(1) Txhaum 1: Kov Demiation
Qhov tshwm sim 1: txoj hauj lwm tau kov los ntawm tus ntiv tes tsis sib phim nrog nas tus xub.
Vim li cas 1: Tom qab kev txhim kho tus tsav tsheb, thaum kho txoj haujlwm, nruab nrab ntawm Bullseye tsis tau chwv ntsug.
Daws 1: recalibrate txoj haujlwm.
Qhov tshwm sim 2: Tus kov nyob rau qee thaj chaw muaj tseeb, thiab kov nyob rau qee thaj chaw yog kev sib ntxub.
Vim li cas 2: Muaj ntau ntau ntawm cov hmoov av lossis cov nplai sau rau ntawm lub suab yoj ib ncig ntawm lub suab kov kov cov duab hluav taws xob.
Kev daws 2: Ntxuav lub kov npo. Them nyiaj tshwj xeeb kom ntxuav lub suab nthwv dej yuav cuam tshuam ntawm plaub sab ntawm lub vijtsam kov. Thaum tu, kaw lub zog hluav taws xob ntawm lub kov tshuaj ntsuam daim npav.
(2) Txhaum 2: Lub vijtsam kov tsis teb rau kov
Qhov tshwm sim: thaum kov lub vijtsam, tus xub nas tsis txav mus thiab tsis hloov nws txoj haujlwm.
Cause: Cov laj thawj rau qhov tshwm sim no muaj raws li hauv qab no:
① Cov hmoov av lossis cov nplai ua rau nthwv dej ncig lub suab
② Lub vijtsam kov tsis tau;
③ Tus Kov Ntsuam Xyuas Card tsis ua;
④ Kov Kov Cov Kab Ntsuas Kab Yeeb Nkab;
⑤ Qhov chaw nres nkoj serial poob;
⑥ Lub operating system ua tsis tiav;
⑦ Kov Kov Screen Tsav Installation Yuam Kev
Cov kev daws teeb meem rau ib qho kev ua yuam kev hauv Siemens Kov ntxaij vab tshaus
Cov kev daws teeb meem rau ib qho kev ua yuam kev hauv Siemens Kov ntxaij vab tshaus
1 Qhov laj thawj yog ib nrab-theem lossis ntau theem inverter tsis muaj. Yog hais tias lub ncov tam sim no ntawm lub hloov raj yog i> 3inrms, inrms yog igbt. Cov xwm txheej no yuav tshwm sim yog tias muaj teeb meem nrog qhov ntsuas uas tam sim no ntawm Inverter, lossis muaj qee yam tsis raug ntawm ib theem ntawm lub rooj vag ntawm inverter. Tom qab qhov kev txhaum no tshwm sim, nws tuaj yeem ua rau muaj kev sib cav luv ntawm cov zis, lossis nws kuj tseem tuaj yeem ua rau lub cev muaj zog los ua kom muaj qhov tsis raug. Feem ntau muaj ob qho xwm txheej thaum txij nkawm:
(1) Cov thawj tswj hwm tsis ua haujlwm thaum lub Siemens Inverter ua cov phiaj xwm dav hlau dav, lub luag haujlwm ntawm cov mem tes tau npaj raws li txoj cai lij choj ua ke. Lub Utgle Wave yog sine yoj, thiab cov cab kuj yoj yog bipolar isosceles wave. Qhov kev sib tshuam ntawm kev sib tshuam yoj thiab cov cab kuj txiav txim siab cov mem tes series ntawm cov inverter Choj Tsim Tawm Theem Hluav Taws Xob. Lub qhov rooj tswj vaj huam sib luag yog qhov pom tau los ntawm kev sib xyaw ua ke ntawm lub tshuab hluav taws xob nrog kev daws teeb meem ntawm 0.00Hz thiab ntau tus mob plawv System. Qhov no tus modulator ua haujlwm asynchronously ntawm ib tug tas li mem tes ntau ntawm 8kHz. Qhov voltage pulgets nws ua rau tig rov qab rau thiab tawm ob lub zog fais fab ntawm tib choj caj npab. Yog tias qhov kev coj ua Circuit Court tsis ua tiav, nws yuav tsis muaj peev xwm tsim cov voltage pulses ib txwm, thiab cov txiag yuav tsum tau hloov thiab kho.
2 Inverter ntaus ntawv ua tsis tiav cov cuab yeej inverter siv hauv Siemens Inverters yog lub GATEFATED GATE BIPOLLAN - igbt. Nws cov yam ntxwv tswj tau cov tswv yim tawm tswv yim loj thiab lub zog tsav tsheb me me thiab nws tsuas tuaj yeem ua haujlwm hauv lub xeev hloov. Tsis tuaj yeem ua haujlwm hauv lub xeev magnified. Nws hloov cov zaus tuaj yeem ncav cuag ntau heev, tab sis nws txoj kev xav tsis zoo yog qhov tsis zoo. Txawm tias tus igbt tivthaiv yog qhov yuam kev tuaj yeem ntsuas nrog ib tug ohmermeter. Cov kauj ruam tshwj xeeb yog raws li hauv qab no:
● Muab cov khoom siv hluav taws xob pov tseg ntawm cov kev hloov pauv zaus;
● Carnonect cov tswj lub cev muaj zog;
● Siv ib tus ohmmeter ntsuas qhov impedance ntawm cov zis davhlau ya nyob twg thiab DC kev sib txuas cov chaw tso tawm A thiab D (saib daim ntawv txuas). Ntsuas txhua qhov kev sim ob zaug los ntawm kev hloov pauv ntawm lub cev ntas ntawm Ohmmeter. Yog tias igbt ntawm cov zaus hloov pauv tau lawm, nws yuav tsum yog: los ntawm U2 mus rau ib qho yog qhov tsis tshua muaj kev tiv thaiv, txwv tsis pub, nws yog qhov tseem ceeb; los ntawm u2 rau d, nws yog siab tiv taus; Txwv tsis pub, nws yog qhov tsis tshua muaj kev tiv thaiv. Tib yam mus rau lwm ntu theem. Thaum lub IGBT raug txiav tawm, nws muaj lub siab tiv taus ntau lub sij hawm, thiab yog tias nws yog luv-ciruited, nws muaj tus nqi tsis kam.

3 Lub zog siv hluav taws xob ua rau tsis ua txhaum yog tshwm sim ua "pulsed resistor", uas txhais tau tias lub zog siv hluav taws xob tiv thaiv tau dhau lawm. Muaj peb qhov laj thawj rau qhov no: tus regenerative braking yog siab dhau, lub zog braking siab dhau lossis lub sijhawm braking luv heev. Lub zog siv hluav taws xob tiv thaiv yog ib feem ntxiv. Txij li thaum thauj khoom ntawm cov khoom siv fiber thiab tshuaj fiber ntau, lub zog hluav taws xob uas muaj kev cuam tshuam nrog cov DC feem ntawm cov zaus hloov pauv mus rau da. Nws lub luag haujlwm tseem ceeb yog txuas lub hwj chim muab hluav taws xob tsis muaj kev txwv ntawm da kab thaum tig mus, tawm lossis chaw thau khoom. Tab sis thaum lub braking tam sim no tshaj qhov ntsuas, lub lag luam yuav cuam tshuam. Feem ntau muaj ob qho xwm txheej:
(1) Lub zog siv tsis kam ua tsis tau. Nyob rau hauv qhov tseeb zaus converter, Mem tes tiv thaiv yog 7.5ω / 30kW. Tom qab siv Inverter tau ntau xyoo, vim muaj kev nquag pib thiab nres ntawm inverter, tus resistor rhaub thiab nws poob qis. Txawm li cas los xij, siemens inverers muaj cov cai nruj ntawm nws tus nqi tiv, tus nqi tiv, uas yuav tsum muaj ntau dua lossis sib npaug 7.5ω. Yog li ntawd, txawm tias qhov tsis kam ntawm lub zog siv hluav taws xob tiv thaiv ntawm cov inverter yog li 7.1ω, qhov kev txhaum saum toj no yuav tshwm sim thiab nws yuav tsis muaj peev xwm pib ib txwm muaj. Tom qab ntawd, kuv hloov mus rau lub siab-zog resistor nrog tus nqi tiv taus ntawm txog 8ω ua ntej kuv yuav tig nws.
(2) igbt tsis ua hauj lwm. Muaj qhov txhaum nyob rau hauv lub igbt ib feem ntawm inverter, uas ua rau cov tswv yim regenerative tam sim no thiab kuj ua rau muaj kev ua tsis tiav ntawm kev siv hluav taws xob tsis txaus ntseeg.
4. Overheating ua txhaum cov lus txhaum yog tso tawm raws li "tshaj dhau" vim tias cov cua sov dissipation kub ntawm lub inverter siab dhau lawm. Cov cua kub ntawm cov zaus hloov pauv feem ntau yog tshwm sim los ntawm cov khoom siv inverter. Cov khoom siv inverter tseem yog qhov tseem ceeb tshaj plaws thiab tsis yooj yim ntawm cov kev hloov pauv, yog li ntsuas kub (NTC) siv ntsuas qhov kub thiab txias Thaum qhov kub tshaj 60 ℃, lub zaus hloov pauv yuav ua ntej lub tswb los ntawm lub teeb liab relay; Thaum nws mus txog 70 ℃, lub zaus hloov pauv yuav cia li nres los tiv thaiv nws tus kheej. Overheating feem ntau yog tshwm sim los ntawm tsib yam mob:
(1) qhov cua sov yog qhov siab. Qee cov lus qhia muaj cov cua sov siab thiab nyob deb dhau ntawm chav tswj hwm. Txhawm rau kom txuag tau cov cables thiab pab txhawb cov haujlwm ntawm lub xaib, lub inverter yuav tsum tau nruab rau ntawm qhov chaw hauv lub rhiav. Nyob rau lub sijhawm no, koj tuaj yeem ntxiv cov cua txias txias rau saum huab cua inlet ntawm zaus hloov pauv kom pab ua kom sov.
(2) Kiv cua tsis ua haujlwm. Cov ntxuam ntawm cov zaus hloov pauv yog 24V DC tsav. Yog tias tus kiv cua cov kabmob yog puas los yog cov kauj yog hlawv thiab cov kiv cua tsis tig, nws yuav ua rau cov twj hloov kom ntau dua.
(3) Cov dab dej kub yog ib qho qias neeg heev. Muaj aluminium tis tshav kub dissipation ntaus ntawv qab ntawm inverter ntawm zaus hloov dua siab tshiab. Tom qab khiav tau ntev, cov sab nraud yuav them nrog hmoov av vim muaj hluav taws xob zoo li qub, cuam tshuam rau cov nyhuv ntawm lub radiator. Yog li ntawd, nws yog qhov yuav tsum tau ntxuav kom huv thiab huv si tsis tu ncua.
(4) thauj khoom ntau dhau. Lub thauj khoom nqa los ntawm zaus hloov pauv yog overloaded rau lub sijhawm ntev, ua rau muaj cua sov. Lub sijhawm no, xyuas hluav taws xob
