style="text-indent:25px">干式變壓器和油浸式變壓器的區(qū)別？油浸式變壓器是以油作為變壓器主要絕緣手段，依靠油作冷卻介質(zhì)（自冷。風(fēng)冷。水冷）。一般升壓站的主變都是油浸式的，變比20KV/500KV. 干式變壓器依靠空氣對流進(jìn)行冷卻。小容量變壓器變比6000V/400V. 干式變壓器和油式變壓器相比，除工作原理相同外，較大的區(qū)別就是變壓器內(nèi)部有沒有油，同時還有許多區(qū)別。從外觀上看，封裝形式不同，干式變壓器能直接看到鐵芯和線圈，而油式變壓器只能看到變壓器的外殼；引線形式不一樣，干式變壓器大多使用硅橡膠套管，而油式變壓器大部分使用瓷套管；</p><p

< 450 < 2501）壽命級的指標(biāo) 當(dāng)外部短路時，絕緣紙能夠承受的較大拉伸強(qiáng)度剩余率達(dá)到初始的 60%；危險級是指較大拉伸強(qiáng)度剩余率達(dá)到初始的 15%。油浸式變壓器設(shè)置要求。</p><p style="width:100%;text-align: center;"><img style="max-width:

style="text-indent:25px">油浸式變壓器，技術(shù)參數(shù)，額定容量：指變壓器正常運(yùn)行時所能承受的額定電壓。對于整流變壓器，為保證在規(guī)定時間內(nèi)將電壓提高到額定值，必須在空載時將電壓升到較高值；對于逆變變壓器，由于逆變過程中存在一定的損耗，使電壓升高的幅度受到限制，必須將電壓提高到額定值?？蛰d電流：指變壓器在空載時流過的電流，是計算空載損耗的依據(jù)。如果空載電流過大，將會造成變壓器局部過熱，甚至燒毀繞組。短路電流：指變壓器在短路時流過的電流，其值可通過繞組中產(chǎn)生的電動力進(jìn)行計算。允許連續(xù)工作時間：指變壓器在規(guī)定的負(fù)載下連續(xù)運(yùn)行一小時所能承受的最大負(fù)荷。對于逆變變壓器和整流變壓器，由于逆變過程中存在一定的損耗，所以連續(xù)工作時間一般不超過15分鐘。油浸式變壓器結(jié)構(gòu)圖展現(xiàn)。山東高性能油浸式變壓器容量</p><p
