10KVA/500型三倍頻感應電壓(ya)發生器裝置

1、概述：

本產(chan)品是(shi)在工頻(pin)電網中利用硅(gui)鋼片鐵心的磁(ci)化曲線飽和特(te)性，在變壓器接(jie)成(cheng)開口三角形的二次(ci)線圈中感應出零序三次(ci)諧波電勢(shi)的原理制成(cheng)的輕(qing)便型測試設備(bei)。

10KVA/500型三倍(bei)頻(pin)感應(ying)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)發生器裝置可配套提供連同(tong)控制設備及機箱在內(nei)的成套產品(pin)。本發生器是(shi)電(dian)(dian)(dian)(dian)力(li)(li)系統、發電(dian)(dian)(dian)(dian)廠、變(bian)電(dian)(dian)(dian)(dian)站、供配電(dian)(dian)(dian)(dian)網絡中對小容量電(dian)(dian)(dian)(dian)力(li)(li)變(bian)壓(ya)(ya)(ya)器：串(chuan)級式高壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)互感器進行(xing)倍(bei)頻(pin)感應(ying)高壓(ya)(ya)(ya)試(shi)驗的基本設備之一(yi)。也可對各種低壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)子(zi)、儀表(biao)電(dian)(dian)(dian)(dian)源(yuan)變(bian)壓(ya)(ya)(ya)器，電(dian)(dian)(dian)(dian)感線(xian)圈電(dian)(dian)(dian)(dian)器線(xian)圈進行(xing)倍(bei)頻(pin)倍(bei)壓(ya)(ya)(ya)試(shi)驗，同(tong)時也可作為功率不大于1千瓦的倍頻電(dian)(dian)(dian)源用于某些特殊電(dian)(dian)(dian)器設(she)備的供電(dian)(dian)(dian)或測(ce)試。

本產品是靜止變(bian)頻(pin)設備、噪(zao)音低、體積(ji)小、在高電壓(ya)系統(tong)中*可以取(qu)代傳統(tong)的變(bian)頻(pin)機組。

2、10KVA/500型三倍(bei)頻(pin)感應(ying)電壓發生(sheng)器(qi)裝置工作原理：

三(san)臺單相變壓器一(yi)次(ci)側接(jie)成星形，二次(ci)側接(jie)成開口三(san)角形，在一(yi)次(ci)側加上對稱(cheng)的(de)三(san)相正弦波(bo)(bo)電源時，并升高電壓讓鐵芯(xin)磁路(lu)飽和，使(shi)鐵芯(xin)中磁通所含(han)三(san)次(ci)諧(xie)波(bo)(bo)的(de)成分增多,相(xiang)應在鐵芯線圈(quan)上感應三次諧(xie)波電壓也(ye)增高.

由開口三角(jiao)形的(de)發生器二(er)次(ci)側輸出(chu)的(de)這個150赫(he)茲（三倍(bei)工頻）感(gan)應電(dian)(dian)壓即(ji)作為三倍(bei)頻試驗電(dian)(dian)源電(dian)(dian)壓。

當三倍頻發生器(qi)帶上（例如JCC——220型高壓(ya)串級式(shi)電(dian)壓(ya)互(hu)感器）負載時，其電(dian)流由感性變(bian)為(wei)容性，由于功率因(yin)數低的(de)影響，使發(fa)生器的(de)效率較低，一般只有20%左右。因此，可在被試(shi)(shi)品某(mou)一空(kong)繞(rao)組上接入電抗器進行電流補(bu)償。來提高(gao)整個試(shi)(shi)驗回路(lu)的功率(lv)因數(shu)。
