WHAKATAKI O TE HUI NGAOHI TEITEI

Ngā pīhi ngaohiko teiteie whakamahia whānuitia ana i roto i ngā whatunga hiko iti te kaha me te ngaohiko iti iho i te 35kV. Ina puta he taumaha rawa, he ara iahiko poto rānei i roto i te pūnaha, ka pupuhi te rewa nā te wera nui, ā, ka tapahia te raina, ka tiakina hoki te whatunga hiko me ngā taputapu hiko. He rite tonu tōna kaupapa mahi ki te kaupapa o ngā fiusi ngaohiko iti. He rite tonu ngā fiusi.
E rua ngā momo o ngā fiusi hiko-tiketike: te whakawhāiti-auau me te whakapoto-auau. Ko te tikanga o te whakawhāiti-auau ko te whakawhāiti i te au o te ara iahiko poto kia tae ki te uara mōrahi, ā, mā reira ka whati te aho i tētahi uara i mua i te uara mōrahi o te au o te ara iahiko poto, ā, ka whakaiti i te kino o te au o te ara iahiko poto ki te aho me ngā taputapu hiko.

1. Te whakaurunga o te fuse taka
Ko te pou ārai he mahi tāutanga, he whakau me te ārai, ā, he uku te rauemi. Ko te ngongo rewa he mahi ārai me te tinei pewa. Ko te paparanga o waho he mea hanga ki te ngongo pepa phenolic, ki te ngongo kakahu karāhe epoxy rānei, ā, ko te paparanga o roto he mea hanga ki te rauemi whakaputa hau pērā i te ngongo pepa maitai, ki te ngongo pepa shellac rānei. Ko ngā pito e rua o te ngongo rewa he hononga o runga, o raro hoki. Ka haere te rewa mā te ngongo rewa, ka mau tetahi pito ki te hononga o raro, ka whakakīia tetahi pito ki te pereti pēhanga ka taea te huri huri noa i te tuaka, ā, ka pēhia te pereti pēhanga ki te pepa maitai puna hei hanga i te hononga o runga. Ka mau te ngongo hanumi i waenganui i te tautoko whakarewa me te ngutu parera. I te wā e tāuta ana, me hanga te ngongo fiusi me te rārangi poutū ki te koki 30°. I muri i te hanumitanga o te rewa, ka huri te pereti pēhanga ki te taha matau i te rakau i raro i te mahi a te puna, ka paheke te hononga o runga mai i te arero o te taupoki ngutu parera, ā, ka huri te ngongo fiusi ki te taha maui i te rakau 3 e tōna ake kaha, ka iri ki raro i runga i te tautoko, ā, ka kiia ka hinga. I muri i te pupuhitanga o te rewa, ā, ka puta he pewa,
Mā te wera o te pewa ka puta he hau i roto i te rauemi kei te pakitara o roto o te ngongo rewa, ka piki te pēhanga i roto i te ngongo, ka makahia te hau ki waho i te tere teitei, ā, ka pupuhihia te pewa ki te taha roa, ā, ka tineia te pewa ina whiti te ia i te kore.
Kia taka te ngongo fiusi, tangohia te ngongo fiusi me te matau whakamahana, ka whakakapia ki te mea hou. Kia whakakorea te hapa, panaia te ngongo fiusi ki te tūranga kati.
He māmā noa te hanganga o te fiusi, ā, he iti te utu. Ko te ngoikoretanga he iti te ia pakaru, ā, ina pupuhihia te rewa, ka rehuhia te mura me te toenga konganuku mai i te ngongo fiusi ki ngā pito e rua.

2. Te Whakataki ofiusi whakawhāiti-auau
Ka whakamahia te waea parahi whakakikoruatia ki te hiriwa hei hiko, ā, ka takai whakarara ki te matua uku hei hanga i te rewa katoa. Ka whakapirihia te hiko ki ngā pōro tine, e whakamahi ana i te pānga whakarewa, ka taea te whakapai ake i te raruraru ka piki rawa te pāmahana whakapā ina iti te iahiko taumaha, ā, he iti noa te pānga o te pōro tine ki te motu i te ara iahiko poto, nā te mea he poto rawa te wā ara iahiko poto. He mea hanga te hiko ki te rauemi uku, ā, kua whakakiia ki te onepu kuata hei whakakī. Ko ngā pito e rua o te ngongo hiko he taupoki parahi hei whakapā.
Ina pāngia te rewa e te ia o te hapa, ka honoa tuatahitia, ka pakaru te āputa iti hei whakaputa i te pewa, kātahi ka whakanuia haeretia te āputa, ka puta te tukanga pakaru, kia mutu rā anō te pakaru o te āputa nā te ngaohiko whakaora, ā, kia motuhia te aho. Nā te kaha o te wehewehenga o te onepu kuata, ka motuhia, ka whakawhāitihia rānei te ia o te ara iahiko poto i mua i te taenga ki te taumata teitei, nō reira ka kiia he fiusi whakawhāiti-iahiko.
Ina tete whakawhāiti i te au o te hikoKa tapahia te raina, ka tineia te pewa i roto i te ngongo fiusi hiri, ā, ka whakamahia whānuitia i roto i ngā taputapu tohatoha hiko o roto. Nā te pānga whakawhāiti iahiko, ka whakaitihia ngā whakaritenga mō te pumau hihiri me te pumau wera o ngā taputapu hiko i roto i te ara iahiko.
