Kutumiza ukadaulo wazida zotenthetsera pafupipafupi
Kutumiza ukadaulo wa zida zotenthetsera zapamwamba kwambiri
Kukhazikitsa kwa zida zotenthetsera zapamwamba kwambiri
Yachibadwa iyenera kukhala yachibadwa musanagwiritse ntchito.Fufuzani inverter potsatira njira zotsatirazi:
① ingotsekani mphamvu ya gawo lowongolera (chidziwitso: musatseke chosinthira chachikulu chamagetsi chagawo lalikulu), kanikizani chitseko cha nduna
Bokosi loyambira losintha (batani lobiriwira), sinthani ndodo yolumikizira mphamvu mozungulira kupita kumtunda wapamwamba, ndikuwona ndi mizere iwiri ya oscilloscope ngati siginolo yoyendetsa pa pole yolamulira gawo lililonse la IGBT ndiyabwino (zimachitika pafupifupi 50% mafunde ozungulira, kugunda kwa mtima
Pamwamba ndi pafupi + 15V, kupuma ndi pafupifupi 8V. Mizere yokwera ndi yotsika ili mkati mwa 1 μS, mkono wa mlatho uwiri mmwamba ndi pansi.
Dera lakufa la zipata za IGBT ndi zazikulu kuposa 2 Μs) ndikutsimikizira kuti chizindikiro cha IGBT cha mkono womwewo wa mlatho ndi isophase (zolakwa zapamwamba ndi zapansi siziyenera kupitirira 0.5 Μs) ndi chizindikiro cha IGBT chapamwamba ndi chotsika. zida za mlatho ziyenera kusinthidwa.
Kuyang’ana kwa ② rectification pulse.Dinani batani loyambira, zipata zitatu za SCR ziyenera kukhala ndi kugunda kwa matalikidwe akulu kuposa 1.8V, kugunda kwamtima komanso kugunda pafupipafupi pafupifupi 10kHz.
③ kuyesa kukana kukakamiza. Tsekani gawo lalikulu losinthira mpweya (musatseke chosinthira magetsi owongolera).Panthawiyi, onani cholozera cha voltmeter cha DC chikukwera pang’onopang’ono kupitilira 500V, onani ngati zida zake ndizabwinobwino (palibe mawu owopsa, palibe fungo, ndipo palibe kuwonongeka kwa chipangizo), sungani kumanja kwa mphindi 10, malingana ndi zipangizo zomwe zili zachilendo, kusintha kwakukulu kwa mphamvu kumatha kuzimitsidwa.Panthawiyi DC
Kupanikizika kumatsika pang’onopang’ono mpaka ziro.
④ zida zotenthetsera pafupipafupi, tsatirani izi kuti muyambitse inverter.
Lumikizani madzi ozizira ndikuwona ngati njira iliyonse yamadzi ozizira ili yabwino. Sinthani njira yosinthira mphamvu yosinthira mphamvu kuti ikhale yocheperako, tsekani chosinthira mpope, chosinthira mphamvu ndi switch yamagetsi yayikulu, Dziwani pamene DC voltmeter ikukwera pafupifupi 500V ndi kulipira. tsopano mu ntchito yachibadwa.Ogwira ntchito omwe amatumizidwa ndi wopanga zida kuti asinthe mtengo uliwonse wotetezera ku mtengo wofunikira (zidazo zasinthidwa asanachoke ku fakitale, ndipo zikhoza kusinthidwa moyenera malinga ndi malo).
Kufotokozera za ⑤ motherboard potentiometer
P1—— imayitanira mbedza yapakatikati yozungulira yomwe ili pafupi ndi funde la sine ndipo imasiya pafupifupi ngodya 200.
P2– amasintha wapakatikati pafupipafupi panopa kukakumana mtengo kukula.
P3—— Kukula kwamtengo waposachedwa wa FM.
P8– amasintha wapakatikati pafupipafupi panopa chitetezo mtengo kukula.
P9—— Kukula kwa chitetezo chamakono cha FM.
P10—- Frequency Table calibration.
Hud Kutekeseka potsatira izi.
Choyamba sinthani kowuni yosinthira mphamvu motsatana ndi koloko kuti ikhale yocheperako, dinani batani loyimitsa kumbuyo, ndikuyimitsa mawu apakati pafupipafupi. Zimitsani chosinthira magetsi, onani kutsika kwa mita ya DC kufika pa ziro, kenako zimitsani chosinthira magetsi. ndi pompa madzi
Sinthani.
Kufotokozera kwa main control panel chizindikiro chizindikiro nyali ya ⑦ zida zotenthetsera zapamwamba kwambiri:

⑨ Chenjezo: Kusintha kwakukulu kwa mphamvu ikatsekedwa kapena kutembenuzidwa, ndikoletsedwa kuyesa gawo lililonse ndi oscilloscope kapena tebulo, mwinamwake kulephera kudzachitika chifukwa cha kupezeka kwa magawo kunja kwa mapeto a mayesero a chida.
