Yuav ua li cas siv tus mulcalimeter kom paub txog inverter hluav taws xob module
Thaum lub zog hluav taws xob raug sim (disconnected los ntawm lub hwj chim sib tw), tus sau ntawm rau lub cim tso zis tuaj yeem ntsuas tau sai li cas lawv tau tawg. Cov lus 1 thiab Rooj 2 yog cov ntsuas ntsuas ib txwm muaj tseeb, txwv tsis pub muaj muaj sab hauv cov Cheeb Tsam. Ntsuas cov tsis kam (tsav cov ncauj lus tawm tswv yim davhlau ya nyob twg) ntawm lub rooj vag thiab emitter ntawm rau igbt transistors siv tus pointer multimeter bx1k. Yog tias muaj qhov sib txawv, nws qhia tau kev puas tsuaj rau lub tsheb tsav tsheb lossis igbt trantor. Qhov kev ntsuas saum toj no tsuas tuaj yeem ntsuas qhov puas tsuaj ntawm kev puas tsuaj ntawm igbt tub. Tsis muaj kev qhib Circuit Court puas tuaj yeem kuaj pom. Tom qab tshem lub hwj chim module los ntawm Circuit Court Board, txhua daim raj IGBT tuaj yeem ntsuas tau ntxiv siv cov txheej txheem uas pom nyob hauv daim duab 1, qhov twg tus rab koob ntawm sab laug uas tsis tau ua haujlwm. Lub koob nyob rau sab xis qhia tau conductivity. Yog tias nws tsis tuaj yeem muab tua thiab tua, lub raj puas lawm.
Cov qauv ntawm cov zaus converter fais fab qauv:
Sab hauv ntim ntawm zaus converter hluav taws xob module muaj ib-theem lossis peb-theem kev nkag mus rau IGHT tripolar tranterors) thiab rau damping wioden treators) thiab rau damping doden siv ua ke.
P1 yog lub davhlau ya nyob twg yog qhov zoo ntawm +300 V Rectifier tso tawm, thiab N1 yog qhov tsis zoo ntawm lub tswv yim tsim tawm. Ob lub koob muaj chav no yog sab nraud txuas nrog cov tshuaj electrolytic capacitor, thiab tau txuas nrog kev sib nrig sib pab txhawb nqa p2 thiab n1, kom muab cov zis rau igbt.
Cov neeg sau ntawm peb igbt transistors nyob rau sab sauv ib nrab choj ntawm lub chaw tso zis ntawm peb-theem yog U, V, thiab W Peb-theem tsoos tawm. Cov emitters thiab rooj vag ntawm peb lub terminals tsim cov tswv yim terminals gu-u, GW-W rau lub teeb liab tsav ntawm lub sab sauv ntawm peb-theem. Cov neeg sau ntawm peb igbt transistors nyob rau hauv qis dua ib nrab choj ntawm peb-theem tso zis tso zis rau koj, thiab cov emitters tau txuas nrog qhov tsis zoo ntawm lub zog. Lub rooj vag ntawm peb lub chaw tsis zoo thiab cov tsis zoo ntawm lub zog tsim GX, Gy, thiab GZ ntawm peb-theem qis dua ib nrab choj tsav tsheb tsav tsheb, thiab b yog lub cav hluav taws xob.
Tsis muaj lub braking Circuital sab hauv cov qauv no. Th yog cov zis tawm tswv yim tiv thaiv los ntawm tus kws kho mob sab hauv. Txawm hais tias pins thiab cov cim ntawm Circuit Court board ntawm lwm cov qauv ntawm cov hluav taws xob hloov pauv ntau zaus, nws tsis yog qhov nyuaj los txheeb xyuas lub ntsiab tus xov tooj. Cov khoom lag luam xaus siab txais yuav tsum muaj cov kab ke muaj zog thiab cov tsheb ciav hlau nres hauv sab hauv, nrog cov pins sib raug zoo.
Lub zog module ntawm kev hloov pauv zaus, raws li lub npe qhia, hais txog kev sib xyaw ua ke ntawm lub zog hluav taws xob thiab cov hluav taws xob hauv cov haujlwm thiab tom qab ntawd encapsulated rau hauv module. Qhov zaus hloov dua siab nws tus kheej yog tsim ntawm cov chaw tswj thiab lub zog hluav taws xob. Feem ntau, lub zog module ntawm kev hloov kho lub zaus yog tsim los ntawm kev sib txuas ntawm lub plhaub sab nraud thiab sab nraud hluav taws xob kom txo tau tus naj npawb thiab kev siv hluav taws xob sab hauv.
