Resistance nce yog ib qho tshwm sim tshwm sim nyob rau hauv nruab nrab zaus inverter chaw vuam tshuab.Cov kab lus no yog tsom rau kev txheeb xyuas cov yam ntxwv ntawm kev tiv thaiv nce thiab nws qhov cuam tshuam hauv qhov chaw vuam ua haujlwm.
Cua sov nyhuv:
Ib qho ntawm cov ntsiab lus tseem ceeb uas ua rau muaj kev tiv thaiv nce ntxiv yog cov cua sov thaum lub sij hawm qhov chaw vuam.Thaum lub siab tam sim no dhau los ntawm qhov chaw ua haujlwm, cov cua sov yog tsim los ntawm hluav taws xob tsis kam.Qhov cua sov no ua rau lub workpiece qhov kub thiab txias, ua rau muaj kev nce hauv nws qhov kev tiv thaiv.
Khoom siv:
Qhov kev tiv thaiv nce kuj tuaj yeem cuam tshuam los ntawm cov khoom siv ntawm lub workpiece.Qee cov ntaub ntawv nthuav tawm ntau dua ntawm kev tiv thaiv piv rau lwm tus vim lawv cov khoom siv hluav taws xob thiab cov khoom siv thermal.Piv txwv li, cov khoom siv nrog qis conductivity los yog siab dua thermal expansion coefficients yuav ua rau muaj kev tiv thaiv ntau dua.
Tiv tauj Resistance:
Lwm qhov tseem ceeb uas tuaj yeem ua rau muaj kev tiv thaiv nce ntxiv yog kev sib cuag ntawm cov electrodes thiab cov khoom ua haujlwm.Kev sib cuag electrode tsis zoo los yog qhov chaw paug tuaj yeem ua rau muaj kev tiv thaiv ntau dua, ua rau muaj kev tiv thaiv tag nrho thaum vuam.
Electrode Hnav:
Nyob rau tib lub sijhawm, cov electrodes hauv cov tshuab vuam tshuab tuaj yeem raug hnav thiab degradation.Raws li qhov chaw electrode deteriorate, lawv qhov chaw sib cuag nrog lub workpiece txo qis, ua rau muaj kev tiv thaiv thiab kev tiv thaiv tag nrho thaum vuam.
Oxidation thiab Contamination:
Lub xub ntiag ntawm oxidation los yog paug ntawm lub workpiece nto tuaj yeem ua rau muaj kev tiv thaiv nce ntxiv.Oxidized los yog cov kab mob paug muaj hluav taws xob ntau dua, cuam tshuam rau qhov ntws ntawm tam sim no thiab ua rau muaj kev nce ntxiv hauv kev tiv thaiv thaum vuam.
Resistance nce yog ib tug yam ntxwv tshwm sim nyob rau hauv nruab nrab zaus inverter qhov chaw vuam tshuab, feem ntau tshwm sim los ntawm cov cua kub nyhuv, cov khoom siv, kev tiv thaiv, electrode hnav, thiab nto oxidation los yog paug.Kev nkag siab txog cov yam ntxwv no yog qhov tseem ceeb rau kev txhim kho qhov chaw vuam txheej txheem thiab ua kom ntseeg tau zoo thiab txhim khu kev qha welds.Los ntawm kev saib xyuas thiab hais txog cov yam tseem ceeb uas ua rau muaj kev tiv thaiv nce ntxiv, cov neeg ua haujlwm tuaj yeem tswj hwm qhov kev xav tau ntawm vuam thiab ua tiav cov vuam zoo hauv lawv daim ntawv thov.
