02 Kev tsim khoom
2.1 Core
Lub transformer ua los ntawm lub tiaj tus coil hlau core muaj ib tug kiag li kaw sib nqus Circuit Court yam tsis muaj hlau nplaum to. Hais txog cov khoom siv raw, SCOTECH txais yuav lub ntiaj teb thawj-chav kawm siab- zoo taw qhia silicon steel ntawv, uas yog nyias nyias thiab muaj cov yam ntxwv ntawm siab sib nqus induction thiab tsis tshua muaj hlau tsis zoo, ua kom muaj kev ua haujlwm zoo ntawm cov tub ntxhais hlau. Nyob rau hauv cov nqe lus ntawm cov qauv, lub tiaj tus coil core yog symmetrically raug mob nrog txawv dav thiab txheej, thiab tus ntoo khaub lig seem yog ib tug symmetrical kauj ruam kwv yees li ncig. Thaum siv nyob rau hauv transformers, lub kauj tuaj yeem raug mob ncaj qha rau ntawm cov tub ntxhais hlau, yog li txo qhov coil tig ntev.
2.2 Cua txias
Tsawg-voltage foil winding yog hais txog kev siv cov ntawv hlau nyias los ua cov khoom siv hluav taws xob, los ntawm kev sib tshooj ntawm txoj kev mus rau cua. Txoj kev no feem ntau yog siv nyob rau sab qis voltage ntawm lub transformer. Foil winding siv thaj chaw loj ntawm tus neeg xyuas pib kom txo cov coil tsis kam thiab eddy tam sim no poob, tshwj xeeb tshaj yog nyob rau hauv tsawg- daim ntawv thov zaus. Foil winding siv thaj chaw loj ntawm tus neeg xyuas pib kom txo cov coil tsis kam thiab eddy tam sim no poob, tshwj xeeb tshaj yog nyob rau hauv tsawg- daim ntawv thov zaus. Cov qauv ntawm cov ntawv ci winding yog cov compact, uas muaj peev xwm ua tau ntau dua hluav taws xob conductivity nyob rau hauv ib tug txwv qhov chaw, uas yog tshwj xeeb tshaj yog tseem ceeb rau me me transformers. Cov ntawv ci- cov qauv kab mob tuaj yeem tiv thaiv kev cuam tshuam ntawm electromagnetic cuam tshuam thiab txo cov suab nrov electromagnetic, yog li txhim kho kev ua haujlwm ruaj khov ntawm transformer.
High-voltage wire winding yog hais txog kev siv lub voj voog lossis lub voj voos xaim rau winding, feem ntau yog siv nyob rau hauv siab -voltage sab ntawm transformer. High voltage xaim winding siv cov khoom siv rwb thaiv tsev coated hlau, tuaj yeem tiv taus hluav taws xob ntau dua, nrog kev rwb thaiv tsev zoo dua, tsim nyog rau kev ua haujlwm siab. Cov hlau- cov qauv kab mob yog qhov muaj zog thiab tuaj yeem tiv taus qhov cuam tshuam ntawm ib puag ncig sab nraud, xws li ya raws thiab qhov kub thiab txias hloov pauv, ncua kev pab cuam lub neej ntawm transformer. High voltage hlau winding tuaj yeem tsim raws li qhov sib txawv thiab cov duab kom tau raws li qhov yuav tsum tau muaj ntawm ntau lub tshuab hluav taws xob.
2.3 Tank
Cov roj tank raug txiav, xuas nrig ntaus thiab khoov los ntawm cov khoom siv laser lej tswj kom paub tseeb tias kev ua haujlwm raug. Qhov saum npoo ntawm lub thawv txais kev tiv thaiv kev tiv thaiv- tsim kev xeb thiab kev kho tshwj xeeb tshuaj pleev xim, uas tsim nyog rau ntau qhov chaw hnyav. Sab saum toj ntawm lub thawv tuaj yeem raug tso tawm, thiab lub kaum sab xis ntawm lub hau npog sab saum toj tsis pub tsawg dua 3 degree.
