WG-15交流低零值絕緣子帶電檢測儀

一．概述
根據DC/T626-2005國電(dian)(dian)(dian)(dian)標準，開發研究的(de)(de)絕緣(yuan)(yuan)子分(fen)布電(dian)(dian)(dian)(dian)壓(ya)(ya)測(ce)(ce)(ce)量(liang)表主要用(yong)于交(jiao)流(liu)線(xian)路35～500KV的(de)(de)帶電(dian)(dian)(dian)(dian)測(ce)(ce)(ce)量(liang)過(guo)線(xian)塔的(de)(de)絕緣(yuan)(yuan)子串電(dian)(dian)(dian)(dian)壓(ya)(ya)分(fen)布值(zhi)。也可用(yong)于試驗室內各種(zhong)35KV以(yi)及交(jiao)流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)測(ce)(ce)(ce)量(liang)。是一種(zhong)理想的(de)(de)保障(zhang)線(xian)路運行(xing)安(an)全的(de)(de)檢測(ce)(ce)(ce)儀表和(he)帶電(dian)(dian)(dian)(dian)作業(ye)輔助工具。絕緣(yuan)(yuan)子分(fen)布電(dian)(dian)(dian)(dian)壓(ya)(ya)測(ce)(ce)(ce)量(liang)表，用(yong)于35～500KV的(de)(de)過(guo)線(xian)塔的(de)(de)絕緣(yuan)(yuan)子串電(dian)(dian)(dian)(dian)壓(ya)(ya)分(fen)布值(zhi)的(de)(de)檢測(ce)(ce)(ce)。檢測(ce)(ce)(ce)時，作業(ye)人員可用(yong)操作桿進行(xing)作業(ye)，采用(yong)電(dian)(dian)(dian)(dian)壓(ya)(ya)信號感應原(yuan)理和(he)液晶顯示電(dian)(dian)(dian)(dian)壓(ya)(ya)值(zhi)，不存(cun)在放(fang)電(dian)(dian)(dian)(dian)過(guo)程，可以(yi)保障(zhang)線(xian)路的(de)(de)運行(xing)安(an)全和(he)作業(ye)人員的(de)(de)安(an)全。

儀工作原理
絕緣子分布電(dian)壓測量(liang)(liang)表采用靜電(dian)感(gan)應式結(jie)構，將被(bei)測電(dian)壓變換成電(dian)場信號進(jin)行(xing)測量(liang)(liang)。因(yin)而阻抗(kang)高，對于(yu)被(bei)測量(liang)(liang)系(xi)統的影響zui小。被(bei)測出的信號經儀器內部電(dian)路放大處理(li)，zui后(hou)以電(dian)壓值的形式，由LCD數字顯示輸出。因(yin)此(ci)測量(liang)(liang)操作迅速，簡單明了。

根據DL/T628-2005電(dian)(dian)(dian)力行(xing)業標準，輸電(dian)(dian)(dian)線路絕緣子分(fen)布(bu)電(dian)(dian)(dian)壓規范性(xing)標準見附表(biao)。各種電(dian)(dian)(dian)壓等(deng)級的(de)絕緣子分(fen)布(bu)電(dian)(dian)(dian)壓不小(xiao)于正常分(fen)布(bu)電(dian)(dian)(dian)壓，見表(biao)一(yi)。

表(biao)(biao)一 各種電(dian)壓(ya)等級(ji)的絕緣子分(fen)布電(dian)壓(ya)不小于正(zheng)常分(fen)布電(dian)壓(ya)表(biao)(biao)

35KV 
 一般正常分布電壓不小于3.5KV 
 
110KV 
 一般正常分布電壓不小于4KV 
 
220KV 
 一般正常分布電壓不小于5KV

 一般正常分布電壓不小于6KV 
 

如果(guo)絕(jue)緣(yuan)子損(sun)壞，則(ze)其上的電壓(ya)必(bi)定低于正常(chang)的電壓(ya)，故(gu)認為(wei)能(neng)承受工作電壓(ya)的絕(jue)緣(yuan)子為(wei)好絕(jue)緣(yuan)子。

絕(jue)緣(yuan)子分(fen)布電(dian)(dian)(dian)(dian)(dian)壓測量(liang)表(biao)在使(shi)用時(shi)，若顯(xian)示電(dian)(dian)(dian)(dian)(dian)壓值(zhi)大于(yu)正常(chang)分(fen)布電(dian)(dian)(dian)(dian)(dian)壓，則認為此絕(jue)緣(yuan)子正常(chang)。若顯(xian)示電(dian)(dian)(dian)(dian)(dian)壓值(zhi)小于(yu)正常(chang)分(fen)布電(dian)(dian)(dian)(dian)(dian)壓，則認為此絕(jue)緣(yuan)子為劣質(zhi)絕(jue)緣(yuan)子。各種電(dian)(dian)(dian)(dian)(dian)壓等級的絕(jue)緣(yuan)子串分(fen)布電(dian)(dian)(dian)(dian)(dian)壓值(zhi)見附表(biao)。絕(jue)緣(yuan)子分(fen)布電(dian)(dian)(dian)(dian)(dian)壓測量(liang)表(biao)的內(nei)部(bu)電(dian)(dian)(dian)(dian)(dian)路采(cai)用低功耗設計，使(shi)用時(shi)極省電(dian)(dian)(dian)(dian)(dian)。全部(bu)電(dian)(dian)(dian)(dian)(dian)路均安裝于(yu)屏(ping)蔽(bi)盒內(nei)。
