Rectifier locomotives, uas siv AC fais fab kis tau tus mob thiab DCmotors, tau tshwm sim, txawm tias DC commutators muaj teeb meem ob qho tib si pib thiab qis tshaj tawm. Niaj hnub no cov tshuab hluav taws xob siab heev siv brushless peb-theem AC induction motors.
Puas yog lub tshuab hluav taws xob AC lossis DC?
In a diesel– hluav taws xob locomotive, lub tshuab hluav taws xob diesel tsav yog lub tshuab hluav taws xob DC (feem ntau, tsawg dua 3,000 horsepower (2, 200 kW) net rau traction), los yog ib qho hluav taws xob AC alternator-rectifier (feem ntau 3, 000 horsepower (2, 200 kW) net lossis ntau dua rau traction), cov zis uas muab lub zog rau traction …
Puas yog lub tsheb ciav hlau AC lossis DC?
DC motors yog siv rau hauv tsheb ciav hlau yog vim lawv lub zog siab thiab tswj kom ceev ceev. Piv rau AC motors, DC motors tuaj yeem muab kev lag luam kev lag luam nrog kev sib npaug zoo ntawm lub zog pib muaj zog thiab tswj tau nrawm rau seamless tsis tau meej.
Yam twg siv tam sim no hauv tsheb ciav hlau?
Railway electrification systems siv alternating tam sim no (AC) ntawm 25 kilovolts (kV) yog siv thoob ntiaj teb, tshwj xeeb tshaj yog rau kev kub ceev.
Qhov twg zoo dua AC lossis DC?
Teb: Ac nyiam dua dc vim tias nws yooj yim los tswj thiab hloov qhov hluav taws xob ntawm ac rau kev sib kis thiab kev faib tawm. Tus nqi cog ntawm ac kis tau tus mob tsawg dua piv rau dc kis.
