Resin-insulated Dry-type Transformer SCB18-2000/10
Dry transformer imhando yesimba rekushandura rakasiyana neoiri-immersed transformer, oiri-immersed transformer ndiko kushandiswa kwemafuta etransformer yekuvharisa uye kupisa kupisa, asi iyo yekuvharisa iyo yakaoma transformer inonyanya kuvharwa inoumbwa ne epoxy resin kudurura.
1. Iron Core
(1) Iron core structure. Iyo simbi yesimbi yeakaoma transformer inhengo yemagineti yedunhu, iyo inoumbwa nezvikamu zviviri: iron core column uye joko resimbi. Iyo mhepo inoputirwa pamutsara wepakati, uye joko rinoshandiswa kuvhara iyo yese magnetic circuit. Chimiro chepakati chinogona kugoverwa mumapoka maviri: core type uye shell type. Iyo yepakati inoratidzwa nejoko resimbi pamusoro uye pasi pemhepo, asi haitenderere padivi pemhepo; Shell core inoratidzirwa nejoko resimbi rinotenderedza kwete chete kumusoro uye pasi mativi emhepo, asiwo mativi emhepo. Nekuti iyo yepakati dhizaini iri nyore, iyo inomonereka dhizaini uye insulation zvakare yakanaka, saka magetsi eChina anoomesa emagetsi anonyanya kushandisa musimboti, chete mune mamwe akasarudzika akaoma transformer (seyemagetsi choto chakaoma transformer) kushandisa shell core.
(2) Iron core material. Nekuti iyo musimboti wesimbi ndiyo yemagineti yedunhu reiyo yakaoma type transformer, zvinhu zvayo zvinoda yakanaka magineti permeability, uye chete yakanaka magineti permeability inogona kuita kuti kurasikirwa kwesimbi kuve kudiki. Naizvozvo, musimboti wesimbi weiyo yakaoma transformer inogadzirwa nesilicon simbi sheet. Kune marudzi maviri esilicon simbi sheet: inopisa yakakungurutswa uye inotonhora yakakungurutswa simbi sheet. Nekuti simbi inotonhora-yakakungurutswa simbi ine yakakwira permeability uye diki kurasikirwa kweyuniti kana ichiita magineti painotenderedza nzira, kuita kwayo kuri nani pane kuya kwesimbi inopisa-yakakungurutswa simbi, uye epamba yakaoma ma transformer ese anoshandisa inotonhora-yakakungurutswa simbi simbi silicon simbi sheet. Ukobvu hwepamba inotonhora yakakungurutswa simbi pepa ndeye 0.35, 0.30, 0.27mm uye zvichingodaro. Kana shiti racho rakakora, kurasikirwa kwazvino kwakakura, uye kana pepa iri rakatetepa, iyo lamination coefficient idiki, nekuti pamusoro pesilicon simbi sheet inofanira kuputirwa nejira re insulating pendi kuti insulate pepa kubva pane chimwe chidimbu. kune mumwe.
2. Kupeta mhepo
Iyo inomonereka ndiyo yedunhu chikamu cheyakaoma-mhando transformer, iyo inowanzo gadzirwa ine insulated enameled, bepa-yakaputirwa aluminium kana waya yemhangura inodzingwa.
Zvinoenderana nekurongeka kwakasiyana kweakakwira uye yakaderera voltage windings, iwo mamhepo anogona kukamurwa kuita concentric uye rhomboid. Kune concentric windings, kuitira kuti zvive nyore kuvharidzira pakati pemhepo uye nheyo, iyo yakaderera-voltage winding inowanzoiswa pedyo nechepakati mbiru: kune inopindirana windings. Kuti uderedze kureba kwekudzivirira, iyo yakaderera-voltage mhepo inowanzoiswa padyo nejoko.
3: Insulation
Iyo huru insulating zvinhu mukati yakaoma transformer oiri yakaoma transformer, insulating kadhibhodhi, cable bepa, corrugated bepa uye zvichingodaro.
4. Tap Changer
Kuti upe magetsi akagadzikana, kudzora kuyerera kwemagetsi kana kugadzirisa mutoro wekupokana ikozvino, zvinodikanwa kugadzirisa voltage yeakaoma transformer. Parizvino, iyo nzira yekugadziriswa kwevoltage yeakaoma-mhando transformer ndeyekumisa pombi kune rimwe divi remhepo kucheka kana kuwedzera chikamu chemhepo inotenderera kushandura huwandu hwekutendeuka kwemhepo, kuitira kuti uwane nzira graded voltage kugadzirisa nekushandura voltage ratio. Dunhu umo mhepo inodhonzerwa uye kubatwa kuti iite voltage regulation inonzi voltage regulation circuit; Switch inoshandiswa kuchinja pombi kugadzirisa pressure inonzi tap switch. Kazhinji, danho rinotevera nderekudhirowa tepi yakakodzera pane yakakwira voltage winding. Izvi zvinodaro nekuti iyo yakakwira voltage mhepo inowanzoiswa kunze, inotungamira kune pombi iri nyore, chechipiri, iyo yakakwira voltage padivi ikozvino idiki, ikozvino inotakura chikamu chepombi inotungamira uye chenji chepombi idiki, uye yakananga kubata kweiyo. chinja zvakare inogona kugadzirwa.
Iyo voltage regulation yedivi rechipiri re transformer yakaoma isina mutoro wekuremerwa, uye chikamu chekutanga chakabviswawo kubva kune gidhi remagetsi (hapana simba rekusimudzira), inonzi iyo voltage regulation pasina excitation, uye iyo voltage regulation nekuremerwa kwekupokana kwekushandura mhepo. tapping.
