Ingcaciso yeMveliso

Olu hlobo lwe-coil yokukhupha lusetyenziswe kwinkqubo yamandla ye-6-10KV AC 50Hz, ngokuhambelana nebhanki ye-capacitor yamandla, kwaye isetyenziselwa ukukhupha xa umbane ucinyiwe ukuqinisekisa ukhuseleko lwezixhobo kunye nokhuseleko lwabasebenzi bokulondoloza.
Olu hlobo lwekhoyili yokukhupha lunomzimba kwitanki yamafutha.Umbindi wentsimbi womzimba luhlobo lwentsimbi lwangaphandle, olufakwe kwi-silicon sheet sheet.Iikhoyili eziphambili kunye nesekondari zifakwe kwisiqu sokulinganisa umgca okanye ukhuseleko.Kukho amatyholo amabini oxinzelelo oluphezulu kunye nezihlahla ezine zoxinzelelo oluphantsi kwi-tank cover.Umzimba ugxininise kwikhava yebhokisi, kunye nebhokisi lebhokisi linikezelwa ngevalve yokukhupha umoya, isakhiwo sonke sihlangene kwaye i-insulation ilungile.

Iimpawu zemveliso kunye nobungakanani bokusetyenziswa

1. Olu hlobo lwekhoyili yokukhupha luthatha isakhiwo esiqinileyo esitywinwe ngokupheleleyo kunye nokusebenza okuthembekileyo kokutywinwa.Yamkela i-vacuum epheleleyo yokumisa kunye nenaliti yeoli ukuqinisekisa ukuba i-oyile ekhuselayo ihlukaniswe ngokupheleleyo nomoya wangaphandle.Indlela yembuyekezo ye-oyile yokugquma ithatha itekhnoloji yembuyekezo enelungelo elilodwa lomenzi wechiza.Ngethuba lokusebenza kwekhoyili yokukhupha unyaka wonke, ibhokisi ihlala igcina uxinzelelo oluncinci (olona luphezulu alukho ngaphezu kwe-0.05Mpa, kwaye ubuncinci abukho ngaphantsi kwe-0.001Mpa)
2. Onke amalungu anentsebenzo entle yokutywina.Akukho kugcinwa okanye ukutshintshwa kweendawo ezifunekayo ngexesha lobomi obulindelekileyo, kwaye inomsebenzi wobungqina bokuqhuma, okuyimveliso engenakugcinwa.
3. Iiparamitha zoyilo zinesiqalo esiphezulu kunye nezinga eliphezulu lokuchaneka.Izinga lokuchaneka liqinisekisiwe kwi-0.9-1.3 amaxesha ombane olinganisiweyo kunye no-0-50VA ulinganiswe umthwalo wesibini (cos yi-0.8 lag).Isakhiwo sonke sinengqiqo, ukusebenza kuhle kakhulu, umthamo uncinci, kwaye imilo intle.
4. Ibhanki ye-capacitor ehambelanayo ihlanganisa uluhlu olubanzi, okwenza lula ukhetho oludlulileyo oluhambelanayo kunye nokusebenza.

Iimeko zokusebenza:

1. Ubushushu be-ambient yi-40 ° C kunye ne-40 ° C, umswakama ohambelanayo ngu-85%, ukuphakama akudluli i-1000 yeemitha, kwaye ifakwe ngaphandle.
2. Indawo yofakelo kufuneka ingabinarhasi eyonakalisayo, i-steam, iidiphozithi zeekhemikhali, uthuli, ukungcola kunye neendawo ezingenayo i-vibration enamandla.
3. Iqokobhe lekhoyili yokukhupha kufuneka limiswe ngokuthembekileyo.

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.
