Kufotokozera mwatsatanetsatane khalidal ntchito module

1. Magawo ogwiritsira ntchito ma module a SCR

gawo anzeru ichi chimagwiritsidwa ntchito monga kulamulira kutentha, dimming, excitation, electroplating, electrolysis, kulipiritsa ndi kutulutsa, makina kuwotcherera magetsi, plasma arcs, inverter magetsi, etc., kumene mphamvu mphamvu ayenera kusinthidwa ndi kusinthidwa, monga monga mafakitale, mauthenga, ndi asilikali. Zowongolera zamagetsi zosiyanasiyana, zida zamagetsi, ndi zina zambiri zitha kulumikizidwa ndi bolodi yoyendetsera ntchito zambiri kudzera pa doko loyang’anira gawoli kuti muzindikire ntchito monga kukhazikika kwapano, kukhazikika kwamagetsi, kuyambika kofewa, ndi zina zambiri, ndikuzindikira pazomwe zikuchitika, pa voteji, kutentha kwambiri, ndi kufananiza. Ntchito yoteteza.

2. Njira yoyendetsera gawo la thyristor

Kupyolera mu gawo lolowera gawo lowongolera mawonekedwe osinthika voteji kapena chizindikiro chapano, mphamvu yotulutsa gawoli imatha kusinthidwa bwino posintha kukula kwa siginecha, kuti muzindikire momwe ma module amatulutsira magetsi kuchokera ku 0V kupita kumalo aliwonse kapena ma conduction onse. .

Voltage kapena chizindikiro chapano chikhoza kutengedwa kuchokera ku zida zosiyanasiyana zowongolera, zotulutsa zapakompyuta za D / A, potentiometer imagawanitsa magetsi kuchokera kumagetsi a DC ndi njira zina; chizindikiro chowongolera chimatenga 0～5V, 0～10V, 4～20mA njira zitatu zomwe zimagwiritsidwa ntchito kwambiri Kuwongolera mawonekedwe.

3. Kuwongolera doko ndi mzere wowongolera wa SCR module

Ma module control terminal ali ndi mitundu itatu: 5-pin, 9-pin ndi 15-pin, yofanana ndi 5-pin, 9-pin, ndi 15-pin control mizere motsatana. Zogulitsa zomwe zimagwiritsa ntchito ma siginecha amagetsi zimangogwiritsa ntchito mapini asanu oyamba, ndipo zina zonse zimakhala zopanda kanthu. Chizindikiro chamakono cha 9-pini ndicholowetsa chizindikiro. Waya wamkuwa wagawo lotchinga la waya wowongolera uyenera kuwotcherera ku waya wamagetsi wa DC. Samalani kuti musagwirizane ndi zikhomo zina. Ma terminal ndi ofupikitsidwa kuti apewe kusagwira ntchito kapena kutha kwa module.

Pali manambala pa socket yowongolera doko ndi socket yowongolera, chonde lemberani imodzi ndi imodzi, ndipo musasinthe kulumikizana. Madoko asanu ndi limodzi omwe ali pamwambapa ndi madoko oyambira a gawoli, ndipo madoko ena ndi madoko apadera, omwe amangogwiritsidwa ntchito pazinthu zokhala ndi ntchito zambiri. Mapazi otsala azinthu zowongolera kuthamanga kwanthawi zonse alibe kanthu.

4. Gome lofananitsa la ntchito ya pini iliyonse ndi mtundu wa mzere wolamulira

Nambala ya pini yogwira ntchito ndi mtundu wotsogola wofananira 5-pini cholumikizira 9-pini cholumikizira 15-pini cholumikizira +12V5 (wofiira) 1 (wofiira) 1 (wofiira) GND4 (wakuda) 2 (wakuda) 2 (wakuda) GND13 (wakuda) 3 (wakuda ndi oyera) 3 (wakuda ndi oyera) CON10V2 (wachikasu wapakatikati) 4 (wachikasu wapakatikati) 4 (wachikasu wapakatikati) TESTE1 (lalanje) 5 (lalanje) 5 (lalanje) CON20mA 9 (bulauni) 9 (bulauni)

5. Pezani zofunikira pa ntchito ya SCR module

Zinthu zotsatirazi ziyenera kukwaniritsidwa mukamagwiritsa ntchito module:

(1) + 12V DC magetsi: mphamvu yogwira ntchito yozungulira gawo lamkati la gawo.

① Kufunika kwa voteji: + 12V magetsi: 12 ± 0.5V, voliyumu ya ripple ndi yosakwana 20mv.

② Zofunikira pakalipano: Zogulitsa zomwe zili ndi ma amperes mwadzina pano: I+500V> 12A, zopangidwa ndi ma amperes 0.5 mwadzina: I+500V> 12A.

(2) Chizindikiro chowongolera: 0 ~ 10V kapena 4 ~ 20mA chizindikiro chowongolera, chomwe chimagwiritsidwa ntchito kusintha mphamvu yamagetsi. Pole yabwino imalumikizidwa ndi CON10V kapena CON20mA, ndipo mtengo woyipa umalumikizidwa ndi GND1.

(3) Magetsi ndi katundu: Mphamvu yamagetsi nthawi zambiri imakhala mphamvu ya gridi, yokhala ndi voteji pansi pa 460V kapena chosinthira magetsi, cholumikizidwa ndi gawo lolowera gawo; katunduyo ndi chipangizo chamagetsi, cholumikizidwa ndi gawo lotulutsa la module.

6. Ubale pakati pa angle conduction ndi zotuluka panopa module

Njira yoyendetsera ma module imagwirizana mwachindunji ndi kuchuluka kwaposachedwa komwe module imatha kutulutsa. Zomwe zilipo panopa za module ndizomwe zimakhalapo zomwe zingathe kutulutsa pamlingo waukulu wa conduction. Pang’onoting’ono ya conduction (chiwerengero cha voteji yotulutsa ku voliyumu yolowera ndi yaying’ono kwambiri), nsonga yaposachedwa ndi yayikulu kwambiri, koma mtengo wake wapano ndi wocheperako (mamita a DC nthawi zambiri amawonetsa mtengo wapakati, ndi ma AC metres. wonetsani sinusoidal panopa, yomwe ndi yaying’ono kusiyana ndi mtengo weniweni) , Koma mtengo wogwira ntchito wamakono ndi waukulu kwambiri, ndipo kutentha kwa chipangizo cha semiconductor kumayenderana ndi malo amtengo wapatali, zomwe zidzachititsa kuti gawoli liwonongeke. kutenthetsa kapena ngakhale kuyaka. Chifukwa chake, gawoli liyenera kusankhidwa kuti ligwire ntchito pamwamba pa 65% ya ngodya yayikulu yoyendetsera, ndipo mphamvu yowongolera iyenera kukhala pamwamba pa 5V.

7. Njira yosankhidwa ya ma module a SCR

Poganizira kuti mankhwala thyristor zambiri sanali sinusoidal mafunde, pali vuto la conduction ngodya ndi katundu panopa ali kusinthasintha zina ndi kusakhazikika zinthu, ndi thyristor Chip ali kukana osauka kukhudza panopa, choncho ayenera kusankhidwa pamene module panopa specifications. amasankhidwa. Siyani malire ena. Njira yosankhidwa yovomerezeka ikhoza kuwerengedwa motsatira njira iyi:

I> K×I load×U maximum∕U zenizeni

K: chitetezo, katundu wotsutsa K= 1.5, katundu wolowetsa K= 2;

Iload: pazipita panopa ikuyenda kudzera katundu; Zowona: voteji yochepa pa katundu;

Umax: mphamvu yayikulu yomwe module imatha kutulutsa; (gawo lokonzanso magawo atatu ndi 1.35 kuwirikiza voteji, gawo limodzi lokonzanso gawo ndi 0.9 kuwirikiza voteji yolowera, ndipo zinanso ndi ka 1.0);

I: Zochepa zomwe zili mu module ziyenera kusankhidwa, ndipo zomwe zili mu module ziyenera kukhala zazikulu kuposa izi.

Chikhalidwe cha kutentha kwa gawoli chikugwirizana mwachindunji ndi moyo wautumiki ndi mphamvu yanthawi yochepa ya katunduyo. Kutsika kwa kutentha, kumapangitsanso kutuluka kwa module. Chifukwa chake, ma radiator ndi fan ayenera kukhala okonzeka kugwiritsidwa ntchito. Ndi bwino kugwiritsa ntchito mankhwala ndi kutenthedwa chitetezo. Ngati pali mikhalidwe yotaya kutentha kwamadzi, kutayika kwa kutentha kwamadzi kumakhala koyenera. Pambuyo powerengera mozama, tatsimikiza ma radiator omwe mitundu yosiyanasiyana yazinthu iyenera kukhala nazo. Ndikofunikira kugwiritsa ntchito ma radiator ndi mafani omwe amafanana ndi wopanga. Wogwiritsa ntchito akakonzekera, sankhani motsatira mfundo zotsatirazi:

1. Kuthamanga kwa mphepo ya axial flow fan iyenera kukhala yaikulu kuposa 6m / s;

2. Iyenera kuonetsetsa kuti kutentha kwa mbale yoziziritsa pansi sikuposa 80 ℃ pamene gawoli likugwira ntchito bwino;

3. Pamene katundu wa module ali wopepuka, kukula kwa radiator kumatha kuchepetsedwa kapena kuzirala kwachilengedwe kungatengedwe;

4. Pamene kuzirala kwachilengedwe kumagwiritsidwa ntchito, mpweya wozungulira radiator ukhoza kupititsa patsogolo ndikuwonjezera malo a radiator;

5. Zomangira zonse zomangirira gawoli ziyenera kumangika, ndipo ma crimping terminals ayenera kulumikizidwa mwamphamvu kuti achepetse kubadwa kwa kutentha kwachiwiri. Chosanjikiza chamafuta otenthetsera kapena padi yotentha kukula kwa mbale yapansi iyenera kuyikidwa pakati pa mbale yapansi ya module ndi radiator. Kuti mukwaniritse zotsatira zabwino kwambiri zowononga kutentha.

8. Kuyika ndi kukonza gawo la thyristor

(1) Valani mafuta osanjikiza a silicone pamwamba pa mbale ya pansi yoyendetsa kutentha kwa module ndi pamwamba pa rediyeta mofanana, ndiyeno konzani gawolo pa radiator ndi zomangira zinayi. Musamangitse zomangira pa nthawi imodzi. Mogwirizana, bwerezani kangapo mpaka mutakhazikika, kotero kuti mbale yapansi ya module ikugwirizana kwambiri ndi pamwamba pa radiator.

(2) Mutatha kusonkhanitsa radiator ndi fani malinga ndi zofunikira, zikonzeni molunjika pamalo oyenera a chassis.

(3) Mangani waya wa mkuwa molimba ndi tepi ya mphete ya mutu, makamaka yomizidwa mu malata, kenaka muyike pa chubu chotchinga kutentha, ndikutenthetsa ndi mpweya wotentha kuti muchepetse. Konzani mapeto a terminal pa electrode ya module ndikusunga kukhudzana kwabwino kwa ndege. Ndi zoletsedwa crimp waya wamkuwa wa chingwe mwachindunji pa electrode module.

(4) Pofuna kupititsa patsogolo moyo wautumiki wa mankhwalawa, tikulimbikitsidwa kuti tipitirizebe miyezi 3-4, m’malo mwa mafuta otentha, kuchotsa fumbi pamwamba, ndikumangitsa zomangira.

Kampaniyo imalimbikitsa zinthu za module: MTC thyristor module, MDC rectifier module, MFC module, etc.
