ʻO GDF-5000 Pūnaewele Hoʻokolo Pūnaewele no ka Pūnaehana DC
Hoʻohana ʻia ʻo GDF-5000/OL Online Insulation Monitoring Device no DC System no ka nānā ʻana ma ka pūnaewele i ka manawa maoli o ke kūlana insulation o ka pahi DC a me ka lālā.Hoʻohana kēia hāmeʻa i ke ala ʻike o ka pale kaulike DC.ʻAʻole ia e hoʻopuka i kahi hōʻailona hoʻopilikia AC a DC paha i ka busbar, a ʻaʻole ia e hoʻohaʻahaʻa i ka hoʻohaʻahaʻa ʻana o ka insulation.He kūpono ia no nā mea kanu mana a me nā substation o kēlā me kēia pae uila.
ʻO ke kūpaʻa kūʻokoʻa o GDF-5000/OL a me ka capacitance anti-distributed e ʻoi aku ka maikaʻi no ka ʻōnaehana kaʻa ma lalo o nā kūlana hana paʻakikī, ke ʻano mea kani maʻamau, ka nui paʻa, ka hoʻonohonoho kūpono a me ka hoʻopili maikaʻi ʻana.
Loaʻa iā GDF-5000/OL ka hōʻike LCD, ka mana o ka polokalamu lako polokalamu piha, ka pilina kanaka-mīkini kūpono, ka hana maʻalahi a me ka hoʻohana.
●ʻO ka ʻōnaehana hoʻokele ʻenehana maʻamau modular honua, ka pūpū maʻamau, ka liʻiliʻi liʻiliʻi a me ke kaumaha māmā, hoʻonohonoho maʻalahi a mālama ʻia;
●Kaʻa kaʻa hoʻokahi/pālua a hiki i ka nānā ʻana i ka loop loop 64, ke ʻano ʻike pale pale kaulike DC, ʻaʻohe pilikia kaʻa;
●ʻO ka ʻike wikiwiki o ka lālā, ʻoi aku ka manawa o ka nānā ʻana ma mua o 20 kekona;
●ʻAʻole pili nā hopena i ana ʻia me ka capacitance puʻunaue kaʻa;
●Nānā 'akomi/manu'a o nā lālā;
●ʻO ka hoʻonohonoho o ka DC leakage sensor i kēia manawa he maʻalahi a maʻalahi.
●Hoʻokaʻawale ʻia ke kikowaena kamaʻilio RS-485, ʻo MODBUS/Emerson kaʻina kamaʻilio kūpono loa;
●ʻO ka pae wela hana ʻoihana;
