FFM 4.62/6.9/11√3/35√3KV 0.1-25kvar I-Capacitor yaMandla yoKhuselo loMbane oPhezulu
Ingcaciso yeMveliso
I-capacitor ekhuselayo idibaniswe ngokuhambelana ne-vacuum switch.Xa umtshini we-vacuum uqhagamshelwe kumthwalo we-inductive, awukwazi kuphela ukukhawulela ukugqithiswa kokusebenza kuluhlu oluthile, kodwa kunye nokulibazisa ixesha lokunyuka kwe-overvoltage enqunyiwe kunye nokuvutha kwakhona kwentloko ye-wave overvoltage kunye nokunciphisa ukuthambeka, ngaloo ndlela. Ukukhusela isixhobo sombane sigqunyiwe kwimpembelelo yomnqantsa ongaphambili.
Isetyenziswa kwi-50Hz, 3kV, 6kV, 10kV, 35kV iinkqubo zamandla ukwenza i-resistance-capacitance absorber kunye ne-resistor.Isebenzisa amandla afunxwa yi-capacitor ukunciphisa i-voltage amplitude kunye nesiphumo sokudambisa isichasi ukuthoba i-oscillation kunye nokuthintela ukugqithisa.Imowudi yokumisa indawo engathathi hlangothi inqunyelwe ukuqinisekisa ukuba ihambelana nenqanaba le-insulation ye-motor kwaye iphucula umgangatho wokunikezelwa kwamandla wegridi yamandla.
Kwezinye iimeko, inokusetyenziswa kwakhona njenge-capacitor ephezulu-voltage.Xa idityaniswe phakathi kwemigca kunye nomhlaba, inokunciphisa i-atmospheric overvoltage, umnqantsa we-wavefront kunye nexabiso le-peak-to-peak.
Inokukhusela izixhobo zombane xa zisetyenziswa nesibambisi;yicapacitor ehambelanayo ye-RC overvoltage absorption device ye-vacuum circuit breaker system.
Inkcazo yoMfanekiso
Iiparamitha zobugcisa kunye nemilinganiselo yesakhiwo
■ Ukusebenza kobugcisa

B. Ngefilim epheleleyo: tanδ≤0.0005.
● Ireyithiwe rhoqo: fn=50Hz.
● I-capacitor inokusebenza ixesha elide phantsi kwe-1.1Un, kwaye inokumelana nokugqithisa kokusebenza okubangelwa ukuvulwa kunye nokuvalwa kwe-circuit breaker kunye nexabiso lokuqala le-peak ≤2.5 2Un.
● I-capacitor inokuhamba ixesha elide phantsi kwe-1.5In, le yangoku iquka i-current ebangelwa ukutshatyalaliswa kwe-steady-state overvoltage, iphinda ibandakanye i-current ebangelwa yi-harmonics, kwaye iquka ukunyuswa kwangoku ngokuphambuka kwe-capacitance.
● Indlela yokupholisa: i-convection yendalo yomoya kumphezulu we-capacitor shell.
● Umphakamo wofakelo kunye nendawo yokusebenza akuyi kuba ngaphezu kwe-1000m;iqondo lobushushu bomoya okwindawo yofakelo kunye nendawo yokusebenza: ngaphakathi -40~+45℃;ukufuma kwesihlobo somoya ≤95%.
●Ufakelo kunye nendawo yokusebenza kufuneka ingabinarhasi enomhlwa kunye nomphunga;akukho luthuli oluqhumayo okanye oluqhumayo kunye nokungcangcazela okuqatha koomatshini.
● Akufuneki kubekho uthuli oluninzi kunye nokungcola kumphezulu we-ceramic sleeve ye-capacitor.Ukuba kufunyenwe ukuvuza kwe-oyile, umsebenzi kufuneka umiswe.
Iimpawu zemveliso kunye nobungakanani bokusetyenziswa
I-capacitor iqulunqwe ikakhulu yigobolondo kunye nengundoqo.Iqokobhe lidityaniswe ngepleyiti yentsimbi ecekethekileyo, isigqubuthelo siqulethe umkhono weporcelain wocingo, kwaye amacala omabini eludongeni adityaniswe ngeepleyiti zeAngle zokufakelwa.Ingundoqo ihlanganiswe ngokupheleleyo yinxalenye, inxalenye ye-insulating kunye ne-hoop eqinile, kwaye i-medium component ihlanganiswe nge-electrode ehlukaniswe yiyo.
Izinto zokukhusela ezikumgangatho ophezulu kunye neziphezulu zikhethwa njengemithombo yeendaba eqinileyo, kwaye inkqubo ekhethekileyo yokukhupha i-vacuum evaporation isetyenziselwa ukukhupha isinyithi ukwenza isakhiwo esithile semoto.Yenziwe iyunithi ye-capacitor kumatshini ozenzekelayo, kwaye emva koko yenziwe i-capacitor ngeteknoloji enelungelo elilodwa lomenzi, kwaye isetyenziswe kwi-series kunye ne-resistor ekhethekileyo engekho inductive.
Iimeko zokusebenza:
1. Uluhlu lobushushu bomoya okwi-Ambient: -40~+45℃, ukufuma kungabikho ngaphezulu kwe-95%.
2. Akukho rhasi edliwayo kunye nomphunga kwindawo yofakelo, akukho luthuli oluqhumayo okanye oluqhumayo kunye nokungcangcazela komatshini.
3. Indlela yokufakela: ukufakwa ngokuthe nkqo.
Ukuodola ulwazi
Ukukhethwa kombane olinganisiweyo we-capacitor kufuneka kusekelwe kumbane womnatha.Ukuqwalasela ukuba igalelo le-capacitor liya kwandisa i-voltage, ngoko xa ukhetha i-voltage elinganisiweyo ye-capacitor, ubuncinane i-5% ephezulu kune-network network;xa kukho i-reactor kwisekethe ye-capacitor, i-terminal voltage ye-capacitor Umhlaba uyanda kunye nesantya sokusabela kwe-reactor kuchungechunge, ngoko ke xa ukhetha i-voltage elinganisiweyo ye-capacitor, kufuneka imiselwe emva kokubala ngokwezinga lokuphendula. yereactor kumtya.I-Capacitors i-low-impedance channels of harmonics.Ngaphantsi kwe-harmonics, inani elikhulu le-harmonics liya kujovwa kwi-capacitors ukwenza i-capacitors overcurrent okanye overvoltage.Ukongezelela, i-capacitors iya kukhulisa i-harmonics kwaye ibangele i-resonance xa iphelile, ibeka engozini ukhuseleko lwegridi yamandla kunye nokwenza ubomi be-capacitors.Ngoko ke, ii-capacitors ezine-harmonics ezinkulu kufuneka zisetyenziswe phantsi kwee-reactors ezicinezela i-harmonics.I-inrush yangoku xa i-capacitor ivaliwe ingaba phezulu ngamakhulu amaxesha okulinganiswa kwangoku kwe-capacitor.Ngoko ke, utshintsho lokutshintsha i-capacitor kufuneka lukhethe ukutshintsha ngaphandle kokuphinda kuhlaziywe.Ukuze ucinezele i-inrush yangoku yokuvala, i-reactor ecinezela i-inrush current inokudityaniswa kuthotho.Emva kokuba i-capacitor enokumelana nokukhutshwa kwangaphakathi inqanyuliwe kunikezelo lwamandla, inokuhla ukusuka kwixabiso eliphezulu lombane olinganisiweyo ukuya ngaphantsi kwe-75V kwimizuzu eyi-10.kucaciswa nini.Iicapacitors ezisetyenziselwa imbuyekezo yomgca kufuneka zifakwe kwi-150 ~ 200kvar kwindawo enye, kwaye ulumke ungafaki i-capacitors kwinqanaba elifanayo ne-transformer, kwaye ungasebenzisi iqela elifanayo labayekayo ukunqanda ukudubula okubangelwa yi-ferromagnetic resonance xa umgca awusebenzi kuzo zonke izigaba.Ukugqithisa kwangoku kungonakalisa i-capacitors kunye ne-transformers.I-zinc oxide surge arrester yokukhusela i-overvoltage yokusebenza kufuneka ikhethwe kwi-zinc oxide surge arrester enikezelwe kwi-capacitor, kwaye kukulungele ukuyifaka phakathi kweepali ze-capacitor.I-fuse esetyenziselwa ngokukhethekileyo i-capacitor ikhethwa ngokukhawuleza-ikhefu, kwaye i-current rated current kufuneka ikhethwe ngokwe-1.42 ~ 1.5 amaxesha okulinganiswa kwangoku kwe-capacitor.Xa i-capacitor iqhagamshelwe ngokuthe ngqo kwi-motor-voltage ephezulu ngokuhambelanayo, ukuze kuthintelwe ukuzivuselela xa i-motor ivaliwe kunikezelo lwamandla, okubangela ukuba i-voltage ye-terminal ye-capacitor iphakame ngaphezu kwexabiso elilinganisiweyo, i-current rated current. ye-capacitor kufuneka ibe ngaphantsi kwe-90% ye-no-load current ye-motor;Xa usebenzisa i-Y / △ i-wiring, ayivumelekanga ukudibanisa i-capacitor ngqo kwi-motor ngokuhambelana, kwaye indlela ekhethekileyo yocingo kufuneka yamkelwe.Xa i-capacitor isetyenziswe kwindawo ephakamileyo ngaphezu kweemitha ezili-1000 okanye i-capacitor isetyenziswe kwindawo eshushu yetropiki, kufuneka ichazwe xa iyala.Izatifikethi ezikhethekileyo ze-spe okanye iimfuno ezikhethekileyo ze-capacitors kufuneka zichazwe xa ziyala.
