ʻIkepili o nā ʻano RCD

ʻO nā mea hana o kēia au hou (RCD) he mau mea palekana koʻikoʻi i hoʻolālā ʻia e pale aku i ka haʻalulu uila a me nā pōʻino ahi i nā hoʻonohonoho uila. Nānā lākou i ke kaulike o ke au uila e komo ana a e puka ana i kahi kaapuni, a inā ʻike lākou i kahi ʻokoʻa, hoʻokaʻawale koke lākou i ka lako mana e pale aku i ka pōʻino. ʻElua ʻano nui o nā RCD: ʻAno A a me ʻAno B, kēlā me kēia me kāna mau hiʻohiʻona a me nā noi ponoʻī.

Nā RCD ʻAno A
ʻO nā RCD ʻAno A ke ʻano maʻamau a ua hoʻolālā ʻia e hāʻawi i ka pale ʻana i nā kahe AC sinusoidal, pulsating DC, a me nā kahe koena DC maʻemaʻe. He kūpono lākou no ka hoʻohana ʻana ma ka hapa nui o nā wahi noho a me nā ʻoihana kahi i maʻalahi ai nā ʻōnaehana uila, a haʻahaʻa ka pilikia o ka hālāwai ʻana me nā kahe non-sinusoidal a i ʻole pulsating.
ʻO kekahi o nā hiʻohiʻona koʻikoʻi o nā RCD ʻAno A ʻo ko lākou hiki ke ʻike a pane i nā kahe koena DC pulsating, i hana pinepine ʻia e nā lako uila e like me nā kamepiula, nā TV, a me nā kukui LED. ʻO kēia ka mea e kūpono ai lākou no ka hoʻohana ʻana i nā hoʻonohonoho uila hou kahi i nui ai kēlā mau lako.

Nā RCD ʻAno B
Hāʻawi nā RCD ʻAno B i kahi pae kiʻekiʻe o ka palekana i hoʻohālikelike ʻia me nā mea hana ʻAno A. Ma waho aʻe o ka hāʻawi ʻana i ka palekana mai nā kahe sinusoidal AC, pulsating DC, a me nā kahe koena DC maʻemaʻe e like me nā RCD ʻAno A, hāʻawi pū lākou i ka palekana mai nā kahe koena DC maʻemaʻe. ʻO kēia ka mea e kūpono ai lākou no ka hoʻohana ʻana i nā wahi kahi i ʻoi aku ai ka pilikia o ka hālāwai ʻana me nā kahe DC maʻemaʻe, e like me nā wahi ʻoihana, nā hoʻonohonoho photovoltaic (mana solar), a me nā kikowaena hoʻouka kaʻa uila.
He mea koʻikoʻi ka hiki o nā RCD ʻAno B ke ʻike a pane i nā kahe koena DC maʻemaʻe i ka hōʻoia ʻana i ka palekana o nā kikowaena uila e hoʻohana ana i nā kumu mana DC. Me ka ʻole o kēia palekana, aia kahi pilikia o ka haʻalulu uila a i ʻole ke ahi, ʻoi aku hoʻi i nā ʻōnaehana e hilinaʻi nui ana i ka mana DC, e like me nā panela solar a me nā ʻōnaehana mālama pila.

Ke koho ʻana i ka RCD kūpono
I ke koho ʻana i kahi RCD no kahi noi kikoʻī, he mea nui e noʻonoʻo i nā koi kikoʻī a me nā pilikia e pili ana i ke kau ʻana. He kūpono nā RCD ʻAno A no ka hapa nui o nā hale noho a me nā hale kalepa kahi e haʻahaʻa ai ka pilikia o ka hālāwai ʻana me nā au non-sinusoidal a i ʻole pulsating. Eia nō naʻe, i nā wahi kahi i ʻoi aku ka nui o ka pilikia o ka hālāwai ʻana me nā au DC maʻemaʻe, e like me nā hale hana ʻoihana a i ʻole nā ​​​​​​mea hana mana solar, ua ʻōlelo ʻia nā RCD ʻAno B e hāʻawi i ka pae kiʻekiʻe loa o ka palekana.

ʻO nā RCD ʻAno A a me ʻAno B he mau mea palekana koʻikoʻi i hoʻolālā ʻia e pale aku i ka haʻalulu uila a me nā pōʻino ahi i nā hoʻonohonoho uila. ʻOiai kūpono nā RCD ʻAno A no ka hapa nui o nā noi noho a me nā ʻoihana, hāʻawi nā RCD ʻAno B i kahi pae kiʻekiʻe o ka palekana a ua ʻōlelo ʻia no nā wahi kahi i ʻoi aku ai ka nui o ka pilikia o ka hālāwai ʻana me nā au DC maʻemaʻe.
Inā makemake ʻoe e ʻike hou aʻe e pili ana i kēia, e ʻoluʻolu e leka uila mai iā mākou.
