基于相角差的绝缘子表面污秽受潮检测系统设计与仿真

摘要

为实时检测污秽受潮状态，防止绝缘子表面污秽受潮引发污闪事故，本文设计了基于相角差的绝缘子表面污秽受潮状态检测系统，并利用电路仿真软件M ultisim12对系统测量电路及各功能模块进行了仿真。仿真结果表明，该系统能够实现检测绝缘子表面污秽受潮状态。%In order to achieve real‐time detection of contamination wetting state to prevent the pollution flashover caused by the insulator surface contaminating wetting ,the wetting state de‐tection system of insulator surface contamination is designed based on phase angle difference , the measuring circuit and various parts of system with the powerful circuit simulation software Multisim 12 are used to conduct the simulation .According to the simulation results ,the sys‐tem can detect the wetting state of the insulator surface surface contamination .
