Kev siv cov thyristor-based chargers yog qhov ncaj ncees - qhov rov qab ntawm cov roj teeb tau nrawm dua thiab "muaj tseeb dua". Qhov zoo tshaj plaws ntawm cov nqi them tam sim no, qhov hluav taws xob yog tswj xyuas, yog li nws tsis zoo li nws yuav ua rau muaj kev puas tsuaj rau lub roj teeb. Tom qab tag nrho, electrolyte tuaj yeem boil kom deb ntawm overvoltage, cov hlau lead tuaj yeem tawg. Thiab tag nrho cov no ua rau tsis ua hauj lwm ntawm lub roj teeb. Tab sis koj yuav tsum nco ntsoov tias cov roj teeb lead-acid niaj hnub tuaj yeem tiv taus tsis pub ntau tshaj 60 qhov kev tso tawm tag nrho thiab them cov voj voog.

piav qhia dav dav ntawm lub charger circuit

Txhua tus tuaj yeem ua thyristor chargers nrog lawv tus kheej tes yog tias lawv muaj kev paub txog hluav taws xob engineering. Tab sis txhawm rau ua txhua yam haujlwm kom raug, koj yuav tsum muaj yam tsawg kawg nkaus ntsuas qhov yooj yim ntawm tes - multimeter.

Nws tso cai rau koj ntsuas qhov hluav taws xob, tam sim no, tsis kam, xyuas qhov ua tau zoo ntawm transistors. Thiab nyob rau hauv lub charger circuits muaj xws li functional blocks:

1. Nyobntaus ntawv - nyob rau hauv cov ntaub ntawv yooj yim tshaj plaws, qhov no yog ib qho yooj yim transformer.
2. Lub tsev rectifier muaj ib, ob lossis plaub lub semiconductor diodes. Ib qho txuas txuas txuas feem ntau yog siv, raws li nws tuaj yeem siv kom tau txais yuav luag ncaj qha tam sim no tsis muaj ripple.
3. Ib lub lim dej yog ib lossis ntau dua electrolytic capacitors. Nrog lawv cov kev pab, tag nrho cov khoom sib txawv hauv cov zis tam sim no raug txiav tawm.
4. Voltage stabilization yog nqa tawm siv cov khoom tshwj xeeb semiconductor - zener diodes.
5. Ammeter thiab voltmeter tswj tam sim no thiab voltage, feem.
6. Cov zis tam sim no tsis tau hloov kho los ntawm cov cuab yeej sib sau ua ke ntawm cov transistors, thyristor thiab kuj sib txawv.

Lub ntsiab tseem ceeb yog transformer

Yog tsis muaj nws, nws tsis nyob qhov twg, nws tsis tuaj yeem ua lub charger nrog kev tswj hwm ntawm thyristor yam tsis siv lub tshuab hloov pauv. Lub hom phiaj ntawm kev siv lub tshuab hloov pauv yog txo qhov voltage ntawm 220 V mus rau 18-20 V. Qhov ntawd yog qhov xav tau ntau npaum li cas rau kev ua haujlwm ntawm lub charger. General tsim ntawm transformer:

1. Magnetic core ua los ntawm steel daim hlau.
2. Primary winding txuas nrog AC 220V.
3. Lub voj voog thib ob txuas nrog lub rooj tsav tsheb loj.

Hauv qee qhov qauv tsim, ob lub voj voog thib ob txuas nrog hauv koob tuaj yeem siv tau. Tab sis nyob rau hauv tus tsim uas tau tham nyob rau hauv tsab xov xwm, ib tug transformer yog siv, uas muaj ib tug thawj thiab tib lub thib ob windings.

Rawsxam ntawm transformer windings

Nws yog qhov tsim nyog siv lub tshuab hloov pauv nrog lub tshuab hluav taws xob uas twb muaj lawm hauv kev tsim lub thyristor charger. Tab sis yog tias tsis muaj thawj winding, koj yuav tsum xam nws. Txhawm rau ua qhov no, nws yog txaus kom paub lub zog ntawm cov cuab yeej thiab thaj tsam ntawm qhov sib nqus ntawm qhov sib nqus. Nws raug nquahu kom siv cov transformers nrog lub zog ntawm 50 watts. Yog hais tias tus ntoo khaub lig ntawm qhov sib nqus Circuit Court S (sq. cm) paub, koj tuaj yeem xam cov lej ntawm txhua qhov 1 V ntawm qhov voltage:

N=50 / S (sq cm).

Txhawm rau suav cov lej ntawm qhov kev hloov pauv hauv thawj qhov cua, koj yuav tsum muab 220 los ntawm N. Qhov thib ob winding yog xam raws li qhov qub. Tab sis nco ntsoov tias nyob rau hauv ib lub tsev network, qhov voltage tuaj yeem dhia mus txog 250 V, yog li lub transformer yuav tsum tiv taus cov tee ntawd.

Cua thiab sib dhos ntawm transformer

Ua ntej koj pib winding, koj yuav tsum xam lub cheeb ntawm cov hlau uas koj xav siv. Txhawm rau ua qhov no, siv tus qauv yooj yim:

d=0.02 × √I (windings).

Ntu ntu ntawm cov xaim yog ntsuas hauv millimeters, qhov winding tam sim no yog milliamps. Yog tias koj xav tau them nrog tam sim no ntawm 6 A, ces hloov tus nqi ntawm 6000 mA hauv qab lub hauv paus.

Tau suav tag nrho cov ntsuas ntawm lub transformer, pib winding. Muab lub coil rau coil sib npaug kom lub winding haum rau lub qhov rais. Txhim kho qhov pib thiab xaus - nws yog ib advisable mus solder lawv mus dawb hu (yog tias muaj). Sai li nws npaj tauwinding, nws muaj peev xwm sib sau ua ke transformer steel daim hlau. Nco ntsoov ua kua roj vanish cov xov hlau tom qab winding tiav, qhov no yuav tshem tawm cov suab nrov thaum ua haujlwm. Cov phaj tseem ceeb kuj tuaj yeem kho nrog cov tshuaj nplaum tom qab sib dhos.

YPCB manufacturing

Ua kom koj tus kheej thyristor lub tsheb roj teeb charger Circuit Board, koj yuav tsum muaj cov ntaub ntawv thiab cov cuab yeej hauv qab no:

1. Acid rau kev ntxuav cov khoom ntawm cov ntawv ci.
2. Solder thiab tin.
3. Foil textolite (getinax nyuaj dua kom tau txais).
4. xyaum me me thiab 1-1.5 hli laum khoom.
5. Ferric chloride. Nws yog qhov zoo dua los siv cov reagent no, vim nws tshem tawm cov tooj liab ntau dua sai dua.
6. Marker.
7. Laser tshuab luam ntawv.
8. Iron.

Ua ntej koj pib kho, koj yuav tsum kos cov kab. Nws yog qhov zoo tshaj los ua qhov no hauv lub computer, tom qab ntawd luam daim duab ntawm lub tshuab luam ntawv (xws li laser).

Kev luam ntawv yuav tsum tau nqa tawm ntawm ib daim ntawv los ntawm cov ntawv xov xwm glossy. Daim duab yog txhais yooj yim heev - daim ntawv yog rhuab nrog ib tug kub hlau (tsis muaj fanaticism) rau ob peb feeb, ces nws txias rau ib pliag. Tab sis koj tuaj yeem kos txoj hauv kev los ntawm tes nrog tus cim, thiab tom qab ntawd muab cov ntawv sau rau hauv cov tshuaj ferric chloride rau ob peb feeb.

Txoj kev nco cov ntsiab lus

Ib qho khoom siv raws li theem-pulse maub los ntawm thyristor tab tom ua haujlwm. Nws tsis muaj cov khoom tsis tshua muaj, yog li, muab qhov ntawdkoj yuav mount serviceable qhov chaw, tag nrho cov Circuit Court yuav ua hauj lwm yam tsis muaj tuning. Cov qauv tsim muaj cov hauv qab no:

1. Diodes VD1-VD4 yog tus choj rectifier. Lawv tsim los hloov AC rau DC.
2. Cov chav tswj tau sib sau ua ke ntawm unijunction transistors VT1 thiab VT2.
3. Lub sijhawm them nyiaj ntawm lub capacitor C2 tuaj yeem hloov kho los ntawm qhov sib txawv tsis sib xws R1. Yog tias nws lub rotor hloov mus rau qhov chaw zoo tshaj plaws, ces qhov them tam sim no yuav yog qhov siab tshaj.
4. VD5 yog lub diode tsim los tiv thaiv thyristor tswj Circuit Court los ntawm qhov hluav taws xob rov qab uas tshwm sim thaum qhib.

Cov tswv yim no muaj ib qho teeb meem loj - qhov hloov pauv loj hauv cov nqi them tam sim no yog tias lub network voltage tsis ruaj khov. Tab sis qhov no tsis yog ib qho kev cuam tshuam yog tias siv lub zog stabilizer hauv tsev. Koj tuaj yeem sib sau ua ke lub charger ntawm ob lub thyristors - nws yuav ruaj khov dua, tab sis nws nyuaj dua rau kev siv cov qauv no.

Mounting ntsiab ntawm lub rooj tsavxwm luam tawm

Nws yog ntshaw kom mount diodes thiab thyristor ntawm cov radiators cais, thiab nco ntsoov cais lawv ntawm rooj plaub. Tag nrho lwm cov ntsiab lus raug ntsia rau ntawm lub rooj tsav xwm luam tawm.

Nws yog qhov tsis xav siv dai mounting - nws zoo li dab tuag dhau lawm, thiab txaus ntshai. Txhawm rau tso cov khoom rau ntawm lub rooj tsavxwm, koj xav tau:

1. Txhob qhov rau ob txhais ceg nrog lub laum nyias.
2. Tin tag nrho cov ntawv luam tawm.
3. Txhob lo rau txoj kab nrog txheej nyias nyias, qhov no yuav ua kom lub installation ruaj ntseg.
4. Nruab tag nrhokhoom thiab solder lawv.

Tom qab kev teeb tsa tiav, koj tuaj yeem npog cov kab nrog epoxy lossis kua roj vanish. Tab sis ua ntej ntawd, nco ntsoov txuas lub transformer thiab cov xov hlau uas mus rau lub roj teeb.

Kev sib dhos zaum kawg ntawm lub cuab yeej

Tom qab kev teeb tsa ntawm lub charger ntawm KU202N thyristor, koj yuav tsum nrhiav cov ntaub ntawv tsim nyog rau nws. Yog tias tsis muaj dab tsi tsim nyog, ua rau koj tus kheej. Koj tuaj yeem siv cov hlau nyias lossis txawm tias plywood. Muab cov transformer thiab radiators nrog diodes, thyristor nyob rau hauv ib qho chaw yooj yim. Lawv yuav tsum tau txias kom zoo. Rau lub hom phiaj no, koj tuaj yeem nruab ib lub tshuab txias rau hauv qab phab ntsa.

Koj tuaj yeem nruab lub tshuab hluav taws xob tsis siv lub fuse (yog tias qhov ntev ntawm lub cuab yeej tso cai). Nyob rau hauv pem hauv ntej vaj huam sib luag koj yuav tsum tau muab ib tug ammeter thiab ib tug kuj tsis paub meej resistor. Tom qab sib sau ua ke tag nrho cov ntsiab lus, mus sim lub cuab yeej thiab nws txoj haujlwm.
