Ukukhishwa Kwengxenye Yesistimu Yokuqapha Ku-inthanethi Yamajeneretha
Ngokuvamile, ukukhishwa okuyingxenye kwenzeka endaweni lapho izakhiwo ze-dielectric material zingafani.Kulezi zindawo, amandla wendawo kagesi ayathuthukiswa, futhi amandla wendawo kagesi makhulu kakhulu, okuholela ekulimazeni kwendawo.Lokhu kuhlukana ngokwengxenye akukhona ukuwohloka okuphelele kwesakhiwo se-insulating.Ukukhishwa okuyingxenye ngokuvamile kudinga inani elithile lesikhala segesi ukuze kuthuthuke, njengama-gas voids ngaphakathi kwe-insulation, ama-conductor aseduze, noma i-interfaces ye-insulating.
Lapho amandla ensimu yendawo edlula amandla e-dielectric wento efaka i-insulating, ukukhishwa okuyingxenye kwenzeka, okubangela ama-pulses amaningi okukhipha ingxenye ukuba enzeke phakathi nomjikelezo owodwa wokusebenzisa i-voltage.
Inani lokukhishwa okulethiwe lihlobene eduze nezici ezingezona ezilinganayo kanye nezici ezithile ze-dielectric zezinto.
Ukukhishwa okuphawulekayo okuyingxenye emotweni ngokuvamile kuwuphawu lwezinkinga zokufakelwa, njengekhwalithi yokukhiqiza noma ukuwohloka kwangemva kokugijima, kodwa lokhu akusona isizathu esiqondile sokwehluleka.Kodwa-ke, ukukhishwa okuyingxenye emotweni kungalimaza ngokuqondile ukufakwa futhi kuthinte inqubo yokuguga.
Izilinganiso ezithile zokukhishwa kokukhishwa okuyingxenye kanye nokuhlaziya kungasetshenziswa ngempumelelo ekulawuleni ikhwalithi yamawindi amasha kanye nezingxenye ezisongayo kanye nokutholwa kusenesikhathi kokulimala kokufakwa kwe-insulation okubangelwa izici ezifana nezingcindezi ezishisayo, zikagesi, zemvelo kanye nemishini ekusebenzeni, okungaholela ekuhlulekeni kokufakwa kwezinto.
Ngenxa yamasu athile okukhiqiza, amaphutha okukhiqiza, ukuguga okujwayelekile noma ukuguga okungavamile, ukukhishwa okuyingxenye kungase kuthinte ukwakheka kokufakwa kwe-stator kuwo wonke ama-winding.Idizayini yemoto, izici zezinto ezifaka i-insulating, izindlela zokukhiqiza, nezimo zokusebenza zithinta kakhulu inombolo, indawo, imvelo, kanye nokuthuthuka komkhuba wokukhipha ingxenye.Ezimweni eziningi, ngokusebenzisa izici zokukhishwa okuyingxenye, imithombo ehlukene yokukhishwa kwendawo ingabonakala futhi ihlukaniswe.Ngokusebenzisa ithrendi yentuthuko kanye nemingcele ehlobene, ukwahlulela isimo sokufakwa kwesistimu, nokuhlinzeka ngesisekelo sangaphambili sokunakekela.
Ipharamitha yezinhlamvu zokukhipha ingxenye
1. Inkokhelo esobala yokukhipha q(pc).qa=Cb/(Cb+Cc), inani lokukhipha ngokuvamile livezwa yinkokhiso ebonakala iphindelela yokukhipha qa.
Kubandakanya i-Cc amandla alingana nephutha
2. Isigaba sokukhipha φ (amadigri)
3. Izinga lokuphindaphinda kokukhishwa
Inkundla yesoftware
Umqoqi we-PD
Inzwa yokukhipha ingxenye engu-6pcs
Ikhabhinethi yokulawula (ukubeka ikhompuyutha yezimboni nokuqapha, iphakamisa ukuthi ihlinzekwe ngumthengi)
1. Inzwa yesiginali yokukhipha ingxenye
Inzwa yokukhishwa kwengxenye ye-HFCT iqukethe ingqikithi kazibuthe, ikhoyili ye-Rogowski, iyunithi yokuhlunga nesampula, kanye nebhokisi lokuvikela i-electromagnetic.Ikhoyili ilinyazwe kumongo kazibuthe onokungena okuphakeme kazibuthe kumafrikhwensi aphezulu;Idizayini yeyunithi yokuhlunga nesampula icabangela izidingo zokuzwela kokulinganisa kanye nebhendi yefrikhwensi yokusabela kwesignali.Ukuze ucindezele ukuphazamiseka, uthuthukise isilinganiso sesignali-kuya-nomsindo, futhi ucabangele izidingo zokuvikela imvula nokuvikela uthuli, amakhoyili e-Rogowski namayunithi okusampula amasampula afakwa ebhokisini lokuvikela lensimbi.Ikesi lesihlangu lakhiwe ngebhande lokuzikhiya elingavulwa ngokucindezela ukuze kwandiswe ukuqinisekisa ukunethezeka kokufakwa kwezinzwa nokuphepha ngesikhathi sokusebenza.Inzwa ye-HFCT isetshenziselwa ukukala ukufakwa kwe-PD kumawinding e-stator.

Ukukhishwa okulinganiselwe okulinganiselwe: 5pC;ibhande lokulinganisa: 500kHz-30MHz;khipha ukulungiswa kwe-pulse: 10μs;ukulungiswa kwesigaba: 0.18°.
Ingabonisa idayagramu yokukhishwa komjikelezo wemvamisa yamandla, i-two-dimensional (Q-φ, N-φ, NQ) kanye ne-spectra yokukhipha i-three-dimensional (NQ-φ).
Ingakwazi ukurekhoda amapharamitha afanelekile njengokulandelana kwesigaba sokulinganisa, inani lokukhipha, isigaba sokukhipha kanye nesikhathi sokulinganisa.Ingahlinzeka ngegrafu yethrendi yokukhipha futhi inesexwayiso sangaphambilini nemisebenzi ye-alamu.Ingakwazi ukubuza, ukususa, ukwenza isipele futhi iphrinte imibiko kusizindalwazi.
Uhlelo luhlanganisa okuqukethwe okulandelayo kokutholwa nokucutshungulwa kwesignali: ukutholwa kwesignali nokudluliselwa, ukukhipha isici sesignali, ukubonwa kwephethini, ukuhlonza iphutha nokuhlola isimo sempahla yekhebula.
Uhlelo lunganikeza ulwazi lwesigaba kanye ne-amplitude yesiginali ye-PD kanye nolwazi lokuminyana kwe-pulse yokukhipha, okuwusizo ukwahlulela uhlobo nobukhulu bokukhishwa.
Ukukhetha imodi yokuxhumana: ikhebuli yenethiwekhi yokusekela, i-fiber optic, i-wifi yokuzihlela i-LAN.
3. Uhlelo lwesoftware ye-PD
Uhlelo lusebenzisa isofthiwe yokumisa njengenkundla yokuthuthukisa yokuthola nokuhlaziya isofthiwe ukuze kuqinisekiswe ukuqaliswa okuhle kobuchwepheshe bokulwa nokuphazamiseka.Isofthiwe yesistimu ingahlukaniswa ngokulungiselelwa kwepharamitha, ukutholwa kwedatha, ukucutshungulwa kokuphazanyiswa, ukuhlaziya i-spectrum, ukuhlaziya izitayela, ukuqoqwa kwedatha nokubika.
Phakathi kwazo, ingxenye yokutholwa kwedatha ngokuyinhloko iqedela ukulungiselelwa kwekhadi lokutholwa kwedatha, njengenkathi yamasampula, indawo ephezulu yomjikelezo, nesikhawu samasampula.Isofthiwe yokutholwa iqoqa idatha ngokuvumelana nemingcele yekhadi lokutholwa elimisiwe, futhi ngokuzenzakalelayo ithumela idatha eqoqiwe kusofthiwe yokulwa nokuphazamiseka ukuze icutshungulwe.Ngaphandle kwengxenye yokucubungula emelene nokuphazamiseka, eyenziwa ngemuva kohlelo, okunye kuboniswa ngesixhumi esibonakalayo.
Izici zesistimu yesoftware
Isixhumi esibonakalayo esiyinhloko sishukumisa ngamandla ulwazi lokuqapha olubalulekile futhi sichofoze ukwaziswa okuhambisanayo ukuze sithole ngokuqondile imininingwane enemininingwane.
I-interface yokusebenza ilungele ukusetshenziswa futhi ithuthukise ukusebenza kahle kokutholwa kolwazi.
Ngomsebenzi wokusesha wesizindalwazi onamandla wombuzo wefomu, igrafu yethrendi kanye nokuhlaziya isexwayiso sangaphambilini, ukuhlaziya i-spectrum, njll.
Ngomsebenzi wokuqoqwa kwedatha eku-inthanethi, ongaskena idatha yesistimu engaphansi ngayinye esiteshini ngesikhathi esibekwe umsebenzisi.
Ngomsebenzi wokuxwayisa ngephutha lemishini, lapho inani elilinganisiwe lento etholwayo ku-inthanethi lidlula umkhawulo we-alamu, isistimu izothumela umlayezo we-alamu ukukhumbuza opharetha ukuthi asingathe okokusebenza ngokufanele.
Uhlelo lunomsebenzi ophelele wokusebenza nokunakekela, ongagcina idatha yesistimu kalula, imingcele yesistimu, namalogi okusebenza.
Uhlelo lunokukala okuqinile, olukwazi ukubona kalula ukwengezwa kwezinto ezitholwayo zombuso zamadivayisi ahlukahlukene, futhi livumelane nokwandiswa kwevolumu yebhizinisi nezinqubo zebhizinisi;Ngomsebenzi wokuphathwa kwelogi, orekhoda izingodo zokusebenza komsebenzisi kanye namalogi okuphatha ukuxhumana kwesistimu ngokuningiliziwe, ongabuzwa kalula noma uzinakekele.
4. Ikhabhinethi yokulawula
Ikhabethe lokulawula libeka imonitha kanye nekhompyutha yezimboni, noma ezinye izesekeli ezidingekayo.Kungcono ukunikezwa ngokusetshenziswa
Ikhabhinethi ifakwe ngokuqinile egumbini lokulawula eliyinhloko lesiteshi, futhi ezinye izindawo zingakhethwa ukuze zifakwe ngokuvumelana nezidingo zesayithi.
1. Imisebenzi
Inzwa ye-HFCT isetshenziselwa ukukala ukufakwa kwe-PD kumawinding e-stator.I-epoxy mica HV coupling capacitor ingu-80pF.Ama-coupling capacitor okulinganisa kufanele abe nokuzinza okuphezulu kanye nokuzinza kwe-insulation, ikakhulukazi i-pulse overvoltage.Izinzwa ze-PD nezinye izinzwa zingaxhunywa kumqoqi we-PD.I-Wideband HFCT isetshenziselwa ukucindezela umsindo.Ngokuvamile, lezi zinzwa zifakwe kukhebula lamandla eliphansi.
Isici esinzima kakhulu sesilinganiso se-PD ukucindezela umsindo emishinini yamandla kagesi aphezulu, ikakhulukazi ukulinganisa kwe-HF pulse ngoba kunomsindo omkhulu.Indlela ephumelela kakhulu yokucindezela umsindo yindlela "yesikhathi sokufika", esekelwe ekutholeni nasekuhlaziyeni umehluko ezikhathini zokufika kokushaya kwezinzwa eziningana ukusuka ku-PD eyodwa ukuya ohlelweni lokuqapha.Inzwa izobekwa eduze nendawo yokukhishwa kwe-insulated lapho ama-pulses asekuqaleni okuvama kokuphuma kukalwa.Ukuma kwesici se-insulation kungatholwa umehluko wesikhathi sokufika kwe-pulse.
