Description
Technical Field
The invention relates to the technical field of fire prevention and disaster prevention of converter stations, in particular to a plugging structure of a converter valve hall valve side sleeve.
Background
The fire hazard of the converter station is often not the converter valve itself, but other equipment in the converter station catches fire, such as: when the converter transformer short circuit is in fire, the local temperature reaches the ignition point of the insulating oil, the deflagration phenomenon is generated continuously for a period of time, a huge impact force is formed, the fire behavior enters a converter valve hall through the converter transformer and the valve hall plugging position, the valve hall is caused to fire in a large area, and huge loss is caused.
The insulating oil can cause hydrocarbon fire when reaching the ignition point, and compared with the combustion of cellulose, the combustion of the hydrocarbon fire has the characteristics of quick explosion and high temperature, can reach 1100 ℃ in a very short time, and easily causes the quick attenuation of the performance of the fireproof plugging material; meanwhile, the existing fireproof blocking scheme does not solve the blocking problem from the system level, mainly focuses on the selection of a main body blocking material, does not fully consider weak links such as edge connecting parts, large and small blocking seams and the like of the blocking system, and has extremely high fire spreading risk. The plugging of the converter transformer and the valve hall is the key of fire prevention and self rescue, which is directly related to the safety of a large amount of equipment, and the plugging of the converter transformer valve of the converter station as a special area of a transformer substation puts higher requirements on the fire resistance limit of plugging materials.

The material is usually selected from a structural rock wool composite fireproof plate or a combination of a structural rock wool plate and a profiled galvanized steel plate composite plugging material. Although the fire-proof limit of the plate material of most of the fire-proof plates made of the structural rock wool composite fire-proof plate is usually more than 3 hours, the performance of a fire-proof sealing system made of the adopted fire-proof plates is poor, so that a high fire spreading risk exists. In order to facilitate transportation and improve construction efficiency, the cotton plate adopted by the existing structural rock wool plate and profiled galvanized steel plate composite plugging material has low density, the strength support of the cotton plate is totally supported by the profiled galvanized steel plates with the thickness of 0.5-5 mm on both sides, and the converter station is ignited to generate deflagration phenomenon, so that huge impact force can be formed, the plugging system is easy to crack, and the protective performance is lost.
