RCBOʻO ia ka pōkole o ka "overcurrent residual current circuit breaker" a he mea koʻikoʻi ka palekana uila e hoʻohui i nā hana o kahi MCB (miniature circuit breaker) a me kahi RCD (koena o kēia manawa).Hāʻawi ia i ka pale ʻana i ʻelua ʻano o nā hewa uila: overcurrent a me ke koena o kēia manawa (i kapa ʻia ʻo leakage current).

E hoʻomaopopo peheaRCBOhana, e nānā koke kākou i kēia mau ʻano hemahema ʻelua.

Hiki mai ka overcurrent ke kahe ka au i ke kaapuni, hiki ke ho'oulu i ka wela a me ke ahi paha.Hiki ke hana i kēia no nā kumu like ʻole, e like me ke kaapuni pōkole, ka nui o ke kaapuni, a i ʻole ka hewa uila.Hoʻolālā ʻia nā MCB e ʻike a hoʻopau i kēia mau hewa overcurrent ma o ka hoʻokuʻu ʻana i ke kaapuni i ka wā i ʻoi aku ai ke au i ka palena i koho mua ʻia.

Ma ka ʻaoʻao ʻē aʻe, hiki mai ke koena o kēia manawa a i ʻole leakage ke hoʻopau ʻia kahi kaapuni ma muli o ka uwea maikaʻi ʻole a i ʻole kahi ulia DIY.No ka laʻana, hiki paha iā ʻoe ke hoʻoheheʻe i ke kaula i ka wā e hoʻokomo ai i kahi makau kiʻi a ʻokiʻoki paha me ka mīkini ʻokiʻoki.I kēia hihia, hiki ke kahe ka uila i loko o ke kaiapuni a puni, hiki ke hoʻopuʻi uila a ahi paha.Hoʻolālā ʻia nā RCD, i ʻike ʻia ʻo GFCIs (Ground Fault Circuit Interrupters) ma kekahi mau ʻāina, e ʻike koke i nā au leakage minuke a hele i ke kaapuni i loko o nā milliseconds e pale i kekahi pōʻino.

I kēia manawa, e nānā pono kākou i ka hoʻohui ʻana o RCBO i nā mana o MCB a me RCD.Hoʻokomo ʻia ʻo RCBO, e like me MCB, i ka papa hoʻololi a i ʻole ka mea kūʻai aku.Loaʻa iā ia kahi module RCD i hoʻopaʻa ʻia e nānā mau i ke kahe e kahe ana ma ke kaapuni.

Ke loaʻa ka hewa overcurrent, ʻike ka ʻāpana MCB o ka RCBO i ka nui o ke au a hele i ke kaapuni, no laila ke keʻakeʻa nei i ka lako mana a pale i nā pilikia e pili ana i ka overload a pōkole paha.I ka manawa like, ke nānā nei ka module RCD i kūkulu ʻia i ke koena o kēia manawa ma waena o nā uea ola a kū ʻole.

Inā ʻike ʻia ke koena o kēia manawa (e hōʻike ana i ka leakage hewa), ʻo ka RCBO's RCD element e hele koke i ke kaapuni, no laila e wehe i ka lako mana.ʻO kēia pane wikiwiki e hōʻoia i ka pale ʻana i ka haʻalulu uila a pale ʻia nā ahi hiki ke hoʻemi ʻia, e hōʻemi ana i ka pilikia o nā hewa uea a i ʻole ka pōʻino ulia pōpilikia.

He mea pono e hoʻomaopopo i ka hāʻawi ʻana o RCBO i ka pale kaapuni pākahi, ʻo ia hoʻi ka pale ʻana i nā kaapuni kikoʻī i loko o kahi hale kūʻokoʻa kekahi i kekahi, e like me nā kaapuni kukui a i ʻole nā ​​​​waho.Hiki i kēia pale modular ke ʻike i ka hewa i manaʻo ʻia a me ka hoʻokaʻawale ʻana, e hōʻemi ana i ka hopena ma nā kaapuni ʻē aʻe ke loaʻa kahi hewa.

I ka hōʻuluʻulu ʻana, ʻo RCBO (overcurrent residual current circuit breaker) he mea koʻikoʻi palekana uila e hoʻohui i nā hana o MCB a me RCD.Loaʻa iā ia ka hewa o kēia manawa a me nā hana palekana o kēia manawa e hōʻoia i ka palekana pilikino a pale i nā pōʻino ahi.He kuleana koʻikoʻi ka RCBO i ka mālama ʻana i ka palekana uila i nā hale, nā hale kūʻai a me nā wahi ʻenehana ma o ka holo wikiwiki ʻana i nā kaapuni ke ʻike ʻia kekahi hewa.

E leka mai iā mākou
