Iimpawu zemveliso kunye nobungakanani bokusetyenziswa

I-capacitor yenziwe ngegobolondo lebhokisi kunye nengundoqo.Iqokobhe lebhokisi lenziwe ngepleyiti yentsimbi encinci ngokutywinwa kunye ne-welding.Iqokobhe lebhokisi lidityaniswe ngomkhono weporcelain ophumayo.Amacala amabini odonga lwebhokisi adityaniswe ngee-hangers zofakelo, kwaye elinye icala le-hangers lixhotyiswe ngeebholiti zomhlaba.I-capacitor core yenziwa ngokulayita amacandelo amaninzi kunye neendawo zokugquma, kwaye amacandelo enziwa ngokuqengqeleka kunye nokuthambisa amaphepha amabini efoyile ye-aluminium efakwe iphepha elihlanganisiweyo eliphakathi okanye ifilimu epheleleyo njengeepleyiti zepolar.Amacandelo angundoqo axhunyiwe kuchungechunge oluthile kunye nemodi ehambelanayo ukuhlangabezana neemfuno zombane ohlukeneyo kunye namandla.I-Capacitors ene-fuses yangaphakathi, icandelo ngalinye line-fuse kwi-series.Xa icandelo lidiliza, icandelo elingaguqukiyo elidityaniswe ngokuhambelana nalo liya kuyikhupha, ukwenzela ukuba i-fuse ivuthelwe ngokukhawuleza kwii-milliseconds, kwaye inxalenye ephosakeleyo iya kuphuma.inqunyulwe, ivumela i-capacitor ukuba iqhubeke nokusebenza.Ii-capacitors zesigaba sesithathu zixhunyiwe inkwenkwezi.I-liquid medium in the capacitor isetyenziselwa ukufaka i-medium eqinile kwaye igcwalise i-voids ngaphakathi kwe-capacitor.Ineempawu ezibalaseleyo zombane kunye nezomzimba kwaye ihambelana kakuhle nezinye izinto kwi-capacitor.

Iimeko zokusebenza:

Ukuphakama akudluli kwi-1000m, ubushushu be-ambient yi-40/B, kwaye ubushushu obuphezulu beKlasi B ngu +45℃.Indawo yofakelo ayinakungcangcazela ngoomatshini, akukho rhasi inobungozi kunye nomphunga, akukho luthuli okanye uqhushumbo.Ii-capacitors kufuneka ziqinisekiswe ukuba zisebenza phantsi kweemeko ezifanelekileyo zokungenisa umoya, kwaye azivumelekanga ukuba zisebenze phantsi kweemeko ezivaliweyo nezingenamoya.I-wiring ye-capacitors kufuneka ibe ngabaqhubi abaguquguqukayo, kwaye isiphaluka sonke kufuneka sidibanise kakuhle.

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.
