A Mea haki kaapunihe mea hoʻololi e hiki ke ʻoki ponoʻī i ke au ke loaʻa i kahi kaapuni ka overload, kaapuni pōkole a i ʻole nā ​​​​kūlana ʻē aʻe, e pale ana i ke kaapuni a me nā lako. Wahi a ke kaiapuni hoʻohana, ke kumu hana a me ka pae voltage, hiki ke hoʻokaʻawale hou ʻia nā mea haki kaapuni i kekahi mau ʻano:

Hoʻokaʻawale ʻia e ka uila hana
Nā mea haki kaapuni haʻahaʻa-voltage (LV): Hoʻohana ʻia lākou i nā kaapuni home, kalepa a me nā ʻoihana māmā, me ka voltage maʻamau ʻaʻole iʻoi aku ma mua o 1000V. Mālama nui lākou i nā kaapuni a me nā lako uila. ʻO nā ʻano maʻamau e komo pū me nā mea haki kaapuni miniature (MCB) a me nā mea haki kaapuni hihia i hoʻoheheʻe ʻia (MCCB).
Nā mea haki kaapuni uila kiʻekiʻe (HV): Hoʻohana ʻia lākou i nā ʻōnaehana ʻoihana, hoʻoili mana a me ka hāʻawi ʻana, me nā uila ma luna o 1kV. Hiki iā lākou ke ʻoki i nā au nui a pale i ka palekana o nā pūnaewele mana. ʻO nā ʻano maʻamau e komo pū me nā mea haki kaapuni aila, nā mea haki kaapuni i hoʻopaʻa ʻia i ke kinoea (GIS), a me nā mea haki kaapuni vacuum.
E hoʻokaʻawale ma ke ʻano hoʻopau ʻāʻī
Mea haki kaapuni ea (ACB): Hoʻohana ia i ka ea ma ke ʻano he mea hoʻopau arc a kūpono no nā kaapuni uila waena a me haʻahaʻa.
ʻO ka mea haki kaapuni vacuum (VCB): Hoʻopau ʻia ke kinai ʻana o Arc i loko o kahi ʻano vacuum, kūpono no ka hana alapine kiʻekiʻe a me ke ola lawelawe lōʻihi.
Mea haki kaapuni ʻaila (OCB): Hoʻohana ia i ka ʻaila ma ke ʻano he mea hoʻopau arc a kūpono ia no nā laina uila kiʻekiʻe.
Mea haki kaapuni kinoea (SF6 CB): Ke kinai ʻana i ke arc me ke kinoea sulfur hexafluoride, kūpono no nā ʻōnaehana voltage kiʻekiʻe a me nā ʻōnaehana voltage kiʻekiʻe loa.
Hoʻokaʻawale ʻia e ka hoʻohana ʻana
Mea haki kaapuni pale: Hoʻohana nui ʻia no ka palekana overload a me ka pale kaapuni pōkole.
ʻO ka mea haki kaapuni ʻano mana: Hoʻohana ʻia no ka kaohi ʻana o nā kaapuni a he hana pale nō hoʻi.

ʻAʻole wale nā ​​​​mea haki kaapuni e pale aku i nā lako kaapuni mai ka hōʻino ʻia, akā e hōʻoiaʻiʻo hoʻi i ka palekana o nā limahana, hoʻonui i ka hilinaʻi a me ke kūpaʻa o ka hana ʻōnaehana, a he mau mea nui ia i nā ʻōnaehana mana hou a me ka automation ʻoihana.
