1. Different Utilization Systems:
DC cablesanoshandiswa mune yakananga ikozvino masystem ekutepfenyura mushure mekugadzirisa, nepo AC tambo dzinowanzo shandiswa mumasisitimu emagetsi anoshanda pamaindasitiri frequency (50Hz).
2. Kuderera Kwesimba Mukutapurirana:
Mukuenzanisa netambo dzeAC, tambo dzeDC dzinoratidza kurasikirwa kwesimba kudiki panguva yekufambisa. Kurasika kwesimba mumatambo eDC kunonyanya kukonzerwa nekupokana kwazvino kwemakondakita, nekurasikirwa kwekudzivirira kuri kudiki (zvinoenderana nehukuru hwekuchinja kwazvino mushure mekugadzirisa). Kune rimwe divi, iyo AC inopokana yeakadzika-voltage AC tambo yakakura zvishoma pane iyo DC kuramba, uye kune akakwira-voltage tambo, kurasikirwa kwakakosha nekuda kwekuswedera kwekuita uye ganda, uko kurasikirwa kwekudzivirira kunobata basa rakakura, kunyanya. inogadzirwa ne impedance kubva kune capacitance uye inductance.
3. High Transmission Efficiency uye Low Line Kurasika:
DC tambo dzinopa yakakwirira kutapurirana kunyatsoshanda uye kushoma mutsara kurasikirwa.
4. Yakanakira Kugadzirisa Iyezvino uye Kuchinja Mafambisirwo eMagetsi.
5. Pasinei nemutengo wepamusoro wezvigadzirwa zvekushandura zvichienzaniswa nemagetsi, mari yose yekushandisa DC cables yakaderera zvikuru kupfuura iyo ye AC cables. DC tambo dzine bipolar, ine chimiro chakareruka, nepo AC tambo dziri nhatu-phase mana-waya kana shanu-waya masisitimu ane yakakwirira insulation kuchengetedza zvinodiwa uye chimiro chakaoma. Mutengo wetambo dzeAC wakapetwa katatu kupfuura wetambo dzeDC.
6. Kuchengetedzwa Kwepamusoro Mukushandiswa kweDC Cables:
-Mamiriro ehunhu ekutapurirana kweDC anoita kuti zviome kupinza zvazvino uye kudonha kwazvino, kudzivirira kukanganiswa kwemagetsi nemamwe tambo dzakabatanidzwa.
-Single-core akaiswa tambo haawane magineti hysteresis kurasikirwa nekuda kwesimbi dhizaini tambo matireyi, kuchengetedza tambo yekufambisa kuita.
- DC tambo dzine yakakwirira pfupi-yedunhu uye overcurrent kudzivirira masimba.
- Kana iwowo magetsi emagetsi minda akaiswa kune insulation, DC yemagetsi munda yakachengeteka zvakanyanya kupfuura AC yemagetsi munda.
7. Kuiswa Kwakareruka, Kugadziriswa Kuri Nyore, uye Mari Dzakaderera dzeDC Cables.
InsulationZvinodikanwa zveSame AC uye DC Voltage uye Zvazvino:
Kana iyo vhezheni imwe chete ichiiswa kune yekuvharira, iyo yemagetsi munda muDC tambo idiki zvakanyanya pane AC tambo. Nekuda kwekusiyana kwakakosha kwemaitiro pakati peminda miviri iyi, iyo yakakura yemagetsi munda panguva yeAC tambo yesimba inonamirwa padyo nekondukita, nepo muDC tambo, inonyanya kutarisisa mukati meiyo insulation layer. Nekuda kweizvozvo, tambo dzeDC dzakachengetedzeka (2.4 nguva) kana iwo magetsi akafanana akaiswa kune insulation.
