Cov tub ntxhais toroidal rau cov qhov tso zis inverter xaus kaum ib los

(1) thov siv fais faib mov zaus converter, deb ntawm cov loj loj zog dc arc vuam tshuab, vuam machineand #39; s grounding tus kheej yuav tsum zoo. (2) thiab zaus converter hauv lub fais tib txee yuav tsum xaiv zoo contactor contactor, muaj zoo xaiv cov khoom arcing uas zoo nyhuv, thiab kom muaj tej yam nyob deb li cas nrog converter zaus. (3) lub hwj huam mov voltage kom tsis txhob hloov, ruaj khov. (4) yuav tau inverter grounding kawg kom thwj. (5) kab cais los ntawm fais taug kev ntawm kab, canand #39; t muab tso rau hauv ib yam dab. Siv shielding hlau kab, raws li tau hnav tus yeeb nkab kab, hlau txuas nrog zoo hose. (6) nrog lub tswv yim converter zaus yeej thiab tso zis ntau kawg, mus tib seem thiab nyob ib ncig ntawm 3-4 laps, pab suppress harmonic kev txiav txim siab. Yog ntxiv txhim khu anti-jamming nyhuv, mounted yuav tsum rau reactor, lim, etc. (7) tus inverter tswj kab los teeb liab analog nrog lub vas. RS485 kev sib txuas lus chaw nres nkoj (8) no txuas nrog lub PC siv kev rho tawm photoelectric. (9) yuav pab kom cov cab kuj zaus. (10) hnub cuam ntsuas khoom rau shield, shielding enclosure grounding, muaj cai nyob rau hauv qhov kev ntsuas ntawm cov hwjchim rau hauv lub davhlau ya nyob twg nrog lub vas, lub teeb liab hlau sab lim capacitance. (11) rau kab kawg thiab inductance, etc. Tooj hauv PCB Circuit Court tsim kom xaiv qhov muaj cai sib nqus hlaws dai, kev ntawm yuav tsum them kom cov nram qab no: 1, donand #39; t tau lub teeb liab zaus ntau yog npaum li cas; 2, nws yog ib qhov suab nrov nrov ntawd; 3, pes suab attenuation; 4, yog dab tsi mob tej (kub, dc voltage, tus yam ntxwv ua tau); Npaum li cas yog 5, Circuit Court thiab load impedance; 6 yog muaj tej chaw mus tso rau ntawm lub Rooj Tswjhwm Saib PCB, hlaws dai sib nqus; Vas thiab tus thawj peb los tsom xam cov khw muab cov impedance ntawm cov zaus nkhaus yuav tau siv. Tseem ceeb heev, peb curves hauv lub impedance nkhaus namely cov kuj, inductance thiab cov impedance nrho. Lub impedance tag nrho los ntawm ibce ZR22 PI (2 +): = ibce. Nyob rau hauv cov vam cia ntawd los ntawm qhov nkhaus, xaiv ntau lub impedance thiab attenuation cov suab nrov zaus ntau yam nyob rau hauv qhov tsawg zaus thiab dc teeb liab attenuation xyaum kom deb li deb tau me me sib nqus hlaws dai. Khis sib nqus cov hlaws dai nyob ntev li ntawm dc voltage, impedance cov yam ntxwv yuav muaj cuam tshuam, ntxiv mus, yog tus ua hauj lwm ntsuas ntshav, los yog lwm magnetic teb tseem hwv loj, lub impedance ntawm lub hlaws dai sib nqus yuav muaj cuam tshuam los ntawm qhov ua phem. Siv hauv sib nqus nplhaib thiab nti inductor vim li cas: siv cov hlaws dai hauv sib nqus los yog nti inductance loj nta kuj nyob rau hauv daim ntawv thov. Koj yuav tau siv cov nti inductor nyob hauv lub resonant Circuit Court. Plav tshem tawm suab nrov EMI, koj donand #39; t tau siv nti sib nqus hlaws yog tus xaiv zoo. Hlaws dai sib nqus hauv thiab nti inductance kev siv: khis inductors, mloog xov tooj cua zaus (RF) thiab sib wireless, khoom siv tshuab, radar ntes, tsheb, ntawm tes, pagers, lub khoom, PDAs (personal digital pab), wireless tswj chaw taws teeb thiab voltage uas tsis muaj hwj huam muab module, thiab lwm yam lus.
