高压外绝缘设备的自然污秽特性的测试方法
摘要：
本发明实施例提供一种高压外绝缘设备的自然污秽特性的测试方法。该方法包括：获取高压外绝缘设备表面的待测试自然污秽；对待测试自然污秽进行等值盐密测试和灰密测试；对待测试自然污秽进行下述至少一种测试：污秽成分测试、污秽粒度测试、污秽形貌测试、污秽热重测试和污秽红外光谱测试。本方案通过对自然污秽进行等值盐密测试和灰密测试，能够确定污秽度；通过进行污秽成分测试、污秽粒度测试、污秽形貌测试、污秽热重测试和污秽红外光谱测试中至少一种测试，能够得到自然污秽所包含的离子和浓度、所包含颗粒的粒度、自然污秽的形貌特征、热稳定性、以及化学键信息或官能团信息中的至少一种，能够全面测试所述设备表面的自然污秽特性。
摘要（英）：

The invention discloses a method for testing natural pollution characteristics of a high-voltage external-insulation device. The method comprises the following steps of: acquiring to-be-tested natural pollution on the high-voltage external-insulation device; testing equivalent salt deposit density and dust density to the to-be-tested natural pollution; testing at least one of the to-be-tested natural pollution: pollution ingredient, pollution granularity, pollution morphology, pollution thermal weight and pollution infrared spectroscopy. In the scheme, the pollution level can be confirmed by testing equivalent salt deposit density and dust density of the natural pollution; at least one of ion, concentration, particle granularity, topographic characteristics, heat stability, chemical bond information or functional group information included in the natural pollution can be obtained by testing at least one of pollution ingredient, pollution granularity, pollution morphology, pollution thermal weight and pollution infrared spectroscopy, so that the natural pollution characteristics on the device surface can be comprehensively tested.
