變電設(shè)備引起的故障
變壓器絕緣性能下降、氣體壓力升高。油浸式變壓器的絕緣油與空氣相接觸時,就會因吸濕、氧化等作用而使絕緣油性能變壞,使變壓器線圈的絕緣性能變壞,從而使整個變壓器的絕緣性能下降。為了防止上述情況的發(fā)生,對于大容量變壓器,可在其內(nèi)部密封氮氣,以防止絕緣油氧化。由于線圈的局部過熱和局部放電,以及鐵心的異常等原因,將會引起變壓器內(nèi)部的溫度上升。溫度的上升將引起絕緣油熱分解和氧化,進而產(chǎn)生異常氣體并溶解或滯留于絕緣油中。上述情況較輕時,氣體壓力將顯示異常;如果有異常發(fā)熱或短路等情況發(fā)生,則氣體壓力將急劇升高,可導(dǎo)致沖擊壓力繼電器動作。為了對上述來自變壓器內(nèi)部的故障實施保護,需要設(shè)置雙浮子繼電器。
