TE WHAKATAURITE MAHI O NGĀ TAPUTAPU WHAKAWHAKA SF6 ME TE KAIWHAKAWHA HIRIKOI

Whakataurite Mahi o te Taputapu Whakakotahi SF6 me te Kaiwhatu Ara Iahiko

Te pakaru i te mahi a te whakawhiti kore-kawenga

Ko te nuinga o ngā āhuatanga kawenga o te waeine matua mowhiti i roto i te pūnaha tohatoha hiko ko te wehenga me te kati o te whakawhiti tohatoha. Ko te kaha whānui ko te 315-1250 kVA, ā, ko te iahiko kore-kawenga o te whakawhiti tohatoha he tata ki te 2% o te iahiko kua whakatauria. Ina pakaru te whakawhiti kore-kawenga, mena he kaha te kaha tinei pewa o te kaiwawao ara iahiko, ā, he momo pūngao o waho te tikanga tinei pewa, ka puta te āhuatanga o te aukati iahiko tinei pewa kaha i mua i te kore, ka hua ake he ngaohiko tapahi nui. Mena ka whakamahia he kaiwawao ara iahiko, nā tōna kaha tinei pewa, kua hangaia hei pakaru i te iahiko poto nui. Ina pakaru te iahiko iti o te whakawhiti kore-kawenga, tera pea ka puta he tinei pewa kaha, ka hua ake he ngaohiko tapahi nui. I tēnei whakaaro, kāore e pai kia whakamahia ngā kaiwawao ara iahiko me ngā kaha tinei pewa kaha. Ā, mō te pana kawenga SF6, nā runga i ngā āhuatanga hiko o te hau SF6, ina whakamataohia te pewa i roto i te hau SF6, ka mau tonu te hiko tae noa ki te iti o te pāmahana, ā, he iti te tapahi iahiko i mua i te whiti kore o te iahiko, ā, ka karohia te ngaohiko nui. Nō reira, he pai ake te mahi a te pana kawenga SF6 ki te wawahi i te whakawhiti kore-kawenga i tērā o te kaiwawao ara iahiko SF6, ā, he pai ake te kaiwawao ara iahiko SF6 i te kaiwawao ara iahiko korehau.

Tiakina te mahi a ngā whakawhiti tohatoha

Mō te tiaki i ngā whakawhiti hiko tohatoha, he pai ake te whakamahi i te huinga pana kawenga SF6 + fiusi i ngā kaiwawao hiko, ā, i ētahi wā kāore e taea e te mea whakamutunga te mahi tiaki whai hua. E whakaatu ana te whakamātautau ara iahiko poto ina whakapotohia te whakawhiti hiko kua rumakina ki te hinu, kia kore ai e pahū te tāke hinu, me tango te hapa i roto i te 20 mirihekona. Mā te whakawhāiti i te uara iahiko ara iahiko poto ka taea te tiaki pai i te whakawhiti hiko. Ko te wā pakaru katoa o te kaiwawao hiko e toru ngā wāhanga, ko te wā mahi tiaki whakawhiti + te wā mahi ā-roto o te kaiwawao hiko + te wā whakakorikori, e toru ngā huringa e hiahiatia ana (60 mirihekona), nō reira kāore e taea te tiaki pai i te whakawhiti hiko. Ahakoa ngā whakawhiti momo-maroke he pai ake i te whakamahi i ngā kaiwawao hiko nā te tere o te mahi tiaki o ngā fiusi.

Te mahi whakarite tiaki whakawhiti

Ko te parenga o te kaiwawao hiko i te pito matua o te whatunga tohatoha whatunga mowhiti (te kaiwawao hiko whāngai 10kV o te teihana hiko) e whakatakotoria ana kia 0 hēkona mō te whati tere, 0.5 hēkona mō te iahiko nui, me te 0.5 hēkona mō te raupapa kore. Mena ka whakamahia he kaiwawao hiko i roto i te waeine matua mowhiti, ahakoa kua whakatakotoria ki te 0.5 hēkona, he uaua ki te whakarite kia kore te kaiwawao hiko pito tuatahi e mahi tuatahi nā te marara o te wā mahi ā-roto o te kaiwawao hiko. Kāore te fiusi whakawhāiti iahiko e pāngia e te hekenga ngaohiko i puta mai i te ara iahiko poto, ā, ka taea te tango i te hapa i roto i te wā poto rawa me te kore e puta he pekepeke.
