Ibyiciro by'ibanze
1. Igikoresho cya voltage igenzura gishobora kugabanywamo: ukurikije ihame ryakazi:
(1) Menyesha umuyobozi wa voltage
Umuyoboro wa voltage ukoreshwa hakiri kare, iyi mikorere yoguhuza kwinyeganyeza yinyeganyeza iratinda, hariho inertia ya mashini na inertia ya electromagnetique, kugenzura neza imbaraga za voltage, guhuza byoroshye kubyara ibicanwa, kwivanga kwa radio nini, kutizerana nabi, ubuzima bucye, byavanyweho.
(2) Umugenzuzi wa Transistor
Hamwe niterambere ryikoranabuhanga rya semiconductor, hafashwe ingamba zo kugenzura transistor.Ibyiza byayo ni: guhinduranya tristoriste ni ndende, kandi ntabwo itanga ibicanwa, guhuza neza, ariko kandi ifite ibyiza byuburemere bworoshye, ubunini buto, ubuzima burebure, kwizerwa cyane, kwivanga kwa radio nto, nibindi, kandi ubu ni byinshi ikoreshwa muri Dongfeng, Jiefang hamwe na moderi zitandukanye zo hasi.
3) Igenzura ryumuzunguruko
Usibye ibyiza byabashinzwe kugenzura transistor, imiyoboro yumuzunguruko ihuriweho nayo ni ultra-nto, igashyirwa imbere muri generator (izwi kandi nk'iyubatswe mu kugenzura), kugabanya insinga zo hanze, kandi ingaruka zo gukonjesha zaratejwe imbere, kandi ubu zikoreshwa cyane muri Santana.Audi hamwe nizindi moderi ya sedan.
(4) Igenzura rya mudasobwa
Nyuma yo gupima umutwaro wose wa sisitemu ukoresheje moteri yumuriro wamashanyarazi, ikimenyetso cyoherezwa kuri mudasobwa ya generator, hanyuma amashanyarazi ya generator agenzurwa na mudasobwa ya moteri, hanyuma umuzenguruko wumurongo wa magneti ukazimya no kuzimya mugihe gikwiye. , ni ukuvuga, imikorere isanzwe ya sisitemu yamashanyarazi irashobora kwizerwa rwose, bateri irashobora kwishyurwa bihagije, kandi umutwaro wa moteri urashobora kugabanuka kandi ubukungu bwa peteroli burashobora kunozwa.Kurugero, Shanghai Buick, Guangzhou Honda hamwe nandi mashanyarazi akoresha iyi mikorere.
2. Igenzura rya voltage
Ukurikije guhuza ibyuma bisimburana byubwoko birashobora kugabanywamo:
(1) Imbere yubwoko bwicyuma
Igenzura rya voltage ikwiranye no guhuza imbere-ubwoko bwa karuvati yiswe iyitwa karuvati yimbere;
(2) Igenzura ryubwoko bwicyuma
Igenzura rya voltage ikwiranye no guhuza ubwoko bwa karuvati yo hanze yiswe ibyuma byuma-byuma.
Muburyo bwo gukoresha, kubagenzuzi ba transistor, nibyiza gukoresha igenzura ryerekanwe mumfashanyigisho yimodoka, niba izindi moderi zikoreshwa mugusimbuza, hiyongereyeho voltage nominal nibindi bipimo byagenwe kandi nubuyobozi bwambere ni bumwe, umugenzuzi usimbuye agomba kuba ameze nkicyuma cyambere cyabashinzwe kugenzura ibyuma, bitabaye ibyo, generator ntishobora gukora neza kubera umuzunguruko.Kubashinzwe guhuza imiyoboro ihuriweho, bigomba kwitanga kandi ntibishobora gusimburwa.
Koresha kubungabunga
Koresha kubungabunga
Umugenzuzi muri rusange ntabwo yemerewe gusenya igifuniko mugihe cyo gukoresha, kandi ibintu bisanzwe ni ugukora igenzura ryuzuye no kubungabunga buri 200h cyangwa irenga, kandi ibiyikubiyemo nibi bikurikira:
1.Kuraho urubanza hanyuma ugenzure ahabigenewe kugirango umwanda wangiritse.Niba hari umwanda, ohanagura hejuru yamakuru ukoresheje impapuro zisukuye.Niba umubonano wavanyweho cyangwa utaringaniye kandi umubonano ukaba muke, mubisanzwe byoroha hamwe numusenyi "00" cyangwa umusenyi, hanyuma ugahanagurwa nimpapuro zisukuye.
2.Reba ubukana bwa buri muhuza, bapima ubukana nagaciro kangana na buri coil.Niba hari ibyangiritse, bigomba gusanwa cyangwa gusimburwa nigice gishya mugihe.
3.Reba umuyaga ufunga ninyuma yumurongo wubu, icyuma ntarengwa cyumubyigano wa voltage, imipaka ntarengwa yumubare wubu uhagarara, hamwe nu cyuho nicyuho cyumuyaga muburyo butandukanye.Niba bidahuye n'ibisabwa, bigomba guhinduka.
4.Reba ibiyobora byahinduwe kandi witondere kwerekana ibyerekana ammeter yerekana igihe utangiye moteri ya mazutu.Niba urushinge rwa ammeter rugikomeza kwerekeza kuruhande rwa "-" mugihe moteri ya mazutu ikora kumuvuduko uringaniye cyangwa hejuru, ibi bivuze ko guhuza kwamashanyarazi kurubu bitaciwe, kandi nubutaka bugomba guhita bwihagarika;Bitabaye ibyo, byangiza bateri, umugenzuzi, amashanyarazi yumuriro, nibindi. Niba urushinge rwa ammeter rugikomeza kwerekana "0" nyuma ya moteri ya mazutu itangiye umuvuduko wateganijwe, guhindura ibisobanuro ntabwo byahinduwe ukurikije ibisabwa bya tekiniki. , kandi bigomba kongera kugenzurwa no guhindurwa.
