摘　　要：国际上涉及电力设备风沙环境试验模拟用沙漠粉尘未进行科学考证。为了解决该问题,采用X射线衍射仪等测试了沙漠地区绝缘子风沙积污物、沙尘暴粉尘以及沙漠表层沙粒样本。分析结果显示,绝缘子沙尘积污物的主要成分为石英、长石以及粘土成分,绝缘子积污物沙粒的粒径基本小于200μms,根据Al-Ca含量以及样本溶解率相关性分析的相关性分析,绝缘子沙尘积污物主要来源为沙漠沙尘暴沙尘和周围沙漠表层沙粒物。建议采用线路附近沙漠表层沙粒来模拟沙漠区域线路绝缘子和金具等电力设备的沙尘试验,但沙粒粒径需控制在200μms以下。No scientific research was conducted for simulation dust in desert environment test for electrical equipment internationally. To attack on the problem, series of test equipment are used to measure insulator sand sediment, storm dust and surface sand samples of insulators in desert areas. The analysis showed that the main components of insulator dust accumulations include quartz, feldspar, and clay composition, and grain diameters of dust is <200 μms. Based on correlation analysis of Al-Ca content, soluble matter solubility, the main sources of insulator dust accumulation are desert dust and sand particles on the surface of the surrounding desert. Surface sands of the surrounding desert are suggested to simulate desert environment test for insulators and fittings, but the sand particle size should be controlled <200 μms.
