02 Kev tsim khoom
2.1 Core
Cov tub ntxhais yog ua los ntawm cov permeable heev, txias -rolled silicon steel laminations. Nws cov qauv yog peb hom - ceg, nrog rau peb -theem windings raug mob nyob ib ncig ntawm peb ntsug core ob txhais ceg feem. Qhov kev tsim no muab qhov tsawg - txoj kev tsis txaus siab rau cov hlau nplaum sib nqus, ua kom muaj txiaj ntsig zoo ntawm peb -theem magnetic teb. Cov txheej txheem lamination thiab siab - cov ntaub ntawv zoo yog tsim los txo qis eddy tam sim no thiab hysteresis poob, yog li txhim kho lub transformer lub zog efficiency thiab kev ua hauj lwm.
2.2 Cua txias
Cov windings ntawm no transformer siv txhuas rau ob qho tib si qis-voltage foil thiab high-voltage hlau. Lub LV winding siv cov ntawv txhuas dav dav, muab lub zog luv luv - lub zog hluav taws xob thiab ua kom txias. Lub HV winding siv insulated aluminium hlau, qhov txhab kom ua tiav qhov ntsuas qhov tsim nyog. Qhov no tag nrho - aluminium tsim muab tus nqi- siv tau thiab txhim khu kev qha.
2.3 Tank
Lub tank yog lub kaw ntom nti, corrugated steel enclosure uas muaj cov tub ntxhais thiab windings thaum muaj cov roj insulating. Nws cov phab ntsa corrugated muab thaj chaw loj rau cov cua sov kom zoo rau cov huab cua puag ncig, ua kom muaj kev ua haujlwm ruaj khov. Tsim los rau kev ua haujlwm ntev thiab kev saib xyuas tsawg, nws muaj kev tiv thaiv tag nrho rau cov khoom siv sab hauv.
2.4 Kev sib dhos zaum kawg
Lub rooj sib txoos zaum kawg ua ke nrog cov tub ntxhais -coil sib dhos, rau hauv lub tank kaw corrugated steel thiab ntim nrog cov roj insulating. Cov khoom tseem ceeb xws li HV / LV bushings, lub twj tso kua mis siab, surge arrester thiab lwm yam accessories yog mounted externally. Qhov no tsim kom muaj tus kheej tag nrho-muaj, muaj zog, thiab kev saib xyuas- chav tsev phooj ywg, npaj rau kev teeb tsa thiab daim phiaj sib txuas.
03 Kev Xeem
Peb -theem pad mounted transformer (qauv: 1000KVA 22.86Grdy/13.2-0.208/0.12kV) tau sim rau lub Kaum Hlis 19, 2024 (ambient kub 34℃, txheeb ze humidity 73%) IE raws li cov qauv xws li C57.12.00-2021 thiab IEEE C57.12.34-2022. Cov kev ntsuam xyuas suav nrog kev ntsuas kev ntsuas cua (qhov siab tshaj qhov tsis sib npaug 5.51%), qhov ntsuas qhov sib piv (lub ntsiab kais sib txawv -0.03 ~ 0.00%), theem kev sib txheeb (qhov tshwm sim YNyn0), tsis muaj kev thauj khoom poob thiab kev sim tam sim no (1016W ntawm 20 degree, 0.15% tam sim no), load poob, impedance 78℃thiab efficiency load (W) 6.09% impedance, 99.45% efficiency), thov voltage test (10kV rau LV rau hauv av, 60s tsis tawg), induced voltage withstand test (45.72kV induced ntawm HV, 150Hz rau 48s tsis muaj kev puas tsuaj), siab leak test (20kPa rau 12h tsis muaj to / 5V kev puas tsuaj), rwb thaiv tsev. av), thiab roj dielectric xeem (56.3kV dielectric zog, 9.5mg / kg ya raws), tag nrho cov uas dhau.
