1. Cov tshuab sib txawv:
DC cablesTau siv ncaj qha tam sim no kis tau tam sim no kev kho mob tom qab siv tau hauv cov tshuab hluav taws xob ua haujlwm (50Hz).
2. Qis Zog Zog Hauv Kev Sib Kis:
Nyob rau hauv kev sib piv rau ac cables, DC cleship excepit cov txheej txheem kev sib zog me me thaum lub sijhawm kis tau. Lub zog poob rau hauv DC cables yog feem ntau vim yog cov kev tiv thaiv me me, nrog kev pib poob qis (nrog rau qhov ntau ntawm tam sim no hloov pauv tom qab rectifications). Ntawm qhov tod tes, cov ac tsis kam ntawm cov khoom siv hluav taws xob tsawg dua, cov nyiaj yug me me, thiab rau cov kev tiv thaiv tawv nqaij uas tsis tshua muaj zog, thiab rau kev cuam tshuam ntawm lub siab, feem ntau yog tsim los ntawm imporance los ntawm capacitance thiab inductance.
3. Kev sib kis tau zoo thiab qis kab poob:
DC clesles muaj kev kis tau zoo thiab tsawg kawg ntawm kab poob.
4. Yooj yim rau kev hloov kho tam sim no thiab hloov pauv fais fab kev coj ua.
5. Txawm hais tias tus nqi siab dua ntawm cov khoom siv hloov dua siab tshiab piv rau cov hloov pauv, tus nqi tag nrho ntawm kev siv DC cables yog qis dua li AC Cables. DC clesles yog bipolar, thaum ac cable yog peb-xaim hluav taws xob nrog kev ua kom siab rwb thaiv tsev thiab ib qho qauv sib luag. Tus nqi ntawm AC cables yog ntau dua peb zaug uas ntawm DC cables.
6. Kev ruaj ntseg siab hauv kev siv DC cable:
- Cov yam ntxwv ntawm DC Kis tau ua rau nws nyuaj rau ntxias tau tam sim no thiab to tam sim no, zam kev cuam tshuam hluav taws xob nrog lwm tus neeg sib koom tes.
- Ib leeg-core nteg kab ke tsis tau ua kev sib nqus hysteresis los vim cov khoom siv hlau nplaum, khaws cia cov khoom siv cable steel.
- DC Cables tau muaj ntau dua cov hluav taws xob ntau dua thiab muaj peev xwm ntau dhau ntawm lub peev xwm.
- Thaum twg tib lub tshuab hluav taws xob sib txuas no tau siv rau rwb thaiv tsev rwb thaiv tsev, DC hluav taws xob yog muaj kev nyab xeeb dua li AC Electric teb.
7. Yooj yim installation, txij nkawm yooj yim, thiab tus nqi qis rau DC cables.
Kev rwb thaiv tsevYuav tsum muaj rau tib lub AC thiab DC voltage thiab tam sim no:
Thaum lub tshuab hluav taws xob ib yam rau cov rwb thaiv tsev, hluav taws xob teb hauv DC cables yog me dua li hauv AC cable. Vim yog cov qauv tseem ceeb sib txawv ntawm ob daim teb, lub siab tshaj plaws hluav taws xob lub sijhawm ua kom ze rau tus neeg saib xyuas, thaum nws paub meej hauv txheej txheem insulation. Raws li qhov tshwm sim, DC cables muaj kev nyab xeeb dua (2.4 zaug) thaum lub ntsuas tib yam tau thov rau lub rwb thaiv tsev.
