He aha mea he RCD

Me ka ike ole o ka mea ka RCD (koenaʻikena lima kūlana kiʻekiʻe), e hoʻopaʻa i ka palekana hana o ka pou nā mīkini home mea pilikia. hiki pinepine oe lohe moʻolelo e pili ana i ka pomaikai o ka hoomaemae ana mīkini uila puu hua palaoa ka wā hoopa mai i hana. Ka mea hana ina i ka mea ia manawa hoopa aku i ke kino ka hana kamepiula, a radiators. O kŰia i ola, a me ka meaʻaʻole he malfunction, akā, e aho ka hiʻona o ka pou lako a me ka ili.

Ālai 'hoʻonui i ka pou ae RCD.

He aha mea he RCD? Kēia mea mea he kiʻekiʻe ka māmā holo kaapuni nalu, a ua nānā 'ana i ke kapakai a ka paialewa e hoʻopili like i ka haawe ana, a hele hoʻi ma ka mea ulana pukapuka, ae hana i ka mea e wehe ae kaapuni wā like ole (palena pauʻikena i Konakele.). Ia mea, ina aloha i loko o ka pauku palekana o ka laina e leaking i loko o ka lepo, me ka manaʻo huai ae ia, a de-energize i ka laina.

E noonoo i ka rula o ka RCD. I ka naʻau o ka mea o ka ʻikena mea hoʻololi uila, i kapa palena pau. Ua ninoieo o ekoluʻanuʻu: iniiaiie (L1) a me ka haumāna (L2), niioaaonoaaiii, komo pū i loko o ka pae discontinuities, a'ākilikai nā kaula, a me ke kolu (L3) ua i pili ai i ke kāheaʻano papa hana. Ke kaumaha ma muli o ka hookoʻano papa hana hiki e hoomakaukau me kiʻekiʻe pā lonoaʻili mika (RCD electromechanical type) a lolouila eiiiiiaiou, nō kāu he comparator a me he pahu hoʻonui leo (E-type). Kēia kāheaʻano papa hana ua mechanically hui i ka actuating makou a holo a me ka manaʻoluʻolu o ka hui 'ana.

A hiki aku i ka haawe ua pili i ka RCD ma o Kahualoa Kokohi L1 a me L2, heʻikena lua i pele. No ka mea, i loko o maʻamau hana o ka waiwai o ka pono a pau loa, a hiki i ka consumer like exiting, laila, ua neutralized a me ka mea 'Aʻohe kā lākou mau huinaʻume mākenēki koko ua loaʻa (nāʻanuʻu i pili, he ua kuhikuhi oppositely). Nolaila, i ka'ōwili hao L3 mea i kekahi kanawai. Pololei o ka hana a loa hoʻololi i ka mea ia manawa no i ke kanaka kino i ka lepo, a me kaʻino o ka pa alima ma lalo o anakahi uila. Ma keia hihia, ai ka pae alakaʻi mele (L1 o Kahualoa Kokohi) he houʻikena loa i kaʻikena o Kahualoa Kokohi L2. I ka mea, aia no he like, no ka mea, o ka mea pono e hele ana i loko o ka puni o ka pae alakaʻi mele, e hele aku i loko o ka lepo ma ke kanaka, aʻaʻole hoʻi i ka RCD. Kaʻume mākenēki koko aku i ka compensating'ōwili hao L1 L2 pele hana, niioaaonoaaiii, ua loaʻa ma kaʻume mākenēki koko i ka mea o Kahualoa Kokohi L3 uukuʻikena lawa no ka hoohana ia ana o ka mika a me ka lolouila circuitry a me actuation o ka mea hoʻomaka no ka uhai ana i ka mana hui 'ana.

O ke kanaka ka mea i ike i ka RCD,ʻiʻo ike pehea e hana i kekahi mea kaha o kona hana ana. Ma ka hihia o kekahi RCDs lawe mai i ka "hoao ana" pihi, ke kaomi 'ana i' oe ke hoao aku i ka functionality o ka noonoo o kanaka. Ua e komo shunts kekahi o nāʻanuʻu, ae hookaawale ia ia mai ka huakai kaapuni ua loaʻa ma ka ukuʻume mākenēki koko, no laila, i ka mea ua triggered.

A nani nīnau - pehea e hoʻohui i ka RCD? Ka mea Ua e e lele aku ma ka tandem me ka 'akomi kuapo, no ka mea, aole ia i apo ia i ka thermal a me ka electromagnetic a ke hookuu aku oia, niioaaonoaaiii,' aʻole e hoomalu nae lakou i ku e overload (thermal) a me kiʻekiʻe-ʻikena pōkole-kaapuni (HI). Hoohewaʻeʻikena e hanaʻino i ka RCD, e like me ia ma keia ano o ka hana i ke kulu, aole ia i hana, akā, ua mahuahua no ka i lanakila maluna o Hawaiʻi i kaʻikena cia. Ma ke ala, keia mea ke kumu i mea nui ka wā kūʻai i ka pua paha me ka RCD Loipālākiōʻikena e koho. No ka laʻana, ina ka mīkini ua manao ia no ka 16 Amp, pono e ole e emi malalo o 25 amperes ka RCD. Ma na mea hua'ōlelo, ka Loipālākiō pono o ka RCD - Ua ana pono no na eiiiiiaiou o kona conductors.

ʻae nō hoʻi, i loko o ko makou manawa, ia mea pono ole wale, e ike i ka ninau, i mea ka RCD, akā, no hoi e hiki ke hana ia i loko o kou mau wahi. Ma hope o nā mea a pau, keia mea he hou e malu ai no nā 'ohana.
