Nhamba yechikamu chekusiyanisa

Inogona kukamurwa kuva matatu-phase transformer uye single-phase transformer.Mune matatu-phase simba system, iyo yakajairika yetatu-phase transformer, kana iyo yakakura uye yakaganhurirwa nemamiriro ekufambisa, muchikamu chetatu-simba system inogona kushandiswa kune matatu single-phase transformer composition transformer group.

Mhepo yekusiyanisa

Inogona kukamurwa kuita kaviri mhepo inotenderedza transformer uye matatu mhepo inotenderera transformer.Kazhinji transformers ane kaviri-mamhepo transformers, ndiko kuti, pane maviri windings pamusoro simbi musimboti, imwe ndiyo yepakutanga mhepo, imwe yechipiri mhepo.Tri-winding transformers ihombe-inotakura magemhu (pamusoro pe5600 kVA) inoshandiswa kubatanidza mitsara mitatu yakasiyana yekufambisa magetsi.Muzviitiko zvakakosha, kunewo maSaton transformers anoshandisa mamwe windings.

Kurongeka kwechimiro

Inogona kukamurwa kuita iron-core transformer uye iron-shell transformer.Kana iyo inotenderedza pasuru iri mupakati periphery iri musimboti mhando transformer;Kana iyo simbi yesimbi yakaputirwa kumativi emhepo inoputika, inenge iine iron-clad transformer.Iwo maviri akasiyana zvishoma muchimiro, asi hapana mutsauko wakakosha musimboti.Magetsi emagetsi ndeemhando yepamusoro.

Iyo transformer inonyanya kuumbwa nesimbi musimboti, mhepo, tangi yemafuta, piro yemafuta, insulation bushing, tap switch uye gasi relay.

Iron core

Iyo iron core ndiyo magineti yedunhu chikamu che transformer.Hysteresis kurasikirwa uye eddy yazvino kurasikirwa inogadzirwa panguva yekushanda.Kuitira kuderedza kupisa kurasikirwa uye kuwanda uye uremu, iyo musimboti inoumbwa neinotonhora-yakakungurutswa zviyo yakatarisana nesilicon simbi sheet ine yakakwirira magineti. conductivity isingasviki 0.35mm. Maererano nekurongeka kwemhepo mukati mepakati, kune mhando yemhando uye shell shell.

Mune transformer yehukuru hukuru, kuitira kuti kupisa kunokonzerwa nekurasikirwa kwesimbi musimboti kunogona kutorwa zvizere nemafuta anodzivirira panguva yekutenderera, kuitira kuti uwane yakanaka kutonhora mhedzisiro, inotonhorera chiteshi chemafuta chinowanzo kupihwa mukati. musimboti wesimbi.

The winding

Iyo inomonereka uye yesimbi musimboti ndiyo yakakosha zvikamu zvetransformer.Nemhaka yokuti kune kushorwa mumhepo pachayo kana kupikisa kupikisa mujoka, kupisa kunofanira kugadzirwa nemutemo waJoule.Naizvozvo, kuputika hakugoni kudarika ikozvino yakakwirira kudarika yakarongwa ikozvino kwenguva yakareba.Uye zvakare, iyo pfupi-yedunhu ikozvino inoburitsa yakakura simba remagetsi pamhepo uye kukuvadza iyo transformer.Yayo yekutanga mhepo ine concentric mhando uye inopindirana mhando mbiri.

The chikuru kukanganisa transformer windings ipfupi redunhu pakati kutendeuka uye pfupi redunhu kuti goko.Interturn pfupi dunhu rinonyanya nokuda insulation kuchembera, kana nokuda transformer overload uye kuburikidza pfupi redunhu insulation kubudikidza kukuvara kwemichina.Iyo mafuta epamusoro mu transformer inodonha, kuitira kuti mhepo ionekwe pairi pevhu, kutenderedza kupfupi dunhu kunogonawo kuitika; Uye zvakare, kana uchipfuura nepakati pfupi, nekuda kwekupfuura-ikozvino mhedzisiro yemhepo deformation, kuitira kuti Insulation is mechanical damage, ichaitawo inter-turn short circuit.Panyaya ye interturn short circuit, ikozvino mumhepo ipfupi inotenderera inogona kudarika kukosha kwakarongwa, asi ikozvino mumhepo yose inogona kusapfuura kukosha kwakarongwa.Muchiitiko ichi, chiito chekudzivirira gasi, mamiriro ezvinhu akakomba, iyo yakasiyana-siyana yekudzivirira chigadziro ichavawo mukuita.Chikonzero chekupfupika kwegomba kunokonzerwawo nekuchembera kwekudzivirira kana kunyorova kwemafuta, kudonha kwemafuta, kana nekuda kwemheni uye. kushanda overvoltage.Uye zvakare, kana ichipfuura nepakati pfupi dunhu inoitika, iyo inotenderedza ichave yakaremara nekuda kwe-over-current, uye iyo pfupi yedunhu chiitiko ichaitikawo kune goko.Kana goko racho riri pfupi redunhu, rinowanzo kuita kwegasi kudzivirira mudziyo uye kuita kwekudzivirira pasi.

Tangi yemafuta

Muviri (kupeta uye iron core) yemafuta-akanyudzwa transformer inoiswa mutangi yemafuta yakazadzwa nemafuta ekushandura, uye tangi yemafuta inoshongedzwa nesimbi mahwendefa.Iyo tangi yemafuta yepakati uye diki transformer inoumbwa nebhokisi shell uye bhokisi chivharo.The transformer body inoiswa mubhokisi shell.Chivharo chebhokisi chinogona kuvhurwa kuti chisimudzwe kunze kwemuviri kuitira kuchengetedza.

Maitiro ekugadzirisa kutaura

A. Pamusoro pewaya yemhangura yehudiki hudiki, iyo yakaderera-voltage inomonereka yemafuta-yakanyudzwa transformer kazhinji inotora humburumbira yefoil yemhangura yakatenderedza shaft;Iyo yakakwira-voltage inotenderera inotora akawanda-layer cylinder chimiro, kuitira kuti kugovera kweampere-kutendeuka kwakaenzana, iyo magineti leakage idiki, iyo mechanical simba rakakwirira, uye pfupi-circuit kushorwa kwakasimba.

B. Matanho ekutsanya anogamuchirwa kune iyo core uye mhepo inoenderana.Kusimbisa zvikamu senge kureba kwechishandiso uye yakaderera-voltage lead wire zvese zvakashongedzerwa ne-self-locking anti-loosening nzungu, uye chimiro chisina kusimudza musimboti chinogamuchirwa kuti chimire kuvhunduka kwekufambisa.

C. Coil uye musimboti kushandisa vacuum kuomesa, transformer mafuta kushandisa vacuum mafuta sefa uye mafuta jekiseni muitiro, kuitira kuti transformer yomukati mwando kuti zvishoma.

D. Tangi yemafuta inotora pepa rakasvibiswa, iro rine basa rekufema rinobhadhara kuchinja kwehuwandu hwemafuta kunokonzerwa nekushanduka kwekushisa, saka chigadzirwa chacho hachina mafuta ekuchengetedza tangi, izvo zviri pachena kuti zvinoderedza kureba kwe transformer.

E. Nokuti pepa remarara rakatsiva tangi rekuchengetedza mafuta, mafuta e-transformer ari oga kubva kune dzimwe nyika, kuitira kuti zvibudirire kudzivirira kupinda kweokisijeni nemvura uye zvichiita kuti kuderera kwekushanda kwekudzivirira.

F. Maererano nemashoko mashanu ari pamusoro apa, mafuta-akanyudzwa transformer haafaniri kushandura mafuta mukushanda kwemazuva ose, iyo inoderedza zvikuru mari yekuchengetedza ye transformer uye inowedzera hupenyu hwebasa rekushandura.
