ʻO Kina ka mea hoʻolako o ke koena o kēia manawa kaapuni breaker me ka overcurrent pale

E kohoCDADAe like me kāu mea hana a mea hoʻolako. Ma muli o Kina, hāʻawi mākou i ka Residual Current Circuit Breaker me ka Overcurrent Protection, a me kahi ākea o nā mea uila haʻahaʻa haʻahaʻa. Hiki iā mākou ke hoʻomohala i nā ʻoihana loea, hoʻoponopono i kūpono i kāu mau koi papahana; hele mai kā mākou huahana me kahi palapala hōʻoia 3 makahiki a hoʻokō i nā kūlana honua like ʻole.

He aha ka RCBO?

ʻO RCBO (Residual Current Circuit Breaker with Overcurrent Protection) he polokalamu modular e hoʻohui i nā hana o kahi MCB (Kaapuni Kaapuni liʻiliʻi)a me kahi RCCB (Residual Current Circuit Breaker).

ʻOiai ke pale wale nei ka MCB i nā kaula mai ka wela (overload) a me ka pōʻino pōʻino (pōkole kaapuni), a ʻo RCCB wale nō ke pale i ke kanaka mai ka haʻalulu (leakage), na ka RCBO e hana i nā mea āpau. Inā loaʻa kahi hewa—inā paha he piʻi nui mai kahi kaapuni pōkole a i ʻole kahi liʻiliʻi liʻiliʻi ma ke kino o ke kanaka—e holo ana ka RCBO, e hoʻokaʻawale koke i ke kaapuni. Hana ʻia kēia mana ʻelua i ke kūlana gula no nā hale noho hou a me nā hoʻonohonoho uila.

Nā ʻano a me nā hoʻohālikelike

ʻO kā mākou hana hana RCBO e uhi i kahi ākea ākea o nā hoʻonohonoho ʻenehana e hoʻokō i nā koi mākeke honua.

Nā hana kumu a me nā mīkini pale

He mea kupanaha ka RCBO o ka miniaturization, hale ʻelua ʻōnaehana pale ʻokoʻa i loko o kahi pahu hoʻokahi.

Palekana ʻOi aku (The MCB Component):

Huakaʻi Thermal: Hoʻomaʻamaʻa ʻia kahi kaula bimetallic a piʻo ma lalo o ka haʻahaʻa paʻa, wehe ʻia ka mīkini. Mālama kēia i nā kaula mai ka heheʻe.

Kaahele Magnetic: Hana ka wili solenoid i nā kaʻa kaʻa pōkole kiʻekiʻe, e hoʻohiolo i ka mea haʻihaʻi i nā milliseconds e pale ai i ka pahū a i ʻole ke ahi.

Palekana o kēia manawa (The RCCB Component):

Transformer-Sequence Zero: Mālama mau i ke koena ma waena o nā au Live a me Neutral.

ʻIke Leakage: Inā hāʻule kēia manawa i ka honua (e laʻa, ma o ke kanaka), hoʻomaka ke kaulike ʻole i kahi relay koʻikoʻi e wehe ai i nā pilina.

Palekana Hui: Ua hoʻolālā ʻia ka mīkini i loko i hiki i nā ʻōnaehana (thermal/magnetic A i ʻole ke koena) ke hoʻomaka i ka latch huakaʻi, me ka hōʻoia ʻana ʻaʻohe hewa e ʻike ʻole ʻia.

Nā noi mua a me nā hihia hoʻohana

Hoolaha Noho: Ka pale ʻana i nā kaapuni pākahi (e laʻa, nā kumu kīhini, nā mea hoʻomehana lumi ʻauʻau) kahi e koi ʻia ai ka pale kaumaha a me ka haʻalulu i loko o kahi ākea panel.

Na Hale Kalepa: E hōʻoia ana i ka hoʻomau o ka lawelawe. Inā loaʻa kahi hewa ma kahi kaapuni (e laʻa, he PC hewa), ʻo kēlā mau huakaʻi RCBO kikoʻī wale nō, ma mua o kahi RCCB nui e ʻoki i ka mana i ka papahele holoʻokoʻa.

Hiki ke hoʻololi hou ʻia (Solar PV): Ka pale ʻana i nā kaapuni inverter mai nā hewa hoʻoheheʻe DC a me nā ʻauwaha nui.

Ka Mana Hana: Ka pale ʻana i nā kaʻa kaʻa a me nā kaʻa mai nā hemahema o ka pae a i ka honua.

Hana Pono: Mai nā mea maka a i ka huahana i pau

ʻOi aku ka paʻakikī o ka hana ʻana i kahi RCBO ma mua o ka hana ʻana i kahi MCB a i ʻole RCCB kaʻawale, no ka mea, pono ia i ka hoʻonohonoho pono ʻana o nā ʻano hana ʻelua.

1. Nā Mea Makaʻu Nui:

hale: ʻO Polyamide (PA66) a i ʻole Polycarbonate no ka pale ʻana i ka wela i hana ʻia e nā mea pale ʻelua.

Pūnaehana Hoʻokaʻaʻike: Silver-Tin-Oxide (AgSnO2) contact hiki ke lawelawe i na au a me ka hoololi pinepine ana.

Koko Magnetic: Permalloy a Nanocrystalline core no ka mea hoʻololi ʻike leakage.

Hui Kaʻahele: He hui paʻakikī e hui pū ana i kahi bimetallic strip, solenoid coil, a me ka polarized magnetic relay.

2. Ka Hana Hana Hana Hana:

ʻAhaʻi ʻAha: Ua hui ʻia ka mīkini MCB (thermal/magnetic) a me ka mīkini RCCB (transformer/relay) ma nā laina ʻokoʻa.

Hoʻohui: Hoʻohui ʻia nā ʻōnaehana ʻelua. Hoʻopili ʻia ka "trip bar" i hiki i ka ikaika mechanical mai ka overload a i ʻole ka ʻike leakage hiki ke wehe maikaʻi i nā pilina.

Ueaea: Hoʻopili ʻia nā mea hoʻopili hikiwawe i loko me ka pololei e hōʻoia i ka haʻahaʻa haʻahaʻa a me ka maʻalahi mechanical.

Hoʻolālikelike ʻelua: ʻO kēia ka hana koʻikoʻi loa. Hoʻāʻo ʻia ka ʻāpana no Amperage (In) (e.g., 16A) a me Leakage (IΔn) (e.g., 30mA). Pono e hoʻopili pono ʻia nā mea ʻelua no ka hele ʻana o ka ʻāpana.

Ka Mana Koʻikoʻi a me nā Kūlana Hoʻāʻo

Hoʻopili mākou i ka IEC/EN 61009-1, ke kūlana honua no nā RCBO. Ua pau kā mākou hoʻāʻo ʻana no ka mea lawe ka hāmeʻa i ke kaumaha o ʻelua mau hana palekana.

Nā mea ho'āʻo maʻamau a me nā koina nānā hale hana:

ʻO kā mākou Hana Hana: Laina, Lako, a me ka Hui

Hoʻolālā ʻia kā mākou hale hana e mālama i ka paʻakikī o ka hui RCBO me ka pololei kiʻekiʻe.

Laina Hana Hana: Hoʻohana mākou i nā laina hui modular e ʻae ai i ka hui like ʻana o nā ʻāpana MCB a me RCCB ma mua o ke kahua hoʻohui hope.

Mea Hana Kiʻekiʻe:

Nā Papa Hoʻolāʻau Kānāwai ʻElua: Nā mīkini kūikawā e hoʻāʻo like i ka helu overcurrent (Amps) a me ke koena o kēia manawa (mA) e hōʻoia i ka holo pono ʻana o nā ʻōnaehana ʻelua.

Nā lopako wiliwili ʻakomi: No ka uwea kūloko pololei, e hoemi ana i ka pilikia o na hookui wehe i mea ko'iko'i i loko o ia mea pa'i.

Nā Kiʻi Paʻi Kiʻekiʻe: Hoʻohana ʻia i ka R&D no ka ʻike ʻana i ka hoʻokaʻawale ʻana i ka pilina ma ka huakaʻi no ka hoʻomaikaʻi ʻana i ka mīkini hoʻopili.

Hui Pūʻali:

ʻEnekinia Hoʻohui: ʻO ka poʻe loea i ka hoʻolālā pili mechanical, e hōʻoia ana i ka holo ʻana o ka "trip logic" me ka hala ʻole inā he haʻahaʻa a leak paha ka hewa.

Mana maikaʻi: Hoʻomaʻamaʻa ʻia e ʻike i nā pilikia "nuisance tripping" a hōʻoia i ka pale ʻana o ka hāmeʻa i nā piʻi uila ʻaʻole ia he hewa.

E koho i kā mākou RCBO. Hāʻawi mākou i kahi huahana e hāʻawi i ka pale kiʻekiʻe ma kahi liʻiliʻi loa, i hana ʻia no kahi honua e koi ana i ka palekana a me ka pono.
