RVR動態(tai)電(dian)(dian)壓(ya)(ya)恢復器采(cai)用電(dian)(dian)力電(dian)(dian)子技(ji)術(shu)，設(she)備(bei)采(cai)用模(mo)塊化功(gong)率單元設(she)計，是一種離線式并聯動態(tai)電(dian)(dian)壓(ya)(ya)暫(zan)降保護產品，設(she)備(bei)利用能量(liang)轉換技(ji)術(shu)，以超級電(dian)(dian)容作(zuo)為(wei)儲能單元，在電(dian)(dian)網電(dian)(dian)壓(ya)(ya)降低(di)時進(jin)行快速電(dian)(dian)壓(ya)(ya)補償，保證設(she)備(bei)下游負載電(dian)(dian)壓(ya)(ya)有(you)效值不受到影響。

工作原理：

設(she)備(bei)分為(wei)電(dian)(dian)網(wang)分離器、儲(chu)能(neng)逆變器和儲(chu)能(neng)單元三部分，當電(dian)(dian)網(wang)電(dian)(dian)壓正(zheng)常(chang)是(shi)負載(zai)通過電(dian)(dian)網(wang)分離器進(jin)行供(gong)電(dian)(dian)，當電(dian)(dian)網(wang)電(dian)(dian)壓超過110%或低于90%時，設(she)備(bei)通過儲(chu)能(neng)逆變器利用儲(chu)能(neng)單元的能(neng)量為(wei)負載(zai)進(jin)行供(gong)電(dian)(dian)。整個補償動作不超過5ms，保(bao)證(zheng)負載(zai)在電(dian)(dian)壓異常(chang)時正(zheng)常(chang)運行。

主要功能：

補償電壓(ya)殘值為0~90%的電壓(ya)暫降

補償110~130%的電壓驟(zou)升

大(da)于(yu)98%的整體系統效率(lv)

采用超級電容作為儲能器件循環壽命(ming)大(da)于10萬次(ci)
