out is improved
Heat-sinking capability.
Preferably, the nylon bolt is M6 bolts.
Preferably, the mesh plate material is cold-rolled steel sheet.
Beneficial effect：
The present invention is a rectangle basin with the flanging being generally aligned in the same plane, and basin bottom is bilayer, and nexine is that mesh plate is uniform
There are multiple through holes, outer layer to be provided with multiple horizontal long lumbar holes, on two long flange fastening through hole is provided with, wherein the fastening of a long flange
With through hole inner side, some alinements are provided with and parallel to the long rectangular through-hole of long flange；The pressure relief device is connected with
In the outlet of the pressure relief channels of the switch cubicle StoreFront, wherein being provided with the fastening through hole adapted metal of long rectangular through-hole
The fastening through hole adapted nylon bolt of bolt, another long flange.The mesh plate is provided with and meets IP4X degree of protection requirements
Round tube hole.Pressure relief device spray black is painted, the heat that absorption pressure release channel flows out, and further improves heat-sinking capability.
During temperature rise test, the heat that Primary Conductor gives out is risen by pressure relief channels, and is filled by the pressure release
Put and timely and effectively shed heat toward outside switch cubicle, while the mesh plate can be intercepted outside the solid more than 1.0mm of outside
Thing is invaded in switch cubicle, affects equipment normal work.When inside is broken down, the false pressure of generation is logical along pressure release
Road pressure release, and pressure is applied on pressure relief device, now, nylon bolt is thrust under moment huge pressure, while square
Shape 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 final
Thus discharge, such pressure relief device is unlikely to be rushed winged, prevent its harm maintainer's personal safety.Therefore, the present invention can be full
Sufficient switch cubicle cooling and the requirement of failure pressure release, its simple structure is practical.
