Feem ntau faults nyob rau hauv lub auxiliary tswj Circuit Court ntawm lub hwj chim inverter rau kev txij nkawm
Tswj circuits xws li zaus converter tsav circuits, tiv thaiv teeb liab nrhiav thiab ua circuits, mem tes tiam thiab teeb liab ua circuits yog hu ua auxiliary circuits. Tom qab lub auxiliary circuit malfunctions, qhov ua rau ntawm lub malfunction yog kuj complex. Tsuas yog qhov poob ntawm qhov kev pab cuam solidification los yog kev puas tsuaj ntawm kev sib xyaw ua ke (uas tsuas yog tuaj yeem ua haujlwm los ntawm kev hloov lub rooj tswj hwm tag nrho lossis kev sib koom ua ke), lwm yam kev ua txhaum yog yooj yim dua los kuaj xyuas thiab ua haujlwm.
1. Kho qhov tsav Circuit Court txhaum ntawm lub zaus converter
Lub voj voog tsav tsheb yog siv los tsav IGTR ntawm lub inverter, thiab nws kuj yog qhov ua txhaum. Feem ntau, muaj cov cim qhia pom tseeb ntawm kev puas tsuaj, xws li cov cuab yeej (capacitor, resistor, transistor, board luam ntawv, thiab lwm yam) tawg, tawg, tawg, hlau tawg, thiab lwm yam tshwm sim txawv txav, tab sis yuav tsis muaj kev puas tsuaj tag nrho rau lub voj voog tsav tsheb. Cov txheej txheem kev ua haujlwm feem ntau yog raws li daim duab schematic, thiab txhua pab pawg tsav tsheb raug kuaj xyuas, ntsuas, hloov, sib piv, thiab lwm txoj hauv kev los ntawm kauj ruam rov qab;
Los yog sib piv thiab tshuaj xyuas nrog lwm qhov tseeb (tshiab) tsav tsheb, thiab maj mam nrhiav qhov txhaum. Cov kauj ruam daws teeb meem: Ua ntej, ntxuav thiab tshem tawm cov plua plav thiab av ntawm tag nrho lub rooj tsavxwm. Yog tias pom qhov tawg ntawm cov ntawv luam tawm, kho cov hlau; Hloov cov khoom puas tam sim ntawd thaum kuaj pom;
Raws li kev soj ntsuam kev ua tau zoo, cov hau kev xws li kev ntsuas, kev sib piv, thiab kev hloov pauv tau siv los txiav txim siab cov khoom xav tau. Qee cov khoom yuav tsum tau kuaj offline. Tom qab kho lub voj voog tsav tsheb, ib qho oscilloscope yuav tsum tau siv los soj ntsuam cov zis tawm ntawm txhua pab pawg tsav tsheb cov teeb liab. Yog hais tias peb-theem mem tes loj thiab theem tsis sib npaug, tseem muaj qhov txawv txav hauv lub voj voog tsav tsheb (qhov tsis sib xws ntawm cov khoom hloov pauv tuaj yeem ua rau muaj qhov tshwm sim zoo li no), thiab rov kuaj xyuas thiab ua tiav yuav tsum tau ua.
Kev puas tsuaj rau kev tsav tsheb ntawm lub zog siab transistors kuj yog ib qho laj thawj rau kev tiv thaiv overcurrent ua haujlwm. Feem ntau tshwm sim ntawm kev puas tsuaj tsav circuits yog theem poob, tsis sib npaug peb-theem tso zis voltage, thiab tsis sib npaug peb-theem tam sim no.
2. Kho qhov kev puas tsuaj rau lub zaus hloov pauv hloov hluav taws xob
Ib qho kev pom tseeb ntawm kev puas tsuaj hloov hluav taws xob yog tias tsis muaj cov zaub tom qab lub inverter yog powered. Piv txwv li, Fuji G5S zaus converter txais ob-theem hloov fais fab mov, uas yog raws li lub hauv paus ntsiab lus hais tias lub DC voltage ntawm lub ntsiab DC Circuit Court yog txo los ntawm tshaj 500V mus txog 300V, thiab ces los ntawm ib tug-theem hloov voltage. Kev txo qis, lub zog hluav taws xob tso tawm ntau lub zog xws li 5V thiab 24V.
Kev puas tsuaj rau kev hloov cov khoom siv hluav taws xob muaj xws li kev puas tsuaj ntawm cov raj hloov pauv, hluav taws xob hluav taws xob hluav taws xob, kev puas tsuaj rau cov khoom siv hluav taws xob thib ob, kev siv lub tshuab lim dej ntev ntev, ua rau muaj kev hloov pauv hauv cov yam ntxwv ntawm lub capacitor (txo lub peev xwm los yog siab heev tam sim no), txo voltage stability, thiab kev puas tsuaj yooj yim rau kev hloov cov khoom siv hluav taws xob.
Tsis tas li ntawd, ib qho ntawm qhov ua txhaum ntau yog tias qhov hloov pauv zaus tsis tso tawm tom qab tau txais lub zog, thiab feem ntau ntawm cov laj thawj rau qhov tsis zoo no kuj tshwm sim los ntawm kev puas tsuaj rau lub zog hloov hluav taws xob. Lub zog hloov hluav taws xob ntawm MF series zaus converter txais ib qho kev hloov pauv hloov hluav taws xob tswj txoj kev. Lub luv luv Circuit Court nyob rau hauv cov zis theem Circuit Court ntawm lub switching fais fab mov tuaj yeem ua rau muaj kev puas tsuaj rau lub zog hloov hluav taws xob, uas ua rau tsis muaj cov khoom siv ntau zaus.
