I roto i te ao hangarau motuka matatau, he mea nui te whakaurunga o ngā wāhanga hiko-teitei mō te mahi tino pai me te whai hua. Ko te whakamahana whakamatao PTC (Positive Temperature Coefficient) tētahi o ngā wāhanga e aro nuihia ana. Nā tēnei auahatanga whakamiharo i huri te huarahi e whakamahia ai e ngā waka te pūngao, kia pai ai te taraiwa ahakoa i roto i ngā āhuatanga huarere kino. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā āheinga o ngā whakamahana whakamatao PTC, ā, ka whakamāramahia ngā painga e kawea mai ana e rātou, me te arotahi ki ō rātou hoa hiko-teitei, e mōhiotia whānuitia ana ko ngā whakamahana whakamatao hiko-teitei (HV).
Akohia mōNgā Whakamahana Whakamatao PTC:
Ko ngā whakamahana whakamatao PTC he taputapu i hangaia hei whakamahana i te whakamatao miihini mā te whakamahi i te kaupapa o te whakamahana ātete hiko. Ko te tauwehenga pāmahana pai e pā ana ki te āhuatanga o ētahi rauemi e piki ake ana te ātete hiko i te pikinga o te pāmahana. Mā tēnei āhuatanga ka taea e te whakamahana PTC te urutau ki ngā hiahia wera rerekē me te whakaū i tōna ake pāmahana, me te whakarite kia rite tonu te putanga wera me te whakarerekē.
Awhitia te Hangarau Ngaohiko Teitei:
Ka whakamahia e ngā whakamahana whakamatao ngaohiko-tiketike, e mōhiotia ana ko ngā whakamahana whakamatao ngaohiko-tiketike, te mana o te pūnaha pēhanga-tiketike hei whakarato i te mahi me te whai huatanga pūngao nui atu i ō rātou hoa ngaohiko-iti tuku iho. Ka taea e ngā whakamahana whakamatao ngaohiko-tiketike te mahi i runga i te neke atu i te 300 volts, e whakarato ana i te putanga mana pai ake me ngā wā urupare pai ake, e pai ai mō ngā waka hou e piki haere ana te hiahia pūngao.
Te whai huatanga o te pūngao me ngā painga taiao:
Tewhakamahana whakamatao ngaohiko teiteiKua hangaia hei whakanui ake i te whai huatanga o te pūngao me te whakaiti i te whakapaunga mana katoa o te waka. Mā te whakawhiti wera tere me te whai hua, ka āwhina i te whakapoto i ngā wā whakamahana miihini, te whakaiti i te whakapaunga wahie me te whakaiti i ngā tukunga hau kino. Hei tāpiri, ka taea e ēnei whakamahana te tohatoha wera pai puta noa i te kāpini, kia pai ai te noho o te pāhihi me te whakaiti i te moumou pūngao.
Ngā mahi ngāwari:
Ko tētahi o ngā āhuatanga tino pai o ngā whakamahana whakamatao PTC, tae atu kiNgā whakamahana whakamatao HV, ko tō rātou kaha ki te whakarato i ngā momo mahi whakahaere. Ka taea te whakauru i ēnei whakamahana ki ngā momo whirihoranga pūnaha hiko, tae atu ki ngā miihini hiko, ngā miihini ranu me ngā miihini tikanga, mō ngā momo momo waka me ngā tauira. Ko te ngāwari o te whakamahana whakamatao ngaohiko-tiketike ka horapa ki te hototahi ki ngā momo pūtake hiko rerekē, tae atu ki te mana pākahiko, ngā miihini whakaputa hiko i runga i te papa, me ngā pūnaha hiko whakahou, ka whakarei ake i tōna pūmanawa mō te whānuitanga o ngā tono.
Te Pono me te Haumarutanga:
Ko te haumaru te mea nui mō ngā wāhanga katoa o te motuka, ā, he tino pai ngā whakamahana whakamatao PTC i tēnei āhuatanga. Mā te whakamahi i ngā pūnaha whakahaere whakauru me ngā tikanga aroturuki matatau, ka whakarite kia haumaru, kia whai hua hoki te mahi. Hei tāpiri, kua rite te whakamahana whakamatao ngaohiko-tiketike ki ngā tikanga tiaki pēnei i te whakahaere iahiko, te ngaohiko me te pāmahana hei ārai i te wera nui, te pakaru rānei. Ka āwhina ēnei āhuatanga haumaru ki te whakapai ake i te pono me te roa o te oranga o te whakamahana, me te whakarato hoki i te rangimarie o te hinengaro mō ngā kaipupuri waka me ngā kaihanga.
Te mahi a ngā whakamahana whakamatao PTC i roto i te whakahiko:
I te mea kua nekehia nuitia te ahumahi motuka ki te hiko, he mea tino nui ngā whakamahana whakamatao PTC, inā koa ngā whakamahana whakamatao ngaohiko teitei. He mea nui tā rātou hei tautoko i te whakawhiti mai i ngā miihini tahunga ā-roto tuku iho ki ngā waka hiko me ngā waka ranu, e whakarato ana i te whakamahana e tika ana me te kore e whakararu i te whai huatanga o te pūngao. Mā te whakauru i ngā whakamahana whakamatao PTC ki roto i ngā papa hiko, ranu rānei, ka taea e ngā kaihanga te arotau i te whakamahinga pūngao me te whakarei ake i te wheako taraiwa whānui.
hei whakamutunga:
Nā te whakatinanatanga o ngā whakamahana whakamatao PTC, inā koa ngā whakamahana whakamatao HV, kua hurihia te huarahi e whakahaere ai ngā waka i te pāmahana, e whakarite ana i te whai huatanga o te pūngao me te whakapai ake i te whakamarie o ngā pāhihi. Nā ō rātou kaha mana whakamiharo, te urutau me ngā āhuatanga haumaru, ko ngā whakamahana whakamatao ngaohiko teitei te heke mai o ngā pūnaha whakamahana motuka. I te tipu haere tonu o te umanga, ehara i te mea he mea tika anake te whakamahi i te hangarau ngaohiko teitei, engari he taahiraa anō hoki ki te nekenekehanga pumau me te taiao.
