直(zhi)流數顯(xian)直(zhi)流驗電(dian)器使用說明書

一、直(zhi)流數顯驗電(dian)器(qi)概(gai)述(shu)：

高(gao)壓直流驗電器是我(wo)公(gong)司采用先進元(yuan)器件，獨立(li)研制的產品(pin)，性(xing)能可(ke)靠。所有(you)參(can)數為我(wo)公(gong)司企業(ye)標(biao)準。

直流驗電器，其指示器與操作(zuo)桿(gan)都應用交流驗電器的結構與工藝，所不同之處在(zai)于直流驗電器操作(zuo)桿(gan)

上(shang)增設了數顯(xian)電壓表(biao)及接地引下(xia)插孔，用于連接接地線，接地端沒有正負極(ji)之分。

二、直(zhi)流數顯驗(yan)電器參數：（直(zhi)流）

額定電壓: ±    1.5  KV,             啟動電壓 : ± 0.001 KV。

限制耐壓 : ±   1.9 KV。，操作桿耐壓: 45    KV/1min。

三、直流驗電器使用環境條件(jian)：

直流驗電器環境溫度：-25℃～+55℃

直流(liu)驗電(dian)器使用場合：戶內和戶外(wai)無陰雨天(tian)氣，相(xiang)對濕度小于85%。

四、直流驗電器使用(yong)方法(fa)及注意事(shi)項：

1. 為保(bao)證人身(shen)和設備(bei)的(de)安全，確保(bao)驗電器(qi)的(de)完好(hao)性，驗電器(qi)應存放在空氣流通、環境干燥的(de)場所。

2.驗(yan)電(dian)(dian)操(cao)(cao)(cao)作前(qian)應(ying)對驗(yan)電(dian)(dian)器(qi)進(jin)行自檢，方法是：打開電(dian)(dian)源(yuan)開關數顯表應(ying)該很快歸零(ling)。若無指示時不得進(jin)行驗(yan)電(dian)(dian)操(cao)(cao)(cao)作。驗(yan)電(dian)(dian)操(cao)(cao)(cao)作前(qian)還(huan)須(xu)檢查(cha)接地引(yin)下線是否(fou)完好，接觸點是否(fou)可靠。

3.驗(yan)電操作(zuo)順序(xu)為：

（1）拉伸所有(you)絕緣(yuan)操(cao)作(zuo)桿(gan)，使其拉足并定位。將數顯表卡(ka)在(zai)絕緣(yuan)桿(gan)第二節底部標志線位置。

（2）將測(ce)試線上端的插(cha)(cha)頭可靠地插(cha)(cha)進首節桿末端的插(cha)(cha)孔內，另一端插(cha)(cha)到數顯(xian)表紅色測(ce)試插(cha)(cha)孔內。

（3）將接地(di)引下線的插頭插到(dao)數顯表(biao)黑(hei)色插孔內，另(ling)一(yi)端(duan)可靠(kao)地(di)夾在良好的接地(di)軌或極(ji)上(shang)。

（4）操(cao)作(zuo)人員(yuan)應先將該驗電(dian)(dian)器在有電(dian)(dian)部位(wei)(wei)上(shang)驗電(dian)(dian)，證明(ming)該驗電(dian)(dian)器性能(neng)完(wan)好，然(ran)后在施工部位(wei)(wei)上(shang)驗電(dian)(dian)，確認施工部位(wei)(wei)是(shi)否帶電(dian)(dian)。

注意：驗電器應注意(yi)在干燥(zao)場合保存(cun)，顯(xian)示不正常時應首先(xian)考慮更換電池。數(shu)顯(xian)表內(nei)電池半年應該更換，以(yi)防電池漏夜損壞(huai)元件。
