Hoʻohana nui ʻia nā mea hoʻopili AC haʻahaʻa haʻahaʻa e hoʻohuli a hoʻopau i ka mana o nā lako uila, hiki ke hoʻomalu i nā lako mana mai kahi lōʻihi, a pale i ka hōʻeha pilikino i ka wā e hoʻohuli ai a hoʻopau i ka lako mana o nā lako. He mea koʻikoʻi ke koho ʻana o ka contactor AC no ka hana maʻamau o nā lako mana a me nā laina mana.
1. Hoʻolālā a me nā palena o AC contactor
Ma ka hoʻohana maʻamau, koi ʻia ka mea hoʻopili AC e loaʻa i kahi ʻano paʻa, maʻalahi e hoʻohana, kahi mea hoʻoheheʻe magnetic maikaʻi no ka neʻe ʻana a me nā pilina paʻa, ka hopena hoʻopau arc maikaʻi, zero flashover, a me ka piʻi liʻiliʻi o ka wela. Wahi a ke kaʻina hoʻopau arc, ua hoʻokaʻawale ʻia i ke ʻano ea a me ke ʻano vacuum, a e like me ke ʻano hana, ua māhele ʻia i ke ʻano electromagnetic, ʻano pneumatic a me ke ʻano pneumatic electromagnetic.
Hoʻokaʻawale ʻia nā ʻāpana uila helu o ka contactor i ka volta kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, a ʻo ka haʻahaʻa haʻahaʻa he 380V, 500V, 660V, 1140V, etc.
Hoʻokaʻawale ʻia ke au uila i ke au a me ke au pololei e like me ke ʻano. Loaʻa nā ʻāpana o kēia manawa i helu ʻia ka hana o kēia manawa, ʻae ʻia ka hoʻomehana ʻana i kēia manawa, ka hana ʻana i kēia manawa a me ka haki ʻana i kēia manawa, ʻae ʻia ka hoʻomehana ʻana o nā mea hoʻopili kōkua a me ka manawa pōkole kū i kēia manawa o ka contactor, a me nā mea ʻē aʻe. nā au hana e pili ana i ke au mehana i ʻaelike ʻia. No ka laʻana, no CJ20-63, ua hoʻokaʻawale ʻia ke ʻano o ka hana ʻana o ka pilina nui i 63A a me 40A. 63 i loko o ke kŘkohu kŘkohu e pili ana i ka aelike mehana au, e pili ana i ka insulation hale o ka contactor ka pūpū, a me ka helu hana o keia manawa pili i ka i waeia haawe o keia manawa, pili i ka voltage pae.
Hoʻokaʻawale ʻia nā coils contactor AC i 36, 127, 220, 380V a pēlā aku e like me ka volta. Ua maheleia ka helu o na pou o ka contactor i 2, 3, 4, 5 pole a pela aku. Nui nā hui o nā hui kōkua e like me ka wehe maʻamau a pani ʻia, a koho ʻia e like me nā pono mana.
ʻO nā ʻāpana ʻē aʻe e pili ana i ka pilina, nā manawa haʻihaʻi, ke ola mechanical, ke ola uila, ke alapine hana hiki ke ʻae ʻia, ke anawaena wili i ʻae ʻia, nā ana waho a me nā ana hoʻonohonoho, etc.Classification o contactors
Nā ʻano mea hoʻopili maʻamau
E hoʻohana i ke code waeʻano no ka hoʻouka maʻamau
AC-1 non-inductive a iʻole micro-inductive haʻawe, resistive load resistance furnace, heater, etc.
Ke hoʻomaka a me ka haki ʻana o AC-2 ʻeha induction motor Cranes, compressors, hoists, etc.
AC-3 cage induction motor e hoʻomaka ana, e wāwahi ana i nā mea pā, nā pamu, a pēlā aku.
AC-4 cage induction motor e hoʻomaka ana, reverse braking a i ʻole kokoke i ka pā kaʻa, pamu, mīkini mea hana, etc.
ʻO ke kukui hoʻokuʻu AC-5a ma luna o nā kukui hoʻokuʻu kinoea kiʻekiʻe e like me nā kukui mercury, nā kukui halogen, etc.
Nā kukui ʻāʻī no nā kukui kukui AC-5b
AC-6a transformer on-off mikini wiliwili
ʻO ka capacitor on-off o ka capacitor AC-6b
AC-7a Nā mea hana hale a me nā umu microwave haʻahaʻa haʻahaʻa haʻahaʻa like, nā mea maloʻo lima, etc.
ʻO ka pahu hau kaʻa kaʻa home AC-7b, ka mīkini holoi a me nā mana ʻē aʻe i ka a i ʻole
ʻO AC-8a ka mea hoʻopololei kaʻa me ka hermetic refrigeration compressor me ka manual reset overload release
ʻO AC-8b mea hoʻopololei me ka hermetic refrigeration compressor me ka manual reset overload release
