Cov hlau nplaum tas mus li nrawm- cuam tshuam lub tshuab nqus tsev Circuit Court breaker

Cov hlau nplaum tas mus li nrawm- hloovLub tshuab nqus tsev Circuit Court breakersFeem ntau siv cov hlau nplaum ruaj khov ua haujlwm ruaj khov, uas cov hlau nplaum ruaj khov muab lub zog tuav rau ob qho tib si kaw thiab qhib txoj haujlwm, thiab lub kauj tsuas xav tau luv luv pulse excitation los hloov lub xeev magnetic Circuit Court. Cov qauv no muaj ob peb qhov chaw thiab cov lus teb ceev ceev, tab sis ib zaug cov hlau nplaum tas mus li dhau los ua qhov tsis tuaj yeem demagnetization, lub zog tuav tau txo qis, cuam tshuam ncaj qha hloov kev ntseeg tau.

Ua rau ntawm qhov kev sib tw demagnetization

Qhov kev sib nqus no ua rau muaj kev sib tw tseem ceeb rau peb lub laj thawj tseem ceeb.

Qhov thib ib yog cov nyhuv ntawm qhov tawm tsam magnetic teb. Thaum lub kauj yog hloov mus rau thiab tawm, lub magnetic teb generated los ntawm lub kauj tam sim no yog ib txwm rov qab rau cov hlau nplaum ruaj khov. Ceev hloov yuav tsum luv luv - lub sij hawm siab - tam sim no excitation, ua rau rov qab magnetic teb muaj zog. Yog hais tias lub magnetic Circuit Court tsis zoo tsim thiab lub hauv paus chaw ua hauj lwm ntawm cov hlau nplaum mus tas li nyob rau hauv lub "kink" nyob rau hauv lub demagnetisation nkhaus, irreversible demagnetisation tshwm sim.

Qhov thib ob, cov nyhuv superposition ntawm qhov kub thiab txias.Thaum cov airflow raug cuam tshuam, qhov ncaj qha tam sim no cuam tshuam, ua rau cov cua sov tsim los ntawm cov ntsiab lus sib cuag thiab ntawm cov khoom siv hluav taws xob, yog li nce qhov kub ntawm lub tsev. Raws li qhov kub thiab txias, qhov sib nqus hardness ntawm NdFeB cov hlau nplaum ruaj khov maj mam txo qis; Tsis tas li ntawd, nyob rau ntawm qhov kub thiab txias, lawv lub peev xwm los tiv thaiv cov hlau nplaum rov qab los ua tsis muaj zog, ua rau muaj zog txhua yam poob.

Thib peb, qhov tshwm sim yog loj heev. Tom qab demagnetization, lub bistable tuav quab yuam ua tsis txaus, uas yuav ua rau lub kaw txoj hauj lwm tsis tuav, qhib tsis tiav, los yog txawm tsis ua hauj lwm los yog maloperation.

Yuav daws qhov teeb meem li cas

Txhawm rau daws qhov teeb meem ntawm demagnetisation, nws yog ib qho tsim nyog yuav tsum tau siv cov kev ntsuas ntsig txog cov khoom siv, sib nqus circuits thiab thermal tswj: xaiv cov khoom siv hlau nplaum ruaj khov nrog kev sib zog siab thiab kev ua haujlwm siab rau qhov kub thiab txias; optimize lub magnetic Circuit Court kom qhov opposing magnetic teb tsis tshaj qhov kev nyab xeeb; txwv lub sijhawm tam sim no thiab lub sijhawm ua haujlwm ntawm cov coils; thiab txhim kho cua sov dissipation thiab ntsuas kub. Tsuas yog los ntawm kev tswj cov kev pheej hmoo ntawm demagnetisation tuaj yeem ruaj khov hlau nplaum ceevLub tshuab nqus tsev Circuit Court breakersua tiav ob qho tib si ceev thiab kev ntseeg tau.
