1. Kev siv ntau yam:
DC cablesyog siv nyob rau hauv ncaj qha kis tau tus mob systems tom qab rectification, thaum AC cables feem ntau siv nyob rau hauv lub hwj chim systems khiav hauj lwm ntawm lub industrial zaus (50Hz).
2. Tsawg zog poob hauv kev sib kis:
Nyob rau hauv kev sib piv rau AC cables, DC cables qhia me me zog poob thaum lub sij hawm kis tau tus mob. Lub zog poob hauv DC cables feem ntau yog vim qhov ncaj qha tam sim no tsis kam ntawm cov neeg siv hluav taws xob, nrog cov rwb thaiv tsev poob qis me me (nyob ntawm qhov loj ntawm qhov hloov pauv tam sim no tom qab kho). Ntawm qhov tod tes, AC tsis kam ntawm qis-voltage AC cables yog me ntsis loj dua li DC tsis kam, thiab rau high-voltage cables, poob yog qhov tseem ceeb vim qhov sib thooj ntawm cov nyhuv thiab cov nyhuv ntawm daim tawv nqaij, qhov twg rwb thaiv tsev losses ua lub luag haujlwm tseem ceeb, feem ntau. tsim los ntawm impedance los ntawm capacitance thiab inductance.
3. High Transmission Efficiency thiab Low Line Poob:
DC cables muaj kev sib kis tau zoo thiab tsawg kawg kab poob.
4. Yooj yim rau kev hloov kho tam sim no thiab hloov kev xa hluav taws xob kev taw qhia.
5. Txawm hais tias tus nqi siab dua ntawm cov khoom siv hloov pauv piv rau cov hloov pauv, tag nrho cov nqi ntawm kev siv DC cables yog qis dua li ntawm AC cables. DC cables yog bipolar, nrog ib tug yooj yim qauv, thaum AC cables yog peb-theem plaub-xaim los yog tsib-xaim tshuab nrog siab rwb thaiv tsev kev ruaj ntseg thiab ib tug complex qauv. Tus nqi ntawm AC cables yog ntau tshaj peb npaug ntawm DC cables.
6. Kev nyab xeeb siab hauv kev siv DC Cables:
- Cov yam ntxwv ntawm DC kis tau tus mob ua rau nws nyuaj rau induce tam sim no thiab to tam sim no, tsis txhob electromagnetic cuam tshuam nrog lwm cov co-pw cables.
- Ib leeg-tub ntxhais nteg cables tsis muaj kev sib nqus hysteresis poob vim steel structural cable tais, khaws cia cable kis tau tus mob.
- DC cables muaj peev xwm tiv thaiv luv luv thiab overcurrent.
- Thaum tib qhov hluav taws xob hluav taws xob siv rau kev rwb thaiv tsev, DC hluav taws xob hluav taws xob muaj kev nyab xeeb dua li AC hluav taws xob.
7. Kev txhim kho yooj yim, kev tu yooj yim, thiab tus nqi qis dua rau DC Cables.
Rwb thaiv tsevKev xav tau rau tib yam AC thiab DC Voltage thiab tam sim no:
Thaum tib qhov hluav taws xob raug siv rau kev rwb thaiv tsev, hluav taws xob hauv DC cables tsawg dua li hauv AC cables. Vim yog qhov sib txawv ntawm cov qauv sib txawv ntawm ob lub teb, qhov siab tshaj plaws hluav taws xob thaum lub sij hawm AC cable energization yog concentrated nyob ze ntawm tus neeg xyuas pib, thaum nyob rau hauv DC cables, nws mas concentrates nyob rau hauv lub rwb thaiv tsev txheej. Yog li ntawd, DC cables muaj kev nyab xeeb dua (2.4 npaug) thaum tib qhov hluav taws xob raug siv rau cov rwb thaiv tsev.
