Ko ngā rerekētanga me ngā āhuatanga o te whakamahinga i waenga i te Ring Main Unit me te Metal Clad

Ka whakamahia te Wāhanga Matua Mowhiti i roto i te pūtake hiko whatunga mowhiti hei hono i ngā pūtake hiko e rua, i ngā wāhanga rānei o tētahi kāpata pana. Ko te mahi matua ko te wehewehe i ngā wāhanga e rua, me te mahi kotahi me te rahi iti. Ko te kāpata waenga he momo kāpata pana e whakamahia ana e ngā kaiwhakamahi mutunga, me ngā mahi katoa me te rahinga nui. He maha ngā momo kāpata waenga, ka taea te wehewehe ki ngā kāpata pana e haere mai ana me ngā kāpata pana e haere atu ana, ngā kāpata ine, ngā kāpata whakawhiti hiko, me ngā kāpata whakawhiti hiko kua whakamahia. Ka taea te whakauru i ngā pana i roto i ngā kāpata waenga ki ngā taputapu tiaki aunoa. Mēnā ka pā mai he aituā, ka tukuna e te taputapu tiaki he tohu hei whakamutu i te mahi a te pana, ka tapahia te pūtake hiko. Ko te nuinga o ngā kaiwawao hiko korehau VS1 e whakamahia ana i roto i te kāpata. Nā te whakamahinga rerekē, he tino rerekē te hanganga me te kōwhiringa wāhanga o ngā mea e rua.

I roto i te pūnaha tuku hiko me te tohatoha, me matua hoatu te ine i te tuku-teitei kaua ki te ine i te ngaohiko iti; ka taea anake te whakaaro ki te ine i te ngaohiko iti ina kore he huarahi hei tāuta i te ine ki te taha ngaohiko teitei; i tēnei wā, me whakanoho te kāpata ine ngaohiko iti ki te taha "mua". , Arā, ko te mua o te raina taumai ngaohiko iti me te tuara o te whakawhiti hiko, engari kāore e taea te noho i raro i te tiakitanga o te kāpata raina taumai ngaohiko iti te kāpata ine, nō reira i raro i ngā āhuatanga noa, me noho i raro i te tiakitanga o te pana ngaohiko teitei o te whakawhiti hiko. I tēnei wā, ka taea te whakamahi i te kāpata whatunga mowhiti me te kāpata pokapū.

I tēnei wā, kāore e taea anake te whakauru i te Wāhanga Matua Mowhiti ki ngā taputapu hiko whakakotahi pana kawenga-fius, engari me ngā pūwā hiko hoki, pērā i te XGN o te whare, Schneider's SM6, Siemens 8DJH, ABB's SAFE, me ētahi atu, ā, ka taea te whakauru i te parenga tuarua ki tētahi taputapu tiaki rorohiko iti. Heoi, he rohe kawenga tō te pūwā hiko kua tāutahia ki te wāhanga matua mowhiti, ā, he rerekē ngā rohe o te wāhanga matua mowhiti o ia kaihanga. Pērā i te Wāhanga Matua Mowhiti Schneider RM6, ko te parenga o te pana ngaohiko teitei o te whakawhiti hiko he nui ake, he ōrite rānei ki te 2000KVA, ā, me whakamahi te parenga pūwā hiko + VIP300. Kāore e herea te kawenga ki ngā raina e haere mai ana, e haere atu ana hoki o te kāpata matua.

He pono, nā te whanaketanga o te hangarau tuku hiko o nāianei, kua tino whanake haere ngā momo kāpata e rua. Kei te iti haere ngā kāpata pokapū; kei te kaha haere te mahi a te Wāhanga Matua Mowhiti; engari i te nuinga o te wā, ko ngā kāpata pokapū e whakamahia ana i roto i te taputapu whakahaere. Ko te kaiwhakamahi whakamutunga ko ngā taputapu whakahaere, engari he nui te utu; i hangaia te kāpata whatunga mowhiti hei whakaoti rapanga o te tuku hiko me te whakaurunga, ā, he māmā noa iho tana mahi, engari he māmā noa iho tana hanganga, he iti te rahinga, ā, he iti te utu. Nō nā tata nei, kua whānui haere tonu ngā mahi, inā koa he iti te rahi, he ngāwari te tāuta ki roto i te "pouaka whakawhiti", nō reira he tino pai te whanaketanga; i tēnei wā, ehara i te mea ko te Wāhanga Matua Mowhiti anake te kāpata pana whakapā, engari ka taea hoki te whakamahi hei Kāpata pana takahuri ki roto, ki waho hoki, hei kāpata ine, hei kāpata PT.
Nō reira, he uaua ki te kī mēnā ka taea te whakawhiti i ngā mea e rua, nā te kore e ōrite ngā mahi me te mahi a ngā hua o ngā kaihanga rerekē. Mō te whakaiti i ngā utu, he painga anō tō te kāpata whatunga mowhiti. Nā te whanaketanga o te hangarau wae matua mowhiti, ka taea te taupatupatu i te whakamahinga o te wae matua mowhiti me te kāpata pokapū i ngā wā maha. Engari i roto i te pūnaha tohatoha hiko ngaohiko teitei me ngā iahiko nui ake i te 1250A, kāore e taea e te kāpata matua mowhiti te whakakapi i te kāpata pokapū.
