Sida loo sameeyo jaangooyaha korontada birta, kabida, a a? control Power waayo, kabida, gacmahooda, oo nidaamka iyo edbinta

Qalabka loogu talagalay hagaajinta heerka danab ku bixisey in element kulaylku, hams ayaa badanaa loo isticmaalaa si looga hortago in failure dhicis ah ee caarada, kabida iyo tayada kabida. Fikirka ugu badan ee xakameeya awood kooban shido dvuhpozitronnye xiriir kabida, iyo qalabka SCR rakibay in hayayaashii. Kuwani iyo qalabka kale siiyaan awood u leeyahay inuu xusho heerka danab la doonayo. Maanta isticmaalo goobaha macmal ah oo warshad.

Simple, kabida jaangooyaha awood

Haddii aad rabto in aad si aad u hesho a kabida, bir 40 W 100 W lagu saleyn karaa on triac Bannaanka BT 138-600. Waxaa ka shaqeeya by jarida la ruxruxo Culumida Soomaaliyeed. Heerka xiirid iyo heerkulka kululaynta laga beddeli karaa iyadoo la isticmaalayo resistor R1. laambad iyakana u adeegtaa sida tilmaame. Si aad u dhigay, ma aha lagama maarmaan. At hiitarka waa triac rakibay BT 138-600.

guryaha

nidaamka oo dhan waa in ay daruuri tahay in lagu meeleeyaa guryaha xidhan dielectric. waxay doonayaan in la sameeyo qalab Ghadafi waa in aan u saameeya nabdoonaanta markii ay la isticmaalayo. Ogsoonow in qalabka hawl ka il danab of 220 V. a

SCR jaangooyaha awood kabida,

Tusaale ahaan, ka fiirsan qalab, loogu talagalay load a of dhowr watts boqolaal. kala duwan Regulation awoodda lagu qiimeeyo ee qalabka kala duwan tahay 50% si ay u 97%. Qalabka wuxuu u isticmaalaa a haysta hadda KU103V SCR ka yar hal milliampere.

Iyada oo diode ku VD1 si xor ah u gudbin danab bar-ruxruxo negative, bixinta ku saabsan nus ka mid ah awoodda guud ee birta, kabida. Waxaa laga beddeli karaa VS1 SCRs inta lagu guda jiro kasta bar-wareegga wanaagsan. qalab ayaa la wareegay VD1 diode antiparallel. SCR positionally gacanta ku mabda '. matoor The abuuraa karsado aqbasho at koronto gacanta ku kooban circuit R5R6C1 qeexaya wakhtiga iyo transistor unijunction.

resistor xamili tireedyada R5 go'aamiso wakhtiga wareegga badhkiis wanaagsan. nidaamka xakamaynta Power u baahan tahay xasilooni iyo heerkulka wanaagsan difaac buuq. Tan waxaa loo shunted kartaa maaraynta resistor guurka R1.

silsilad R2R3R4VT3

digir danab Generator quudin jiray in 7b iyo muddada ka mid ah 10 Ms, qaabeeya silsilad R2R3R4VT3. Badallo VT3 transistor waa element a xasilinta. Waxaa la shaqeysiin jihada dambe. Bannaanka xoogga baaba'aan resistors Red2-R4, waa la dhimi doonaa.

Wadista jaangooyaha awood ka mid ah capacitor S1KM5, resistors - MLT iyo R5 - SP 0.4. transistor waxaa loo isticmaali karaa midkood.

Board iyo guryaha ee qalabka

Maxaa yeelay, ururkii qalab ku haboon guddiga Maro adag bireed of 36 mm dhexroor iyo 1 mm qaro weyn ee. Waayo, kiiska, waxaad isticmaali kartaa wax kasta oo alaabta, sida sanduuq caag ama xaaladood oo wax la ningax fiican. Waxaad u baahan tahay saldhig hoos xubno fargeeto. Ujeedada this bireed waxaa laga yaabaa in ay Alxan laba nuts 2,5 M si musmaarradii waxaa lagu tuujiyey guddiga guryaha lagu jiro shirka.

Qasaaraha SCRs KU202

Haddii xoogga a bir yar, kabida, xeerka ayaa suuragal ah keliya in cidhiidhi ah nus-wareeg. The mid meesha ka hor joogsataan SCRs danab ugu yaraan wax yar ka hooseeya load hadda. xasiloonida heerkulka ma lagu gaari karaa iyadoo la isticmaalayo sida jaangooyaha xoog ah, kabida.

jaangooyaha tallaabo-up The

Qalabka intooda badan kaliya on awood hoos u shaqeeya si ay u xasilin heerkulka. danab qabashada noqon kartaa 50-100%, ama ka 0-100%. awood kabida, waxaa laga yaabaa in aan ku filnayn in ay dhacdo korontada 220 V ama ka hooseeya, tus, weyn vypayat card jir ah haddii loo baahdo.

danab Operating waxaa smoothed by capacitor electrolytic, kordhay 1.41 jeer iyo quudiyaa birta, kabida. awoodda joogtada ah, hagaajin on capacitor gaaro 310 V at 220 V. Awoodda si mug leh, heerkulka kulaylku waa la heli karaa xitaa at 170 V.

kabida, awood badan uma baahna in la kordhiyo hay'adaha sharciga.

Qaybo ka mid looga baahan yahay nidaamka

Si ay u ururiyaan jaangooyaha awood user-saaxiibtinimo bir ah, kabida gacmahaaga, waxaad isticmaali kartaa habka dusha sii kordhaya dhow outlet ah. Waxay u baahan tahay qaybaha yar oo cabbirkooda. Power resistor hal waa in ay ahaadaan aan ka yarayn 2 W, iyo kuwa kale - 0.125 watts.

Description of nidaamka si loo hagaajiyo jaangooyaha awoodda

In capacitor ku electrolytic C1 loo qaybiyay la rectifier aqbasho buundada VD1. danab hawlgalka Its waa in aanay noqon wax ka yar 400 V. In FET qayb IRF840 jaangooyaha ku yaal geysto. Tan iyo qalab this isticmaali kartaa bir ah, kabida, in 65 W leh hiitarka ah. Waxay hore loo kululayn karaa kor ku heerkulka la doonayo, xitaa la siin a awood dhimay.

transistor maamulka ee muhiimka ah kaalinta on DD1 chip, soo saaray matoor PWM kuwaas oo inta jeer ayaa lagu wadaa by C2 capacitor ah. stabilizer Parametric dhajinta on qalabka C3, R5 iyo VD4. Waxa uu leeyahay DD1 jab ah.

Si loo ilaaliyo transistor wax soo saarka ayaa lagu wadaa ka VD5 diode inductance ah. Waxa aan la hagaajin karo haddii ay gacanta ku xooggii birta, kabida ah ma loo isticmaali doonaa qalabka kale ee korontada.

Suurtagalnimada bedelo qaybo in ilaaliyaal ah

DD1 chip waxaa lagu beddeli karaa by K561LA7. buundada Rectifier laga sameeyey oo dioska- loogu talagalay hadda ugu yar ee 2A. qalab IRF740 loo isticmaali karaa sida transistor wax soo saarka ah. Bannaanka uma baahna lifaaqa, haddii faahfaahinta oo dhan ay sax yihiin, iyo haddii aan la oggol yahay qalad shirka.

qalab kale oo suuragal ah in danab guraysay

Just socday circuit jaangooyaha xoogga, waayo, kabida, ka shaqeeya symistors KU208G. All lagu daabacay ay ku condenser iyo laambad iyakana ah, kaas oo la beddelo dhalaalayaa, u adeega karaa iney yihiin tilmaame xoog ah. sixitaanka macquulka ah - laga bilaabo 0% ilaa 100%.

Maqnaanshaha triac ama thyristor a nalalka lagu saleyn karaa KU202N. Tani waa qalab aad caadi u ah isagoo hannaanka ah facooda ah. Iyada oo ay la isticmaalo in la soo ururay oo kartaa circuit ka hawlgala kala duwan oo xoog 50% si ay u 99%.

core Ferrite ka xadhig computer waxaa loo isticmaali karaa in la sameeyo loop a in abaalmarin faragelinta suurto galka ah ee bedesheen triac ama thyristor.

tilmaame scaler

eeg jaangooyaha awood dial kabida lagu daro kartaa raaxo weyn marka la isticmaalayo. waxaa SNAP samee. qalabka jir ah oo aan la adeegsan audio caawin karaan raadinta xubno sida. Qalabka sahlan looga heli karo suuqyada maxaliga ah ee magaalo kasta. Waa hagaag, haddii mid ka mid ah sida la guriga waxba samayn.

Tusaale ahaan, fekero suuragalnimada ah biiriyo jaangooyaha amar ay tilmaame kabida M68501 arrow iyo calaamadaha tiro, kaas oo la dhigay in ka rikoorrada Soviet jir ah. goob Feature waa doorashada ee resistor R4. Waxa hubaal ah u leeyihiin in ay qaado unugga R3 lagu daro, haddii tilmaame kale waxaa loo isticmaalaa. dheelitirka An ku habboon waa in la arkay at resistors awood yar yahay, kabida. Xaqiiqada ah in tilmaame fallaadhiina waxay muujiyaan karaa hoos u xoog by 10-20% ee birta isticmaalka dhabta ah kabida, 50%, i.e. ka yar ka badan kala badh.

gunaanad

control Power waayo, kabida la qaadi karaa, hanuuniyey by set ee tilmaamaha iyo articles la tusaalooyinka aan kor ku ah wareeggeedii kala duwan ee suurtogalka ah. From Alxan wanaagsan, ka daadanayo iyo heerkulka of tayada kabida element kululaynta inta badan ku xiran tahay. qalabka casri ah si loo xasiliyo ama dioska- isdhexgalka hoose waxaa loo isticmaali karaa in shirkii reer qalabka lagama maarmaanka u ah ayaa nidaaminaya danab soo socda.

aaladaha noocan oo kale ah hubkaas ayaa loo isticmaalaa si loo yareeyo iyo in la kordhiyo awoodda bixisey in element kululaynta birta, kabida, in kala duwan ee ka soo 0% in ay 141%. Waa arrin aad u sahlan. Waxaa jira fursad dhab ah in ay ka shaqeeyaan at voltages hoos 220 V. In suuqa maanta helitaanka gaadiidka tayada, qalabaysan gacanta ku gaar ah. qalabka Factory shaqeeyaan oo kaliya at awood hoos. jaangooyaha tallaabo-up wuxuu yeelan doonaa in aad iskaaga u ururiyaan.
