Pili ka fuse palena o kēia manawa i loko o ka AC 50Hz, nā voltage helu o 3.6KV, 7.2KV, 12KV, 24KV, 40.5KV, nā au i helu ʻia o 0.5 a me 2, 3, 5, 7.5, 10A pūnaewele, a pili i ka pale ka nui a me ka pōkole kaapuni hewa o waho 35KV voltage transformers a me ka mana laina.Hiki ke hoʻohana pū ʻia me nā mea hoʻololi ʻē aʻe, e like me nā hoʻololi ukana a me nā mea hoʻopili maoli, ma ke ʻano he mea pale no ka pōkole pōkole a me ka overload o nā transformers mana a me nā mea hoʻihoʻi ʻē aʻe, a he huahana kākoʻo pono hoʻi no nā kiʻi hoʻololi kiʻekiʻe-voltage, apo. nā kiʻi pūnaewele, a me nā substation i hana mua ʻia.
Loaʻa i ka fuse ka palena o kēia manawa a me ka wikiwiki.Hōʻike pinepine ʻia ka haʻahaʻa haʻahaʻa o ka hapa hawewe.Ke hemo ke kino uwapo, e hoʻoneʻe ʻia ke au pōkole pōkole a pau i ka fuse palena palena kiʻekiʻe.ʻO ke au o ke kaapuni pōkole o loko o ka fuse e mahuka, e wāwahi, e hoʻohua i ka ʻawa ma waena o nā āpau a hoʻopau i ke arc i ka wā e hiki mai ana a i ka wā e piʻi aʻe ai, e kaupalena ʻia a ʻoki ikaika i ke au o ke kaapuni pōkole (t ~ 2ms), i hiki ʻole i ke au. hiki i ka waiwai kiʻekiʻe i manaʻo ʻia o ke au pōkole pōkole.Ke piʻi ka ʻauwaʻi pōkole i Ip, e hui ka fuse a ʻoki i ke au.ʻO ka Ip o kēia manawa i ʻoki ʻia ma kahi o 15% wale nō o ka waiwai kiʻekiʻe o ka manawa i manaʻo ʻia, e hōʻemi nui ana i ka hopena o ka hewa o kēia manawa i ka ikaika electrodynamic a me ka hopena wela o ka hana mana a me nā mea hoʻololi.Hiki ke kaupalena ʻia ka puʻupuʻu arc i hana ʻia e ka fuse palena palena ʻole, hiki ke hui pū me ke kūpaʻa alahaka e hoʻoponopono i ka pilikia o ka lawa ʻole o ka fuse palena kiʻekiʻe. mea hana.
Hoʻokumu ʻia ka fuse me kahi paipu hoʻoheheʻe, kahi porcelain bushing (silicone rubber insulation sheath), kahi flange hoʻopaʻa, kahi post insulator transverse a me kahi pahu.E hoʻopaʻa i nā pāpale hope a me nā paipu hoʻoheheʻe ma nā ʻaoʻao ʻelua o ka porcelain bushing ma ke kaomi ʻana, a laila hoʻopaʻa i ka porcelain bushing ma ke koʻokoʻo post insulator me kahi flange paʻa.
Hoʻohana ka paipu hoʻoheheʻe i ka mālama ʻana me ka silicon oxide kiʻekiʻe e like me ke ʻano hoʻopau arc, a hoʻohana ʻia ka uea metala me ke anawaena liʻiliʻi e like me ka fuse.Ke hele ke au o ke au a i ʻole ka ʻaapuni pōkole i loko o ka paipu hehee, e hehee koke ka fuse.Loaʻa ke arc ma nā ʻāpana haiki like.ʻO ka mahu metala i loko o ke arc e komo i loko o ke one quartz, ua hoʻokaʻawale ikaika ʻia, a hoʻopau koke i ke arc.No laila, ʻoi aku ka maikaʻi o ka fuse a me ka hiki ke haki nui.

1. Kiʻekiʻe haʻihaʻi hiki.ʻO ka mea maʻamau, ʻo 50kA ka helu ʻana i ka wā pōkole (ka waiwai i manaʻo ʻia) o nā fuse hoʻopau i kēia manawa he 50kA, a hiki i ka 63kA ka mana o nā huahana i lawe ʻia mai.
2. Hiki ke kaupalena i kēia manawa, nā fuses hoʻemi o ka mana kiʻekiʻe o kēia manawa, e like me nā fuse 100A, ʻo ke kumu kūʻai kiʻekiʻe o kēia manawa ma kahi o 18kA inā ʻo 50kA ka waiwai kūpono o ke au pōkole i manaʻo ʻia, ʻoiai no kekahi 100A fuse i lawe ʻia mai, i ka wā i manaʻo ʻia he 63kA ka waiwai kūpono o kēia manawa, ʻo 18kA wale nō ka waiwai kiʻekiʻe o kēia manawa.
3. Loaʻa ka palena haʻahaʻa haʻahaʻa.No nā fuse palena o kēia manawa no ka pale ʻana i ka mea hoʻololi, ʻo ka haʻahaʻa haʻahaʻa o kēia manawa he 3 a 5 mau manawa o ka manawa helu o ka fuse.I ke koho ʻana, pono e hōʻoia ʻia ʻaʻole ʻoi aku ka liʻiliʻi o ka fusing au ma mua o ka liʻiliʻi liʻiliʻi pōkole o ke kaapuni pale.
