Description
Technical field
The utility model relates to a kind of automatic fire extinguishers of power transformer.
Background technique
Power transformer plays the function of " heart " in the power system, is the indispensable important portion of electric system
Part will lead to the power network paralysis in whole region once breaking down；Especially filled with dozens or even hundreds of ton in its body
Insulating oil (as insulation, coolant and heat-insulated use), power transformer run when working oil temperature generally at 50 DEG C~70 DEG C
Left and right, highest oil meter face temperature do not exceed 95 DEG C, therefore, especially just open when temperature reaches 400 DEG C in fault time
Begin to generate slight decomposition, if keeping this temperature-resistant for a long time, will decomposite methane, ethane and propane etc. be full of it is hydrocarbon
Compound；If overtemperature is greater than 400 DEG C, the decomposition rate of transformer oil aggravates, and mainly generates ethylene, propylene etc. no at this time
Saturated hydrocarbon；When temperature increases even up to 800 DEG C again, the capacity of decomposition of transformer oil is most strong；Work as overtemperature
When more than 800 DEG C, transformer oil almost all is decomposed into hydrogen, methane and acetylene.Electric power transformer insulated oil is at high operating temperatures
After gasifying, have all burning conditions of comburant: the various fuel gas generated after combustible-insulation oil gasification；It is high
In the temperature-iron core persistent fever or high-energy discharge of burning point；Air around combustion-supporting material-transformer.
In the equipment of electric system, route or power transformer interior fault, if relay protection (all kinds of protections of transformer
It is aftermentioned) miss operation or movement not in time, the temperature for making transformer oil is risen at a terrific speed in a very short period of time, produce
Raw excessive fuel gas has had little time to be dissolved by transformer oil, and the vaporized transformer oil volume to increase sharply is anxious
Play expansion, once the body of transformer has weak part (such as transformer porcelain sleeve, body weld seam, venting etc.) that will be broken into and split
Mouthful, spray transformer oil and the fuel gas of generation from breach together, the transformer oil of ejection and the temperature of fuel gas are closed
Object just generates flame or explosion after contacting with windage.
Existing fire extinguisher for transformer has: water spray fire extinguishing system, oil-drainage nitrogen-filling fire-extinguishing, gas self-extinguishing system
Deng.But existing transformer many places exist in outdoor outdoor pattern, surrounding is in spacious environment.Existing fire extinguishing system is deposited
:
1, it can be sprayed onto spacious space after extinguishing chemical sprinkling, effective fire extinguishing and fire prevention can not be formed for transformer,
The spot fire of fire behavior re-ignition is not can effectively prevent.
2, fire is generated in spacious space, transformer periphery fire behavior is be easy to cause to extend, the extinguishing chemical short time is by transformation
The fire suppression of device, but the presence of the fire behavior on periphery can cause secondary re-ignition and fire.
3, extinguishing chemical loss is big, and especially in the case where there is wind, extinguishing chemical floats in the air with the wind, can not go out at the first time
Fire.And then it can not effectively put out a fire.
4, any fire extinguishing system, fire-fighting dose is all to limit, can not be to spacious environment under a certain amount of extinguishing chemical
Comprehensively put out a fire and prevented the secondary re-ignition of fire.

Detailed description of the invention
Fig. 1 is the structure chart of the preferred embodiment in the utility model.
Specific embodiment
In order to which the technical solution of further explanation the utility model patent carries out detailed followed by specific example
Thin elaboration.
With reference to Fig. 1, a kind of automatic fire extinguisher of power transformer, comprising: interrupter 1, fire suppression mechanism 2, fire are visited
Survey device and control mechanism；
The interrupter 1 is located at outside power transformer 4, and by control mechanism controls in opening state and closed state
Between switch；When interrupter 1 is in an open state, the space between interrupter 1 and power transformer 4 is open space；
When the interrupter 1 is closed state, the space between interrupter 1 and power transformer 4 is hemi-closure space；
The ontology 21 of the fire suppression mechanism 2 is arranged outside interrupter 1, sky of the nozzle 22 towards the hemi-closure space
Between；
When the fire detector detects the generation fire of power transformer 4, control mechanism control interrupter 1 is switched to
After closed state, the fire suppression mechanism 2 passes through nozzle 22 to hemi-closure space spraying fire-extinguishing agent.In the present embodiment, the fire
Detector is perhaps detected transformer oil, the fuel gas that transformer generates or is known using fire behavior pattern by detection temperature
Not, infrared thermal imaging identification technology achievees the purpose that fire detection.
Therefore, when fire occurs, start fire-proof plate or fire screen and power transformer 4 and surrounding enviroment isolation get up,
Power transformer 4 is set to be in relative closure or semi-enclosed environment.It prevents combustible from leaking, completely cuts off the combustible and oxygen on periphery
Gas.To which fire behavior control in a smaller range, be helped to concentrate quick extinguishing.After extinguishing chemical sprinkling, opposite
In the environment of closing, can effectively it shield for a long time to power transformer 4.So that the device play fire prevention,
It prevents fire diffusion, be preferably minimized fire extinguishing difficulty, be beneficial to prevent secondary re-ignition.Particularly, first after fire generation
Time, the limited starting dry powder extinguishing installation of system implements quick extinguishing to transformer, when powder extinguishing system extinguishing chemical has sprayed
Cheng Hou restarts froth fire extinguishing system and sprays covering to by the protection implement fire foam, thoroughly put out, prevented with reaching fire
The purpose of fire re-ignition.
Specifically, interrupter 1 described in the present embodiment includes the frame being arranged in outside power transformer 4, Yi Jishe
Set fire screen or fire-proof plate in the frame.
The frame includes vertical bar 11 and cross bar 12, and the vertical bar 11 is plugged on the horizontal plane for placing power transformer 4；
The cross bar 12 is connected to two vertical bars far between horizontal one end.It is provided with spool on the cross bar 12 and drives the volume
The motor of axis rotation；One end of the fire screen or fire-proof plate connects on said reel；The control mechanism controls the electricity
Machine is forward or reverse.Thus can by fire-proof plate perhaps fire screen be rolled on spool or by fire-proof plate or fire screen from
Expansion is put down on spool.
In the present embodiment, the frame is cuboid, and the fire screen or fire-proof plate is respectively set in four sides, thereon
Surface is normally open face.In practical operation, upper surface can also be closed, stay a side as normally open, belong to this implementation
The simple replacement of example, repeats no more.
Finally, further including an oil draining nitrogen filling system 3 in the present embodiment, it is used for the oil inside power transformer 4 and divides
The fuel gas of solution is extracted out, and to injecting liquid nitrogen cooling inside power transformer 4.It, will be in transformer by oil draining nitrogen filling system 3
The oil in portion and the fuel gas discharge decomposed.Eliminate or reduce combustible leakage.
The preferable specific embodiment of the above, only the utility model, but the design concept of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, utilizes this design
The change that unsubstantiality is carried out to the utility model belongs to the behavior for invading scope of protection of the utility model.
