中小型凸极式发电机磁极接头的连接,多采用铆接和并头套加锡焊的方法。运行机组在正常情况下,转子受电磁力的作用;在非常情况下(非同期合闸),它又受机械振荡力的影响,往往使一些接头发生变形或脱焊、氧化等现象。于是,接头发热,引起事故。凡接头事故,不论出自何种原因,接触 Small and medium salient pole generator pole connector connection, and more use of riveting and header sleeve plus soldering methods. Under normal conditions, the rotor is affected by the electromagnetic force. In the very case (non-synchronous closing), it is affected by the mechanical oscillation force and often causes some joints to deform, desolder, and oxidize. Thus, the connector fever, causing accidents. Where joint accident, no matter what kind of reason, contact
