Transformer fire extinguishing device evaluation method

Abstract

The invention discloses a transformer fire extinguishing device evaluation method. The method comprises the steps of obtaining state quantity data of a transformer fire extinguishing device; inputting the obtained data of each state quantity into a processor to obtain a membership degree vector corresponding to each state quantity; forming a state quantity importance degree matrix according to the importance level scale stored in the first database; on the basis of the state quantity importance degree matrix, obtaining a weight vector, and calculating to obtain an initial score value of the transformer fire extinguishing device; acquiring a transformer fire risk evaluation value, matching the transformer fire risk evaluation value with a deduction value stored in a second database, and acquiring a deduction value corresponding to the evaluation value; adding the initial score value and the deducted score value to obtain a comprehensive score of the transformer fire extinguishing device considering the transformer fire risk; and evaluating the performance of the transformer fire extinguishing device according to the comprehensive score. The transformer fire extinguishing device is comprehensively evaluated, the fire extinguishing efficiency of the transformer fire extinguishing device can be effectively improved, and disaster loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of fire fighting equipment, and in particular relates to an evaluation method for a transformer fire extinguishing device. Background technique [0002] Transformer is one of the key equipment in power transmission. The state of transformer not only affects its own safe operation, but also affects the stability and reliability of power system operation. When a transformer fails, the huge arc energy may cause a fire. Recently, a converter station caught fire due to a failure of the grid-side oil-paper insulating bushing, and the fire spread from the converter body to the valve hall, causing the entire valve hall to collapse, causing 6 sets of converter transformers, converter valves and other equipment in the same valve hall to catch fire; In a converter station, the bushing on the side of the converter substation was faulty and caught fire, and the converter substation was on fire; in a converter station, t...

When the transformer fails, the huge arc energy may cause a fire

Recently, a converter station caught fire due to a failure of the grid-side oil-paper insulating bushing, and the fire spread from the converter body to the valve hall, causing the entire valve hall to collapse, causing 6 sets of converter transformers, converter valves and other equipment in the same valve hall to catch fire; The bushing on the side of the converter substation in a converter station caught fire due to a fault in the converter substation; a fire occurred in the converter substation in a converter station due to a fault in the HD converter substation

There is a greater risk of fire in the converter substation, and a fire in the converter substation will cause the DC system to stop operating, directly resulting in huge economic losses

[0003] At this stage, the evaluation method of transformer fire extinguishing device is not comprehensive enough, the risk of transformer fire is not considered comprehensively, and the transformer is not distinguished between flammable and flame retardant

This may lead to insufficient maintenance and repair of the transformer fire extinguishing device, which will increase the difficulty of extinguishing fires and expand the losses caused by fires.
