Repair of nalalka tamarta-badbaado si loo badbaadiyo

Sanadihii la soo dhaafay, qaar badan oo ka culus jiro bedelka ee nalalka caadiga ah iyo laambadaheedii keydinta tamarta. The saldhig u ah laambad dhaadheer yar oo cabbirkooda, kuwaas oo shaqo nidaam electronic ah keenaysay qalab joogto ah (waaya'aragnimo electronic, waaya'aragnimo electronic). laambadihii qaali ah ku tilmaamay bilow jilicsan oo ay maamulaan inta badan ka dheer, ficil ahaan muddada loogu balan qaadayo gudahood. Laakiin fursadaha qaaliga ah, iyo sidoo kale imitations ee wata magac oo caan ah ma qiil aaminay iyaga rajaynaynaa in hawlgalka muddo dheer oo ay si fudud u burburay. Marka la barbar dhigo caadiga ah nalalka incandescent qiimaha bedelay ay "guriga ka", iyo sidoo kale nalalka dhaadheer waa inta ka sareeya, sidaas dayactirka ee nalalka dhaadheer, iyo sidoo kale fursadaha tamarta lagu badbaadinayo, cudur daar si loo badbaadiyo. Ka dib markii dib u soo celinta ee ay caafimaad u baahan tahay si aad u iibsato laambadihii cusub loo baahnayn.

Sababta ugu badan ee failure waa dillaacin daah buuxieyey ama cillad ee dheelitirka sabab u ah burburka ee capacitor resonance ama transistor. Repair of nalalka tamarta lagu badbaadinayo ayaa suuragal ah keliya in ay dhacdo qalad waaya'aragnimo. Lamps la filaments gubo uma baahna in ay iska tuur. Waxay waxaa loo isticmaali karaa si ay ugu bedesho waaya'aragnimo haleysan laambadihii kale, haddii dunta ay yihiin si ka shaqeeya. Si kastaba ha ahaatee, mararka qaarkood waxaa suurtagal ah si uu u xaliyo muquuninta la gubo, ku dhow xoog iyada resistor sare (oo ku saabsan 25 W, 10 ohms) oo ay ka saareen diode boodo ku muquuninta this, haddii ay jirto. Laakiin inta badan dayactir u baahan yahay beddelo waaya'aragnimo electronic tamarta lagu badbaadinayo laambadihii. Waa in la bedelay mid si buuxda ama, at xirfad gaar ah, waxaad isku dayi kartaa bedelay qaybaha kaliya sii gudhaya.

Sababta saarka badbaado awood laambad failure wuxuu noqon karaa hab adag oo ay howlgal - at the goobaha heerkulka koronto gaadhaysa 60 degrees la'aan hawo (ee cap laambadda godad bay leeyihiin). Kulayl keenaysaa in dhula iyo dillaacin of filaments iyo failure ee xubno waaya'aragnimo ka. Dayactirka laambadihii keydinta tamarta laga yaabaa in loo baahdo haddii ay jiraan cilado dhismaha shirka lama filaan ah ama si ula kac ah si loo badbaadiyo. Gaar ahaan dembigan laambad Shiinaha. Si aan si la kulanaa "nadiifiya" gore- sida, aad u baahan tahay si ay u iibsadaan alaabta ee warshadaha caan ah. Tusaale ahaan, baahida loo qabo in la fuliyo dayactirka ee nalalka tamarta lagu badbaadinayo "Yooxanaa erayga Kosmos», «Fluminense bisha» iyo saarayaasha kale si fiican u yaqaan si dhab ah waxaa jira waxyaabo badan ka yar isagoo u hagaajinno dhigooda Shiinaha.

Yeereyso laambadihii keydinta tamarta aan si gaar ah u adag tahay, si kastaba ha ahaatee, in ay si taxadar leh u sameeyaan si aanay u jebin sibraarkii, waxaa aad u jilicsan. Waa in aynaan illoobin in gudaha sibraar ku leeyihiin mercury vapor waa khatar ku ah caafimaadka. Fur sanduuqa battariga ee waaya'aragnimo ee elektarooniga ah waxay noqon kartaa wax af (kaashawiito cidhiidhi ah), taas oo ay lagama maarmaan tahay si loo dabciyo xire ee isku xirta qaybaha caaga ah ee jirka. Markaas waxaad u baahan tahay inaad barkinta saarka spirals silig ka Bannaanka electronic. Waxaa weli guddiga elektaroonik ah, labada kirishbooyada xiran qayb ka mid ah jidhka, kaas oo Buur kartaa Soviet ah. Next, hubi in buuxieyey dhawrsan by qiyaaso iska caabin ah la ohmmeter ah. Haddii iska caabin aan la koobi karayn waxay muujinaysaa baaxadda dunta waa jabtay. Xaaladdan oo kale, sida hore u soo sheegnay, sibraar waxaa mar dambe ma ay codsatay. Qaybaha ugu nugul electronic ah Converter ah - C5 capacitors, C4, C3, waxay gabi doono marka dollar. Waxaa jira xaalado marka failure yimaado madan ama resistor low-caabin ah R1, waxaa lagama maarmaan ah in ay bixiyaan si ay u dayactirka nalalka tamarta lagu badbaadinayo la waaya'aragnimo dareenka darafkeeda. Waxa macno si loo hubiyo oo firfircoon qaybaha - transistors VT, dioska- VD1-VD4 buundada rectifier.

Digniin! Dhawraan xeerarka ammaanka korontada iyo in aan la fulin dayactir ah lam tamar-ku badbaado, anigoo aan lahayn xirfadaha qalab awood shaqada.
