GDF-3000 DC System Earth Fault Detector
Mu dongosolo la DC, pali zolakwika zambiri zapadziko lapansi kuphatikiza zolakwika zapadziko lapansi zosalunjika, zolakwika zapadziko lapansi zopanda zitsulo, zolakwika za loop lapansi, zolakwika zapadziko lapansi, zabwino ndi zoyipa zapadziko lapansi, cholakwika chabwino ndi cholakwika padziko lapansi, cholakwika chamitundu yambiri.GDF-3000 Earth Fault Tester ya DC System imapeza zolakwika zapadziko lapansi ndikuwonetsa magawo amagetsi amagetsi, mphamvu yapadziko lapansi, kukana kwa nthaka ndi kusakhazikika kwanthambi molondola.
●Dongosolo pansi voteji kuyeza ntchito, chida akhoza kuyeza dongosolo pansi voteji, zoipa pansi voteji, dongosolo voteji, akhoza kukwaniritsa 0-300V voteji kuwunika osiyanasiyana.
●System kutchinjiriza Impedans muyeso ntchito, chida akhoza kuyeza zabwino kuti nthaka kutchinjiriza impedance ndi zoipa pansi kutchinjiriza impedance dongosolo.Itha kuzindikira muyeso wa 0-999KΩ.
●Chingwe cha AC chowunikira magetsi, chidachi chimatha kuweruza kulephera kwamagetsi kwa chingwe cha AC mu dongosolo la DC, ndipo chimatha kuyeza mtengo wamagetsi wa AC womwe umalowa mu dongosolo la DC, muyeso wamagetsi a AC ndi 0-280V.
●Nthambi insulation impedance muyeso ntchito.Chidacho chimayesa kutsekereza kwabwino komanso koyipa kwanthambi iliyonse.
●Nthambi grounding cholakwa mfundo udindo ntchito, chida akhoza kukwaniritsa grounding cholakwa mfundo udindo ntchito ya nthambi grounding kulakwa.
●Ammeter ntchito, chipangizochi chingagwiritsidwe ntchito ngati ammeter yolondola kwambiri, ndipo kusamvana kwamakono kumatha kufika 0.01mA.
●Ndi ntchito yosakira pansi yopanda chizindikiro, chipangizochi chikhoza kupeza malo olakwika popanda kulowetsa chizindikiro chilichonse mu dongosolo.
●Ntchito yowonetsera mayendedwe, poyesa nthambi ndi chisonyezero chapansi, chidacho chidzakhala ndi muvi wolozera kuti zisonyeze momwe wogwiritsa ntchitoyo akuyambira ndi malo omwe apezeka, kuti azitha kufufuza bwino.
●Ntchito yowunikira insulation index, mukamagwiritsa ntchito kuzindikira koyambira, mutatha kuzindikira nthambi, chowunikiracho chidzawonetsa index yotsika ya nthambi kuti igwiritsidwe ntchito ndikuwunika.
●Ntchito yowonetsera ma waveform curve, mukamagwiritsa ntchito chowunikira kuti muwone momwe nthambi yoyesedwa imakhalira, chiwonetserochi chikuwonetsa kusintha kwaposachedwa kwa nthambi yoyezedwa ngati mawonekedwe a curve waveform, yomwe ndi yabwino kuti wosuta apeze mwachangu komanso molondola. vuto.
●16-bit microcontroller yotumizidwa kunja imagwiritsidwa ntchito ngati dongosolo lalikulu.Mapangidwe a Hardware amagwirizana kwambiri ndi milingo yoyenera yamagetsi ndi ma elekitiroma.Njira zingapo zochepetsera ntchito zimatengedwa mkati kuti zitsimikizire kudalirika kwa chipangizocho ndi chipangizocho poyesedwa.
●Makina owongolera kwambiri a DC amagwiritsidwa ntchito ngati gawo lopezera ma siginecha, ndipo zitsanzo za voteji zimatengera kutembenuka kwapamwamba kwambiri kwa analogi kupita ku digito, ndipo voteji ndi kulepheretsa zimayesedwa molondola.
●Chiwonetsero cha LCD, chokhala ndi mawonekedwe ochezeka, omveka bwino komanso osavuta.Onetsani insulation index momveka bwino komanso mawonekedwe a nthawi yeniyeni.Imawonetsa mulingo wa insulation wa nthambi zonse ndi njira yolakwika ya dziko lapansi.
●Dongosolo lozindikira komanso kuzindikira mwanzeru.
●"Analyzer" imatha kuzindikira mphamvu yamagetsi yamagetsi, ndikuwonetsa zambiri za insulation impedance mwachangu pomwe kutsekeka kwa dongosolo kumasintha.
●Chowunikiracho chikalumikizidwa ndi chidziwitso cha analyzer, sichimakhudzidwa ndi mtunda wodziwika;
●"Chowunikira" chikayang'ana, chotchingacho chimatha kukakamiza chingwe chimodzi chamagetsi, kapena kumangitsa zingwe zamagetsi zingapo kuti zizindikire bwino;
●Pambuyo poyezetsa "detector" ikamalizidwa, ngati nthambi yoyesedwa ili ndi vuto la kusungunula, chiwongolero cha malo olakwika okhudzana ndi mayesero amatsimikiziridwa.
●Magawo otumizira ma data opanda zingwe amamangidwa pakati pa "analyzer" ndi "detector" yolumikizirana, ndipo ntchito yoyeserera ndi chidziwitso chowonetsera zatha, ndipo imatha kuthana ndi zolakwika zosiyanasiyana mu dongosolo la DC.
●Chipangizocho chimatha kupeza pomwe pali cholakwika popanda kubaya chizindikiro mu DC system.M'mawonekedwe azizindikiro, chipangizocho chili ndi gawo lochepetsera pakali pano komanso gawo lochepetsa mphamvu yamagetsi, lomwe silimakhudza dongosolo la DC.
