Kev siv thev naus laus zis ntawm cov khoom siv hluav taws xob induction ntau zaus
Commissioning technology ntawm high-zaus induction cua sov khoom
Commissioning ntawm high-zaus induction cua sov khoom
Ib txwm yuav tsum yog ib txwm ua ntej siv. Txheeb xyuas qhov hloov pauv los ntawm kev ua raws cov theem hauv qab no:
① tsuas yog kaw lub zog siv hluav taws xob ntawm qhov tswj hwm (ceeb toom: tsis txhob kaw qhov hloov pauv huab cua loj ntawm lub Circuit Court loj), nias lub qhov rooj txee
Rov pib khawm (khawm ntsuab), kho lub zog hloov lub pob qhov rooj raws lub sijhawm mus rau qhov siab tshaj plaws, thiab saib nrog ob kab kab oscilloscope seb lub teeb liab tsav ntawm kev tswj tus ncej ntawm txhua IGBT module yog ib txwm muaj (mem tes yog li 50% square wave, mem tes dav
Sab saum toj yog kwv yees li + 15V, kev so yog txog -8V.Qhov nce thiab nqis kab nyob hauv 1 μS, nrog rau caj npab caj npab ob sab nce thiab nqis
Thaj chaw tuag ntawm IGBT rooj vag pulses ntau dua 2 Μs) thiab lees paub tias IGBT tsav teeb liab ntawm tib tus choj caj npab yog isophase (sab saud thiab qis dua yuav tsum tsis pub dhau 0.5 Μs) thiab IGBT tsav teeb liab ntawm sab saud thiab qis dua caj npab caj npab yuav tsum tau thim rov qab.
Kev tshuaj xyuas ntawm pul rectification pulse.Nias lub pob pib, peb SCR lub rooj vag yuav tsum muaj lub plawv dhia nrog qhov siab tshaj 1.8V, qhov dav ntawm lub plawv thiab lub plawv dhia li ntawm 10kHz.
③ ntsuas qhov ntsuas siab.Qhov kaw qhov tseem ceeb hloov pauv huab cua loj (tsis txhob kaw qhov kev tswj hluav taws xob hloov). Tam sim no, pom DC lub ntsuas hluav taws xob ntsuas qhov ntsuas tau maj mam nce mus rau ntau dua 500V, saib seb cov cuab yeej zoo li qub (tsis muaj suab nrov txawv txav, tsis muaj ntxhiab, thiab tsis muaj cov khoom tawg), ua rau sab xis rau 10 feeb, nyob ntawm seb cov cuab yeej siv li ib txwm muaj, lub zog hloov hluav taws xob tuaj yeem tua tau. Tam sim no DC
Lub siab cia li maj mam poob qis rau xoom.
④ cov khoom siv hluav taws xob ua kom sov siab, ua raws cov theem hauv qab no kom pib lub inverter.
Txuas cov dej txias thiab txheeb xyuas seb txhua qhov dej txias txias yog qhov zoo li qub.Kev kho lub moos khawm ntawm lub zog hloov lub pob qhov rooj mus rau qhov tsawg kawg nkaus, kaw lub twj tso kua mis hloov, tswj lub zog hloov pauv thiab hloov lub zog tseem ceeb, Nco tseg thaum DC voltmeter nce mus txog ze li 500V nrog Nias lub pob pib kom ncua 2 vib nas this hauv txoj cai inverter.Qhov rooj yuav tsum muaj cov lus qhia sib xws, maj mam nce lub zog hloov kho lub pob qhov rooj raws lub moos, thiab DC tam sim no thiab lub zog ntsuas cov lus qhia yuav tsum nce tam sim ntawd thiab mus txog tus nqi muab. Tam sim no nyob rau hauv kev ua haujlwm ib txwm.Qhov neeg ua haujlwm tau xa los ntawm cov cuab yeej tsim khoom los kho txhua qhov kev tiv thaiv teeb tsa tus nqi rau qhov xav tau (cov cuab yeej tau hloov kho ua ntej tawm hauv lub Hoobkas, thiab tuaj yeem tsim kho raws li qhov chaw).
Kev piav qhia ntawm ⑤ motherboard potentiometer
P1– tunes qhov nruab nrab tam sim no waveform nuv ze rau sine yoj thiab tawm txog 200 lub kaum ntse ntse.
P2– hloov kho qhov nruab nrab zaus tam sim no cuam tshuam tus nqi loj.
P3 —- FM tam sim no cuam tshuam tus nqi loj.
P8– kho qhov nruab nrab zaus tam sim no tiv thaiv tus nqi loj.
P9– FM kev tiv thaiv tam sim no tus nqi loj.
P10– Cov Lus Sib Tham Zauv.
⑥ Shudown hauv cov theem hauv qab no.
Ua ntej kho lub pob hluav taws xob hloov lub khawm rov qab rau txoj haujlwm yam tsawg kawg nkaus, nyem lub pob rov qab nres, thiab nres lub suab nruab nrab tam sim ntawd.Txais lub hwj chim tseem ceeb hloov, saib DC lub ntsuas hluav taws xob ntsuas hluav taws xob poob mus rau xoom, tom qab ntawd tua lub hwj chim tswj kev hloov thiab lub taub dej
Hloov.
