Kev kuaj xyuas lub zog module ntawm lub inverter nrog kev pab los ntawm multimeter
Thaum lub zog module raug kuaj ntawm txoj kev (tawm ntawm daim phiaj), siv lub pointer multimeter R × l thaiv los ntsuas cov khoom sau thiab cov emitters ntawm rau lub diodes ntawm tus choj rectifier thiab rau IGBT raj ntawm cov zis choj nyob rau hauv pem hauv ntej thiab rov qab. cov lus qhia los txiav txim seb lawv puas tau tawg lawm. Txwv tsis pub, Muaj cov ntsiab lus tawg hauv. Siv lub pointer multimeter Bx1k los ntsuas qhov tsis kam ntawm lub rooj vag thiab emitter ntawm rau IGBT raj (tsav lub teeb liab input davhlau ya nyob twg). Lawv yuav tsum yog tib yam. Yog tias muaj qhov sib txawv, qhov tsav Circuit Court lossis IGBT raj puas lawm. Cov kev ntsuas saum toj no tsuas tuaj yeem kuaj pom kev puas tsuaj ntawm IGBT hlab. Tsis muaj qhov qhib Circuit Court puas tuaj yeem kuaj pom. Tom qab lub hwj chim module raug tshem tawm ntawm lub rooj tsav xwm Circuit Court, txhua IGBT raj tuaj yeem ntsuas ntxiv. Cov txheej txheem muaj nyob rau hauv daim duab 1. Lub koob ntawm sab laug qhia tias tsis muaj conduction. Lub koob ntawm sab xis qhia txog kev txuas ntxiv. Yog tias nws tsis tuaj yeem qhib thiab kaw, lub raj puas lawm.
Cov qauv ntawm lub zog inverter module:
Ib feem ntawm cov pob khoom sab hauv ntawm lub tshuab hluav taws xob inverter yog ib-theem lossis peb-theem choj rectifier Circuit Court tsim los ntawm diodes, thiab lwm qhov yog tus choj peb-theem uas muaj rau IGBT raj (insulated gate bipolar transistors) thiab rau damping. diodes siv ua ke. tso zis Circuit Court.
P1 yog lub davhlau ya nyob twg zoo ntawm +300V rectifier tso zis, thiab N1 yog qhov tsis zoo ntawm cov zis rectifier. Ob txhais ceg no yog sab nraud txuas nrog lim electrolytic capacitors, thiab txuas nrog P2 los ntawm kev sib nrig sib inductance coil, thiab Nl txuas nrog N2 los muab lub zog rau cov khoom siv hluav taws xob uas muaj rau IGBT raj.
Cov neeg sau ntawm peb lub IGBT raj nyob rau hauv ib nrab ntawm cov khoom siv hluav taws xob peb-theem txuas nrog rau lub davhlau ya nyob twg zoo ntawm cov khoom siv hluav taws xob. Cov emitters yog U, V, thiab W peb-theem tso zis terminals feem. Lub emitters thiab lub rooj vag ntawm peb lub raj tsim ib nrab ntawm lub peb-theem Choj tsav teeb liab input terminals GU-U, GV-V, GW-W. Cov khoom siv ntawm peb lub IGBT raj ntawm qhov qis dua ib nrab ntawm tus choj peb-theem tso zis txuas nrog U, V, thiab W feem, thiab cov emitters txuas nrog rau qhov tsis zoo ntawm cov khoom siv hluav taws xob. Lub rooj vag ntawm peb lub raj thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob ua rau peb-theem qis dua ib nrab-tus choj tsav teeb liab. Input terminals GX, GY, GZ, thiab B yog lub nres nres terminals.
Tsis muaj braking circuit hauv no module. TH yog cov khoom siv hluav taws xob tiv thaiv hluav taws xob sab hauv. Txawm hais tias tus pins ntawm lwm cov qauv ntawm universal inverter fais fab modules thiab cov cim ntawm lub rooj tsav xwm Circuit Court txawv, nws tsis yooj yim los txheeb xyuas qhov chaw tseem ceeb ntawm tus pin. Cov khoom siv high-end siv cov khoom siv hluav taws xob ntse, uas muaj cov khoom siv hluav taws xob thiab cov braking circuits, thiab muaj ntau tus pins.
Raws li lub npe qhia, zaus converter fais fab module yog lub hwj chim hluav taws xob hluav taws xob hluav taws xob nyob rau hauv zaus converter uas yog potted rau hauv ib lub module raws li ib tug tej yam functional ua ke. Lub zaus converter nws tus kheej yog tsim los ntawm chav tswj thiab lub zog module. Feem ntau, lub inverter fais fab module siv ib qho kev sib koom ua ke ntawm cov vaj tse thiab sab nrauv electrode terminals kom txo tau cov khoom thiab txo cov xov hlau sab hauv.
