Gaabiyo: nidaamka iyo qalab. Switches la dimmers

kantaroolka gaarka ah waxaa loo isticmaalaa si ay ula qabsadaan dhalaalka laambadihii incandescent. Qalabka Kuwan waxaa sidoo kale loo yaqaannaa dimmers. Waxay ka jira versions kala duwan, iyo, haddii loo baahdo, in dukaanka aad had iyo jeer dooran kartaa model ku haboon. Asal ahaan, waxay bedeli breaker in laambad incandescent ah a. beddelid ugu fudud waxaa ka mid ah xakamaysada ah Rotary qalin. Marka dejinta luminance isbedelka dheeraad ah ka kooban ee isticmaalka korontada.

Haddii aad soo xusuustaa wakhtigii jir ah, gacanta ku ah ee la qabsado dhalaalka looma isticmaalo. Halkii, dimmers gaar ah lagu rakibay. Iyada oo ay caawimo, sidoo kale waxaa laguu xakameyn karaa nalalka dhaadheer. Guud ahaan, iyadoo waajibaadka ay si fiican u niyad jabka, laakiin waxay lahaayeen hal qasaaro. Waxay ku xiran yahay isticmaalka korontada. Sida hore u soo sheegnay, xakameeya casriga ah ku bixiya korontada ka yar haddii aan isticmaalo awoodda buuxda. In the case of resistances xukunka oo aan ka codsan. Awoodda ugu yaraan baabbi'iyey korontada iyo sidoo kale ugu badnaan ah. Xad-dhaaf ah ay dhacdo in this diinta kulaylka.

Scheme jaangooyaha caadiga ah

circuit Simple gaabiyo ku lug leedahay isticmaalka nooca potentiometer toosan, oo labo ka mid ah transistors oo xoog ku yar yahay. Si loo xakameeyo capacitors hirka sare waxaa loo isticmaalaa in nidaamka. diirkja ee aaladaha noocan ah u baahan ferrite nooca kaliya. Isla markiiba ka hor terminal ayaa lagu wadaa in thyristor ku diode Shockley.

Sidee inuu ka soo leexdo dial si ilayska?

Laambad miiska la gaabiyo sida caadiga ah la shaqeeyay, hubi danab oo dhan Semiconductor ah. Taas waxaa la samayn karaa iyadoo la isticmaalayo ahaatid caadiga ah. Next, baadho nalka guddiga. Haddii la dhigay nooca odnokalnogo, oo dhan ayuu sameeyey arrin fudud. semiconductors The saarka muhiim ugu xiran outlet furan, taas oo uu leeyahay polarity xun. Xaaladdan oo kale iska caabin ah ugu badan waa in ay ahaadaan 3 ohms. Si ay u tijaabiso qalabka, waa in aad isku shaandheyn xakamaysada iyo daawado waqti isku mid ah loogu talagalay dhalaalka laambadihii incandescent.

Ku xiridda riixaaya button in laambadda

Si loo xakameeyo dhalaalka laambadihii incandescent si fiican u shaqeeyaan, waxaa muhiim ah in aqoon loo yeesho maamulka qalabka. Next, waxaad u baahan tahay in lagu xiro oo dhan aad la xiriirto. Haddii circuit loo isticmaalo a multi-channel, danab ku it on loo hubiyo inaad ahaatid. si toos ah xarunta xiriirada qaadeen brazing. Waxaa muhiim ah waqti isku mid ah inta lagu jiro hawlgalka ma yeeli resistors. Intaa waxaa dheer, aad u baahan tahay in ay is ogow of ningax xarkaha. Ka hor jeestay on dirato aad rabto in aad si aad u hubiso oo dhan ayaa la aamin ah. Ka dib markii korontada ee loo baahan yahay in ay isku dayaan in la beddelo dhalaalka adigoo riixaya badhanka.

gacanta ku soo dhalaasho Sare

iftiiminta a high-voltage gaabiyo, sida caadiga ah, waxaa laga heli karaa tiyaatarada. laambadihii incandescent Waxaa loo isticmaalaa ilaa xad awood badan, iyo qalabka waa in ay noqdaan si ay u adkeysan xamuulka culus awoodaan. Triacs ujeedadaas, a high-voltage (la KU202 calaamadeeyay) codsato. transistors-cirifoodka waxaa loo isticmaalaa, si kastaba ha ahaatee, ka beddelka caadiga ah oo dhanba ayaa sidoo kale dhigay.

buundooyinka Diode soldered dhow thyristors iyo lagama maarmaan u ah gudbinta seenyaalaha dhakhso ah. dioska- Zener inta badan waxaa laga heli karaa D814 wayn. Waxay yihiin dukaanka waa qaali, waana in this la tixgeliyo. resistors variable in nidaamka waa in ay u adkeysan xadka danab 60 ohms awoodaan. Wakhtigan, dhigooda caadiga dhisnayd la ohms kaliya 5.

Lagu daydo la resistors sax

Gaabiyo la resistors noocan ah waxaa loogu talagalay awood celcelis incandescent. dioska- Zener kiiskan, 12 V resistors Doorsoome nidaamiyo waa dhif iyo naadir. beddelka inta jeer Low ayaa loo isticmaali karaa. Si loo kordhiyo Wehliyaha conductivity kiiskan ay suurto gal tahay iyadoo la kordhinayo tirada capacitors. Waayo, triac waa in ay in lagu meeleeyaa lammaane. Xaaladdan oo kale, khasaaraha kulaylka noqon doonaa yar. network iska caabin xun inta badan waa dhibaato halis ah. Dollar ugu dambeyntii keenta in burburka of diode zener ah. capacitors Electrolytic la low-soo noqnoqoshada qaylada qabsadaan ilaa xad si guul leh. Waxa ugu weyn ee la this - ma siiyo danab sare fiiqan in laambadda.

Bannaanka jaangooyaha la resistors vysokomegaomnymi

control dhalaalka noocan ah waxaa loo isticmaali karaa si loo xakameeyo noocyada kala duwan ee laambadihii. Qorshaha waxaa vysokomegaomnye ka kooban resistors AC, iyo sidoo kale zener caadiga ah. Thyristor kiiskan ayaa lagu wadaa in ay soo socda condenser ah. Si loo yareeyo ku takhasusay xadka inta jeer inta badan isticmaalaan Fiyuus nooca. Waxay ka adkaan karin load a of 4 A. At inta jeer xadka this ee wax soo saarka waxay noqon doontaa ugu badnaan 50 Hz awoodaan. Triacs Ujeedada guud ee danab aqbasho adkeysan karaan at 15 V.

Switches la nidaamiyo FET

Iyada oo daaro gaabiyo on FET lagu gartaa difaaca wanaagsan. Short-circuit nidaamka dhacaan aad u dhif ah, iyo waxa ay dhab ahaan waa faa'iido. Intaa waxaa dheer, fadlan ogow in jaangooyaha Zener waxaa loo isticmaali karaa oo keliya KU202 sixitaanka. Xaaladdan oo kale, waxay awood u hawlgala la resistors noqnoqoshada hooseeyo iyo la qabsadaan faragelinta si fiican. Triacs in wareeggeedii ku yaal dambeeya resistors ah. iska caabin ah ayaa xadidaysa in nidaamka waxaa ku waajib ah in la dhowro 4 ohms. danab ee resistors aqbasho qaban qiyaastii 18 xadka V. noqnoqoshada, markeeda, waa in aan ka badnayn 14 Hz.

Jaangooyaha la trimmer

Gaabiyo la capacitor trimmer si guul loo isticmaali karaa si ay ula qabsadaan xoogga nalalka dhaadheer. Switches kiiskan waa in lagu meeleeyaa dambeeya buundada diode ah. dioska- Zener wareegi loo baahan yahay xakamaynta faragelin. Resistors nooca variable waxaa inta badan impedance ku yareysey la hayo at 6 ohms.

Marka thyristors this waxaa loo isticmaalaa si gaar ah si ay u ilaaliyaan danab ee heer habboon. Triacs laftiisa iyada oo awood u marayo haatan si heer ah oo ku saabsan 4 A. ilaaliyaal nooca Fiyuus waa dhif iyo naadir. Dhibaatada qalabka sida ee conductivity korontada waxaa lagu gaarayaa by yahay ee resistor ka variable ugu wax soo saarka.

Model la triac fudud

iftiinka gaabiyo la thyristor fudud waa haboon daydo riix-button. nidaamka ilaalinta, sida caadiga ah, ma aha. Dhammaan xiriirada in jaangooyaha waxaa lagu sameeyey oo ah naxaas. iska caabin ah ugu badnaan in thyristor caadiga adkeysan karaan tubada 10 V. Waayo ilaaliyaal Rotary si liidata ku habboon. resistors sax la nidaamiyo sida aan awooda inay shaqeeyaan. Tan waxa u sabab ah heerka sare ee iska caabin xun ee Bannaanka.

resistors High-noqnoqoshada sidoo kale arrin naadir ah. Xaaladdan oo kale, heerka qaylada noqon doonaa weyn iyo waxay keeni doontaa in dollar ah diode zener ah. Haddii aan ka hadlo laambadihii miiska caadiga ah, waxaa fiican in la isticmaalo labo caadiga thyristor la resistors silig. tabinta ay yihiin heer sare si caddaalad ah. Waana dhif kululaado, dhereg awoodda celcelis ahaan waa qiyaastii 2 watts.

Isticmaalka capacitors variable in Bannaanka

Iyada oo la adeegsanayo capacitors variable ku guulaystay isbedel siman dhalaalkii laambadihii incandescent. Xaaladdan oo kale, ku dayashada electrolytic shaqeeyaan arrin ka duwan. Transistors for capacitors kuwani waa ku haboon yahay 12 watts ugu. danab la gelin waa in la dayactiray 19 V. Waxaa sidoo kale waa in ay bixiyaan isticmaalka fiyuusyada. Thyristors waxaa guud ahaan loo isticmaalo la sixitaanka KU202. Waxay si fiican u aduu versions Rotary. Si loo kordhiyo potentiometers Wehliyaha conductivity loo isticmaalo la shido network.

unijunction xakamaysada qalabka

Unijunction iftiin gaabiyo loo yaqaan for halleeyo lillaahinimada. Resistors waxa ku jira, sida caadiga ah, loo isticmaalo by 4 watts. Xaaladdan oo kale, danab ugu badan waa ay awoodaan in ay qabtaan at 14 V. Marka la isticmaalayo, waxaa muhiim ah in ay ku haay maanka in nuurka ayaa laga yaabaa in flicker. fiyuusyada The hindiseen waxaa loo isticmaalaa ilaa xad dhif ah.

Ugu badnaan lagu qiimeeyo talooyinka hadda ka tagi karo 4 nooca A. Thyristors KU202 awood nidaamka noocan oo kale ah in ay ka shaqeeyaan oo kaliya laba la buundada diode ah. qalab triac waa in la xiran in ka badan resistor ah. In ay ku xidhmaan gaabiyo si laambadda, waxaad u baahan tahay si aad u nadiifiso dhammaan xiriirada. guryaha ee qalabka waxaa muhiim ah in aad dalbato dielectric ah. Xaaladdan oo kale, ammaanka shaqada la damaanad doonaa.
