摘要
为了更好的研究静电放电机理,开发了一种模拟静电荷集聚和消散过程的实验系统(专利号:ZL 2023 1 0005367.1);通过试验发现,温湿度对于静电荷的消散过程影响显著.在静电放电测试标准IEC 61000-4-2 规定的试验温湿度范围内,不同温湿度对应的静电荷消散曲线差异很大,这很有可能损害静电放电试验结果的可重复性以及可复现性.通过实验数据,并结合前期工作已确认的只有温度对最大击穿距离影响较大的结论,本工作建议调整温湿度条件以提高静电放电试验结果的可重复性和可复现性,并给出推荐的温湿度范围.
Abstract
To study electrostatic discharge mechanisms,a novel experimental system was developed to simulate the accumulation and dissipation process of electrostatic charge(Chinese patent No.ZL 2023 1 0005367.1).It has been observed that temperature and humidity play an important role during static charge dissipation processes.Within the specified test range outlined in electrostatic discharge test standard IEC 61000-4-2,the dissipation curves for electrostatic charge corresponding to different temperature and humidity levels exhibit notable variations,potentially compromising the repeatability and reproducibility of electrostatic discharge test results.Based on the experimental data and the conclusion confirmed by the previous work that only temperature has a great influence on the maximum breakdown distance,it is recommended to adjust temperature and humidity conditions in order to improve repeatability and reproducibility of electrostatic discharge test results,with a specific recommended range provided.
