一旦發(fā)生電弧光故障,這一裝置可以迅速可靠動(dòng)作,切除故障電源,準(zhǔn)確定位故障點(diǎn)。對(duì)于變電所、大型企業(yè)用電的各種運(yùn)行方式,可以具體情況和客戶需要靈活配置,適應(yīng)性強(qiáng)。JD9900B電弧光保護(hù)綜合測(cè)控系統(tǒng)是我公司根據(jù)市場(chǎng)需要開(kāi)發(fā)的新一代產(chǎn)品,系統(tǒng)動(dòng)作準(zhǔn)確,反應(yīng)靈敏,可靠性高。JD9900B采用分布式模式設(shè)計(jì),適合作為中低壓母線保護(hù),具備靈活的組**性。其中饋線保護(hù)單元可**形成**小化保護(hù)系統(tǒng),單獨(dú)保護(hù)饋線以減小***停電范圍。饋線單元也可運(yùn)行于集中監(jiān)控模式,通過(guò)某一主單元與調(diào)度通信。JD9900B
