三倍頻(pin)電(dian)源發生器是為了滿足GB1094.3—85、GB1207和(he)電(dian)氣設備預防性試(shi)驗(yan)(yan)(yan)(yan)(yan)規程—1995中三倍頻(pin)感(gan)應耐(nai)壓試(shi)驗(yan)(yan)(yan)(yan)(yan)和(he)局放試(shi)驗(yan)(yan)(yan)(yan)(yan)而設計。 變(bian)壓器、互(hu)感(gan)器感(gan)應耐(nai)壓試(shi)驗(yan)(yan)(yan)(yan)(yan)是檢驗(yan)(yan)(yan)(yan)(yan)該產品是否(fou)符(fu)合國家標準(zhun)的一(yi)項重(zhong)要(yao)(yao)(yao)試(shi)驗(yan)(yan)(yan)(yan)(yan)。繞(rao)組(zu)的層間(jian)、匝間(jian)、段及相間(jian)絕緣的縱絕緣感(gan)應試(shi)驗(yan)(yan)(yan)(yan)(yan)，是考驗(yan)(yan)(yan)(yan)(yan)繞(rao)組(zu)是否(fou)符(fu)合要(yao)(yao)(yao)求的一(yi)個重(zhong)要(yao)(yao)(yao)項目。為了提高(gao)繞(rao)組(zu)試(shi)驗(yan)(yan)(yan)(yan)(yan)電(dian)壓，使(shi)變(bian)壓器或(huo)互(hu)感(gan)器的鐵芯又不致于過(guo)飽和(he)導致勵(li)磁電(dian)流過(guo)大，因此要(yao)(yao)(yao)使(shi)試(shi)驗(yan)(yan)(yan)(yan)(yan)頻(pin)率提高(gao)，一(yi)般為10
