高精度電容電感測試儀儀器的主要功能及特點

電(dian)力系統(tong)為(wei)了減小無(wu)功損耗，通常采用(yong)并聯(lian)電(dian)容器組(zu)的(de)(de)方(fang)法來提高功率因素。在實際應(ying)用(yong)中，電(dian)容器補償裝置事(shi)故率比較高，這是(shi)由于電(dian)容器裝置工作狀(zhuang)態的(de)(de)特點決定(ding)的(de)(de)。所以(yi)定(ding)期對電(dian)容器裝置檢測，早期發(fa)現(xian)電(dian)容器缺陷，避免(mian)故障(zhang)擴大(da)，是(shi)十分重要的(de)(de)。

現場電(dian)(dian)(dian)容(rong)(rong)器都是成(cheng)組并聯的，用般電(dian)(dian)(dian)容(rong)(rong)表(biao)需將(jiang)引線拆(chai)除后才能(neng)測(ce)量，工(gong)作量大，且容(rong)(rong)易造成(cheng)接線錯誤。科拓電(dian)(dian)(dian)氣(qi)全(quan)自動電(dian)(dian)(dian)容(rong)(rong)電(dian)(dian)(dian)感(gan)測(ce)試儀可以在不拆(chai)線的狀態下，測(ce)量成(cheng)組并聯著的單(dan)個電(dian)(dian)(dian)容(rong)(rong)器，同(tong)時(shi)也能(neng)夠測(ce)量電(dian)(dian)(dian)感(gan)和電(dian)(dian)(dian)流(liu)，接線方(fang)便，操作簡單(dan)，大大提高了現場測(ce)試的效(xiao)率。也可避免(mian)拆(chai)裝引線帶來的出錯可能(neng)性(xing)。

1.　電(dian)容的(de)測(ce)(ce)量：儀(yi)器可不(bu)拆線測(ce)(ce)試(shi)(shi)成組(zu)電(dian)容中(zhong)的(de)單個電(dian)容,測(ce)(ce)試(shi)(shi)方便。顯(xian)示(shi)測(ce)(ce)試(shi)(shi)的(de)電(dian)容結(jie)果的(de)同時顯(xian)示(shi)測(ce)(ce)試(shi)(shi)的(de)電(dian)壓,電(dian)流(liu),功率,頻率。

2.　電感(gan)的(de)測(ce)量(liang)：儀器顯示(shi)測(ce)量(liang)的(de)電感(gan)值并同時顯示(shi)測(ce)量(liang)時施加(jia)的(de)電壓,電流(liu),功率,頻率。

3.　電流(liu)的(de)測量：顯示電流(liu)的(de)同時顯示電流(liu)的(de)頻率。

4.  自動換擋功能：儀器能夠根據被測電容（電感(gan)）的大小(xiao)自動切換輸出(chu)電壓檔位(wei)。

 5.儀器(qi)大屏幕(mu)液(ye)晶(jing)顯(xian)示。 儀器(qi)中文菜(cai)單，中文提示，操作簡單。

6． 儀器(qi)自帶打(da)印(yin)機,可打(da)印(yin)顯(xian)示(shi)數據(ju),內置存(cun)儲器(qi),掉電不丟失,儀器(qi)可存(cun)儲20組數據(ju)。

7． *日歷、時鐘功能,可進行時間校準。

8． 試(shi)驗電源(yuan)設有過電流(liu)保(bao)護，電源(yuan)輸出短路不會損壞儀器。
