Milu yolipiritsa ndi zida zodziwika bwino zoperekera mphamvu masiku ano, komabe pali anthu ambiri omwe sakudziwa kuti mawaya angati amafunikira kuti akhazikitse milu yolipiritsa.Makulidwe a ma wiring harness a mulu wolipiritsa sangathe kukambidwa mofanana.Zimatsimikiziridwa makamaka ndi mphamvu yosungiramo mphamvu ya mulu wolipiritsa ndi voteji yomwe wiring harness imapirira pamene mphamvu ikuyenda.Nthawi zambiri, mawaya a mulu wothamangitsa amakhala okhuthala kwambiri kuposa mawaya ena, lero tiphunzire momwe tingasankhire chingwe choyenera pakuyika mulu wothamangitsa.
1.Kusankha chingwe
Milu yolipira imagawidwa mu gawo limodzi ndi magawo atatu.Mosasamala za magawo awiri kapena gawo limodzi, gawo loyamba ndikusinthira ku AC yomwe ikubwera.
(1) Pamilu yolipiritsa yagawo limodzi (milu yochapira AC) I=P/U
(2) Kwa mulu wothamanga wa magawo atatu (DC yojambulira mulu) I = P / (U * 1.732) Pambuyo powerengera zamakono motere, sankhani chingwe molingana ndi panopa.
Kusankha chingwe kungatanthauze zolemba kapena njira zoyenera monga:
(1) Mulu wothamangitsa wagawo limodzi nthawi zambiri umakhala 7KW (mulu wothamangitsa wa AC).Malinga ndi I=P/U=7000/220=32A, chingwe chapakati chamkuwa cha 4 square millimeters chiyenera kugwiritsidwa ntchito.
(2) Mulu wothamangitsa magawo atatu (mulu wa DC) 15KW pano 23A chingwe 4 lalikulu mamilimita 30KW panopa 46A chingwe 10 lalikulu mamilimita 60KW panopa 92A chingwe 25 masikweya millimeters waya ndi waya pansi.Choncho, chingwe chimodzi chamagulu atatu chimafunika, ndipo chingwe chachisanu chachisanu chimafunika.
2.Zofunikira zomanga
Monga mulu wothamangitsa galimoto yamagetsi (bawuti) kumbali yogawa mphamvu ya gridi yamagetsi, kapangidwe kake kamatsimikizira kuti mawonekedwe a njira yolumikizirana yodziwikiratu ndi ambiri komanso amwazikana mfundo zoyezera, kufalikira kwakukulu, ndi mtunda waufupi wolumikizana.Ndipo ndi chitukuko cha mzindawu, ma topology a netiweki amafunikira mawonekedwe osinthika komanso owopsa.Chifukwa chake, kusankha njira yolumikizirana ya mulu wothamangitsa galimoto yamagetsi (bawuti) kuyenera kuganizira izi:
❶Kudalirika kwa kulumikizana -Njira yolumikizirana iyenera kupirira kuyesedwa kwa chilengedwe komanso kusokoneza kwamphamvu kwa ma elekitiroma kapena kusokoneza kwa phokoso kwa nthawi yayitali, ndikusunga kulumikizana bwino.
❷Mtengo womanga -pazifukwa zokhutiritsa kudalirika, ganizirani mozama mtengo wa zomangamanga ndi mtengo wa ntchito ndi kukonza kwa nthawi yayitali.
❸Kulumikizana kwanjira ziwiri -osati kukweza kwa chidziwitso, komanso kumasulidwa kwa ulamuliro.
❹Mlingo wotumizira ma data osiyanasiyana -Ndi kukula kosalekeza kwa magalimoto oyendetsa magalimoto m'tsogolomu, kuyankhulana pakati pa siteshoni yaikulu ndi siteshoni yaing'ono, ndi sub-station kupita ku terminal kumafuna mitengo yapamwamba komanso yapamwamba yotumizira deta kwa mautumiki ambiri.
❺Kusinthasintha ndi scalability kulankhulana -Chifukwa milu yolipiritsa (maboliti) ali ndi mawonekedwe a malo ambiri owongolera, madera ambiri, ndi kubalalitsidwa, njira zolumikizirana zokhazikika zimafunikira.Ndi chitukuko cha "ALL IP" zamakono zamakono zamakono ndi mphamvu Ndi kukula kosalekeza kwa bizinesi yogwira ntchito, m'pofunika kuganizira za IP-based service bearer, ndipo panthawi imodzimodziyo, imayenera kuthandizira kukhazikitsa, kutumiza, kugwira ntchito, ndi ntchito. kukonza.
