ʻO ka fuse voltage kiʻekiʻe ka mea nāwaliwali loa i hoʻonohonoho ʻia i loko o ka pā mana.Ke kahe ka over-current, e wela a fuse ka element pono'ī, a e wāwahi ʻia ke kaʻapuni e ka hana arc extinguishing medium e pale i nā laina mana a me nā mea uila.Hoʻohana nui ʻia nā fuse i nā mana liʻiliʻi liʻiliʻi me ka uila ma lalo o 35 kV.
Aia ka fuse me ka paipu fuse, ka ʻōnaehana conductive contact, post insulator a me ka pā kumu (a i ʻole ka pā kau ʻana).Hiki ke hoʻokaʻawale ʻia i ka fuse palena palena o kēia manawa a me ka fuse hāʻule.
Hoʻolālā
ʻO ka fuse o kēia pūʻulu he ʻelua post insulators, contact base, fuse tube a me ka base plate.Hoʻokomo ʻia ka pou insulator ma ka pā kumu, hoʻopaʻa ʻia ka noho hoʻopili ma ka post insulator, a kau ʻia ka pahu fuse i ka noho hoʻopili a hoʻopaʻa ʻia, akā ua ʻeha nā pāpale keleawe ma nā ʻaoʻao ʻelua ma ka paipu porcelain, a me ka fuse i ka pahu fuse ua helu ʻia e like me ka nui o kēia manawa.Hoʻokahi a ʻoi aʻe paha fuses i ʻeha ma ke kumu ribbed (helu ʻia i kēia manawa ma lalo o 7.5A) a i hoʻokomo pololei ʻia i loko o ka paipu (ʻoi aku ka nui o kēia manawa ma mua o 7.5A), a laila hoʻopiha ʻia me ke one quartz.Hoʻohana ʻia nā uhi keleawe ma nā ʻaoʻao ʻelua.Ke hala ke au o ka overload a i ʻole ke kaapuni pōkole, e puhi koke ka fuse, a e hana ʻia ke arc i ka manawa like, a e hoʻopau koke ke one quartz i ke arc.Ke pā ka fuse, puhi pū ke kaula o ka pūnāwai a puka i waho o ka pūnāwai, e hōʻike ana ua puhi ʻia ka fuse.E hoʻopau i ka hana.
Nā kuhikuhi no ka hoʻohana ʻana
ʻAno RN1 i loko o ka hale i piha i ke one quartz fuse, kūpono no:
(1) ʻAʻole kiʻekiʻe ke kiʻekiʻe ma mua o 1000 mika.
(2) ʻAʻole ʻoi aku ka kiʻekiʻe o ka mahana o ka mea a puni ma mua o +40 ℃, ʻaʻole i lalo ma lalo o -40 ℃.
ʻAʻole hiki ke hoʻohana ʻia nā fuse RN1 ma nā wahi e hiki mai ana:
(1) ʻO nā wahi i loko me ka haʻahaʻa pili i ʻoi aku ma mua o 95%.
(2) Aia nā wahi e pilikia ai ke puhi ʻana i nā waiwai a me nā pahū.
(3) Nā wahi me ka haʻalulu nui, ke kowali a i ʻole ka hopena.
(4) Nā wahi me ke kiʻekiʻe ma mua o 2,000 mika.
(5) Nā wahi haumia ea a me nā wahi haʻahaʻa kūikawā.
(6) Nā wahi kūikawā (e like me ka hoʻohana ʻana i nā mea uila X-ray).
