Incazelo Yomkhiqizo

I-capacitor evikelayo ixhunywe ngokuhambisana ne-vacuum switch.Uma iswishi ye-vacuum ixhunywe kumthwalo we-inductive, ayikwazi nje kuphela ukukhawulela i-overvoltage yokusebenza ebangeni elithile, kodwa futhi ibambezele isikhathi sokukhuphuka kwe-overvoltage enqunyiwe kanye nekhanda le-wave overvoltage elivutha kabusha futhi linciphise ukukhuphuka, ngaleyo ndlela. ukuvikela Impahla kagesi ivalekile emthelela wegagasi eliwumqansa ngaphambili.
Isetshenziswa kumasistimu wamandla angu-50Hz, 3kV, 6kV, 10kV, 35kV ukuze kwakheke isibambi esinamandla okumelana nesimelaphi.Isebenzisa amandla amuncwa i-capacitor ukunciphisa i-voltage amplitude kanye nomphumela odambisayo we-resistor ukunciphisa i-oscillation nokuvimbela ukugcwala ngokweqile.Imodi yokubeka phansi yephoyinti elingathathi hlangothi ikhawulelwe ukuze kuqinisekiswe ukuthi ifana nezinga lokufakwa kwenjini futhi ithuthukisa ikhwalithi yokunikezwa kwamandla wegridi yamandla.
Kwezinye izimo, ingasetshenziswa futhi njenge-high-voltage capacitor.Uma ixhunywe phakathi kwemigqa nomhlabathi, inganciphisa ukugcwala komkhathi, ukukhuphuka kwamagagasi ngaphambili kanye nevelu yokufika phezulu.
Ingakwazi ukuvikela izinto zikagesi uma zisetshenziswa nesibambisi;iyi-capacitor ehambisanayo yedivayisi yokumunca i-RC overvoltage yesistimu ye-vacuum circuit breaker.

● Imvamisa elinganiselwe: fn=50Hz.
●I-capacitor ingasebenza isikhathi eside ngaphansi kwe-1.1Un, futhi ingamelana no-overvoltage wokusebenza okubangelwa ukuvulwa nokuvalwa kwe-circuit breaker enenani eliphakeme lokuqala elingu-≤2.5 2Un.
●I-capacitor ingasebenza isikhathi eside ngaphansi kwe-1.5In, lokhu kwamanje kufaka phakathi okwamanje okubangelwa ukugcwala kwe-voltage engashintshi, futhi kufaka phakathi okwamanje okubangelwa ama-harmonics, futhi kufaka phakathi okwamanje okukhuliswe ukuchezuka kwe-capacitance.
● Indlela yokupholisa: ukuhanjiswa komoya okungokwemvelo phezu kwegobolondo le-capacitor.
●Ukuphakama kwendawo yokufaka nokusebenza akumele kudlule ku-1000m;izinga lokushisa lomoya elizungezile lendawo yokufaka nokusebenza: ngaphakathi -40～+45℃;umswakama ohlobene nomoya ≤95%.
●Indawo yokufaka nendawo yokusebenza kufanele ingabi nayo igesi egqwalayo nesitimu;alukho uthuli oluqhumayo noma oluqhumayo kanye nokudlidliza komshini okunzima.
● Akufanele kube nothuli oluningi nokungcola ebusweni bomkhono we-ceramic we-capacitor.Uma ukuvuza kukawoyela kutholakala, ukusebenza kufanele kumiswe.

Izici zomkhiqizo kanye nobubanzi bokusetshenziswa

I-capacitor yakhiwa ikakhulukazi igobolondo kanye nomgogodla.Igobolondo lishiselwe ipuleti lensimbi elincanyana, isembozo siqukethe umkhono we-porcelain we-wire outlet, futhi izinhlangothi zombili zodonga zishiselwe ngama-Angle plate ukuze afakwe.I-core ihlanganiswe ibe yinto yonke nge-component, ingxenye evikelayo kanye ne-hoop eqinile, futhi ingxenye yengxenye ihlanganiswe ne-electrode ehlukaniswe yiyo.
Izinto zokuvikela ezisezingeni eliphezulu nezisebenza kahle kakhulu zikhethwa njengemidiya eqinile, futhi inqubo ekhethekile yokuhwamuka kwe-vacuum ephezulu isetshenziselwa ukuhwamulisa insimbi ukuze kwakhiwe isakhiwo esithile semoto.Yenziwa iyunithi ye-capacitor emshinini wokugoqa othomathikhi, bese yenziwa i-capacitor enobuchwepheshe obunelungelo lobunikazi, bese isetshenziswa ochungechungeni olunomphikisi okhethekile ongenayo inductive.

Izimo zokusebenza:

1. Ibanga lokushisa lomoya elizungezile: -40～+45℃, umswakama ohlobene awukho ngaphezu kuka-95%.
2. Ayikho igesi egqwalayo nesitimu endaweni yokufaka, alukho uthuli oluqhumayo noma oluqhumayo kanye nokudlidliza kwemishini okunzima.
3. Indlela yokufaka: ukufakwa okuqondile.

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.
