干式變壓器通電運行后，我們應該如何的維護，來保證干式變壓器的長期穩定的運行呢?今天讓我們來分享幾個注意事項：

　　1、配電(dian)干式變壓器接地電(dian)阻的(de)定期測(ce)量

　　長期運行(xing)(特別是(shi)接地(di)(di)(di)線(xian)用(yong)鋁線(xian)代替(ti))后，配(pei)電(dian)(dian)(dian)干式變(bian)(bian)壓(ya)(ya)器氧化(hua)嚴重(zhong)，接地(di)(di)(di)電(dian)(dian)(dian)阻增(zeng)大，填埋地(di)(di)(di)體生銹被(bei)破壞，中性點電(dian)(dian)(dian)位(wei)轉移。一旦有雷擊或過電(dian)(dian)(dian)壓(ya)(ya)，就容易發生事故(gu)。根據規定(ding)，接地(di)(di)(di)裝(zhuang)置應(ying)滿足以下(xia)要(yao)求。100 kVA以下(xia)配(pei)電(dian)(dian)(dian)干式變(bian)(bian)壓(ya)(ya)器的接地(di)(di)(di)電(dian)(dian)(dian)阻不(bu)超過10Ω，100 kVA以上(shang)的配(pei)電(dian)(dian)(dian)干式變(bian)(bian)壓(ya)(ya)器的接地(di)(di)(di)電(dian)(dian)(dian)阻不(bu)超過4Ω。

　　2、加(jia)強日常管(guan)理(li)

　　定期巡(xun)邏，砍樹，防止樹枝碰線的(de)低壓(ya)(ya)短路燒(shao)毀(hui)配電(dian)(dian)干(gan)式(shi)變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)。配電(dian)(dian)干(gan)式(shi)變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)缺乏日常的(de)管理。由于長(chang)期性的(de)油(you)不足運行著。沒有及時(shi)安裝呼吸器(qi)(qi)或更換硅膠。使配電(dian)(dian)干(gan)式(shi)變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)潮濕，容(rong)易(yi)發生事(shi)故。配電(dian)(dian)干(gan)式(shi)變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)本身就有質量問題(ti)。由于配電(dian)(dian)干(gan)式(shi)變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)的(de)設置位置較(jiao)遠(yuan)，一部分施工者隨意將(jiang)無試驗配電(dian)(dian)干(gan)式(shi)變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)投入(ru)駕駛中，臨時(shi)使用電(dian)(dian)，燒(shao)壞(huai)干(gan)式(shi)變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)。

　　3、定期檢(jian)查配電干式變壓器(qi)的低壓引導

　　用引線(xian)做(zuo)鼻子，嚴禁直接上配(pei)電干(gan)式(shi)變(bian)壓(ya)(ya)器的(de)低壓(ya)(ya)管道(dao)。定期檢查，確認配(pei)電干(gan)式(shi)變(bian)壓(ya)(ya)器的(de)編碼(ma)和(he)樁(zhuang)的(de)接觸，防(fang)止配(pei)電干(gan)式(shi)變(bian)壓(ya)(ya)器的(de)低壓(ya)(ya)樁(zhuang)的(de)松動和(he)燒損。為(wei)(wei)保證配(pei)電干(gan)式(shi)變(bian)壓(ya)(ya)器的(de)長期安全運行，減少故障次(ci)數，作為(wei)(wei)運行管理者，要經常清點、保持、測量、發現問題、及時處理，避免配(pei)電干(gan)式(shi)變(bian)壓(ya)(ya)器的(de)膨脹導致的(de)錯誤燒毀。
