Found abnormal circuit resistance of ±800 kV DC wall bushing? in carrying out the preventive test of a converter station. It will pose a risk to equipment operate normally. This paper concludes assembly process is not rigorous, mechanical force and oxide layer of prolonged high load operation cause the abnormal circuit resistance of the DC wall bushing during describes the equipment, the test data and the disintegration situation of factory. Then put forward the follow-up? measures of operation and maintenance.
