He aha nā mea o nā Fuse Voltage High?

ʻO ka mea mua, hiki iā mākou ke nānā i nā hiʻohiʻona o nā fuse voltage kiʻekiʻe.

E like me kā mākou ʻike, ʻo ka hana okiʻekiʻe voltage fusesʻo ia ka mālama ʻana i ke kaapuni.ʻO ia hoʻi, ke ʻoi aku ka nui o ke au o ke kaapuni i kahi waiwai i ʻōlelo ʻia, ʻo ka heheʻe i loko o ka fuse e hana i kahi ʻano wela e wāwahi ai i ke kaapuni.No laila, no ke kiʻekiʻe voltage fusing mea, pono e loaʻa ka haʻahaʻa heheʻe wahi, maʻalahi ke kinai ʻana i nā ʻano arc.ʻO ka maʻamau me ke keleawe, ke kālā, ka zinc, ke alakaʻi, ke kēpau kēpau a me nā mea ʻē aʻe.No ka mea ʻokoʻa nā mea hoʻoheheʻe o kēia mau mea, pono nā mea ʻokoʻa no nā au like ʻole.ʻO ko lākou mau wela hoʻoheheʻe e pili ana i 1080 ℃, 960 ℃, 420 ℃, 327 ℃ a me 200 ℃.

ʻO nā kuhikuhi no ka hoʻohana ʻana i kēia mau mea like ʻole:
1. He haʻahaʻa loa ka helu heheʻe o ka zinc, ke kēpau, ke kēpau a me nā metala ʻē aʻe, akā ʻoi aku ka nui o ka resistivity.No laila, ʻoi aku ka nui o ka hoʻohana ʻana i ka fuse cross-sectional area, ʻo ka mahu metala i hana ʻia i ka wā ʻaʻole kūpono ka fusing e hoʻopau i ke arc.Hoʻohana nui ʻia i ke kaapuni ma lalo o 1kV.
2. He kiʻekiʻe nā helu heheʻe o ke keleawe a me ke kālā, akā liʻiliʻi ka resistivity a me ka conductivity uila a me ka wela.No laila, liʻiliʻi ka hoʻohana ʻana o ka fuse cross-sectional area, ʻo ka mahu metala i hana ʻia i ka wā e hoʻohui ʻia ai ka liʻiliʻi, maʻalahi ke kinai ʻana i ke arc.Hiki ke hoʻohana ʻia i ka volta kiʻekiʻe, kaapuni o kēia manawa kiʻekiʻe.Eia naʻe, inā nui loa ke au, ʻoi aku ka kiʻekiʻe o ka mahana lōʻihi, maʻalahi e hōʻino i nā mea ʻē aʻe o ka fuse.I mea e wikiwiki ai ka hoʻoheheʻe ʻana i ka fuse, pono ia e kahe i kahi ʻoi aku ka nui, i ʻole e hoʻolōʻihi i ka manawa fuse, ʻaʻole maikaʻi i nā mea pale.I mea e hoʻopau ai i kēia hemahema, hoʻopili pinepine ʻia kahi pahu a i ʻole ke alakaʻi pellet ma ke keleawe a i ʻole ke kala hoʻoheheʻe e hōʻemi i ka wela hoʻoheheʻe a hoʻomaikaʻi i ka hana pale o ka heheʻe.
