Ngā whati ara iahiko pouaka whakarewa (MCCB)

Ngā whati ara iahiko kua whakarewaina (MCCB) he mahi nui tā rātou ki te tiaki i ngā pūnaha hiko mai i te taumaha rawa, te pakaru o te ara iahiko poto me te pakaru o te ngaohiko iti. Ko te MCCB raupapa CMTM1 tētahi o ngā MCCB e tū motuhake ana i runga i te pono me te whai hua. He hanganga kiato tēnei kaiwawao ara iahiko kua whakakikoruatia, he iti te rahi me te kaha pakaru teitei, koia te whiringa tuatahi mō ngā whare ahumahi me ngā whare arumoni.

Ko tētahi o ngā āhuatanga matua o ngā pūwhakaweto hiko tauira CMTM1 ko te whānuitanga o ngā whakamahinga. E pā ana ki te ngaohiko whakamahana whakatauranga 400/415/660/690/800/1000V, te auau AC 50/60Hz. Hei tāpiri, kua hangaia hei whakahaere i ngā ngaohiko whakatauranga 690V me raro iho. Nā tēnei ngāwari o te whakamahi, he pai mō te whakamahi i roto i ngā pūnaha hiko maha, kia pai ai te tiaki me te pono.

He iti te rahi o te MCCB CMTM1, ā, he ngāwari te tāuta ki ngā wāhi he iti te wāhi. Nā te iti o te rahi, he pai mō te whakamahi i roto i ngā huihuinga papa whakawhiti me ngā taputapu whakawhiti, he mea nui te nui o te wāhi. Ahakoa tōna hoahoa iti, he nui te kaha pakaru o tēnei MCCB, ka taea te whakakore i ngā ara iahiko poto me te tiaki i ngā taputapu hono.

Ko tētahi o ngā āhuatanga tino pai o te CMTM1 MCCB ko tōna pewa poto. Ina puta he ara iahiko poto, ka tere te tineia e te MCCB te pewa, ka whakaitihia te kino pea. Ka whakaitihia e tēnei āhuatanga te wā kore mahi, ā, ka whakarite kia haere tonu te pakihi, ka waiho hei rawa nui i roto i ngā ahumahi e tino hiahiatia ana te tuku hiko korekore.

Kei roto hoki i te CMTM1 MCCB te whānuitanga katoa o ngā taputapu ā-roto, ā-waho hoki, kia māmā ai te whakarite me te whakauru ki roto i ngā momo pūnaha hiko. Ka whakarei ake ēnei taputapu i te mahi me te mahinga o te MCCB, kia taea ai te whakarerekē ki ngā whakaritenga motuhake, me te whakarite hoki i te tiakitanga pai rawa atu o ngā raina me ngā taputapu hiko.

Hei tāpiritanga, ka tutuki te takahuri hiko CMTM1 i ngā paerewa kua whakatakotoria e IEC60947-2 hei whakarite i te kounga me te haumaru. E mōhiotia ana tēnei paerewa puta noa i te ao, ā, ka oati ka tutuki i ngā hua ngā whakaritenga e tika ana mō ngā pūnaha hiko. Mā te tutuki i tēnei paerewa, ka taea e ngā kaiwhakamahi te okioki mārie me te mōhio kei te tiakina ā rātou pūnaha hiko e ngā MCCB pono me te kounga teitei.

I te katoa, he hua tino pai te takahuri hiko whakarewa raupapa CMTM1 e whakarato ana i te tiakitanga tino pai mō ngā pūnaha hiko. He hanganga kiato, he rahi iti, he kaha pakaru teitei, he pewa poto, he taputapu katoa o roto me waho, ā, he mea hanga kia tutuki ai ngā hiahia o ngā momo ahumahi. He tiakitanga taumaha, ara iahiko poto, tiakitanga ngaohiko iti me ētahi atu mahi hei tiaki i ngā raina me ngā taputapu tuku hiko mai i te kino. Hei tāpiri, e tutuki ana i ngā paerewa IEC60947-2, e whakarite ana i tōna pono me te tutuki i ngā ture haumaru o te ao. Ko te CMTM1 MCCB te whiringa tuatahi mō ngā pakihi me ngā ahumahi e whakanui ana i te tiakitanga hiko whai hua, pono.
