摘　　要：绝缘子的污闪严重影响电力系统的安全运行,及时检测绝缘子的污秽程度可有效预防事故的发生。介绍了研制的基于微波辐射探测技术的绝缘子污秽带电检测仪,以及利用该检测仪对高压带电运行绝缘子的现场检测结果,并将检测结果与相应的等值盐密和等值灰密测量结果进行对比。初步的试验研究结果表明,所研制的绝缘子污秽检测装置可以用于高压带电绝缘子的污秽程度检测。Pollution flashover of insulator may seriously affect safe operation of power system and timely detection for degree of contamination of insulator is able to prevent accidents. Therefore, this paper introduces electric detector for contamina- ted insulator based on microwave radiation detection technology and locale detection for operational insulator with high volt- age electrification. It compares detection result with measuring results of corresponding equivalent salt deposit density and e- quivalent dust density. The preliminary testing and study result shows that this detection device for detecting contaminated insulator is applicable for detecting degree of contamination of high voltage electrified insulator.
