He aha ka fuse uila a pehea e hana ai?
Nā mea
Nui nā ʻāpana uila i kou home e palekana i ka fuse.
I kēlā me kēia manawa e ʻike ai ʻoe i ka piʻi ʻana o ka mana nui akā ʻike ʻoe ʻaʻole i wela kāu kumu hoʻonui i ka lepo, ʻo ka fuse, inā hoʻohana ʻia, ʻo ia ka mea e hōʻoia ai ʻo ia ka hihia.
He aha ka fuse a pehea e hana ai?
Ke ho'āʻo nei kā mākou alakaʻi e pane i kēia mau nīnau i kēia lā ke hōʻike nei mākou i nā mea āpau e pono ai ʻoe e ʻike e pili ana i hoʻokahi, me nā ʻano like ʻole a me ka ʻokoʻa o ka fuse mai kahi kaapuni kaapuni.
E iho kākou i ka ʻoihana.
He aha ka fuse?
ʻO ka fuse uila he mea liʻiliʻi me kahi ʻāpana lahilahi o ka conductor e pale ai i nā hale a me nā mea uila mai ka piʻi ʻana o ka mana. He mea pale uila kēia e ʻoki ai i ka mana i kahi mea kani a i ʻole ʻōnaehana uila ke ʻoi aku ke kahe o kēia manawa ma mua o ka waiwai i manaʻo ʻia.
ʻAʻole ʻo ka uila he mea e hoʻopōʻino ai iā mākou. E like me ka loaʻa ʻana o ke kanaka i ka nui o ka volta hiki ke hele i loko o ke kino me ka ʻole o nā mea make, ʻo kāu mau mea uila a me nā ʻōnaehana i loaʻa i kā lākou mau helu o kēia manawa a me ka voltage.
Ke ʻoi aku ka mana o ka mana i kēia mau palena, e hana ʻia kāu ʻōnaehana uila i mea make. Ma nā hale a me nā ʻoihana, ʻo ia ka mea e hoʻolilo i ka nui o ke kālā no ka hoʻoponopono ʻana a i ʻole ke hoʻololi ʻana i nā mea waiwai a me nā mea hana.
I kekahi manawa, ʻo ka piʻi ʻana o ia ʻano, inā ʻaʻohe pale, hiki ke hana i ke ahi a pilikia loa i ke kanaka. No ka pale ʻana i nā hopena ʻino o ka overcurrent, hoʻokomo ʻia kahi fuse.
He aha ka hana a ka fuse?
No ka pale ʻana i ka piʻi ʻana o ka mana, hoʻoheheʻe kahi kaula conductive lahilahi i loko o ka fuse a wāwahi i ke kaapuni. No laila, hoʻopau ʻia ke kahe o ka uila i nā ʻāpana ʻē aʻe o ke kaapuni a mālama ʻia kēia mau ʻāpana mai ke ahi. Hoʻohana ʻia ka fuse ma ke ʻano he mea hōʻeha no ka pale o ka overcurrent.
ʻO ka conductor lahilahi he uwea i loko a i ʻole mea i hana ʻia me ka zinc, keleawe, a i ʻole aluminika, a me nā metala ʻē aʻe.
Hoʻokomo ʻia ka fuse i loko o ke kaʻapuni i hiki i nā mea āpau ke holo i loko. I loko o ka fuse pono'ī, ua hoʻokomo ʻia nā uea ma waena o ʻelua mau ʻāpana a hoʻopili i nā hopena ma nā ʻaoʻao ʻelua.
Ma waho aʻe o ka puhi ʻana ma muli o ka hāʻawi ʻana i ka mana, puhi pū kekahi fuses i ka wā pōkole a i ʻole ka hewa o ka honua.
Loaʻa ka hewa ʻāina ke loaʻa kahi alakaʻi haole ma ke kaapuni e lilo i ʻāina ʻokoʻa.
Hiki ke hana ʻia kēia kaapuni pōkole e ka lima kanaka a i ʻole kekahi mea metala e pili ana me kahi uwea ola. ʻO kahi fuse uila i hoʻolālā ʻia no kēia mea e puhi a heheʻe paha.
He mea maʻalahi ka ʻike inā ua puhi ʻia kahi fuse. Hiki iā ʻoe ke nānā ʻike maka i nā ʻano alohilohi e ʻike inā ua haki, hoʻoheheʻe, a puhi ʻia paha ka uea.
Hiki iā ʻoe ke hoʻohana i ka multimeter e nānā i ka hoʻomau ʻana o ka fuse. ʻO kēia ke ʻano diagnostic pololei loa.
Nā hiʻohiʻona o nā fuse uila
Hele mai nā Fuses i nā manaʻo like ʻole a me nā helu like ʻole. ʻO ka helu fuse ka helu kiʻekiʻe loa o kēia manawa a i ʻole ka volta e hiki ke hele i kāna uea metala lahilahi ma mua o ka heheʻe.
He 10% ka haʻahaʻa o kēia helu ma mua o ka helu o ka hāmeʻa a ka fuse e pale ai, no laila ua lawa ka pale.
Hiki i ka fuse ke loaʻa nā mana haʻihaʻi ʻokoʻa a me nā manawa hana like ʻole ma muli o ke ʻano o ka fuse.
helu helu o kēia manawa
ʻO ke au i helu ʻia ʻo ia ke au kiʻekiʻe loa i helu ʻia ka fuse. ʻO ka nui iki o kēia helu e alakaʻi i ka pau ʻana o ka uea.
Eia nō naʻe, hoʻohana mau ʻia kēia helu me ka helu volta a me ka helu manawa huakaʻi, e hilinaʻi ana i ke kaapuni kahi i hoʻohana ʻia ai ka fuse.
pae uila
E like me ka helu o kēia manawa, ʻo ka helu volta o kahi fuse ʻo ia ka voltage kiʻekiʻe loa e hiki ai i ke kaula hao ke lawelawe. Eia naʻe, i ka wā e hoʻoholo ai i kēia waiwai, hoʻonohonoho maʻamau ia ma luna o ka volta hāʻawi mai ke kumu.
He mea koʻikoʻi kēia inā he nui nā mea hana i loko o ka ʻōnaehana uila e hoʻohana ana i ka helu helu like ʻole akā ʻokoʻa ka helu helu. Hoʻonohonoho pinepine ʻia ka volta helu i ka volta palekana kiʻekiʻe.
Ma muli o kēia, ʻaʻole hoʻohana ʻia nā ʻano ʻano uila uila i nā kaʻa haʻahaʻa haʻahaʻa a i ʻole nā ʻōnaehana e hāʻawi i ka pale o nā mea pono.
Ka manawa hāʻina
ʻO ka manawa fuse ka lohi ma mua o ka pau ʻana o ke kaula metala. ʻO kēia manawa pane e pili pono ana i ka helu o kēia manawa i mea e hāʻawi ai i ka pale kūpono loa.
No ka laʻana, koi ʻia nā fuse maʻamau i kahi kumu mana ʻelua i ko lākou helu e puhi i hoʻokahi kekona, ʻoiai ʻo nā fuse puhi wikiwiki me ka helu like a hiki ke puhi i ka mana i 0.1 kekona. Hoʻopau ka fuse i ka manawa ma hope o 10 mau kekona.
ʻO ke koho o lākou e pili ana i ka naʻau a me nā ʻano o ka mea pale.
Hoʻohana ʻia nā fuses wikiwiki i nā noi me nā ʻāpana i maʻalahi loa i nā piʻi liʻiliʻi o kēia manawa, ʻoiai e hoʻohana ʻia nā fuses lohi a hoʻopaneʻe paha i nā kaʻa kaʻa kahi e huki pinepine ai nā ʻāpana i ke au ma mua o nā kekona.
Ka mana haki
ʻO ka mana hoʻoheheʻe fuse ka helu i hoʻohana ʻia i nā mana haʻihaʻi kiʻekiʻe (HRC). Hāʻawi ka HRC fuses i ka holo ʻana o ka overcurrent no kekahi manawa me ka manaʻo e emi ana ia. Haʻihaʻi a hoʻoheheʻe lākou inā ʻaʻole hiki mai kēia ʻoki.
Ua kuhi pololei paha ʻoe he kikoʻī kēia i nā ʻano hoʻopaneʻe manawa a ʻo ka wahi haʻi wale nō ka ʻoi loa i ʻae ʻia i kēia manawa lohi pōkole.
Ke hiki ʻole ka manawa lohi i koho ʻia, akā ʻoi aku ka ikaika o ka tensile, puhi a heheʻe paha ka fuse. He ʻano pale pālua kēia. Ma kēia ʻano, hiki ke kapa ʻia nā fuse HRC i nā fuse hiki ke haki kiʻekiʻe (HBC).
Aia kekahi mau fuse HRC voli kiʻekiʻe i hoʻohana ʻia i nā kaʻa uila uila kiʻekiʻe a me nā fuse HRC haʻahaʻa haʻahaʻa i hoʻohana ʻia i nā ʻōnaehana hoʻoili uila haʻahaʻa. ʻOi aku ka nui o kēia mau fuses HRC haʻahaʻa ma mua o nā fuses maʻamau.
Hoʻolālā fuse
Ma keʻano laulā, hoʻoholo ka helu fuse i kona ikaika a me ka hoʻolālā. No ka laʻana, i loko o nā fuse mana kiʻekiʻe hiki ke loaʻa iā ʻoe kekahi mau kaula a i ʻole nā uea metala, aʻo kekahi mau fuse ʻē aʻe e hoʻohana i nā koʻokoʻo kila e kākoʻo i ke kaula mai ke kaua ʻana.
Hoʻohana kekahi i nā mea e hoʻomalu ai i ka māhele ʻana o ke metala, a e ʻike pū ʻoe i nā uwea lipine i hana ʻia e like me nā pūnāwai e wikiwiki ai i ke kaʻina hana.
Moolelo o ka Fuse
Hoʻomaka ka mōʻaukala o ka fuse i ka makahiki 1864. ʻO ia ka manawa i manaʻo ai ʻo Breguet e hoʻohana i kahi mea hoʻokele ma ka pūnaewele e pale i nā kikowaena telegarapa mai nā uila. A laila, no kēia kumu, ua hana ʻia nā uea conductive e hana like me ka fuse.
Eia naʻe, ʻaʻole i hiki i ka makahiki 1890 i hoʻopaʻa ʻia ʻo Thomas Edison i ka hoʻohana ʻana i kahi fuse i nā ʻōnaehana hoʻoili uila e pale aku i nā hale mai kēia mau piʻi nui o kēia manawa.
He aha nā ʻano fuse?
ʻO ka maʻamau, ʻelua ʻano o nā fuses. ʻO kēia nā AC fuses a me DC fuses. ʻAʻole paʻakikī ke hoʻomaopopo i ka ʻokoʻa ma waena o nā mea ʻelua.
Hana wale ʻo AC fuses me AC aʻo DC fuses e hana pū me DC. Eia naʻe, hoʻokahi ʻokoʻa koʻikoʻi ma waena o nā mea ʻelua e ʻike paha ʻoe he ʻoi aku ka nui o nā fuse DC ma mua o nā fuse AC.
I kēia manawa ua hoʻokaʻawale ʻia kēia mau ʻāpana ʻelua i nā fuses haʻahaʻa a me nā fuses kiʻekiʻe. Hoʻokaʻawale ʻia nā koho fuse kikoʻī i kēia mau pūʻulu ʻelua.
Nā fuse uila haʻahaʻa
ʻO nā fuses haʻahaʻa haʻahaʻa he mau fuse e hana ana ma kahi helu haʻahaʻa haʻahaʻa. Hiki ke mahele ia lakou i elima mau ano; nā pahu pahu pahu, nā pahu hoʻokuʻi, nā pahu hopena, nā pahu hoʻololi a me nā pahu huki.
- ʻO nā fuse uila hiki ke hoʻololi. Hoʻohana nui ʻia nā fuse hiki ke hoʻololi ʻia i nā ʻōnaehana hāʻawi mana ma nā hale a me nā keʻena. ʻO kēia nā fuse i uhi ʻia i ka porcelain me kahi lima e hana me ke kumu o ka fuse. Loaʻa iā lākou ʻelua mau ʻāpana lau no ka loaʻa ʻana a me ka hoʻokuʻu ʻana i ka uila ma ke kaapuni, e like me ka hoʻolālā fuse maʻamau.
Hoʻohana ʻia nā fuse demountable i ka home a me ke keʻena ʻoihana ma muli o ka maʻalahi o ka hoʻopili ʻana a me ka wehe ʻana iā lākou mai ke kumu.
- Nā pahu pahu pahu: ʻO kēia nā fuse me nā mea a pau i hoʻopaʻa ʻia i loko o kahi pahu, me nā pahu kaapuni wale nō i ʻike ʻia. Hiki mai nā pahu pahu pahu ma nā ʻano he nui a loaʻa nā ʻano hana like ʻole.
ʻO ka pahu pahu pahu D-type he ʻano ʻōmole a ʻike pinepine ʻia i nā mea hana liʻiliʻi. Hoʻokomo pinepine ʻia lākou i loko o kahi pahu seramika me nā welau metala e hoʻokele i ka uila.
ʻO nā fuse nā fuse HRC haʻahaʻa haʻahaʻa, ʻoiai hiki ke hoʻololi maʻalahi ʻia nā fuse blade, e like me nā fuse hiki ke hoʻohui hou ʻia, akā ua uhi ʻia i ka plastic. Hoʻohana mau ʻia nā fuse blade i nā kaʻa.
- ʻAʻole hoʻohana ka mea hoʻoheheʻe uila i kahi kaula hoʻoheheʻe lahilahi. Akā, hoʻokuʻu ʻo ia i kahi pine hoʻopili e wāwahi i ke kaapuni a lawelawe pū kekahi ma ke ʻano he ʻike maka waho e hoʻoholo ai inā ua puhi ʻia kahi fuse.
- Hoʻololi fuses: ʻO kēia nā fuses i hoʻohana ʻia i nā ʻōnaehana uila haʻahaʻa me nā hoʻololi waho e hiki ke hoʻohana ʻia e pani a wehe paha i ke ala o kēia manawa.
- Nā fuse hāʻule i lalo: Hoʻokuʻu nā fuse hāʻule i lalo i kahi kaula i hoʻoheheʻe ʻia mai lalo a loaʻa maʻamau i nā ʻōnaehana hoʻokuʻu uila haʻahaʻa.
Kiʻekiʻe voltage fuses
Hiki mai nā fuse volena kiʻekiʻe i nā ʻano like ʻole. Aia nā HRC wai kiʻekiʻe voluma fuses e hoʻohana i nā wai e kinai i ke arc.
Loaʻa iā mākou nā pahu pahu pahu e hoʻohana ana i ka waikawa boric e hoʻopau i ke kaʻina hana, a me nā pahu pahu pahu HRC e hana like me kā lākou mau mea uila haʻahaʻa.
Ma hea e hoʻohana ʻia ai nā fuse?
Hoʻohana pinepine ʻia nā fuse i nā ʻōnaehana AC liʻiliʻi a nui me nā mea hoʻololi. Hoʻohana ʻia nā fuses kiʻekiʻe me ka helu kiʻekiʻe o kēia manawa i nā mea hoʻololi ʻōnaehana mana e hana ana a hiki i 115,000 volts.
Hoʻohana ʻia nā fuse uila haʻahaʻa a me waena e pale i nā ʻōnaehana hoʻololi uila liʻiliʻi. ʻO kēia mau mea, ma waena o nā mea ʻē aʻe, nā ʻōnaehana i nā televise, nā pahu hau a me nā kamepiula.
Eia kekahi, inā hiki ke hoʻokomo i kahi fuse ma nā wahi āpau o ke kaapuni, ʻoi aku ka maikaʻi o ke kau ʻana ma ka hoʻomaka ʻana o ka ʻōnaehana. ʻO ia ke kumu e ʻike ai ʻoe i nā fuse i kau ʻia ma nā plug mea hana a i ʻole ma ke alo o kahi wahi pili mua o kahi transformer.
He aha nā poloka fuse?
ʻO nā pahu Fuse nā hub i loko o nā ʻōnaehana uila e mālama ai i nā fuse he nui e pale i nā ʻāpana like ʻole o kou home a i ʻole ke keʻena. Hoʻohana lākou ma ke ʻano maʻamau o ka pale ʻana i ka piʻi ʻana inā ʻaʻole i hoʻolako ʻia kekahi o kāu mau mea me kahi fuse kūloko.
E ʻike pinepine ʻoe i nā pahu fuse i kapa ʻia nā panela hoʻololi a i ʻole nā pahu hui, akā hana like lākou a pau. Loaʻa iā lākou ʻeono a ʻumikūmālua fuses i helu ʻia.
ʻOiai ua helu ʻia nā pahu fuse hale kahiko ma 60 amps, i kēia lā ke ʻike nei mākou i nā pahu fuse me ka helu helu he 200 amps. ʻO kēia ka huina o nā helu o nā fuse a pau i loko o ka pahu.
I kēia manawa, huikau pinepine nā pahu fuse me nā pahu kaapuni.
ʻO ka ʻokoʻa ma waena o nā fuse me nā mea hoʻopau kaapuni
Hana like nā mea hoʻopau kaapuni me nā fuse uila; pale lākou i nā mea hana hale mai ka piʻi ʻana o ka mana ma ke kāohi ʻana i ke kaapuni. Eia naʻe, ʻokoʻa ke ʻano o ka hana ʻana o nā mea ʻelua.
Ma kahi o ka hoʻoheheʻe ʻia ʻana a i ʻole ka mea i hoʻokuʻu ʻia, hana nā mea hoʻokaʻawale kaʻapuni me nā pilina kūloko a me nā hoʻololi waho. Hoʻopau maʻamau nā pilina kūloko i ke kaapuni, akā ua hoʻoneʻe ʻia i mua o ka overcurrent. ʻO ka mana o waho o ka mea hoʻokele kaapuni e kōkua i ka hoʻokomo ʻana i nā mea hoʻopili a me ka mea hoʻokele kaapuni i kahi kūlana pale.
Mai kēia hiki iā ʻoe ke ʻike i ka wā e hoʻololi mau ʻia ai nā fuse ke puhi lākou, hiki ke hoʻohana pinepine ʻia nā mea hoʻokele kaapuni. Pono ʻoe e hoʻonohonoho hou iā lākou. Hoʻokomo ʻia nā pahu hoʻokaʻawale kaapuni i ka nui o kēia mau hoʻololi ma mua o nā fuse.
I ka manawa e pani ai i ka fuse
Hiki i ka fuse ke ola a pau ke kau ʻia ma nā ʻōnaehana mana i manaʻo ʻia a ʻaʻohe piʻi o ka mana. Ua like kēia i ka wā ʻaʻole i hoʻokomo ʻia i loko o kahi ʻāina pulu a pulu paha kahi e hiki ai ke ʻino.
Eia naʻe, pono ʻoe e hoʻololi i nā fuse ma hope o 20-30 mau makahiki o ka hoʻohana ʻana. ʻO kēia ko lākou ola maʻamau.
