Ukuodola ulwazi kunye nemicimbi yoFakelo

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.

Ukufakela kunye nokusetyenziswa imicimbi:
● Ukufakwa kwee-capacitors akuvumelekanga ukuba kubekho i-vibration phenomenon.Kuvunyelwe ukufaka i-capacitors kufuphi ne-heater, kodwa izinto ezingenakutsha kufuneka zisetyenziswe njengeendonga eziqinileyo zokwahlula ukujikeleza i-capacitors okanye zifakwe kwikhabhinethi yentsimbi eyahlukileyo.
● Ukuthintela umbhobho wokupholisa we-capacitor ukuba wonakaliswe, ubushushu bendawo yokufakela i-capacitor akufanele bube ngaphantsi kwe-± 2℃.
●I-capacitor kufuneka ifakwe ngokuthe nkqo (umkhono we-porcelain ujonge phezulu).Kuvinjelwe ngokungqongqo ukusebenzisa i-sleeve ye-porcelain ukuhambisa i-capacitor, kwaye ikhefu phakathi kwe-capacitors ubuncinane i-20 mm.
● Ukudityaniswa phakathi kwemibhobho yamanzi okupholisa ye-capacitor kunye nokudibanisa phakathi kombhobho wamanzi okupholisa kunye nombhobho womthombo wamanzi kufuneka kwenziwe ngemibhobho yerabha ethambileyo.Imibhobho yamanzi yokupholisa inokudibaniswa kwichungechunge, kodwa ingabi ngaphezu kwee-capacitors ezintathu.Umbhobho wokucoca akufanele ugutyungelwe, kwaye kufuneka ubekwe kwindawo apho kulula ukujonga ukuphuma kwamanzi, ukwenzela ukuba ukuphuma kwamanzi kunokujongwa nangaliphi na ixesha.
●Ubushushu bamanzi okupholisa akufunekanga budlule +30℃ kwindawo yokungena kunye ne +35℃ kwindawo yokuphuma.
Xa inani elithile lemibhobho yamanzi okupholisa idityaniswe kwichungechunge (ukuya kwiiseti ezi-3), uxinzelelo lwamanzi kunye nokusetyenziswa kwamanzi kunokulungelelaniswa ukulungelelanisa umlinganiselo weqondo lokushisa phakathi kokungena kunye nokuphuma kwamanzi, ukwenzela ukuba ukushisa kwindawo yokuphuma kungadluli. + 35 ℃, kunye noxinzelelo lwamanzi okupholisa kwindawo yokungena akufuneki ludlule i-4 yoxinzelelo lwe-atmospheric.
● Ukuba ukunikezelwa kwamanzi kumisiwe ngenxa yesiphoso, ukunikezelwa kombane we-capacitor kufuneka kunqunyulwe ngokukhawuleza.Xa i-capacitor ingasebenzi ngenxa yesiphoso, onke amanzi kumbhobho wamanzi okupholisa kufuneka akhutshwe.
●Xa ii-outlet ezininzi ezidibeneyo kwi-capacitor zisetyenziswa ngokufanayo, kufuneka kusetyenziswe iphepha lokudibanisa eliguquguqukayo.Ngexesha elifanayo, i-outlet ephambili kufuneka ikhutshwe kwi-flexible connection, kwaye ayifanele ikhutshwe kuyo nayiphi na enye yeevenkile ezidibeneyo.Ummandla onqamlezileyo wesiqwenga sokudibanisa awuyi kuba ngaphantsi kwe-2.5cm2.
● Xa i-voltage yomgca iphezulu kune-voltage elinganisiweyo ye-capacitor, inani le-capacitor elixhunyiwe kwi-series liyakwazi ukulungelelaniswa okanye ukukhokela nganye kwi-capacitor edibeneyo kwi-series ingasetyenziselwa uchungechunge.
