Nyob hauv electrodynamometer hom wattmeter, txav coil ua haujlwm raws li lub siab kauj. Li no txav coil txuas nrog thoob plaws qhov voltage thiab yog li tam sim no ntws los ntawm cov kauj no ib txwm proportional rau qhov voltage.
Lub kauj twg yog tsau hauv wattmeter?
Ib qho electrodynamometer wattmeter muaj ob hom coils. Ib kauj yog tsau thiab lwm kauj yog txav. Lub kauj ruaj ruaj yog txuas nrog hauv series mus rau lub voj voog uas nws lub zog noj yuav tsum raug xam. Yog li no cov kauj ruaj khov no feem ntau hu ua Cov kauj tam sim no lossis yooj yim CC
Cov kauj twg siv los ua cov kauj hluav taws xob hauv Electrodynamometer wattmeter ntsuas?
Kev Tsim Kho ntawm Electrodynamometer
Cov kauj ruaj ruaj yog hu ua Current Coil thiab cov kauj txavyog hu ua Potential Chev. Cov tswj torque yog muab los ntawm ob lub spiral springs. Huab cua kev sib txhuam damping yog muab rau hauv electrodynamometer wattmeter.
Puas muaj pes tsawg coils nyob rau hauv dynamometer hom wattmeter?
Kev Tsim Kho Dynamometer Hom Wattmeter
A dynamometer hom wattmeter feem ntau muaj ob coils hu ua taag coil thiab txav coil. Lub kauj ruaj ruaj yog muab faib ua ob qhov sib npaug, uas tau muab tso rau tib lub sijhawm. Ob lub coils ruaj khov yog cua-cored kom tsis txhob muaj kev cuam tshuam hysteresis thaum siv ntawm AC.
Yuav ua li cas tswj tau siv rau Electrodynamometer?
Tawm ntawm ob, Electrodynamometer Wattmeter siv caij nplooj ntoo hlav tswj. Lub caij nplooj ntoos hlav tswj qhov system yog siv rau kev txav ntawm tus taw tes.
