style="text-indent:25px">電源變壓器的檢測(cè)：A、通過(guò)觀察變壓器的外貌來(lái)檢查其是否有明顯異常現(xiàn)象。如線圈引線是否斷裂，脫焊，絕緣材料是否有燒焦痕跡，鐵芯緊固螺桿是否有松動(dòng)，硅鋼片有無(wú)銹蝕，繞組線圈是否有外露等。B、絕緣性測(cè)試。用萬(wàn)用表R×10k擋分別測(cè)量鐵芯與初級(jí)，初級(jí)與各次級(jí)、鐵芯與各次級(jí)、靜電屏蔽層與衩次級(jí)、次級(jí)各繞組間的電阻值，萬(wàn)用表指針均應(yīng)指在無(wú)窮大位置不動(dòng)。否則，說(shuō)明變壓器絕緣性能不良。C、線圈通斷的檢測(cè)。將萬(wàn)用表置于R×1擋，測(cè)試中，若某個(gè)繞組的電阻值為無(wú)窮大，則說(shuō)明此繞組有斷路性故障。D，東莞超輕型試驗(yàn)變壓器、判別初，東莞超輕型試驗(yàn)變壓器、次級(jí)線圈。電源變壓器初級(jí)引腳和次級(jí)引腳一般都是分別從兩側(cè)引出的，并且初級(jí)繞組多標(biāo)有220V字樣，次級(jí)繞組則標(biāo)出額定電壓值，東莞超輕型試驗(yàn)變壓器，如15V、24V、35V等。再根據(jù)這些標(biāo)記進(jìn)行識(shí)別。在變壓器的日常維護(hù)時(shí)需要注意觀察外觀，主要檢查變壓器外部是否存在滲油、是否存在零部件冒煙或放電現(xiàn)象。東莞超輕型試驗(yàn)變壓器</p><div

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(kāi)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(kāi)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。湖北局放試驗(yàn)變壓器儀器在運(yùn)輸、儲(chǔ)存及工作中應(yīng)避免強(qiáng)烈震動(dòng)、陽(yáng)光直射和磁場(chǎng)的影響。</p><div
