摘要
高压变压器油/气套管是一种新型电气设备,由于结构特殊,现场试验需要打开SF6气室,工作难度大。为了在不打开SF6气室情况下,对高压变压器油/气套管进行介质损耗试验,笔者结合电路分析和试验,提出了一种新的中性点加压试验方法,并在现场设备上进行实际应用,对试验接线可能引起的误差及测量结果等进行了分析和比较,证明分析和试验结果有很好的一致性,新的试验方法方便可行。
Oil/SF6 gas insulated high voltage bushing is a new type of electric equipment in transformer. Because of its special structure, it is very difficult to open the SF6 gas chamber in field test. This paper presents a new test method for dielectric loss of the bushing, in which the chamber needn＇t be opened. A test circuit with a voltage on the neutral point is designed and applied to field test device. The test data and the possible error are analyzed. Field test shows that the test data is consistent with the analytical one.
