Eia nā ʻano uwea he nui, akā hiki ke hoʻokaʻawale ʻia ka mea maʻamau i nā uwea haʻahaʻa haʻahaʻa a me nā kaula uila kiʻekiʻe, akā pehea e ʻike ai i nā ʻelua?Wahi a kekahi poʻe he 250V, a ʻōlelo kekahi he 1000V.Pehea ʻoe e hoʻokaʻawale ai i ka volta kiʻekiʻe a me ke kaomi haʻahaʻa?
Wahi a nā kūlanaʻoihana o Kina, ua hoʻokaʻawaleʻia nā mea uila i ka volta kiʻekiʻe a me ka haʻahaʻa haʻahaʻa: ka uila kiʻekiʻe: nā mea hana me ka uila ma luna o 250V i ka honua;ka uila haʻahaʻa: nā mea hana me ka uila ma luna o 250V i ka honua.E like me ka 2009 power line safety regulations, hoʻokaʻawale ʻia ka hana uila i ka volta kiʻekiʻe a me ka uila haʻahaʻa
ʻO nā lako uila uila kiʻekiʻe: ʻo 1000V ka pae uila a ma luna;nā lako uila uila haʻahaʻa: aia ka pae uila ma lalo o 1000V;
ʻO ka maʻamau, pili ka laina uila kiʻekiʻe i ka laina 3 ~ 10kV;ʻO ka laina uila haʻahaʻa e pili ana i ka laina 220 / 380 V.
ʻO ke ala e hoʻokaʻawale ai i ka volta o ka uea uila kiʻekiʻe e nā maka ʻōlohelohe penei:
1. E ʻike i ka pae uila.
I loko o ka ʻoihana mana o Kina, ʻo 220 V, 380 V, 1000 V, 10000 V, 35 000 V, 110 000 V, 220 000 V, 500 000 V, a pēlā aku. e like me ka uila haʻahaʻa, no ka uila o ka hale;a ma luna o 35000 V he volta kiʻekiʻe, hoʻohana nui ʻia no ka lawe mana.Aia ma waena o nā mea ʻelua ke kaomi waena.Pono e kuhikuhi ʻia ʻo ka hoʻopā ʻana i nā uea kiʻekiʻe-voltage a i ʻole ka hana ʻana i nā hana ola ma lalo o ka laina he pilikia nui.
2. E hoʻomaopopo i nā laina uila haʻahaʻa.
ʻO ka laina uila haʻahaʻa waho he mau hiʻohiʻona maopopo
1) ʻO ka maʻamau, ʻaʻole ʻoi aku ka nui o ka pou sima ma mua o 5 mika.
2) Ua like ka mānoanoa o nā uea, a ʻo ka heluna o nā uea he 4. ʻO ia ke kumu o ka hoʻohana ʻana o nā uea haʻahaʻa haʻahaʻa i ka ʻōnaehana ʻehā ʻekolu.Inā loaʻa kēia mau hiʻohiʻona, hiki ke hoʻoholo ʻia he 380 V ka laina laina o ka uea a ʻo 220 v ka puʻe uila (ʻo ka puʻupuʻu ka laina i ka volta honua, ʻo ka volta laina ka volta ma waena o nā laina ʻelua)
3. E hoʻomaopopo i nā laina uila a me nā laina kiʻekiʻe.
He mau hiʻohiʻona maopopo nō hoʻi nā laina uila uila a me ke kiʻekiʻe
1) Inā like ka mānoanoa o nā uea, ʻo ka helu o nā uwea he mau 3. ʻO ia ke kumu e hoʻohana mau ai nā laina hoʻouna i ka hoʻouna ʻana i ʻekolu-phase.Inā loaʻa kēia mau hiʻohiʻona, hiki ke hoʻoholo i ka uea he 10000 volts.
2) Inā ʻokoʻa ka mānoanoa o ka uea, ʻo ka helu o nā laina mānoanoa he 3, a ʻelua wale nō uea lahilahi, i manaʻo ʻia aia ma ke kūlana kiʻekiʻe loa.ʻO kēia no ka mea ʻaʻole hoʻohana ʻia ka uea lahilahi no ka lawe ʻana i ka mana, akā no ka pale ʻana i ka uila, ʻike ʻia hoʻi ʻo ka uila uila.Inā loaʻa kēia mau hiʻohiʻona, hiki ke hoʻoholo ʻia he laina kiʻekiʻe ka uila.
4. E hoʻomaopopo hou i ka laina uila kiʻekiʻe.
I mea e hoʻomaikaʻi ai i ka hiki ke hoʻoili, hoʻohana maʻamau nā uea kiʻekiʻe-voltage i nā conductors split.Ma ka ʻōlelo maʻamau, hoʻohana ʻia kekahi uea no hoʻokahi pae.I kēia manawa, hoʻohana ʻia kekahi mau pūʻolo uea e pani i ka mea mua.I ka ʻike ʻana i kēia, ua maʻalahi ka hoʻokolokolo ʻana i ka pae volta o ka uea.1) He 110000 volts hoʻokahi māhele me ka uwea hoʻokahi;2) hoʻokahi māhele me nā uea ʻelua he 220000 volts;3) he 500000 volts hoʻokahi māhele me nā uea ʻehā.
I kā mākou hui ʻana i kēlā me kēia lā me nā laina kiʻekiʻe-voltage, akā i mua o nā laina haʻahaʻa a me nā laina haʻahaʻa, pono mākou e makaʻala.I kēlā me kēia makahiki, helu ʻia ka poʻe i make i ka haʻalulu uila, no laila ʻaʻohe ʻano o ke kelepona i hoʻohana ʻia, pono mākou e hoʻohana i ke kelepona maʻamau me ka hōʻoia maikaʻi.I mea e hoʻomaikaʻi ai i ka maikaʻi o nā huahana, hana ʻia nā huahana e like me nā kūlana aupuni (GB / JB) a me ka International Electrotechnical Commission (IEC).Ua hala ka ʻoihana i ka ISO9001: 2008 international standard certification, i loaʻa ka laikini hana huahana ʻenehana a me ka China National Compulsory Product Certification (CCC certificate).I waena o lākou, ʻo ka ʻenehana hana o ke kaula XLPE aia i ka mua o ka ʻoihana, I mea e hahai pono ai i ke kūkulu ʻana o ka State Grid, ua kūʻai pū aku ka hui i ka 35kV cross-linked cable production line, one-step silane cross-linked production. laina a me nā laina hana uwea holomua ʻē aʻe.ʻAʻohe ʻano o ke kelepona, hāʻawi mau ʻo Zhujiang cable iā ʻoe i ka maikaʻi maikaʻi loa!
