He rerekē ngā whakatauranga iahiko e hangaia ana mō ngā kaiwawao iahiko, mai i ngā taputapu hei tiaki i ngā iahiko iahiko iti-iahiko, i ngā taputapu whare takitahi rānei, ki ngā taputapu whakawhiti i hangaia hei tiaki i ngā iahiko ngaohiko teitei e whāngai ana i te tāone katoa.
Ripae hanga ana i te Miniature circuit breaker (MCB) - he iahiko kua whakatauria tae atu ki te 63 A, e whakamahia ana i roto i ngā rama whare noho, arumoni, ahumahi.
Kāore ngā MCB e whakangaromia i te wā e nui haere ana te hiko, nō reira ka taea te whakamahi anō. He māmā ake hoki te whakamahi, e tuku ana i te whai huatanga o te 'whakakā/whakaweto' mō te wehewehe i te ara iahiko, ā, nā te mea kei roto te ara iahiko i tētahi anga kirihou, he haumaru ake te whakamahi me te whakahaere.
Kei te MCBngā āhuatanga matua e toru, arā, ngā Āmpere, ngā Kiro Āmpere me te Piko Whakaheke
Whakatauranga o te Auahatanga Nui - Amperes (A)
Ka puta te taumaha rawa ina he maha rawa ngā taputapu e whakatakotoria ana ki te ara iahiko kotahi, ā, ka nui ake te hiko e tangohia ana i taua ara iahiko me te taura. Tērā pea ka puta tēnei i roto i te kīhini, hei tauira, ina whakamahia ngātahitia te ipu wai, te mīhini horoi rihi, te oumu hiko, te ngaruiti me te mīhini whakaranu. Ka tapahia te hiko e te MCB o tēnei ara iahiko, ā, ka ārai i te wera nui me te mura o te taura me ngā pito.
Ētahi paerewa:
6 Amp- ngā ara iahiko rama paerewa
10 Amp- ngā ara iahiko rama nui
16 Amp me te 20 Amp- Ngā whakamahana me ngā poiha rumaki
32 Amp- Whakamutunga Mowhiti. Ko te kupu hangarau mō tō ara iahiko hiko, ngā tūhono rānei. Hei tauira, he whare moenga rua, tera pea he ara iahiko hiko e 2 x 32A hei wehe i ngā tūhono o runga me raro. Ka taea e ngā whare noho nui ake te whai i te maha o ngā ara iahiko hiko 32 A.
40 Amp- Ngā oumu / ngā oumu hiko / ngā kaukau iti
50 Amp- Ngā kaukau hiko 10kw / Ngā kaukau wera.
63 Amp- te whare katoa
Ka hipokina e ngā Liper Breakers te awhe mai i te 1A ki te 63A
Whakatauranga Ara Poto - Kiro Āmpere (kA)
Ko te ara iahiko poto te hua o tētahi hapa i roto i te ara iahiko hiko, i te taputapu rānei, ā, he nui atu pea te morearea i te taumaha rawa.
Ngā MCB e whakamahia ana i roto ingā whakaurunga ā-wharee arotakehia ana i te nuinga o te wā ki6kA6000 amps rānei. Ko te whanaungatanga i waenga i te ngaohiko noa (240V) me ngā whakatauranga mana o ngā taputapu whare, ko te tikanga kāore te nui o te auhiko i puta mai i te ara iahiko poto e neke ake i te 6000 amps. Heoi, i roto ingā āhuatanga arumoni me ngā āhuatanga ahumahi, ina whakamahi ana i te 415V me ngā mīhini nui, me whakamahi10kAngā MCB kua whakatauria.
Piko Whakaheke
Mā te 'Kōpiko Tūtuki' o te MCB ka taea te kite i ngā pikinga hiko o te ao tūturu, ā, i ētahi wā he mea tino tika. Hei tauira, i roto i ngā taiao arumoni, ko te tikanga me nui ake te pikinga hiko o ngā mīhini nui i tō rātou iahiko e rere ana i te tīmatanga hei wikitoria i te ngoikore o ngā motuka nui. Ka whakaaetia tēnei pikinga poto e te MCB nā te mea he haumaru i roto i te wā poto rawa.
HeNgā Momo Piko Matua e Torue āhei ai ngā ngaru hiko i roto i ngā taiao hiko rerekē:
Ngā MCB Momo Be whakamahia ana i roto itiaki ara iahiko ā-whareina kore e hiahiatia he whakaaetanga mō te ngaru hiko. Ko tētahi ngaru hiko nui i roto i te taiao kāinga he hua pea nō tētahi hapa, nō reira he iti noa te nui o te iahiko nui e whakaaetia ana.
Ngā MCB Momo Cngā haerenga i waenga i te 5 me te 10 ngā wā o te iahiko kawenga katoa, ā, e whakamahia ana i roto ingā taiao arumoni me ngā taiao ahumahi māmākei roto pea ētahi ara iahiko rama hiato nui, ngā whakawhiti hiko me ngā taputapu hangarau mōhiohio pēnei i ngā tūmau, ngā rorohiko me ngā pūreretā.
Ngā MCB Momo De whakamahia ana i roto ingā whare ahumahi taumahapērā i ngā wheketere e whakamahi ana i ngā motuka takai nui, ngā mīhini hihi-X, ngā pūwhakakopeke rānei.
Ka whakaratohia e ngā momo MCB e toru te ārai i te hinganga i roto i te hauwhā o te hēkona. Arā, ina hipa te taumaha rawa me te wā, ka hinga te MCB i roto i te 0.1 hēkona.
Nō reira, ka tutuki i a Liper ō hiahia katoa.
