摘要
目前大部分变压器套管末屏接地方式是弹簧自动复位式,若其不能正常复位,会导致末屏接地不良。当变压器运行后,套管末屏对地放电,长期对地放电会引起绝缘击穿,导致套管损坏,甚至可能引起变压器失压,造成严重的经济损失,所以必须检测变压器套管末屏接地情况。
At present most of the transformers employ bushing tap grounding with automatic reset by spring.If it reset abnormally,tap grounding will be unstable.Bushing tap discharge to ground.since the transformer has been put into opration.A long-term discharge to detection of bushing tap grounding situation of transformer is of the essence.
