金泉電力告訴您：電力變壓器的作用是什么呢？

電(dian)力變(bian)壓器是由繞在(zai)同一鐵芯(xin)上(shang)的兩個或兩個以上(shang)的線(xian)圈繞組組成，它是國(guo)內(nei)變(bian)壓器的高(gao)壓繞組一般聯成Y接法。

它(ta)是(shi)(shi)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)廠(chang)和(he)變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)所的主要(yao)設(she)備之(zhi)(zhi)一。變(bian)壓(ya)(ya)(ya)(ya)器的作用(yong)是(shi)(shi)多方面的不僅能(neng)升(sheng)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)把(ba)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)送到用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)地(di)區(qu)，還能(neng)把(ba)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)降(jiang)低為(wei)各級使(shi)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，以滿足(zu)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)的需要(yao)。總之(zhi)(zhi)，升(sheng)壓(ya)(ya)(ya)(ya)與(yu)(yu)降(jiang)壓(ya)(ya)(ya)(ya)都必(bi)須由變(bian)壓(ya)(ya)(ya)(ya)器來完成。在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)力系統傳送電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)的過程中，必(bi)然會產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)和(he)功(gong)率兩部分損(sun)耗(hao)(hao)，在(zai)輸(shu)送同(tong)一功(gong)率時電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)損(sun)耗(hao)(hao)與(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)成反比，功(gong)率損(sun)耗(hao)(hao)與(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)的平方成反比。利(li)用(yong)變(bian)壓(ya)(ya)(ya)(ya)器提高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，減少了送電(dian)(dian)(dian)(dian)(dian)(dian)損(sun)失。

電(dian)力(li)變壓(ya)(ya)器(qi)市場需(xu)求旺盛(sheng)。電(dian)力(li)變壓(ya)(ya)器(qi)是(shi)勞動密集型(xing)產品(pin)(pin)，并以用戶定制生產為(wei)主，近幾年來國內外(wai)市場需(xu)求旺盛(sheng)，成為(wei)發(fa)展迅速的熱(re)門(men)產品(pin)(pin)。數(shu)據(ju)顯示而印度將增(zeng)長(chang)25%。通信、計算機(ji)、消費類電(dian)子(zi)產品(pin)(pin)是(shi)其三(san)大(da)主力(li)市場，其中(zhong)通信需(xu)求的增(zeng)長(chang)將起(qi)很大(da)的推動作用，現全球(qiu)電(dian)源變壓(ya)(ya)器(qi)年需(xu)求已超過百億(yi)美元(yuan)，并向表面安(an)裝、高(gao)功率(lv)和高(gao)壓(ya)(ya)方面發(fa)展。

電(dian)力變壓器(qi)的特(te)點：

1、在(zai)大機(ji)組與系統并列時,降(jiang)低高(gao)壓(ya)(ya)母(mu)線上工頻(pin)穩(wen)態電壓(ya)(ya),便于發電機(ji)同期并列。

2、改善長輸電(dian)線路(lu)上的電(dian)壓(ya)分(fen)布。

3、使輕(qing)負荷時(shi)線(xian)路中的無(wu)功功率(lv)盡可能(neng)就地平衡,防止無(wu)功功率(lv)不合理流動,同時(shi)也減輕(qing)了線(xian)路上(shang)的功率(lv)損失(shi)。
