JCRB2-100 Type B RCDs

Hāʻawi ʻo JCRB2-100 Type B RCD i ka pale ʻana i ke koena o nā ʻāhewa hewa / leakale honua i nā noi lako AC me nā ʻano nalu kikoʻī.

Hoʻohana ʻia nā RCD ʻano B kahi e hiki mai ai nā au koena DC maʻemaʻe a/a i ʻole ka pulsating, aia nā ʻano nalu non-sinusoidal a i ʻole nā alapine i ʻoi aku ma mua o 50Hz;no ka laʻana, Ka Uku Kaʻa Uila, kekahi mau mea hana 1-phase, micro generation a i ʻole SSEG (Small Scale Electricity Generators) e like me nā panela lā a me nā mea hana makani.

ʻO nā ʻano B RCDs (Koe o kēia manawa) he ʻano mea hana i hoʻohana ʻia no ka palekana uila.Hoʻolālā ʻia lākou e hāʻawi i ka pale ʻana i nā hewa ʻelua AC a me DC, e kūpono ana iā lākou no ka nui o nā noi, me nā mea e pili ana i nā ukana koʻikoʻi DC e like me nā kaʻa uila, nā ʻōnaehana ikehu hou, a me nā mīkini ʻenehana.Pono nā ʻano B RCDs no ka hāʻawi ʻana i ka pale piha i nā hoʻonohonoho uila hou.

Hāʻawi nā ʻano B RCD i kahi pae palekana ma mua o ka mea hiki i nā RCD maʻamau ke hāʻawi.Hoʻolālā ʻia nā RCD Type A no ka huakaʻi inā loaʻa kahi hewa AC, ʻoiai ʻo Type B RCDs hiki ke ʻike pū i ke koena o ka DC, i kūpono ia no ka ulu ʻana i nā noi uila.He mea koʻikoʻi kēia i ka ulu ʻana o ka noi no nā ʻōnaehana ikehu hou a me nā kaʻa uila, e hana ana i nā luʻi hou a me nā koi no ka palekana uila.

ʻO kekahi o nā pōmaikaʻi nui o Type B RCDs ʻo ko lākou hiki ke hāʻawi i ka pale i ke alo o nā ukana sensitive DC.No ka laʻana, hilinaʻi nā kaʻa uila i ke au pololei no ka hoʻoulu ʻana, no laila pono ke kau ʻia nā pae kūpono o ka pale e hōʻoia i ka palekana o ke kaʻa a me ka hoʻouka ʻana.Pēlā nō, hana pinepine nā ʻōnaehana ikehu hou (e like me nā panela lā) ma ka mana DC, e hana ana i ka Type B RCDs i mea koʻikoʻi i kēia mau hoʻonohonoho.

He aha ka ʻano B RCD?

ʻAʻole pono e huikau nā ʻano B RCD me nā ʻano B MCB a i ʻole RCBO e hōʻike ʻia ana ma nā hulina pūnaewele he nui.

He ʻokoʻa loa nā ʻano B RCD, akā naʻe, ua hoʻohana ʻia ka leka like i hiki ke alakaʻi hewa.Aia ka ʻAno B ʻo ia ka ʻano wela i loko o kahi MCB/RCBO a me Type B e wehewehe ana i nā ʻano magnetic i kahi RCCB/RCD.ʻO ia ka mea e ʻike ai ʻoe i nā huahana e like me RCBO me ʻelua mau hiʻohiʻona, ʻo ia ka mea magnetic o ka RCBO a me ka mea wela (hiki ke lilo i Type AC a i ʻole A magnetic a me kahi Type B a C thermal RCBO).

Pehea e hana ai nā ʻano B RCD?

Hoʻolālā pinepine ʻia nā ʻano B RCD me ʻelua ʻōnaehana ʻike i kēia manawa.Hoʻohana ka mea mua i ka ʻenehana 'fluxgate' e hiki ai i ka RCD ke ʻike i ka manawa DC maʻemaʻe.Hoʻohana ka lua i kahi ʻenehana e like me Type AC a me Type A RCDs, ʻo ia ke kūʻokoʻa voltage.
