描述
FC-SDI-1624
電力變壓器在正常運行中其產(chǎn)生的電磁交流聲的頻率相對較為穩(wěn)定,所以電力變壓器在高壓試驗中如果操作人員發(fā)現(xiàn)其內(nèi)部聲音異常,則可能是電力變壓器過載運行、內(nèi)部零件松動、貼心最外層硅鋼片未夾緊、頂蓋螺絲松動、內(nèi)部電壓過高、內(nèi)部接觸不良以及電力變壓器短路等故障,或電力變壓器繞組中存在較大的電流等,上述多種情況都能導(dǎo)致電力變壓器高壓試驗中出現(xiàn)內(nèi)部聲音異常情況。上述故障發(fā)生后操作人員可以通過電力變壓器內(nèi)部聲音來判斷其是否出現(xiàn)故障,在判定故障發(fā)生后操作人員要對電力變壓器上述部位進行斷電檢查,并根據(jù)故障原因來采取合理的措施進行解決。電力變壓器在高壓試驗中如果出現(xiàn)自動跳閘的現(xiàn)象,則需要操作人員通過外部檢查來確定故障原因,如果是由于操作人員在高壓試驗中的操作原因?qū)е缕涮l,則不需要對電力變壓器進行外部檢查,但是如果不是認(rèn)為原因?qū)е码娏ψ儔浩魈l,則要求操作人員必須徹底、全面的對電力變壓器進行內(nèi)部檢查,避免電力變壓器在后期使用中發(fā)生火災(zāi)。如果電力變壓器周圍出現(xiàn)火災(zāi)則其會自動保護動作,通過自動切斷斷路器來避免電氣設(shè)備受到損毀,如果電力變壓器在火災(zāi)時沒有自動斷開,則要通過手動操作來將斷路器斷開才能進行火情撲救,這也是火災(zāi)情況下針對電力變壓器操作的主要前提條件。電力變壓器正常運行情況下的油位會控制在一定范圍內(nèi),并且根據(jù)當(dāng)?shù)鼐唧w情況來對油位進行適當(dāng)調(diào)整,所以在電力變壓器高壓試驗中如果發(fā)現(xiàn)油位明顯變化,要求操作人員首先要確定電力變壓器是否存在漏油現(xiàn)象,當(dāng)油位明顯上升時則首先要考慮是否環(huán)境溫度對其產(chǎn)生的影響。如果針對上述情況時可以排除掉環(huán)境溫度因素,則操作人員要對油標(biāo)管、呼吸管等部位進行檢查,確定其在運行中是否存在堵塞現(xiàn)象,并要根據(jù)實際檢查結(jié)構(gòu)來對其進行處理,這樣才能確保電力變壓器在后期使用中的安全性、穩(wěn)定性。
