Interturn short - circuit protection equipment and relays for generators 發(fā)電機(jī)匝間短路保護(hù)裝置及繼電器
Lnb power short - circuit protection Lnb電源短路保護(hù)
Automatic short - circuit protection 自動(dòng)短路保護(hù)
Short - circuit protection for electric coaldrill transformer based on carrier - frequency principle 用載頻原理對(duì)煤電鉆變壓器作短路保護(hù)
This machine adopt the high - quality relay and the fleetness rectifier tube , the full - automatic short - circuit protection implement , operation nimble , use safety simplely reliably 本機(jī)采用高品質(zhì)繼電器及快速整流管,全自動(dòng)短路保護(hù)器,操作簡(jiǎn)單靈活,使用安全可靠。
This product is perfect for lighting and temperature control and over - current , short - circuit protection systems ; a high - pressure type ring network ( including dual - supply ) , terminal type ; measurement methods are low - voltage or high - pressure measurement , change layout box " goods " , " eye " type , the body or an integrated one 本產(chǎn)品具有照明及完善的溫控及過(guò)流、短路保護(hù)系統(tǒng);高壓有環(huán)網(wǎng)型(包括雙電源) 、終端型,計(jì)量方式有高壓或低壓計(jì)量,箱變布置有“品” 、 “目”型,分體或一體式。
It has been verified by simulation tests that the symmetric short - circuit protection can not only avoid the starting current but also achieve higher sensibility ; unbalance protection can distinguish unbalance short - circuit and loss of phase . the operation parameters of other protective functions has all reached the design requirements 短路保護(hù)既能躲過(guò)起動(dòng)電流,又有較高的靈敏度;不平衡保護(hù),能準(zhǔn)確區(qū)分不對(duì)稱短路和斷相故障;其它保護(hù)功能的動(dòng)作指標(biāo)均達(dá)到了設(shè)計(jì)要求。
