變壓器原理

變(bian)(bian)壓(ya)(ya)(ya)器(qi)是變(bian)(bian)換交流(liu)(liu)電壓(ya)(ya)(ya)、電流(liu)(liu)和阻(zu)抗的(de)(de)(de)器(qi)件(jian)，當(dang)初(chu)級(ji)線(xian)圈(quan)(quan)中通(tong)有交流(liu)(liu)電流(liu)(liu)時，鐵芯（或磁(ci)芯）中便產生(sheng)交流(liu)(liu)磁(ci)通(tong)，使次級(ji)線(xian)圈(quan)(quan)中感(gan)(gan)應出(chu)電壓(ya)(ya)(ya)（或電流(liu)(liu)）。變(bian)(bian)壓(ya)(ya)(ya)器(qi)由(you)鐵芯（或磁(ci)芯）和線(xian)圈(quan)(quan)組成，線(xian)圈(quan)(quan)有兩個(ge)或兩個(ge)以上的(de)(de)(de)繞組，其(qi)中接電源的(de)(de)(de)繞組叫初(chu)級(ji)線(xian)圈(quan)(quan)，正(zheng)泰(tai)變(bian)(bian)壓(ya)(ya)(ya)器(qi)價格(ge)，其(qi)余的(de)(de)(de)繞組叫次級(ji)線(xian)圈(quan)(quan)。在發電機中，不管是線(xian)圈(quan)(quan)運(yun)動通(tong)過磁(ci)場或磁(ci)場運(yun)動通(tong)過固(gu)定(ding)線(xian)圈(quan)(quan)，均(jun)能在線(xian)圈(quan)(quan)中感(gan)(gan)應電勢，此兩種情況，磁(ci)通(tong)的(de)(de)(de)值均(jun)不變(bian)(bian)，但與線(xian)圈(quan)(quan)相(xiang)交鏈的(de)(de)(de)磁(ci)通(tong)數量(liang)卻有變(bian)(bian)動，正(zheng)泰(tai)變(bian)(bian)壓(ya)(ya)(ya)器(qi)供(gong)應商，這(zhe)是互感(gan)(gan)應的(de)(de)(de)原理(li)。變(bian)(bian)壓(ya)(ya)(ya)器(qi)就是一種利(li)用電磁(ci)互感(gan)(gan)應，變(bian)(bian)換電壓(ya)(ya)(ya)，電流(liu)(liu)和阻(zu)抗的(de)(de)(de)器(qi)件(jian)。

怎(zen)樣干燥控(kong)制變壓器？

感應(ying)加熱法：這種方法是將器(qi)身(shen)放在油箱內，外(wai)繞組線(xian)(xian)圈通(tong)以(yi)工頻電(dian)流，利(li)用油箱壁(bi)(bi)中渦流損耗的(de)(de)發熱來干燥(zao)。此時箱壁(bi)(bi)的(de)(de)溫(wen)度不應(ying)超過115~120℃，器(qi)身(shen)溫(wen)度不應(ying)超過90~95℃。為了纏繞線(xian)(xian)圈的(de)(de)方便，盡可能使線(xian)(xian)圈的(de)(de)匝(za)數少些或電(dian)流小(xiao)些，一般電(dian)流選150A，正(zheng)泰變壓器(qi)哪家好，導(dao)線(xian)(xian)可有用35~50mm2的(de)(de)導(dao)線(xian)(xian)。油箱壁(bi)(bi)上(shang)可墊(dian)石棉條多根(gen)，導(dao)線(xian)(xian)繞在石棉條上(shang)。

變壓器的鐵芯需要接地(di)的原因

變壓器(qi)(qi)是利(li)用電(dian)磁(ci)感(gan)應的(de)(de)原理來改變交流電(dian)壓的(de)(de)裝置，運行上變壓器(qi)(qi)的(de)(de)鐵芯及其他附件都處于繞組周圍的(de)(de)電(dian)場內，如不接地(di)，正(zheng)泰變壓器(qi)(qi)，鐵芯及其他附件必(bi)然感(gan)應一(yi)定的(de)(de)電(dian)壓。

在外加電(dian)(dian)(dian)壓(ya)的作(zuo)用下，當感應電(dian)(dian)(dian)壓(ya)超過對地(di)放電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)時，就會(hui)產生(sheng)放電(dian)(dian)(dian)現象。為了避免變(bian)壓(ya)器的內部放電(dian)(dian)(dian)，所以要將鐵芯接地(di)。如(ru)果長期(qi)過載運行，會(hui)引(yin)起線圈(quan)發熱(re)，使(shi)絕(jue)緣逐漸老化，匣(xia)間(jian)短路、相間(jian)短路或(huo)對地(di)短路及油的分解。

變壓器鐵芯絕(jue)緣老化或(huo)夾緊(jin)螺栓套(tao)管損壞，會使鐵芯產(chan)生很大的渦(wo)流，鐵芯長期發熱造成絕(jue)緣老化，變壓器檢修吊芯時，應注意保護線圈或(huo)絕(jue)緣套(tao)管，如果發現有(you)擦破損傷，及時處理(li)。
