Ophwanya Madera Akufotokozedwa: Chitetezo, Gulu, ndi Kugwiritsa Ntchito
Kodi Circuit Breaker ndi chiyani?
Ma circuit breaker ndi zida zazikulu zodzitetezera zomwe zimagwiritsidwa ntchito podula mabwalo olakwika pamakina amagetsi. Ntchito zawo zazikuluzikulu zikuphatikiza chitetezo chochulukirachulukira, chitetezo chachifupi, komanso kudzipatula kwamagetsi.
Zowononga kuzungulira amagawidwa ndi kugwiritsa ntchito Miniature (MCB), Molded Case (MCCB), Air (ACB), Vacuum (VCB), ndi Residual Current (RCCB/RCBO) mitundu.
Iwo amagwira ntchito kudzera kutentha (kuchuluka) ndi maginito (yozungulira) njira zochepetsera thupi kulumikizidwa mwachangu.
Mu machitidwe owongolera magalimoto, zophwanya ntchito ngati zosintha zazikulu zachitetezo, kugwira ntchito limodzi zolumikizira (zakutali) ndi ma relay otenthetsera (kuti atetezeke mochulukira).
Kusankha ayenera kuganizira oveteredwa panopa, kuswa mphamvu, pole count,ndi kuzungulira (mwachitsanzo, mtundu C wa chitetezo chokhazikika pamagalimoto) kukumana katundu ndi dongosolo amafunikira molondola.
