KOUNGA ka nui ake te hiahia o te pou me te nuinga o te raruraru na te kiritaki hou!
I muri e whakamārama matua mō ngā tawhā hangarau faufaa:
Mātao Ātete IR ranei e whakahuatia ana te ingoa o te aukati
te mātao. Ka tiakina e IR nga taputapu hiko mai i te ara iahiko poto. Uara IR
i te nuinga o te waa he tino teitei i roto i te whānuitanga o te Mega-ohm ko te Mohm.
Temperature Tauwhakarea ka whakawhirinaki mena ko te dielectric te karaehe 1, te Akomanga 2. He uku ranei
capacitor (tautautefito ki te akomanga 2) he maha tonu te waahanga horahanga, te whakarea i te auau teitei o te tohatoha.
Tauwehenga motumotu (tan δ):ko te DF ranei kua tautuhia hei waahanga mo te ESR me te urupare capacitive. Ko te
ko te raru o te kokorutanga e mohiotia ana ko te tangent o te koki ngaronga me te whakaatu noa i roto i te orau.
Ko nga paerewa mohio e whakaatu ana i te horahanga o te waahanga i etahi waahanga motuhake 120Hz mo te Aluminium
electrolytic me Tantalum capacitors i te mea mo nga kaiwhakaari kiriata he 1 kHz me te 1 MHz mo nga kaitohu uku.
Hauruke Motunga (PD): Ko te rere hiko korakora ranei e piriti he wahi iti o te mātao
i waenganui i rua whakahaere taea electrodes.PD tupu i tetahi wāhi i roto i te pūnaha ārai mātao, i reira te mara hiko
nui te kaha te kaha pākarukarutanga o taua wahi o te material.PD te tuuraa taea tupu i roto i te apoo i roto i
mātao mārō, puta noa i te mata o te tuuraa rauemi e tika ana ki täoke kōtītiti ranei, i roto i ngā mirumiru hau
i roto i te mātao wai ranei a tawhio noa te kawehiko i roto i te hau (mahi kurahauao).

Rauemi Dielectric a te HVC N4700: he rite ki etahi atu kamupene, ko te hiko e whakatau ana i te waahanga nui
Tuhinga o mua. E whakapau ana te HVC i nga tau e 3 me nga miriona taara ki te tarai i te titanate strontium arai, ko te momo N4700. Tenei
Ko nga taonga N4700 e whakarato ana i tetahi waahanga tino pai rawa atu, he tino aukati i te aukati me te tohatoha iti
tauwehe me super roa te ora ki runga ki te tau 20.
Hangarau Whakapūtātanga Tauritenga:
Kia pai ai te mohio o nga kaihoko ki nga taonga a te HVC, ka whakaatuhia e maatau te whakaritenga hangarau a te HVC me te rereketanga o nga waa
waitohu i Uropi me Te Tai Tokerau Amercia.
E Brand Amercian *****
tohaina he potae kōpae uku anake, tohaina he rite ki te rauemi diorectric a te HVC X5F.
Toreretanga Factor hoki X5F he 1.5%;
Ko te waahanga X5F a te HVC ka taea te wehewehe i te Wahanga Tohu ki te 1%.
Whakaatu Ngaohiko Maximun i runga i rārangi 30Kv, 2200pf;
Whakaaturanga a te HVC mo te raarangi (mahinga auau) 50Kv, 3300pf.
Flash Testing 130% o Whakatauria Ngaohiko, rite 30Kv, flash whakamātautau kia 40KvDc.
Ko te kaha o te hiko Hiko ka taea te 150% ki te 200%, te tikanga i te wa e kiia ana ko te ngaohiko kia 30Kv, ka taea e te whakamatautau flash te tu
45Kv ki 60KvDc.
Āhuatanga Temperature: (NP0 ki Z5U)
Ko nga tohu ngawari o te HVC :(N4700, Y5T, Y5U)
Brand Pākehā G ******:
whakahere pūnga Kosi'i anake.
10Kv max te puritanga 8000pf, i HVC kia taua 8000pf, taua rauemi momo N4700;
20kv max te puritanga 4000pf, i taea HVC e 10000pf;
30kv max te puritanga 2700pf, i taea HVC e 3300pf;
40kv max te puritanga 2000pf, i HVC kia taua 2000pf;
50kv max te puritanga 1700pf, i taea HVC e 15000pf (Y5V) me 5000pf (Y5T).
G ******:te whakamahi i N4700 rauemi, e torere ki Factor kia 0.3% max, i nga wa katoa kia HVC a tawhio noa 0.1%, me te kore teitei
atu i 0.2%
G ******:Mātao ātete 10,000mOhm (N4700) min, i taea e te nuinga o te wā HVC 200,000mOhm (N4700) min.
American H Popular Brand **:
whakahere pūnga tatau puku, anake, waihoki whakamahi i roto i Te Tai Tokerau mākete Amercian.
E kore e mohio ki te rauemi uruhanga, toreretanga uara tauwehe kia max 0.5%, i HVC majorly whakamahi N4700 uruhanga
rauemi, toreretanga tauwehe kia 0.1 anake% ki 0.2%, te wā te nuinga 0.1% anake.
North American Hamous Brand H **:
hokona whanui i Amerika Te Tai Tokerau, Russia, Japan me te tuku i nga kopae uku e rua
pūnga iahiko me te pona tatau
Mo nga potae kopae uku, ko te Y5P anake, ko te Y5U kei te waatea te waatea, kaore e tino pai te whakarea i te pāmahana, i te
HVC tuku N4700 mō potae kōpae uku.
Kei te waatea te kaha o te kaha o te hiko, H *** whakaatu ko 20Kv 4700pf (Y5U), i te wa e whakaekea ana e te HVC 50KV 3300pf (Y5T).
Ko te aukati whakaheke he min 1000mOhm, i te mea ko te IRC o te IRC hei 10 000mOhm
Ko te tauwehenga 5% max (Y5P), ko te max o te DF he 2% (Y5U, Y5V)
Pākehā M Brand *****:
Kamupene rongonui o te ao, tohaina te miihini pona tatau i roto i te momo rereketanga, rauemi dieletric i Y5U me
N4700 taumata. Ko te hua o tenei ingoa nui e tino awangawanga ana ki te wariu o te wehenga o te waahanga, ko to raatau taonga ka tino iti te pc ina oti te whakatau
Ngaohiko AC, I te wa e whakaekea ana e te HVC te kounga kounga o te pC iti.
Whiwhi Whiwhi Whiwhi hei <5pC @ AC kua tauTuhia. I tenei wa ka rite te HVC <5pC mo te ahua rite.
Rauemi N4700 me te Ātete Whakaoho> = 1011ohm, Ahakoa ko nga mea a te HVC ake N4700 kia takirua, min 2x1011Ohm
Japanese Brand T Ao Famous **:
Ko tenei kaiwhakanao ko te kaihanga o te komihana o te ao, me te nui o te hanganga rereke
te tipu i te ao, ka whakaputahia e ratau nga miihini kopae tatau, ka waihanga i a raatau ake taputapu uku
hei Z5T, Y5P me Y5S, ko nga mea katoa ko nga rauropi mahana noa, kaore o raatau N4700 taumata rauemi,
whakaekea te kaha nui me te kaha o te kaha hiko. Ahakoa ko te Y5S he momo taonga kaore i te koreutu PB.
Engari kia aro ki teRoHS “EU fakahinohino 2002 / 95 / EC, mata, cadmium, mēkuri, hexavalent chromium, me motuhake
retardants mura e hāngai ana pūkeha-, PBB me PBDE,Kua kore i whakamahia, kahore hoki tono kapea”Mo te teitei
tono ngaohiko, kaua e hiahiatia kia kore e arahi. Engari kaua e arahi i te taonga koreutu mai i nga kaihoko nui. Nui rawa atu
ngaohiko capacitance reiti 50kv 2100pf anake, engari ka kite i te 20kvAC 1080p, ka taea e tenei 20kvAC te rite ki te 80kvDC.
Ahakoa e taea ana e te HVC inaianei ki te hanga 150kvDc (50kvAC), taonga 800pf, he nui ake te kaha o to tatou HVC mo te tono mutunga teitei.
Ko te Aukati Whakatohe kia 100,000mOhm min, i te mea ko te max IR o te HVC he ruarua, he iti kei te 200,000mOhm.
Utu Tauritenga hoki HVC me etahi atu:
Mai i runga ake e mohio ana taatau he tino teitei te kounga o te kounga o te HVC, kei roto tatou i te taua kounga kounga o te waitohu rongonui o te ao
Vishay, TDK, Murata, Morgan etc… Ae kei te 20% ki te 30% te utu iti ake mo te nuinga.
Leadtime Tauritenga hoki HVC me etahi atu:
Ko te wa arahi a te HVC mo te tatau pouara kia 60 ra (8 wiki), i te wa e tika ana ma runga rawa nga rama
Ngā wiki 14.
Täwariwari Tauritenga hoki HVC me etahi atu:
Ka whakawhiwhia e te kaiwhakaari o te HVC tetahi momo momo hangore, penei i te kaihoko GIS (Gas Insulated Switchgear), ratou
i te nuinga o te wa me iti ake te rahi o te potae teitei, ka whakaekea e maatau te potae-encapsulation kia tutuki pai ai te hiahia. Ahakoa
etahi atu kaihanga kaore e ngawari ki a maatau, ka tono ranei mo tetahi MOQ tino nui.
