Scheme kordhiyo tube. Jaantuska xarkaha ee kordhiyo ah

Maqaalkani waxa la bartay doono tuubooyinka vacuum circuit kordhiyo si faahfaahsan. Dabcan, farsamadaa waxa ay tahay dhacsan, laakiin ilaa maantadan la joogo waxaad kula kulmi kartaa taageerayaasha "Retro". Qof kaliya door bidaan dhawaaqa tube digital, oo qof ayaa ku hawlan in ay tahay siinaya nolosha labaad, oo duqoobay, waxaa dib u soo celisa qayb by yara. ka shaqeeya badan oo radio hiwaayadda, kuwaas oo ka shaqeeya hawada, ay isticmaalaan laambad ee dhismaha qaar ka mid ah Cascades qorsheyaasha. Tusaale ahaan, UHF u fududahay in ay si hufan u dhisaan on laambadihii awood badan, tan iyo markii ay transistors la mid aad u adag doonaa.

circuit kordhiyo dhismayaasha

Jaantuska block waa sida soo socota:

1. Isha signal (saarka makarafoon, telefoonka, computer, iyo d sidaas on..).
2. gacanta mugga - potentiometer ah (resistor variable).
3. preamplifier waxaa dhisay on ilayska (sida caadiga ah transistor), transistor ah.
4. Silsilada Bannaanka gacanta ku oqoonsan xiran yahay laambad preamplifier anode ah.
5. kordhiyo Final. Waxaa badanaa lagu sameeyaa pentode ah, tusaale ahaan, 6P14S.
6. qalab ku habboon A, jidaynayey soo saarka ee nidaamka Gudoomiyaha kordhiyo iyo dekedda ah. Sida caadiga ah, xilkaan waxaa hoos u dhigay nooc transformer (220/12 Volt).
7. korontada, kuna waari dhexdeeda labada voltages ahbaa: joogta 250-300 V iyo 6.3 V ac (12.6 haddii loo baahdo).

Sida laga soo xigtay jaantuska block ah, dhisay mabda '. Waxaa lagama maarmaan ah in si fiican loo baaro nidaamka Guntin kasta soosaarka kordhiyo ayaa sababay dhibaatooyin.

LF Power kordhiyo

Sida kor ku xusan, korontada waa in uu soo saaro laba qiimaha danab kala duwan. Si arrintan loo sameeyo, u isticmaal transformer la design gaar ah. Waa in uu leeyahay saddex windings - Networking, Sare iyo Jaamacadaha. Labada dambe soo saari danab talantaalli ah 250-300 V iyo 6.3 V ah, siday u kala horreeyaan. 6.3 - danab sahayda of filaments tuubooyinka ah. Iyo haddii ay tahay, sida caadiga ah, uma baahna wax daaweyn ah, tusaale ahaan, in ka sifeynta iyo sixitaan, ee AC 250 Volts u baahan tahay in yar oo isbedel ah. Tan waxaa looga baahan yahay in ay ku xidhmaan circuit kordhiyo si ay il awoodeed ah.

Si aad u codsato block rectifier this, oo ka kooban afar dioska- Semiconductor iyo filtarrada - capacitors Electrolytic. Dioska- ogolaadaa toosi talantaalli ah hadda oo aad u joogto ah. capacitor A leeyahay feature xiiso leh. Haddii aad eegto capacitors circuit u dhiganta, waayo, AC iyo DC (by sharciga Kirchhoff ayaa), waxaad ka arki kartaa mid ka mid feature. In hawlgalka, impedance capacitor la bedelay ee wareeggeedii hadda joogto.

Laakiin marka ka hawlgala circuit AC waxa uu ku bedelay qeybta kaari ah. In si kale loo dhigo, marka lagu rakibay ee bangiga capacitor xoog ah waxaad ka heli doontaa a danab nadiif DC, oo dhan qayb ka variable baabi'i doontaa sabab u boosteejada circuited gaaban-in Bannaanka u dhigma.

Shuruudaha transformer ah

Xaalad muhiim ah - joogitaanka tirada loo baahan yahay ee windings for sahayda ee anodes iyo nalalka daah buuxieyey. Iyada oo ku xidhan oo circuit isticmaalaa kordhiyo xoog ah u baahan Daawatay xoog danab a kala duwan. qiimaha Standard - waa 6.3 V. Si kastaba ha ahaatee, qaar ka mid ah laambadihii, sida G-807, PG-50, waxay u baahan yihiin danab a of 12.6 V. taasi adkaynaysaa design iyo dhigaysa isticmaalka transformer size waaweyn.

Laakiin haddii aad damacdo inaad si ay u ururiyaan awoodda keliya laambadihii farta (6N2P, 6P14P et al.), Baahida loo qabo sida danab korontada ah aan la iftiimay. Fiiro gaar ah u size - haddii aad rabto si ay u ururiyaan kordhiyo yar, isticmaali a gudbiyeyaasha-hal gariiradda. Waxay leeyihiin hal khasaare - waa wax aan macquul aheyn in la helo awood sare. Haddii ay jirto su'aal ah awood, waxaa wanaagsan in la isticmaalo gudbiyeyaasha TS-180, TS-270.

Housing qalabka

Waayo, low-soo noqnoqoshada Sammeecado ku fiican yihiin in guryaha ka aluminium isticmaalo ama galvanized, ururinayo of radioelements soo saaro hab badh. Faa'iida qalabka ururinayo on board a wareeg daabacan - kulaylinta saldhig laambad lugaha bilaabaan inay delaminate kabida ka tareenka, waxaa la baabbi'iyey. Badiyay xiriir, oo aad shuqulkaaga oo Ulf noqotaa deganayn, waxaa jira dhawaaqyo kale.

Haddii ee pre-yada circuit kordhiyo waxaa laga codsadaa in transistor ah, waa ka xigmad loo sameeyo dhul yar oo PCB - wuxuu noqon doonaa more lagu kalsoonaan karo. Laakiin isticmaalka hybrid dhigaysa shuruudaha awood ay. Waxaa la diyaarin karaa in kiiska alwaax for kaban Ulf. Laakiin gudaha aad u baahan tahay si loo soo dajiyo jiifku bir ah, kaas oo lagu soo ururiyay doono qalabka oo dhan. Waxaa lagu talinayaa in aad dalbato sanduuqa battariga ee biraha, sida waxa ay taasi fududahay in la baadho Cascades midba midka kale ka, taas oo ay meesha suurtagalnimada ee is-excitation iyo faragelinta kale.

Dheellitir mugga iyo midab

circuit a kordhiyo fudud lagu daro karaa laba xeerarka - mugga iyo midab. jaangooyaha ugu horeeyay ee si toos ah dhajinta on tubada ah ee Ulf, waxay u saamaxdaa inuu wax ka beddelo qiimaha signal soo socda. Waxaad isticmaali kartaa resistors variable of design kasta oo si fiican u shaqayn doonaa in Ulf ah. Iyada oo ay gacanta ku oqoonsan sidoo kale dhibaatooyinka waa in aan dhicin - resistor a variable ka mid circuit anode ee Marxaladda koowaad ee. u baahan tahay oo keliya in lagu go'aamiyo in jihada rogista cajaladda la sameeyo si ay u dar RF ah, iyo waxa awoodda LF ah.

Waxaa lagu talinayaa in la sameeyo oo dhan ka Sammeecado warshadaha, haddii kale way adag tahay waxa uu noqon doonaa in ay isticmaalaan design ka. Laakiin waxa kaliya circuit gacanta ku oqoonsan, waxaa ka xigmad waa si loo soo dajiyo unit yar, kaas oo beddeli doona inta jeer ee aad u ballaaran. Sammeecado tube qorsheyaasha ku jiri kara modules yar on semiconductors - midab, filtarrada-pass hooseeyo. Haddii aanu jirin rabitaan in ay soo saaraan midab-naftaada, waxa laga iibsan karaa dukaamada. Qiimaha midab sida waa wax yar yahay.

kordhiyo rikoodh

Laakiin dhegaysiga rikoodh Ulf waa badan gooyeen badan Mono. Iyo in ay labo jeer sida adag ka dhigi - aad u baahan tahay si ay u ururiyaan Ulf kale la soo koobin isku. Sidaas darteed, waxaad ka heli laba gashiga iyo wax soo saarka badan. Oo circuit kordhiyo awoodda iyo marxaladaha hordhaca ah waa in ay ahaadaan isku mid ah, haddii kale wax qabadka kala duwan yihiin.

All capacitors iyo resistors ee xuduudaha la mid ah - oo ka mid ah qiimaha doorsoomayaasha iyo dulqaadka. shuruudaha gaarka ah ee iska caabin in la beddelo - waa in la isticmaalaa design xidhay for gacanta mugga, iyo midab ah. fikradda ah in ay lagama maarmaan tahay si loo hubiyo in midayso ee la qabsado oo xuduudaheedu waa kuwan labada channels.

nidaamka 2.1

Laakiin si loo hagaajiyo tayada codka, waxaad ku dari kartaa subwoofer in xoojin doonaa firikuwensiyada hooseeyo. Guud ahaan circuit xiriir kordhiyo aysan waxba ka beddelin, kaliya block saddexaad waxaa lagu darayaa. Dhab ahaantii, waa in aad haysataa saddex Sammeecado Mono gabi ahaanba isku mid - mid ka tegey channel, xaq, subwoofer.

Ogsoonow in gacanta mugga on subwoofer ah waa ka CFP goonida. Tani waxay u ogolaaneysaa in mustaqbalka in la beddelo heerka faa'iidada. Jar ka soo noqnoqoshada fuliyey circuit fudud, oo ay ku jiraan dhowr capacitors iyo resistors "dheeraad ah". Laakiin waxaad isticmaali kartaa filtarrada-pass yar yahay diyaar-dhigay, taas oo waxaa lagu gadaa dukaan wax ka mid ah qaybaha radio.

gunaanad

Waxaan ka baaray nidaamka of Sammeecado tube, kuwaas oo inta badan soo noqnoqda hams naqshadooda. iyaga Is-soosaarka hoos ciidanka of nin yaqaano sida loo maareeyo bir ah, kabida, iyo suugaanta farsamo. Laakiin haddii aadan kala saari karaa ka resistor iyo condenser ee ha isku dayin inay wax bartaan, oo u baahan kordhiyo ah, waxaa fiican inaad weydiiso sayidkiisa khibrad dhigi VLF ah.
