摘要
针对火炸药生产、存储、运输以及使用过程中的静电放电问题,为了寻找抑制静电放电电压过高的可行办法,对空气、二氧化碳、氦气在0、20、40℃3种温度条件下以及压强范围0.05~0.15 MPa之间的静电击穿特性展开研究,并计算对比了静电击穿能量。结果表明:随着气压的升高,3种气体的静电击穿电压随之升高,其中二氧化碳的静电放电电压在相同条件下最高,静电放电能量最大,氦气放电电压在3种气体中最低;随着温度的升高,3种气体的静电击穿电压随之下降,在40℃、0.05 MPa下,3种气体静电击穿电压达到最小,因此应选择低压、较高温度、低击穿场强气体的环境作为静电防护气氛环境。本文的研究结果可为火炸药生产过程中保护气氛环境的选择提供数据基础和理论支撑。
Aiming at the problem of electrostatic discharge in the process of production,storage,transportation and use of explosives,the electrostatic breakdown characteristics of air,carbon dioxide and helium under three temperature conditions of 0,20,40℃and the pressure range between 0.05 and 0.15 MPa are studied to find a feasible way to suppress the excessively high electrostatic discharge voltage,and the electrostatic breakdown energy is calculated and compared.The results show that the electrostatic breakdown voltage of the three gases increases with the increase of the pressure.The electrostatic discharge voltage and energy of carbon dioxide are the highest under the same condition,while the discharge voltage of helium is the lowest among the three gases;with the increase of temperature,the electrostatic breakdown voltage of the three gases decreases,and the electrostatic breakdown voltage of the three gases reaches the minimum at 40℃and 0.05 MPa.Therefore,an environment with low pressure,higher temperature,and low breakdown field strength should be selected as the electrostatic protection atmosphere environment.These research results may serve as data basis and theoretical support for selection of protective atmosphere environment in the production process of explosives.
