GDF-5000 Online Insulation Monitoring Device yeDC System
GDF-5000/OL Online Insulation Monitoring Device yeDC Sisitimu inoshandiswa pa online-chaiyo yekutarisisa mamiriro ekudzivirira eDC bhazi nebazi.Ichi chishandiso chinotora nzira yekuona yeDC yakadzikama kuramba.Iyo haiburitse chero AC kana DC yekukanganisa chiratidzo kune bhasibar, uye haizokonzerese kudonha kwekudzivirira kwekudzivirira.Inokodzera zvidyarwa zvemagetsi uye substations yechero voltage level.
GDF-5000/OL's yakasarudzika kugadzikana uye anti-kugovera capacitance inoita kuti ive yakakodzera kune bhazi system pasi pemamiriro akaomarara ekushanda, yakajairwa chiridzwa chimiro, compact size, kugadzika kuri nyore uye kushanda zviri nani.
GDF-5000/OL ine LCD kuratidza, yakazara software basa rekutonga, yakakwana man-muchina interface, nyore kushanda uye kushandisa.
●Modular yepasi rose yakajairwa maindasitiri controller chimiro, yakajairwa goko, diki saizi uye huremu huremu, kuisirwa nyore uye kugadzirisa;
●Single/double bhazi kusvika ku64 loop monitoring, DC yakaringana kuramba yekuona nzira, hapana kukanganiswa kwebhazi;
●Bazi rinokurumidza kuona, nguva yekuongorora isingasviki 20 seconds;
●Mhedzisiro yakayerwa haina hukama nebhazi rakagoverwa capacitance;
●Otomatiki/manual kuongorora mapazi;
●Iko kumisikidzwa kweDC leakage ikozvino sensor inochinjika uye iri nyore.
●Isolated RS-485 yekutaurirana interface, MODBUS/Emerson kutaurirana protocol inoenderana zvizere;
●Industrial tembiricha yekushanda siyana;
