摘　　要：为推进新型环保绝缘气体开发工作,对单一气体、混合气体的绝缘强度经验和半经验预测模型进行了分析。对于经验模型,分子微观参数的优选是关键。相互作用性质函数(general interaction properties function,GIPF)和基团贡献法的引入可提高模型准确性。在使用上述参数时需要从气体放电的角度出发,对参数适用性进行判断,并尝试寻找或定义出气体绝缘领域的特殊分子微观参数。此外,所用气体放电数据需要标准化处理,并在统一的测试条件下对各类气体的绝缘强度进行评估,进而减少样本质量对模型误差的影响。在气体放电理论研究尚不完备的前提下,经验、半经验模型仍需要配合使用。而对于混合气体预测模型,其主要难点在于协同效应的量化定义和预测,这可能与分子间相互作用等微观过程有关。而在完备气体放电理论指导下建立的预测模型可具有更高的准确性和通用性,并可进一步提高环保绝缘气体的开发效率。In order to promote the development of new eco-friendly insulation gases,the development of empirical and semi-empirical models for dielectric strength prediction of single and mixed gases were analyzed.The selection of molecular parameters is the basis of the empirical models.The introduction of the general interaction property function(GIPF)and the group contribution method can improve the accuracy of model.It is necessary to judge the applicability of the above-mentioned molecular parameters from the perspective of gas discharge so as to try to find or define particular parameters in the field of gas insulation.In addition,the gas discharge data should be standardized.The insulation strength of various gases should be evaluated under uniform test conditions,thereby the effect of sample quality on model error can be reduced.Due to the insufficient theoretical investigations on discharge,the empirical models should be used in conjunction with semi-empirical models.As for the mixed gas prediction model,the main difficulty lies in the prediction of synergistic effects,which may be related to the process of molecular interactions.The prediction model guided by the complete gas discharge theory may have higher accuracy and generality,which can further improve the efficiency of developing eco-friendly insulation gases.
