PVT系列智能型電機(ji)工頻耐電壓試驗儀 

主(zhu)要特點(dian)

本產品采用電(dian)(dian)(dian)(dian)(dian)動調(diao)壓(ya)器調(diao)節(jie)高壓(ya)試(shi)驗(yan)(yan)變壓(ya)器的(de)初(chu)級輸(shu)入電(dian)(dian)(dian)(dian)(dian)壓(ya)以調(diao)節(jie)整(zheng)機(ji)(ji)高壓(ya)輸(shu)出，升(sheng)壓(ya)啟動后，電(dian)(dian)(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)(dian)(dian)流、試(shi)驗(yan)(yan)時間控制采用自動無極量程設(she)定控制技術，按(an)一定速率(lv)升(sheng)至額定試(shi)驗(yan)(yan)值(zhi)，試(shi)驗(yan)(yan)數(shu)值(zhi)LED顯(xian)示（試(shi)驗(yan)(yan)時間、試(shi)驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)壓(ya)、試(shi)驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)流）；試(shi)驗(yan)(yan)結(jie)束，電(dian)(dian)(dian)(dian)(dian)動調(diao)壓(ya)器仍按(an)相同速率(lv)降(jiang)(jiang)壓(ya)至零；試(shi)驗(yan)(yan)中，產品的(de)漏電(dian)(dian)(dian)(dian)(dian)流超(chao)出額定值(zhi)，儀器自動切(qie)斷高壓(ya)，電(dian)(dian)(dian)(dian)(dian)動調(diao)壓(ya)器自動降(jiang)(jiang)壓(ya)至零，同時電(dian)(dian)(dian)(dian)(dian)鈴(ling)報(bao)警(jing)，報(bao)警(jing)指示燈亮。本機(ji)(ji)設(she)有放電(dian)(dian)(dian)(dian)(dian)按(an)鈕，可釋放被試(shi)產品殘存電(dian)(dian)(dian)(dian)(dian)壓(ya)，保(bao)護操(cao)作人員人身安全；另外，該儀器還(huan)備有警(jing)燈作高壓(ya)警(jing)示和蘑菇型“緊停(ting)”按(an)鈕。

因此(ci)，PVT型電(dian)機(ji)(ji)工頻耐電(dian)壓(ya)試驗儀具(ju)有功能齊(qi)全、操作方(fang)便、靈活、運(yun)行(xing)安全可(ke)靠的特點，廣泛(fan)適用于電(dian)機(ji)(ji)（變壓(ya)器）行(xing)業的制造(zao)及修理單位，是提高(gao)產品可(ke)靠性(xing)的*檢(jian)測儀器。
