Incazelo Yomkhiqizo

Lolu hlobo lwekhoyili yokukhipha lusetshenziswa ohlelweni lwamandla lwe-6-10KV AC 50Hz, ngokuhambisana nebhange le-capacitor yamandla, futhi lusetshenziselwa ukukhipha lapho ugesi unqanyulwa ukuze kuqinisekiswe ukuphepha kwezinto zokusebenza kanye nokuphepha kwabasebenzi bokulungisa.
Lolu hlobo lwekhoyili yokukhipha lunomzimba ethangini likaphethiloli.Umnyombo wensimbi womzimba uwuhlobo lwensimbi lwangaphandle, olupakishwe ngamashidi ensimbi ye-silicon.Amakhoyili okuqala kanye nawesibili afakwa esiqwini ukuze kulinganiswe umugqa noma ukuvikela.Kunezihlahla ezimbili ezinengcindezi ephezulu kanye nezihlahla ezine ezinengcindezi ephansi kukhava yethangi.Umzimba ugxilile kukhava yebhokisi, futhi isembozo sebhokisi sinikezwa i-valve yokukhulula umoya, sonke isakhiwo sihlangene futhi ukuvala kuhle.

Izici zomkhiqizo kanye nobubanzi bokusetshenziswa

1. Lolu hlobo lwekhoyili yokukhipha luthatha isakhiwo esime mpo esivalwe ngokugcwele esisebenza ngokuthembekile.Yamukela ukomiswa kwe-vacuum okugcwele kanye nomjovo kawoyela ukuze kuqinisekiswe ukuthi uwoyela ovikelayo uhlukaniswe ngokuphelele nomoya wangaphandle.Indlela yesinxephezelo sikawoyela we-insulating isebenzisa ubuchwepheshe besinxephezelo esinelungelo lobunikazi obuyingqayizivele.Ngesikhathi sokusebenza kwekhoyili yokukhipha amanzi unyaka wonke, ibhokisi lihlala ligcina ukucindezela okuncane okuhle (okuphakeme kakhulu akukho ngaphezu kuka-0.05Mpa, futhi okungenani akukho ngaphansi kuka-0.001Mpa)
2. Zonke izingxenye zinokusebenza okuhle kokuvala.Akukho kugcinwa noma ukushintshwa kwezingxenye okudingekile ngesikhathi sempilo elindelekile, futhi inomsebenzi wokuvikela ukuqhuma, okuwumkhiqizo ongalungiseki.
3. Imingcele yokuklama inephuzu eliphezulu lokuqala kanye nezinga eliphezulu lokunemba.Izinga lokunemba liqinisekisiwe izikhathi ezingu-0.9-1.3 i-voltage elinganisiwe kanye no-0-50VA olinganiselwe umthwalo wesibili (cos ngu-0.8 lag).Sonke isakhiwo sinengqondo, ukusebenza kuhle kakhulu, umthamo uncane, futhi umumo muhle.
4. Ibhange le-capacitor elihambisanayo lihlanganisa ububanzi obubanzi, okwenza kube lula ukukhethwa nokusebenza okuhambisanayo kwangaphambilini.

Izimo zokusebenza:

1. Izinga lokushisa le-ambient lingu-+40 ° C no-40 ° C, umswakama ohlobene ngu-85%, ukuphakama akudluli amamitha angu-1000, futhi ifakwe ngaphandle.
2. Indawo yokufaka kufanele ingabi nagesi egqwalayo, isitimu, amadiphozithi amakhemikhali, uthuli, ukungcola nezindawo ezingenawo ukudlidliza okuqinile.
3. Igobolondo lekhoyili yokukhipha kufanele lehliswe ngokuthembekile.

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.
