I-Online Monitoring System ye-Metal Oxide Arrester
Ngokuvamile kunezindlela ezimbili zokuqapha isimo sokufakelwa kwamandla kagesi aphezulu eziteshini ezincane: ukuqapha ku-inthanethi kanye nokutholwa okubukhoma (okuphathekayo) ku-inthanethi.Owokuqala angathola amapharamitha wesici abonisa ukufakwa okungavamile kwemishini nganoma yisiphi isikhathi, okulungele ukuphathwa okuzenzakalelayo.Nokho, ukutshalwa kwezimali kukhulu uma kuqhathaniswa, ukufakwa nokwakhiwa kunezinkinga uma kuqhathaniswa, futhi ukunakekelwa okuvamile kuyadingeka.Okokugcina, inezinzuzo zokutshalwa kwezimali okuphansi, okuqondiswe kakhulu, kulula ukukufaka, ukunakekela nokuvuselela.Inqobo nje uma iyunithi yokusampula ifakiwe emshinini kagesi kusenesikhathi, ukubonwa okuvamile kungenziwa emishinini kagesi esebenzayo, futhi iphutha lokuhlukanisa lingatholakala ngesikhathi, ukuze kwelule isikhathi sokuqala sokuhluleka kwamandla futhi kufakwe esikhundleni ngokuphelele. -line indlela yokuqapha.
Umhloli wokulahlekelwa kwe-dielectric we-GDDJ-HVC wemishini ye-capacitive ephilayo ingasetshenziswa ukukala ukulahleka kwe-dielectric kanye namandla emishini ye-capacitive (i-bushing, i-CT, i-CVT, i-coupling capacitor), kanye nokubona amaphutha okufakwa kwe-insulation ngempumelelo.
1. Inzwa yamanje yohlobo lwembobo yangaphandle enembayo ephezulu ivame ukusetshenziswa esikhundleni seyunithi yesampula evamile, ehlanganisa isekethe yokushintsha engaphezu kweyodwa.Ngesikhathi sokuhlola, amathebhu amaningi amafushane ayadingeka ukuze kuhole isivikelo sokuphela ukuze sihlole ithuluzi.I-GDDJ - I-HVC isebenzisa isakhiwo sendabuko esiqondile, singafakwa eduze kwemishini, ukuhola kokuvikela ukuphela akuphukile futhi ubude bufushane kakhulu, okugwema ukujikeleza okuvulekile kokuvikela ukuphela.Inzwa ingakwazi ukubona ngokunembile amasiginali phakathi kuka-100μA~700mA.I-impedance of sensor iphansi, ingamelana ne-power frequency current 10A kanye no-10kA impulse yombani yamanje, ihlangabezane nezimo zokusebenzisa zokutholwa ku-inthanethi.
2. Iyunithi yesampula isebenzisa i-die-casting aluminium igobolondo elivala amanzi, futhi yamukela isixhumi sekhebula elingangeni manzi ukuze sikhiphe okwesibili, esilungele ukuxhunywa;Ngemva kokufakwa kwenzwa, ngokuvamile ayinikwa amandla.Ukuze kuhlolwe, ikhebula yesibili kuphela yeyunithi yesampula edinga ukuxhunywa, futhi "ipulaki ne-play" ingafinyelelwa ngaphandle kwanoma yikuphi ukusebenza kukhebula yesiginali evikela isiphetho.
3. Iphrosesa eyinhloko yensimbi i-American TI 32-bit floating-point high performance digital signal processor (DSP), esebenzisa isistimu yokusebenza yesikhathi sangempela futhi yamukela ukuvumelanisa kwe-16-bit, isivinini esikhulu, neziteshi eziningi. isampula ye-analog digital converter (A/D) ukuze uthole ukulinganisa kwesikhathi sangempela nokubala okunembayo okuphezulu kwenani eligadiwe.Iyakwazi ukuqapha amadivaysi amaningi ngesikhathi esisodwa.
4. Izindlela ezimbili zokutholwa kwe-inthanethi zokulahlekelwa kwe-dielectric zinganikezwa, ezingalinganisa umehluko wokulahlekelwa kwe-dielectric kanye nesilinganiso se-capacitance yamadivayisi amabili e-capacitive esigabeni esifanayo, futhi i-PT yesibili voltage ingasetshenziswa njengesignali yereferensi ukukala i-capacitance ne-dielectric. ukulahlekelwa idivayisi.Ngokusebenzisa inzwa yamanje enxephezela kanye nobuchwepheshe obuthuthukisiwe bokuhlunga kwedijithali, inkinga yokunemba kokulahlekelwa kwe-dielectric nokuzinza iyaxazululwa, kuhlanganiswe nezinyathelo eziphelele zokuvikela i-electromagnetic kanye nobuchwepheshe obuthuthukisiwe bokucutshungulwa, ukuhlunga kwedijithali kungaqinisekisa ukuthi imiphumela yokuhlolwa kokulahlekelwa kwe-dielectric ayithinteki ithonya lokuphazanyiswa kwe-harmonic. kanye nokuphazamiseka kokushaya kwenhliziyo, ngokunemba okuphelele kufika ku-±0.05%.
5. Ngokutholwa komehluko wokulahlekelwa kwe-dielectric kanye nesilinganiso se-capacitance ye-in-phase capacitive imishini, ayikwazi nje ukugwema ukuhlanekezela umphumela wokuhlolwa kokulahlekelwa kwe-dielectric okubangelwa ukusebenzisa i-PT voltage yesibili njengesignali yereferensi, kodwa futhi kusiza ukunciphisa ithonya ukuphazamiseka kwensimu kagesi yesigaba nesigaba.
6. Umtshina ufakwe isikrini esikhulu se-LCD sokubonisa i-voltage egadiwe, yamanje, i-dielectric loss, resistive current, capacitive current kanye neminye idatha.
7. Umhloli akagcini nje ngokuba nomsebenzi wokutholwa bukhoma, kodwa futhi angakwazi ukuqapha okokusebenza ku-inthanethi isikhathi eside, futhi aqophe ngokuzenzakalelayo idatha egadiwe.
8. Uhlelo lwamukela izinzwa zangaphandle esikhundleni se-"traditional sampling unit", engathuthukiswa kalula isuke "kukuthola bukhoma" kuya "kukuqapha ku-inthanethi" ngaphansi kokusebenza okuvamile kwemishini.Asikho isidingo sokususa izinzwa ezifakiwe, asikho isidingo sokukhubaza idivayisi, vele wengeze iyunithi yokuqapha (IED).
9. Umtshina wamukela ukuklama okuphathekayo, okulula ukusebenza, ibhethri ye-lithium emshinini ingagcina amahora angu-8 esikhathi esiqhubekayo sokusebenza, ukuhlangabezana ngokugcwele nezidingo zokusetshenziswa kwensimu.
