Abstract
The invention discloses a kind of self-extinguishing switch cubicle, including casing, extinguishing agent storage room, extinguishing chemical, extinguishing agent storage is in extinguishing agent storage room, wherein rupture disk is on internal face, there is line of weakness on the substrate of rupture disk, cover plate covers in the space in the region that line of weakness is surrounded, cover plate and substrate and fills blasting agent.When the equipment in switch cubicle is caught fire, the blasting agent in switch cubicle in moment generation high temperature, rupture disk is by thermal explosion, and the active force that blast is produced tears rupture disk, and extinguishing chemical is ejected into switch cubicle extinguishes the blaze in time.
Description
Technical field
The present invention relates to electrical equipment, more particularly to a kind of self-extinguishing switch cubicle.
Background technology
Switch cubicle is widely used in electric power association area, prevents that inside switch cabinet generation fire is particularly significant, at present very
Many switch cubicles all carry automatic fire-extinguishing function, and automatic fire-extinguishing function needs electric energy mostly, and power supply of the electric energy in switch cubicle is supplied
Electricity, but automatic fire extinguishing system directly may be placed in paralysis shape when inside switch cabinet transcient short circuit time is on fire or releases high voltage
State, automatic fire extinguishing system may not have any effect, and perform practically no function.
The content of the invention
The present invention provides a kind of self-extinguishing switch cubicle, to solve switch cubicle extinguishing device because power-fail can not be automatic
The problem of startup.
To achieve the above object, the present invention provides a kind of self-extinguishing switch cubicle, including：Casing, extinguishing agent storage room, go out
Fiery agent, extinguishing agent storage is in extinguishing agent storage room, and wherein rupture disk has indentation on internal face on the substrate of rupture disk
Line, cover plate covers in the space in the region that line of weakness is surrounded, cover plate and substrate and fills blasting agent.
Preferably, the blasting agent in rupture disk selects ammonium nitrate.
Preferably, the line of weakness closure.
Preferably, line of weakness is carved into the depth difference of substrate.
Preferably, the extinguishing chemical selects powder extinguishing agent.
Preferably, the gas of compression extinguishing chemical selects nitrogen.
Preferably, side pipe is installed, side pipe is connected with nitrogen supply (NS) device on the wall of casing.
From the above description it can be seen that the force of explosion that the blasting agent in rupture disk is produced when a fire can be by rupture disk
Tear, extinguishing chemical can timely be sprayed onto in switch cubicle and extinguish the blaze.
Brief description of the drawings
Fig. 1 is the sectional view of self-extinguishing switch cubicle；
Fig. 2 is the sectional view of rupture disk；
Fig. 3 is the front view of rupture disk.
In figure：1- casings, 2- extinguishing agent storages room, 3- rupture disks, 4- blasting agents, 5- extinguishing chemicals, 6- side pipes, 7- inwalls
Face, 8- substrates, 9- line of weakness, 10- cover plates.
Specific embodiment
To make those skilled in the art be better understood from technical scheme, specific embodiment is given below
The present invention is made further instructions.
Fig. 1 to Fig. 3 shows the concrete structure of the present invention.The self-extinguishing switch cubicle of the present invention, including：Casing 1, fire extinguishing
Agent storage room 2, extinguishing chemical 5, extinguishing chemical 5 are stored in extinguishing agent storage room 2, wherein, rupture disk 3 is on internal face 7, explosion
There is line of weakness 9 on the substrate of piece 3, cover plate 10 is covered to be filled in the space in the region that line of weakness 9 is surrounded, cover plate 10 and substrate 8
Fill out blasting agent 4.When fire occurs in switch cubicle, moment produces high temperature in case.Blasting agent 4 in rupture disk 3 is made by high temperature
With that can produce blast, now rupture disk is due to the meeting decomposition by power, and the extinguishing chemical 5 in extinguishing agent storage room 2 is stored up by extinguishing chemical
Deposit the effect of compressed gas in room 2 and can be ejected into switch cubicle and put out fire in time.
It is preferred that, the blasting agent 4 in rupture disk 3 selects ammonium nitrate.Ammonium nitrate is stable in room temperature, can occur when heated quick-fried
Fried property is decomposed, and can guarantee that extinguishing device starts within the most short time using ammonium nitrate in rupture disk 3, it is to avoid the intensity of a fire, which expands, to be produced
Secondary disaster.
It is preferred that, the line of weakness 9 is closed.Further preferably, line of weakness 9 is carved into the depth difference of substrate 8.Line of weakness 9 is adopted
It can guarantee that on substrate there are multiple weak load-bearing points with the design of closed type.Line of weakness 9 is carved into the different design of depth of substrate 8
Some points on substrate 8 can be made to be torn easily when being impacted.As the closure of line of weakness 9 refers to the first place of line of weakness 9 in Fig. 3
It is connected and surrounds the annular of a closing.
It is preferred that, extinguishing chemical 5 selects powder extinguishing agent.Further preferably, the gas of compression extinguishing chemical 5 selects nitrogen.
Further preferably, side pipe 6 is installed, side pipe 6 is connected with nitrogen supply (NS) device on the wall of casing.Nitrogen supply (NS) is filled
Put can guarantee that fire extinguishing storage room 2 in maintain appropriate pressure, it is to avoid cause because of the slow gas leakage in extinguishing agent storage room 2 fire extinguishing imitate
Fruit weakens.Nitrogen is also inert gas simultaneously, and nitrogen can be full of switch cubicle for a long time after rupture disk 3 is torn, it is to avoid because
Temperature in cabinet is too high to cause equipment in cabinet to be burnt again.
Embodiments of the present invention are explained in detail above in conjunction with accompanying drawing, but the present invention is not limited to above-mentioned implementation
Mode, in the knowledge that those skilled in the art possess, can also make on the premise of present inventive concept is not departed from
Various change.
