一、兆歐表如何使用

1、用(yong)絕(jue)緣良好的(de)單根銅芯(xin)軟導線(xian)做兆(zhao)歐表(biao)與被測試點之間的(de)測量連接(jie)線(xian)，不能用(yong)絞合線(xian)。兩根測量連接(jie)線(xian)不可絞合，也不要(yao)接(jie)觸(chu)被測設備或線(xian)路的(de)表(biao)面。

2、測量前，切(qie)斷被測設(she)備或線路(lu)的電(dian)源，并(bing)將導電(dian)部分(fen)接地放電(dian)，防止電(dian)容儲能(neng)放電(dian)傷人和燒壞儀表(biao)。然后擦干凈被測試點，以(yi)免影響測量的準確性。

3、測量(liang)時，轉(zhuan)(zhuan)(zhuan)動搖柄的速度應由慢(man)(man)逐漸到(dao)快，然后使之保持(chi)在(zai)額定(ding)轉(zhuan)(zhuan)(zhuan)速(一般為120轉(zhuan)(zhuan)(zhuan)／分(fen))，允許轉(zhuan)(zhuan)(zhuan)速在(zai)±20％范(fan)圍(wei)內(nei)變動，但最高不(bu)得(de)(de)超(chao)過150轉(zhuan)(zhuan)(zhuan)／分(fen)。搖動不(bu)得(de)(de)忽(hu)快忽(hu)慢(man)(man)，否則指針會搖擺不(bu)定(ding)。讀(du)數(shu)應在(zai)均勻搖動一分(fen)鐘后待(dai)指針穩(wen)定(ding)下來讀(du)取。若(ruo)發現指針為零(ling)，表明被測絕緣物存在(zai)短路故障，應立刻停止轉(zhuan)(zhuan)(zhuan)動搖柄，以防表內(nei)線圈因發熱而損壞。

4、測(ce)(ce)量(liang)完畢后，要(yao)先對被測(ce)(ce)設備或線(xian)路(lu)進行(xing)充分放電(dian)，再進行(xing)拆線(xian)收尾工作。若兆歐(ou)表(biao)尚在轉動或雖(sui)已停(ting)止轉動但被測(ce)(ce)設備或線(xian)路(lu)還未放電(dian)時(shi)(shi)，不(bu)能用手觸及被測(ce)(ce)部分或進行(xing)拆線(xian)，以防觸電(dian)。在測(ce)(ce)量(liang)電(dian)容性設備或線(xian)路(lu)的絕緣電(dian)阻時(shi)(shi)。應(ying)在取得穩定讀數后先小(xiao)心取下測(ce)(ce)量(liang)連(lian)接線(xian)，再停(ting)止轉動搖柄，以免被測(ce)(ce)設備或線(xian)路(lu)向兆歐(ou)表(biao)倒充電(dian)而(er)損壞儀(yi)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(ran)后調檔，先用最大(da)檔開(kai)始，調零把兩個(ge)表(biao)夾接觸在一起(qi)，然(ran)后開(kai)始搖，并且(qie)調節(jie)指針到零。

2、然后(hou)分開表夾，一(yi)個夾接地樁，一(yi)個夾測量(liang)體，然后(hou)搖用最快的(de)速(su)度去搖就搖，是要超過120轉。

3、觀察測(ce)出(chu)的結果是否在(zai)測(ce)量(liang)范圍的2/3內來測(ce)試。

三、兆歐表的作用

兆(zhao)歐(ou)表俗稱搖(yao)表，是電(dian)工常(chang)用(yong)(yong)的一種測量儀表。兆(zhao)歐(ou)表主要(yao)用(yong)(yong)來檢查(cha)電(dian)氣設(she)(she)備(bei)、家用(yong)(yong)電(dian)器或電(dian)氣線(xian)(xian)路對地及相間的絕緣(yuan)電(dian)阻，以保證這些設(she)(she)備(bei)、電(dian)器和線(xian)(xian)路工作在(zai)正常(chang)狀態(tai)，避免發(fa)生觸電(dian)傷亡(wang)及設(she)(she)備(bei)損(sun)壞等事故。
