Txoj Cai ntawm Transformers
Lub transformer yog ib qho khoom siv hluav taws xob uas siv lub hauv paus ntsiab lus ntawm electromagnetic induction los hloov voltage. Nws muaj ob los yog ntau tshaj ntawm windings qhwv ib ncig ntawm ib tug ntau yam hlau core. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab hluav taws xob tuaj yeem ua tiav hauv cov kauj ruam hauv qab no:
- Electromagnetic Induction: Thaum alternating tam sim no ntws los ntawm cov thawj winding (tseem hu ua thawj sab), nws generates ib tug hloov magnetic flux nyob rau hauv lub hlau core.
- Sib Nqus Flux Coupling: Qhov hloov magnetic flux kis tau los ntawm cov tub ntxhais hlau mus rau qhov thib ob winding (tseem hu ua lwm sab).
- Voltage Transformation: Raws li Faraday txoj cai ntawm electromagnetic induction, lub zog hluav taws xob (EMF) yog induced nyob rau hauv lub thib ob winding. Qhov loj ntawm EMF no yog proportional rau EMF nyob rau hauv thawj winding thiab qhov ratio ntawm tus naj npawb ntawm lem ntawm windings.
Transformers tuaj yeem yog ib zaug -theem lossis peb-theem, siv los nce lossis nqis qis qis, thiab tau siv dav hauv kev xa hluav taws xob, kev faib tawm, thiab ntau yam khoom siv hluav taws xob.
Txoj cai ntawm Asynchronous Motors
Lub cev muaj zog asynchronous (tseem hu ua induction lub cev muaj zog) yog ib qho khoom siv uas hloov hluav taws xob hluav taws xob rau hauv lub zog siv tshuab. Nws txoj haujlwm ua haujlwm yog ua raws li qhov sib nqus sib nqus thiab electromagnetic induction:
- Rotating Sib Nqus Field: Lub stator (stationary part) windings ntawm lub cev muaj zog asynchronous yog energized nrog peb -theem alternating tam sim no, tsim ib rotating magnetic teb.
- Electromagnetic Induction: Qhov no rotating teb induces tam sim no nyob rau hauv lub rotor (rotating ib feem) los ntawm electromagnetic induction.
- Torque Generation: Cov kev sib cuam tshuam ntawm cov induced tam sim no thiab rotating teb tsim torque nyob rau hauv lub rotor, ua rau nws tig.
- Slip: Lub rotor ceev ntawm lub asynchronous lub cev muaj zog yog ib txwm qis dua nws synchronous ceev (qhov ceev ntawm lub rotating teb). Qhov sib txawv ceev no hu ua plam. Lub hav zoov ntawm plam yog lub hauv paus ntawm lub cev muaj zog lub npe.
Asynchronous motors yog dav siv nyob rau hauv industrial tsav daim ntaub ntawv vim lawv cov qauv yooj yim, txhim khu kev qha kev khiav hauj lwm, thiab yooj yim ntawm txij nkawm.
