本產品(pin)用(yong)于(yu)電力變(bian)壓(ya)(ya)器、電壓(ya)(ya)互感器等被試(shi)品(pin)，除了要對(dui)全絕(jue)(jue)緣(yuan)(yuan)變(bian)壓(ya)(ya)器的(de)主絕(jue)(jue)緣(yuan)(yuan)進行(xing)外施工頻高(gao)壓(ya)(ya)試(shi)驗外，而且還要對(dui)變(bian)壓(ya)(ya)器的(de)縱絕(jue)(jue)緣(yuan)(yuan)以(yi)及半(ban)絕(jue)(jue)緣(yuan)(yuan)變(bian)壓(ya)(ya)器的(de)主絕(jue)(jue)緣(yuan)(yuan)進行(xing)感應高(gao)壓(ya)(ya)試(shi)驗。
    根據(ju)國家試驗標準(zhun)，對電(dian)(dian)(dian)力變壓(ya)(ya)(ya)器(qi)及電(dian)(dian)(dian)壓(ya)(ya)(ya)互感器(qi)感應試驗電(dian)(dian)(dian)壓(ya)(ya)(ya)大(da)致2-3倍(bei)zui大(da)工作相(xiang)電(dian)(dian)(dian)壓(ya)(ya)(ya)考慮(lv)。*，變壓(ya)(ya)(ya)器(qi)在額定頻(pin)(pin)率，額定電(dian)(dian)(dian)壓(ya)(ya)(ya)下，鐵芯(xin)接近飽和，若用(yong)工頻(pin)(pin)電(dian)(dian)(dian)源(yuan)在被試變壓(ya)(ya)(ya)器(qi)繞組兩端(duan)施加大(da)于額定電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)試驗電(dian)(dian)(dian)壓(ya)(ya)(ya)，則空(kong)載勵磁電(dian)(dian)(dian)流會急劇增加，達(da)到不可允(yun)許(xu)的(de)程度，從感應電(dian)(dian)(dian)勢的(de)關系式可以看出，為了(le)施加大(da)于額定電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)試驗電(dian)(dian)(dian)壓(ya)(ya)(ya)，而又不使鐵芯(xin)飽和，可采(cai)用(yong)增加電(dian)(dian)(dian)源(yuan)頻(pin)(pin)率的(de)辦法，必(bi)須(xu)用(yong)大(da)于倍(bei)頻(pin)(pin)電(dian)(dian)(dian)源(yuan)發生器(qi)。
