适用于变压器油火的泡沫灭火剂评价指标体系与方法

Evaluation Index System and Method of Foam Fire Extinguishing Agent Suitable for Transformer Oil Fire

随着变压器数量不断增加,其内部变压器油的消防安全问题日益严峻。水成膜泡沫灭火剂虽然能够有效抑制油类火灾,但在应对不同条件火场时其灭火性能的差别较大。为了优选出适用于变压器油火的泡沫灭火剂,首先建立了适用于变压器油火的泡沫灭火剂灭火性能评价指标体系;然后,基于现有文献和试验数据,制定各评价指标的取值标准;最后,以该评价指标体系为基础,采用模糊熵权法对适用于变压器油火的10种泡沫灭火剂的灭火性能进行了评价,并优选其中5种泡沫灭火剂进行了变压器油火抑制试验验证。结果表明:适用于变压器油火的泡沫灭火剂灭火性能评价指标体系的评价结果与变压器油火抑制试验结果的一致性较高,说明该评价指标体系能够区分不同泡沫灭火剂对变压器油火的灭火性能,对泡沫灭火剂的筛选具有一定的参考价值。

With the increase in the number of transformers,the internal transformer oil fire protection is severe.Although aqueous film forming foam extinguishing agent is an effective way to suppress oil fire,its performance varies greatly in suppressing fires under different conditions.In order to select the most sui-table foam fire extinguishing agent for transformer oil fire,this research firstly establishes a targeted eva-luation index system suitable for transformer oil fire,and formulates the value standard of each index based on the literature and experimental data.Then,based on the index system,the research evaluates the suitability of 10 kinds of foam extinguishing agents using the fuzzy entropy weight method.Finally,the research selects 5 kinds of foam extinguishing agents for transformer oil fire suppression experiment verification.The results show that the evaluation results of the fire extinguishing performance index system are consis-tent with the transformer oil fire suppression experiment.In summary,the index system can screen out foam extinguishing agents suitable for transformer oil fire,which has reference significance.
