Lub transformer poob ntau npaum li cas?

Cov tooj liab poob hauv transformer feem ntau yog 0.5 feem pua, thiab cov hlau poob feem ntau yog 5-7 feem pua ​​. Lub transformer poob yog hais txog cov sum ntawm qhov tsis muaj-load poob Po, luv luv-circuit poob Pk thiab stray poob Ps. Lub transformer siv lub hauv paus ntsiab lus ntawm electromagnetic induction rau A ntaus ntawv rau kev hloov AC voltage. Copper poob yog lub zog siv los ntawm kev ua haujlwm ntawm cov thawj thiab theem nrab windings thaum tam sim no dhau los ntawm thawj thiab theem nrab windings ntawm lub transformer. Kev poob tooj liab kuj hu ua kev poob qis. Ntev npaum li qhov tam sim no ntawm thawj thiab theem nrab windings yog khaws cia tsis hloov, qhov ntsuas tooj liab poob yog qhov poob tas li. Lub tooj liab poob meter yog siv los ntsuas qhov poob ntawm tooj liab kauj ntawm lub transformer, uas hloov nrog lub load tam sim no, thiab tooj liab poob zog yog proportional rau square ntawm lub load tam sim no.
