Lub axial thiab radial zog ntawm transformer windings yog qhov tseem ceeb kom ntseeg tau cov tshuab hluav taws xob ruaj khov nyob rau hauvLuv -} Circuit Court tej yamthiabThermal nthuav davThaum lub sijhawm ua haujlwm. Hauv qab no yog cov txheej txheem tseem ceeb tau siv hauv kev tsim qauv thiab kev ntsuas ntawm cov zog no:
1. Radial Dag Cov Qauv
Radial Txuj Kev Uasab nraud lossis sab hauvRaws txoj kev winding ncig, sim nthuav tawm lossis compress cua thaum lub sijhawm luv - circuits. Yog tias lub zog radial yog tsis txaus, nws tuaj yeem ua rauleegntawm cov windings. Cov qauv tsim muaj xws li:
Withstand luv - Circuit Court radial rog
Cov rog raug suav raws li lub suab luv luv - Circuit Court tam sim no.
Radial quab yuam Frf_RF yog ntawm kev sib nqus teb lub zog thiab tam sim no:
QRSI2 × € × nf_r \\ prestro i ^ 2 \\ sij hawm \\ mu_0 \\ Time αi2 × n
Qhov twg iii tam sim no, μ0 \\ mu_0μ0 yog lub permeability ntawm chaw pub dawb, thiab NNN yog tus naj npawb ntawm lem.
Kev ntsuas kev nyuaj siab thiab kev ntsuas kev nyuaj siab
Cov windings yuav tsum muaj kev ntxhov siab compressive (hoop kev nyuaj siab) nyob rau hauv luv {{0} {circuit.
Cov khoom siv tawm lub zog, cov tub ntxhais hluas cov modulus, thiab poisson tus piv txwv ntawm tus neeg xyuas pib (piv txwv li, tooj liab lossis txhuas).
Lub Tog Hluav Taws Xob thiab Txhawb Cov Rings
Cov khoom siv rwb thaiv tsev yog siv los tiv thaiv kev deformation los ntawm kev faib tawm ntawm cov windings.
Them Nyiaj Kho Mob Thermal
Cov ntaub ntawv yuav tsum tau tshaj cov nqi hluav taws xob nthuav dav los tiv thaiv radial chaw tsis zoo vim yog cov cua sov tsim.
2. Axis Dag Cov Qauv
Axial yuam kev ua yeeb yamraws qhov ntevntawm winding, ua rau nws siv rau cav kom lossis ncab. Tsis muaj zog muaj zog muaj peev xwm ua rauTelescoping deformationlossis txav ntawm cov khaubncaws sab nraud. Cov hauv qab no tau txiav txim siab:
Luv -} Circuit axial rog
Cov rog tau suav rau kev txhaum rau cov neeg txhaum, uas tsim kom muaj ob qho tib si txaus nyiam thiab tsis pom zoo ntawm cov winding ntawm txheej.
Lub zog faf_afa yog sib npaug rau cov khoom ntawm cov txhaum tam sim no thiab sib nqus flux ntom:
Faeesi × bf_a \\ prestro i \\ sij hawm bfa αi × b
Ua ntej - compression ntawm windings
Windings yog ua ntej - compressed thaum sib dhos kom txo qis kev txav mus kom txo kev txav mus los thaum ua haujlwm. Qhov no kuj yuav txo qhov kev pheej hmoo ntawm txheej sib cais.
Clamping Siab
Txaus siab clamping siab yog tswj kom tiv thaiv Axial chaw teeb tsa thaum lub sijhawm luv - circuits. Clamping Systems nrog ntsuas hluav taws xob ua kom meej meej kom muaj kev faib tawm.
Mechanical Zog Ntawm Rwb Thaiv Tsev Thiab Pab Txhawb Cov Qauv
Cov ntaub ntawv insulating siv ntawm cov khaubncaws sab nraud povtseg (piv txwv li, nias lossis Nomex) yuav tsum muaj lub zog compressive kom tiv taus Axial yuam.
3. Cov Khoom Siv Khoom Siv rau Lub Zog Tsim
Tooj liab thiab txhuas: Yuav tsum muaj lub zog siab tensile thiab tsis txaus ntseeg nyob rau hauv cov rog siab.
Presseboard rwb thaiv tsev: Muab kev txhawb nqa kev siv tshuab thiab rwb thaiv tsev, muaj lub zog compressive.
Joke thiab tub ntxhais clamps: Siv los tiv thaiv axial txav ntawm windings windings, tsim kom tau txais kev ntxhov siab txhua yam.
4. Cov qauv kev lag luam thiab cov npoo kev nyab xeeb
IEC 60076-5: Qhia meej luv -} Circuit Court Kev xav tau rau cov hluav taws xob hluav taws xob.
IEEE C57.12.00: Muab cov lus qhia rau luv- Circuit Circuit SCRESS of Distrimate Transformers.
Kev Nyab Xeeb Kev Nyab Xeeb: Ib qho npoo (feem ntau yog 1.1 rau 1.5) yog thov tshaj kev siv kev ntxhov siab rau tus account rau kev tsis paub tseeb.
Cov qauv no ua kom cov cua yuav tiv thaiv ob qho tib siNeeg kho tshuab thiab cua kub ntxhov siabTshaj lub transformer lub neej ua haujlwm, tshwj xeeb tshaj yog raws li cov kev txhaum.
