Ukuqonda Ukubaluleka kwee-RCBOs kuKhuseleko lweSekethe

Kwihlabathi lokhuseleko lwesekethe, igama elithi MCB limele i-miniature breaker circuit. Esi sixhobo se-electromechanical sidlala indima ebalulekileyo ekuvaleni ngokuzenzekelayo isiphaluka xa kufunyenwe iimeko ezingaqhelekanga. I-Overcurrent ebangelwa yi-short circuit ibonakala lula yi-MCB. Umgaqo wokusebenza we-miniature breakers circuit ilula kwaye iyasebenza. Ibandakanya abafowunelwa ababini; enye ilungisiwe kwaye enye iyasuswa. Xa ukwanda kwangoku, abafowunelwa abahambahambayo baqhawula kubafowunelwa abasisigxina, bavule isiphaluka kwaye baqhawule kumbane oyintloko. Nangona kunjalo, kwiinkqubo zombane zanamhlanje eziphambili, indima yeI-RCBO(i-residual current circuit breaker kunye ne-overcurrent protection) ekunikezeni ukhuseleko olubanzi lweesekethe luba lubaluleke kakhulu.

Ii-RCBOszizinto ezibalulekileyo kwiinkqubo zombane zanamhlanje, ezibonelela ngokudityaniswa kokhuseleko lwangoku olushiyekileyo kunye nokukhuselwa ngokugqithisileyo kwisixhobo esinye. Zenzelwe ukukhusela iisekethe kwi-overcurrent, eyona nto iphosakeleyo yombane ebangelwa ukugqithiswa okanye isiphaluka esifutshane. Ukhuseleko lwangoku olushiyekileyo oludityanisiweyo kwi-RCBO longeza umaleko owongezelelweyo wokhuseleko ngokufumanisa kunye nokwaphula isiphaluka xa ukuvuza kwangoku kusenzeka, oku kunokubangela ukothuka okanye ingozi yomlilo. Oku kusebenza okuphezulu kwenza i-RCBO ibe yinto ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kofakelo lombane.

Enye yeenzuzo eziphambili zeIi-RCBOs kukukwazi ukubonelela ngokhuseleko lomntu kwisekethe nganye. Ngokungafaniyo nee-MCB zemveli ezibonelela ngokhuseleko olugqithileyo kwisekethe yonke, ii-RCBOs zodwa kwaye zikhusela iisekethe ezizimeleyo ngaphakathi kwebhodi yokuhambisa. Eli nqanaba le-granularity yokukhusela iluncedo ngokukodwa kwiindawo zokuhlala, zorhwebo, kunye nezoshishino apho iisekethe ezahlukeneyo zinokuba namanqanaba ahlukeneyo ovakalelo kunye neemfuno zomthwalo. Ngokudibanisa ii-RCBOs kwiziseko zombane, umngcipheko wokucima umbane okuxhaphakileyo ngenxa yokusilela kwendawo kuncitshiswe kakhulu, ngaloo ndlela kuphuculwa ukomelela ngokubanzi kwenkqubo yamandla.

Uyilo oludityanisiweyo lwee-RCBOs luzenza zilungele ukufakelwa kombane kwale mihla apho ukwenziwa kwendawo kuyinto ephambili. Badibanisa ukukhuselwa kwangoku okushiyekileyo kunye nokukhuselwa ngokugqithisileyo kwisixhobo esisodwa, ukwenza lula isicwangciso sokukhusela isiphaluka jikelele, ukunciphisa imfuno yamacandelo amaninzi kunye nokwenza lula inkqubo yokufakela. Oku akuncedi nje kuphela ukugcina iindleko, kukwaqinisekisa ukwakheka kwepaneli yombane esebenzayo kunye nelungelelanisiweyo.

Ukuhlanganiswa kwee-RCBOs kukhuseleko lwesekethe kubonisa ukuqhubela phambili okubonakalayo ekuqinisekiseni ukhuseleko nokuthembeka kofakelo lombane. Ngokudibanisa ukukhuselwa kwangoku okushiyekileyo kunye nokukhuselwa ngokugqithisileyo kwisixhobo esinye, ii-RCBO zibonelela ngokhuseleko olubanzi lweesekethe zomntu ngamnye, ngaloo ndlela ziphucula ukomelela ngokubanzi kwenkqubo yombane. Uyilo lwayo oludibeneyo kunye nokusebenza okulula kwenza ukuba kube yinto efanelekileyo yofakelo lombane lwangoku, ukubonelela ngesisombululo esisebenzayo sokukhusela isekethe ngokufanelekileyo. Njengoko imfuno yokhuseleko lombane olwandisiweyo iqhubeka ikhula, indima ye-RCBOs ekukhuseleni iisekethe iya kuba yinto ebaluleke kakhulu kwishishini.
