I-GDF-3000 DC System Fault Detector
Ohlelweni lwe-DC, kunamaphutha amaningi omhlaba okuhlanganisa iphutha lomhlaba elingaqondile, iphutha lomhlaba elingelona insimbi, iphutha lomhlaba oyiluphu, iphutha eliqondile nelibi elibi, ibhalansi elungile nengalungile iphutha lomhlaba, iphutha lomhlaba elinamaphuzu amaningi.I-GDF-3000 Earth Fault Tester Yesistimu ye-DC ithola lawa maphutha omhlaba futhi ibonise amapharamitha we-voltage yesistimu, amandla kagesi omhlaba, ukumelana nomhlaba kanye nokukhinyabezeka komhlaba kwamagatsha ngokunembile.
●Umsebenzi wokulinganisa amandla kagesi wesistimu, ithuluzi lingalinganisa i-voltage yaphansi yesistimu, i-negative kuya ku-voltage yaphansi, i-voltage yesistimu, ingafinyelela uhla lokuqapha amandla ka-0-300V.
●Umsebenzi wokulinganisa we-insulation impedance wesistimu, ithuluzi lingakala i-positive to ground insulation impedance kanye ne-negative to ground insulation impedance yesistimu.Ingabona isilinganiso esingu-0-999KΩ.
●Umsebenzi wokuthola ugesi wentambo ye-AC, ithuluzi lingahlulela ukwehluleka kukagesi kweyunithi yezinhlamvu ze-AC ohlelweni lwe-DC, futhi lingakala inani le-voltage ye-AC engena ohlelweni lwe-DC, ububanzi bokulinganisa i-AC voltage ngu-0-280V.
●Umsebenzi wokulinganisa i-impedance yegatsha.Ithuluzi likala i-positive kanye ne-negative ye-insulation yomhlabathi yegatsha ngalinye.
●Umsebenzi wokumisa iphuzu lesisekelo segatsha, ithuluzi lingafinyelela umsebenzi wokuma wephuzu eliphansi lephutha lesisekelo legatsha.
●Umsebenzi we-ammeter, idivayisi ingasetshenziswa njenge-ammeter enembayo ephezulu, futhi ukulungiswa kwamanje kokulinganisa kungafinyelela ku-0.01mA.
●Ngomsebenzi wokusesha ongekho esignali, idivayisi ingathola indawo yephutha ngaphandle kokujova noma iyiphi isignali kusistimu.
●Umsebenzi wokubonisa isiqondiso, ukuze kuhlolwe igatsha ngenkomba yaphansi, ithuluzi lizoba nomcibisholo wenkomba yesiqondiso ukuze ubonise ukuqondiswa okuhlobene phakathi kwendawo ephansi yomsebenzisi nendawo ephansi etholiwe, ukuze kuthuthukiswe ukusebenza kahle kosesho.
●Umsebenzi wokuhlaziya inkomba ye-insulation, lapho usebenzisa ukutholwa kokusebenza okuphansi, ngemva kokuthola igatsha, umtshina uzobonisa inkomba yokuhlukanisa yegatsha ukuze kusetshenziswe ireferensi nokuhlaziya.
●Umsebenzi wokubonisa ijika le-waveform, lapho usebenzisa umtshina ukuthola isimo sokwaleka segatsha elihloliwe, isibonisi sizobonisa ushintsho lwamanje lwegatsha elilinganisiwe ngendlela yejika le-waveform, elilungele umsebenzisi ukuthi alithole ngokushesha nangokunembile. iphuzu lephutha.
●I-microcontroller engenisiwe engu-16-bit isetshenziswa njengesistimu eyinhloko.Idizayini yehadiwe ihambisana ngokuqinile nezindinganiso ezifanele zamandla nokuhambisana kwe-electromagnetic.Izindlela eziningi zokuphinda zisetshenziswe zamukelwa ngaphakathi ukuze kuqinisekiswe ukwethembeka kwedivayisi kanye nedivayisi ngaphansi kokuhlolwa.
●Imitha ye-clamp ye-DC enembayo ephezulu isetshenziswa njengeyunithi yokutholwa kwesignali, futhi isampula ye-voltage isebenzisa i-chip yokuguqula ye-analog-to-digital enembayo ephezulu, futhi i-voltage ne-impedance kukalwa ngokunembile.
●Isibonisi se-LCD, esinokuxhumana okunobungane, ukusebenza okucacile nokulula.Bonisa inkomba ye-insulation ngokugqamile nangesikhathi sangempela sokubonisa i-waveform.Ibonisa izinga lokufakelwa kwawo wonke amagatsha kanye nesiqondiso sephutha lomhlaba.
●Uhlelo lokutholwa okuhlakaniphile nokuqashelwa.
●"I-analyzer" ingakwazi ukuhlonza ngokuzenzakalelayo izinga le-voltage yesistimu, futhi ibonise ulwazi lwe-impedance ye-insulation ngokushesha lapho i-insulation impedance yesistimu ishintsha.
●Ngemva kokuba umtshina usuvunyelaniswe nolwazi lwe-analyzer, awuthintwa ibanga lokutholwa;
●Uma "umtshina" uhlola, i-clamp ingacindezela intambo yamandla eyodwa, noma ibambe izintambo eziningi zamandla ukuze kuthuthukiswe ukusebenza kahle kokutholwa;
●Ngemuva kokuthi ukuhlolwa "komtshina" sekuqediwe, uma igatsha elihloliwe linephutha lokuhlukanisa, ulwazi lwesiqondiso sephuzu lephutha elihlobene nephuzu lokuhlola liyanqunywa.
●Imojula yokudlulisa idatha engenantambo yakhiwe phakathi kwe-"analyzer" kanye "nomtshina" ukuze kuxhunyanwe, futhi umsebenzi wokuhlola nolwazi lokubonisa kuphelile, futhi ingabhekana nezimo ezihlukahlukene zamaphutha okufakwa kuhlelo lwe-DC.
●Idivayisi ingathola iphuzu lephutha eliphansi ngaphandle kokujova isignali kusistimu ye-DC.Kumodi yesignali, idivayisi inomkhawulo wamanje kanye nemojula yokunciphisa amandla kagesi, engenawo umthelela ohlelweni lwe-DC.
