Multimeter kuaj ntawm inverter fais fab modules
Lub zog module nyob rau hauv txoj kev xeem (tawm ntawm daim phiaj), nrog ib tug pointer multimeter R × l thaiv raws li qhov zoo thiab qhov tsis zoo ntsuas ntawm rau lub diodes ntawm tus choj rectifier thiab cov zis choj ntawm rau IGBT raj ntawm lub collector thiab lub emitter yuav ua tau. txiav txim siab seb puas los yog tsis yog qhov kev puas tsuaj, txwv tsis pub muaj cov khoom tawg hauv. Pointer multimeter Bx1k thaiv los ntsuas rau IGBT raj lub rooj vag thiab emitter tsis kam (tsav lub teeb liab tawm tswv yim) yuav tsum zoo ib yam, muaj qhov sib txawv thaum tsav Circuit Court lossis IGBT raj puas. Cov kev ntsuas saum toj no tsuas tuaj yeem ntsuas qhov IGBT raj tawg puas tsuaj. Tsis tuaj yeem ntsuas qhov qhib-circuit puas. Tom qab tshem tawm lub hwj chim module los ntawm lub rooj tsav xwm Circuit Court, koj tuaj yeem ntsuas ntxiv ntawm txhua IGBT raj, thiab rab koob ntawm sab laug qhia tias nws tsis ua. Lub rooj koob nyob rau sab xis ntawm lub conductive. Yog tias koj tsis tuaj yeem ua rau nws conductive thiab txiav tawm, ces lub raj yuav puas.
TLP251 feem ntau yog siv inverter optocoupler tsav Circuit Court, thaum lub zog module tawg feem ntau spilled hla Circuit Court. Nws sab hauv Circuit Court thiab ntsuas txoj kev qhia nyob rau hauv daim duab 2. Thaum ② ko taw los ntawm 3kΩ resistor thiab 10V fais fab mov yog txiav los yog txuas. Pin ⑥ muaj 0V lossis 9V siab thiab qis voltage hloov.
Cov qauv ntawm lub zog inverter module:
Cov pob khoom sab hauv ntawm lub tshuab hluav taws xob inverter yog ib feem ntawm ib-theem lossis peb-theem choj rectifier Circuit Court tsim los ntawm diodes, thiab ib nrab ntawm peb-theem choj tso tawm hluav taws xob tsim los ntawm rau IGBT raj (insulated gate bipolar transistors) thiab rau damping diodes siv. ua ke nrog lawv.
P1 yog +300V rectified output zoo davhlau ya nyob twg, N1 yog rectified tso zis tsis zoo davhlau ya nyob twg, ob txhais ceg sab nraud lim electrolytic capacitor, thiab los ntawm kev sib nrig sib inductance coil P1 thiab P2 txuas, N l thiab N2 txuas nrog rau rau IGBT raj tsim ntawm cov zis choj fais fab mov.
Peb-theem tso zis choj ntawm lub sab sauv ib nrab ntawm tus choj peb IGBT tube collector yog txuas mus rau qhov zoo kawg ntawm lub hwj chim mov, lub emitter yog U, V, W peb-theem tso zis, peb lub raj emitter thiab lub rooj vag thiab tsim ib tug peb-theem tso zis. theem sab sauv ib nrab ntawm tus choj tsav teeb liab inputs GU-U, GV-V, GW-W. Peb-theem tso zis choj ntawm qhov qis ib nrab ntawm tus choj peb IGBT tube collector tau txuas nrog U, V, W, lub emitter txuas nrog qhov tsis zoo kawg ntawm lub hwj huam mov, peb lub rooj vag raj thiab qhov tsis zoo ntawm lub hwj chim. muab. Lub rooj vag ntawm peb lub raj txuas nrog rau sab tsis zoo ntawm cov khoom siv hluav taws xob, thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob ua rau peb-theem qis dua ib nrab ntawm tus choj tsav teeb liab inputs GX, GY, GZ, thiab B yog lub nres nres nres. .
TH yog cov khoom siv thermistor sab hauv. Lwm cov qauv ntawm lub hom phiaj dav dav inverter fais fab module pins thiab daim ntawv lo rau ntawm lub rooj tsav xwm Circuit Court, txawm tias txawv, tab sis nws tsis yooj yim los txheeb xyuas qhov tseem ceeb ntawm txoj haujlwm ko taw. Cov khoom siv high-end siv cov khoom siv hluav taws xob ntse, kev tsav tsheb hauv Circuit Court thiab braking Circuit Court, tus pin sib raug rau ntau dua.
Inverter fais fab mov module raws li lub npe qhia yog lub inverter fais fab hluav taws xob cov khoom siv hluav taws xob raws li kev sib xyaw ua ke ntawm cov haujlwm thiab tom qab ntawd muab ntim rau hauv ib qho module. Lub inverter nws tus kheej yog tsim los ntawm chav tswj thiab lub zog module. Feem ntau, lub inverter fais fab module yog los ntawm kev siv lub plhaub thiab sab nraud electrode terminals ntawm cov qauv kev sib xyaw ua ke, kom txo tau tus naj npawb ntawm cov khoom thiab txo cov kev sib txuas hauv inductance ntawm lub hom phiaj.
