摘　　要：对高压穿墙套管带电测试的几种方法进行简单的理论分析,对比了各种测试方法的优缺点,然后对一起带电测试方法发现异常数据的高压穿墙套管进行停电试验,分析了其故障原因,判断出存在绝缘缺陷,验证了带电测试的准确性,最后提出防范措施。Several methods of live test for high-voltage through-wall bushing are analyzed in simple theory, and the advantages and disadvantages of various test methods are compared. Then, a power-cut test for high-voltage through-wall bushing with abnormal data found by live test method is carried out, and its failure causes are analyzed by disintegration, insulation defects are judged,and live test is verified. The accuracy of the trial, and finally put forward preventive measures.
