交直流耐壓試驗儀（圖）概述：

本(ben)廠依據《試(shi)驗變壓(ya)器國家標準》、行(xing)業標準《JB/T9641-1999》自行(xing)研(yan)(yan)制生產(chan)的(de)輕型(xing)交流(liu)、交直(zhi)流(liu)兩用(yong)(yong)油浸式(shi)和(he)干式(shi)系(xi)(xi)列變壓(ya)器，具有體積小、重(zhong)量輕、結構(gou)緊湊、功能齊全、通用(yong)(yong)性強(qiang)和(he)使用(yong)(yong)方便(bian)等特點。特別適用(yong)(yong)于電力(li)系(xi)(xi)統、工礦企(qi)業、科研(yan)(yan)部門等對各種電氣設備(bei)、電器元件、絕緣(yuan)材(cai)料進行(xing)工頻(pin)或直(zhi)流(liu)高壓(ya)下的(de)絕緣(yuan)強(qiang)度及泄(xie)漏試(shi)驗，是高壓(ya)試(shi)驗中(zhong)*的(de)重(zhong)要設備(bei)。

交直流耐壓試驗儀（圖）產品結構：

本(ben)系列(lie)輕型高壓試驗變(bian)壓器(qi)(qi)采用單框(kuang)式(shi)鐵(tie)芯結構(gou)。初級繞組(zu)(zu)繞在(zai)鐵(tie)芯上，高壓繞組(zu)(zu)在(zai)外(wai)。這種同軸布置有效地減少了漏(lou)磁(ci)，因而(er)增(zeng)大了繞組(zu)(zu)間的(de)(de)耦(ou)合。圖1所(suo)示的(de)(de)油浸(jin)式(shi)試驗變(bian)壓器(qi)(qi)外(wai)殼制成與器(qi)(qi)芯配合較佳(jia)的(de)(de)八(ba)角形結構(gou)，整(zheng)體(ti)外(wai)觀顯得美觀大方。

工作原理：

本系列交直流耐壓測試儀為(wei)(wei)單相變(bian)壓(ya)(ya)(ya)(ya)器，經操作箱(xiang)（臺）內(nei)調壓(ya)(ya)(ya)(ya)器輸(shu)出(chu)可(ke)調的0~200V或0~400V電壓(ya)(ya)(ya)(ya)至試(shi)驗(yan)變(bian)壓(ya)(ya)(ya)(ya)器的初級繞(rao)組(zu)，根據電磁感應原理，在次級繞(rao)組(zu)可(ke)獲得可(ke)調的高(gao)(gao)電壓(ya)(ya)(ya)(ya)。單臺試(shi)驗(yan)變(bian)壓(ya)(ya)(ya)(ya)器工(gong)作接(jie)線原理見附圖一；高(gao)(gao)壓(ya)(ya)(ya)(ya)套管(guan)中裝有高(gao)(gao)壓(ya)(ya)(ya)(ya)硅(gui)堆(dui)，串接(jie)在高(gao)(gao)壓(ya)(ya)(ya)(ya)回路(lu)中作半波整流。當短路(lu)桿將高(gao)(gao)壓(ya)(ya)(ya)(ya)硅(gui)堆(dui)短接(jie)時(shi)，輸(shu)出(chu)的高(gao)(gao)壓(ya)(ya)(ya)(ya)為(wei)(wei)工(gong)頻交流。擰出(chu)短路(lu)桿時(shi)輸(shu)出(chu)的高(gao)(gao)壓(ya)(ya)(ya)(ya)為(wei)(wei)直(zhi)流。
