ʻAʻole ʻoi aku ka nui o ka hoʻolālā PCB maʻamau ma mua o 10 A, a i ʻole 5 A. ʻOi aku i ka hale a me nā mea hoʻohana uila, ʻo ka mea maʻamau ka hana mau o ka PCB ʻaʻole i ʻoi aku ma mua o 2 A

Ka Papa Hana 1: Hoʻolālā ma PCB

No ka ʻike ʻana i ka mana o ka PCB i kēia manawa, hoʻomaka mākou me ka hoʻolālā PCB. E lawe i kahi PCB papalua i laʻana. ʻO kēia ʻano papa kaapuni maʻamau he ʻekolu ʻāpana: ʻili keleawe, pā, a me ka ʻili keleawe. ʻO ka ʻili keleawe ke ala e hele ai ka manawa a me ka hōʻailona ma ka PCB. E like me ka ʻike o ke kula kiʻekiʻe, hiki iā mākou ke ʻike e pili ana ke kūʻē ʻana o kahi mea i ka mea, ka ʻāpana cross-sectional, a me ka lōʻihi. No ka holo ʻana o kā mākou manawa i ka ʻili keleawe, ua paʻa ka resistivity. Hiki ke manaʻo ʻia ka ʻāpana cross-section ka mānoanoa o ka ʻili keleawe, ʻo ia ka mānoanoa keleawe i nā koho hana PCB. Hōʻike maʻamau ka mānoanoa keleawe ma OZ, ʻo ka mānoanoa keleawe o 1 OZ he 35 um, 2 OZ he 70 um, a pēlā aku. A laila hiki ke hoʻoholo maʻalahi i ka wā e hāʻawi ʻia ai kahi au nui ma ka PCB, pono e pōkole a mānoanoa ka uwea, a ʻo ka mānoanoa o ka mānoanoa keleawe o ka PCB, ʻoi aku ka maikaʻi.

I ka ʻenekinia maoli, ʻaʻohe kūlana koʻikoʻi no ka lōʻihi o ka wili. Hoʻohana maʻamau i ka ʻenekinia: ka mānoanoa keleawe / ke piʻi ʻana o ka mahana / ke anawaena uea, ʻo kēia mau hōʻailona ʻekolu e ana i ka hiki ke amo o ka papa PCB.

ʻO ka ʻike wili PCB: hoʻonui i ka mānoanoa keleawe, hoʻonui i ke anawaena uea, a me ka hoʻomaikaʻi ʻana i ka wela o ka PCB hiki ke hoʻonui i ka mana o ka PCB i kēia manawa.

No laila, inā makemake au e holo i kēia manawa o 100 A, hiki iaʻu ke koho i ka mānoanoa keleawe o 4 OZ, e hoʻonoho i ka laula i 15 mm, nā ʻaoʻao ʻelua ʻaoʻao, a hoʻohui i kahi wela wela e hōʻemi i ka piʻi ʻana o ka mahana o ka PCB a hoʻomaikaʻi. kūpaʻa.

Ke ala ʻelua: terminal

Ma waho aʻe o ka wili ma ka PCB, hiki ke hoʻohana ʻia nā pou wili.

E hoʻoponopono i kekahi mau pahu e hiki ke kū i ka 100 A ma ka PCB a i ʻole ka pūpū huahana, e like me nā nati mauna ʻili, nā pahu PCB, nā kolamu keleawe, a me nā mea ʻē aʻe. Ma kēiaʻano, hiki i nā au nui ke hele i nā uwea.

03

ʻO ke ala ʻekolu: ka pahu keleawe maʻamau

Hiki ke hoʻopilikino ʻia nā pā keleawe. He hana maʻamau i ka ʻoihana ka hoʻohana ʻana i nā kaola keleawe e lawe i nā au nui. No ka laʻana, hoʻohana nā mea hoʻololi, nā keʻena kikowaena a me nā noi ʻē aʻe i nā pahu keleawe e lawe i nā au nui.

Kaʻina 4: Kaʻina hana kūikawā

Eia kekahi, aia kekahi mau kaʻina hana PCB kūikawā, a ʻaʻole hiki iā ʻoe ke ʻike i kahi mea hana ma Kina. He ʻano PCB ʻo Infineon me kahi hoʻolālā keleawe 3-layer. ʻO ka ʻaoʻao o luna a me lalo he mau ʻāpana uwila hōʻailona, ​​a ʻo ka papa waena he ʻāpana keleawe me ka mānoanoa o 1.5 mm, i hoʻohana kūikawā ʻia e hoʻonohonoho i ka mana. Hiki ke liʻiliʻi ka nui o kēia ʻano PCB. Kahe ma luna o 100 A.
