摘要
35 k V主变微机差动保护动作,根据各种试验数据和二次查线进行分析,该变压器存在着隐患,决定吊芯检查,发现C相出现绕组匝间绝缘纸老化,该变压器退出运行。
The 35 k V main transformer has differential protection action, according to the test data and two time search line for analysis, the transformer has a hidden trouble, so decided to check the core and found that C phase in the winding turns of the insulation paper aging damaged, so this transformer was quit run.
