Izimiso eziyisisekelo zekhabhinethi yesinxephezelo se-high-voltage capacitor: Ezinhlelweni zangempela zamandla, imithwalo eminingi ngamamotho asynchronous.Isifunda sabo esilinganayo singathathwa njengochungechunge lwesekethe yokumelana ne-inductance, umehluko omkhulu wesigaba phakathi kwe-voltage kanye nesici samandla samanje nesiphansi.Lapho ama-capacitor exhunywe ngokufanayo, i-capacitor yamanje izosusa ingxenye yamanje eyenziwe, ngaleyo ndlela inciphise i-current induced, inciphise inani lamanje, inciphise umehluko wesigaba phakathi kwe-voltage kanye ne-current, futhi ithuthukise isici samandla.1. Inqubo yokushintsha iKhabhinethi ye-Capacitor.Lapho ikhabhinethi ye-capacitor ivaliwe, ingxenye yokuqala kufanele ivalwe kuqala, bese ingxenye yesibili;lapho uvala, okuphambene kuyiqiniso.Ukushintsha ukulandelana kwamakhabhinethi e-capacitor yokusebenza.Ukuvala mathupha: vala iswishi yokuhlukanisa → shintsha isilawuli sesibili endaweni yesandla bese uvala iqembu ngalinye lama-capacitor ngalinye ngalinye.Ukuvula okwenziwa ngesandla: shintsha iswishi yokulawula yesibili uye endaweni yesandla, vula iqembu ngalinye lama-capacitor ngalinye → phula iswishi yokuhlukanisa.Ukuvala okuzenzakalelayo: vala inkinobho yokuhlukanisa → shintsha inkinobho yokulawula yesibili endaweni ezenzakalelayo, futhi isinxephezelo samandla sizovala ngokuzenzakalelayo i-capacitor.Qaphela: Uma udinga ukuphuma kukhabhinethi ye-capacitor ngesikhathi sokusebenza, ungacindezela inkinobho yokusetha kabusha kusinxephezelo samandla noma uvule iswishi yokulawula yesibili ibe ziro ukuze uphume ku-capacitor.Ungasebenzisi inkinobho yokuhlukanisa ukuze uphume ngokuqondile ku-capacitor egijima!Lapho ukuguqulwa okuzenzakalelayo noma okuzenzakalelayo, ukunakwa kufanele kukhokhwe ekushintsheni okuphindaphindiwe kwebhange le-capacitor ngesikhathi esifushane.Isikhathi sokulibaziseka sokushintsha akufanele sibe ngaphansi kwamasekhondi angu-30, okungcono kakhulu kunamasekhondi angu-60, ukuze kuvunyelwe isikhathi esanele sokukhipha kuma-capacitor.2. Misa futhi unikeze amandla kukhabhinethi ye-capacitor.Ngaphambi kokunikeza amandla kwikhabhinethi ye-capacitor, i-circuit breaker kufanele ibe sesimweni esivulekile, inkinobho yokukhipha umyalo kuphaneli yokusebenza kufanele ibe sendaweni ethi "Stop", futhi isilawuli sokulawula isinxephezelo samandla kufanele sibe sendaweni ethi "OFF".Kuphela ngemva kokuba isistimu isishajwe ngokugcwele futhi isebenza ngokujwayelekile lapho amandla anganikezwa ikhabhinethi ye-capacitor.Ukusebenza ngesandla kwekhabhinethi ye-capacitor: vala i-circuit breaker yekhabhinethi ye-capacitor, shintsha ukushintshwa komyalo kuphaneli yokusebenza ezindaweni 1 no-2, futhi uxhume ngesandla isinxephezelo sama-capacitor 1 no-2;vula ukushintshwa komyalo endaweni "yokuhlola", futhi ikhabethe le-capacitor lizohlolwa amabhange e-Capacitor.Ukusebenza okuzenzakalelayo kwekhabhinethi ye-capacitor: vala i-circuit breaker yekhabhinethi ye-capacitor, shintsha switch yomyalo kuphaneli yokusebenza uye endaweni "ezenzakalelayo", vala isilawuli sesinxephezelo samandla (ON), bese ushintsha switch yomyalo ku- "run ” isikhundla.” isikhundla.Ikhabethe le-capacitor linxephezela ngokuzenzakalelayo amandla asebenzayo wesistimu ngokuya ngezilungiselelo zesistimu.Isinxephezelo semanuwali singasetshenziswa kuphela lapho isinxephezelo esizenzakalelayo sekhabhinethi ye-capacitor sihluleka.Lapho inkinobho yomyalo kuphaneli yokusebenza yekhabhinethi ye-capacitor ishintshelwa endaweni "yokumisa", ikhabhinethi ye-capacitor iyeka ukusebenza.ezintathu.Ulwazi olwengeziwe mayelana namakhabethe e-capacitor.Kungani ikhabhinethi yesinxephezelo se-capacitor ingenaso isishintshi somoya kodwa ithembele ku-fuse ukuze ivikeleke isifunda esifushane?Amafuse asetshenziselwa ikakhulukazi ukuvikela isifunda esifushane, futhi amafuse asheshayo kufanele akhethwe.Ama-Miniature circuit breaker (MCBs) anejika lesici elihlukile kunamafuse.Umthamo wokuphuka we-MCB uphansi kakhulu (<=6000A).Uma kwenzeka ingozi, isikhathi sokuphendula se-circuit breaker encane asisheshi njengefuse.Uma uhlangabezana nama-harmonics we-oda eliphezulu, i-breaker circuit encane ayikwazi ukuphazamisa amandla wamanje, okungabangela ukuthi ukushintshwa kuqhume futhi konakaliswe.Ngenxa yokuthi iphutha lamanje likhulu kakhulu, othintana nabo be-breaker circuit encane bangase bashiswe, okwenza kungenzeki ukuphuka, ukwandisa ububanzi bephutha.Ezimweni ezimbi kakhulu, kungase kubangele isifunda esifushane noma ukuphela kukagesi kuso sonke isitshalo.Ngakho-ke, i-MCB ayikwazi ukusetshenziswa esikhundleni samafuse emakhabetheni e-capacitor.Isebenza kanjani i-fuse: I-fuse ixhunywe ochungechungeni futhi isekethe ivikelekile.Ngaphansi kwezimo ezijwayelekile, i-fuse ivumela inani elithile lamanje ukuthi lidlule.Uma isifunda sifushane noma silayishwe kakhulu, iphutha elikhulu lamanje ligeleza ku-fuse.Lapho ukushisa okukhiqizwa i-current kufinyelela endaweni yokuncibilika ye-fuse, i-fuse iyancibilika futhi inqamule isifunda, ngaleyo ndlela ifinyelele injongo yokuvikela.Iningi lokuvikela i-capacitor lisebenzisa ama-fuses ukuvikela ama-capacitor, futhi ama-circuit breaker awavamile ukusetshenziswa, cishe awekho.Ukukhethwa kwamafuse ukuze kuvikelwe ama-capacitor: Isilinganiso samanje se-fuse akufanele sibe ngaphansi kwezikhathi ezingu-1.43 zamanje ezilinganiselwe ze-capacitor, futhi akufanele sibe ngaphezu kwezikhathi ezingu-1.55 zamanje ezilinganiselwe ze-capacitor.Hlola ukuze ubone ukuthi i-circuit breaker yakho ingaphansi kosayizi.I-capacitor izokhiqiza amandla athile okuhlinzwa lapho ixhunyiwe noma inqanyuliwe, ngakho-ke i-breaker circuit kanye ne-fuse kufanele kukhethwe ukuthi ibe kukhudlwana kancane.
