產品用途描述

三倍(bei)頻發生器用于電力變壓器、電壓互感(gan)器等被試品，除了要對全絕(jue)緣(yuan)變壓器的主(zhu)絕(jue)緣(yuan)進(jin)行外(wai)(wai)施(shi)工頻高壓試驗外(wai)(wai)，而(er)且還要對變壓器的縱(zong)絕(jue)緣(yuan)以(yi)及半絕(jue)緣(yuan)變壓器的主(zhu)絕(jue)緣(yuan)進(jin)行感(gan)應高壓試驗。

產品簡介

SBF三倍頻(pin)(pin)發生器(qi)(qi)用(yong)于電(dian)力變壓器(qi)(qi)、電(dian)壓互感器(qi)(qi)等被試品，除了要對全(quan)絕(jue)緣(yuan)變壓器(qi)(qi)的(de)(de)(de)主絕(jue)緣(yuan)進行(xing)外(wai)施(shi)工(gong)頻(pin)(pin)高壓試驗外(wai)，而且還要對變壓器(qi)(qi)的(de)(de)(de)縱絕(jue)緣(yuan)以(yi)及(ji)半絕(jue)緣(yuan)變壓器(qi)(qi)的(de)(de)(de)主絕(jue)緣(yuan)進行(xing)感應高壓試驗。 根據國家(jia)試驗標準要求，對(dui)電(dian)力變壓器及電(dian)壓互(hu)感器感應試驗電(dian)壓大致(zhi)2-3倍zui大(da)(da)工作相電(dian)(dian)(dian)(dian)(dian)壓考(kao)慮(lv)。*，變壓器在額定(ding)(ding)頻(pin)(pin)率(lv)，額定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)壓下，鐵芯接近(jin)飽(bao)和(he)，若(ruo)用工頻(pin)(pin)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)在被試(shi)變壓器繞組兩端(duan)施加大(da)(da)于(yu)額定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)壓的試(shi)驗電(dian)(dian)(dian)(dian)(dian)壓，則空載勵磁電(dian)(dian)(dian)(dian)(dian)流會急劇增(zeng)加，達到不可(ke)允許的程度，從感(gan)應電(dian)(dian)(dian)(dian)(dian)勢(shi)的關系式可(ke)以(yi)看(kan)出，為了施加大(da)(da)于(yu)額定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)壓的試(shi)驗電(dian)(dian)(dian)(dian)(dian)壓，而(er)又(you)不使(shi)鐵芯飽(bao)和(he)，可(ke)采用增(zeng)加電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)頻(pin)(pin)率(lv)的辦法(fa)，必須用大(da)(da)于(yu)倍頻(pin)(pin)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)發生器。
