Research on Oil Temperature Control Method of Oil-immersed Transformer

对某110 kV油浸式变压器实际运行工况进行分析,同时对该变压器进行三维电磁仿真,获取变压器铁芯、绕组损耗及其分布。根据损耗随时间变化情况,采用一种补偿式控温方式有效调节变压器油温。

The actual operating conditions of a 110 kV oil-immersed transformer are analyzed.At the same time,the three-dimensional electromagnetic simulation of the transformer is carried out to obtain the core and winding losses and distribution of the transformer.According to the change of loss with time,a compensated temperature control method is adopted to effectively adjust the transformer oil temperature.
