摘　　要：采用静电电压表、电导率仪，通过试验，对泡沫冲击油品过程中的静电特性进行研究。油品的液面高度为500mm，泡沫混合液的流速分别为1．5、3．0m／s，对比分析不同泡沫、不同浓度下冲击油品过程中的静电电位。选取水成膜6％泡沫，对比分析1．0～4．0m／s流速下冲击油品过程中的静电风险。检测装油过程中的液面电位，最高为450V。电导率检测结果表明，使用消防泡沫后，部分泡沫会以杂质的形式出现在油品内，增大了油品静电起电的概率。对泡沫冲击油品过程中的静电风险进行理论分析，为消防泡沫的安全使用提供参考。The electrostatic voltmeter and the conductivity meter were used to test the electrostatic characteristics during the im- pact of foam onto the surface of oil. The height of oil was 500 mm and the velocity of foam mixture was 1. 5 and 3. 0 m/s. The electrostatic potential under different foam with different concentration was analyzed. The electrostatic risk was tested used 6% AFFF foam under velocity of 1.0-1.4 m/s. Thehighest surface potential during the oil loading was tested to be 450 V. The results of electronic conductivity test showed that after the usage of firefighting foam, the probability of electrifi- cation of oil increased due to the foam in the oil as impurity. The electrostatic risk of oil during the impact of foam was ana lyzed theoretically to provide reference for safety use of fire- fighting foam.
