1.4 Core Technical Highlights
Lub transformer nta siab - zoo tooj liab windings, boosting hluav taws xob conductivity thiab txo lub zog poob. Ntawm qhov qis-voltage sab, 10- qhov bushing ua ke nrog lub zog txhawb nqa kom ntseeg tau tias cov windings nyob ruaj khov, txawm tias muaj kev ntxhov siab lossis kev co. Qhov kev xav zoo no txhim kho kev ntseeg tau ntev thiab ruaj khov, ua kom cov kev sib txuas ruaj khov thiab lub tshuab hluav taws xob ua haujlwm tau zoo nyob rau ntau xyoo ntawm kev ua haujlwm.
Siv peb lub-theem, peb-limb core, no transformer maximizes magnetic efficiency thaum txo qhov poob. Txhua theem muaj nws tus kheej ntsug limb, uas tso cai rau sib nqus flux ntws seamlessly thiab txo cov suab nrov acoustic thiab kev co. Nws tsis yog hais txog kev siv hluav taws xob nkaus xwb- cov qauv kuj tseem txhim kho kev ua haujlwm ntawm kev cia siab thiab ua rau lub tshuab hluav taws xob nyob ntsiag to, ruaj khov, thiab ua haujlwm tau zoo, tsis hais lub nra.
Nruab nrog plaub - txoj haujlwm thauj khoom tawg hloov, qhov hloov pauv no tuaj yeem hloov pauv cov kev xav tau yooj yim. Nws ua tau -hauv bayonet fuse thiab ELSP fuse muaj kev tiv thaiv ntxiv, tiv thaiv kev hla dhau thiab luv luv. Dyn1 vector pawg ntxiv kom ntseeg tau tias kev sib raug zoo nrog lub network thaum tswj kev nyab xeeb, txhim khu kev qha. Ua ke, cov yam ntxwv no muab cov neeg ua haujlwm tswj hwm thiab ntseeg siab.
Lub tank roj yog tsim los ntawm siab-lub zog qis- carbon steel thiab coated nrog ntau yam los tiv thaiv- cov khaubncaws sab nraud povtseg, tsim los tiv thaiv kev sim ntawm lub sijhawm. Automated welding xyuas kom airtight sealing thiab cov qauv kev ruaj ntseg, thaum lub tank qhov ntev thiab tsim tau tsim los ua kom zoo dua cov cua sov dissipation. Txhua qhov kev nthuav dav, los ntawm kev xaiv cov khoom siv rau txheej txheej, yog txhais tau tias kom lub tshuab hloov pauv kom txias, ruaj khov, thiab teeb meem - dawb.
02 Kev tsim khoom
2.1 Core
Txais yuav peb-theem, peb-limb core tsim, qhov transformer no muab kev txhim kho zoo kawg nkaus rau kev ua haujlwm sib nqus thiab kev ua haujlwm tag nrho. Nrog rau txhua theem mob siab rau kev sib cais ntsug limb, qhov kev teeb tsa txo qis cov tub ntxhais poob ntau heev thaum ua kom muaj seamless sib nqus flux propagation. Tshaj li kev txhim kho lub zog hloov pauv kev ua tau zoo thiab kev txhawb nqa qhov kev cia siab, qhov kev tsim qauv no kuj txo cov suab nrov emissions thiab mechanical oscillations thoob plaws hauv nws lub neej ua haujlwm.
2.2 Cua txias
Winding Design: Txhua theem muaj ntau yam insulated hlau coils, nrog rau cov lem suav adjustable kom meej specifications kom ua tau raws li qhov xav tau voltage piv. Kev sib txuas layouts suav nrog ob lub tswv yim tseem ceeb: lub hnub qub (Y) teeb tsa, qhov kawg ntawm txhua qhov winding converges ntawm ib qho kev sib koom nruab nrab ntawm - ua kom zoo rau cov tshuab uas xav tau kev sib txuas nruab nrab- thiab delta (Δ) kev npaj, uas txuas windings nyob rau hauv ib tug kaw series voj voog los ntawm kev koom nrog rau qhov kev txiav txim siab rau theem tom ntej. siab -scenarios zog. Raws li kev rwb thaiv tsev, qib siab - cov ntaub ntawv qib siab xws li polyester zaj duab xis thiab epoxy resin tau muab tso ua ke kom xa cov hluav taws xob sib cais, tiv thaiv kev luv luv thiab txhawb kev ua haujlwm los ntawm kev txwv lub zog dissipation.
2.3 Tank
Crafted los ntawm siab -tensile low- carbon steel, lub transformer roj tank boasts ib tug tshwj xeeb conditioned nto uas ua rau kom coating adherence, thaum automated welding txheej txheem yog siv nyob rau hauv tag nrho cov sib dhos los xyuas kom meej zoo weld zoo thiab airtight sealing kev ntseeg tau. Rau kev txhim kho ntev - lub sij hawm durability, nws cov phab ntsa sab hauv yog coated nrog ntau - txheej los tiv thaiv- corrosive tiav, thiab lub tank qhov ntev tsis thiab cov qauv geometry yog tailor-tsim kom phim lub transformer qhov tshwj xeeb ntsuas qhov yuav tsum tau ua - ntxiv rau kev ua kom sov thiab ua kom zoo dua.
2.4 Lub Rooj Sib Tham Kawg
Tom qab cov tub ntxhais thiab cov windings tau txais kev sib dhos thiab kev teeb tsa zoo - nrog rau txhua qhov kev sib txuas tau raug lees paub rau qhov tseeb - cov roj tank tau ruaj khov thiab ntim nrog cov kua dej insulating ntawm cov qib teev tseg. Tom ntej no, kev txiav hluav taws xob rau ob qho tib si siab-voltage thiab qis-voltage sab yog ua raws li kev ua raws cai nruj, thiab cov txheej txheem xaus nrog kev koom ua ke ntawm cov khoom siv tseem ceeb: kub sensors, siab nyem li qub, thiab roj qib ntsuas, thiab lwm yam.
