Wadnaha moduleka sahayda tamarta beddelka - beddelka beddelka

Falanqaynta beddelka korontadda beddelka-sare ee soo noqnoqda

Alaabta elegtarooniga ah ee aan la xiriirno maalin walba, waxaan ka heli karnaa tiro badanxudunta magneticqaybaha, kuwaas oo ay ku jiraan wadnaha eewareejinta korontadamodule - kabeddelka beddelka. Maalmahan, alaabooyinka elektaroonigga ah ee nolosha waxay leeyihiin shuruudo aad u adag oo ku saabsan muuqaalka alaabooyinka aadka u yaryar iyo kuwa aadka u dhuuban. Sida wadnaha isha tamarta ee alaabooyinkan elektiroonigga ah, sahayda korantada ee isbeddelka sare waxay leedahay faa'iidooyinka waxtarka sare, heerkulka wanaagsan iyo cabbirka yar. Sidaa darteed, alaabooyin badan oo elektiroonig ah ayaa ah sahay koronto beddelasho joogto ah. Xirfadlayaasha warshadaha elektaroonigga ah, waa inaad wax ka ogaataa beddelka sahayda beddelka.

Transformer-ku waa aalad adeegsata mabda'a induction electromagnetic si uu u beddelo hadda. Qaybaha ugu muhiimsan waxaa ka mid ahgariiradda hoose, gariiradda sareiyoxudunta birta.

Xirfadda elektiroonigga ah, transformers ayaa badanaa la arki karaa. Isticmaalka ugu badan waa moduleka sahayda korantada sida beddelka korantada iyo go'doominta:

①: Isbeddelku waxa loo qaybin karaa laba nooc: kor u kac iyo hoos u dhac. Inta badan sahayda korontadu way hoos u dhacday. Alaabooyinka elegtarooniga ah ee noocan oo kale ah ayaa inta badan loo isticmaalaa sahayda korantada miiska, adabtarada laptop-ka, dabaysha teleefanada gacanta, sahayda korontada TV-ga, makiinada bariiska, talaajadaha, mishiinada korontada, qalabka korontada, iwm. si loo helo koronto-sare oo DC ah.

②: Kobcinta guud ahaan waxaa loo isticmaalaa sahayda korontada rogayaasha ama khadadka DC-DC, oo leh sahay koronto degdeg ah, iyo batteriga 12V waxaa loo rogaa soosaarka 220V ee qalabka korontada.

③: Go'doomintaTransformers beddelashada-soo noqnoqda sarewaa shuruud badbaado si loo hubiyo badbaadada qalabka korantada. Marka AC la geliyo, transformer-ku waa inuu lahaadaa fogaan badbaado leh si loo gaaro go'doomin u dhexeeya gelinta AC aasaasiga ah iyo sahayda labaad ee korontada. Dabaysha aasaasiga ah ee taransfooriyuhu waxa ay ku go'doonsan tahay cajalad dahaadh ah, dhinacyada aasaasiga ah iyo kuwa sare ee qalfoofka ayaa go'doonsan. AC waxay soo dhex martaa jidhka bini'aadamka oo waxay samaysaa wareeg la socota dhulka, taas oo keeneysa khatar ku wajahan bini'aadamka. Waxaa jira tijaabooyin koronto-sare ah oo ku saabsan transformers, guud ahaan waxay u baahan yihiin 3KV.

Xidhiidhka hadda ka dhexeeya gariiradda aasaasiga ah iyo gariiradda sare:

Marka taransfooriyuhu uu ku socdo culays, isbeddelka hadda gariiradda sare waxa uu keeni doonaa isbeddel u dhigma hadda gariiradda hoose. Marka loo eego mabda'a isu-dheellitirka awoodda magnetic, waxaa laga soo saaray in hadda gariiradda hoose iyo tan sareba ay u dhigmato tirada wareegyada gariiradda. Hadda ka dhanka ah oo leh wareegyo badan ayaa ka yar, kan hadda jira ee dhinaca oo leh wareegyo yar ayaa ka weyn.

Waxa lagu qeexi karaa qaacidooyinka soo socda: gariiradda hoose ee hadda jirta/secondary coil current = gariiradda labaad oo rogan/rogmado gariiradda hoose.

Qalabka gariiradda ee transformer-ka waxaa ka mid ahsilig dahaaran, silig dahaaran oo saddex lakab ah, bireed naxaas ahiyoxaashi naxaas ah. Siligga la dahaadhay guud ahaan waxa uu isticmaalaa silig qalloocan oo badan. Faa'iidada siligga maroojinsan ee badan ayaa ah in laga fogaado saameynta maqaarka ee fiilada naxaasta ah, laakiin silig qalloocan oo badan ayaa sababi kara buuq. Silig dahaaran oo saddex-lakab ah ayaa loo istcimaalaa transformers oo aan ku filnayn masaafada badbaadada amaqalfoof yaraagga, iyo xaashida naxaasta ah iyo xaashida naxaasta ah ayaa loo isticmaalaa beddelaadaha awoodda sare leh.

Habka dabaysha ee gariiradda ayaa wanaajin karta EMI-ga beddelka, gaar ahaan sahayda korantada ee dib-u-celinta tamarta yar. Dabaylaha gariiradda iyo gaashaanka ayaa aad muhiim ugu ah EMI. Dabaysha gariiradda ayaa saamaysa qulqulka qulqulka iyo awoodda dulin ee beddelka, waxayna saamayn ku leedahay luminta beddelka.

 

Farqiga u dhexeeyaTransformers-ka hooseeyaiyoTransformers-soo noqnoqda sare:

① Transformer inta jeer ee shaqaynaysa
Sida laga soo xigtaysoo noqnoqoshada hawleed kala duwan ee Transformer, guud ahaan waxa loo qaybin karaa transformers-ka-soo noqnoqda yar-yar iyo Transformers-sare-sare. Tusaale ahaan, nolol maalmeedka, inta jeer ee celceliska warshadaha AC waa 50Hz, waxaanan ugu yeernaa beddelka ka shaqeeya inta jeer een is beddelka-soo noqnoqda hooseeya; halka inta jeer ee uu shaqaynayo transformer-ka-soo noqnoqda sare uu gaadhi karo tobanaan KHz ilaa boqolaal KHz. Transformers-ka-soo-celinta-soo-celinta-yar-yar iyo Transformers-ka-soo-celinta-sare ee awoodda wax-soo-saarka ah ee isku midka ah,mugga beddelka-soo-celinta-sare ayaa aad uga yar kan beddelka-soo-celinta-yar-yar. Transformer-ku waa qayb weyn oo ka mid ah wareegga sahayda korontada. Si loo hubiyo awoodda wax-soo-saarka iyadoo la dhimayo mugga, waa in la isticmaalo beddelka-soo-celinta-sare ee soo noqnoqda, sidaas awgeed koronto-sare-sare ayaa loo isticmaalaa sahayda beddelka.

② Mabda'a shaqada ee Transformer
Mabda'a shaqada ee is beddelka-soo noqnoqda sare iyo beddelka-soo noqnoqda hooseeya waa isku mid. Labaduba waxay ku shaqeeyaan mabda'a soo-saarka elektromagnetic-ka, laakiin marka la eego agabka wax-soo-saarka, agabka loo isticmaalo xudduntoodu way kala duwan yihiin. Xudunta birta ah ee transformer-ka yar-yar ayaa guud ahaan laga sameeyay go'yaal badan oo silikoon ah oo la isku dhejiyay, halka udub dhexaadka birta ee beddelka-soo noqnoqda sare uu ka samaysan yahay walxo bir ah oo sarreeya.

③ Calaamadaha gudbinta Transformer
Xadhkaha korantada ee DC-ga ee xasiloon, beddelka-soo-celinta-soo noqnoqda ee hooseeya waxa uu gudbiyaa calaamada hirarka sinaha. Marka lagu jiro wareegga sahayda korontadu, beddelka-soo-celinta-sare wuxuu gudbiyaa calaamadda mowjadda labajibbaaran ee garaaca wadnaha-sare.

Shaqooyinka ugu muhiimsan ee is-beddelka waa: beddelka tamarta; beddelidda impedance; karantiil; xasilinta danab (transformer saturation magnet), iwm Mabda'a beddelka waa mid fudud. Marka loo eego munaasabadaha isticmaalka kala duwan iyo isticmaalka kala duwan, habka dabaysha ee transformerku wuxuu yeelan doonaa shuruudo kala duwan.
