而對(duì)中間繼電器線圈軟故障還未有成熟的檢測(cè)方式，目前的現(xiàn)狀是：通過(guò)外接諧振電容利用諧振原理計(jì)算繼電器線圈在未投入使用前與使用一段時(shí)間后振蕩頻率變化，通過(guò)使用前后傳遞函數(shù)比值來(lái)判斷繼電器線圈絕緣老化缺點(diǎn)，對(duì)線圈進(jìn)行老化檢測(cè)；另一種方式是通過(guò)檢測(cè)直流電阻的變化來(lái)實(shí)現(xiàn)對(duì)線圈老化的檢測(cè)?，F(xiàn)有的檢測(cè)方法普遍比較復(fù)雜而且不能很好的實(shí)現(xiàn)對(duì)繼電器線圈軟故障的有效檢測(cè)。技術(shù)實(shí)現(xiàn)要素：針對(duì)現(xiàn)有繼電器線圈檢測(cè)方法復(fù)雜及不能有效檢測(cè)軟故障的問(wèn)題，本發(fā)明提供一種中間繼電器線圈軟故障檢測(cè)方法。本發(fā)明的一種中間繼電器線圈軟故障檢測(cè)方法，所述方法包括：s1、建立兩組數(shù)據(jù)樣本：a組和b組，a組為中間繼電器線圈正常的散射參數(shù)，b組為中間繼電器線圈軟故障后，得到的散射參數(shù)；s2、獲取待測(cè)中間繼電器線圈的散射參數(shù)，將該散射參數(shù)分別加入s1建立的a組和b組中，進(jìn)行聚類，若待測(cè)中間繼電器的散射參數(shù)與a組為一類，則確定待測(cè)中間繼電器正常，若待測(cè)中間繼電器的散射參數(shù)與b組為一類，則確定待測(cè)中間繼電器出現(xiàn)軟故障；所述散射參數(shù)包括相頻特性中相角為零對(duì)應(yīng)的頻率。作為推薦，所述s2還包括：當(dāng)確定待測(cè)中間繼電器線圈為軟故障。</p></p><br
