GDF-3000 DC System Earth Fault Detector
MuDc system, kune zvikanganiso zvakawanda zvepasi zvinosanganisira indirect earth fault, non-metal earth fault, loop earth fault, positive and negative earthing fault, positive and negative balance earth fault, multi-point earth fault.GDF-3000 Earth Fault Tester yeDC System inowana izvi zvikanganiso zvepasi uye inoratidza maparamendi emagetsi system, voltage yepasi, kuramba kwepasi uye kusagadzikana kwepasi kwemapazi nenzira kwayo.
●System pasi voltage kuyerwa basa, chiridzwa chinogona kuyera system pasi voltage, yakaipa kune yevhu voltage, system voltage, inogona kuwana 0-300V voltage yekutarisa renji.
●System insulation impedance kuyerwa basa, chiridzwa chinogona kuyera iyo yakanaka kune pasi insulation impedance uye yakaipa kune pasi insulation impedance yehurongwa.Inogona kuona kuyerwa kwe0-999KΩ.
●AC tambo yemagetsi yekuona basa, chiridzwa chinogona kutonga iyo AC tambo yekutadza kwemagetsi muDC system, uye inogona kuyera kukosha kwe AC voltage inopinda muDC system, iyo AC voltage kuyerwa renji i0-280V.
●Branch insulation impedance kuyerwa basa.Iyo chiridzwa inoyera yakanaka uye yakaipa pasi insulation impedance yebazi rega rega.
●Branch grounding fault point positioning function, chiridzwa chacho chinogona kuzadzisa chikanganiso chekumisa basa rebazi rekumisa kukanganisa.
●Ammeter basa, mudziyo unogona kushandiswa seyepamusoro-chaiyo ammeter, uye ikozvino kuyerwa kuyerwa kunogona kusvika 0.01mA.
●Ne-isina-signal ground rekutsvaga basa, chigadziro chinogona kutsvaga nzvimbo yepasi pasi pasina kupinza chero chiratidzo muhurongwa.
●Direction inoratidzira basa, yekuyedza bazi neinongedzo yepasi, chiridzwa chichava negwara rechiratidzo museve kuratidza hukama pakati penzvimbo yemushandisi uye nzvimbo yakawanikwa yekumisa, kuvandudza hunyanzvi hwekutsvaga.
●Insulation index analysis function, kana uchishandisa grounding function yekuona, mushure mekuona bazi, detector icharatidza insulation index yebazi rekushandisa uye kuongorora.
●Iyo waveform curve inoratidzira basa, kana uchishandisa detector kuona mamiriro ekudzivirira ebazi rakaedzwa, iyo inoratidzira inoratidza shanduko iripo yebazi rakayerwa nenzira yewaveform curve, iyo yakanakira mushandisi nekukurumidza uye nemazvo kuwana. mhosva.
●Iyo inotengeswa kunze kwenyika 16-bit microcontroller inoshandiswa seyo huru sisitimu.Iyo hardware dhizaini inonyatso kuenderana neakakodzera zviyero zvesimba uye electromagnetic kuenderana.Multiple redundancy nzira dzinogamuchirwa mukati kuti ive nechokwadi chekuvimbika kwechishandiso uye chishandiso chiri mukuyedzwa.
●Iyo yakakwira-chaiyo DC clamp mita inoshandiswa sechiratidzo chekutora chiratidzo, uye voltage sampling inotora yakakwirira-chaiyo analog-kusvika-digital shanduko chip, uye voltage uye impedance zvinoyerwa nemazvo.
●LCD kuratidza, ine hushamwari interface, yakajeka uye nyore kushanda.Ratidza insulation index zvakajeka uye chaiyo-nguva kuratidza waveform.Iyo inoratidza insulation level yematavi ese uye kutungamira kukanganisa kwepasi.
●Hungwaru kuona uye kuzivikanwa system.
●Iyo "analyzer" inogona kuona otomatiki iyo voltage level ye system, uye kuratidza ruzivo rweiyo insulation impedance nekukasira kana iyo insulation impedance yesystem yachinja.
●Mushure mekunge detector yawiriraniswa neruzivo rweanalyzer, haina kukanganiswa nekuona kureba;
●Kana iyo "detector" ichiongorora, iyo clamp inogona kusungirira tambo yemagetsi imwe chete, kana kusungirira tambo dzemagetsi akawanda kuti ivandudze kugona kwekuona;
●Mushure mekunge bvunzo ye "detector" yapedzwa, kana bazi rakaedzwa riine chikanganiso chekudzivirira, iyo nhungamiro yeruzivo rwenzvimbo yekukanganisa inotariswa.
●Iyo isina waya data data transmission module yakavakirwa pakati pe "analyzer" uye "detector" yekutaurirana, uye bvunzo basa uye kuratidza ruzivo rwakakwana, uye inogona kubata neakasiyana ekudzivirira kukanganisa mamiriro muDC system.
●Chishandiso chinogona kutsvaga nzvimbo yekukanganisa pasina kupinza chiratidzo muDC system.Mune iyo chiratidzo modhi, chishandiso chine ikozvino chinodzikamisa uye voltage kudzikamisa module, iyo isina mhedzisiro pane iyo DC system.
