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。

Abstract

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

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.
