ʻO ka hoʻohālikelike kumu nui o nā mea hoʻokele kaapuni-ACB MCCB MCB

Kaapuni kaapuni, i hāʻule i ʻekolu mau ʻāpana ākea.

Kapa ʻia ke ʻano muakaapuni kaapuni eaor kaapuni kaapuni ea.ʻO ka hōʻailona no kahi Frame BreakerACB, no ka mea, he Kaapuni ka huaolelo Air a he Breaker ka huaolelo Breaker.

ʻO ke ʻano ʻelua, i kapa ʻiapahu hoʻoheheʻe kaʻapuni, heMCCB;
ʻO ke ʻano ʻekolu kaliʻiliʻi kaʻapuni breaker, nona ka hoailonaMCB.

ʻO ka laulā i koho ʻia i kēia manawa oACB mai 1250A a 6300A, ka palena kiʻekiʻe loa o kēia manawa;ʻO ka laulā i koho ʻia i kēia manawa oMCCB mai 10A a 1600A, me ka helu o kēia manawa i waena.ʻO ka MCB ka liʻiliʻi loa o ka pae helu o kēia manawa, mai 6A a 63A, akā ʻo ia ke kumu nui o nā mea hoʻokele kaapuni home.
No kēlā ʻano ʻano, hilinaʻi ka insulation ma waena o nā mea hoʻopili i loko o ka mea haʻihaʻi kaapuni, ʻo ia hoʻi ke kumu i ʻike mau ʻia ai ka MCB ʻo ka hoʻololi ea.
No ka mea e pili ana ka insulation ma waena o nā mea hoʻopili i loko o ka circuit breaker i ka ea, pono mākou e kūkākūkā i nā ʻano haʻihaʻi o ka ea, a me kekahi ʻike kumu o ka arc.

2. E pili ana i ka arc

ʻIke mākou i ke arc me he ao o ke kinoea wela.I loko o ke arc, ma nā mahana ma luna o 3,000 degere, pakele nā ​​electrons mai nā ʻātoma e hana i nā ion maikaʻi ʻole, ka mea i nalowale i ka plasma a pau nā molekole ea, kahi hui o nā electrons a me nā kinoea ionic maikaʻi.

3. Ka mamao wehe o ke kaapuni kaapuni

ʻO ka mea hoʻokaʻawale kaapuni Frame ACB, ʻo ka mamao pōkole loa ma waena o ka neʻe ʻana a me ka pilina paʻa i kapa ʻia he mamao hāmama.
Hoʻohana ʻia ka mamao wehe no ka hōʻoia ʻana ʻaʻole e hoʻopau ʻia ka ea ma waena o nā mea hoʻopili hāmama.
