Hoʻopili 3Pin Denemaka i ke kaula mana huelo C13
Ua hoʻokumu ʻia ʻo Dongguan Komikaya Electronics Co., Ltd. i ka makahiki 2011, Specialized i ka hana ʻana a me ka hoʻomohala ʻana i nā ʻano mea like ʻole o nā huahana uila, a me ka USB Cable,HDMI, VGA. Uea Leo, Uea Uea, Uea uea kaa, Uila Mana, Uea Hoihoi, Hookui Kelepona, Mana Hoopono, Uea Uea, Earphone a pela aku me ka lawelawe OEM/ODM nui, Loaʻa iā mākou nā lako hana kiʻekiʻe. , ka hoʻokele kūlana kiʻekiʻe a me kahi hui hana akamai.
He aha ke ʻano o ka uea maikaʻi
ʻO ka māhele ikaika o kēia manawa e pili pinepine i ka laina mana AC380 / 220V, e like me nā kumu, nā lako kukui, nā ea, nā mea hoʻomehana, nā mea kīhini, a me nā mea'ē aʻe. mai wehewehe nui.
No laila, pehea e hoʻokolokolo ai i ke kū a hāʻule paha o ka mea hana uila uila ikaika?
Hoʻokahi, hoʻohana maʻamau no ka hoʻonani hale o ka uea BV ikaika i hoʻohana pinepine ʻia i ke kaʻina hana o ka hoʻonaninani hale.
He nui na ano o ka uea, maʻamau hoʻohana uea hōʻailona BVBVR, BVVB, RVV, ka okoa mea penei: Elua, uea mea hana BV uea pehea e ike?
1. Length identification Hiki ke olelo aku, basically a pau uila uea ma ka makeke, ua lawa ole 100 mika, maona i ka uila uea o 98 mika ma luna, i ka mea hana o ka lunamanao. ka lōʻihi, ʻaʻole pilikia wale nō, akā hiki i ka hale kūʻai ke ʻike iā ʻoe he keʻokeʻo liʻiliʻi.
ʻAe, ua ʻike ka ʻoihana o kēia manawa i ke ʻano ana, aia ka hewa i loko o 1 mika:
Penei ke ano.
A: ka helu o nā uea i ka mokulele ākea
B: ka helu o nā uwea ma ka mokulele kū pololei
C Ka lōʻihi: ka lōʻihi mai waho aʻe o ka pahu a i ka ʻaoʻao mamao loa o ka pahu i loko
Penei ke kumu helu helu: Ka helu o na uwea i mika = Ka helu o na uwea A x Ka helu o na uwea B x ka loa C x 3.14
No ka laʻana, ka mea hoʻokele BV2.5, ma hope o ke ana mua ʻana, ʻo ka helu o A he 12; Ka helu o B: 16; ʻO ka lōʻihi o C: 16.5 kenimika, ʻo ia hoʻi, 0.165 mika, hiki ke helu ʻia ka lōʻihi o ka uea e like me: 12×16×0.165×3.14 = 99.47 mika.
Hoʻohana pū kēia ʻano hana no nā uea huinaha 4 a me 6 mau huinaha.
2. Hōʻike anawaena laina
'Ōlelo pinepine mākou he 2.5 huinahā BV laina, i ʻike nui ʻia ʻo ka uea kumu hoʻokahi a i ʻole uea keleawe keleawe, e pili ana i ka uea keleawe, ʻo ia hoʻi, ʻo ka ʻāpana cross-sectional o ka laina COPPER uea BV2.5 he 2.5 square millimeters. A laila, e like me ka ʻāpana o ka pōʻai, ʻo ke anawaena o ka uea keleawe ma kahi o 1.78mm, ʻo ia ke kūlana aupuni.
Pehea ka nui? E hoʻohana i nā calipers vernier:
Eia hou, he mea nui e hoʻomaopopo i ke ana ʻana mai nā ʻaoʻao ʻelua o ka reel, ʻoiai inā he nui ke anawaena uea, ʻaʻole ia he manaʻo ua lawa ke anawaena uea holoʻokoʻa. No ka nui o nā huahana shoddy, mai ka hoʻomaka ʻana o ʻekolu mika ʻaʻohe pilikia, akā ma hope o ʻekolu mau mika i hoʻomaka e lahilahi, i Z ma hope o ʻekolu mau mika a i ʻole, a hoʻihoʻi i ke anawaena maʻamau, ʻo ia ke kumu o ka mea hana i ke kaʻina hana. o ka hana kaha kii uwea keleawe. No laila ke kūʻai ʻana i ka uea, nui nā lima kahiko e nīnau i ka luna: "Ua huki ʻia ka uea i waena?" Inā makaʻu ka luna e ʻōlelo ʻaʻole, i kēia manawa, e makaʻala nui.
3, ʻike keleawe
ʻO ke kumu kūʻai nui o ka uea ʻo ia ka mea hoʻokele metala, aʻo ka GB plastic copper wire e hoʻohana ana i ke keleawe oxygen-free e like me ka conductor. ʻO nā uea maʻamau ʻole e hoʻohana i nā metala me ka haʻahaʻa keleawe ma ke ʻano he mea hoʻokele, e like me ke keleawe, ke keleawe galvanized, ke keleawe-ʻaʻahu keleawe (ke keleawe i uhi ʻia me kahi papa keleawe), ʻo ia hoʻi ke alumini keleawe, ke kila keleawe, etc. ʻoi aku ka kūpaʻa ma mua o ke keleawe, e hoʻoulu ai i ka wela nui a me nā pōʻino.
Pehea ʻoe e haʻi ai?
ʻO ka ʻōlelo maʻamau, ʻoi aku ka melemele o ke kala, ʻoi aku ka liʻiliʻi o ke keleawe. He melemele maʻemaʻe ke keleawe, a he ʻulaʻula iki ke keleawe. Hiki iā ʻoe ke hoʻohana i nā pliers e ʻoki, e nānā i ka ʻāpana, e ʻike inā kūlike ke kala, ma ka liʻiliʻi he maʻalahi ke hoʻoholo inā he alumini i kāwili ʻia ke keleawe a pēlā aku.
4. hōʻike hoʻokaʻawale
E nānā mua i ka mānoanoa o ka pū uea (insulator). ʻO ka maʻamau maʻamau 1.5-6 uea square me ka ʻole o ke keleawe oxygen e koi i ka mānoanoa sheath (ka mānoanoa insulation) o 0.7mm. Inā mānoanoa loa, no ka nele o ke anawaena o loko. ; A laila e hoʻoholo ana i ka maikaʻi o ka insulator, ka huahana hoʻopunipuni, maʻalahi ke haki i ka pahu uea ma ka huki ʻana me ka lima.
5. ʻIke kaumaha
ʻO nā uea maikaʻi maikaʻi ka mea maʻamau i loko o ka pae kaumaha i kuhikuhi ʻia. Eia kekahi laʻana,ʻo ke kaumaha o ka laina BV1.5 i hoʻohana mauʻia he 1.8-1.9kg no 100m;
ʻO ke kaumaha o ka laina BV2.5 he 3-3.1kg no 100m;
ʻO ke kaumaha o ka laina BV4.0 he 4.4-4.6kg no 100m.
ʻAʻole kaumaha nā uea maikaʻi ʻole, ʻaʻole lōʻihi, a i ʻole he haole loa ke kumu keleawe o ka uea.
