(1) Ikosa 1: Gukoraho
Fenomenon 1: Umwanya wakozweho urutoki ntabwo uhuye numwambi wimbeba.
Impamvu ya 1: Nyuma yo gushiraho umushoferi, mugihe ukosora ikibanza, hagati ya bullseye ntiyakozweho neza.
Igisubizo 1: Ongera uhindure umwanya.
Fenomenon 2: Gukoraho mubice bimwe nukuri, kandi gukoraho mubice bimwe bibogamye.
Impamvu ya 2: Umubare munini wumukungugu cyangwa umunzani urundarunda kumurongo wamajwi yerekana amajwi azenguruka hejuru ya ecran ya acoustic wave touch, bigira ingaruka mukwirakwiza kwijwi ryamajwi.
Igisubizo 2: Sukura ecran yo gukoraho. Witondere cyane gusukura imirongo yerekana amajwi kumpande enye za ecran ya ecran. Mugihe cyo gukora isuku, hagarika amashanyarazi yikarita yo kugenzura ikoraho.
(2) Ikosa 2: Mugukoraho ecran ntabwo isubiza gukoraho
Fenomenon: Iyo ukora kuri ecran, umwambi wimbeba ntigenda kandi ntuhindura umwanya wacyo.

Ibisubizo kubibazo bisanzwe muri Siemens ikora kuri ecran
Ibisubizo kubibazo bisanzwe muri Siemens ikora kuri ecran
1. Amakuru yamakosa yicyiciro kimwe cyangwa ibyiciro byinshi byerekanwe nka "inveter u" cyangwa "inveter v cyangwa w". Impamvu nuko icyiciro kimwe cyangwa ibyiciro byinshi inverter inanirwa. Niba impinga yumuyaga wa switch ari i> 3inrms, inrms ni igbt. Ibi bintu bizabaho mugihe hari ikibazo kijyanye numuyoboro wagenwe wa inverter, cyangwa harikintu kitagenda neza mumashanyarazi yingoboka yicyiciro kimwe cy irembo ryimbere. Nyuma yubu bwoko bwikosa bubaye, burashobora gutera uruziga rugufi kumusozo wanyuma wumuhinduzi wa frequence, cyangwa birashobora kandi gutuma moteri ihindagurika cyane kubera igenamigambi ridakwiye. Muri rusange hari ibintu bibiri mugihe cyo kubungabunga:
. Modulasiyo ya modulasi ni sine, kandi umutwara wikwirakwiza ni bipolar isosceles triangle wave. Ihuriro ryimyanya ya modulasiyo yumurongo hamwe nuwitwaye umurongo ugena impiswi yuruhererekane rwikiraro gisohoka icyiciro cya voltage. Akanama gashinzwe kugenzura inzugi kagerwaho hifashishijwe nini nini ihuriweho na IC (ASIC), ikubiyemo imashini itanga ibyuma bifata ibyuma bifata ibyemezo bigera kuri 0.001hz hamwe n’umuvuduko ntarengwa wa 500hz hamwe na moderi yubugari bwa pulse itanga ibyiciro bitatu bya sine Sisitemu. Iyi modulator ikora idahwitse kumurongo uhoraho wa 8khz. Umuvuduko wa voltage utanga ubundi buryo bwo kuzimya no kuzimya ibikoresho bibiri byo guhinduranya imbaraga kumaboko amwe. Niba iki cyerekezo cyumuzunguruko cyananiranye, ntigishobora kubyara ingufu za voltage mubisanzwe, kandi ikibaho kigomba gusimburwa no gusanwa.
2 Inverter igikoresho cyananiranye Igikoresho cya inverter ikoreshwa muri inverters ya Siemens ni inzugi zifunguye bipolar transistor - igbt. Igenzura riranga ni byinshi byinjira byinjira kandi ntoya cyane irembo, bityo imbaraga zo gutwara ni nto kandi irashobora gukora gusa muburyo bwo guhinduranya. Ntushobora gukora muburyo bunini. Guhindura inshuro zayo birashobora kugera hejuru cyane, ariko imikorere yayo irwanya ubukene. Niba igbt igizwe nikosa irashobora gupimwa na ohmmeter. Intambwe zihariye nizi zikurikira:
Guhagarika amashanyarazi yumurongo uhindura;
Guhagarika moteri igenzurwa;
● Koresha ohmmeter kugirango upime impedance yumusaruro usohoka hamwe na DC ihuza itumanaho a na d (reba ifoto iri kumugereka). Gupima buri kizamini kabiri uhindura polarite ya ohmmeter. Niba igbt ya frequency ihindura idahwitse, igomba kuba: kuva u2 kugeza a ni bike birwanya, bitabaye ibyo, birwanya cyane; kuva u2 kugeza d, ni ukurwanya gukomeye; bitabaye ibyo, ni ukurwanya guke. Kimwe kijya no mubindi byiciro. Iyo igbt ihagaritswe, iba ifite agaciro gakomeye ko guhangana inshuro ebyiri, kandi niba ari izunguruka-ngufi, ifite agaciro gake.

3 Kunanirwa gukoresha ingufu zananiranye Ubutumwa bwamakosa bugaragazwa nka "pulsed resistance", bivuze ko imbaraga zo gukoresha ingufu zirenze urugero. Hariho impamvu eshatu zibitera: imbaraga zo gufata feri zisubirwamo ni nyinshi cyane, imbaraga zo gufata feri ni ndende cyane cyangwa igihe cyo gufata feri ni gito cyane. Kurwanya ingufu zikoreshwa ningirakamaro. Kubera ko umutwaro wibikoresho bya fibre na chimique ari umutwaro munini wa inertia, umuyoboro mwinshi woguhindura imbaraga hamwe ningufu zikoresha ingufu zahujwe ugereranije nigice cya DC cyumuyoboro uhinduranya insinga za DA. Igikorwa cyacyo nyamukuru nuguhuza amashanyarazi Amashanyarazi agabanya umuvuduko mwinshi hejuru yumurongo wa da mugihe ufunguye, uzimye cyangwa urimo gupakira. Ariko iyo feri irenze igipimo, imikorere izahagarikwa. Muri rusange hari ibintu bibiri:
(1) Kunanirwa gukoresha ingufu zananiranye. Muburyo busanzwe bwo guhinduranya, pulse irwanya ni 7.5ω / 30kw. Nyuma yo gukoresha inverter mumyaka itari mike, kubera gutangira kenshi no guhagarara kwa inverter, résistoriste yarashyushye kandi irwanya iragabanuka. Nyamara, inverters ya Siemens ifite ibisabwa bikomeye kubiciro byayo birwanya, isabwa kuba irenze cyangwa ingana na 7.5ω. Kubwibyo, nubwo kurwanya imbaraga zikoreshwa ningufu zikoresha iyi inverter igera kuri 7.1ω, amakosa yavuzwe haruguru azabaho kandi ntabwo azashobora gutangira bisanzwe. Nyuma, nahinduye kuri power-power-resistance ifite agaciro kangana na 8ω mbere yuko ndayifungura.
(2) gutsindwa. Hano hari ikosa mugice cya igbt cya inverter, gitera ibitekerezo byisubiramo bikabije kandi binatera kunanirwa kurenza urugero rwingufu zikoresha ingufu.
4. Ubushyuhe bukabije Ubutumwa bwamakosa bugaragazwa nk "hejuru yubushyuhe" kubera ko ubushyuhe bwo gukwirakwiza ubushyuhe bwa inverter buri hejuru cyane. Ubushyuhe bwumuhinduzi uterwa ahanini nigikoresho cya inverter. Igikoresho cya inverter nacyo cyingenzi kandi cyoroshye mubice bihindura inshuro, bityo sensor yubushyuhe (ntc) ikoreshwa mugupima ubushyuhe nayo yashyizwe kumurongo wo hejuru wigikoresho cya inverter. Iyo ubushyuhe burenze 60 ℃, umuhinduzi wa frequence azabanziriza gutabaza binyuze mubimenyetso byerekana; iyo igeze kuri 70 ℃, guhinduranya imirongo izahita ihagarara kugirango yirinde. Ubushyuhe bukabije buterwa nuburyo butanu:
(1) Ubushyuhe bwibidukikije buri hejuru. Amahugurwa amwe afite ubushyuhe bwibidukikije kandi ni kure cyane yicyumba cyo kugenzura. Kugirango uzigame insinga kandi worohereze imikorere kurubuga, inverter igomba gushyirwaho kurubuga mumahugurwa. Muri iki gihe, urashobora kongeramo umuyaga ukonje mukirere cyumuyaga uhindura kugirango ufashe gukwirakwiza ubushyuhe.
(2) Kunanirwa kw'abafana. Umuyaga usohora umuyaga uhindura ni moteri ya 24v DC. Niba ibyuma bifata ibyuma byangiritse cyangwa igiceri cyaka kandi umuyaga ntuzunguruka, bizatera guhinduranya inshuro nyinshi.
(3) Icyuma gishyuha kiranduye cyane. Hano hari ibikoresho bya aluminiyumu yubushyuhe bwo gukwirakwiza inyuma ya inverter yumurongo uhindura. Nyuma yo kwiruka umwanya muremure, hanze izaba yuzuye umukungugu kubera amashanyarazi ahamye, bigira ingaruka zikomeye ku ngaruka za radiatori. Niyo mpamvu, birakenewe koza no guhanagura buri gihe.
(4) Umutwaro uremereye. Umutwaro utwarwa numuyoboro uhinduranya uremerewe igihe kinini, utera ubushyuhe. Muri iki gihe, reba amashanyarazi
