Izinqwaba zokushaja ziyizinto ezisetshenziswa kakhulu zokuphakela amandla namuhla, kodwa kusenabantu abaningi abangazi ukuthi mangaki ama-square metres ezintambo ezidingekayo ukuze kufakwe izinqwaba zokushaja.Ubukhulu bezintambo zokubopha inqwaba yokushaja abukwazi ukuxoxwa ngokufanayo.Inqunywa ngokuyinhloko umthamo wokugcina amandla wenqwaba yokushaja kanye ne-voltage ihhanisi lezintambo ezimelana nalo lapho amandla ehamba.Ngokuvamile, izintambo zenqwaba yokushaja ziningi kakhulu kunezinye izintambo, namuhla ake sifunde indlela yokukhetha ikhebula elifanele lapho ufaka inqwaba yokushaja.
1.Ukukhetha ikhebula
Izinqwaba zokushaja zihlukaniswe ngesigaba esisodwa nesigaba sesithathu.Ngaphandle kwezigaba ezimbili noma isigaba esisodwa, isinyathelo sokuqala ukuguqulela ku-AC engenayo yamanje.
(1) Okwezinqwaba zokushaja zesigaba esisodwa (izinqwaba zokushaja i-AC) I=P/U
(2) Ngenqwaba yokushaja yezigaba ezintathu (inqwaba yokushaja ye-DC) I=P/(U*1.732) Ngemva kokubala i-current ngale ndlela, khetha ikhebula ngokuvumelana nomthamo wamanje.
Ukukhetha ikhebula kungabhekisa kumamanuwali afanelekile noma izinqubo ezifana nalezi:
(1) Inqwaba yokushaja yesigaba esisodwa ngokuvamile i-7KW (inqwaba yokushaja ye-AC).Ngokusho kwe-I=P/U=7000/220=32A, kufanele kusetshenziswe intambo yethusi ewumgogodla wamamilimitha-skwele angu-4.
(2) Inqwaba yokushaja yezigaba ezintathu (inqwaba ye-DC) 15KW yamanje 23A ikhebula 4 amamilimitha-skwele 30KW yamanje 46A ikhebula 10 square millimeters 60KW yamanje 92A ikhebula 25 square millimeters 90KW yamanje 120A intambo 35 square millimeters Ngaphezu kwalokho, zonke inqwaba yokushaja kufanele ibe nenqwaba yokushaja ucingo kanye nocingo oluphansi.Ngakho-ke, ikhebula lesigaba esisodwa sesithathu liyadingeka, futhi ikhebula lezigaba ezintathu eziyinhloko liyadingeka.
2.Izidingo zokwakha
Njengoba inqwaba yokushaja imoto kagesi (ibhawodi) ohlangothini lokusabalalisa amandla egridi yamandla, ukwakheka kwayo kunquma ukuthi izici zesistimu yokuxhumana okuzenzakalelayo ziningi futhi amaphuzu ahlakazekile alinganisiwe, ukuhlanganisa okubanzi, nebanga elifushane lokuxhumana.Futhi ngokuthuthuka kwedolobha, i-topology yenethiwekhi idinga ukwakheka okuguquguqukayo nokunokwehla.Ngakho-ke, ukukhethwa kwemodi yokuxhumana yenqwaba yokushaja imoto kagesi (ibhawodi) kufanele kubhekwe lezi zindaba ezilandelayo:
❶Ukwethembeka kokuxhumana -Uhlelo lokuxhumana kumele lumelane novivinyo lwendawo enokhahlo kanye nokuphazamiseka okunamandla kazibuthe kagesi noma ukuphazamiseka komsindo isikhathi eside, futhi lugcine ukuxhumana kushelela.
❷Izindleko zokwakha -ngesisekelo sokwanelisa ukwethembeka, cabangela ngokuphelele izindleko zokwakha kanye nezindleko zokusebenzisa nokunakekela isikhathi eside.
❸Ukuxhumana okubili -hhayi kuphela ukulayishwa kolwazi, kodwa nokukhululwa kokulawula.
❹Izinga lokudluliswa kwedatha yezinsiza eziningi -Ngokukhula okuqhubekayo kwethrafikhi yetheminali esikhathini esizayo, ukuxhumana phakathi kwesiteshi esikhulu nesiteshi esincane, kanye nesiteshi esincane kuya esikhumulweni sezindiza kudinga amanani aphezulu naphezulu okudlulisa idatha ezinsizeni eziningi.
❺Ukuvumelana nezimo nokuqina kokuxhumana -Ngenxa yokuthi izinqwaba zokushaja (amabhawodi) zinezici zezindawo eziningi zokulawula, izindawo ezibanzi, nokusabalalisa, izinqubo zokuxhumana ezijwayelekile ziyadingeka.Ngokuthuthukiswa kwemikhuba namandla enethiwekhi yenethiwekhi “Yonke i-IP” Ngokukhula okuqhubekayo kwebhizinisi lokusebenza, kuyadingeka ukucabangela umphathi wesevisi osekwe ku-IP, futhi ngasikhathi sinye, kuyadingeka ukwenza lula ukufakwa, ukugunyazwa, ukusebenza, kanye ukunakekela.
