Ka taea e ngā SPD te tiaki i ngā momo raruraru hiko katoa?
Kua hangaia ngā SPD hei tiaki i te nuinga o ngā ngaru rangitahi, engari he rohe kei runga i tō rātou whakatauranga. Tērā pea kāore e taea te tiaki katoa i ngā ngaru tino kaha, i ngā whiunga uira tika rānei mēnā kāore te taputapu i te whakatauranga tika. Mō te tiakitanga whānui, ka taea te whakamahi i te huinga o ngā momo SPD rerekē.
Te Rerekētanga i waenga i te Momo 1, Momo 2 me te Pūrere Tiaki SPD
Momo 1 SPD kua hangaia hei whakahaere i ngā ngaru hiko tauwhiro nui-pūngao, e puta pinepine ana i ngā whiunga uira tika. Ko ēnei taputapu ka tāutahia ki te tomokanga hiko matua o te whare, hei whakarato i te tiakitanga tuatahi mai i ēnei āhuatanga tino kino. Ka taea e ngā SPD Momo 1 te whakahaere i ngā iaru ngaru tae atu ki te 100 kA, neke atu rānei, mā te whakamahi i ngā wāhanga tiaki kaha-teitei pērā i ngā ārai āputa hau hei whakarite kia tiakina te pūnaha i ngā ngaru nui.
Momo 2 SPD Ka tukuna he tiaki mō ngā wāhanga tohatoha o te pūnaha hiko, e aro ana ki ngā ngaru toenga kei te noho tonu pea i muri i te tiakitanga Momo 1. Ina tāutahia ki ngā panera tohatoha, ki ngā panera-iti rānei, kua hangaia ngā SPD Momo 2 hei whakahaere i ngā ia ngaru iti, tae atu ki te 20-40 kA ia wāhanga. Kei roto i ēnei taputapu ngā wāhanga pēnei i ngā Metal Oxide Varistors (MOV) me ngā Gas Discharge Tube (GDT) hei whakarato tiaki e tika ana mō ngā taputapu whai muri i te tiakitanga ngaru tuatahi.
T1+T2 SPD Ka whakakotahi i ngā painga o ngā SPD Momo 1 me Momo 2, ka whakarato i te tiakitanga whānui mō te pūnaha hiko katoa. Mā te tāuta i tētahi SPD Momo 1 ki te tomokanga hiko matua hei aro atu ki ngā ngaru hiko-nui me tētahi SPD Momo 2 i roto i te pūnaha tohatoha mō te tiakitanga tuarua, ka whakarite ngā SPD T1+T2 i te parenga pakari ki te whānuitanga o ngā ngaru hiko. He pai rawa atu tēnei huarahi whakakotahi mō ngā taiao mōrearea nui pēnei i ngā pokapū raraunga, ngā hōhipera, me ngā whare ahumahi, he mea nui te tiakitanga ngaru hiko whānui.
Ina hiahiatia he maha ngā taputapu tiaki ngaru hiko (SPD) hei tiaki i tētahi tāutanga, he mea nui kia taurite te mahi tahi. Mena nō ngā kaihanga rerekē ngā SPD, he mea nui kia tirohia mēnā he hototahi tetahi ki tetahi. Ko te kaiwhakauru me ngā kaihanga o ngā taputapu ngā puna tohutohu pai rawa atu hei whakarite kia tika te mahi tahi o ngā SPD.
He aha te Pūrere Tiaki Ngaru (SPD)?
Ko te Pūrere Ārai Ngaru (SPD), e mōhiotia ana ko te parenga ngaru, he mea hanga hei tiaki i ngā taputapu hiko mai i ngā ngaru hiko me ngā ngaohiko tere. He wāhanga nui tēnei i roto i te pūnaha tiaki tāutanga hiko. Ka honoa te SPD i te taha whakarara ki te ara iahiko tuku hiko o ngā kawenga e tiakina ana e ia, ko te tikanga ka taea te whakamahi i ngā taumata rerekē o te whatunga tuku hiko. Ina honoa i te taha whakarara, ka whakaatuhia e te SPD he aukati teitei i raro i ngā āhuatanga noa. Heoi, ina puta he ngaohiko tere, ka heke te aukati o te SPD, ka taea te huri i te ia ngaru mā roto i te taputapu me te matara atu i ngā taputapu tairongo. Ka āwhina tēnei tukanga ki te aukati i te kino o ngā taputapu hiko utu nui mā te whakarite kia whakahaerea haumaru te kaha ngaru nui.
