摘要
根据某水电站2台500 k V油浸式电力变压器及1台220 k V油浸式电力变压器本体介质损耗因数tanδ的测试数据,结合电介质介损的温度特性理论,综合分析变压器本体介损的温度特性与规程不符的可能原因。
Field tests are carried out to obtain the dielectric loss factor tanδ in the main bodies of two 500 kV and a 220 kV oil immersed power transformers in a hydropower station. According to the temperature characteristics theory of die- lectric loss, possible reasons of the difference between the actual temperature characteristics and the regulation are ana- lyzed.
