02 Kev tsim khoom
2.1 Core
Cov tub ntxhais yog tsim los ntawm qib siab - zoo lis- qhia txog silicon steel ntawv. Cov khoom siv tshwj xeeb no yog laminated meticulously thiab lub qhov txhab kom txo cov tub ntxhais poob thiab ua kom muaj kev sib nqus zoo. Nws cov nplej -cov qauv taw qhia txo qis hysteresis thiab eddy tam sim no poob, kom ntseeg tau zoo heev sib nqus permeability thiab tsis muaj -load fais fab noj. Cov tub ntxhais kawm tiav engineering pab txhawb rau lub transformer ua haujlwm siab, tsis muaj suab nrov, thiab tag nrho lub zog-txuag kev ua haujlwm.
2.2 Cua txias
Cov coils siv high-purity aluminium conductors, nqus tsev vacuum-pressure impregnated (VPI) nrog siab - qib insulating kua roj vanish. Cov txheej txheem no tsim cov khoom ruaj khov, noo noo- tiv thaiv rwb thaiv tsev uas ua kom zoo thermal stability, txhua yam muaj zog, thiab txhim khu kev qha ua haujlwm raws li qhov xav tau.
2.3 Kev sib dhos zaum kawg
Qhov kawg sib dhos ntawm VPI qhuav- hom transformer integrates impregnated core thiab coils mus rau hauv ib tug robust mechanical qauv, ruaj ntseg mounted nrog vibration-resistant fasteners. Kev sib txuas hluav taws xob yog qhov tseeb- txiav nrog siab- lub zog txuas, thaum cov kiv cua txias thiab cov ntaub thaiv npog tau teeb tsa kom ntseeg tau tias kev tswj xyuas thermal zoo thiab kev nyab xeeb ntawm kev ua haujlwm.
03 Kev Xeem
Kev ntsuam xyuas ntawm VPI qhuav hom transformer (315kVA-11/0.55kV) ntawm 2024/12/5, raws li IEC cov qauv, npog winding kuj (tsim nyog tsis sib npaug), voltage ratio/theem (me me sib txawv, Dyn11), luv-circuit/no-load parameters, tsis tshua muaj voltage (tsis muaj qhov sib npaug) thiab tsis sib npaug 10 npC). Tag nrho cov txiaj ntsig tau raws li qhov xav tau, tsim nyog.
