1P+N, RCBO, B, C curve, ETM7RF, Koe Wehe ʻia o kēia manawa me ka pale ʻoi aku o kēia manawa, hoʻopili
Huahana Huahana
Hoʻopili ʻia ka ETM7RF series RCBO i ka hāʻawi haʻahaʻa haʻahaʻa haʻahaʻa i ka ʻoihana, hale kīwila e like me ka home a me ka hale, ka ikehu, ke kamaʻilio, ka ʻōnaehana, ka ʻōnaehana hoʻomālamalama kukui a i ʻole ka hāʻawi ʻana i nā kaʻa a me nā kula ʻē aʻe.Hāʻawi lākou i ka pale leakage, pale pōkole pōkole, pale overload, a me ka pale kaʻawale, hiki ke pale i ke kanaka mai ka ʻeha i hoʻokumu ʻia e ka leakage o kēia manawa, ma ka mea nui ʻoiai hiki iā lākou ke pale aku i ke kaapuni a me nā mea hana mai ka ulia lua i hana ʻia e ka overload a me ka pōkole. kaapuni.
Ua hoʻokō ʻo ETM7RF series RCBO i ka IEC 61009-1standard.
ʻO ka haʻihaʻi ʻana o ETM7RF ʻo 10KA, a i ʻole 6KA
ʻO ke ʻano kuʻi ʻana o ke kaapuni pōkole ʻo B, C curve.
ʻO ka helu o kēia manawa he 6A, 10A, 16A, 20A, 25A, 32A, 40A.Hoʻohana maʻamau ʻia ka manawa i helu ʻia i nā wahi like ʻole me ka laʻana hoʻokahi pole 10 a 16 ampere e hoʻohana mau ʻia no ke kukui, 20 a 33 ampere e hoʻohana mau ʻia no ka lumi kuke a me ka lumi ʻauʻau, hoʻohana ʻia no ka ea a me nā mea hana ʻē aʻe.
ʻO ka sensitivity o ke koena o kēia manawa, a i ʻole ka leakage honua he 10mA, 30mA, 100mA, aʻo 10mA a me 30mA ke hoʻohana nui ʻia i ke kaʻapuni o ka lumi ʻauʻau a me ka lumi kuke e pale ai i ke kanaka mai ka haʻalulu uila.
ʻO ke ʻano o ka hele ʻana o ke koena o kēia manawa ʻo AC a i ʻole papa A.Hoʻopaʻa ʻia ka AC class Tripping no ka sinusoidal, nā ʻano ʻē aʻe, inā e hoʻopili koke ʻia a hoʻonui lohi paha.Hoʻopaʻa ʻia kahi papa Tripping no ka sinusoidal, nā ʻano ʻē aʻe o ke koena a me ka pulsed DC koena au, inā e hoʻohana koke ʻia a hoʻonui lohi paha.
Volta i helu ʻia: 230V/ 240V (Pāhā a me Neutral)
Aia kahi hōʻailona kūlana i hoʻolako ʻia ma nā huahana, ʻulaʻula, pio ka ʻōmaʻomaʻo.
ʻO nā pahu RCBO he IP20 ka pale i hoʻolālā ʻia no ka paʻi lima a me ka lima paʻa palekana e mālama i ka palekana i ka wā e hoʻokomo ai.
Hiki i ka ETM7RF RCBO ke hana me ka hilinaʻi i loko o ke kaiapuni koʻikoʻi, i ka mahana ambient mai -25°C a i 55°C.
Hiki i ke ola uila ke piʻi i ka 8000 hana a me ke ola mechanical a hiki i ka 20000 hana, ʻoiai ke koi IEC he 4000 mau hana a me 10000 mau hana.
ʻO ke ʻano o ka hoʻokomo ʻia ʻana o nā terminals he plug in type ma ka ʻaoʻao hoʻokomo, a me ke ʻano uea ma ka ʻaoʻao puka.
He aha ka RCBO?
Kū ʻo RCBO no Residual Current Breaker me ka Over-Current pale.Hoʻohui ka RCBO i ka hana o kahi MCB a me RCD/RCCB.Ke loaʻa kahi leaka i kēia manawa, holo ka RCBO i ke kaapuni holoʻokoʻa.No laila, hiki i nā ʻāpana hoʻoheheʻe magnetic/thermal circuit breaker ke hoʻoheheʻe i ka mea uila ke hoʻonui ʻia ke kaapuni.
1. Ke koena o kēia manawa, a i ʻole Ka Leaka ʻĀina - E hana ʻia ke ʻoki ʻia i ka pōʻai ma o ka uwea uila maikaʻi ʻole a i ʻole nā ulia DIY e like me ka wili ʻana ma ke kaula i ka wā e kau ai i ka makau kiʻi a i ʻole ke ʻoki ʻana i ke kaula me ka mower mauu.I kēia manawa, pono e hele ka uila i kahi e koho ai i ke ala maʻalahi e hele ai ma o ka mīkini ʻauʻau a i ʻole ka wili i ke kanaka e hoʻoulu ai i ka uila.
2. ʻElua mau ʻano o Over-Current:
a.Kaumaha - Hana ʻia ke hoʻohana ʻia nā mea hana he nui ma ke kaapuni, e huki ana i ka nui o ka mana ma mua o ka hiki o ke kaula.
b.Kaapuni Pokole - Loaʻa ka pilina pololei ma waena o nā mea hoʻokele ola a kūʻole.Me ka ʻole o ke kūʻē ʻana i hāʻawi ʻia e ka pono kaapuni maʻamau, holo ka mana uila a puni ke kaapuni i loko o kahi loop a hoʻonui i ka amperage i nā kaukani manawa he nui i loko o nā milliseconds wale nō a ʻoi aku ka pōʻino ma mua o ka Overload.
ʻOiai ua hoʻolālā ʻia kahi RCCB no ka pale ʻana i ka leaka honua a pale wale ka MCB i ka over-current, pale ka RCBO i nā ʻano hewa ʻelua.
Me kā mākou hoʻokele maikaʻi, nā mana ʻenehana ikaika a me nā ʻenehana hoʻokele koʻikoʻi koʻikoʻi, hoʻomau mākou i ka hāʻawi ʻana i kā mākou mea kūʻai aku me ka maikaʻi hilinaʻi, nā kumukūʻai kūpono a me nā mea hoʻolako maikaʻi loa.Manaʻo mākou e lilo i hoʻokahi o kāu mau hoa hilinaʻi nui a hāʻawi iā ʻoe i nā hana kiʻekiʻe o ke koena o kēia manawa kaʻapuni kaʻapuni, mahalo mākou i ka manawa kūpono e hana ʻoihana me ʻoe a makemake mākou e loaʻa ka hanohano e hoʻopili i nā kikoʻī hou aku o kā mākou huahana.Kiʻekiʻe hana Kina koena o keia manawa kaapuni breaker kuapo, makou e kaumaha ana i ka laulā huahelu o keia kahua.Eia kekahi, loaʻa nā kauoha maʻamau.ʻO ka mea hou aku, e hauʻoli ʻoe i kā mākou lawelawe kiʻekiʻe.Ma kahi huaʻōlelo, ua hōʻoia ʻia kou ʻoluʻolu.Welina mai e kipa i kā mākou hui!No ka ʻike hou aku, e kipa i kā mākou pūnaewele.Inā he nīnau hou kāu, e ʻoluʻolu e kelepona mai iā mākou.
I kēia manawa, ʻo kēia ʻano o ka mea pale leakage ka mea i hoʻohana nui ʻia.Hoʻohana maʻamau ʻia nā hoʻololi pale leakage ma ka mākeke i nā ʻāpana aʻe e like me kā lākou hana:
(1) Loaʻa iā ia ka hana o ka pale leakage a me ka mana-off, a pono e hoʻohana ʻia me nā mea pale e like me fuses, thermal relays, a me nā relay overcurrent.
(2) I ka manawa like, loaʻa iā ia ka hana o ka pale overload.
(3) I ka manawa like, loaʻa iā ia ka overload a me nā hana pale pōkole pōkole.
(4) I ka manawa like, loaʻa iā ia ka hana o ka pale kaapuni pōkole.
(5) I ka manawa like, loaʻa iā ia nā hana o ka pōkole pōkole, overload, leakage, overvoltage a me ka undervoltage.ʻO ke kumu pale leakage e pili ana i ke kumu mana i hiki ke ʻike a hoʻoponopono i ka leakage o kēia manawa a ʻoki i ke kaapuni.ʻO ka manawa i helu ʻia ma lalo o 20A, ʻo ka leakage o kēia manawa he 6-30mA, a ʻoi aku ka kiʻekiʻe o ka naʻau.
