Muaj pes tsawg txoj kev sim rau PCB electromagnetic Cheebtsam?

Kev ntsuam xyuas PCB electromagnetic Cheebtsam yog ib feem tseem ceeb ntawm kev kuaj PCB. Yog li, pes tsawg txoj kev sim muaj rau PCB electromagnetic Cheebtsam?

1.Ordinary coil xeem

Rau kev sim coil, tus choj digital tuaj yeem siv los ntsuas qhov inductance hauv online. Vim tias qhov ua haujlwm zaus ntawm lubinductor kaujfeem ntau tsis qis, qhov inductance tuaj yeem kuaj tau ntawm qhov zaus siab tshaj 10kHz.

2. Transformer coil test

Los ntawm kev ntsuam xyuas qhov inductance D tus nqi ntawm transformer lub ntsiab kauj, peb tuaj yeem txiav txim siab seb qhovtransformerNws muaj ib tug luv luv Circuit Court. Txoj kev tshwj xeeb yog: teeb tsa tus choj digital rau 0.3V lossis qis dua, 10kHz lossis siab dua, thiab ntsuas tus nqi D ntawm lub ntsiab coil inductance. Yog tias tus nqi D ntau dua 0.1, nws raug txiav txim tias lub tshuab hloov pauv puas thiab siv tsis tau.

3. Tshawb xyuas cov cuab yeej Hall

Hall sensors muaj nyob rau hauv ib lub hwj chim mov thiab dual fais fab mov, raws li zoo raws li tam sim no cov zis hom thiab voltage tso zis hom. Ib lub zog hluav taws xob ib leeg tsis pom tam sim no, thiab cov teeb liab tso zis feem ntau yog 1/2 ntawm ib qho hluav taws xob. Yog tias qhov tam sim no yog 0, lub teeb liab tso zis deviates ntau los ntawm tus nqi nruab nrab. Lub sensor tseem tuaj yeem raug kuaj ntau los txiav txim siab seb Hall sensor puas puas lawm. Hall sensor nrog dual fais fab mov outputs 0 voltage thaum nws senses 0 tam sim no; Thaum nws hnov ​​lwm yam tsis yog 0 tam sim no, qhov zoo, qhov tsis zoo thiab qhov loj ntawm cov zis hluav taws xob hloov pauv nrog qhov loj thiab cov kev taw qhia ntawm qhov induced tam sim no.

4. Kev ntsuam xyuas ntawm cov relays

Feem ntau ua txhaum ntawm relays muaj xws li coil disconnection, tiv tauj tsis kaw, siab tiv thaiv, thiab hlawv cov neeg. Txoj hauv kev zoo tshaj plaws los ntsuas seb tus relay puas yog qhov qub yog los txhawb lub zog relay, siv qhov ntsuas hluav taws xob rau lub kauj, thiab tom qab ntawd sim qhov kev sib cuag txuas ntxiv.
