Qhov txawv ntawm ib hom qhuav Transformer

Lub tshuab ziab khaub ncaws qhuav muaj ntau yam sib koom ua ke uas ua kom muaj zog hloov pauv. Paub txog cov khoom no thiab lawv lub luag haujlwm tuaj yeem pab koj nkag siab tias lub tshuab hloov pauv ua haujlwm li cas. Ntawm no yog ib daim ntawv teev cov qhuav hom transformer qhov chaw:

 

Core thiab Windings

Thawj winding, txuas nrog lub hwj chim qhov chaw, ua alternating tam sim no nyob rau hauv ib ncig txoj kev nyob ib ncig ntawm lub core los tsim ib tug magnetic teb. Daim teb no induces ib tug voltage nyob rau hauv lub thib ob winding, enabling zog hloov ntawm thawj thiab theem nrab voltages. Tus naj npawb ntawm cov lem nyob rau hauv txhua qhov winding txiav txim siab qhov transformer qhov voltage transformation ratio. Cov khaubncaws sab nraud povtseg ntxiv rau cov windings tuaj yeem txhim kho kev ua haujlwm.

• Core:Cov ntawv laminated ntawm hwm silicon steel txo qis eddy tam sim no poob thiab sib nqus hysteresis, pab txhawb zog efficiency.
• Primary winding:Txuas nrog lub hwj chim qhov chaw, nws generates ib magnetic teb uas pib lub zog hloov.
• Secondary winding:Induces voltage los ntawm electromagnetic induction ntawm cov tub ntxhais, xa lub zog mus rau lub load.
