Buyini Ubudlelwano Phakathi Kombani Nokuvikelwa Kokukhuphuka?

Ukwehluleka okuhlobene nombani kuvame ukungaqondwa kahle. Ngivame ukubona izikhungo zitshala imali ekufakeni izinsimbi noma ezindongeni zombani, kuyilapho umonakalo wangaphakathi wemishini uqhubeka ukwenzeka ngemva kweziphepho.

Ukuvikelwa kokuqhuma ibhekana nemiphumela kagesi yombani, hhayi ukushaya kombani ngokwawo. Ezinhlelweni zamandla nezokulawula zanamuhla, ukuqonda ubudlelwano phakathi kombani nokuvikelwa kokukhuphuka kwegesi kubalulekile ekuvimbeleni umonakalo wemishini, isikhathi sokungasebenzi, kanye nezingozi zokuphepha.

Ukuvikelwa kombani kanye nokukhuphuka kwamandla kagesi akuzona izihloko ezihlukene. Kuyizingqimba ezixhumene zesu elilodwa lokuvikela kagesi elenzelwe ukulawula ama-overvoltage esikhashana kanye nemisinga yokukhuphuka kwamandla kagesi.

Amadivayisi Okuvikela Ukwanda Anciphisa Kanjani Ukwanda Okubangelwa Umbani?

Ukuqhuma okubangelwa umbani kulawulwa amadivayisi okuvikela ukuqhuma aguqula amandla e-overvoltage yesikhashana asuke emishinini ebucayi futhi awakhiphele phansi ngokuphephile ngaphakathi kwamasekhondi amancane.

Indlela Umbani Odala Ngayo Ukwanda Kukagesi

Umbani awudingi ukushaya indawo ngqo ukuze ubangele umonakalo. Izehlakalo zokuqhuma zivame ukwethulwa ngalezi:

• Umbani ushaya ngqo emigqeni yamandla noma yesignali

• Ukushaywa okuseduze okubangela ukukhishwa kwe-electromagnetic

• Ukwanda okungenzeka komhlabathi okuthinta izinhlelo zomhlabathi

• Imicimbi yombani ohlangothini lwezinsiza edluliselwa ngegridi

Lezi zindlela zikhiqiza ama-overvoltage esikhashana anamandla aphezulu asakazeka ngokushesha ngabaqhubi.

Indima Yamadivayisi Okuvikela Ukwanda

A idivayisi yokuvikela ukukhuphuka kohlobo 1 iklanyelwe ngqo ukuphatha imisinga yokukhanya ehlobene nombani emnyango wesevisi. Iyakwazi ukukhipha umsinga wokukhanya ongaphelele futhi inciphise amazinga aphezulu kakhulu ngaphambi kokuba angene ohlelweni lukagesi lwangaphakathi.

Imisebenzi eyinhloko yokuvikela ukukhuphuka okuhlobene nombani ihlanganisa:

• Ukubopha okusheshayo kwamandla kagesi

• Amandla okukhipha amandla kagesi aphezulu

• Ukuvikelwa kokufakwa kokushisa kwemishini okuphansi komfula

Ezindaweni eziningi zokufaka, ukuvikelwa kokuqhuma kwe-circuit breaker ihlanganiswe ukuze ihlinzeke kokubili ukuvikelwa kokusebenzisa amandla amaningi kanye nokulawulwa kokuphambuka kokukhuphuka kwamandla, ukuthuthukisa ukuhlanganiswa kohlelo kanye nokuphepha.

Kungani Ama-Breakers Ewodwa Enganele

Ama-breaker ajwayelekile asabela kancane kakhulu ezenzakalweni zesikhashana. ama-circuit breaker anezivikelo zokuqhuma Thembela ezingxenyeni zokuvikela ukukhuphuka kwangaphakathi kunezindlela zokukhubeka ezishisayo noma ezisebenza ngogesi ukuze kuncishiswe ukukhuphuka okubangelwa umbani.

Ngaphandle kwamadivayisi okuvikela ukukhuphuka azinikele, ama-transients ahlobene nombani azodlula kuma-breaker angahlolwanga.

Yiziphi Izimboni Ezidinga Ukuvikelwa Okukhethekile Kokukhuphuka Kombani?

Izimboni ezinomuzwa ophezulu wemishini, ukuchayeka ngaphandle, noma izidingo ezibalulekile zesikhathi sokusebenza zidinga ukuvikelwa okuzinikele kombani kanye nokuvikelwa kokuqhuma.

Imikhakha Yezimboni Eyingozi Kakhulu

Izimboni ezilandelayo zisengozini enkulu yezehlakalo zokuqhuma okubangelwa umbani:

• Ukukhiqizwa kukagesi kanye neziteshi ezincane

• Amandla avuselelekayo (i-PV yelanga nomoya)

• Izikhungo zokuxhumana kanye nedatha

• Ukukhiqiza kanye nokucubungula okuzenzakalelayo

• Izinhlelo zezokuthutha kanye nengqalasizinda

Lezi zindawo zivame ukuhlanganisa ukugijima kwezintambo ezinde, imishini yangaphandle, kanye nezinto zobuchwepheshe ezibucayi—izimo ezifanelekile zokusabalala kokuqhuma.

Ukuchayeka Kwesistimu ye-AC ne-DC

Umbani uthinta kokubili amanethiwekhi e-AC kanye ne-DC, kodwa indlela yokuvikela iyahluka:

• Izikhungo ezixhunywe kuzinsiza zithembele ekuhleleni okuhlelekile Ukuvikelwa kokuqhuma kwe-AC ukuphatha ama-lightning transients angena ngezinhlelo zokusabalalisa amandla.

• Ama-solar arrays, izinhlelo zebhethri, kanye nama-DC control circuits adinga ukuzinikela Ukuvikelwa kokuqhuma kwe-DC ukusingatha ukucindezeleka okuqhubekayo kwe-polarity kanye nokwanda okubangelwa umbani kuma-DC conductors.

Ukusebenzisa amadivayisi anesilinganiso se-AC ezinhlelweni ze-DC kuyiphutha elivamile nelibizayo.

Imiphumela Yokuvikelwa Okunganele

Ngaphandle kombani ofanele kanye nokuvikelwa kokuqhuma, izikhungo zibhekana nalokhu:

• Ukwehluleka kwe-elekthronikhi okuphindaphindiwe

• Ukulahleka kwedatha kanye nokungasebenzi kahle kohlelo lokulawula

• Ukunakekelwa okwandisiwe kanye nesikhathi sokuphumula

• Izingozi zokuphepha nokuthobela imithetho

Ngakho-ke ukuvikelwa kokuqhuma okuzinikele kuwukutshalwa kwezimali okuthembekile, hhayi nje into yokuvikela.

Ungaklama Kanjani Uhlelo Lokuvikela Umbani Nokukhuphuka Oluhlanganisiwe?

Ukuvikelwa kombani okuphumelelayo kanye nokwenyuka kwamandla kutholakala ngokusebenzisana phakathi kokuvikelwa kombani wangaphandle, ukumiswa komhlaba, kanye namadivayisi okuvikela ukukhuphuka kwamandla angaphakathi.

Umqondo Wokuvikela Izinga Lesistimu

Uhlelo lokuvikela oluhlelekile luvame ukufaka:

1. Ukuvikelwa kombani kwangaphandle (iziteshi zomoya, abaqhubi bezindiza) ukulawula izindlela eziqondile zokushaya

2. Amadivayisi okuvikela ukukhuphuka kohlobo 1 emnyango wenkonzo ukuze kukhishwe umbani

3. Ukuvikelwa kokuvuvukala kwesibili kumaphaneli okusabalalisa

4. Isivikelo sendawo yokusetshenziswa kwemishini ebucayi

Isendlalelo ngasinye sinciphisa amandla okukhuphuka kanye ne-voltage eseleyo kancane kancane.

Ukuxhumanisa Phakathi Kwamadivayisi

Ukuhlanganiswa okufanele kuqinisekisa ukuthi amadivayisi angenhla aphatha ukwanda kwamandla aphezulu kuyilapho amadivayisi angezansi enikeza ukulinganiselwa kwamandla kagesi amancane.

Izimiso ezibalulekile zokuxhumanisa zifaka:

• Ukukhetha okulungile kwe idivayisi yokuvikela yohlobo 1 izilinganiso

• Isikhala esanele noma ukuhlukanisa phakathi kwezigaba zokuvikela

• Ukwakheka okuqinile kokusekela kanye nokubopha

A i-breaker yokuvikela ukukhuphuka ingasetshenziswa kwezinye izakhiwo, kodwa kumele ihlanganiswe ngogesi namadivayisi okuvikela ukukhuphuka ukuze kugwenywe ukusetshenziswa kabi.

Ikhwalithi Yokumisa Nokufaka

Ngisho nomklamo wokuvikela ukukhuphuka ongcono kakhulu uyahluleka ngaphandle kokumisa kahle. Imikhuba emihle ihlanganisa:

• Izindlela zokumisa inhlabathi ezine-impedance ephansi

• Ama-lead okuxhumana amafushane, aqondile

• Ukubopha okunamandla kuzo zonke izinhlelo

Ezindaweni eziyinkimbinkimbi noma ezindaweni ezivame ukuba nombani, onjiniyela abaningi baqinisekisa umklamo wabo ngokusebenzisa ukubonisana kobuchwepheshe ukuqinisekisa ukuhambisana nezindinganiso kanye nokuthembeka kohlelo lwesikhathi eside.

Isiphetho

Ukuvikelwa kokuqhuma ungumgogodla kagesi wokuvikelwa kombani. Ngokuqonda ukwanda okubangelwa umbani, ukuhlonza izimboni ezisengozini, kanye nokuklama izinhlelo zokuvikela ezihlelekile, onjiniyela banganciphisa kakhulu umonakalo wemishini kanye nokuphazamiseka kokusebenza.

Imibuzo Evame Ukubuzwa

Kuyini ukuvikelwa kokukhuphuka kombani maqondana nombani?

Ukuvikelwa kokuqhuma kulawula ukukhuphuka kwamandla kagesi okudlulayo okubangelwa izehlakalo zombani, okuvimbela umonakalo emishinini kagesi neye-elekthronikhi.

Ingabe idivayisi yokuvikela ukukhuphuka kohlobo 1 iyadingeka ukuze kuvikelwe umbani?

Yebo. Idivayisi yokuvikela ukukhuphuka komoya yohlobo 1 yenzelwe ukukhipha imisinga yokukhuphuka ehlobene nombani emnyango wesevisi.

Ingabe ama-circuit breaker anganikeza isivikelo sokuqhuma kombani?

Ama-circuit breaker ajwayelekile awakwazi. Ama-breaker kuphela anezingxenye ezihlanganisiwe zokuvikela ukukhuphuka kwegesi anganciphisa ukukhuphuka okubangelwa umbani.

Ingabe izinhlelo ze-DC zidinga ukuvikelwa kokuqhuma kombani?

Yebo. Izinhlelo ze-DC zisengozini enkulu yokwanda okubangelwa umbani futhi zidinga amadivayisi okuvikela ukuqhuma okulinganiselwe yi-DC.

Kufanele kuhlelwe nini ukuvikela umbani kanye nokuqhuma?

Ukuvikelwa kombani kanye nokwanda komoya kufanele kuhlanganiswe ngesikhathi sokuqala kokuklama uhlelo lukagesi, hhayi ukungezwa ngemva kokwehluleka.
