Yuav ua li cas los daws qhov inverter cua txias E6 kev sib txuas lus txhaum nrog ib tug multimeter
Kev sib txuas lus yuam kev yog dab tsi? Lub hwj chim nyob rau hauv 15S, chav tsev sab hauv tsis tuaj yeem tau txais cov ntaub ntawv xa los ntawm chav tsev sab nraud; los yog thaum lub sijhawm ua haujlwm, chav tsev sab hauv tsis tau txais cov ntaub ntawv raug xa los ntawm chav tsev sab nraum zoov rau 3 feeb sib law liag, tom qab ntawd qhov kev sib txuas lus txhaum E6 yog generated.Lub tuam txhab inverter cua txias txais kev sib txuas lus Circuit Court nyob rau hauv daim ntawv ntawm lub voj tam sim no, uas muaj peev xwm ua kom yooj yim thiab ua qauv kom nkag siab raws li daim duab hauv qab no, yog li yog tias U1 nquag qhib, ces qhov hloov ntawm U4 tuaj yeem ua ke nrog U3, yog li yog tias U3 nquag qhib, qhov hloov ntawm U1 tuaj yeem synchronized nrog qhov ntawd. ntawm U2. U2 synchronization. Tswj lub sijhawm hloov pauv ntawm txhua qhov optocoupler, kev sib txuas lus digital tuaj yeem ua tiav hauv tsev thiab sab nraum zoov.
Yuav ua li cas mus kuaj nrog ib tug multimeter? Qhia ob peb yam kev paub:
Kauj Ruam 1: Tom qab lub zog thiab hloov pauv ntawm chav tsev, siv cov ntaub ntawv AC ntawm lub tshuab hluav taws xob los ntsuas seb lub tsev sab nraud puas muaj hluav taws xob, thiab seb qhov hluav taws xob LN puas zoo li qub? --------- Yog tias tsis muaj hluav taws xob, xyuas lub tshuab sab hauv lossis lub tshuab sab hauv thiab sab nraud txuas cov xov hlau;
Kauj Ruam 2: Voltage ib txwm rau kev sim hauv qab no
Kauj ruam 3: multimeter DC cov ntaub ntawv xeem N-COM voltage, qhov voltage yog 0, kev sib txuas lus fais fab mov Circuit Court yog tsis zoo los yog lub sab nraud maub los lub hwj chim terminals tsis plugged nyob rau hauv, kos lub sab nraud hluav taws xob lub thawv ntawm lub hwj chim mov terminal kev twb kev txuas, paub meej tias qhov hloov pauv;
Kauj ruam 4: multimeter DC cov ntaub ntawv xeem N-COM voltage, qhov voltage yog hais txog 3.7V tas tus nqi, lub ntsiab nti ntawm lub tshuab sab nraud tsis muaj qhov tso zis, xyuas qhov kev sib txuas ntawm txhua qhov hluav taws xob xaim hluav taws xob thiab thauj khoom davhlau ya nyob twg ntawm lub tshuab hluav taws xob sab nraud, paub meej tias qhov hloov pauv;
Kauj ruam 5: Multimeter DC file test N-COM voltage, voltage jumps ntawm 30V-56V, tsis muaj teeb liab tawm tswv yim los ntawm lub tshuab puab, xyuas qhov kev twb kev txuas ntawm txhua lub davhlau ya nyob twg ntawm lub ntsiab board ntawm lub puab lub tshuab, paub meej tias qhov kev hloov;
Kauj Ruam 6: Cov xwm txheej saum toj no yog qhov qub, hloov COM cable cais, saib seb lub tshuab sab hauv thiab sab nraud tuaj yeem sib txuas lus li cas, kom txiav txim siab tawm ntawm txoj kab.
Lus Cim 1: Qee qhov yuam kev motherboards yuav muaj 470K resistor vulcanisation los yog nyiaj migration teeb meem, tom qab lub resistor vulcanisation, tus nqi voltage saum toj no yuav tsim kev hloov.
Lus Cim 2: Raws li qhov xwm txheej ib txwm muaj, cov ntaub ntawv multimeter DC los ntsuas qhov hluav taws xob ntawm N-COM, qhov voltage yuav nyob nruab nrab ntawm 5V-30V-56V tsis tu ncua dhia.
