Siab -Kev Ua Tau Zoo Traction Transformers – Engineered for Speed & Safety!

5 MVA traction transformer tau xa mus rau Canada hauv 2025. Lub zog ntsuas ntawm lub transformer yog 5000 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 44 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 6.6 kV, lawv tsim ib pawg vector ntawm Dyn11.

Lub tshuab hluav taws xob traction no yog tsim los ua kom tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob ntawm traction substations, muab hluav taws xob rau 11 kV thiab 6.6 kV kis kab mob. Nws nta qhov zoo - qauv tsim nrog cov khoom siv tshwj xeeb, suav nrog tsis muaj - load kais - hloov pauv, detachable kub - dip galvanized radiators, thiab ntau yam li qub thiab saib xyuas cov khoom siv. Lub tank transformer yog tsim los ntawm steel daim hlau (Ntau tshaj los yog sib npaug rau 6 hli rau lub tank, 16 hli rau hauv qab phaj) thiab muaj ib tug rational layout ntawm (bushings), rods, thiab terminals (nrog cov diameters teev rau sib txawv kev sib txuas). Kev txiav txim siab tshwj xeeb yog muab rau kev sib haum xeeb, kev siv lub zog ntawm windings, thiab tiv thaiv - kev ua qias tuaj (nrog cov qauv xim thiab cov pa phem - resistant thickness). Nws yog engineered los xyuas kom meej kev lag luam txhim khu kev qha, txuag hluav taws xob zoo, thiab kev saib xyuas yooj yim, ua lub luag haujlwm tseem ceeb hauv kev siv hluav taws xob traction.

5000 kVA traction transformer daim duab kos duab thiab loj.

Lub traction transformer siv peb -theem peb-limb stacked laminated core, tsim los ntawm nyias silicon steel laminations (0.23-0.35mm) nrog insulated coatings kom txo tau eddy tam sim no poob. Precision-stacked nrog cov kauj ruam- lap joints, tsim kom ntseeg tau tias tsis muaj -load poob, sib npaug flux tis, thiab siab mechanical zog tiv thaiv railway kev co. Nws lub compact peb -limb qauv optimizes sib nqus efficiency thaum txo qhov hnyav, ua rau nws zoo tagnrho rau siab -kev ua tau zoo traction fais fab.

Lub traction transformer siv txuas ntxiv winding rau kev ua haujlwm zoo hauv kev thov kev tsheb ciav hlau. Cov qauv tsim muaj zog no muaj cov kab sib txuas sib txuas uas muab cov cuab yeej tshwj xeeb los tiv thaiv kev vibration thiab luv luv - lub zog hluav taws xob, thaum tswj xyuas cov yam ntxwv ntawm hluav taws xob. Lub winding lub ntsug roj ducts xyuas kom txias txias, thiab nws cov transposed conductor siv minimizes eddy tam sim no poob. Lub nruam disc configuration muaj superior surge voltage withstand peev xwm thiab uniform kub tis, ua rau nws zoo tagnrho rau tuav lub nquag load variations inherent nyob rau hauv traction zog systems. Qhov no compact tab sis ruaj winding tov ua ke nrog kev ntseeg siab nrog high hluav taws xob thiab thermal kev ua tau zoo.

Lub traction transformer nta grey - pleev xim rau lub tank nrog dawb - xim conservator (roj tank), ua kom pom tseeb pom tseeb. Lub tank yog tsim los nrog kub dip galvanized tshem tawm radiators rau txhim kho corrosion kuj thiab npaum tshav kub dissipation.

Rau kev saib xyuas kev nkag mus, kev tshuaj xyuas cov npog lossis cov manholes yog ruaj ruaj nrog bolts thiab gasket seals los tiv thaiv cov roj to. Txhua lub hau npog yog nruab nrog lub zog lifting handles kom muaj kev nyab xeeb thiab yooj yim tshem tawm thaum ua haujlwm.

Cov qauv tsim muaj zog no ua kom ruaj khov, huab cua tsis kam, thiab kev saib xyuas yooj yim hauv kev xav tau kev tsheb ciav hlau ib puag ncig.

1. Winding Assembly:Swb ua ntej-fabricated LV (tsawg-voltage) thiab HV (siab-voltage) windings mus rau hauv cov tub ntxhais, ua kom muaj kev sib raug zoo ntawm cov khoom siv rwb thaiv tsev (spacers, blocks) thiab ceev cov windings.

Lub transformer yog ruaj ruaj nyob rau hauv ib tug reinforced ntoo crate siv bolts los yog steel straps, nrog rau tej yam yooj yim xws li bushings qhwv nyob rau hauv poob siab - cov khoom absorbing. Lub tank yog roj- puv lossis puv nrog cua qhuav / nitrogen, thiab lub crate yog lined nrog noo noo- cov ntaub ntawv pov thawj thiab kaw nrog cov ntaub ntawv tsis muaj dej. Cov qauv ntoo ruaj khov nta forklift slots / lifting lugs, steel band reinforcement, thiab sloped rain cover.

Cov cim sab nraud suav nrog qhov hnyav, qhov ntev, tuav cov cim, thiab cov ntawv cim kev phom sij, thaum cov ntaub ntawv sab hauv (cov ntawv ntim, phau ntawv qhia, cov ntawv xeem) tau muab khaws cia rau hauv lub hnab ntim dej.

Lub transformer yog ruaj ntseg loaded mus rau ib tug flatbed tsheb thiab thauj mus rau qhov chaw nres nkoj ntawm cov khoom xa tuaj. Rau CIF cov ntsiab lus, tus neeg muag khoom tuav lub hiav txwv freight, nrog rau booking ib lub nkoj tsim nyog nrog kom ruaj khov (xws li, twist locks rau ntim lossis lashing rau breakbulk). Cov ntoo crate yog stowed kom tsis txhob ya raws, nrog kev poob siab / kev co taw qhia txuas. Kev tuav pov hwm them rau cov kev pheej hmoo hauv hiav txwv (Txhua Yam Kev Nyab Xeeb rau ICC Clause A). Thaum tuaj txog ntawm qhov chaw nres nkoj Durban, cov khoom thauj tau raug tshem tawm siv cov chaw nres nkoj cranes, tshem tawm los ntawm kev lis kev cai (tus neeg muag khoom npaj cov ntaub ntawv xa tawm; tus neeg yuav khoom lag luam tshem tawm), thiab xa mus rau tus neeg muag khoom qhov chaw teev tseg. Cov trailer tshwj xeeb yuav xav tau rau cov chav loj loj.

Raws li lub hauv paus ntawm kev tsheb ciav hlau traction thiab lub zog hluav taws xob, peb cov traction transformers xa cov kev ntseeg siab tsis sib haum xeeb, kev ua haujlwm zoo, thiab kev sib cog lus rau ntiaj teb kev tsheb ciav hlau, metro, thiab hybrid locomotives.
