WG-15絕緣子電壓分布測試儀

一．概述
根(gen)據DC/T626-2005國電(dian)(dian)(dian)(dian)(dian)標準(zhun)，開發研(yan)究(jiu)的(de)(de)絕緣(yuan)(yuan)子(zi)(zi)分(fen)布(bu)電(dian)(dian)(dian)(dian)(dian)壓測量(liang)表(biao)主(zhu)要用(yong)于(yu)交(jiao)流(liu)(liu)線路(lu)35～500KV的(de)(de)帶電(dian)(dian)(dian)(dian)(dian)測量(liang)過(guo)線塔(ta)的(de)(de)絕緣(yuan)(yuan)子(zi)(zi)串(chuan)電(dian)(dian)(dian)(dian)(dian)壓分(fen)布(bu)值。也可用(yong)于(yu)試驗室內各種(zhong)35KV以及交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)壓的(de)(de)測量(liang)。是一(yi)種(zhong)理(li)想的(de)(de)保障(zhang)線路(lu)運行(xing)安全的(de)(de)檢(jian)測儀表(biao)和(he)帶電(dian)(dian)(dian)(dian)(dian)作業(ye)輔助工具。絕緣(yuan)(yuan)子(zi)(zi)分(fen)布(bu)電(dian)(dian)(dian)(dian)(dian)壓測量(liang)表(biao)，用(yong)于(yu)35～500KV的(de)(de)過(guo)線塔(ta)的(de)(de)絕緣(yuan)(yuan)子(zi)(zi)串(chuan)電(dian)(dian)(dian)(dian)(dian)壓分(fen)布(bu)值的(de)(de)檢(jian)測。檢(jian)測時(shi)，作業(ye)人員(yuan)可用(yong)操作桿進行(xing)作業(ye)，采(cai)用(yong)電(dian)(dian)(dian)(dian)(dian)壓信號感應原理(li)和(he)液晶顯示電(dian)(dian)(dian)(dian)(dian)壓值，不存在放電(dian)(dian)(dian)(dian)(dian)過(guo)程，可以保障(zhang)線路(lu)的(de)(de)運行(xing)安全和(he)作業(ye)人員(yuan)的(de)(de)安全。

工作原理
絕緣子分(fen)布電(dian)(dian)壓(ya)測量(liang)表采(cai)用靜電(dian)(dian)感應式(shi)結構，將被測電(dian)(dian)壓(ya)變換成(cheng)電(dian)(dian)場信(xin)號進行測量(liang)。因(yin)而(er)阻抗(kang)高，對于被測量(liang)系統(tong)的(de)影(ying)響zui小。被測出的(de)信(xin)號經儀器內部電(dian)(dian)路放大(da)處理，zui后以電(dian)(dian)壓(ya)值的(de)形(xing)式(shi)，由(you)LCD數字顯示輸出。因(yin)此測量(liang)操作迅速，簡單(dan)明了。

根(gen)據DL/T628-2005電(dian)力行業標(biao)準(zhun)，輸電(dian)線(xian)路絕緣子分布電(dian)壓(ya)規范(fan)性(xing)標(biao)準(zhun)見附表。各種電(dian)壓(ya)等級的絕緣子分布電(dian)壓(ya)不小于正(zheng)常(chang)分布電(dian)壓(ya)，見表一。

如(ru)果絕緣(yuan)子(zi)損壞(huai)，則其上(shang)的電(dian)壓必定(ding)低(di)于(yu)正常(chang)的電(dian)壓，故認為能(neng)承受工(gong)作電(dian)壓的絕緣(yuan)子(zi)為好絕緣(yuan)子(zi)。
