Ko Liper, he kaiwhakarato matua mō ngā otinga rama auaha, e whakanui ana i te hiahia nui mō te tiaki i ngā ngaru hiko i roto i ngā pūnaha rama kāinga me ngā pūnaha rama arumoni. Ko ngā ngaru hiko, e kore e māramahia i te nuinga o te wā, he tūmomo mōrearea nui ki te roa o te ora me te mahi a ngā rama hou.
He aha te Pupuhi Mana?
Ko te ngaru hiko he pikinga ohorere, poto noa iho o te ngaohiko hiko e nui atu ana i te rere paerewa (hei tauira, 100V/240V AC). Ka puta mai ēnei ngaru, e mau ana i te miriona hauwhā o te hēkona, i:
1.Ngā Pānga Uira: Ngā pānga tika, ngā pānga tata rānei ka puta ai ngā ngaru hiko ki ngā raina hiko.
2.Ngā Mahi WhatungaTe whakawhiti taputapu, te whakahohenga o te pēke pūnga, te whakakore hapa rānei.
3.Ngā Pūtake ā-RotoNgā mōtini nui (ngā ararewa, ngā mīhini hiko) e whakaweto ana, e whakaweto ana rānei i roto i te whare.
Te Tūkino Huna ki tō Rama
Ka puta he kino nui, he kino tāpiri rānei i ngā ngaru nui:
1.Te Rahunga TonuTe wera ohorere o ngā taraiwa LED, ngā kaiwhakahaere, ngā pūtake hiko rānei.
2.Te Mahi Whakaheke: Ka pōturi haere te roa o te ora o te mea ka pā mai te kino, ka kimokimo, ka huri te tae, ka heke rānei te kanapa.
3.Te Kino o te Pūnaha Whakahaere: E whakararu ana i ngā whatunga rama atamai, ngā pūoko, me ngā pūnaha whakaiti i te mārama.
4.Ngā Tūponotanga HaumaruNgā tūponotanga ahi pea mai i ngā wāhanga kua pakaru.
5.Te Wā Whakamutu me te Whakakapinga Utu NuiNgā utu tiaki me te whakakapinga o ngā taputapu kāore i whakamaheretia.
I muri i te pānui i ēnei kōrero, tera pea kei te whakaaro koe me pēhea te karo i ēnei raruraru... Ā, ko te mea pono, kua whakatakotohia e te International Electrotechnical Commission (IEC) he paearu mārama mō te ārai i te ngaru i roto i ngā rama mā roto iIEC 60598-1me ngā paerewa mahi motuhake pērā iIEC 61547Ko ngā whakaritenga matua ko:
1.Ngā rama o roto: E hiahiatia ana kia tu atu i ngā ngaru Taumata 2 (he mea noa i roto i ngā whare):
·Raina-ki-Raina:1 kV
·Raina-ki-Papa Whenua (Papa Whenua): 2 kV
2.Ngā Rama o Waho: E pāngia ana e ngā mōrearea teitei ake (uira, taura roa), me whiwhi ārai mate Taumata 3, Taumata 4 rānei:
·Raina-ki-Raina: 2 kV, 4 kV rānei
·Raina-ki-Papa Whenua (Papa Whenua):4 kV, 6 kV rānei – He mea nui mō ngā pou, ngā taha o te whare, ngā whenua rānei.
He aha te mahi a Liper hei whakarite kia haumaru, kia roa hoki te ora o ngā rama?
E aro nui ana a Liper ki te haumaru i ngā wā katoa, nō reira ka arotahi ā mātou kaihangarau ki te tāpiri i ngā taputapu tiaki ngaru, ā, ka whakamātautau ā mātou ahorangi i ā mātou rama i roto i te rūma whakamātautau EMC kia tino teitei ake ai te paerewa o te taumata ngaru o ā mātou rama.
1. Tāpirihia ētahingā taputapu tiaki ngarui te wā e hanga ana i te papa PCB.
·Ngā Varistor: te whakapūmau i te ngaohiko mā te huri i te iahiko ngaru.
·Ātete whakakāpupuhi tere hei ārai i ngā aituā haumaru kino atu (pērā i ngā ahi).
·Te Whakaiti Ngaohiko Whakawhiti (TVS): tino tere te urupare, e tiaki ana i ngā IC tairongo i roto i ngā taraiwa/pūmana. He iti ake te whakahaere pūngao.
·Ngā ine aratau noa: kia kore ai e piki ohorere te ia engari kia piki mārire, kia mimiti hoki te kaha ohorere. (e tika ana mō ngā rama tiriti, ngā rama waipuke me ngā rama hiko teitei)
（i mua i te whakamahi i te inductor aratau noa）
（Whai muri i te whakamahi i te inductor aratau noa）
2. Whakamātauria ngā rama i roto i tā mātou taiwhanga ngaio
·Pūkaha ngaru: he teitei ake te paerewa o te whakamātautau i te paerewa IEC. Mō ngā rama tiriti, ka taea e tātou te eke ki te 10kV i muri i te tāpiri i ngā ārai uira.
·Rūma whakamātautau EMCWhakamātauria te kaha ārai-whakararuraru, me te whakamātautau mēnā ka pā ā mātou rama ki tētahi atu taputapu. Kei raro tēnei whakamātautau i te paerewa CB.
Whai muri i ēnei mahi, ka taea e koe te whakawhirinaki ki te whakamahi i ā mātou rama mō te kaupapa! Ko Liper, he waitohu ka taea e koe te whakawhirinaki ake tonu atu!
