Tso lus
I. Dab tsi yog ib qho kev hloov pauv?
Ib qho kev sib tw hloov pauv yog hom transformer tshwj xeeb siv hauv cov kab sib txuas, ua kom muaj zog, kom hloov hluav taws xob siab rau cov tsheb thauj khoom uas tsav tsheb. Tsis zoo li cov fais fab txheem hluav taws xob hloov pauv, cov kev hloov pauv traction yog tsim los tiv thaiv cov kev hloov pauv hluav taws xob, ua haujlwm hnyav, ua rau lawv muaj kev lag luam hluav taws xob loj.
Cov kev hloov pauv no feem ntau yog ntsia ntawm cov hluav taws xob hluav taws xob lossis ntau yam {{}}}}}}} lub luag haujlwm hauv kev txhim kho lub zog hluav taws xob zoo thaum tswj cov ruaj khov. Lawv yuav tsum ua raws li kev lag luam nruj rau kev nyab xeeb, ua haujlwm tau zoo (EMC), tshwj xeeb tshaj yog vim tias lawv ua lag luam nyob ze rau kev kos npe thiab kev sib txuas lus.
Nrog rau kev loj hlob ntxiv ntawm kev thauj khoom ruaj khov, traction transformers yog kev tswj hwm kom txhawb nqa kev siv zog thiab cov pa roj ntsha hauv tsheb ciav hlau. Kev nce qib hauv cov ntaub ntawv (xws li high- sov superconductors yog txuas ntxiv txhawb lawv txoj kev ntseeg tau thiab kev ua tau zoo.
