電力變壓器的作用

電(dian)(dian)(dian)(dian)(dian)(dian)力變(bian)(bian)(bian)壓(ya)器(qi)(qi)是(shi)發電(dian)(dian)(dian)(dian)(dian)(dian)廠和(he)變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)所的主(zhu)要設備(bei)之一。變(bian)(bian)(bian)壓(ya)器(qi)(qi)的作用(yong)是(shi)多方面的不僅能升高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)把電(dian)(dian)(dian)(dian)(dian)(dian)能送(song)到用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)地區，還能把電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)降低為各級使用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，以滿足用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)的需要。總之，升壓(ya)與(yu)(yu)降壓(ya)都必(bi)須由變(bian)(bian)(bian)壓(ya)器(qi)(qi)來完成(cheng)。在電(dian)(dian)(dian)(dian)(dian)(dian)力系統(tong)傳送(song)電(dian)(dian)(dian)(dian)(dian)(dian)能的過程(cheng)中(zhong)，必(bi)然會(hui)產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)功(gong)率兩部分損耗，在輸送(song)同一功(gong)率時電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)損耗與(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)成(cheng)反(fan)比，功(gong)率損耗與(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的平方成(cheng)反(fan)比。利(li)用(yong)變(bian)(bian)(bian)壓(ya)器(qi)(qi)提(ti)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，減少(shao)了送(song)電(dian)(dian)(dian)(dian)(dian)(dian)損失。

變(bian)(bian)壓(ya)器(qi)(qi)是由(you)繞(rao)(rao)在同(tong)一(yi)鐵芯(xin)上的(de)兩(liang)個或(huo)(huo)兩(liang)個以(yi)上的(de)線圈繞(rao)(rao)組組成，繞(rao)(rao)組之間(jian)是通過(guo)交(jiao)變(bian)(bian)磁場而聯系(xi)著并按電磁感應原理(li)工作。變(bian)(bian)壓(ya)器(qi)(qi)安裝位置應考慮便于運(yun)行(xing)、檢修和運(yun)輸，同(tong)時應選擇(ze)安全可(ke)靠(kao)的(de)地(di)方。在使用變(bian)(bian)壓(ya)器(qi)(qi)時必(bi)須合理(li)地(di)選用變(bian)(bian)壓(ya)器(qi)(qi)的(de)額(e)定容(rong)量(liang)。變(bian)(bian)壓(ya)器(qi)(qi)空載(zai)(zai)運(yun)行(xing)時，需用較大的(de)無(wu)功功率(lv)。這(zhe)些無(wu)功功率(lv)要(yao)由(you)供電系(xi)統供給(gei)。變(bian)(bian)壓(ya)器(qi)(qi)的(de)容(rong)量(liang)若選擇(ze)過(guo)大，不(bu)但增(zeng)加(jia)了初投(tou)資，而且使變(bian)(bian)壓(ya)器(qi)(qi)長期(qi)處于空載(zai)(zai)或(huo)(huo)輕載(zai)(zai)運(yun)行(xing)，使空載(zai)(zai)損耗(hao)的(de)比重增(zeng)大，功率(lv)因數降低，網絡損耗(hao)增(zeng)加(jia)，這(zhe)樣運(yun)行(xing)既不(bu)經濟又不(bu)合理(li)。變(bian)(bian)壓(ya)器(qi)(qi)容(rong)量(liang)選擇(ze)過(guo)小，會使變(bian)(bian)壓(ya)器(qi)(qi)長期(qi)過(guo)負(fu)荷，易損壞設備。因此，變(bian)(bian)壓(ya)器(qi)(qi)的(de)額(e)定容(rong)量(liang)應根據用電負(fu)荷的(de)需要(yao)進(jin)行(xing)選擇(ze)，不(bu)宜過(guo)大或(huo)(huo)過(guo)小。
