Sharaxaad Gaaban:


Faahfaahinta Alaabta

Marka looxa wareegga la iibiyo, hubinta in guddiga wareeggu uu si caadi ah u shaqeyn karo, inta badan si toos ah uma siin korontada, laakiin raac tallaabooyinka

hoos:

1. In xidhiidhku sax yahay.

2. Haddii korontadu ay gaaban tahay.

3. Xaaladda rakibida ee qaybaha.

4. Samee imtixaanada wareegga furan iyo wareegga gaaban marka horesi loo hubiyo in aysan jiri doonin wareeg gaaban ka dibdaaran.Tijaabada korontadu waxay bilaaban kartaa oo kaliya ka dib tijaabada qalabka koreka hor inta aan la dhamaystirin korontada.

Shaqooyin kale oo ku saabsan cilladaha wareegga elektarooniga ah

1. Go'aami barta imtixaanka

2. Deji kursiga shaqada ee qaladka

3. Dooro qalabka wax lagu cabbiro

4. Isku xigxiga qaladka

5. Cilad guud

Ogaanshaha awoodda

1. Awood-fiirinta

2. Dejinta joogtada ah

3. Qalabaynta firfircoon

Inta lagu jiro habka wax-ka-hortagga, waxaa lagama maarmaan ah in si taxadar leh loo eego oo loo falanqeeyo dhacdooyinka tijaabada ah oo la sameeyo diiwaanno si loo hubiyo daacadnimada iyo kalsoonida xogta tijaabada.

Arrimaha u baahan in fiiro gaar ah loo yeesho qaladka wareegga

Haddii natiijada khaladku sax tahay waxa si weyn u saameeya haddii mugga imtixaanku sax yahay iyo in kale iyo saxnaanta tijaabada.Si loo xaqiijiyo natiijada imtixaanka, waa in qaladka imtixaanka la dhimo iyo imtixaanka

Si aad u tijaabiso saxnaanta, waxaad u baahan tahay inaad fiiro gaar ah u yeelato qodobbada soo socda:

1. Si sax ah u isticmaal terminalka dhulka ee qalabka tijaabada

2. Cidhiidhiga soo gelida qalabka loo isticmaalo in lagu cabbiro korantada waa in uu aad uga weyn yahay ka-hortagga u dhigma ee goobta la cabbiray.

3. Baaxadda qalabka tijaabada waa in uu ka weyn yahay xajmiga wareegga wareegga tijaabada.

4. Si sax ah u dooro barta imtixaanka

5. Habka cabbirku waa inuu noqdaa mid ku habboon oo macquul ah

6. Inta lagu jiro habka wax-ka-beddelidda, kaliya maaha inay si taxadar leh u fiirsato oo cabbirto, laakiin sidoo kale waa inay ku fiican tahay duubista

 

Cilad-sheegid inta lagu jiro cilad-bixinta

Si taxaddar leh u raadi sababta cilladda, oo waligaa ha ka saarin khadka oo dib u rakib mar haddii cilladda la xallin kari waayo.Sababtoo ah haddii ay tahay dhibaato mabda'a, lama xallin doono xitaa haddii aad dib u rakibto

 

Dhib.

1. Habka guud ee baaritaanka qaladka

2. ifafaale guul darro iyo sabab guul darro

1) ifafaale guul darro caadi ah: wareegga cod-weynuhu ma laha calaamad wax gelin ah laakiin qaab-dhismeedka wax-soo-saarka

2) Sababta fashilka: badeecada la dhammeeyay waxay ku guuldareysataa ka dib isticmaalka muddada, taas oo laga yaabo inay sabab u tahay dhaawaca qaybaha, wareegga gaaban ama wareegga furan ee xiriirka, ama isbeddelka xaaladaha, iwm.

3. Habka guud ee lagu hubinayo fashilka

1) Habka indho-indheynta tooska ah: Hubi in xulashada iyo isticmaalka qalabku ay sax yihiin, haddii heerka korantada korantada iyo polarity ay buuxinayaan shuruudaha;haddii biinanka ka kooban polarity ay si sax ah ugu xiran yihiin,

Haddii uu jiro xiriir khaldan, xiriir maqan ama isku dhac labada dhinac ah.Haddii siliggu macquul yahay;haddii looxa daabacan yahay mid gaaban oo wareeg ah, hadday iska caabiyeyaasha iyo capacitors gubteen ama ha dilaaceen.Qaybaha indho-indheynta awoodda ayaa leh

Ma jiro kulayl, sigaar cabbin, udgoon gubanaya beddelka, haddii fiilada tuubada elektaroonigga ah iyo tuubada oscilloscope ay shidantahay, haddii uu jiro dab-demiye sare, iwm.

2) Hubi goobta hawlgalka ee static multimeter ah: nidaamka sahayda korontada ee wareegga elektarooniga ah, heerka hawlgalka DC ee transistor semiconductor iyo block isku dhafan (oo ay ku jiraan qaybaha, biinanka qalabka, danab koronto), qiimaha iska caabin ah ee wareegga, iwm .waxaa lagu qiyaasi karaa multimeter.Marka qiimaha la cabbiray uu si weyn uga duwan yahay qiimaha caadiga ah, cilladda waxaa la heli karaa falanqaynta ka dib.

Jid ahaan, goobta hawlgalka ee joogtada ah ayaa sidoo kale lagu cabbiri karaa oscilloscope "DC" habka gelinta.Faa'iidada isticmaalka oscilloscope waa in iska caabbinta guduhu ay sarreeyso, iyo heerka shaqada ee DC iyo qaabka hirarka calaamada ee barta cabbirka iyo calaamadda faragelinta suurtagalka ah iyo korantada qaylada ayaa aad ugu habboon falanqaynta khaladka.

3) Habka raadraaca isha: Wareegyo kala duwan oo kakan, calaamad baaxad gaar ah iyo soo noqnoqosho munaasib ah ayaa lagu xidhi karaa dhamaadka gelinta (tusaale, amplifiers heerar badan ah.
