摘　　要：根据直流合成绝缘子电场分布特点 ,研制开发了轻便、可靠、有效的直流合成绝缘子带电检测仪 ,它通过测量合成绝缘子的纵向电场强度来判断直流合成绝缘子内导通性故障。实验室试验结果表明该检测仪能有效地检测出直流合成绝缘子内导通性故障且灵敏度较高。A convenient, reliable and efficient hot-line detector for DC composite insulators is developed according to its property of electric field distribution. The device distinguishes the internal conductive defect by detecting the longitudinal electric field intensity of the composite insulators. Lab test shows that the detector can efficaciously detect the internal conductive defect of DC composite insulators with quite high sensitivity.
