(1) Cholakwika 1: Kukhudza kupatuka
Chodabwitsa 1: Malo omwe agwidwa ndi chala sichigwirizana ndi muvi wa mbewa.
Chifukwa 1: Pambuyo kukhazikitsa dalaivala, pokonza malo, pakati pa bullseye sichinakhudzidwe vertically.
Yankho 1: Yerekezeraninso malo.
Chodabwitsa 2: Kukhudza m'malo ena ndikolondola, ndipo kukhudza m'malo ena ndikokondera.
Chifukwa 2: Kuchuluka kwa fumbi kapena masikelo amawunjikana pamikwingwirima yowonetsera mafunde mozungulira padziko lapansi, yomwe imakhudza kufalikira kwa mafunde amawu.
Yankho 2: Yeretsani kukhudza chophimba. Samalani kwambiri pakuyeretsa mikwingwirima yowonetsera mafunde mbali zonse zinayi za chophimba chokhudza. Mukayeretsa, chotsani mphamvu ya kirediti kadi yowongolera.
(2) Cholakwika 2: Chojambula chogwira sichimayankha kukhudza
Chodabwitsa: Mukakhudza chinsalu, muvi wa mbewa susuntha ndipo susintha malo ake.
Chifukwa: Zifukwa za chochitika ichi ndi izi:
① Fumbi kapena sikelo yomwe imasonkhanitsidwa pamikwingwirima yowoneka bwino yozungulira pamwamba pa ma acoustic wave touch screen ndizovuta kwambiri, zomwe zimapangitsa kuti chophimba chogwira chilephere kugwira ntchito;
② Chotchinga chokhudza chimalephera;
③ Khadi yoyang'anira skrini yogwira imalephera;
④ Mzere wa chizindikiro cha touchscreen ndi wolakwika;
⑤ Doko la serial likulephera;
⑥ The opaleshoni dongosolo akulephera;
⑦ Vuto loyika dalaivala pa touch screen

1. Mauthenga olakwika a gawo limodzi kapena magawo ambiri amawonetsedwa ngati "inveter u" kapena "inveter v kapena w". Chifukwa chake ndikuti inverter ya gawo limodzi kapena magawo angapo imalephera. Ngati nsonga yapamwamba ya chubu yosinthira ndi i> 3inrms, inrms ndi igbt. Izi zidzachitika ngati pali vuto ndi oveteredwa panopa wa inverter, kapena pali chinachake cholakwika ndi wothandiza magetsi gawo limodzi la chipata cha inverter. Vuto lamtunduwu likachitika, limatha kuyambitsa kuzungulira kwakanthawi kumapeto kwa ma frequency converter, kapena kungayambitsenso injini kunjenjemera kwambiri chifukwa cha zowongolera zolakwika. Nthawi zambiri pamakhala zochitika ziwiri pakukonza:
(1) Kulephera kwa board board Pamene Nokia inverter imapanga kusintha kwa pulse m'lifupi, ntchito yozungulira yamtunduwu imakonzedwa molingana ndi lamulo la sinusoidal. The modulation wave ndi sine wave, ndipo chonyamuliracho ndi bipolar isosceles triangle wave. Malo ophatikizira mafunde osinthira ndi mafunde onyamula amatsimikizira kugunda kwamtundu wamagetsi amagetsi a inverter mlatho. Chitseko chowongolera chitseko chimazindikirika kudzera mu IC (ASIC) yayikulu kwambiri, yomwe imaphatikizapo jenereta yamagetsi yamagetsi yokhala ndi malingaliro ofikira 0.001hz ndi ma frequency apamwamba a 500hz ndi pulse wide modulator yomwe imapanga magawo atatu a sine wave. dongosolo. Izi The modulator imagwira ntchito asynchronously pa pafupipafupi kugunda pafupipafupi 8khz. Mphamvu zamagetsi zomwe imapanga zimayatsa ndikuzimitsa zida ziwiri zosinthira pampando womwewo wa mlatho. Ngati gulu lozungulirali likulephera, silingathe kupanga ma voltage pafupipafupi, ndipo bolodi iyenera kusinthidwa ndikukonzedwa.
2 Kulephera kwa chipangizo cha inverter Chipangizo cha inverter chomwe chimagwiritsidwa ntchito mu Siemens inverters ndi insulated gate bipolar transistor - igbt. makhalidwe ake ulamuliro ndi mkulu athandizira impedance ndi yaing'ono kwambiri chipata panopa, kotero mphamvu galimoto ndi yaing'ono ndipo akhoza ntchito mu dziko kusintha. Sitingagwire ntchito mokulitsidwa. Kusinthasintha kwake kumatha kufika pamwamba kwambiri, koma ntchito yake ya antistatic ndiyosauka. Kaya chigawo cha igbt ndi cholakwika chikhoza kuyezedwa ndi ohmmeter. Njira zenizeni ndi izi:
● Chotsani magetsi osinthira pafupipafupi;
● Chotsani injini yoyendetsedwa;
●Gwiritsani ntchito ohmmeter kuti muyeze kutsekeka kwa zotulutsa zotuluka ndi ma terminals olumikizira a DC a ndi d (onani chithunzi chophatikizidwa). Yesani mayeso aliwonse kawiri posintha polarity ya ohmmeter. Ngati igbt ya frequency converter ilibe, iyenera kukhala: kuchokera ku u2 kupita ku yotsika kukana, apo ayi, ndizovuta kwambiri; kuchokera ku u2 kupita ku d, ndizovuta kwambiri; mwinamwake, ndi kukana otsika. Momwemonso ndi magawo ena. Pamene igbt imachotsedwa, imakhala ndi mtengo wotsutsa kwambiri nthawi zonse ziwiri, ndipo ngati ili yochepa, imakhala ndi mtengo wotsika.

3 Kulephera koletsa kugwiritsa ntchito mphamvu Mauthenga olakwika amawonetsedwa ngati "pulsed resistor", kutanthauza kuti choletsa kugwiritsa ntchito mphamvu chadzaza. Pali zifukwa zitatu izi: mphamvu ya braking regenerative ndi yokwera kwambiri, mphamvu ya braking ndiyokwera kwambiri kapena nthawi ya braking ndi yochepa kwambiri. Mphamvu yotsutsa mphamvu ndi gawo lowonjezera. Popeza katundu wa zida za nsalu ndi mankhwala opangidwa ndi fiber ndi katundu wochuluka kwambiri, chubu chosinthira mphamvu kwambiri ndi mphamvu yogwiritsira ntchito mphamvu zimagwirizanitsidwa mofanana ndi gawo la DC la ma frequency converter ku DA wiring. Ntchito yake yayikulu ndikulumikiza magetsi Mwamphamvu amachepetsa kuchulukirachulukira pa mzere wa da poyatsa, kuzimitsa kapena kutsitsa. Koma pamene braking current iposa mlingo, ntchitoyo idzasokonezedwa. Nthawi zambiri pamakhala zochitika ziwiri:
(1) Kulephera kwa mphamvu yamagetsi. Mu zenizeni pafupipafupi Converter, kugunda resistor ndi 7.5ω/30kw. Pambuyo pakugwiritsa ntchito inverter kwa zaka zingapo, chifukwa choyambira pafupipafupi komanso kuyimitsidwa kwa inverter, chopingacho chimatenthedwa ndipo kukana kwake kudachepa. Komabe, ma inverters a Siemens ali ndi zofunikira zolimba pa mtengo wake wokana, womwe umayenera kukhala wokulirapo kapena wofanana ndi 7.5ω. Choncho, ngakhale kukana kwa mphamvu yotsutsa mphamvu ya inverter iyi ndi pafupifupi 7.1ω, cholakwika pamwambapa chidzachitika ndipo sichidzatha kuyamba bwinobwino. Pambuyo pake, ndinasinthira ku chotsutsa champhamvu kwambiri chokhala ndi mtengo wotsutsa pafupifupi 8ω ndisanayambe kuyatsa.
(2) kulephera kwa igbt. Pali vuto mu gawo la igbt la inverter, lomwe limayambitsa kubweza kwambiri pakalipano komanso kumayambitsa kulephera kwamphamvu kwa choletsa kugwiritsa ntchito mphamvu.
4. Kuwotcha kwachangu Uthenga wolakwika ukuwonetsedwa ngati "kutentha kwapamwamba" chifukwa kutentha kwa kutentha kwa inverter ndikokwera kwambiri. Kutentha kwa ma frequency converter makamaka kumayambitsidwa ndi chipangizo cha inverter. Chipangizo cha inverter ndichofunikanso kwambiri komanso chosalimba cha osinthira pafupipafupi, kotero sensor ya kutentha (ntc) yomwe imagwiritsidwa ntchito kuyeza kutentha imayikidwanso kumtunda kwa chipangizo cha inverter. Kutentha kukakhala kopitilira 60 ℃, chosinthira pafupipafupi chimakhala ndi ma alarm kudzera pamawu otumizira; ikafika 70 ℃, chosinthira pafupipafupi chimangoyima kuti chiteteze. Kutentha kwambiri kumachitika chifukwa cha zinthu zisanu:
(1) Kutentha kozungulira kumakhala kwakukulu. Malo ena ogwirira ntchito amakhala ndi kutentha kwakukulu kozungulira ndipo ali kutali kwambiri ndi chipinda chowongolera. Kuti mupulumutse zingwe ndikuwongolera ntchito pamalowo, inverter iyenera kukhazikitsidwa pamalo ochitira msonkhano. Panthawiyi, mutha kuwonjezera njira yoziziritsira mpweya ku cholowetsa mpweya wa chosinthira pafupipafupi kuti muchepetse kutentha.
(2) Kulephera kwa mafani. Chowotcha chotulutsa ma frequency converter ndi 24v DC mota. Ngati fani yawonongeka kapena koyilo yatenthedwa ndipo fani sichizungulira, izi zimapangitsa kuti chosinthira pafupipafupi chiwotche.
(3) Danga lakuya ladetsedwa kwambiri. Pali aluminium fin heat dissipation chipangizo kumbuyo kwa inverter ya frequency converter. Pambuyo pothamanga kwa nthawi yayitali, kunja kudzakutidwa ndi fumbi chifukwa cha magetsi osasunthika, zomwe zimakhudza kwambiri mphamvu ya radiator. Choncho, m'pofunika kuyeretsa ndi kuyeretsa nthawi zonse.
(4) Katundu wambiri. Katundu wonyamula ma frequency converter amalemedwa kwa nthawi yayitali, kuchititsa kutentha. Panthawiyi, fufuzani magetsi
