400KV無(wu)局(ju)部(bu)實驗(yan)裝置主要用(yong)于檢驗(yan)各種絕緣(yuan)材料(liao)，絕緣(yuan)結構和電工(gong)產品等耐(nai)受工(gong)頻電壓(ya)的絕緣(yuan)程度，也做(zuo)為變壓(ya)器、互感器、避(bi)雷器等試品的無(wu)局(ju)部(bu)放(fang)電工(gong)頻試驗(yan)電源。

GH-TQSW型串級無局(ju)(ju)部放電(dian)試驗(yan)變(bian)壓器減(jian)小了線(xian)圈(quan)對外的(de)絕緣(yuan)距離，從(cong)而(er)減(jian)小了局(ju)(ju)部放電(dian)量(liang)，Z終保(bao)證設備局(ju)(ju)部放電(dian)量(liang)≤5pC。本發明滿足特(te)高(gao)壓輸(shu)變(bian)電(dian)設備（主(zhu)要(yao)特(te)高(gao)壓GIS）的(de)工(gong)(gong)頻(pin)耐受試驗(yan)及工(gong)(gong)頻(pin)電(dian)壓下的(de)局(ju)(ju)放測(ce)量(liang)；同時滿足開(kai)關聯合(he)試驗(yan)（工(gong)(gong)頻(pin)+工(gong)(gong)頻(pin)，沖擊+工(gong)(gong)頻(pin)）的(de)控制、測(ce)量(liang)接口和絕緣(yuan)水(shui)平要(yao)求。

YWDT-150/350工(gong)(gong)頻無局(ju)(ju)放試驗(yan)變(bian)壓器(qi)主要用于檢(jian)驗(yan)各種絕(jue)緣(yuan)(yuan)材(cai)料，絕(jue)緣(yuan)(yuan)結構和電(dian)工(gong)(gong)產品等耐受工(gong)(gong)頻電(dian)壓的絕(jue)緣(yuan)(yuan)程度，也做為變(bian)壓器(qi)、互感器(qi)、避雷器(qi)等試品的無局(ju)(ju)部(bu)放電(dian)工(gong)(gong)頻試驗(yan)電(dian)源。普(pu)遍應用于電(dian)工(gong)(gong)造造部(bu)門、電(dian)力運行部(bu)門、科研單位和高等院校。

YWDT-300/300工(gong)頻無局放試驗變壓器(qi)主要技術性能 1、試驗變壓器(qi)在額定電(dian)壓UN下(xia)可連續(xu)運(yun)行(xing)1小時.70%額定容(rong)量可連續(xu)運(yun)行(xing); 2、出廠試驗中短時工(gong)頻耐壓值(zhi)為1.1UN; 3、試驗變壓器(qi)在額定電(dian)壓下(xia)的局部放電(dian)量≤5pC.

無(wu)局部放(fang)電工頻(pin)試驗變(bian)壓(ya)器通過部級(ji)產(chan)品鑒(jian)定，主要技木(mu)性能處于地位，達(da)到同類產(chan)品的先進水平。

WDJF無局部(bu)(bu)放(fang)電(dian)(dian)試(shi)驗(yan)成套裝置主要用于互感(gan)器、電(dian)(dian)力變壓(ya)(ya)器、高(gao)壓(ya)(ya)斷路器、耦合電(dian)(dian)容器、電(dian)(dian)容套管、開關等試(shi)品進行(xing)工頻耐壓(ya)(ya)、局部(bu)(bu)放(fang)電(dian)(dian)及其他科學試(shi)驗(yan)研(yan)究。
