E wehewehe pakahi ia keia mau mea a pau no kou ike piha.
DC fuse
ʻO ka ʻōlelo maʻalahi, ʻo nā fuse DC kahi ʻano o ka fuse uila i hoʻohana ʻia i nā kaapuni DC. ʻOiai ʻo kēia ke kumu nui e hoʻokaʻawale iā lākou mai nā fuses o kēia manawa (AC), aia kekahi hiʻohiʻona e pono e haʻi ʻia.
ʻOi aku ka nui o nā fuse DC ma mua o nā fuse AC e pale i ka hoʻopaʻa ʻana.
Inā ʻoi aku ka nui o ka fuse DC a i ʻole pōkole a heheʻe ke kaula hao, e wehe ʻia ke kaapuni.
Eia nō naʻe, ma muli o ke ʻano o ka DC a me ka uila i ke kaapuni mai ke kumu DC, ʻo ka liʻiliʻi liʻiliʻi ma waena o nā ʻaoʻao ʻelua o ke kaula i hoʻohui ʻia e hoʻokumu i ka hiki ke loaʻa kahi huna huna mau.
Hoʻopau kēia i ke kumu o ka fuse no ka mea e kahe mau ana ka mana ma ke kaapuni. No ka pale ʻana i ka hoʻāla ʻana, ua hoʻonui ʻia ka fuse DC, kahi e hoʻonui ai i ka mamao ma waena o nā ʻaoʻao hehee ʻelua o ke kaula.
Huina AC
Ma ka ʻaoʻao ʻē aʻe, ʻo nā fuses AC nā fuse uila e hana pū me nā kaapuni AC. ʻAʻole pono lākou e hana hou ʻia e hoʻomaikaʻi i ka hoʻolako ʻana i ka mana alapine.
Hoʻohana ʻia ke ʻano ʻokoʻa ma kahi voli e loli ana mai ka pae kiʻekiʻe a i ka pae haʻahaʻa (0 V), maʻamau 50 a 60 mau manawa i kēlā me kēia minuke. 'O ia ho'i, i ka wā e hehe'e ai ke kaula, hiki ke pio ke pio ke ho'emi 'ia kēia volta i ka 'ole.
ʻAʻole pono e ʻoi aku ka nui o ka fuse uila, no ka mea, ua pau ka hāʻawi ʻana o ke au i ka hāʻawi ʻana iā ia iho.
I kēia manawa, ʻo AC fuses a me DC fuses nā ʻāpana nui ʻelua o nā fuses uila. A laila hoʻokaʻawale mākou iā lākou i ʻelua mau ʻāpana; nā fuses uila uila haʻahaʻa a me nā fuse uila uila kiʻekiʻe.
Fuse uila uila haʻahaʻa
Ke hana nei kēia ʻano fuse uila ma kahi kaapuni me ka volta helu i emi iho a i ʻole like me 1,500 V. Hoʻohana mau ʻia kēia mau fuse uila i nā kaʻa uila uila haʻahaʻa a hele mai i nā ʻano like ʻole, nā hoʻolālā a me nā nui.
ʻOi aku ka liʻiliʻi ma mua o kā lākou mau mea uila kiʻekiʻe a maʻalahi ke hoʻololi.
Fuse uila uila kiʻekiʻe
ʻO nā fuses uila kiʻekiʻe nā fuse uila i hoʻohana ʻia me nā helu uila ma luna o 1,500V a hiki i 115,000V.
Hoʻohana ʻia lākou i nā ʻōnaehana mana nui a me nā kaapuni, hele mai i nā ʻokoʻa like ʻole a hoʻohana i nā hana koʻikoʻi e hoʻopau i kahi arc uila, ʻoi aku hoʻi i ka wā e pili ana i kahi kaapuni DC.
A laila, hoʻokaʻawale ʻia nā fuse uila kiʻekiʻe a haʻahaʻa i nā ʻano like ʻole, i hoʻoholo nui ʻia e kā lākou hoʻolālā.
pahu pahu pahu
ʻO ka pahu pahu pahu kahi ʻano o ka fuse uila kahi i hoʻopaʻa ʻia ai ke kaula a me nā mea hoʻopio arc i loko o kahi pahu aniani a i ʻole aniani.
ʻO ia ka mea maʻamau nā fuse uila cylindrical me nā pāpale metala (i kapa ʻia ʻo lugs) a i ʻole nā lau metala ma nā ʻaoʻao ʻelua e lilo i wahi pili no ka pili ʻana i ke kaapuni. Hoʻohui ʻia kahi fuse a i ʻole i loko o loko i kēia mau kihi ʻelua o ka pahu pahu pahu e hoʻopau i ke kaapuni.
ʻIke ʻoe i nā pahu pahu pahu me nā noi i nā kaʻa kaʻa e like me nā pahu hau, nā pā wai a me nā ea, a me nā mea ʻē aʻe.
ʻOiai ʻoi aku ka nui o lākou i nā ʻōnaehana uila haʻahaʻa i helu ʻia a hiki i 600A a me 600V, ʻike paha ʻoe i kā lākou hoʻohana ʻana i nā kaiapuni kiʻekiʻe. ʻOiai ʻo kēia a me ka hoʻohui ʻana o kekahi mau mea e kaupalena ʻia ai ka sparking, e mau ana kā lākou hoʻolālā holoʻokoʻa.
Hiki ke hoʻokaʻawale ʻia nā pahu pahu pahu i ʻelua mau ʻāpana ʻē aʻe; Nā fuse uila ʻano D a me nā fuse ʻano Link.
ʻAno D pahu pahu pahu
ʻO nā fuse D-type nā ʻano nui o nā pahu pahu pahu i loaʻa kahi kumu, kahi apo adapter, kahi pahu pahu a me kahi pāpale fuse.
Hoʻopili ʻia ke kumu fuse i ka uhi fuse a ua hoʻopili ʻia kahi kaula metala a i ʻole uea lele i kēia kumu fuse e hoʻopau i ke kaapuni. Hoʻopau koke nā fuses Type D i ka lako mana ke ʻoi aku ka nui o ke au o ke kaapuni.
ʻAno loulou/HRC Cartridge Fuse
Hoʻohana ka loulou a i ʻole ka hiki haʻihaʻi kiʻekiʻe (HRC) nā loulou fuse ʻelua no ka mīkini hoʻopaneʻe manawa i ka pale ʻana i ka overcurrent a pōkole paha. Ua kapa ʻia kēia ʻano fuse fuse kiʻekiʻe breaking capacity (HBC).
Hoʻonohonoho like ʻia nā loulou fusible ʻelua a i ʻole nā pa, ʻo kekahi me ke kūʻē haʻahaʻa a ʻo kekahi me ke kūpaʻa kiʻekiʻe.
Ke hoʻohana ʻia ke au i ke kaapuni, hoʻoheheʻe koke ka loulou fusible pale haʻahaʻa, ʻoiai ʻo ka fuse kūʻē kiʻekiʻe e paʻa i ka mana keu no kahi manawa pōkole. A laila e puhi ʻia inā ʻaʻole e hoʻemi ʻia ka mana i kahi pae ʻae ʻia i loko o kēia manawa pōkole.
Inā ho'omaka koke ke au ha'i helu i ka wā e loa'a ai ka overcurrent ma ke kaapuni, e hehee koke ka loulou fuse kū'ē ki'eki'e.
Hoʻohana pū kēia mau ʻano o nā fuse uila HRC i nā mea e like me ka pauka quartz a i ʻole nā wai hoʻoheheʻe ʻole e kaupalena a hoʻopau paha i ke arc uila. I kēia hihia ua kapa ʻia lākou he HRC wai fuses a maʻamau i nā ʻano volta kiʻekiʻe.
Aia kekahi ʻano ʻē aʻe o nā fuse uila HRC, e like me nā fuse bolt-on, nona nā pahu hoʻonui me nā lua, a me nā fuses ʻili, i hoʻohana nui ʻia i loko o ke kaʻa kaʻa a loaʻa i nā pahu pahi ma kahi o nā pāpale.
Loaʻa maʻamau ka pahu palaki ʻo Blade fuse a maʻalahi ke wehe ʻia mai ke kaʻapuni inā loaʻa kahi hana ʻino.
Fuse hiki ke pani
Ua kapa ʻia nā fuses hiki ke hoʻololi ʻia he fuses uila semi-pani. ʻElua mau ʻāpana i hana ʻia me ka porcelain; he mea hoʻopaʻa fuse me kahi lima a me kahi kumu fuse i hoʻokomo ʻia ai kēia mea hoʻopaʻa fuse.
ʻO ka hoʻolālā ʻana o nā fuse hiki ke wehe, hoʻohana mau ʻia i nā hale noho a me nā wahi haʻahaʻa haʻahaʻa o kēia manawa, e maʻalahi lākou e paʻa me ka ʻole o ka haʻalulu uila. Loaʻa i ka mea hoʻopaʻa fuse nā pauku maka a me kahi loulou fuse.
Ke heheʻe ka loulou fusible, hiki ke wehe maʻalahi ka paʻa fuse e pani ai. Hiki ke hoʻololi maʻalahi ka mea paʻa holoʻokoʻa me ka pilikia ʻole.
Fuse kuʻi
Hoʻohana ka fuse i kahi ʻōnaehana mechanical e pale aku i ka overcurrent a i ʻole ka pōkole pōkole, a e hōʻike i ka puhi ʻana o kahi fuse uila.
Hoʻohana ʻia kēia fuze me nā mea pahū a i ʻole me ka pūnāwai cocked a me ke koʻokoʻo i hoʻokuʻu ʻia ke hoʻoheheʻe ʻia ka loulou.
Pili ka pine a me ka puna i ka loulou fusible. Ke heheʻe ka loulou, hoʻāla ʻia ka mīkini hoʻokuʻu ʻana, e lele i waho ka pine.
Hoʻololi fuse
ʻO nā fuse hoʻololi kekahi ʻano o ka fuse uila i hiki ke hoʻomalu ʻia i waho me ka hoʻohana ʻana i kahi mea hoʻololi.
Ma nā noi maʻamau i nā kaiapuni uila kiʻekiʻe, e hoʻomalu ʻoe i ka hala ʻana o nā fuse i ka mana a i ʻole ma ka hoʻololi ʻana i ke kua i ke kūlana a i ʻole.
Push-out fuse
Hoʻohana ʻia nā kinoea boron e hoʻopaʻa i ke kaʻina hana arcing. Hoʻohana ʻia lākou i nā wahi uila kiʻekiʻe, ʻoi aku hoʻi i nā transformers 10 kV.
Ke heheʻe ka fuse, hoʻopau ke kinoea boron i ke arc a kipaku ʻia ma ka lua o ka paipu.
Hoʻopau i ka fuse
ʻO nā fuse drop-out kekahi ʻano o nā fuse huki kahi i hoʻokaʻawale ʻia ai ka loulou fuse mai ke kino fuse. Aia kēia mau fuse i ʻelua mau ʻāpana nui; ʻoki hale a me ka pahu fuse.
Hoʻokomo ka mea hoʻopaʻa fuse i kahi loulou fusible, a ʻo ke kino ʻoki ʻia he kiʻi porcelain e kākoʻo ana i ka mea hoʻopaʻa fuse ma luna a me lalo.
Hoʻopaʻa ʻia ka pahu fuse ma kahi kihi i ke kino ʻoki ʻia a hana ʻia kēia no ke kumu.
Ke heheʻe ka loulou fuse ma muli o ka overcurrent a i ʻole kaapuni pōkole, hemo ka mea hoʻopaʻa fuse mai ke kino o ka ʻoki ʻia ma ka pili luna. ʻO kēia ke kumu i hāʻule ai ma lalo o ka umekaumaha, no laila ka inoa "drop fuse".
ʻO ka hāʻule ʻana o ka fuse holder he hōʻailona ʻike nō hoʻi ua puhi ʻia kahi fuse a pono e hoʻololi ʻia. Hoʻohana mau ʻia kēia ʻano fuse no ka pale ʻana i nā mea hoʻololi uila haʻahaʻa.
Fuse wela
Hoʻohana ka fuse wela i nā hōʻailona wela a me nā mea e pale aku ai i ka overcurrent a i ʻole kaapuni pōkole. ʻO kēia ʻano fuse, i ʻike ʻia hoʻi he ʻoki wela a hoʻohana nui ʻia i nā mea hoʻonaninani wela, e hoʻohana i kahi huila koʻikoʻi e like me ka loulou fuse.
Ke piʻi ka mahana i kahi pae ʻokoʻa, heheʻe ka loulou fusible a ʻoki i ka mana i nā ʻāpana ʻē aʻe o ka mea kani. Hana ʻia kēia i mea e pale ai i ke ahi.
Fuse hiki ke hoʻonohonoho hou
Ua kapa ʻia nā fuses hiki ke hoʻihoʻi hou ʻia, ʻo ia hoʻi, ʻo ka pānaʻi wela maikaʻi (PPTC) polymer fuses, a i ʻole "polyfuses" no ka pōkole, a he mau hiʻohiʻona e hiki ke hoʻohana hou ʻia.
Aia kēia ʻano fuse i kahi polymer crystalline non-conductive i hui pū ʻia me nā ʻāpana kalapona conductive. Hana lākou me ka mahana no ka pale ʻana i ka overcurrent a i ʻole ka pale kaapuni pōkole.
Ke anu, noho ka fuse i loko o ka crystalline moku'āina, ka mea e hoʻopaʻa i nā ʻāpana kalapona pili pili a hiki i ka ikehu ke hele i loko.
Inā nui ka lako o kēia manawa, wela ka fuse, e hoʻololi ana mai kahi ʻano crystalline i kahi kūlana amorphous liʻiliʻi.
ʻOi aku ka mamao o nā ʻāpana kalapona i kēia manawa, e kaupalena ana i ke kahe o ka uila. Ke kahe mau nei ka ikehu ma kēia fuse ke hoʻāla ʻia, akā maʻamau ke ana ʻia ma ka laulā milliamp.
Ke maʻalili ke kaapuni, hoʻihoʻi ʻia ke ʻano kristal paʻa o ka fuse a kahe ʻole ka mana.
Mai kēia hiki iā ʻoe ke ʻike ua hoʻonohonoho hou ʻia nā Polyfuses, no laila ka inoa "resettable fuses".
Loaʻa ia mau mea ma nā lako kamepiula a me ke kelepona, a me nā ʻōnaehana nuklea, nā ʻōnaehana huakaʻi ea, a me nā ʻōnaehana ʻē aʻe kahi e paʻakikī loa ai ka hoʻololi ʻana i nā ʻāpana.
fuse semiconductor
ʻO nā fuse Semiconductor nā fuse wikiwiki loa. Hoʻohana ʻoe iā lākou no ka pale ʻana i nā ʻāpana semiconductor i kahi kaapuni, e like me nā diodes a me nā thyristors, no ka mea ua maʻalahi lākou i nā piʻi liʻiliʻi o kēia manawa.
Hoʻohana maʻamau ʻia lākou i nā UPS, nā relay state solid a me nā kaʻa kaʻa, a me nā mea hana ʻē aʻe a me nā kaʻa me nā ʻāpana semiconductor koʻikoʻi.
Fuse hoʻopaʻa haʻahaʻa
Hoʻohana nā fuse pale pale i nā hōʻailona wela a me nā mea ʻike wela e pale aku i ka piʻi ʻana o ka mana. ʻO kahi hiʻohiʻona maikaʻi o kēia ʻo ka fuse ʻano wela kino (NTC).
Hoʻokomo ʻia nā fuse NTC ma ke kaʻapuni a hoʻemi i ko lākou kūʻē ʻana i nā wela kiʻekiʻe.
ʻO kēia ke kū'ē pololei o nā fuses PPTC. I ka wā o ka mana kiʻekiʻe, ʻo ka hoʻohaʻahaʻa ʻana i ke kūpaʻa e hoʻopiʻi ka fuse i ka mana hou aʻe, e hōʻemi a "hoʻopau" i ka mana e kahe ana.
Fuse Mea Mauna Mauna
ʻO nā fuse mauna i luna (SMD) he mau fuse uila liʻiliʻi loa i hoʻohana mau ʻia i nā kaiapuni haʻahaʻa o kēia manawa me ka palena palena. ʻIke ʻoe i kā lākou mau noi ma nā polokalamu DC e like me nā kelepona paʻa, paʻa paʻa, a me nā kāmera, a me nā mea ʻē aʻe.
Ua kapa ʻia ʻo SMD fuses a chip fuses a hiki iā ʻoe ke ʻike i nā ʻano kiʻekiʻe o kēia manawa.
I kēia manawa, loaʻa i nā ʻano fuse āpau i ʻōlelo ʻia ma luna nei kekahi mau hiʻohiʻona hou e hoʻoholo ai i kā lākou ʻano. Hoʻopili kēia i ka manawa i helu ʻia, ka volta helu, ka manawa hana fuse, ka hiki ke haki a me I2T waiwai.

Pehea e helu ʻia ai ka helu Fuse
ʻO ka helu o kēia manawa o nā fuses i hoʻohana ʻia i nā mea hana maʻamau i hoʻonohonoho ʻia ma waena o 110% a me 200% o kā lākou helu kaapuni.
No ka laʻana, ua helu ʻia nā fuses i hoʻohana ʻia i nā kaʻa ma 125%, ʻoiai ʻo nā fuses i hoʻohana ʻia i nā transformers e helu ʻia ma 200%, a ua helu ʻia nā fuses i hoʻohana ʻia i nā ʻōnaehana kukui ma 150%.
Eia nō naʻe, hilinaʻi lākou i nā mea ʻē aʻe e like me ke kaiapuni kaapuni, ka mahana, ka naʻau o nā mea i pale ʻia i ke kaapuni, a me nā mea ʻē aʻe he nui.
No ka laʻana, i ka helu ʻana i ka helu fuse no kahi kaʻa, hoʻohana ʻoe i ke ʻano;
Ka helu ʻana o ka Fuse = {Wattage (W) / Voltage (V)} x 1.5
Inā he 200W ka mana a he 10V ka voltage, helu fuse = (200/10) x 1.5 = 30A.
ʻO ka hoʻomaopopo ʻana i ke arc uila
Ma hope o ka heluhelu ʻana a hiki i kēia manawa, pono ʻoe i ʻike i ka huaʻōlelo "electric arc" i nā manawa he nui a hoʻomaopopo ʻoe he mea pono ke pale aku i ka wā e heheʻe ai ka loulou fusible.
Hoʻokumu ʻia kahi arc i ka wā e hoʻopili ai ka uila i kahi āpau liʻiliʻi ma waena o ʻelua mau electrodes ma o nā kinoea ionized i ka lewa. ʻAʻole e pio ke arc ke pio ka mana.
Inā ʻaʻole mālama ʻia ke arc e ka mamao, ka pauka non-conductive a/a i ʻole nā mea wai, pilikia ʻoe i ka hoʻomau ʻana i ka overcurrent ma ke kaapuni a i ʻole ke ahi.
Inā makemake ʻoe e ʻike hou aku e pili ana i nā fuses, e kipa i kēia ʻaoʻao.
