ʻO kahi hana koʻikoʻi o ke kaula ʻikepili ke hoʻouna i nā hōʻailona ʻikepili. Akā ke hoʻohana maoli mākou iā ia, aia paha nā ʻano ʻike hoʻopilikia ʻino. E noʻonoʻo kākou inā komo kēia mau hōʻailona interfering i loko o ka conductor o ke kaula ʻikepili a hoʻopaʻa ʻia ma luna o ka hōʻailona i hoʻouna mua ʻia, hiki ke hoʻopilikia a hoʻololi paha i ka hōʻailona i hoʻouna mua ʻia, a laila e lilo ai nā hōʻailona pono a i ʻole nā pilikia?
Uea
ʻO ka papa i hoʻopaʻa ʻia a me ka papa alumini alumini e pale a pale i ka ʻike i hoʻouna ʻia. ʻOiaʻiʻo, ʻaʻole i loaʻa i nā kaula ʻikepili ʻelua ʻāpana pale, he nui ka pale pale kekahi, hoʻokahi wale nō, a ʻaʻole loa. ʻO ka papa pale he mea hoʻokaʻawale metala ma waena o ʻelua ʻāpana spatial e hoʻomalu i ka induction a me ka radiation o nā hawewe uila, magnetic a me electromagnetic mai kekahi ʻāina a i kekahi.
ʻO ke kikoʻī, ʻo ia ka hoʻopuni ʻana i nā cores conductor me nā pale e pale aku iā lākou mai ka hoʻopili ʻia ʻana e nā kahua electromagnetic waho / nā hōʻailona hoʻopilikia, a i ka manawa like e pale ai i ka hoʻopili ʻana i nā māla electromagnetic / hōʻailona i nā uea mai ka pālahalaha ʻana i waho.
ʻO ka ʻōlelo maʻamau, ʻo nā kaula a mākou e kamaʻilio nei e pili ana i ʻehā ʻano o nā uea insulated core, nā hui wili, nā kaula pale a me nā kaula coaxial. Hoʻohana ʻia kēia mau ʻano uwea ʻehā i nā mea like ʻole a loaʻa nā ʻano like ʻole o ke kūʻē ʻana i ka interference electromagnetic.
ʻO ke ʻano hui wili ʻia ke ʻano hoʻohana maʻamau o ka hoʻolālā uea. He mea maʻalahi kona ʻano, akā hiki iā ia ke hoʻopau like i ka interference electromagnetic. ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe o ka wili o kāna mau wili wili, ʻoi aku ka maikaʻi o ka hopena pale. ʻO ka mea i loko o ke kaula pale i ka hana o ka hoʻokele a i ʻole ka hoʻokele magnetic, i mea e kūkulu ai i kahi ʻupena pale a loaʻa i ka hopena anti-magnetic interference maikaʻi loa. Aia kahi ʻāpana pale metala i loko o ke kaula coaxial, ʻo ia ka mea nui ma muli o kona ʻano o loko i hoʻopiha piha ʻia, ʻaʻole wale ia He pono i ka lawe ʻana i nā hōʻailona a hoʻomaikaʻi nui i ka hopena pale. I kēia lā e kamaʻilio mākou e pili ana i nā ʻano a me nā hoʻohana ʻana o nā mea pale kelepona.
Aluminum foil Mylar tape: Aluminum foil Mylar tape ua hanaia me ka alumini pepa e like me ke kumu kumu, polyester film e like me ka mea hooikaika, i hoopaaia me ka polyurethane glue, hoolaia i ka wela wela, a oki. Hoʻohana nui ʻia ʻo Aluminum foil Mylar tape i ka pale pale o nā kaula kamaʻilio. ʻO ka pepa alumini ʻo Mylar lipine e pili ana i ka pahu alumini ʻaoʻao hoʻokahi, ka pahu alumini ʻaoʻao ʻelua, ka pahu alumini paʻa, ka pahu alumini wela hoʻoheheʻe, ka lipine alumini alumini, a me ka lipine composite aluminika; Hāʻawi ka papa alumini i ka conductivity uila maikaʻi loa, ka pale a me ka anti-corrosion, hiki ke hoʻololi i nā ʻano koi.
Aluminum foil Mylar tape
Hoʻohana nui ʻia ʻo Aluminum foil Mylar tape no ka pale ʻana i nā hawewe electromagnetic kiʻekiʻe e pale aku i nā hawewe electromagnetic kiʻekiʻe mai ka hoʻopili ʻana i nā conductors o ke kaula e hoʻoulu i ka manawa a me ka hoʻonui ʻana i ka crosstalk. Ke hoʻopā ka hawewe electromagnetic kiʻekiʻe i ka alumini alumini, e like me ke kānāwai o Faraday no ka hoʻokomo electromagnetic, e pili ka nalu electromagnetic i ka ʻili o ka alumini alumini a hoʻoulu i kahi manawa i hoʻoulu ʻia. I kēia manawa, pono ke alakaʻi alakaʻi e alakaʻi i ke au i hoʻokomo ʻia i loko o ka lepo e pale aku i ke au i hoʻokomo ʻia mai ka hoʻopilikia ʻana i ka hōʻailona hoʻouna.
ʻO ka papa i hoʻopaʻa ʻia (pale metala) e like me nā uea keleawe / alumini-magnesium alloy. Hana ʻia ka papa pale metala e nā uwea metala me kekahi ʻano hana wili ma o nā lako wili. ʻO nā mea o ka pale metala he mau uea keleawe (ʻo nā uea keleawe i hoʻopaʻa ʻia), nā uea alumini alumini, nā uea alumini i hoʻopaʻa ʻia i ke keleawe, ka lipine keleawe (plastic coated steel tape), alumini tape (plastic coated aluminum tape), steel tape a me nā mea ʻē aʻe.
Kaha keleawe
E like me ka wili metala, ʻokoʻa ka hana pale ʻana i nā ʻāpana ʻokoʻa, ʻaʻole pili wale ka pale ʻana o ka papa i hoʻopaʻa ʻia i ka conductivity uila, magnetic permeability a me nā ʻāpana hana ʻē aʻe o ka mea metala ponoʻī. A ʻoi aku ka nui o nā papa, ʻoi aku ka nui o ka uhi ʻana, ʻoi aku ka liʻiliʻi o ke kihi wili, a ʻoi aku ka maikaʻi o ka hana pale ʻana o ka papa wili. Pono e hoʻomalu ʻia ka ʻaoʻao braiding ma waena o 30-45 °.
No ka pale ʻana hoʻokahi, ʻoi aku ka maikaʻi o ka uhi ʻana ma luna o 80%, i hiki ke hoʻololi ʻia i nā ʻano o ka ikehu e like me ka ikehu wela, ka ikehu a me nā ʻano ʻano o ka ikehu ma o ka hysteresis loss, dielectric loss, resistance loss, etc. , a hoʻopau i ka ikehu pono ʻole no ka hoʻokō ʻana i ka hopena o ka pale a me ke komo ʻana i nā hawewe electromagnetic.
