Qaabka Caadiga ah ee Hadda: Lammaane calaamado ah (ama buuq) leh cabbir isku mid ah iyo jihada labada xariiq ee calaamadaha kala duwan. In wareegga. Guud ahaan, buuqa dhulka guud ahaan waxaa lagu kala qaadaa qaabka caadiga ah hadda, sidaas darteed waxa kale oo loo yaqaan qaylada qaabka caadiga ah.
Waxaa jira habab badan oo lagu xakameeyo buuqa-habka caadiga ah. Marka lagu daro dhimista qaylada caadiga ah ee ka imanaysa isha, habka ugu badan ee loo isticmaalo xakamaynta qaylada caadiga ah waa in la isticmaalo inductor-ka caadiga ah si loo shaandheeyo qaylada caadiga ah, taas oo ah, si loo xakameeyo qaylada caadiga ah ee bartilmaameedka. wareegga. . Taasi waa, aaladda hab caadi ah ee ceejinta ayaa si taxane ah ugu xiran khadka. Ujeedada tani waa in la kordhiyo xannibaadda loop-ka caadiga ah si habka caadiga ah ee hadda jira uu u kala daadiyo oo u xannibo (oo ka tarjumayo) choke, si loo xakameeyo qaylada caadiga ah ee khadka.
Mabaadi'da Habka Caadiga ah ee Chokes ama Inductors
Haddii labada gariirood ee isku jihada ah ay ku dhaawacmaan giraanta birlabeedka ee ka sameysan shay birlabeed gaar ah, marka is beddelka hadda uu dhex maro, qulqulka birlabeedka ayaa ka abuurma gariiradaha iyadoo ay ugu wacan tahay kicinta korantada. Calaamadaha qaabka kala duwan, qulqulka magnetic-ka ee la soo saaray ayaa isku mid ah oo ka soo horjeeda jihada, wayna tirtiraan midba midka kale, sidaa daraadeed habka kala duwanaansho ee uu keeno giraanta magnetic waa mid aad u yar; halka calaamadaha habka caadiga ah, baaxadda iyo jihada qulqulka magnetic abuuraa ay isku mid yihiin, labadooduna midba midka kale ayaa kor u qaadaya. Giraanta birlabeedka ayaa leh cillad caadi ah oo weyn. Habkani waxa uu ka dhigayaa inductor-ka caadiga ah in uu yaraado raad-reebka calaamada habka kala duwan waxana uu leeyahay waxqabad shaandhayn wanaagsan oo loogu talagalay qaylada qaabka caadiga ah.
(1) Habka kala duwanaanshaha hadda wuxuu dhex maraa gariiradda qaabka caadiga ah, jihada xadhkaha magnetic waa ka soo horjeeda, goobta magnetic-ka ee la kiciyay waa la daciifiyay. Waxaa laga arki karaa jihada xariiqyada magnetic ee jaantuskan soo socda - falaarta adag waxay muujinaysaa jihada hadda, iyo xariiqda dhibcaha ah waxay muujinaysaa jihada magnetic field.
(2) Habka caadiga ah ee hadda socda wuxuu dhex maraa gariiradda qaabka caadiga ah, jihada xariiqyada magnetic field waa isku mid, goobta magnetic-ka ee la kiciyay waa la xoojiyay. Waxaa laga arki karaa jihada xariiqyada magnetic ee jaantuskan soo socda - falaarta adag waxay muujinaysaa jihada hadda, iyo xariiqda dhibcaha waxay muujinaysaa jihada magnetic.
Inductance ee gariiradda qaabka caadiga ah waxaa sidoo kale loo yaqaan isku-dhafan is-wax-qabad. Waxaan ognahay in inductance-ku uu yahay awoodda lagu dhalin karo dhul-magnetic. Qaabka caadiga ah ee gariiradda ama inductance-ka caadiga ah, marka habka caadiga ah ee hadda socda uu dhex maro gariiradda, maadaama jihada khadadka magnetic field ay isku mid yihiin, inductance-ka dareeraha looma tixgeliyo. Xaaladda , qulqulka magnetic waa la kor saaray, iyo mabda'a waa inductance labada dhinac. Xadhkaha magnetic field-ka ee uu dhaliyo gariiradda cas ee sawirka hoose waxa ay dhex maraan gariiradda buluugga ah, xadhkaha magnetic field-ka ee ay abuurto gariiradda buluuga ah waxa ay sidoo kale sii maraan gariiradda cas oo ay midba midka kale soo jiidato.
Marka loo eego aragtida inductance, inductance sidoo kale waa la labanlaabmaa, isku xidhka qulqulku wuxuu u taagan yahay wadarta qulqulka magnetic. Inductors-ka caadiga ah, marka qulqulka magnetic labanlaabmayo asalka, tirada wareegyadu isma beddelaan, kan hadda jirana waxba ma beddelo, ka dib waxay la macno tahay in Sida inductance la kordhiyo 2 jeer, waxay ka dhigan tahay in u dhiganta magnetic permeability waa. labanlaabmay.
Waa maxay sababta daalacashada magnetic u dhiganta loo labanlaabay? Laga soo bilaabo qaacidada inductance ee soo socota, maadaama tirada wareegyada N aysan isbeddelin, wareegga magnetic iyo aagga is-goysyada ee xudunta magnetic waxaa lagu go'aamiyaa cabbirka jireed ee xudunta magnetic, sidaa darteed ma isbeddelo, kaliya shay waa daalacashada magnetic. u waa labanlaabmay, sidaas darteed qulqulka birlabeedka ayaa la abuuri karaa
Sidaa darteed, marka habka caadiga ah ee hadda uu marayo, habka caadiga ah ee inductance wuxuu ku shaqeeyaa habka isdhexgalka. Marka la eego ficilka isdhexgalka wadajirka ah, inductance u dhiganta ayaa lagu kordhiyaa kharashka, sidaas awgeed habka caadiga ah ee caadiga ah ayaa labanlaabmi doona, sidaas darteed waxay saameyn wanaagsan ku leedahay calaamadda habka caadiga ah. Saamaynta shaandhaynta waa in la xannibo calaamadda habka caadiga ah oo leh xannibaad weyn oo ka hortag ah in ay ka gudubto inductor-ka caadiga ah, taas oo ah, si looga hortago in calaamadda loo gudbiyo marxaladda xigta ee wareegga. Kuwa soo socda waa falcelinta soo jiidashada leh ee ZL ee uu dhaliyo inductor.
Si aad u fahamto inductance ee inductor-ka caadiga ah ee habka caadiga ah, tilmaanta ugu weyn waa in la fahmo inductance wadajir ah, dhammaan qaybaha magnetic, iyada oo aan loo eegin waxa magaca uu yahay, ilaa iyo inta aad fahamto qaabka isbeddelka ee goobta magnetic oo aad aragto dabeecadda magnetic field is beddelo iyada oo loo marayo ifafaale, waxa ay noqon doontaa mid fudud in la fahmo, ka dibna waa in aan had iyo jeer qabsan line field magnetic, taas oo ah qaabka dareen ee fahamka garoonka magnetic. Bal qiyaas in iyada oo aan loo eegin fikradda isla magaca ama magaca kala duwan ama isdhexgalka labada dhinac ama ifafaale field magnetic, waxaan had iyo jeer sawiraa xariiqda magnetic field si aan u ogaanno iyaga - u yaqaan "usha magnetka" ee hore loo sharaxay. Habka dabaysha”.
