Umkhawulo wamanje ovumelekile: I-current evumelekile ayidluli izikhathi ezingu-.3 kunesikhathi esilinganiselwe ukuze sisebenze, futhi i-overcurrent yesikhashana icabangela ukugcwala ngokweqile, ukuchezuka okuhle kwe-capacitor kanye nomthelela wama-harmonics, okungafanele adlule izikhathi ezingu-1.43 kunamanje olinganiselwe.
Ukuhambisana namazinga: Umkhiqizo uhambisana ne-GB/T 11024.1-2009 yamazwe ngamazwe kanye ne-IEC60871-1:2005 yamazwe ngamazwe.
Izici zomkhiqizo kanye nobubanzi bokusetshenziswa
I-capacitor yenziwe ngegobolondo lebhokisi kanye nomgogodla.Igobolondo lebhokisi lenziwe ngepuleti lensimbi elincanyana ngokufakwa uphawu nokushisela.Igobolondo lebhokisi lishiselwe ngomkhono we-porcelain we-outlet.Izinhlangothi ezimbili zodonga lwebhokisi zishiselwe ngama-hangers ukuze zifakwe, futhi uhlangothi olulodwa lwama-hangers lufakwe ama-bolts aphansi.I-capacitor core yakhiwa ngokufaka ama-laminating izingxenye eziningana kanye nezingxenye ezivikelayo, futhi izingxenye zakhiwa ngokugoqa kanye nokwenza isicaba amashidi amabili e-aluminium foil sandwiched paper composite medium noma ifilimu egcwele medium njengamapuleti e-polar.Izingxenye ezisemoyeni zixhunywe ochungechungeni oluthile kanye nemodi ehambisanayo ukuze kuhlangatshezwane nezidingo zama-voltage ahlukene namandla.Ama-Capacitor anamafuse angaphakathi, ingxenye ngayinye inefuse ochungechungeni.Uma ingxenye iphuka, ingxenye engaguquki exhunywe ngokuhambisana nayo izoyikhipha, ukuze i-fuse izoshaywa ngokushesha ngama-milliseconds, futhi ingxenye engalungile izoshaywa umoya.inqanyuliwe, ivumela i-capacitor ukuthi iqhubeke nokusebenza.Ama-capacitor ezigaba ezintathu axhumeke ngenkanyezi.I-liquid medium ku-capacitor isetshenziselwa ukufaka i-medium eqinile futhi igcwalise ama-voids ngaphakathi kwe-capacitor.Inezici ezinhle kakhulu zikagesi nezomzimba futhi inokuhambisana okuhle nezinye izinto ku-capacitor.
Izimo zokusebenza:
Ukuphakama akudluli ku-1000m, izinga lokushisa le-ambient lingu-40/B, kanti izinga lokushisa eliphezulu le-Class B lingu-+45℃.Indawo yokufaka ayinakho ukudlidliza komshini okunzima, ayinawo igesi eyingozi nesitimu, ayinakho uthuli oluqhumayo noma oluqhumayo.Ama-Capacitor kufanele aqinisekiswe ukuthi asebenza ngaphansi kwezimo ezinhle zokungenisa umoya, futhi awavunyelwe ukusebenza ngaphansi kwezimo ezivaliwe nezingenawo umoya.Izintambo zama-capacitor kufanele zibe ama-conductor aguquguqukayo, futhi yonke isifunda kufanele ixhumane kahle.
Ulwazi loku-oda
Ukukhethwa kwe-voltage elinganiselwe ye-capacitor kumele kusekelwe ku-voltage yenethiwekhi.Uma kucatshangelwa ukuthi okokufaka kwe-capacitor kuzokwandisa i-voltage, ngakho-ke lapho ukhetha i-voltage elinganisiwe ye-capacitor, okungenani i-5% ephakeme kune-voltage yenethiwekhi;uma kukhona i-reactor kusekethe ye-capacitor, i-terminal voltage ye-capacitor Umhlabathi ukhuphuka ngezinga lokusabela kwe-reactor ochungechungeni, ngakho-ke lapho kukhethwa i-voltage elinganiselwe ye-capacitor, kufanele inqunywe ngemva kokubala ngokwezinga lokusabela. we-reactor ochungechungeni.Ama-Capacitor angamashaneli aphansi we-harmonics.Ngaphansi kwama-harmonics, inani elikhulu lama-harmonics lizofakwa kuma-capacitor ukwenza ama-capacitor abe ngaphezulu noma ngaphezulu.Ngaphezu kwalokho, ama-capacitor azokhulisa ama-harmonics futhi abangele i-resonance lapho ephelelwa yisikhathi, ebeka engozini ukuphepha kwegridi yamandla futhi enze isikhathi sokuphila se-capacitor.Ngakho-ke, ama-capacitor anama-harmonics amakhulu kufanele asetshenziswe ngaphansi kwama-reactors acindezela ama-harmonics.I-inrush current lapho i-capacitor ivaliwe ingaba phezulu njengezikhathi ezingamakhulu zamanje ezilinganiselwe ze-capacitor.Ngakho-ke, inkinobho yokushintsha i-capacitor kufanele ikhethe ukushintshwa ngaphandle kokuhlukana kabusha.Ukuze ucindezelwe i-inrush current evalayo, i-reactor ecindezela i-inrush current ingaxhunywa ochungechungeni.Ngemva kokuba i-capacitor enokumelana nokukhishwa kwangaphakathi inqanyuliwe kumandla kagesi, ingehla ukusuka enanini eliphakeme le-voltage elinganiselwe iye ngaphansi kuka-75V phakathi nemizuzu eyi-10.kuchazwe nini.Ama-Capacitor asetshenziselwa isinxephezelo solayini kufanele afakwe ku-150 ~ 200kvar endaweni eyodwa, futhi qaphela ukuthi ungafaki ama-capacitor esiteji esifanayo ne-transformer, futhi ungasebenzisi iqembu elifanayo labayeka ukuphuma ukuvimbela ukudubuleka okubangelwa i-ferromagnetic resonance lapho umugqa awusebenzi kuzo zonke izigaba.I-overvoltage yamanje ingalimaza ama-capacitor nama-transformer.I-zinc oxide surge arrester yokuvikela ukuguquguquka kokusebenza kufanele kukhethwe i-zinc oxide surge arrester enikezelwe ku-capacitor, futhi kungcono kakhulu ukuyifaka phakathi kwezigxobo ze-capacitor.I-fuse esetshenziselwa ngokukhethekile i-capacitor ikhethelwa ukuphumula okusheshayo, futhi okwamanje okulinganiselwe kufanele kukhethwe ngokuvumelana nezikhathi ezingu-1.42 ~ 1.5 zamanje ezilinganiselwe ze-capacitor.Lapho i-capacitor ixhunywe ngokuqondile enjini yamandla kagesi aphezulu ngokuhambisana, ukuze kuvinjelwe ukuzikhukhumeza lapho injini inqanyulwa kumandla kagesi, okubangela ukuthi i-voltage yetheminali ye-capacitor inyuke ibe ngaphezu kwenani elilinganiselwe, lamanje elilinganiselwe. i-capacitor kufanele ibe ngaphansi kuka-90% we-no-load current ye-motor;Uma usebenzisa i-Y/△ wiring, ayivunyelwe ukuxhuma i-capacitor ngqo ku-motor ngokuhambisana, futhi indlela yocingo ekhethekile kufanele yamukelwe.Lapho i-capacitor isetshenziswa endaweni ephakeme ngaphezu kwamamitha ayi-1000 noma i-capacitor isetshenziswa endaweni enomswakama oshisayo, kufanele kushiwo lapho uyala.Izitifiketi ezikhethekile ze-spe noma izidingo ezikhethekile zama-capacitor kufanele zicaciswe lapho u-oda.
