Faka isixhumi sokushaja, kodwa asikwazi ukushajwa, kufanele ngenzenjani?
Ngaphezu kwenkinga yenqwaba yokushaja noma isekethe yokunikezwa kwamandla uqobo, abanye abanikazi bezimoto abasanda kuthola imoto bangase babhekane nalesi simo lapho beshaja okokuqala. Akukho ukushaja okufunwayo. Kunezizathu ezintathu ezingaba khona zalesi simo: inqwaba yokushaja ayisekelwe kahle, i-voltage yokushaja iphansi kakhulu, kanye neswishi yomoya (i-circuit breaker) incane kakhulu ukuba ingakhubeka.
1. Ishaja ye-EV ayisekelwe kahle
Ngenxa yezizathu zokuphepha, lapho kushajwa izimoto zikagesi ezintsha zamandla, isekethe yokunikezwa kwamandla iyadingeka ukuthi ibekwe phansi kahle, ukuze uma kukhona ukuvuza ngengozi (njengokuphuka okukhulu kukagesi emotweni kagesi okubangela ukwehluleka kokufakwa kokushisa phakathi kwentambo ephilayo ye-AC nomzimba), ugesi ovuzayo ungashiywa emuva ekusakazweni kwamandla ngentambo ephansi. I-terminal ngeke ibe yingozi lapho abantu beyithinta ngengozi ngenxa yokuqongelela kweshaja kagesi evuzayo emotweni.
Ngakho-ke, kunezimfuneko ezimbili zengozi yomuntu siqu ebangelwa ukuvuza: ① Kukhona ukwehluleka okukhulu kukagesi emotweni kagesi; ② Inqwaba yokushaja ayinasivikelo sokuvuza noma isivikelo sokuvuza siyahluleka. Amathuba okuba lezi zinhlobo ezimbili zezingozi zenzeke aphansi kakhulu, futhi amathuba okuba kwenzeke ngesikhathi esisodwa ngokuyisisekelo angu-0.
Ngakolunye uhlangothi, ngenxa yezizathu ezifana nezindleko zokwakha kanye nezinga labasebenzi kanye nekhwalithi, ukwakhiwa okuningi kwamandla asekhaya kanye nengqalasizinda kagesi akukaqedwa ngokuhambisana nezidingo zokwakha. Kunezindawo eziningi lapho ugesi ungafakwanga khona kahle, futhi akunakwenzeka ukuphoqa lezi zindawo ukuthi zithuthukise ukwakheka komhlaba ngenxa yokwanda kancane kancane kwezimoto zikagesi. Ngokusekelwe kulokhu, kungenzeka ukusebenzisa izinqwaba zokushaja ezingenamhlaba ukushaja izimoto zikagesi, uma nje izinqwaba zokushaja kumele zibe nesekethe yokuvikela ukuvuza ethembekile, ukuze noma ngabe imoto entsha kagesi yamandla inokwehluleka kokufakwa kokushisa kanye nokuxhumana ngengozi, izophazamiseka ngesikhathi. Vula isekethe yokunikezwa kwamandla ukuqinisekisa ukuphepha komuntu siqu. Njengoba nje imindeni eminingi ezindaweni zasemakhaya ingenawo kahle ukwakheka komhlaba, imindeni ifakwe izivikeli zokuvuza, ezingavikela ukuphepha komuntu siqu noma ngabe kwenzeka ukushaqeka kukagesi ngengozi. Lapho inqwaba yokushaja ingashajwa, idinga ukuba nomsebenzi wokuxwayisa ongafakwanga phansi ukuze yazise umsebenzisi ukuthi ukushaja kwamanje akunawo kahle ukwakheka komhlaba, futhi kuyadingeka ukuba uqaphele futhi uthathe izinyathelo zokuphepha.
Uma kwenzeka iphutha lomhlabathi, inqwaba yokushaja isengashaja imoto kagesi. Kodwa-ke, isibonakaliso sephutha siyakhanya, futhi isikrini sokubonisa sixwayisa ngokuma okungajwayelekile komhlabathi, okukhumbuza umnikazi ukuthi aqaphele izinyathelo zokuphepha.
2. I-voltage yokushaja iphansi kakhulu
I-voltage ephansi ingenye yezizathu eziyinhloko zokungashaji kahle. Ngemva kokuqinisekisa ukuthi iphutha alibangelwa yi-underground, i-voltage iphansi kakhulu ingaba yimbangela yokwehluleka ukushaja ngokujwayelekile. I-voltage ye-AC yokushaja ingabukwa ngenqwaba yokushaja ngesibonisi noma ngokulawula okuphakathi kwemoto entsha kagesi yamandla. Uma inqwaba yokushaja ingenasikrini sokubonisa futhi i-control ephakathi yemoto entsha kagesi yamandla ingenalo ulwazi lwe-voltage ye-AC yokushaja, kudingeka i-multimeter ukuze ilinganiswe. Uma i-voltage ngesikhathi sokushaja ingaphansi kuka-200V noma ingaphansi kuka-190V, inqwaba yokushaja noma imoto ingabika iphutha futhi ayikwazi ukushajwa.
Uma kuqinisekiswa ukuthi i-voltage iphansi kakhulu, idinga ukuxazululwa ngezici ezintathu:
A. Hlola imininingwane yekhebula elithatha ugesi. Uma usebenzisa i-16A ukushaja, ikhebula kufanele okungenani libe ngu-2.5mm² noma ngaphezulu; uma usebenzisa i-32A ukushaja, ikhebula kufanele okungenani libe ngu-6mm² noma ngaphezulu.
B. I-voltage yensiza kagesi yasekhaya ngokwayo iphansi. Uma kunjalo, kubalulekile ukuhlola ukuthi ikhebula eliseceleni komuzi lingaphezu kuka-10mm², nokuthi ngabe kukhona yini izinto zikagesi ezinamandla amakhulu endlini.
C. Ngesikhathi sokusetshenziswa kukagesi okuphezulu kakhulu, isikhathi sokusetshenziswa kukagesi esiphezulu kakhulu ngokuvamile sisukela ngo-6:00 ntambama kuya ku-10:00 ntambama. Uma i-voltage iphansi kakhulu phakathi nalesi sikhathi, ingabekwa eceleni kuqala. Ngokuvamile, inqwaba yokushaja izoqala kabusha ukushaja ngokuzenzakalelayo ngemva kokuba i-voltage ibuyele esimweni sayo esijwayelekile.
Uma ingashaji, i-voltage ingu-191V kuphela, futhi i-voltage yokulahlekelwa yikhebula izoba phansi uma ishaja, ngakho-ke inqwaba yokushaja ibika iphutha le-undervoltage ngalesi sikhathi.
3. Iswishi yomoya (i-circuit breaker) ikhubekile
Ukushaja imoto kagesi kungokwamandla kagesi aphezulu. Ngaphambi kokushaja imoto kagesi, kubalulekile ukuqinisekisa ukuthi iswishi yomoya enencazelo efanele isetshenzisiwe. Ukushaja i-16A kudinga iswishi yomoya engu-20A noma ngaphezulu, kanti ukushaja i-32A kudinga iswishi yomoya engu-40A noma ngaphezulu.
Kufanele kugcizelelwe ukuthi ukushaja kwezimoto zikagesi ezintsha ezisebenzisa amandla kagesi kugesi onamandla amakhulu, futhi kuyadingeka ukuqinisekisa ukuthi yonke isekethe kanye nemishini kagesi: amamitha kagesi, izintambo, amaswishi omoya, amapulagi kanye namasokhethi nezinye izingxenye ziyahlangabezana nezidingo zokushaja. Iyiphi ingxenye engacacisiwe, iyiphi ingxenye engase ishe noma ihluleke.
