Incazelo enemininingwane ye ntombikayise isicelo module

1. Izinkambu zohlelo lokusebenza zamamojula e-SCR

Le moduli ehlakaniphile isetshenziswa kabanzi ezinhlelweni ezifana nokulawula izinga lokushisa, ukufiphala, ukuvusa amadlingozi, i-electroplating, i-electrolysis, ukushaja nokukhipha, imishini yokushisela kagesi, ama-plasma arcs, amandla kagesi e-inverter, njll., lapho amandla amandla edinga ukulungiswa nokuguqulwa, okufana nalokhu. njengemboni, ezokuxhumana, nezempi. Izilawuli ezihlukene zikagesi, izinsiza zikagesi, njll. zingaxhunywa ebhodini lokulawula lemisebenzi eminingi ngokusebenzisa imbobo yokulawula yemojuli ukuze kubonakale imisebenzi efana nokuqiniswa kwamanje, ukuqina kwamandla kagesi, ukuqala okuthambile, njll., futhi kungabona ngaphezulu kwamanje, phezu kwe-voltage, izinga lokushisa elingaphezulu, nokulinganisa. Umsebenzi wokuvikela.

2. Indlela yokulawula ye-module ye-thyristor

Ngesixhumi esibonakalayo sokulawula imojula yokufaka i-voltage eguquguqukayo noma isignali yamanje, i-voltage ephumayo yemojula ingalungiswa kahle ngokulungisa usayizi wesiginali, ukuze kuqashwe inqubo ye-voltage ephumayo yemoduli isuka ku-0V iye kunoma yiliphi iphuzu noma konke ukuqhutshwa. .

I-voltage noma isignali yamanje ingathathwa kumathuluzi okulawula ahlukahlukene, ukuphuma kwekhompyutha ye-D/A, i-potentiometer ihlukanisa ngokuqondile i-voltage kusuka kugesi we-DC nezinye izindlela; isignali yokulawula isebenzisa 0～5V, 0～10V, 4～20mA izindlela ezintathu ezivame ukusetshenziswa Ifomu lokulawula.

3. Lawula imbobo nolayini wokulawula wemojula ye-SCR

I-terminal interface yokulawula imojuli inamafomu amathathu: 5-pin, 9-pin kanye 15-pin, ehambisana 5-pin, 9-pin, futhi 15-pin control imigqa ngokulandelana. Imikhiqizo esebenzisa amasignali kagesi isebenzisa kuphela imbobo yokuqala enamaphini amahlanu, kanti amanye amaphini angenalutho. Isiginali yamanje yamaphini angu-9 iwukufaka kwesignali. Intambo yethusi yongqimba oluyisivikelo lwentambo yokulawula kufanele ishiselwe kuntambo yaphansi yamandla e-DC. Qaphela ukuthi ungaxhumi namanye amaphini. Amatheminali ane-circuited emfushane ukugwema ukungasebenzi noma ukutubeka okungenzeka kwemojuli.

Kunezinombolo kwisokhethi yembobo yokulawula imojuli kanye nesokhethi yomugqa wokulawula, sicela uhambisane ngayinye ngayinye, futhi ungahlehli uxhumano. Izimbobo ezingenhla eziyisithupha ziyizimbobo eziyisisekelo zemojuli, kanti ezinye izimbobo ziyizimbobo ezikhethekile, ezisetshenziswa kuphela emikhiqizweni enemisebenzi eminingi. Izinyawo ezisele zemikhiqizo evamile yokulawula ingcindezi ayinalutho.

4. Ithebula lokuqhathanisa lomsebenzi wephini ngalinye kanye nombala womugqa wokulawula

Inombolo yephinikhodi yomsebenzi wephini kanye nombala oholayo ohambisanayo Isixhumi samaphini angu-5 Isixhumi samaphini angu-9 Isixhumi samaphini angu-15 +12V5 (obomvu) 1 (obomvu) 1 (obomvu) GND4 (omnyama) 2 (omnyama) 2 (omnyama) GND13 (omnyama) 3 (okumnyama nokumhlophe) 3 (omnyama nokumhlophe) CON10V2 (ophuzi omaphakathi) 4 (ophuzi omaphakathi) 4 (ophuzi omaphakathi) TESTE1 (owolintshi) 5 (owolintshi) 5 (owolintshi) CON20mA 9 (onsundu) 9 (nsundu)

5. Hlangana nezimo ezidingekayo zomsebenzi wemojula ye-SCR

Kufanele kuhlangatshezwane nemibandela elandelayo lapho kusetshenziswa imojuli:

(1) +12V DC amandla kagesi: ukunikezwa kwamandla okusebenzayo kwesekethe yokulawula yangaphakathi yemojuli.

① Imfuneko kagesi ophumayo: +12V amandla kagesi: 12±0.5V, i-ripple voltage ingaphansi kuka-20mv.

② Izidingo zamanje zokukhiphayo: imikhiqizo enamanje okuzisholo angaphansi kwama-ampere angu-500: I+12V> 0.5A, imikhiqizo enamandla okuzisholo angaphezu kuka-500 ampere: I+12V> 1A.

(2) Isiginali yokulawula: 0～10V noma 4～20mA isignali yokulawula, esetshenziselwa ukulungisa i-voltage ephumayo. Isigxobo esihle sixhunywe ku-CON10V noma ku-CON20mA, futhi isigxobo esinegethivu sixhunywe ku-GND1.

(3) Ukunikezwa kwamandla nokulayisha: Ukunikezwa kwamandla ngokuvamile amandla egridi, anevoltheji engaphansi kuka-460V noma i-transformer kagesi, exhunywe kutheminali yokufaka yemojuli; umthwalo uyisisetshenziswa sikagesi, esixhunywe kutheminali ephumayo yemojuli.

6. Ubudlelwano phakathi kwe-engeli yokuqhuba kanye nomphumela wamanje wemojuli

I-engeli yokuqhuba yemojuli ihlobene ngokuqondile nenani eliphezulu lamanje elingakhishwa yimojuli. Umthamo wamanje wemojuli umkhawulo wamanje ongaphuma ku-engeli ephezulu yokuqhuba. Kwi-engeli encane yokuqhuba (isilinganiso se-voltage ephumayo ku-voltage yokufaka sincane kakhulu), inani eliphakeme lokukhiphayo lamanje likhulu kakhulu, kodwa inani elisebenzayo lamanje lincane kakhulu (amamitha e-DC ngokuvamile abonisa inani elimaphakathi, namamitha e-AC bonisa i-non-sinusoidal current, encane kunevelu yangempela) , Kodwa inani elisebenzayo le-output yamanje likhulu kakhulu, futhi ukushisa kwedivayisi ye-semiconductor kuhambisana nesikwele senani elisebenzayo, okuzokwenza ukuthi imojula shisa noma ushise. Ngakho-ke, imojula kufanele ikhethwe ukuthi isebenze ngaphezu kuka-65% we-engeli ephezulu yokuqhuba, futhi i-voltage yokulawula kufanele ibe ngaphezu kuka-5V.

7. Indlela yokukhetha yokucaciswa kwemojuli ye-SCR

Uma kucatshangelwa ukuthi imikhiqizo ye-thyristor ngokuvamile i-non-sinusoidal currents, kunenkinga ye-conduction angle kanye nomthwalo wamanje unokuguquguquka okuthile kanye nezici zokungazinzi, futhi i-thyristor chip inokumelana okungalungile nomthelela wamanje, ngakho-ke kufanele ikhethwe lapho imininingwane yamanje yemodyuli. akhethiwe. Shiya imajini ethile. Indlela yokukhetha enconyiwe ingabalwa ngokwefomula elandelayo:

I>K×I load×U maximum∕U yangempela

K: isici sokuphepha, umthwalo ophikisayo K= 1.5, umthwalo ongenisayo K= 2;

Iload: umthamo wamanje omkhulu ogeleza phakathi komthwalo; Okwangempela: i-voltage encane emthwalweni;

Umax: i-voltage ephezulu engakhishwa yimojula; (imojula yezigaba ezintathu yokulungisa izikhathi eziyi-1.35 ku-voltage yokufaka, imojuli yesilungisi yesigaba esisodwa iphindwe izikhathi ezingu-0.9 kuvoltheji yokufaka, kanti okunye ukucaciswa izikhathi ezingu-1.0);

I: Ubuncane bamanje bemojula budinga ukukhethwa, futhi umthamo wamanje wemojuli kufanele ube mkhulu kunaleli nani.

Isimo sokukhipha ukushisa kwemodyuli sihlobene ngokuqondile nempilo yesevisi kanye nomthamo wesikhashana wokulayisha ngokweqile womkhiqizo. Uma izinga lokushisa liphansi, likhulu inani lamanje eliphumayo lemojuli. Ngakho-ke, i-radiator ne-fan kufanele ifakwe ekusetshenzisweni. Kunconywa ukusebenzisa imikhiqizo enokuvikelwa kokushisa ngokweqile. Uma kunezimo zokushisa ezipholile ngamanzi, ukuchithwa kokushisa okupholile ngamanzi kuyakhethwa. Ngemuva kokubala okunzima, sinqume amamodeli we-radiator okufanele amamodeli ahlukene wemikhiqizo afakwe. Kunconywa ukusebenzisa ama-radiator namafeni ahambisana nomenzi. Lapho umsebenzisi eyilungiselela, ikhethe ngokwemigomo elandelayo:

1. Isivinini somoya se-axial flow fan kufanele sibe sikhulu kuno-6m/s;

2. Kumele ikwazi ukuqinisekisa ukuthi izinga lokushisa lepuleti elingaphansi lokupholisa alikho ngaphezu kuka-80℃ uma imojuli isebenza ngokujwayelekile;

3. Uma umthwalo wemojula ulula, ubukhulu be-radiator bungancishiswa noma ukupholisa kwemvelo kungenziwa;

4. Uma kusetshenziswa ukupholisa kwemvelo, umoya ozungeze irediyetha ungafinyelela ukuguquguquka futhi wandise ngokufanele indawo ye-radiator;

5. Zonke izikulufu zokubopha imojuli kufanele ziqiniswe, futhi amatheminali okugoqa kufanele axhunywe ngokuqinile ukuze kuncishiswe ukukhiqizwa kokushisa kwesibili. Ungqimba lwamafutha ashisayo noma iphedi elishisayo elilingana nepuleti elingaphansi kufanele lifakwe phakathi kwepuleti eliphansi lemojuli kanye nerediyetha. Ukuze kuzuzwe umphumela omuhle kakhulu wokushisa ukushisa.

8. Ukufakwa nokugcinwa kwemodyuli ye-thyristor

(1) Gcoba ungqimba lwamafutha abicah aguqulayo ashisayo ebusweni bepuleti elingaphansi elibamba ukushisa lemojuli kanye nangaphezulu kwerediyetha ngokulinganayo, bese ulungisa imojuli kurediyetha ngezikulufu ezine. Ungaqinisi izikulufo zokulungisa ngesikhathi. Ngokulinganayo, phinda izikhathi eziningana kuze kube yilapho iqinile, ukuze ipuleti eliphansi lemodule lisondelene eduze nobuso be-radiator.

(2) Ngemva kokuhlanganisa irediyetha nefeni ngokuvumelana nezidingo, zilungise ziqonde endaweni efanele ye-chassis.

(3) Bopha intambo yethusi ngokuqinile ngetheyiphu yeringi yekhanda, okungcono kakhulu ecwiliswe ethini, bese ufaka ishubhu elikwazi ukushwabana nokushisa, futhi uyishise ngomoya oshisayo ukuze inciphe. Lungisa ukuphela kwetheminali ku-electrode yemojuli futhi ugcine ukuxhumana okuhle kwengcindezi yendiza. Akuvunyelwe ngokuphelele ukucwilisa ucingo lwethusi lwekhebula ngqo ku-electrode yemojula.

(4) Ukuze kunwetshwe impilo yesevisi yomkhiqizo, kunconywa ukuwugcina njalo ezinyangeni ezi-3-4, esikhundleni samafutha ashisayo, susa uthuli olungaphezulu, futhi uqinise izikulufu zokubopha.

Inkampani incoma imikhiqizo yamamojula: Imodyuli ye-MTC thyristor, imodyuli ye-MDC rectifier, imojula ye-MFC, njll.
