Me pēhea te whiriwhiri i te rahi tika o te taura SC mō ngā hononga au-teitei

Parahi SC whakakikoruatia ki te tine Ngā taura taura i ngā rahi kua whakarārangihia, kua rite mō ngā hononga pākahiko au-tiketike me te tohatoha hiko.

Ki te whiriwhiria te taura he, ka tere te puta mai o ngā tohu: he hononga e wera ana, he pūtu e kore e noho papatahi, he piko rānei e wetekina ana i muri i ētahi marama o te wiri. Mō te hunga e whakamahi ana i ngā pākahiko, i ngā inverters, i ngā switchgear, i ngā ara iahiko motuka rānei, mā te tika o te rahi o te taura SC i te wā tuatahi ka penapena i te maha o ngā tuku whakahoki me ngā raruraru pūtāhui. Anei te huarahi e whakatau ai ngā kaihoko me ngā kaiwhakauru.

He aha te tikanga o te tohu "SC" i runga i te taura parahi?

He pūrua parahi ngongo te taura SC me te arero mowhiti, he mea whakapiko ki te taura kua herea hei hanga hononga pūmau. He whakaaro māmā noa iho te whakaingoa: ko te tau i muri i te "SC" ko te wāhanga whakawhiti o te kaiārahi i roto i ngā mirimita tapawha, ā, ko te tau i muri i te raina ko te diameter o te kōhao poutū i roto i ngā mirimita. Hei tauira, ka uru te pūmau SC25-8 ki te kaiārahi 25 mm2 me te pūmau M8. Kia pānuihia te waehere i tēnei ara, ka ngaro te nuinga o ngā whakaaro pohehe.

He rerekē ngā take e whai tikanga ai ngā tau e rua. Ko te rahi o te ara iahiko e whakahaere ana i te pai o te pupuri a te oko i te waea me te nui o te iahiko ka taea e te hononga te kawe me te kore e whakamahana. Me ōrite te kōhao poutū ki te pūtu i runga i tō pae pahi, i tō whati, i tō pū rānei. pūnga pākahikoHe mea noa mā ngā kaihoko te whao i te rahi o te waea, kātahi ka kitea kāore e uru te mowhiti ki te poroporo M10, nō reira me whakaū tonu i ngā āhua e rua i mua i te tono.

Te whakataurite i te rahi o te taura ki te ine waea

Me ōrite te oko ki te ara iahiko e whakapiko ana. Mēnā he nui rawa te oko, kāore e taea e te whakapiko te pēhi i ngā miro kia piri, ka waiho he hononga ātete-teitei ka wera i raro i te kawenga. He iti rawa, ā, kāore e taea te whakauru i te ara iahiko katoa, nō reira ka tapahia, ka whakapikoa rānei ngā miro ki muri, ā, ka heke te kaha kua whakatauria.

Whakamahia te wāhanga whakawhiti i tāia ki te koti taura hei punga māu. Ka honoa he taura 16 mm2 (tata ki te 6 AWG) ki te taura SC16; me SC50 te taura 50 mm2 (tata ki te 1/0 AWG). Mēnā kua tohua tō taura ki te AWG anake, hurihia ki te mm2 i mua i te whiriwhiri, nā te mea he mea hanga ngā taura SC ki ngā oko ine. He tohutoro tere: 10 AWG tata ki te 6 mm2, 4 AWG tata ki te 25 mm2, me te 2/0 AWG tata ki te 70 mm2. Mēnā kei waenganui i ngā rahi e rua te taura, whiriwhiria te taura e ōrite ana ki te taura ine tuturu kaua e whakaawhiwhi ake.

Te pānga o te kawenga o nāianei ki tāu whiringa

Kāore he kotahi te whakatauranga amp o te lug; ko tōna kaha tūturu e whakawhirinaki ana ki te kaiārahi, te kounga o te kume, me te pāmahana mahi huri noa. Heoi anō, ko te rahi o te oko e whiriwhiria e koe mō te waea he rite tonu te iahiko ki te waea, mena ka tika te mahi o te kume. Ka puta ngā raruraru ina whakamahia anō e ngā kaiwhakauru he lug iti "hei whakapuru noa iho." I te 100 A, neke atu rānei, ahakoa he iti noa te pikinga o te ātete pa ka huri hei wera ine, ā, ka tere ake te waikura i te wera, ka piki ake te ātete. He porowhita e mutu ana ki te hononga pakaru.

Mō ngā mahi hiko-teitei tonu pērā i ngā pouaka whakakotahi hiko pūngao rā, ngā kāpata utu hiko EV, ngā teihana whakawhiti hiko rānei, e rua ngā āhuatanga e whai hua ai. Tuatahi, whiriwhiria ngā pū parahi whakakikoruatia ki te tine kaua ki te parahi tahanga; ka ātete te paparanga tine ki te waikura, ā, ka mau tonu te ātete pa ki ngā tau maha o te mahi. Tuarua, whakaūhia te matotoru o te pakitara parahi. Ka rerekē te āhua o ngā pū angiangi, kua tāia i raro i te piko tika, ko ngā pū ngongo hangai, kore hononga rānei, ka mau tonu te āhua me te pupuri i te ātete kia iti.

Rārangi arowhai kōwhiringa mahi

I mua i te tuku ota, tirohia ēnei āhuatanga:

• Whakaūtia te wāhanga whakawhiti o te ara iahiko i te mm2, me te huri mai i te AWG mēnā e tika ana.
• Whakaūtia te whānui o te pou, o te pūtu rānei o te taputapu e tau ai ngā pūtu taura.
• Whiriwhiria te paninga tahanga, te paninga tine rānei, i runga i te taiao; ko ngā wāhi o waho, o te moana, me te makuku me paninga tine tonu.
• Tirohia te roa o te oko kia taea ai e te taputapu kume te whakamahi i tētahi, i ētahi rānei kume katoa.
• Manatokohia kia tutuki te paerewa e hiahiatia ana e tō kiritaki, pēnei i te RoHS mō te rauemi o te ara iahiko.

He pai te utu mō te tauira poto. Whakapirihia tētahi taura ki tō taura, kātahi ka whakamātautau i te kukume me te tirotiro ātete tere. Mena ka mau te hononga, ā, ka noho mātao i raro i te kawenga, kua tika te rahi.

He aha te hiranga o te kounga o te kuru me te rahi

Ahakoa he pai te rahi o te taura, ka hē te mahi mēnā ka kōpikohia ki te mata hē, ki te taputapu kua tawhito rānei. Me kōpiko te oko kia piri, kia kore e kitea he āputa, ā, kāore he aho e puta. Ko te kōpiko hex, he indent rānei mai i te taputapu waipēhi te tikanga mō ngā taura SC neke atu i te 16 mm2. Ka taea te mahi i ngā rahi iti ake me te kōpiko ratchet kounga. I muri i te kōpiko, me whakaatu te oko i te āhua ma, ōrite, ā, kaua te waea e hurihuri, e paheke rānei.

Mō ngā kaihoko e hoko ana i te rahinga nui, pātai atu ki te kaihanga mō te kounga o te rauemi arataki, te matotoru o te whakakikorua mēnā he tine, me te ripanga ine mō ia tauira. Ka tohaina e te kaiwhakarato whai mana he tūtohi rahi katoa e kapi ana i te whānuitanga o te arataki, te kōhao poutū, ngā ine o te oko, me te roa whānui, kia taea ai e tō rōpū hangarau te tohu i te wāhanga tika i mua i te tukunga tuatahi.

Te tika i ngā wā katoa,

Ko te kōwhiringa o te taura SC e whakawhirinaki ana ki ngā tau e toru e whakahaeretia ana e koe: te whakawhiti o te ara iahiko, te whānui o te pou, me te iahiko e haria ana e te hononga. Pānuihia te waehere wāhanga kia tika, taurite ki te taura tūturu kaua ki te whakatau tata, ā, me whakamahi i te parahi whakakikoruatia ki te tine me te matotoru pakitara e tika ana mō tētahi ara iahiko uaua. Me mahi i tēnā, ā, ka noho mātao, ka piri, ka pono hoki ō hononga mō te roanga o te tāutanga. Mena kāore koe i te tino mōhio ko ēhea tauira e pai ana ki tō whānuitanga o ngā taura, tukuna mai ō rahi ara iahiko me ngā ine pou ki tā mātou tīma, ā, ka tūtohu mātou i ngā pou SC me ngā tautuhinga kume mō tō tono.
