摘　　要：针对双楼变电站1号主变压器套管例行试验中存在介质损耗因数超标的问题,从介质损耗因数增大原理、直流电阻试验数据和介质损耗数据三方面进行分析,认为套管介质损耗因数超标的原因是一次导电杆接触不良,并提出防范及判断该类主变压器套管介质损耗超标的建议。For the dielectric loss factor overproof problem of the No 1. transformer bushing of Shuanglou transformer sub-station in the routine test ,analyzes from the three respects that are the dielectric loss factor testing principle ,the DC re-sistance test data ,and the dielectric loss and so on ,considers that the cause is poor contact of conductive rod ,and puts for-ward the proposal about how to keep away and the sugges-tions to judge this kinds of transformer bushing dielectric loss factor .
