Kusiyana pakati pa DC Cables ndi AC Cables

1. Njira Zosiyanasiyana Zogwiritsira Ntchito:

DC zingweamagwiritsidwa ntchito pamakina apachindunji otumizira pambuyo pokonzanso, pomwe zingwe za AC zimagwiritsidwa ntchito kwambiri pamakina amagetsi omwe amagwira ntchito pafupipafupi m'mafakitale (50Hz).

2. Kuchepa kwa Mphamvu pakutumiza:

Poyerekeza ndi zingwe za AC, zingwe za DC zimataya mphamvu pang'ono panthawi yotumizira. Kutayika kwa mphamvu mu zingwe za DC makamaka chifukwa cha kukana kwachindunji kwa ma kondakitala, ndi kutayika kwa insulation kumakhala kochepa (kutengera kukula kwa kusinthasintha kwapano pambuyo pokonzanso). Kumbali ina, kukana kwa AC kwa zingwe zotsika zamagetsi za AC ndizokulirapo pang'ono kuposa kukana kwa DC, ndipo pazingwe zothamanga kwambiri, kutayika kumakhala kofunikira chifukwa chakuyandikira komanso kuyamwa kwa khungu, komwe kutayika kwa insulation kumatenga gawo lalikulu, makamaka. opangidwa ndi impedance kuchokera ku capacitance ndi inductance.

3. Kuchita Bwino Kwambiri Kutumiza ndi Kutayika Kwapang'onopang'ono:

Zingwe za DC zimapereka mwayi wotumizira mwachangu komanso kutayika kochepa kwa mizere.

4. Yabwino kwa Kusintha Panopa ndi Kusintha Mphamvu Kufala Direction.

5. Ngakhale kuti zipangizo zosinthira zimakhala zokwera mtengo poyerekeza ndi ma transformers, mtengo wonse wogwiritsira ntchito zingwe za DC ndizochepa kwambiri kuposa zingwe za AC. Zingwe za DC zimakhala ndi bipolar, zokhala ndi dongosolo losavuta, pamene zingwe za AC zimakhala ndi magawo atatu a waya kapena mawaya asanu omwe ali ndi zofunikira zotetezera chitetezo komanso mawonekedwe ovuta kwambiri. Mtengo wa zingwe za AC ndi woposa katatu kuposa wa zingwe za DC.

6. Chitetezo Chapamwamba Pakugwiritsa Ntchito Ma Cable a DC:

- Makhalidwe amtundu wa kufalikira kwa DC kumapangitsa kuti zikhale zovuta kukopa pakali pano komanso kutayikira, kupewa kusokonezedwa ndi ma elekitiroma ndi zingwe zina zolumikizidwa.

- Zingwe zoyika pakhoma limodzi sizimatayika chifukwa cha ma tray opangidwa ndi chitsulo, zomwe zimasunga magwiridwe antchito a chingwe.

- Zingwe za DC zili ndi chitetezo chamfupi komanso chotalikirapo.

- Magawo amagetsi amagetsi omwewo akagwiritsidwa ntchito pakutchinjiriza, gawo lamagetsi la DC ndi lotetezeka kwambiri kuposa gawo lamagetsi la AC.

7. Kuyika Kosavuta, Kukonzekera Kosavuta, ndi Zotsika Zotsika za DC Cables.

 

InsulationZofunikira pa AC Yofanana ndi DC Voltage ndi Panopa:

Mphamvu yomweyi ikagwiritsidwanso ntchito pakutchinjiriza, gawo lamagetsi mu zingwe za DC ndi locheperako kuposa zingwe za AC. Chifukwa cha kusiyana kwakukulu kwapangidwe pakati pa minda iwiriyi, magetsi apamwamba kwambiri pamagetsi a AC amakhazikika pafupi ndi kondakitala, pamene mu zingwe za DC, makamaka amayang'ana mkati mwa wosanjikiza. Zotsatira zake, zingwe za DC zimakhala zotetezeka (nthawi 2.4) pomwe voteji yomweyi ikugwiritsidwa ntchito pakutsekereza.
