一、兆歐表如何使用

1、用絕緣良(liang)好的單根銅芯軟導線做兆歐表與(yu)被測(ce)試點之間的測(ce)量(liang)連(lian)接線，不能用絞合線。兩(liang)根測(ce)量(liang)連(lian)接線不可絞合，也不要接觸被測(ce)設備或線路的表面。

2、測量前，切斷被測設(she)備或線路的電(dian)源(yuan)，并(bing)將導電(dian)部分接地放(fang)電(dian)，防止電(dian)容儲能放(fang)電(dian)傷(shang)人和燒(shao)壞儀表。然后擦(ca)干凈(jing)被測試點，以免影響測量的準確性。

3、測量時，轉(zhuan)(zhuan)(zhuan)動(dong)(dong)(dong)(dong)搖柄的速度應由慢逐漸(jian)到快(kuai)，然后使(shi)之保持在額定轉(zhuan)(zhuan)(zhuan)速(一(yi)般為(wei)120轉(zhuan)(zhuan)(zhuan)／分)，允許(xu)轉(zhuan)(zhuan)(zhuan)速在±20％范(fan)圍內(nei)變動(dong)(dong)(dong)(dong)，但最高不得超過150轉(zhuan)(zhuan)(zhuan)／分。搖動(dong)(dong)(dong)(dong)不得忽快(kuai)忽慢，否則(ze)指針(zhen)會搖擺(bai)不定。讀數應在均勻搖動(dong)(dong)(dong)(dong)一(yi)分鐘(zhong)后待指針(zhen)穩定下(xia)來讀取。若(ruo)發現指針(zhen)為(wei)零，表(biao)明被測絕(jue)緣物存在短路(lu)故(gu)障，應立刻停止轉(zhuan)(zhuan)(zhuan)動(dong)(dong)(dong)(dong)搖柄，以防表(biao)內(nei)線(xian)圈因發熱而(er)損壞。

4、測量(liang)完畢后(hou)，要先對被測設(she)備或線(xian)(xian)(xian)路進(jin)(jin)行充分放(fang)電(dian)(dian)，再進(jin)(jin)行拆(chai)線(xian)(xian)(xian)收尾工作。若兆(zhao)歐表(biao)尚在轉動(dong)或雖已停(ting)止轉動(dong)但被測設(she)備或線(xian)(xian)(xian)路還未放(fang)電(dian)(dian)時(shi)，不能用手(shou)觸(chu)及被測部分或進(jin)(jin)行拆(chai)線(xian)(xian)(xian)，以防觸(chu)電(dian)(dian)。在測量(liang)電(dian)(dian)容性設(she)備或線(xian)(xian)(xian)路的絕緣(yuan)電(dian)(dian)阻時(shi)。應(ying)在取得穩定讀(du)數后(hou)先小心取下測量(liang)連接線(xian)(xian)(xian)，再停(ting)止轉動(dong)搖柄，以免(mian)被測設(she)備或線(xian)(xian)(xian)路向兆(zhao)歐表(biao)倒(dao)充電(dian)(dian)而(er)損(sun)壞(huai)儀表(biao)。

二、兆歐表測量接地電阻怎樣測試

1、先檢查(cha)接線是否正確，然后調檔，先用(yong)最大檔開(kai)始，調零(ling)把兩(liang)個表夾接觸在(zai)一起，然后開(kai)始搖，并且調節指針到零(ling)。

2、然(ran)后(hou)分開表夾，一個夾接地樁，一個夾測量體，然(ran)后(hou)搖用最快的速度去(qu)搖就搖，是要超過120轉。

3、觀察測出(chu)的結果是否在(zai)測量(liang)范圍(wei)的2/3內來測試(shi)。

三、兆歐表的作用

兆(zhao)歐表(biao)俗稱搖表(biao)，是電(dian)(dian)工常用的(de)(de)一(yi)種測量儀表(biao)。兆(zhao)歐表(biao)主要(yao)用來檢查電(dian)(dian)氣設(she)備、家(jia)用電(dian)(dian)器(qi)或電(dian)(dian)氣線(xian)路對地(di)及(ji)相間的(de)(de)絕緣(yuan)電(dian)(dian)阻，以(yi)保證(zheng)這些設(she)備、電(dian)(dian)器(qi)和(he)線(xian)路工作(zuo)在正常狀態，避(bi)免(mian)發(fa)生觸電(dian)(dian)傷(shang)亡及(ji)設(she)備損壞等事故。
