Indlela i-CT esebenza kakuhle ngayo

Umgaqo Wokusebenza weTransformer yangoku

I-transformer yamandla isebenza ngokuguqula i-high primary current ibe yi-secondary current elinganayo. Umgaqo wokusebenza uxhomekeke ekungenisweni kwe-electromagnetic. Xa i-alternating current idlula kwi-primary winding, idala i-magnetic field kwi-laminated steel core. Le field ibangela i-voltage kwi-secondary winding. I-secondary current ibonisa i-primary current, kodwa kwinqanaba eliphantsi nelikhuselekileyo. Izinto zokukhusela zikhusela ii-windings kunye ne-core, ziqinisekisa ukusebenza ngokukhuselekileyo.

Umlinganiselo we-ct uchaza ubudlelwane phakathi kwe-currents yokuqala neyesibini. Umzekelo, ukuba umlinganiselo we-ct yi-100:5, ii-ampere ezili-100 kwisekethe yokuqala ziya kuvelisa ii-ampere ezi-5 kwisekethe yesibini. Olu tshintsho olulinganayo luvumela ukulinganiswa ngokuchanekileyo kunye nokukhuselwa kwiinkqubo zamandla.

Izinto ezisetyenziswa kwi-core kunye ne-windings zichaphazela ukusebenza. I-silicon steel inika i-magnetic permeability ephezulu kunye nelahleko ephantsi, nto leyo eyenza ukuba ilungele ukudluliselwa kwe-magnetic field ngokufanelekileyo. Ii-ferrite ceramics zibonelela ngobushushu obuhle kwaye zinciphisa i-eddy currents, ezifanelekileyo kwizicelo ze-high-frequency. Ii-laminated magnetic cores zinciphisa i-eddy current effects, ngelixa i-carbonyl iron ihlala izinzile kumaqondo obushushu ahlukeneyo.
