摘要: 近年来，与静电放电(ESD)领域相关联的气体放电理论、材料科学和电测技术等新兴学科的不断研究和发展，已逐渐由实验科学阶段走向实际应用阶段。同时，人们也逐渐发现静电放电给人类造成的危害是十分惊人的，它不仅能够影响人类的正常生活，更是限制了自动化生产水平的提高。基于传统静电放电的模拟装置设备单一、功能局限，无法满足静电放电全方位、多用途的实验要求，为解决这一问题，设计和实现了包含电极模拟、方位变换、电路传输的完整的实验模拟装置。该装置主要由底座、支撑架、金属球、放电针、绝缘环、方位表盘等6部分组成，能够满足不同极化方向电磁场条件下的实验要求，同时还能够实现对不同高度、不同位置条件下的电磁场的基本极化方向进行判断识别。该系统具有一定的实验创新性和先进性，能够有效地满足各类电磁实验的需要，为研究电磁诱发静电放电实验提供了有力的硬件支持。Abstract: In recent years, the research and development of gas discharge theory, material science and electrical measurement technology, which are related to the field of electrostatic discharge (ESD), have gradually moved from the experimental stage to the practical stage. At the same time, people have gradually found that the harm caused by ESD to human beings is very alarming. It can not only affect the normal life of human beings, but also limit the improvement of automation production level. Based on traditional electrostatic discharge the simulator with single equipment and limited function, can not meet the all-round and multi-purpose experimental requirements of electrostatic discharge. To solve this problem, a complete experimental simulator including electrode simulation, azimuth conversion and circuit transmission was designed and implemented. The device is mainly composed of six parts: base, support frame, metal ball, discharge needle, insulating ring and azimuth dial. It can meet the experimental requirements of electromagnetic field in different polarization directions, and also can judge and identify the basic polarization direction of electromagnetic field in different altitudes and positions. The system is innovative and advanced, and provides powerful hardware support for the study of electromagnetic induced electrostatic discharge experiments.
