、概述

根據IEC及(ji)國家(jia)有關規(gui)定，變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)生產過程中(zhong)的(de)(de)半(ban)成品和(he)成品以(yi)及(ji)新安裝和(he)檢(jian)修(xiu)后的(de)(de)變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)在投運前必須進行變(bian)(bian)(bian)(bian)壓(ya)(ya)比測試(shi)。在《電力(li)設備交(jiao)接和(he)預(yu)防通過對(dui)性試(shi)驗規(gui)程》中(zhong)也要求對(dui)運行的(de)(de)變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)定期進行變(bian)(bian)(bian)(bian)比的(de)(de)測定。變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)的(de)(de)變(bian)(bian)(bian)(bian)比測試(shi)，可以(yi)檢(jian)查變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)的(de)(de)繞組、分接開關的(de)(de)狀況,判斷變(bian)(bian)(bian)(bian)壓(ya)(ya)器(qi)是(shi)否存(cun)在線圈短(duan)(duan)路、連(lian)接錯誤、匝(za)間短(duan)(duan)路等(deng)缺陷，從而保證(zheng)設備的(de)(de)安全使(shi)用。

揚(yang)州科拓電氣科技有限公(gong)(gong)司公(gong)(gong)司研制生產的(de)(de)變(bian)(bian)壓(ya)(ya)器(qi)(qi)變(bian)(bian)比(bi)測(ce)試(shi)儀采用64位ARM內(nei)核作為處理(li)的(de)(de)核心，對整機進行控制。實現了(le)單(dan)相或(huo)三相變(bian)(bian)壓(ya)(ya)器(qi)(qi)的(de)(de)變(bian)(bian)比(bi)測(ce)量的(de)(de)次完(wan)成。儀器(qi)(qi)的(de)(de)操(cao)作全部用中文菜(cai)單(dan)顯(xian)示(shi)，簡單(dan)直(zhi)觀。測(ce)試(shi)結果(guo)準確可靠，并且(qie)能夠(gou)存(cun)儲和打印測(ce)試(shi)結果(guo)。抗干擾能力強。能夠(gou)滿足各(ge)種大中小型變(bian)(bian)壓(ya)(ya)器(qi)(qi)變(bian)(bian)比(bi)測(ce)試(shi)的(de)(de)需要。
