GDF-5000 Online Insulation Monitoring Device rau DC System
GDF-5000/OL Online Insulation Monitoring Device rau DC System yog siv rau lub sijhawm hauv online saib xyuas kev rwb thaiv tsev ntawm DC tsheb npav thiab ceg.Cov cuab yeej no siv txoj kev tshawb pom ntawm DC sib npaug tiv thaiv.Nws tsis tsim ib qho AC lossis DC cuam tshuam teeb liab rau busbar, thiab yuav tsis ua rau cov khoom siv hluav taws xob tsis zoo.Nws yog haum rau cov nroj tsuag fais fab thiab substations ntawm txhua theem voltage.
GDF-5000 / OL qhov tshwj xeeb ruaj khov thiab tiv thaiv kev faib tawm ua rau nws tsim nyog rau lub tsheb npav nyob rau hauv kev ua haujlwm nyuaj, cov qauv ntsuas, compact loj, yooj yim installation thiab siv tau zoo dua.
GDF-5000/OL muaj LCD zaub, tag nrho software muaj nuj nqi tswj, zoo meej txiv neej-tshuab interface, yooj yim lag luam thiab siv.
●Modular thoob ntiaj teb tus qauv muaj xws li cov qauv, qauv plhaub, me me thiab lub teeb yuag, yooj yim installation thiab txij nkawm;
●Ib leeg / ob lub tsheb npav mus txog 64 lub voj voog saib xyuas, DC sib npaug tiv thaiv txoj kev tshawb nrhiav, tsis muaj kev cuam tshuam tsheb npav;
●Ceg ceev nrhiav kom pom, lub sijhawm tshuaj xyuas tsawg dua 20 vib nas this;
●Cov txiaj ntsig ntsuas tsis muaj feem cuam tshuam nrog lub npav faib cov peev txheej;
●Tsis siv neeg / phau ntawv tshuaj xyuas cov ceg;
●Kev teeb tsa ntawm DC to tam sim no sensor yog hloov tau thiab yooj yim.
●Kev sib txuas lus RS-485 kev sib txuas lus, MODBUS / Emerson kev sib txuas lus raws tu qauv yog sib xws;
●Muaj kev khiav hauj lwm kub ntau yam;
