%X 为更好的实现气体组分分析法在中高压开关柜绝缘状态预测评估这一领域的应用，本文对典型有机绝缘材料(环氧树脂、硅橡胶、SMC)电痕化过程气体释放规律进行研究。选取非甲烷总烃、氢气、一氧化碳作为监测目标物，重点研究典型有机绝缘材料经过不同温、湿度处理后，在电痕化过程中目标气体浓度变化规律。典型有机绝缘材料环氧树脂、硅橡胶、SMC电痕化过程会产生非甲烷总烃(NMHC)、氢气、一氧化碳气体，且在电痕化过程中生成气体浓度为氢气 &gt; 非甲烷总烃(NMHC) &gt; 一氧化碳；典型有机绝缘材料环氧树脂、硅橡胶、SMC在预处理条件温度(25℃~150℃)、湿度(50%~98%)变化范围内，电痕化过程中气体释放量与样条预处理的温度和湿度呈正相关的关系，即预处理温度越高、湿度越大，电痕化过程中气体释放量越大；在预处理条件温度(25℃~150℃)、湿度(50%~98%)变化范围内，典型有机绝缘材料环氧树脂、硅橡胶、SMC的耐电痕性能与温、湿度不构成简单的正相关或负相关关系，需要进一步进行重点研究。<br />
In order to better realize the application of gas component analysis method in the field of insula-tion state prediction and evaluation of medium and high voltage switchgear, this paper studies the gas release law of typical organic insulating materials (epoxy resin, silicone rubber, SMC) during electrical tracking process. Non-methane total hydrocarbon, hydrogen and carbon monoxide were selected as monitoring targets, focusing on the study of the concentration changes of target gas in the process of electrical tracking after typical organic insulating materials were treated with different temperature and humidity. Typical organic insulating materials such as epoxy resin, silicone rubber and SMC electrical tracking process will produce non-methane total hydrocarbon (NMHC), hydrogen and carbon monoxide gas, and the gas concentration is hydrogen &gt; non-methane total hydrocarbon (NMHC) &gt; carbon monoxide. In the range of temperature (25？C~150？C) and humidity (50%~98%) of the pretreatment conditions, the gas release in the process of electric tracing is positively correlated with the temperature and humidity of the spline pretreatment, that is, the higher the temperature and humidity of the pretreatment, the greater the gas release in the process of electric tracking. In the range of temperature (25？C~150？C) and humidity (50%~98%) under pretreatment conditions, the electric tracking resistance of typical organic insulating materials such as epoxy resin, silicone rubber and SMC does not form a simple positive or negative correlation with temperature and humidity, which requires further focus research.
