MS-500L 全自動電容電感測試儀 1、不拆線快速測量并聯電容器組中的單個電容器的電容值、放電電阻值
       2、不損壞電容器套管，不僅工作量大而且易損壞電容器。
       3、不拆線快速測量電抗器的電感、電抗值現場
       4、電容(rong)表輸出(chu)電壓(ya)低而導致故(gu)障檢出(chu)率低。

       無功補償電容器是滿足電力系統無功平衡的重要設備。近年來無功問題得到了電業部門的普遍重視，無功補償成套裝置已大量投入配電網運行。電能供給要求系統有功與無功實時平衡。因此，無功補償裝置應滿足自動跟蹤、實時補償的要求，這就不可避免地要頻繁投、切無功補償電容器組。電容器組的投、切操作，就會產生過電流與過電壓沖擊，引起電容器損壞。
       為保(bao)證電(dian)(dian)容(rong)(rong)(rong)(rong)電(dian)(dian)感(gan)測(ce)試儀的(de)(de)可(ke)靠(kao)性(xing)，早(zao)期發(fa)現(xian)電(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)缺陷，避(bi)免故障擴大(da)，需要(yao)定期進行(xing)檢測(ce)。而(er)(er)在現(xian)場電(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)都是(shi)成組并聯的(de)(de)，傳統方法是(shi)將電(dian)(dian)容(rong)(rong)(rong)(rong)匯(hui)流排拆(chai)(chai)除，然后用(yong)老式電(dian)(dian)容(rong)(rong)(rong)(rong)表進行(xing)測(ce)量(liang)，由于電(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)組是(shi)由幾(ji)十至(zhi)上(shang)百個小電(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)組成，要(yao)拆(chai)(chai)線(xian)測(ce)量(liang)電(dian)(dian)容(rong)(rong)(rong)(rong)量(liang)的(de)(de)工作量(liang)很大(da)，而(er)(er)且經常拆(chai)(chai)線(xian)會(hui)使得螺絲滑牙或沒(mei)有上(shang)緊而(er)(er)留(liu)下安全隱患，也容(rong)(rong)(rong)(rong)易(yi)造成電(dian)(dian)容(rong)(rong)(rong)(rong)的(de)(de)二次損壞(huai)。因此，非常期望有一種測(ce)試儀器(qi)不(bu)用(yong)拆(chai)(chai)線(xian)就能測(ce)量(liang)各個小電(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)的(de)(de)電(dian)(dian)容(rong)(rong)(rong)(rong)量(liang)，減輕檢修人員的(de)(de)負擔，提高(gao)檢修工作的(de)(de)效率，提高(gao)配(pei)電(dian)(dian)網運行(xing)的(de)(de)安全性(xing)。
