DC cable muaj cov yam ntxwv hauv qab no piv nrog AC cable.
1. Cov txheej txheem siv yog txawv. DC cable yog siv nyob rau hauv lub rectified DC kis tau tus mob, thiab AC cable feem ntau yog siv nyob rau hauv lub hwj chim zaus (hauv tsev 50 Hz) fais fab system.
2. Piv nrog rau AC cable, lub zog poob thaum lub sij hawm kis ntawm DC cable yog me me.
Lub zog poob ntawm DC cable feem ntau yog DC tsis kam ntawm tus neeg xyuas pib, thiab cov rwb thaiv tsev poob yog me me (qhov loj nyob ntawm qhov hloov pauv tam sim no tom qab kho).
Thaum AC tsis kam ntawm cov hluav taws xob qis AC cable yog me ntsis loj dua li DC tsis kam, lub high-voltage cable yog pom tseeb, feem ntau yog vim muaj kev sib thooj thiab cov nyhuv ntawm daim tawv nqaij, qhov poob ntawm rwb thaiv tsev tsis kam nyiaj rau ib qho loj, feem ntau yog impedance generated los ntawm lub capacitor thiab inductor.
3. Kev sib kis tau zoo thiab tsis tshua muaj kab poob.
4. Nws yog qhov yooj yim los kho qhov tam sim no thiab hloov lub zog xa hluav taws xob.
5. Txawm hais tias tus nqi ntawm cov khoom siv converter yog siab dua li ntawm lub transformer, tus nqi ntawm kev siv cov kab hluav taws xob yog qis dua li ntawm AC cable.
DC cable yog qhov zoo thiab tsis zoo ncej, thiab cov qauv yooj yim; AC cable yog peb-theem plaub-xaim, los yog tsib-xaim system, qhov kev ruaj ntseg ntawm rwb thaiv tsev yuav tsum siab, cov qauv yog complex, thiab tus nqi cable yog ntau tshaj peb npaug ntawm DC cable.
6. DC cable muaj kev nyab xeeb siv:
1) Cov yam ntxwv ntawm DC kis tau tus mob, nws yog ib qho nyuaj rau tsim induced tam sim no thiab to tam sim no, thiab nws yuav tsis cuam tshuam nrog hluav taws xob teb generated los ntawm lwm yam cables.
2) Ib leeg-ntxhais nteg cable tsis cuam tshuam rau kev sib kis ntawm cable vim qhov hysteresis poob ntawm steel qauv choj.
3) Nws muaj peev xwm cuam tshuam ntau dua thiab kev tiv thaiv hla dhau DC cables ntawm tib lub qauv.
4) Ib qho ncaj, hloov hluav taws xob ntawm tib qhov hluav taws xob yog siv rau cov rwb thaiv tsev, thiab DC hluav taws xob hluav taws xob muaj kev nyab xeeb dua li AC hluav taws xob.
7. Kev teeb tsa thiab kev saib xyuas ntawm DC cable yog qhov yooj yim thiab tus nqi qis.
