Ukuntywila nzulu kwiResidual Current Operated Circuit Breaker (RCBO)

Kwiinkqubo zombane zanamhlanje ezisebenzisa umbane ophantsi, ukhuseleko kunye nokuthembeka zibaluleke kakhulu.I-Residual Current Operated Circuit Breaker eSebenzayo (I-RCBO) sisixhobo esibalulekileyo sokukhusela esenzelwe ukuthintela iingozi zombane ezifana nokutshayiswa kombane kunye nemililo ebangelwa ziimpazamo zombane. Ngokudibanisa ukhuseleko olugqithisileyo, i-short-circuit, kunye nokhuseleko lwamandla asele, i-RCBO inika ukhuseleko olupheleleyo kwizicelo ezahlukeneyo. Kule posi, siza kuhlola iimpawu eziphambili kunye neenkcukacha zobugcisa ze-RCBO kunye nendima yazo ekukhuseleni iinkqubo zombane.

Umsebenzi oPhambili we-RCBO

I-RCBO idibanisa iindlela ezininzi zokukhusela kwisixhobo esinye. Umsebenzi wayo ophambili kukubona ukugqithiswa kakhulu, ii-short circuits, okanye ii-residual currents (ii-leakage currents) kwaye ikhuphe umbane ngoko nangoko ukuthintela ingozi enokubakho ebantwini nakwipropathi. Oku kwenza ii-RCBO zibe nokuguquguquka okukhulu, njengoko zisebenza kwiindawo ezahlukeneyo, ukusuka kwiindawo zokuhlala ukuya kwiindawo zorhwebo nezoshishino.

Iinkcukacha zoBugcisa eziphambili kunye neempawu

1. Uluhlu lwangoku olulinganisiweyo: Ii-RCBO ziza ngeendlela ezahlukeneyo zangoku ezilinganisiweyo ukuze zilungele usetyenziso olwahlukeneyo. Iimodeli eziqhelekileyo ezifana ne-CMTB1LE-32 kunye ne-CMTB1LE-63 zigubungela uluhlu lwangoku ukusuka kwi-3A ukuya kwi-63A. Ngokukodwa, i-CMTB1LE-32 ifumaneka kuluhlu lwe-3A, 6A, 10A, 16A, 20A, 25A, kunye ne-32A, okwenza ukuba ilungele iimeko zomthwalo olula ukuya kophakathi. I-CMTB1LE-63, kwelinye icala, yenzelwe imithwalo ephezulu, kunye noluhlu lwangoku lwe-40A, 50A, kunye ne-63A, olugqibeleleyo kwizicelo zamandla aphezulu.

2. Umthamo Wokuqhekeza Izangqa Ezimfutshane: Ii-RCBO zenzelwe ukuphazamisa ngokukhuselekileyo ukuhamba kombane xa kukho i-short circuit. Imodeli ye-CMTB1LE-32 inomthamo wokuqhekeza we-6000A, oqinisekisa ukuqhawuka ngokukhawuleza xa umsinga ugqithisile. I-CMTB1LE-63 inika amandla okuqhekeza ahlukeneyo ngokuxhomekeke kumlinganiselo wangoku: 6000A kwi-40A kunye ne-4500A kwi-50A kunye ne-63A. La mandla aqinileyo enza i-RCBO ithembeke ekuthinteleni umonakalo kwizixhobo zombane ngexesha leemeko zempazamo.

3. Uqwalaselo lweePole: I-RCBO inika ukuguquguquka koqwalaselo lweepole, kuquka ukhetho lwe-1P+N, 2P, 3P+N, kunye ne-4P, nto leyo eyenza ukuba zilungelelaniswe neenkqubo zombane zesigaba esinye kunye nezesigaba sesithathu. Oku kuguquguquka kuvumela uluhlu olubanzi lwezicelo ngelixa kuqinisekiswa ukuba iisekethe zikhuselekile kwi-overload, ii-short circuits, kunye ne-residual currents.

4. Iintlobo zoKhuseleko lwamandla aseleyo: Kukho iintlobo ezimbini zokhuseleko lwamandla aseleyo olunikezelwa yi-RCBO—Uhlobo C kunye noHlobo D, oluyilelwe amandla alinganiselweyo phakathi kwe-3A kunye ne-63A. Uhlobo C lufanelekile kwimithwalo eqhelekileyo, ngelixa uhlobo D luyilelwe imithwalo ephezulu okanye ekwaziyo ukukhupha amandla, njengeemoto okanye izixhobo zoshishino. Oku kuvumela i-RCBO ukuba iphathe iintlobo ngeentlobo zemithwalo ngokufanelekileyo, ithintele ukugqithiswa okanye umonakalo kwinkqubo.

5. Uvakalelo lwangoku olusele: Ii-RCBO zibonelela ngamanqanaba ahlukeneyo ovakalelo kumbane osele, olu luphawu oluphambili lokukhusela ukuvuza. Umbane osele u ...

6. Ixesha Lokuphendula Ngokukhawulezileyo: Xa kufunyenwe impazamo yombane, ii-RCBO zisabela ngokukhawuleza, ixesha lokukhubeka lingaphantsi kwemizuzwana eyi-0.1. Le mpendulo ikhawulezileyo inciphisa umngcipheko womonakalo omkhulu okanye iingozi, inika ukhuseleko oluthembekileyo kwiintlobo ezahlukeneyo zeenkqubo zombane.

Izicelo ze-RCBO

Ii-RCBO zisetyenziswa kakhulu kwiinkqubo zokusasazwa kwe-voltage ephantsi kwiindawo zokuhlala, zorhwebo, nakwimizi-mveliso. Iimpawu zazo zokukhusela ezidibeneyo zenza ukuba zibe yimfuneko kwiimeko zombane zanamhlanje, apho imithwalo eyahlukeneyo neyinkimbinkimbi ixhaphakileyo.

Kwizicelo zasemakhaya, i-RCBO iqinisekisa ukuba izixhobo zombane zasekhaya zikhuselekile kwimisinga yokuvuza, nto leyo ethintela iingozi zokutshayiswa kombane. Kwiindawo zorhwebo, i-RCBO ikhusela izixhobo ezibalulekileyo kunye neziseko zophuhliso kwimiba yombane, iqinisekisa ukuqhubeka kweshishini. Kwizicelo zoshishino, ingakumbi apho kusetyenziswa izixhobo ezifana neemoto kunye noomatshini abanzima, i-Type D RCBO ibonelela ngokhuseleko oluphezulu kwimisinga ephezulu yokungena enokwenzeka ngemithwalo enjalo yokungenisa.
