Description
Technical field
The invention belongs to substation's fire fighting devices, and in particular to a kind of side casing transformer oil guard fire prevention protection skill
Art.
Background technology
For a long time, the main transformer fire protection design of substation's core equipment is mainly taken according to specification in each main transformer
Firebreak, fire wall, main transformer shape 1.0~1.5m ranges setting transformer oil storage, oil storage row are set between depressor
Oil-piping, main emergency oil pool etc. are analyzed from fire cases, and the store oil of specification setting at present, oil extraction, fireproofing installation at most can only
Meet some transformers oil measure oil after the casing Explosion of Transformer of top, oil extraction, fire protection requirement, but side casing cannot be met
Transformer fire protection requirement.
On July 22nd, 2015, the 1# main transformer A phase 250MVA transformations of city of Yunnan Province 500kV transformer substation sides face sleeve structure
Serious explosion occurs for device bushing and raising seat, and transformer high-voltage bushing and raising seat are all blown up, the transformer blown up
Component has smashed transformer water atomizing fire extinguishing system pipe network simultaneously, and water spray fire extinguishing system is caused to fail, farthest transformer portion
Part flies out over transformer 50m, is just fallen on the ground after encountering 500kV electrical room exterior walls, a large amount of transformer oil after explosion
The junction that seat and device body are increased from bushing sprays, and splash range is more than 40~50m, if separated without fire wall, week
It encloses transformer and is likely occurred working fire.Ex-post analysis, about 10~20% transformation in the transformer oil of accident transformer
In device oil splash to adjacent (1# main transformer B phases, 2# main transformer C phases) transformer, main transformer place, main transformer fire wall, leader cable ditch,
On 500kV power distribution equipments place and main transformer transport routes, 60~70% transformer oil is quick from transformer side surface cover tube opening
Trickling comes out, and some transformers oil stream has arrived the transformer place outside transformer oil storage, on main transformer transport routes, part transformation
Device oil drains into main emergency oil pool along accident oil draining system, and the transformer oil of residue about 15~20% is deposited in device body, due to spray
Splash the temperature of oil in transformer that trickles and be far above self-ignition point temperature, meet form after air large area transformer oil working fire,
Continue fire and resume combustion fire.22 days accident fire for transformer time 1:00 AM 22 divides, and 2 o'clock, fire brigade reached substation's fire
Calamity scene, 2 points of substation's load transfers in 25 minutes finish, and 1#, 2# main transformer fully enter cold standby, and fire brigade starts to put out a fire, and 2: 55
Point, accident transformer and surrounding place open fire are put out, the whole fire suppression of 5 o'clock of morning, 40 points of fire duration 4 hours
Clock, attack time 2 hours, afterwards, fire transformer oil burn totally substantially, after fire brigade uses fire fighting truck water fire-fighting, on a small quantity
Trickling transformer oil is drained into through road and yard drain system outside station, causes ambient enviroment water pollution.
By fire cases above as it can be seen that side casing Explosion of Transformer fire is a kind of common in transformer fire
Fire type when serious explosive fire accident especially occurs, since the components such as transformer side surface cover pipe and raising seat are blown up, sprays
The transformer oil oil mass for splashing trickling has been more than the 80% of the total oil mass of transformer, wherein accounts for the spray of 10~20% transformer oil of total oil mass
It splashes range and reaches 40~50m, if protected without Auxiliary Transformer Firewall, transformer fire sprawling around, therefore, transformation will be caused
Device fire wall is that side casing transformer fire is prevented fires essential component, and transformer oil splash in order to prevent, is also wanted
Take antispray measure；The trickling of 60~70% transformer oil of total oil mass is accounted for have arrived the oil storage of transformer side surface cover pipe side, become
On depressor place and main transformer transport routes, transformer oil storage and oil draining system protection domain are had exceeded, large area splash is caused
Spill fire not only causes transformer fire extinguishing system to fail, also adds fire extinguishing difficulty, fire duration 40 minutes 4 hours,
Attack time 2 hours, it is prolonged to put out a fire, cause a large amount of air pollution；And after fire brigade is using the fire extinguishing of water fire fighting device,
It is heavily contaminated that trickling transformer oil also creates substation's surrounding water；Certain areas use the change of side casing transformer
Power station quantity is more, and some of substations are also located in water conservation district, reservoir, scenic spot periphery, once above-mentioned explosion occurs
Fire, loss will be unable to estimate.In order to carry out side casing transformer oil splash and trickling protection fire prevention, reduce air pollution and
Water pollution, it is necessary to which transformer side surface cover pipe oil guard is set.
