Fais fab mov: DC thiab AC

Qhov voltage ntawm lub fuse yog dab tsi?
Qhov hluav taws xob ntawm lub fuse tuaj yeem qhia tau hais tias: lub fuse tuaj yeem tawg lub arc generated los ntawm qhov voltage. Raws li cov cuab yeej tiv thaiv hauv Circuit Court, thaum muaj kev txhaum tshwm sim hauv Circuit Court, fuse ua haujlwm tau muab faib ua ob txoj haujlwm: "melting" ntxiv rau "tawg". Cov txheej txheem ntawm "melting" muaj feem xyuam rau qhov tam sim no, thiab cov txheej txheem ntawm "tawg" muaj feem xyuam rau qhov kev sib txuas ntawm qhov hluav taws xob.

Qhov sib txawv ntawm fuse voltage
Lub fuse voltage yog txawv ntawm alternating tam sim no thiab ncaj qha tam sim no. Hauv cov tsheb hluav taws xob ntshiab, nws yog qhov hluav taws xob ncaj qha tam sim no, vim hais tias qhov inductance hauv lub voj yuav tsim qhov induced voltage nyob rau lub sijhawm thaum lub fuse tawg, thiab tib lub sijhawm, qhov cuam tshuam ntawm inductance nyob rau hauv lub voj ntawm qhov voltage arc extinguishing. yuav tsum tau txiav txim siab.Qhov siab tshaj plaws tus nqi hluav taws xob uas lub fuse tuaj yeem tiv taus yuav tsum ntau dua li tus nqi hluav taws xob hauv qhov system. Nyob rau tib lub sijhawm, muaj qhov sib txawv tseem ceeb ntawm AC thiab DC fuses hauv kev rhuav tshem cov arc;
Txawm li cas los xij, tsis muaj xoom-hloov taw tes nyob rau hauv ib qho waveform ntawm DC lub zog. Thaum tawg DC luv luv-circuit tam sim no, lub arc raug yuam kom tua los ntawm vaporization sai ntawm fuse thiab diffusion, adsorption thiab txias ntawm quartz xuab zeb, yog li nws yog qhov nyuaj dua li kev tawg AC arc.
