Te Tātari i te Mahi me te Whakamahinga o te MCB Circuit Breaker

Ngā whati ara iahiko itiHe wāhanga nui ngā MCB (Mīhini Whakamātautau Hiko) i roto i ngā pūnaha hiko hou, e whakarato ana i te tiakitanga nui mai i ngā taumahatanga me ngā ara iahiko poto. I te mea ka piki haere te hiranga o te haumaru hiko i roto i ngā taiao noho me ngā taiao arumoni, he mea nui te mārama ki ngā mahi me ngā painga o ngā MCB mō te hunga katoa e uru ana ki te tāutanga, ki te tiaki rānei i ngā hiko.

He aha te MCB?

Ko te kaiwawao hiko iti (MCB) he taputapu hiko-ā-ringa i hangaia hei whakakore aunoa i te hiko ina kitea he hapa, pērā i te taumaha rawa, te poto rānei o te hiko. He rerekē ki ngā fiusi tuku iho, me whakakapi i muri i te pakaru, ka taea te tautuhi anō i ngā MCB i muri i te pakaru, ā, he pai ake, he whai hua ake hoki mō te tiaki hiko.

Te mahi a te MCB

Ko te mahi a ngā kaiwawao hiko iti (MCB) e ahu mai ana i ngā tikanga e rua: te wera me te aukume. Ka whakamahia e te tikanga wera he rīpene whakarewa-rua e piko ana hei whakautu ki te taumaha rawa, ā, ka puta he pana hei whakatuwhera i te ara iahiko. Ko te tikanga aukume, i tetahi atu ringa, ka whakautu ki te āhua poto-ara iahiko mā te whakamahi i te aukume hiko e whakatuwhera ana i te pana tata tonu, ka ārai i te kino o te pūnaha hiko.

Ngā momo MCB

He maha ngā momo MCB, ia momo i hangaia mō tētahi tono motuhake:

1. Ngā whati ara iahiko iti Momo B:He pai mō ngā mahi kāinga, ka taea e rātou te tu atu i ngā iahiko piki me te heke. Ko te iahiko whakataka he 3 ki te 5 ngā wā o te iahiko whakatauranga.
2. Ngā Wāhi Whakaweto Ara Iahiko Iti Momo C**:He pai rawa ngā whati hiko iti Momo C mō ngā mahi arumoni me ngā mahi ahumahi, ā, ka taea hoki e rātou te tu atu i ngā iahiko nui ake, he mea pai mō ngā taputapu pēnei i ngā motuka me ngā whakawhiti hiko. He 5 ki te 10 ngā wā o te iahiko whakatauranga o te iahiko kua whakatauria.
3. MCB Momo-D:Kua hangaia ēnei whati hiko mō ngā tono taumaha, pērā i ngā motuka nui me ngā whakawhiti hiko, ā, ka taea te whakahaere i ngā iahiko tomo mai 10 ki te 20 ngā wā o te iahiko kua whakatauria.
4. MCB Momo-K me te Momo-Z:He MCB motuhake ēnei e whakamahia ana mō ngā tono motuhake, pērā i te tiaki i ngā kawenga capacitive, i ngā taputapu hiko tairongo rānei.

Ngā painga o te whakamahi i te MCB

1. Haumaru:He haumaru ake ngā pakaru hiko iti i ngā fiusi. Ka taea e rātou te momotu tere i te hiko mēnā he hapa, ka whakaiti i te tūponotanga o ngā ahi hiko me ngā pakaru taputapu.
2. Ngāwari:He rerekē ki ngā fiusi e hiahia ana kia whakakapia i muri i te pakaru, ka taea te tautuhi anō i ngā MCB mā te pana noa iho, kia iti ai te wā kore mahi me te mahi tiaki.
3. Tika:Ka tukuna e ngā MCB ngā tautuhinga tiaki tika, e whakarato ana i ngā otinga kua whakaritea i runga i ngā hiahia motuhake o ngā pūnaha hiko.
4. Hoahoa Kiato:He iti ake, he kiato ake hoki ngā MCB i ngā fiusi tuku iho, ā, he māmā ake te tāuta ki ngā wāhi kuiti.
5. Whai hua te utu:Ahakoa he nui ake te haumitanga tuatahi ki ngā MCB i ngā fiusi, nā te roa o te ora me te iti o ngā utu tiaki, he kōwhiringa ohanga ake ēnei mō te wā roa.

Te Tāutanga me te Tiaki

He mea nui te tāutanga me te tiaki tika o ngā MCB hei whakarite i tōna whai huatanga. Me whakarite kia whiriwhiria te momo MCB e tika ana i runga i ngā whakaritenga kawenga, ā, me tāuta kia rite ki ngā ture hiko ā-rohe. Me tirotiro auau kia tika ai te mahi a te MCB, ā, kāore he tohu o te pakaru, o te pakaru rānei.

He aha te rerekētanga i waenganui i te MCB me te MCCB?

Tuatahi, ko ngā MCB te nuinga o te wā e whakamahia ana mō te tiaki i te ara iahiko poto me te taumaha nui mai i ngā iahiko iti (i raro iho i te 100 amperes te nuinga), ko ngā MCCB ia e whakamahia ana mō te tiaki i te ara iahiko poto me te taumaha nui mai i ngā iahiko teitei (i runga ake i te 100 amperes te nuinga). Nā ngā hoahoa hanganga me ngā rauemi rerekē e whakamahia ana e ngā MCB me ngā MCCB hei whakauru i ngā iahiko me ngā kawenga rerekē. Tuarua, ko ngā MCB te nuinga o te wā e whakamahi ana i ngā wāhanga hiko pēnei i ngā wiwi me ngā whakawhiti wera hei tiaki, ko ngā MCCB ia e whakamahi ana i ngā taputapu miihini pēnei i ngā parenga aukume-wera.

Hei whakarāpopototanga

He kupu ngāwari noa iho, he mea nui te mahi a ngā kaiwawao hiko iti (MCB) ki te tiaki i ngā pūnaha hiko mai i ngā taumahatanga me ngā ara iahiko poto. Nā te kaha ki te whakarato i te tiakitanga tere me te pono, me te whai hua me te whai hua o te utu, ka waiho hei wāhanga nui i roto i ngā whakaurunga hiko kāinga me ngā arumoni. I te haere tonu o te whanaketanga o te hangarau, ka piki haere te hiranga o ngā MCB ki te whakarite i te haumaru hiko, ā, he mea nui kia mārama ngā tohunga me ngā kaipupuri whare ki ō rātou kaha me ngā painga.
