style="text-indent:25px">變壓器滲漏油的原因分析：1、橡膠密封件失效和焊縫開裂變壓器的焊點(diǎn)多、焊縫長(zhǎng)，而油浸式變壓器是以鋼板焊接殼體為基礎(chǔ)的多種焊接和連接的體。一臺(tái)31500kVA變壓器的總焊點(diǎn)達(dá)70余處，焊縫總長(zhǎng)近20m左右，因此滲漏途徑可能較多。直接滲漏的原因是橡膠密封件失效和焊縫開裂、氣孔、夾渣等。2、密封膠件老化、龜裂、變形變壓器滲漏多發(fā)生在連接處，而95 %以上主要是由密封膠件引起的。密封膠件質(zhì)量的好壞主要取決于它的耐油性能，耐油性能較差的，老化速度就較快，特別是在高溫下，其老化速度就更快，極易引起密封件老化、龜裂，變質(zhì)、變形，以至失效，造成變壓器滲漏油。遼寧電子變壓器在線監(jiān)測(cè)系統(tǒng)測(cè)試過(guò)程中禁止觸摸被測(cè)試變壓器接線銅牌。</p><div

2、采用高頻開關(guān)電源技術(shù)，輸出電流大，適合大中型變壓器直流電阻測(cè)量。 3、保護(hù)功能完善，能可靠保護(hù)反電勢(shì)對(duì)儀器的沖擊，性能更可靠。 4、具有聲響放電報(bào)警，放電指示清晰，減少誤操作。 5、響應(yīng)速度快，可在測(cè)量狀態(tài)直接轉(zhuǎn)換有載分接開關(guān)，儀器自動(dòng)刷新數(shù)據(jù)6、采用立式機(jī)箱結(jié)構(gòu)，便于現(xiàn)場(chǎng)使用。 7、智能化功率管理技術(shù)，儀器總是工作在較小功率狀態(tài)，有效減輕儀器內(nèi)部發(fā)熱，節(jié)約能源。

連接并聯(lián)支路的一端，測(cè)量各同名端的電勢(shì)差，其電勢(shì)差應(yīng)等于零；為了避免由于回路接觸不良造成電勢(shì)差為零，允許在測(cè)量中加入一匝，使電勢(shì)差為1V；臨時(shí)匝應(yīng)分別正繞與反繞串入回路，其電勢(shì)差均應(yīng)近似等于1V； (3) 為了避免因增加串聯(lián)匝數(shù)而使電勢(shì)差減小的現(xiàn)象，測(cè)量電勢(shì)差的電壓表應(yīng)盡量采用高內(nèi)阻的電壓表； (4) 電勢(shì)差試驗(yàn)時(shí)被試?yán)@組的電壓雖然只有1V，但其電位往往很高；在并聯(lián)支路中如有串聯(lián)線段，試驗(yàn)中可將其打開，分別測(cè)量幾個(gè)并聯(lián)支路的電勢(shì)差，以降低被試?yán)@組的電位； (5) 測(cè)量?jī)x表的一端應(yīng)可靠接地，儀表的量程開始應(yīng)置于zui大位罝，送電指示正常后，再逐級(jí)縮小量程，以避免損壞儀表。做三相變壓器的空載、負(fù)載試驗(yàn)時(shí)，儀器能自動(dòng)判斷接線是否正確。遼寧電子變壓器在線監(jiān)測(cè)系統(tǒng)</p><p
