Silicon steel sheet cores yog cov khoom tseem ceeb hauv lub zog transformers, motors thiab inductors. Lawv kev ntseeg tau ncaj qha cuam tshuam rau cov cuab yeej ruaj khov thiab kev ua haujlwm zoo. Hauv qab no yog 5 feem ntau tsis ua hauj lwm ua rau silicon steel sheet cores thiab cov tswv yim tiv thaiv kev siv engineering thiab kev saib xyuas.
Core Eddy Tam Sim No Loss Overheating Failure
● Ua Tsis Taus: Eddy currents yog induced nyob rau hauv silicon steel los xij los ntawm alternating magnetic flux. Cov ntsiab lus silicon tsis txaus, cov ntawv thickness ntau dhau los yog cov txheej txheem puas ntsoog kom txo tau qhov tsis zoo tam sim no, ua rau overheating, rwb thaiv tsev melting thiab interlayer luv circuits.
● Kev Tiv Thaiv: Xaiv siab- zoo silicon steel los xij (3.0% - 4.5% silicon, 0.35mm / 0.5mm thickness); tiv thaiv nto rwb thaiv tsev los ntawm khawb; txais cov txheej txheem lamination tsim nyog (qhov sib txawv tsawg dua lossis sib npaug li 0.1mm) txhawm rau txhawm rau eddy tam sim no.
Core Lamination Loosening Failure
● Ua Tsis Taus: Silicon steel core laminations, kho los ntawm bolts los yog rivets, loosen vim lub sij hawm ntev - vibration, kub hloov thiab electromagnetic quab yuam. Loosening tsub kom magnetic tsis kam, ua suab nrov thiab puas rwb thaiv tsev.
● Kev Tiv Thaiv: Optimize kho qauv nrog elastic clamping li; tsis tu ncua fasten xoob bolts; ntxiv damping pads kom txo tau kev vibration.
Core Insulation Deterioration Failure
● Ua Tsis Taus: Core rwb thaiv tsev (interlayer txheej thiab core-rau- coil rwb thaiv tsev) degrades vim qhov hnyav ib puag ncig (siab kub, av noo, corrosion) los yog overvoltage / overcurrent, ua rau luv luv Circuit Court thiab overheating.
● Kev Tiv Thaiv: Siv siab - cov ntaub ntawv rwb thaiv tsev zoo; khaws cov cuab yeej ib puag ncig kom qhuav thiab huv si; nruab overvoltage / overcurrent tiv thaiv thiab kuaj cov rwb thaiv tsev tsis tu ncua.
Core Magnetic Saturation Failure
● Ua Tsis Taus: Core magnetic saturation tshwm sim thaum flux density tshaj 1.5 - 1.7T, tshwm sim los ntawm ntau input voltage, tsis tsim nyog tsim los yog ntev - lub sij hawm overload, ua rau muaj zog hlau poob thiab waveform distortion.
● Kev Tiv Thaiv: Tsim cov tub ntxhais uas tsim nyog tus ntoo khaub lig-sectional cheeb tsam; tswj voltage thiab load kom tsis txhob overload; xaiv silicon steel nplooj ntawv nrog siab saturation flux ceev.
Core Corrosion Failure
● Ua Tsis Taus: Silicon steel sheets corrode nyob rau hauv ya raws, corrosive gas los yog ntsev tsuag, ua puas lub rwb thaiv tsev, txo cov hlau nplaum conductivity thiab mechanical zog, thiab txawm ua rau cov tub ntxhais puas.
● Kev Tiv Thaiv: Siv cov tshuaj tiv thaiv-corrosion txheej rau ntawm qhov chaw tseem ceeb; txhim kho cov cuab yeej sealing; tsis tu ncua tshuaj xyuas thiab tswj, hloov cov nplooj ntawv corroded hnyav.
Xaus
Silicon steel sheet core tsis ua haujlwm feem ntau tshwm sim los ntawm eddy tam sim no overheating, lamination loosening, rwb thaiv tsev deterioration, sib nqus saturation thiab corrosion. Kev tiv thaiv zoo los ntawm kev xaiv cov khoom tsim nyog, kev tsim qauv thiab kev saib xyuas tsis tu ncua ua rau lub neej kev pabcuam tseem ceeb thiab txo qis kev poob haujlwm.
