不同周围流速和电压下的绝缘子积污特性

为了研究绝缘子在不同电压下表现的积污特性，利用流体力学的相关知识和电场理论，建立了模拟风沙的多物理场仿真模型.研究结果表明，周围流动速度较小时，绝缘子两端的电压增大，积污质量发会有一定程度的增加，且积污与电场力的变化密切相关，结合静电场分析会更准确；周围流动速度较大时，即使电压增大，积污质量也不会发生太大的变化.

Simulation of Insulator Contamination Characteristics Based on CFD

In order to study the contamination characteristics of insulator at different voltages, the wind flow field and electric field in sandstorm were simulated based on fluid mechanics theory and electric field theory. The research shows that contamination of insulator is different at different voltages. When the flow velocity around the insulator is small, the voltage at both ends of the insulator increases, which will lead to the increase of the contamination quantity, and the contamination is closely related to the change of electric field force. When the surrounding flow velocity is large, even if the voltage increases, the contamination quantity will not change too much.
