Ka loina hana o ka moku kaapuni moku

Hoʻohālikelike ʻia me nā mea haʻihaʻi kaʻapuni ʻē aʻe, ʻokoʻa ka loina hana o ka mea haʻihaʻi kaʻapuni ʻokoʻa mai ka mea hoʻopau arc.ʻAʻohe mea conductive i loko o ka vacuum, kahi e pio koke ai ke arc.No laila, liʻiliʻi loa ka mamao ma waena o nā hoʻopili paʻa a me nā paʻa o ka mea haʻihaʻi kaapuni.

ʻO nā hiʻohiʻona hoʻokaʻawale o ka vacuum
Loaʻa i ka vacuum nā hiʻohiʻona insulation ikaika.I loko o nā moku kaapuni moku, he lahilahi loa ke kinoea, he nui ka huakaʻi hele o nā molekele kinoea, a he liʻiliʻi loa ka hopena o ka hui ʻana.No laila, ʻaʻole ʻo ka collision dissociation ke kumu nui o ka haki ʻana o ke ākea ākea, akā ʻo nā ʻāpana metala i hoʻoheheʻe ʻia e ka electrode ma lalo o ka hana o ke kahua uila ikaika loa ke kumu nui e hōʻino ai i ka insulation.
ʻO ka ikaika o ka insulation i loko o ka vacuum gap ʻaʻole pili wale i ka nui o ke āpau a me ke kūlike o ke kahua uila, akā pili pū kekahi i nā waiwai o nā mea electrode a me nā kūlana o ka honua.Ma lalo o ke kūlana o ka liʻiliʻi liʻiliʻi liʻiliʻi (2-3 mm), ʻoi aku ka kiʻekiʻe o nā ʻano insulation ʻoi aku ka nui ma mua o ke ea kiʻekiʻe a me ke kinoea SF6, ʻo ia ke kumu o ka liʻiliʻi o ka wehe ʻana o ka wehe ʻana o ka mea hoʻokaʻawale kaapuni.
Hōʻike nui ʻia ka mana o nā mea electrode i ka voltage breakdown i ka ikaika mechanical (tensile strength) o nā mea a me ka helu heheʻe o nā mea metala.ʻOi aku ka kiʻekiʻe o ka ikaika tensile a me ka helu heheʻe, ʻoi aku ka kiʻekiʻe o ka ikaika insulation o ka electrode ma lalo o ka vacuum.

kumu hana
Ke holo nei ka ea hau māmaele kiʻekiʻe ma ka helu ʻole, hoʻopuehu koke ka plasma a hoʻopau i ke arc e hoʻopau i ke kumu o ka ʻoki ʻana i ke au.
