摘　　要：通过油/气套管和GIS连接的电力变压器是一种新型结构电力设备。对其进行介质损耗和电容测量试验,需要将SF6气室打开才能进行试验接线,现场处理难度大,并且容易在处理过程引起新的设备缺陷。文中介绍不打开SF6气室,对变压器进行介质损耗和电容测量的试验方法。理论分析和现场试验证明,该试验方法简单,测试数据可靠。Transformer with oil/gas Insulated bushing is a new kind of electric equipment. Because of its special structure, SF6 gas chamber needs to be opened for wire connection during dielectric loss and capacitance measurement tests. A new measurement method no need to open SF6 gas chamber was introduced in this article. It was proved by theory analysis and practical tests that the new test method is simple and feasible.
