Te Tātari me te Whakaiti i te Haruru o te Pūnaha Hiko i roto i te Tukanga Hoahoa PCB Auau-Teitei

I roto PCB auau-teiteis, ko te haruru o te pūtake hiko he momo pokanoa nui. Ka whakahaerehia e tēnei tuhinga he tātaritanga whānui o ngā āhuatanga me ngā takenga mai o te haruru o te pūtake hiko i roto i ngā PCB auau-tiketike, ā, ka tukuna he otinga mahi me te whai hua i runga i ngā tono hangarau.

A.Tātaritanga o te Haruru o te Pūtake Hiko

Ko te haruru o te pūhiko hiko e pā ana ki te haruru e puta mai ana, e whakararuraruhia ana rānei e te pūhiko hiko tonu. E kitea ana tēnei pokanoa i roto i ngā āhuatanga e whai ake nei:

1. Te haruru tohatoha i puta mai i teārai ā-roto o te pūhiko hiko. I roto i ngā ara iahiko auau-tiketike, ka pā nui te haruru o te pūhiko hiko ki ngā tohu auau-tiketike. Nō reira, ko te whakaritenga tuatahi he haruru-itipūhiko hikoHe rite tonu te hiranga o te whenua ma me te pūnaha hiko.

I roto i tētahi horopaki tino pai, ko te pūtake hiko kakore-āraitanga, ka kore ai he haruru. Heoi, i roto i te mahi, he ātete motuhake kei te pūtake hiko, e tohatohahia ana puta noa i te pūtake hiko katoa, ka hua ake te taupatupatu o te haruru. Nō reira, me whakapau kaha ki te whakaiti i te ātete o te pūtake hiko. He pai ake te whai i tētahi pūnaha motuhake waka rererangi hikomepapa whenuaI roto i te hoahoa ara iahiko auau-teitei, he pai ake te hoahoa i te pūtake hiko i roto i ngā paparanga kaua i roto i te whakatakotoranga pahi, me te whakarite kia whai tonu te koropiko i te ara me te iti rawa o te aukati. Hei tāpiri, ka whakaratohia e te papa hiko heporowhita tohumō ngā tohu katoa i whakaputaina, i whiwhihia hoki i runga i te PCB, mā te whakaiti i te koropiko tohu me te whakaiti i te haruru.

2. Te Whakararuraru Ārai Aratau Noa: E pā ana tēnei momo whakararuraru ki te haruru i waenga i te pūtake hiko me te whenua. Ka puta mai i te whakararuraru i puta mai i te porowhita i hangaia e te ara iahiko kua pakaru me te ngaohiko aratau noa i puta mai i te mata tohutoro noa. Ko te rahi e whakawhirinaki ana ki ngā ārai hiko me ngā ārai aukume, ā, he iti noa iho tōna kaha.

I tēnei horopaki, ko te hekenga o te iahiko (Ic) ka hua ake he ngaohiko aratau-noa i roto i te raupapaporowhita o nāianei, e pā ana ki te wāhanga whiwhi. Mena ko tepapa aukumee tino nui ana, ko te ngaohiko aratau noa i hangaia i roto i te koropiko whenua raupapa ka hoatuhia e te tātai:

Ko te ΔB i roto i te tātai (1) e tohu ana i te huringa o te kaha o te aukume, e inehia ana i roto i te Wb/m²; Ko S te tohu mō te horahanga i roto i te m².

Mō tētahimara hikohiko, i te wā mara hiko mēnā e mōhiotia ana te uara, ka hoatu te ngaohiko whakaoho e te Whārite (2), e tika ana ina L=150/F, iti iho rānei, me F e tohu ana i teauau ngaru hikohikoi roto i te MHz. Mena ka hipa atu i tēnei rohe, ka taea te whakangawari i te tatau i te ngaohiko whakaawe mōrahi penei:

3. Te Whakararuraru Āpure Aratau Rerekē: E pā ana tēnei ki te whakararuraru i waenga i te pūtake hiko me teraina hiko whakauru me te whakaputangāI roto i te hoahoa PCB tūturu, i kite te kaituhi he iti noa iho tōna pānga ki te haruru o te pūtake hiko, nō reira ka taea te waiho i konei.
4. Te Whakararuraru i waenganui i ngā RainaE pā ana tēnei momo pokanoa ki te pokanoa i waenga i ngā raina hiko. Ina he kaha tauutuutu (C) me te hiko tauutuutu (M1-2) i waenga i ngā ara iahiko whakarara e rua, ka puta te pokanoa i roto i te ara iahiko pokanoa mēnā he ngaohiko (VC) me te iahiko (IC) i roto i te ara iahiko pūtake pokanoa:
   1. Ko te ngaohiko e honoa ana mā te aukati capacitive ka hoatuhia e te Whārite (4), ko RV te uara whakarara o teātete tata-mutungame teātete pito tawhitio teara iahiko kua whakararuraruhia.
   2. Ātete raupapa mā te hononga ā-whakaoho: Mena he haruru aratau noa kei roto i te pūtake whakararuraru, ka puta te whakararuraru i waenga i ngā raina i roto i te aratau aratau noa me te aratau rerekētanga.
5. Hononga Raina HikoKa puta tēnei āhuatanga ina tukuna e te raina hiko ngā pokanoa ki ētahi atu taputapu i muri i te pānga kite pokanoa hikohiko mai i te AC, i te DC rānei pūtake hikoHe momo ā-korekore tēnei o te pokanoa haruru o te pūtake hiko ki runga ara iahiko auau-teiteingāHe mea nui kia mōhiotia ko te haruru o te pūtake hiko kāore pea i te puta ake i a ia anō, engari ka puta pea i te whakararuraru o waho, ka hua ake ai te taupatupatu (te whakawhiti, te kawe rānei) o te haruru i puta ake i a ia anō, ā, ka pokanoa ki ētahi atu ara iahiko, taputapu rānei.

• Ngā mahi ārai hei whakakore i te whakararuraru o te haruru o te pūtake hiko

I runga i ngā āhuatanga me ngā take o te pokanoa haruru o te pūtake hiko i tātarihia i runga ake nei, ka taea te whakakore motuhake i ngā āhuatanga e hua ake ai te haruru o te pūtake hiko, kia pehia ai te pokanoa. Ko ngā otinga e whai ake nei e taunakihia ana:

• Te aro kiPapa i roto i te kōhaos: Mā roto i ngā kōhao e hiahiatia anawhakatuwheratanga whakairokei runga i tepaparanga tuku hiko hei whakauru i tā rātou haerenga. Mena he nui rawa te whakatuwheratanga o te paparanga mana, ka pā ki te koropiko tohu, ka akiaki i te tohu ki te karo me te whakanui ake i te horahanga koropiko me te haruru. Mena kei te tata tonu ētahi raina tohu ki te whakatuwheratanga, ā, ka tohaina tēnei koropiko, ka taea e te aukati noa te arahi ki te whakawhitiwhiti kōrero.
• Waea Whenua Rawaka mō ngā Taura: Me whai ia tohu i tōna ake koropiko tohu motuhake, me te pupuri i te horahanga tohu me te koropiko kia iti rawa, kia tika ai te tūnga whakarara.
• Te Whakanohonga o te Tātari Haruru o te Pūnaha Hiko: Ka pehi pai tēnei tātari i te haruru o roto o te pūnaha hiko, ka whakarei ake i te pūnahaārai-whakararuraru me te haumaru. He hononga e rua ngā araTātari RF, te tātari i te haruru e puta mai ana i te raina hiko (te aukati i te haruru mai i ētahi atu taputapu) me te haruru e puta ake ana i a ia anō (hei karo i te haruru ki ētahi atu taputapu), tae atu ki te haruru aratau noa whakawhiti-aratau.
• Wehewehenga ManaWhakawhitiwhiti: Ka wehea e tēnei te koropiko whenua aratau-noa o tetaura hiko, taura tohu rānei, e wehewehe ana i te iahiko koropiko aratau-noa i hangaia i ngā auau teitei.
• Te Whakahaere Hiko: Mā te whakaora i tētahi pūnaha hiko kia ma ake ka taea te whakaiti i te haruru o te pūnaha hiko.
• Waea: Me waiho ngā rārangi tāuru me ngā rārangi tāuru o te pūtake hiko kia matara atu i te taha o te papa hiko-kore kia kore ai e puta te irahiko me te pokanoa ki ētahi atu ara iahiko, taputapu rānei.
• Ngā Pūhiko Hiko Analog me ngā Pūhiko Mamati Motuhake: He tino tairongo ngā taputapu auau-tiketike ki te haruru mamati, nō reira me wehe ngā mea e rua, ā, me hono tahi ki te tomokanga o te pūhiko. Mena me whiti te tohu i ngā rohe analog me te mamati, ka taea te whakatakoto i tētahi koropiko puta noa i te tohu hei whakaiti i te horahanga koropiko.
• Kaua e taupatupatu ngā Pūhiko Hiko Motuhake i waenga i ngā Papa Rerekē: Ngāna kia whakararahia kia kore ai e ngāwari te hono atu o te haruru o te pūhiko hiko mā te kaha pirinoa.
• Wehea ngā Wāhanga Tairongo: He tino tairongo ngā wāhanga pēnei i ngā koropiko maukati-wāhanga (PLL) ki te haruru o te pūtake hiko, ā, me waiho kia matara rawa atu i te pūtake hiko.
• Te Whakatakotoranga o te Taura Hiko: Mā te whakatakoto i tētahi aho hiko ki te taha o te aho tohu, ka taea te whakaiti i te koropiko tohu me te whakaiti i te haruru.
• Te Whakatakotoranga Ara Ārai: Hei ārai i te haruru kua kohia mai i te pokanoa o te pūtake hiko i runga i te papa hiko me te pokanoa o te pūtake hiko o waho, ka taea te whakatakoto i te ara ārai ki runga i te ara pokanoa (haunga te irahiko), kia taea ai te karo i te haruru ki te whenua, me te karo hoki i te pokanoa ki ētahi atu taputapu me ngā taputapu.

Hei Whakamutunga:Ka whakararuraru te haruru o te pūhiko hiko, ahakoa i ahu tika mai, i ahu kore rānei, i te pūhiko hiko. Ina pehia tōna awe ki te pūhiko hiko, me whai i tētahi mātāpono whānui: whakaitihia te pānga o te haruru o te pūhiko hiko ki te pūhiko hiko, me te whakaiti anō hoki i te awe o ngā āhuatanga o waho, o te pūhiko hiko rānei ki te pūhiko hiko hei ārai i te hekenga o te haruru o te pūhiko hiko.
