He aha te pānga o te ōwehenga whakawhiti hiko ki te pūnaha hiko?

He aha te ōwehenga o te whakawhiti?

 

Ko te ōwehenga whakawhiti o te whakawhiti hiko e pā ana ki te ōwehenga ngaohiko i waenga i te takai ngaohiko-tiketike (HV) me te takai ngaohiko-iti (LV). Ina koa, e tohu ana i te ōwehenga o te ngaohiko whakatauranga i te taha tuatahi (e tohuhia ana ko te taha ngaohiko-tiketike, ko te taha whakauru rānei) ki te ngaohiko whakatauranga i te taha tuarua (e tohuhia ana ko te taha ngaohiko-iti, ko te taha putanga rānei).

 

Mā te pāngarau, ka taea te whakaatu i te ōwehenga whakawhiti (K) o tētahi whakawhiti penei:

 

K=Ngaohiko Whakatauria i te taha Ngaohiko Teitei/Ngaohiko Whakatauria i te taha Ngaohiko Iti

 

 

Me pēhea te tatau i te ōwehenga whakawhiti o te whakawhiti hiko?

 

 

He maha ngā tikanga tatau mō te ōwehenga whakawhiti o ngā whakawhiti hiko:

 

 

1. Te Tātai i te Ōwehenga Hurihanga mā te Hurihanga Koiri Tuatahi-ki-Tuarua:

 

Tātai: Ōwehenga Whakawhiti = Ngā Hurihanga Pōkai Tuatahi ÷ Ngā Hurihanga Pōkai Tuarua

 

Tauira: Mena he 1,000 ngā hurihanga o te koiri tuatahi o te whakawhiti hiko, ā, he 2,000 ngā hurihanga o te koiri tuarua, ko te ōwehenga o te Whakawhiti Hiko he 1:2.

 

 

2. Te Tātai i te Ōwehenga Whakawhiti mā ngā Ngaohiko Whakauru me ngā Ngaohiko Putanga:

 

Tātai: Ōwehenga Ngaohiko = Ngaohiko Tuatahi ÷ Ngaohiko Tuarua

 

Tauira: Mena he 220V te ngaohiko tuatahi o te whakawhiti hiko, ā, he 110 V te ngaohiko tuarua, ko te ōwehenga ngaohiko he 2:1.

 

 

3. Te Tātai i te Ōwehenga Whakawhiti mā te Mana Whakataurite o te Whakawhiti:

 

Tātai: Ōwehenga whakawhiti=tohu pūtake (te kaha whakatauranga o te whakawhiti x te ngaohiko tāuru) ÷ te ngaohiko putanga

 

Tauira: Mena he mana whakatauranga tō te whakawhiti hiko he 1,000 VA, he ngaohiko tāuru he 220 V, ā, he ngaohiko putanga he 110 V, ko te ōwehenga whakawhiti hiko he 2:1.

 

 

4. Te Hononga i waenganui i te Ōwehenga Hurihanga me te Ōwehenga Ngaohiko

 

He rite tonu te kaha hiko whakaawe (EMF) i roto i te takai tuatahi (taha tāuru) me te takai tuarua (taha putanga) o te whakawhiti hiko ki te maha o ngā hurihanga i roto i ia takai. Nō reira, ko te ōwehenga o te ngaohiko tāuru i te taha tuatahi ki te ngaohiko putanga i te taha tuarua he rite ki te ōwehenga hurihanga.

 

 

I te tatau i te ōwehenga o te whakawhiti hiko, ka taea te whiriwhiri i te tikanga tika i runga i ngā tawhā me ngā horopaki o te whakawhiti hiko e mōhiotia ana.

 

Te Pānga o te Tauwehenga Whakawhiti ki te Pūnaha Hiko

 

 

1. Te Pūmautanga o te Ngaohiko

 

Ka pā tika ngā panonitanga o te ōwehenga whakawhiti hiko ki te pumau o te ngaohiko o ngā pūnaha hiko. Ina koa, ko te pikinga o te ōwehenga whakawhiti ka piki ake te ngaohiko, ko te hekenga ia o te ōwehenga ka heke te ngaohiko. I roto i ngā mahi mahi, me whakarite tika te rahi o te rerekētanga o te ōwehenga whakawhiti kia mau tonu ai te pumau o te ngaohiko o te pūnaha ki roto i ngā rohe e whakaaetia ana.

 

 

2. Te kaha whakawhiti hiko

 

Ka pāngia hoki te kaha whakawhiti hiko o te pūnaha e ngā whakarerekētanga ōwehenga whakawhiti hiko. Ka whakaitihia te iahiko whakatauranga o te whakawhiti hiko e te hekenga o te ōwehenga whakawhiti hiko, ā, ka heke pea te kaha kawenga. I te wā kotahi, ka pāngia te mana tauhohe i roto i te pūnaha e ngā whakarerekētanga ōwehenga. Nō reira, me arotake pai ngā pānga ki te kaha whakawhiti hiko i te wā o ngā whakarerekētanga ōwehenga.

 

 

3. Ngā Tūponotanga Haumaru

 

Ko ngā whakawhiti hiko i roto i ngā pūnaha hiko e whakamahi ana i ngā matua whakakikoruatia mō te hanganga takai. Ko te whakarerekē i te ōwehenga whakawhiti me whakarerekē anō i te rerenga aukume katoa o te matua. Mā te whakamahinga hangarau hē ka nui rawa te rerenga o te matua, ka puta he mōrearea haumaru pēnei i te rahunga o te whakamarumaru, te wera rawa rānei o ngā taputapu.

 

 

4. Ngā Pānga ki ngā Horopaki Whakahaere Motuhake

 

I ngā āhuatanga motuhake (hei tauira, te whakamātautau me te tiaki i te pūnaha hiko i te wā hanga), me whakarerekē pea te ōwehenga o te whakawhiti hiko hei whakapai ake i te mahi a te pūnaha. Heoi, me aromatawai pakari aua whakarerekētanga i ōna pānga ki te pumau whānui me te haumaru mahi o te pūnaha hiko.

 

 

Me whiriwhiri te ōwehenga whakawhiti i runga anō i ngā taumata ngaohiko whatunga, ngā tauira rerekētanga kawenga, me ngā whakaritenga whakahaere ōhanga. Hei tawhā nui i roto i te hoahoa, te whakahaere, me te tiaki pūnaha hiko, ka pā tika te whirihoranga whaitake o te ōwehenga whakawhiti ki te pumau o te ngaohiko, te arotau i te whai huatanga o te pūngao, me te haumaru o ngā taputapu. Ko ngā whakatikatika ki te ōwehenga whakawhiti me whai whakaaro whānui ki te āhua whatunga, ngā āhuatanga kawenga, me ngā here tuku ōhanga hei whakaiti i ngā mōrearea pea pēnei i ngā ia e rere ana me te hinganga o te ngaohiko.
