GDF-5000 Online Insulation Monitoring Device bakeng sa DC System
GDF-5000/OL Online Insulation Monitoring Device for DC System e sebelisoa bakeng sa tlhahlobo ea nako ea nnete ea marang-rang ea boemo ba ho kenya letsoho ba bese ea DC le lekala.Sesebelisoa sena se nka mokhoa oa ho lemoha oa DC ho hanyetsa ho leka-lekaneng.Ha e hlahise lets'oao la tšitiso ea AC kapa DC ho busbar, 'me e ke ke ea baka ho theoha ha khanyetso ea maiketsetso ea maiketsetso.E loketse limela tsa motlakase le li-substations tsa boemo leha e le bofe ba motlakase.
Botsitso bo ikhethang ba GDF-5000 / OL le bokhoni bo khahlanong le ho ajoa bo etsa hore e tšoanelehe haholoanyane bakeng sa tsamaiso ea libese tlas'a maemo a thata a ho sebetsa, sebopeho sa lisebelisoa tse tloaelehileng, boholo ba lik'hamphani, ho kenngoa ha bonolo le ho sebetsa hantle.
GDF-5000/OL e na le ponts'o ea LCD, taolo e felletseng ea ts'ebetso ea software, sebopeho se phethahetseng sa mochini oa motho, ts'ebetso e bonolo le ts'ebeliso.
●Sebopeho sa taolo ea indasteri e tloaelehileng ea machaba, khetla e tloaelehileng, boholo bo nyane le boima bo bobebe, ho kenya le ho hlokomela habonolo;
●Bese e le 'ngoe / habeli ho fihla ho 64 loop monitoring, DC mokhoa o leka-lekaneng oa ho lemoha, ha ho na tšitiso ea libese;
●Ho lemoha ka potlako ea lekala, nako ea ho hlahloba e ka tlase ho metsotsoana e 20;
●Liphetho tse lekantsoeng ha li amane le matla a kabo ea libese;
●Ho hlahloba makala ka boiketsetso/ka letsoho;
●Ho hlophisoa ha sensor ea hona joale ea leakage ea DC hoa fetoha ebile ho bonolo.
●Sehokelo sa puisano sa RS-485 se ikhethileng, protocol ea puisano ea MODBUS/Emerson e lumellana ka botlalo;
●Mocheso oa mocheso oa indasteri;
