Ukuqinisekisa ukuphepha okuphezulu kwabaphuluki bemisilinga ye-DC

Emkhakheni wezinhlelo zikagesi, ukuphepha kuhlala kuyinto ebaluleke kakhulu. Njengoba isidingo samandla avuselelekayo siyaqhubeka nokukhula, ukusetshenziswa kwe-Direct yamanje (DC) kuya ngokuya kuvame kakhulu. Kodwa-ke, lolu shintsho ludinga onogada abakhethekile ukuqinisekisa ukuphepha kwabasebenzi nemishini. Kulesi sifundo sebhulogi, sizohlola izingxenye ezibalulekile zeI-DC Circuit Breakernokuthi basebenzisana kanjani ukuhlinzeka ngokuvikelwa okuthembekile.

1. Idivayisi yokuvikelwa yokuvuza ye-AC
Uhlangothi lwe-AC lwe-DC Breaker lufakwe idivaysi yamanje (RCD) ye-Resident yamanje (RCD), eyaziwa nangokuthi i-Resiual Preciker Breaker (RCCB). Le divayisi iqapha ukuhamba kwamanje phakathi kwezintambo eziphilayo nezingathathi hlangothi, ukuthola noma yikuphi ukungalingani okubangelwa yiphutha. Lapho kutholwa lokhu kungalingani, i-RCD ngokushesha iphazamisa umjikelezo, ivikele ubungozi bokushaqeka kukagesi kanye nokunciphisa ukulimala okungaba khona kohlelo.

2. Iphutha le-DC esibulalayo lidlula emshweni:
Phendukela ohlangothini lwe-DC, sebenzisa umtshina wesiteshi esinephutha (idivaysi yokuhlola ukufaka). Umtshina udlala indima ebalulekile ekubhekeni okuqhubekayo kohlelo lokuvikelwa kohlelo lukagesi. Uma kwenzeka iphutha kanye namaconsi okumelana kokufakelwa ngaphansi komkhawulo onqunyelwe kusengaphambili, umtshina wesiteshi esinephutha uhlonza iphutha futhi uqala isenzo esifanele ukusula iphutha. Izikhathi zokuphendula okusheshayo ziqinisekisa amaphutha awakhuphuki, ukuvimba izingozi ezingaba khona kanye nomonakalo wemishini.

I-3
Ngokungeziwe kumshini wesiteshi se-Fault Channel, uhlangothi lwe-DC lwe-DC Breaker luhlome nge-Ground Protection Parteit Breaker. Le ngxenye iyasiza ukuvikela uhlelo emaphutheni ahlobene nomhlabathi, njengokuqhekeka kokufakwa esikhundleni noma ukuncipha kombani. Lapho kutholwa iphutha, i-Ground Protectuit Breaker Breaker ivula ngokuzenzakalelayo umjikelezo, onqamula ngempumelelo isigaba esinephutha kusuka ohlelweni futhi avimbele okunye ukulimala.

Ukuxazulula inkinga okusheshayo:
Ngenkathi ama-DC Circuit Breakers ahlinzeka ngokuvikelwa okuqinile, kufanelekile ukuthi kuqaphele ukuthi isenzo esisheshayo esizeni sibalulekile ukuze uxazulule inkinga ngesikhathi. Ukubambezeleka ekuxazululeni amaphutha kungahlehlisa ukusebenza kwamadivayisi wokuvikela. Ngakho-ke, ukulungiswa okujwayelekile, ukuhlola, nokuphendula okusheshayo kunoma iyiphi inkomba yokwehluleka kubalulekile ukuze kuqinisekiswe ukuqhubeka kokwethenjwa kohlelo.

Ukuvikelwa kwemikhawulo yamaphutha aphindwe kabili:
Kubalulekile ukuqonda ukuthi ngisho nalezi zingxenye ezivikelayo ezekhona, i-DC Breaker Creaker kungenzeka ingaqiniseki ukuvikeleka uma kwenzeka iphutha eliphindwe kabili. Amaphutha aphindwe kabili avela lapho amaphutha amaningi avela ngasikhathi sinye noma ngokulandelana okusheshayo. Ubulukhuni bokuhlanza ngokushesha amaphutha amaningi babeka izinselelo ekuphenduleni ngempumelelo kwezinhlelo zokuvikela. Ngakho-ke, ukuqinisekisa ukuklanywa kohlelo olufanele, ukuhlolwa okujwayelekile, kanye nezinyathelo zokuvimbela kuyadingeka ukunciphisa ukwehluleka okuphindwe kabili.

Ngokufigqiwe:
Njengobuchwepheshe bamandla obuvuselelekayo bayaqhubeka nokuvela, ukubaluleka kwezindlela ezifanele zokuvikelwa okufana nokuqhekeka kwesifunda kwe-DC akunakugcizelelwa. Inhlanganisela yedivaysi yamanje ye-AC eseceleni, umtshina wesiteshi se-DC Side Fault kanye ne-Ground Protect Circuit Breaker isiza ukuthuthukisa ukuphepha okuphelele nokwethenjwa kohlelo lukagesi. Ngokuqonda umsebenzi walezi zinto ezibucayi futhi sixazulule ukwehluleka ngokushesha, singakha indawo ephephile kagesi yawo wonke umuntu othintekayo.
