Te rerekētanga i waenga i te MCB me te MCCB

Mō ngā pūwā hiko, e rua ngā kōwhiringa e whakamahia whānuitia ana ko te MCB me te MCCB. Ahakoa e whakamahia ana ēnei hei tiaki i ngā pūnaha hiko mai i ngā taumahatanga me ngā ara iahiko poto, he rerekētanga matua kei waenganui i ngā hua e rua.

Wawahi ara iahiko iti (MCB), e ai ki te ingoa, he mea hanga hei kaiwawao hiko maha-mahi kiato. He whānuitia te whakamahinga i ngā wāhi maha pērā i te ahumahi, te hokohoko, ngā whare teitei, me ngā whare noho. Kua hangaia ngā MCB hei tiaki i ngā waeine tohatoha hiko i roto i ngā whare. He maha ngā momo me ngā rahinga o ngā hua kaiwawao hiko, e tika ana mō ngā tono rerekē.

Ko tētahi o ngā painga matua o te MCB ko tōna kaha ki te whakahaere i te whānuitanga o ngā tawhā hiko. He pai mō te tiaki i te taumaha me te arai poto o ngā raina me te ngaohiko AC 50/60Hz 230/400V me te iahiko kua whakatauria tae atu ki te 63A. Hei tāpiri, ka taea hoki te whakamahi i ngā kaiwawao ara iahiko iti mō te whakawhiti raina i raro i ngā āhuatanga noa. Nā tēnei whakamahinga maha e pai ai mō te maha o ngā pūnaha hiko.

I tētahi atu taha,ngā whati ara iahiko pouaka whakarewa (MCCB) e whakamahia ana i roto i ngā pūnaha tohatoha hiko iti-ngaohiko me ngā ara iahiko tiaki motuka. Ka whakarato i te tiaki i te taumaha me te ara iahiko poto. Ko te āhuatanga matua o te MCCB ko tōna anga kirihou, e mahi ana hei ārai me te wehe i ngā ara iahiko me ngā wāhanga whakarewa whenua. Nā tōna pono me tōna pumau, kua whakamahia whānuitia ngā kaiwawao ara iahiko pouaka whakarewa i roto i ngā ahumahi maha.

Ahakoa he pūwhakawhiti hiko te MCB me te MCCB, he rerekētanga matua kei waenganui i a rāua. Tuatahi, he rerekē ngā tawhā hiko me ngā tawhā miihini. He pai te MCB mō ngā waea tae atu ki te 10 mita pūrua, engari ka taea e te MCCB te hono i ngā waea matotoru ake, pērā i ngā waea neke atu i te 35 mita pūrua. Mā tēnei ka taea e te MCCB te whakahaere i ngā kaha me ngā iahiko teitei ake.

Ko tētahi atu rerekētanga ko te āhua o te hononga. Ko ngā pito o te kaiwawao ara iahiko kua whakakikoruatia he nati, ka taea te pēhi ngāwari, ā, ka pai te hononga. He rerekē, ko ngā MCB he whakamahi i ngā pito kōpeketanga iti ake ka taea anake te whakau mā te tīwiri. Ka pā tēnei rerekētanga o ngā tikanga hononga ki te kounga kōpeketanga me te hononga.

Hei tāpiritanga, he rerekē ngā taiao mahi o te MCB me te MCCB. He maha ngā momo mahi kua hangaia mō ngā MCB, ā, he pai mō te whakamahi i roto i ngā taiao rerekē. Ko te MCCB ia, e whakamahia ana i roto i ngā mahi whakawhiti iti te kaha.

Hei whakarāpopototanga, ahakoa e whakamahia ana ngā pakaru hiko iti me ngā pakaru hiko pouaka pokepoke hei tiaki i ngā pūnaha hiko, he rerekētanga nui kei a rāua. He whānuitia te whakamahinga o te MCB, ā, he whānui hoki ōna whakamahinga, ko te MCCB ia e whakamahia ana i roto i ngā pūnaha tohatoha hiko iti-ngaohiko me ngā ara iahiko tiaki motuka. He rerekē ngā tawhā hiko me ngā tawhā miihini, ngā tikanga hononga me te taiao mahi. Mā te mārama ki ēnei rerekētanga ka āwhina i te whakatau ko tēhea pakaru hiko te mea pai mō ō hiahia.
