Nā kūlana hana maʻamau
◆Ambient ea wela wela
ʻAʻole ʻoi aku ka mahana o ka ea ma mua o 40 ° C, ʻo ka awelika waiwai i ana ʻia i loko o 24 mau hola ʻaʻole e ʻoi aku ma mua o 35 C, a ʻo ka awelika waiwai i ana ʻia i hoʻokahi makahiki e emi iho i kēia waiwai.
ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o ka ea he 5 C.
◆Kiʻekiʻe
ʻAʻole ʻoi aku ke kiʻekiʻe o ke kiʻekiʻe o ke kahua hoʻonohonoho i ka 2000m.
◆Ke kūlana lewa
ʻAʻole ʻoi aku kona haʻahaʻa haʻahaʻa ma mua o 50% ma ka wela kiʻekiʻe o 40 ° C
Hiki ke loaʻa kahi haʻahaʻa haʻahaʻa kiʻekiʻe ma kahi haʻahaʻa haʻahaʻa, no ka laʻana, a hiki i 90% ma 20C.
Ma lalo o kēia mau kūlana, hiki mai ka condensation haʻahaʻa ma muli o nā loli wela.Me ka ʻole o ke kūkākūkā ʻana me ka mea hana, ʻaʻole hiki ke hoʻokomo ʻia ka fuse ma kahi me ka noe paʻakai a i ʻole ka waiho ʻana i nā ʻoihana ʻenehana.
◆Uila
ʻAʻole ʻoi aku ka nui o ka ʻōnaehana uila ma mua o 1 10% o ka volta fuse i helu ʻia.
No ka fuse me ka voli helu helu o 690V AC a me 250V 1440V DC, ʻaʻole ʻoi aku ka nui o ka volta ʻōnaehana ma mua o 105% o ka volta helu o ka fuse.
Nā kūlana hoʻonohonoho maʻamau
◆Wāwai hoʻokomo
ʻO ka papa hoʻonohonoho o ka fuse ka papa I.
◆Ka pae pollution
ʻAʻole e emi ka degere anti pollution o ka fuse ma mua o ka pae 3.
◆Keʻano hoʻokomo
Hiki ke hoʻokomo ʻia ka fuse ma ka ʻaoʻao, horizontally a i ʻole obliquely ma ka wahi hana me ka ʻole o ka haʻalulu nui a me ka haʻalulu hopena.
Ka wehe ʻana a me ka hoʻohana ʻana i ka ʻāpana
ʻO ka loulou fuse no ka fuse he loulou fuse me ka manaʻo maʻamau a me ka hiki ke wāwahi piha, ʻo ia hoʻi ka loulou fuse "gG".
Nā hiʻohiʻona hana a me ke kumu hana
Aia ka fuse i ke kumu fuse a me ka loulou fuse.Hoʻokumu ʻia ka waihona fuse me ka hoʻopili kumu, ka pā kumu, a me nā mea ʻē aʻe.
Ke hoʻokomo ʻia ka fuse i ke kaapuni, i ka wā i ʻoi aku ka nui o ka manawa e hele ana i ka fuse ma mua o kahi waiwai no ka manawa kūpono, e hoʻoheheʻe ʻia ka hoʻoheheʻe ʻana i loko o ke kino fuse, a hana ʻia ke arc i ka wā e hui ʻia ai ka fuse e ke one quartz i ka fuse. e pio ka paipu, i mea e hiki ai ke hoopau i ke kaapuni.
Ke puhi ʻia ka hoʻoheheʻe ʻana, e puka mai ka hōʻailona ma ka loulou fuse, e hōʻike ana ua puhi ʻia ka loulou fuse.
No ka fuse i lako me ka impactor, ke hoʻoheheʻe ʻia ka hoʻoheheʻe ʻana, e hoʻopuka koke ka mea hoʻoheheʻe.Pono ka mea hoʻohana e hoʻokomo i kahi micro-switch a i ʻole kahi mea hoʻouna hōʻailona kūpono (i koho ʻia a kūʻai ʻia e ka mea hoʻohana) i mua o ka hopena, a laila hiki ke loaʻa ka hōʻailona i makemake ʻia ma hope o ka hui ʻana o ka fuse.

5. Hoʻokomo, hoʻohana a mālama i ka fuse
E hoʻokomo ʻia ka fuse i loko a i ʻole i loko o kahi keʻena ʻaʻole e hoʻopilikia ʻia e ka ua a me ka hau, a ʻaʻole e hōʻike ʻia a hoʻokomo ʻia ma kahi maʻalahi e hoʻopā. ʻoi aku ka mamao o ke kolo ma mua o 10 mm. Ma ke kaapuni, ua ʻōlelo ʻia ka ʻāpana kea o ka uea hoʻohui e like me ka waiwai ma ka Papa 4.

Ke puhi ʻia ka loulou fuse, pono e hoʻololi ʻia kahi loulou fuse hou me ke kumu hoʻohālike like, ka nui a me ka helu o kēia manawa e like me ka loulou fuse kumu ma mua o ka uea keleawe.
ʻO ka hoʻololi ʻana i nā loulou fuse e hoʻokō ʻia e nā ʻoihana e hoʻohana ana i nā mea lawe fuse kūikawā.
Ke hoʻololi nei i ka loulou fuse, pono e hoʻokō ʻia ma lalo o ke ʻano o ka ukana ʻole, ʻoi aku ka maikaʻi ke ʻoki ʻia ka mana.ʻAʻole ʻae ʻia ka hoʻohana ʻana i ka fuse e ʻoki a hoʻopili paha i ka ukana ke hoʻohana ʻia ka hoʻololi.Ma hope o ka hoʻololi ʻana i ka loulou fuse, e hōʻoia i ka pili pono ʻana o ka pilina ma waena o ka loulou fuse a me ka pilina kumu.
Ke hoʻopau i ka lako mana a hoʻololi i ka loulou fuse, e ʻoluʻolu e wehe i ka lepo a me nā lepo ʻē aʻe ma ke kumu fuse, ʻoi aku ka pili o ke kumu, i hana maikaʻi ka fuse.
I ka wā o ka hana ʻana, e nānā pinepine ʻia ka mea hōʻailona o ka loulou fuse i ʻike i ka hana hoʻokahi a i ʻole ka hana nalo i ka manawa.
Ka lawe ʻana a me ka mālama ʻana i ka fuse
E mālama ʻia ka fuse mai ka ua a me ka hau i ka wā o ka lawe ʻana a me ka mālama ʻana.ʻAʻole ʻoi aku ke kiʻekiʻe o ke kiʻekiʻe kulu manuahi o ka fuse pahu holoʻokoʻa ma mua o 250mm.
E mālama ʻia nā fuses ma kahi me ka ea a me kahi maloʻo, a ʻaʻole ʻoi aku ke kiʻekiʻe o ke kiʻekiʻe ma mua o ʻeono papa.
Wehe a nānā i ka fuse
Ma hope o ka wehe ʻana, e nānā mua inā pili ka papa inoa o ka fuse me ka papa inoa hoʻopili a me ka hōʻailona ma ka pahu pahu, a laila e nānā inā hemo a hāʻule paha ka mea hoʻopaʻa ma ke kumu fuse a hāʻule paha. nahā a māhā paha ka loulou fuse, e nānā inā e kahe ana ke one quartz i loko o ka pahu fuse, a e nānā inā pulu a hoʻouka ʻia paha e ka wai.Inā loaʻa nā kūlana i luna, ʻaʻole hiki ke hoʻohana ʻia ka fuse, a e hoʻopili ʻia ka mea hana i ka manawa.
Aia i loko o ka pahu fuse ka palapala hōʻoia huahana, ka papa inoa paʻi a me ke aʻo hana.
Kauoha kauoha
Ke kauoha ʻana i nā fuse, e hōʻike ʻia ke kumu hoʻohālike, ka kikoʻī, ka nui a me ka helu o kēia manawa o nā loulou fuse pili.Hiki ke kauoha kaawale ke kumu fuse a me ka loulou fuse.
No nā fuses o nā kikoʻī kūikawā a me nā pae o kēia manawa, e kūkākūkā ka mea hana i ka wā e kauoha ai.
