ʻO ke ʻano o nā ʻano like ʻole i loko o ka pūpū o ka mea haki kaapuni hihia i hoʻoheheʻe ʻia (MCCB)

Nā mea haki kaapuni hihia i hoʻoheheʻe ʻia (MCCB) he mau ʻāpana koʻikoʻi i nā pūnaewele hoʻokaʻawale mana, e hāʻawi ana i ka pale ʻana i nā kaapuni pōkole a me nā overloads. He mea nui ka hoʻomaopopo ʻana i nā ʻano like ʻole i loko o ka pā MCCB e hōʻoia i ka hana kūpono a me ka palekana o ka ʻōnaehana uila.

ʻO ke anakahi uila i helu ʻia ʻo Ue ka anakahi uila o ka ʻōnaehana, ʻo ia hoʻi he 5% kiʻekiʻe ma mua o ke anakahi uila ma ke kau uila. Ua hoʻolālā ʻia ka mea haki kaapuni hihia plastik e hana me kahi anakahi uila kū i ka impulse i helu ʻia ʻo Uimp=12KV a me kahi anakahi uila insulation i helu ʻia ʻo Ui 400V. Pono e hoʻomaopopo ʻia ʻaʻole pono e ʻoi aku ka nui o ke anakahi uila o ka pūnaewele hoʻolaha ma mua o ke anakahi uila insulation i helu ʻia ʻo Ui e pale aku i kekahi pōʻino hiki.

ʻO ka helu o kēia manawa o 125 Amp e hōʻike ana i ka mana lawe o kēia manawa kiʻekiʻe loa o ka MCCB. Eia kekahi, ʻo ka palena hana koke o kēia manawa ʻo Ii o ka hoʻokuʻu magnetic he 10In, kahi ʻo In he 10 manawa o ke au i helu ʻia (1250A), e hōʻoiaʻiʻo ana i ka hana wikiwiki a me ka maikaʻi ma lalo o nā kūlana kaapuni pōkole.

Ma ka ʻaoʻao ʻākau o ka pūpū haki kaapuni hihia i hoʻoheheʻe ʻia, ʻo ka palena helu o ka mana hoʻokaʻawale pōkole pōkole Icu=35KA a me ka helu helu o ka mana haki kaapuni pōkole hana Ics=22KA e hōʻike ana i ka hiki o ka mea haki kaapuni hihia i hoʻoheheʻe ʻia e lawelawe i nā kūlana kaapuni pōkole me ka ʻole o ka hoʻopilikia ʻana i ka palekana. Ua hoʻolālā ʻia ʻo MCCB e loaʻa kahi pae mahana hana o -5°C a 40°C a me ke alapine o 50/60 Hz, e kūpono ai no nā ʻano kūlana kaiapuni like ʻole.

Eia kekahi, ua kūlike ʻo MCCB me nā kūlana hana IEC/EN60947-2, e hōʻoiaʻiʻo ana i ka mālama ʻana i nā lula maikaʻi a me ka palekana. Hoʻoikaika kēia kūlana i ka hilinaʻi a me ka hana o MCCB, e hāʻawi ana i nā mea hoʻohana i ka maluhia o ka noʻonoʻo e pili ana i kona pono hana a me ka lōʻihi o ka lōʻihi.

I ka hōʻuluʻulu manaʻo, ʻo ka hoʻomaopopo ʻana i nā palena i loko o ka pā MCCB he mea nui ia no ke koho ʻana i ka mea pale kaapuni kūpono no ka ʻōnaehana uila. Me kona hoʻolālā paʻa a me ka hoʻokō ʻana i nā kūlana hana, hōʻoia ʻo MCCB i ka hana palekana a hilinaʻi hoʻi i nā ʻano hana like ʻole.
