Resin-insulated Qhuav hom Transformer SCB18-2000/10

Qhuav transformer yog ib hom fais fab transformer sib txawv ntawm cov roj-immersed transformer, roj-immersed transformer yog siv cov roj transformer rau rwb thaiv tsev thiab tshav kub dissipation, tab sis cov ntaub ntawv rwb thaiv tsev ntawm qhuav transformer feem ntau yog cov rwb thaiv tsev tsim los ntawm epoxy resin pouring.

(1) Hlau core qauv. Cov tub ntxhais hlau ntawm lub tshuab ziab khaub ncaws qhuav yog ib feem ntawm cov hlau nplaum sib nqus, uas yog tsim los ntawm ob ntu: ib qho hlau core kem thiab ib tug quab hlau. Lub winding yog ntim rau ntawm cov tub ntxhais kem, thiab tus quab yog siv los kaw tag nrho cov khoom sib nqus. Cov qauv ntawm cov tub ntxhais feem ntau tuaj yeem muab faib ua ob pawg: hom tub ntxhais thiab hom plhaub. Cov tub ntxhais yog tus cwj pwm los ntawm ib tug quab hlau tiv thaiv sab saum toj thiab hauv qab ntawm lub winding, tab sis tsis nyob ib puag ncig ntawm lub winding; Plhaub tub ntxhais yog tus cwj pwm los ntawm ib tug yoke hlau uas nyob ib puag ncig tsis tau tsuas yog sab saum toj thiab hauv qab ntawm lub winding, tab sis kuj sab ntawm winding. Vim hais tias cov txheej txheem tseem ceeb yog qhov yooj yim, qhov winding layout thiab rwb thaiv tsev kuj tseem zoo, yog li Tuam Tshoj lub zog qhuav transformers feem ntau siv cov tub ntxhais, tsuas yog qee qhov tshwj xeeb qhuav transformers (xws li hluav taws xob rauv qhuav transformer) siv plhaub core.

(2) Cov khoom siv hlau. Vim hais tias cov tub ntxhais hlau yog cov hlau nplaum ntawm lub tshuab ziab khaub ncaws, nws cov khoom yuav tsum muaj cov hlau nplaum zoo permeability, thiab tsuas yog cov hlau nplaum zoo permeability tuaj yeem ua rau cov hlau tsis zoo. Yog li ntawd, cov tub ntxhais hlau ntawm qhov qhuav transformer yog ua los ntawm silicon steel ntawv. Muaj ob hom silicon steel ntawv: kub dov thiab txias dov steel ntawv. Vim hais tias cov ntawv txias-dov steel muaj ntau dua permeability thiab me me poob thaum magnetizing raws dov kev taw qhia, nws cov kev ua tau zoo dua li ntawm cov ntawv kub dov steel, thiab domestic qhuav transformers tag nrho siv txias dov steel ntawv silicon steel ntawv. Lub thickness ntawm domestic txias dov steel ntawv yog 0.35, 0.30, 0.27mm thiab hais txog. Yog tias daim ntawv tuab, qhov eddy tam sim no poob loj, thiab yog tias daim ntawv nyias nyias, lub lamination coefficient me me, vim tias cov ntawv ntawm silicon steel yuav tsum tau coated nrog ib txheej ntawm cov xim insulating kom insulate daim ntawv ntawm ib daim. rau lwm tus.

Lub winding yog ib feem ntawm lub tshuab hluav taws xob qhuav, uas feem ntau yog ua los ntawm insulated enameled, ntawv qhwv aluminium lossis tooj liab hlau raug rho tawm haujlwm.

Raws li kev sib txawv ntawm qhov siab thiab qis voltage windings, cov windings tuaj yeem muab faib ua concentric thiab rhomboid. Rau concentric windings, txhawm rau pab txhawb kev rwb thaiv tsev ntawm cov winding thiab cov tub ntxhais, qhov qis-voltage winding feem ntau yog muab tso rau ze ntawm cov tub ntxhais: rau overlapping windings. Txhawm rau txo qhov kev ncua deb ntawm rwb thaiv tsev, qhov qis-voltage winding feem ntau yog muab tso ze rau ntawm tus quab.

Lub ntsiab insulating cov ntaub ntawv nyob rau hauv qhuav transformer yog qhuav transformer roj, insulating cardboard, cable ntawv, corrugated ntawv thiab hais txog.

Txhawm rau muab qhov hluav taws xob ruaj khov, tswj lub zog ntws los yog kho qhov kev tiv thaiv tam sim no, nws yog ib qho tsim nyog los kho qhov voltage ntawm qhuav transformer. Tam sim no, txoj kev hloov voltage ntawm qhuav-hom transformer yog teem kais rau ntawm ib sab ntawm lub winding los txiav los yog nce ib feem ntawm winding lem los hloov tus naj npawb ntawm lem ntawm winding, thiaj li mus cuag tus txheej txheem ntawm winding. graded voltage hloov los ntawm kev hloov qhov voltage piv. Lub Circuit Court uas lub winding yog kos thiab tapping rau voltage tswj yog hu ua voltage regulation circuit; Qhov hloov siv los hloov tus kais dej los kho lub siab yog hu ua tus kais hloov. Feem ntau, cov kauj ruam tom ntej yog kos tus kais tsim nyog ntawm lub siab voltage winding. Qhov no yog vim hais tias lub high voltage winding yog feem ntau teem rau sab nraum, ua rau lub kais yog yooj yim, qhov thib ob, lub high voltage sab tam sim no yog me me, tam sim no nqa ib feem ntawm cov kais dej thiab cov kais hloov pauv yog me me, thiab kev sib cuag ncaj qha ntawm lub switch kuj tseem yuav raug tsim.

Kev tswj hluav taws xob ntawm qhov nruab nrab ntawm lub tshuab hluav taws xob qhuav tsis muaj qhov tsis kam thauj khoom, thiab cov thawj sab tseem raug cuam tshuam los ntawm daim phiaj hluav taws xob (tsis muaj hluav taws xob excitation), yog hu ua kev tswj hluav taws xob tsis muaj zog, thiab kev tswj hluav taws xob nrog kev sib tw rau kev hloov pauv winding. tapping.
