造成变压器铁芯多点接地的原因及处理方法探讨

Discussion on the Causes of Transformer Core Multipoint Grounding and Treatment Methods

变压器如果出现铁芯多点接地,会严重影响其正常运行。探讨了造成变压器铁芯多点接地事故的主要原因,如铁芯绝缘老化、油纸绝缘老化、铁芯表面污染等。并针对性地提出相应的解决方案,包括更换绝缘材料、清除污染物、局部绝缘处理等。通过实践与改进,更好地理解了变压器铁芯多点接地的原因及处理方法,并且比较了不同方法的优缺点,为变压器维护和保养提供了新的思路,有力保障电力系统的稳定运行。

If the transformer is grounded at multiple points of core,it will seriously affect its normal operation.This paper discusses the main causes of transformer core multi-point grounding accidents,including core insulation aging,oil-paper insulation aging,core surface pollution and other factors that may lead to core multi-point grounding.And put forward corresponding solutions,including replacement of insulation materials,removal of pollutants,local insulation treatment,etc.Through practice and improvement,the reasons and treatment methods of transformer core multipoint grounding are better understood,and the advantages and disadvantages of different methods are compared,which provides new ideas for transformer maintenance and maintenance,and effectively guarantees the stable operation of the power system.
