Detailed description of the invention
Refer to Fig. 1, the present inventor is in order to carry out technical scheme of the present invention betterUnderstand, below by embodiment particularly, and be described in detail by reference to the accompanying drawings:
Refer to Fig. 1, the indoor reactor 1 that is provided with of a kind of underground substation of the present invention reactor, instituteThe inwall of stating reactor chamber, underground substation is provided with Smoke proofing and fire proofing shutter 2 and smoke-and fire-preventing valve 3,Smoke-and fire-preventing valve 3 is the exhaust blower 5 with this reactor chamber, underground substation aspect of living in by exhaust duct 4Be communicated with. Exhaust blower 5 is communicated with the exhaust air shaft of this underground substation.
In the time of the indoor middle breaking out of fire of this underground substation reactor, to this reactor chamber, underground substationSmoke proofing and fire proofing shutter 2 on Smoke Sensor make the Smoke proofing and fire proofing of this reactor chamber, underground substationShutter 2 and smoke-and fire-preventing valve 3 are closed, and exhaust blower 5 cuts out, to block the oxygen supply condition of fire,And stop the intensity of a fire to spread along exhaust duct 4. When confirming, after fire suppression, to open corresponding smoke-and fire-preventing valve3 and exhaust blower 5 carry out calamity rear venting.
On the outer wall of this reactor chamber, underground substation, be provided with exhaust smoke valve 6, smoke exhaust fan 8 and someExhaust opening 7, exhaust smoke valve 6 is positioned on the outer wall of this reactor chamber, underground substation, and smoke exhaust fan 8Connect, smoke exhaust fan 8 is connected with exhaust opening 7, and exhaust opening 8 leads to outside described transformer station. Exhaust opening8 adopt stainless (steel) wire air port. Exhaust smoke valve 6 is under normal circumstances in normally off, when environment temperature arrivesReach 280 DEG C of fuses on exhaust smoke valve 6 and automatically fuse, and link with smoke exhaust fan 8, control is openedSmoke exhaust fan 8.
After reactor chamber, described underground substation fire extinguishes, in 15S, automatically open its place aspectExhaust blower 5, its inner smoke-and fire-preventing valve 3 and Smoke proofing and fire proofing shutter 2, described in automatically closingThe fire resisting shutter of place, reactor chamber, underground substation aspect is closed described underground substation air-conditioning simultaneouslyMachine general supply. Opened smoke-discharging mouth 7, exhaust smoke valve 6, linkage is opened smoke exhaust fan 8 and is carried out machinery rowCigarette.
Burning has at the same time under combustible, oxidant and three primary conditions of ignition energy and could occur,In general, combustible and oxidant are ever-present, make them start to react to each other, and key existsIn enough ignition energies are provided. In addition, the oxidation reaction between combustible and oxidant is not directly to enterRow, but the intermediate material such as active group and atom that process generates in high temperature, by chain anti-Should carry out. If elimination activity group, chain reaction is interrupted, and continuous combustion process will stop.
Reactor indoor reactor in underground substation, under high temperature or arcing, can decomposite a large amount ofThe hydrocarbon of lightweight, such as the inflammable gas such as hydrogen, acetylene. These inflammable gases and air are mixedClose, while reaching finite concentration, form explosion gas, meet high temperature and will blast.
Reactor indoor fire in underground substation belongs to restricted clearance type fire, and Indoor Combustion existsTwo stages of Ventilation Control and fuel control. At the initial stage on fire, the size of scene of a fire size and restricted clearanceCompare very littlely, have enough oxygen supplies, Indoor Combustion situation by quantity of flammable substances and distribution situation certainlyFixed, along with fire continues development, flame range area increases, and the fuel gas that pyrolysis goes out is more and more, oxygenUnsaturated vapor is to maintain complete combustion of fuel, and burn rate turns by the air speed control in flowed into chamber,The Ventilation Control stage.
When reactor chamber, underground substation breaking out of fire, under fire control system effect, close air intakeShutter and air draft air-valve, door is all in normally off, and whole fire generating process will be rapidly from combustionMaterial is controlled stage conversion to the Ventilation Control stage, finally extinguishes fast because oxygen lacks.
Fire prevention for reactor chamber, underground substation also can adopt following measure:
Strengthen the quality of the indoor reactor of reactor, before installation, will carry out Insulation test, and carefully checkWhether all parts of reactor meets the demands, and after confirmation, could install;
Reactor on design of circuit system, should be considered various fire safety measures outside, as being equipped with fusingDevice or protective relaying device, catch fire in order to protection reactor unlikely circuit that causes when short circuit and the overload;Device housings is connected with grounded screen, reliable ground; Lead-in arranges arrester, prevents from being struck by lightning on fire etc.;
Ensure that reactor chamber ventilated is good, to ensure that environment temperature is lower than allowable temperature; The reactance of oil-containingDevice has draining collecting pit, in the time of fire, rapidly fuel oil is drained into safety zone; Water spray is setFire extinguishing system 9;
Backdraft phenomenon is an endemism in restricted clearance.
The existence of incendiary source is to cause a primary condition of strile-bacing. Generally can burning fume and the later stage enterThe burning mixture that generates of air doping do not reach ignition temperature, must be lighted by incendiary source. ?Underground substation reactor is indoor three class incendiary sources conventionally: the one, and naked light flame, the 2nd, temporary transient hiddenKindling material, the 3rd, spark.
Two necessary conditions of strile-bacing are: the change of leading burning and ventilation condition. At leading fireWhen calamity is not also extinguished completely, door or other ventilating openings are opened, and the cold air that is rich in oxygen can enter and be subject toLimit space, propagates in room with the form of gravity current, forms the change of ventilation condition, once depositAt incendiary source, the strile-back instantaneous formation of meeting, development, become typical retardance and strile-back.
For the generation that prevents from strile-bacing, the later stage of controlling fresh air flows into and has important function. IfNeed to open fire shutter 2 and smoke-and fire-preventing valve 3 in the situation that leading fire does not extinguish completely time,In along water spray fire extinguish system 9 to room, spray into water smoke, can effectively reduce the temperature of flue gas, thereby subtractLittle flue gas is lighted possibility, and this is also conducive to put out indoor naked light simultaneously.
When fire extinguishing, will reduce the indoor combustible concentration of underground substation reactor, burning is combustibleAnd the chemical reaction between oxide, lack wherein any all can cause fire extinguish. In reactionIn district, reduce with elimination combustible and can make system fire extinguishing. When the combustable gas concentration of reaction zone is reduced toCertain limit, combustion process just cannot maintain. By not combustion the combustible with firing separate can inDisconnected combustible is to the supply of combustion zone, i.e. isolation is put out a fire.
Reduce underground substation reactor indoor oxygen concentration, the supply of restriction oxygen is also the base of fire extinguishingThese means. After the oxygen concentration of reaction zone is lower than 15%, fire burning is just difficult to carry out, and suffocatesFire extinguishing.
From analyzing above, under worst operating mode, to reach rapid fire extinguishing, can consider to cut offOne of them of four key elements of burning or several. Such as using oil from reactor chamber, underground substation reactorTake out, rely on blocking-up combustible to block burning, but the most simple method is to control underground power transformationThe stand temperature of reactor chamber.
Reactor chamber, underground substation can adopt with the water spray fire extinguish system 9 of temperature sensor and fallLow temperature starts effect, and should act on after fire extinguishes always after 30s occurs fire,Until detecting the temperature of reactor chamber, described underground substation, temperature sensor drops to oil for reactorFlash-point safety just below. Should how long after extinguishing, fire act on as for water spray fire extinguish system 9,Suggestion should be possessed water spray fire extinguish system 9 after fire extinguishes Water-and mist-spraying effect in 30min.
Those of ordinary skill in the art will be appreciated that, above embodiment usesBright the present invention, and be not used as limitation of the invention, as long as in connotation scope of the present inventionIn, variation, modification to the above embodiment all will drop within the scope of claims of the present invention.
