Te Mahi a te Pātene Wehe Utaina

Tepana kawengaHe taputapu whakawhiti i waenganui i te kaiwawao hiko me te pana wehe. He taputapu tinei pewa ngāwari tōna, ka taea te tapahi i te iahiko kawenga kua whakatauria me te iahiko taumaha, engari kāore e taea te tapahi i te iahiko ara-poto.

Tepana kawengaKo te nuinga o te wā e whakamahia ana hei wawahi me te kati i te iahiko kawenga, ā, ka taea hoki te whakamahi i te pana kawenga me te fiusi ngaohiko-tiketike hei whakakapi i te kaiwawao hiko. Nā te mea he ngāwari te whakamahi i te pana kawenga, ā, he whaitake te utu, he whānuitia te whakamahinga o te pana kawenga i roto i te pūnaha whatunga tohatoha 10kV. He mea nui te whiriwhiri tika i ngā pana kawenga i roto i te hoahoa hei whakarite i te mahi haumaru me te pono o te whatunga hiko.

Ko te tukanga mahi o te pana kawenga penei: ina whakatuwheratia te parai, i raro i te mahi a te puna whakatuwhera, ka huri te rakau matua ki te taha matau. I tetahi taha, ka neke ake te piston mā te pūnaha crank-slider hei pēhi i te hau; i tetahi atu taha, mā roto i ngā huinga e rua o te pūnaha hononga wha-pae. Ka whakatuwherahia te maripi matua e te pūnaha tuku kua hangaia, kātahi ka panaia te maripi tinei pewa hei whakatuwhera i te hononga pewa, ā, ka pupuhihia te pewa e te hau pēhi i roto i te rango mā te pūwero.

He rite te kaupapa mahi a te pana hiko kawenga ngaohiko teitei ki te pana hiko pakaru. I te nuinga o te wā, ka tāutahia he taputapu tinei pewa māmā, engari he tino māmā tōna hanganga. E whakaatu ana te pikitia i tētahi pana hiko kawenga pehanga teitei hau pēhi. Ko tana tukanga mahi penei: ina whakatuwheratia te parai, i raro i te mahi a te puna whakatuwhera, ka huri te rakau matua ki te taha matau. I tetahi taha, ka neke ake te piston mā te pūnaha crank-slider hei pēhi i te hau.

I tētahi atu ringa, mā roto i te pūnaha tuku e rua ngā huinga hononga wha-pae, ka whakatuwheratia tuatahitia te maripi matua, kātahi ka panaia te maripi tinei-āwhata kia whakatuwheratia te hononga āwhata, ā, ka pupuhi te hau kōpeke i roto i te rango i te āwhata mā roto i te pūwero. I te wā e kati ana, mā roto i te pou matua me te pūnaha tuku, ka huri te mata matua me te mata tinei-āwhata ki te taha matau i te wā kotahi, ā, ka kati tuatahitia te hononga āwhata; ka huri tonu te pou matua, kia kati ai te hononga matua i muri mai.

I te wā e kati ana, ka rongoa te puna whakatuwhera i te pūngao i te wā kotahi. Nā te mea kāore e taea e te pana kawenga te wawahi i te iahiko poto-arahiko, ka whakamahia pinepinetia me te fiusi ngaohiko teitei-whakawhāiti-iahiko. Ko te mahi whakawhāiti-iahiko o te fiusi whakawhāiti-iahiko e kore e taea te whakaoti i te mahi wawahi i te arahiko, engari ka whakaitihia hoki te wera e puta mai ana i te iahiko poto-arahiko me te mana hiko.
