Hana ʻia nā mea haʻihaʻi kaapuni ma nā helu ʻokoʻa o kēia manawa, mai nā mea hana e pale ai i nā kaapuni haʻahaʻa a i ʻole nā mea hana hale pākahi, a hiki i nā mea hoʻololi i hoʻolālā ʻia e pale i nā kaapuni kiʻekiʻe e hānai ana i ke kūlanakauhale holoʻokoʻa.
Liperhana ʻo Miniature circuit breaker (MCB) - helu ʻia i kēia manawa a hiki i 63 A, i hoʻohana pinepine ʻia i ka hale noho, kālepa, kukui ʻoihana.
ʻAʻole hoʻopau ʻia nā MCB i ka wā o ka over-current no laila hiki ke hoʻohana hou ʻia. ʻOi aku ka maʻalahi o ka hoʻohana ʻana, e hāʻawi ana i ka ʻoluʻolu o ka 'on/off switch' no ka kaʻawale kaʻapuni a no ka mea aia ke alakaʻi i loko o kahi pahu plastik, ʻoi aku ka palekana o ka hoʻohana a me ka hana.
Aia ka MCBʻekolu mau ʻano kumu, ʻo Amperes, Kilo Amperes a me Tripping Curve
Kaumaha o kēia manawa - Amperes (A)
Loaʻa ka hoʻouka ʻana ke kau ʻia nā mea hana he nui ma ke kaʻapuni hoʻokahi a huki i ke au uila ʻoi aʻe ma mua o kēlā kaapuni a me ke kaula i hoʻolālā ʻia e lawe. Hiki i kēia ke hana i loko o ka lumi kuke, no ka laʻana, ke hoʻohana ʻia ka ipu hao, ka mea holoi ipu, ka umu uila, ka microwave a me ka huila i ka manawa like. ʻOki ka MCB ma kēia kaapuni i ka mana no laila e pale ai i ka wela a me ke ahi i loko o ke kaula a me nā hopena.
ʻO kekahi mau kūlana:
6 Amp- nā kaapuni kukui maʻamau
10 Amp- nā kaapuni kukui nui
16 Amp a me 20 Amp- Nā mea hoʻomehana a me nā paila
32 Amp- Ring Hope. ʻO ka huaʻōlelo ʻenehana no kāu kaapuni mana a i ʻole nā kumu. ʻO kahi hale lumi moe ʻelua, no ka laʻana, loaʻa iā 2 x 32A mau kaapuni mana e hoʻokaʻawale i nā kumu o luna a me lalo. Hiki ke loaʻa i nā hale ʻoi aku ka nui o nā kaapuni 32 A.
40 Amp- ʻO nā kīʻaha / ʻuʻu uila / ʻauʻau liʻiliʻi
50 Amp- 10kw ʻauʻau uila / ʻauʻau wela.
63 Amp- ka hale a pau
Hoʻopili ka Liper Breakers i ka laulā mai 1A a 63A
Kaapuni Pokole - Kilo Amperes (kA)
ʻO ke Kaapuni Pōkole ka hopena o ka hewa ma kahi o ke kaapuni uila a i ʻole ka mea hana a ʻoi aku paha ka pōʻino ma mua o ka hoʻonui.
Hoʻohana ʻia nā MCB manā mea hoʻonoho halehelu pinepine ʻia ma6kAa i ʻole 6000 amps. ʻO ka pilina ma waena o ka uila maʻamau (240V) a me nā helu mana o nā mea hana hale maʻamau, ʻaʻole pono e ʻoi aku ka nui o ka manawa i hana ʻia e ke kaapuni pōkole ma mua o 6000 amps. Eia naʻe, maʻoihana a me nā kūlana ʻoihana, i ka wā e hoʻohana ai i ka 415V a me nā mīkini nui, pono e hoʻohana10kAhelu ʻia nā MCB.
Kaʻahele ʻAha
ʻO ka 'Tripping Curve' o kahi MCB e hiki ai i ka honua maoli a i kekahi manawa pono loa, piʻi i ka mana. No ka laʻana, nā kaiapuni ʻoihana hale, nā mīkini nui e koi pinepine i ka piʻi ʻana o ka mana ma mua o ko lākou holo ʻana maʻamau e lanakila ai i ka inertia o nā kaʻa nui. ʻO kēia haʻalulu pōkole e mau kekona wale nō, ʻae ʻia e ka MCB no ka mea palekana i ka manawa pōkole loa.
Aiaʻekolu kumukānāwai Nā ʻano Pipie ʻae ai i nā piʻi ʻana ma nā wahi uila like ʻole:
ʻAno B MCBshoʻohana ʻia mapale kaapuni halekahi liʻiliʻi e pono ai ka ʻae ʻana i ka piʻi ʻana. ʻO ka piʻi nui ʻana i loko o kahi kaiapuni home ma muli paha o kahi hewa, no laila he liʻiliʻi ka nui o ke au i ʻae ʻia.
ʻAno C MCBnā huakaʻi ma waena o 5 a me 10 mau manawa piha piha i kēia manawa a hoʻohana ʻia iʻoihana pāʻoihana a māmāhiki ke hōʻike i nā kaapuni kukui fluorescent nui, nā mea hoʻololi a me nā lako IT e like me nā kikowaena, nā PC a me nā mea paʻi.
ʻAno D MCBhoʻohana ʻia manā hale hana kaumahae like me nā hale hana e hoʻohana ana i nā kaʻa uila nui, nā mīkini X-ray a i ʻole nā compressors.
Hāʻawi nā ʻano MCB ʻekolu i ka pale ʻana i ka hele ʻana i loko o ka hapaʻumi o kekona. ʻO ia hoʻi, ke ʻoi aku ka nui o ka ukana a me ka manawa, holo ka MCB i loko o 0.1 kekona.
No laila, hoʻokō mau ʻo Liper i kāu mau pono āpau.
