MD-20A單相電容電感測試儀（20A）

一、產品概述

無功(gong)補(bu)償電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)是(shi)滿(man)足電(dian)(dian)(dian)(dian)力系統(tong)無功(gong)平(ping)衡(heng)的(de)重(zhong)要(yao)設備(bei)(bei)。近(jin)年來無功(gong)問題得(de)到(dao)了電(dian)(dian)(dian)(dian)業(ye)部(bu)門的(de)普遍重(zhong)視，無功(gong)補(bu)償成套裝(zhuang)(zhuang)置已(yi)大(da)量投(tou)入配(pei)電(dian)(dian)(dian)(dian)網(wang)運行。電(dian)(dian)(dian)(dian)能供給要(yao)求系統(tong)有功(gong)與無功(gong)實(shi)時平(ping)衡(heng)。因此，無功(gong)補(bu)償裝(zhuang)(zhuang)置應(ying)滿(man)足自動跟蹤、實(shi)時補(bu)償的(de)要(yao)求，這就(jiu)不可避免(mian)地要(yao)頻繁投(tou)、切無功(gong)補(bu)償電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)組(zu)。電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)組(zu)的(de)投(tou)、切操(cao)作，就(jiu)會產(chan)生(sheng)過電(dian)(dian)(dian)(dian)流與過電(dian)(dian)(dian)(dian)壓沖(chong)擊，引起電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)損壞。為保(bao)證設備(bei)(bei)的(de)可靠性，早(zao)期發現電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)缺陷，避免(mian)故(gu)障擴大(da)，需要(yao)定期進行檢測(ce)(ce)(ce)。而(er)在現場(chang)電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)都是(shi)成組(zu)并聯的(de)，傳(chuan)統(tong)方法是(shi)將電(dian)(dian)(dian)(dian)容(rong)(rong)匯流排拆除，然后用(yong)老式電(dian)(dian)(dian)(dian)容(rong)(rong)表進行測(ce)(ce)(ce)量，由于(yu)電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)組(zu)是(shi)由幾十至(zhi)上百個小電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)組(zu)成，要(yao)拆線(xian)測(ce)(ce)(ce)量電(dian)(dian)(dian)(dian)容(rong)(rong)量的(de)工作量很大(da)，而(er)且經常拆線(xian)會使得(de)螺絲滑牙或沒有上緊(jin)而(er)留(liu)下安全(quan)隱患(huan)，也容(rong)(rong)易造成電(dian)(dian)(dian)(dian)容(rong)(rong)的(de)二(er)次(ci)損壞。因此，非常期望有一(yi)種(zhong)測(ce)(ce)(ce)試(shi)儀器(qi)(qi)(qi)不用(yong)拆線(xian)就(jiu)能測(ce)(ce)(ce)量各個小電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)(qi)的(de)電(dian)(dian)(dian)(dian)容(rong)(rong)量，減輕檢修(xiu)人員(yuan)的(de)負擔，提高檢修(xiu)工作的(de)效率，提高配(pei)電(dian)(dian)(dian)(dian)網(wang)運行的(de)安全(quan)性。

針對(dui)現(xian)場(chang)的(de)(de)(de)(de)實際情況，我公司經過攻關，終研制出一(yi)種利(li)用新(xin)試驗方(fang)法進行(xing)測(ce)(ce)(ce)(ce)量的(de)(de)(de)(de)儀(yi)器，這就是“型電(dian)(dian)容電(dian)(dian)感測(ce)(ce)(ce)(ce)試儀(yi)”。該(gai)儀(yi)器可以在不拆線(xian)的(de)(de)(de)(de)狀(zhuang)態下，測(ce)(ce)(ce)(ce)量成組并聯電(dian)(dian)容器的(de)(de)(de)(de)單個電(dian)(dian)容器，同時也能夠(gou)測(ce)(ce)(ce)(ce)量各種電(dian)(dian)抗器的(de)(de)(de)(de)電(dian)(dian)感，本儀(yi)器還能測(ce)(ce)(ce)(ce)量工(gong)頻狀(zhuang)況下的(de)(de)(de)(de)電(dian)(dian)流，該(gai)儀(yi)器接線(xian)方(fang)便，操(cao)作簡單，減(jian)輕了(le)檢(jian)修人員的(de)(de)(de)(de)工(gong)作負擔，大(da)(da)大(da)(da)提(ti)高了(le)現(xian)場(chang)的(de)(de)(de)(de)測(ce)(ce)(ce)(ce)試效率，為電(dian)(dian)網的(de)(de)(de)(de)正(zheng)常(chang)運行(xing)提(ti)供了(le)安全保障。
