Description
Technical field
The invention belongs to transformer station's fire fighting device is and in particular to a kind of main fransformer oil explosive fire accident fire extinguishing system pipe network is prevented
Quick-fried device arranges technology.
Background technology
For a long time, the main transformer fire protection design of transformer station's nucleus equipment primarily focuses on putting down between each main transformer
Face arrangement is equipped with fire wall and is required with meeting the fire-protection distance that fire protection rule specifies, in transformer profile 10～1.5m scope
Setting transformer oil pond, draining transformer oil when there is fire, meanwhile, arranging water spray, bubble jet outside transformer body
The fire extinguishing systems such as mist, dry powder, note nitrogen are put out a fire.
58 points during 4 days 2 October in 1978, Jiangsu Province Zhenjiang areas power plant 5 120,000 thousand volt-ampere transformers occur tight
Restart fiery explosion accident, transformer oil is ejected into around outside oil sump in a large number, cause dead 3 people of worker overhauling, hinder 12 people,
800,000 yuan of property loss；On June 25th, 2009 5:00 AM, Wuhan Qingshan District 500kV Zhang Jiapu transformer station 1# main transformer A phase occurs
Moderate explosive fire accident, transformer oil is ejected near oil sump and causes large area fire, and fire brigade adopts 6 hydraulic giants after more than two
Hour, stamp out a fire within 18 minutes at 7 points；In 16 minutes 17 points of on Mays 19th, 2010, nearby 500kV transformer station becomes Laibin, Guangxi Province B power plant
There is top high-voltage sleeve pipe moderate explosive fire accident in depressor, flare rises meter high about more than 20, and the change of sleeve pipe side is arrived in transformer oil splash
Cause large area fire outside depressor oil sump, fire extinguishing system failure in a long time, 18 points 06 minute, nearby fire brigade's fire fighting truck reach the spot,
19 points 16 minutes, last more than about 1 hour through fire brigade and put out a fire to save life and property, successfully stamp out a fire；On July 22nd, 2015, certain city 500kV becomes
Power station 1# main transformer A phase 250MVA transformer high-voltage bushing and liter dais explode, and cause transformer high-voltage bushing and rise dais
All blown up, the transformer part blown up has smashed transformer water atomizing fire extinguishing system pipe network simultaneously, causes water spray extinguishing
Thrashing, a large amount of transformer oil are risen dais from bushing and are sprayed with the junction of device body, wherein, account for this single-phase change always oil
The transformer oil of amount 60% drains into main emergency oil pool along accident oil draining system, about 20% transformer oil then splash to adjacent
On (1# main transformer B phase, 2# main transformer C phase) transformer, main transformer place, main transformer fire wall, leader cable ditch, 500kV power distribution equipment place
And on main transformer transport routes, remaining about 20% transformer oil is deposited in device body, because the temperature of oil in transformer that splash goes out is far high
In self-ignition point temperature, define large area transformer oil working fire, continue fire in transformer oil splash scope after meeting air
With resume combustion fire.22 points of 22 days fire for transformer time 1:00 AM, 2 o'clock arrival transformer station of fire brigade scene of fire, 2: 25
The load transfer of point transformer station finishes, and 1#, 2# main transformer fully enters cold standby, and fire brigade starts to put out a fire, 2 points 55 minutes, transformer and
Surrounding place naked light puts out, the whole fire suppression of 5 o'clock of morning, and afterwards, fire transformer oil burns totally substantially, and fire brigade adopts
After fire fighting truck water fire-fighting, a small amount of transformer oil drains into outside station through road and yard drain system, causes ambient contamination.
From fire cases above, when there is moderate explosive fire accident in transformer, bushing shell for transformer and sleeve pipe
Rise dais and only burst oil spout, when there is serious explosive fire accident, the part such as bushing shell for transformer and liter dais all can be pounded by blowing up
Destroy fiery system pipe network, cause fire extinguishing system to lose efficacy, therefore, in order to ensure transformer fire extinguishing system normal using it is necessary to
Perfect Explosion of Transformer fire extinguishing system pipe network explosion-protection equipment is set.
