GD2000B單相繼(ji)(ji)電保(bao)(bao)護試(shi)驗箱是一個新(xin)型智能化(hua)測試(shi)儀器(qi)微(wei)(wei)機(ji)繼(ji)(ji)電保(bao)(bao)護測試(shi)儀，以前的(de)繼(ji)(ji)電保(bao)(bao)護試(shi)驗工(gong)具主(zhu)要(yao)是用調壓器(qi)和移相器(qi)組合而成，體積笨重(zhong)，精度(du)不高，已不能滿足(zu)現代微(wei)(wei)機(ji)繼(ji)(ji)電保(bao)(bao)護的(de)校驗工(gong)作。隨(sui)著科學(xue)技術的(de)不斷(duan)發展，微(wei)(wei)機(ji)繼(ji)(ji)電保(bao)(bao)護已廣泛運用于線路保(bao)(bao)護，主(zhu)變(bian)差動保(bao)(bao)護，勵磁控制等各個領(ling)域，變(bian)電站綜合自動化(hua)已成為主(zhu)流(liu)。
現代(dai)微機(ji)繼電(dian)保(bao)護(hu)測試(shi)儀可分(fen)為(wei)兩(liang)種(zhong)(zhong)形式，一種(zhong)(zhong)是采用傳(chuan)統的OCL功放，體積大，重(zhong)(zhong)(zhong)量在(zai)25Kg左右，比較(jiao)笨重(zhong)(zhong)(zhong)，功放管工作在(zai)放大區，時(shi)間長了容易損壞，且動態范圍窄，精(jing)度不高(gao)。另一種(zhong)(zhong)是采用開關電(dian)源，功放采用數字功放，體積小，重(zhong)(zhong)(zhong)量輕，效率高(gao)，是繼電(dian)保(bao)護(hu)測試(shi)儀的發展方(fang)向。
繼電(dian)(dian)保護試驗箱可對(dui)各類(lei)型(xing)電(dian)(dian)壓、電(dian)(dian)流、頻率(lv)、功(gong)率(lv)、阻抗、諧波、差動(dong)(dong)(dong)、同期等繼電(dian)(dian)器以(yi)手動(dong)(dong)(dong)或(huo)自動(dong)(dong)(dong)方式進行(xing)(xing)測試，可模擬各種故障類(lei)型(xing)進行(xing)(xing)距離、零序(xu)保護裝(zhuang)置定值校驗和(he)保護裝(zhuang)置的整組試驗，可自動(dong)(dong)(dong)掃描微機(ji)和(he)數(shu)字型(xing)變壓器、發變組差動(dong)(dong)(dong)保護比率(lv)制動(dong)(dong)(dong)曲線，具備GPS觸發功(gong)能。
