Te rereketanga i waenganui i te HVC me etahi atu Kaituku Nui Nui.

kounga; ko te koroni ka tino hiahia me te nuinga o te raruraru e nga hoa hou!
I muri e whakamārama matua mō ngā tawhā hangarau faufaa:

Mātao Āteteranei IR rite te ingoa e tohu ko te resistance otheinsulation.IR pono
tiaki i nga taputapu hiko mai i te raupapa porowhita poto.IR he tino nui rawa te mahi a Mega-ohm me Mohm.

Temperature Tauwhakareae whakawhirinaki ana ki te kohikohinga o te hangarau XIUMXorClass 1. He waa
Ko te kaitoha (ina koa te kapa 2) he maha nga waahanga tiketike, he nui te whakawhitinga tere o te whakawhitiwhiti.

Tauwehenga motumotu (tan δ): ko te DF kua tautuhia hei tauwehenga o te ESR me te reactive capacitive.It ko te
Ko te take o te whakakorenga ko te alsoknown hei painga o te koki o te utu, a, e whakaaturia ana i roto i te pauna.
Ko nga paerewa mohio e whakaatu ana i te take whakakore i te 120Hz frequenciestypically motuhake mo te Aluminium
kohikohikohikohiko electrolytic me te Tantalum i te mea ko nga kaitohu kiriata ko 1 kHzand 1 MHz mo nga kaitohu ira.

Whakaweto Ngati (PD): he hiko hiko, he wera ranei e hono ana i tetahi wahi iti o te hiku
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).

Material uruhanga:

Hei tauira, ka mahi te kaitao Z5U mai i +10 ° C ki te +85 ° C me te huringa o te kaha + 22% ki te -56%. Ka whakahaerehia he kaitaahiko X7R mai i -55 ° C ki te +125 ° C me te rereketanga o te kaha o te nuinga o te ± 15%. Nga Mea Hiko N4700 a te HVC: he rite ki etahi atu kamupene, ka whakaputahia e te hiko te waahanga nui o nga potae. Te whakapau a te HVC i nga tau e 3 me nga miriona taara ki te tarai i te strontium titanate, he momo N4700. Ko tenei rauemi N4700 he waahanga tino pai rawa atu, he tino pai te aukatinga me te waahanga iti me te roa o te ora ki te 20 tau.

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 *****
Ko nga potae kopae uku anake ta ratau e tuku ana, he rite ano ki nga taonga hiko a te HVC X5F.
Ko te whakakoretanga mo te X5F ko 1.5%;
Ka taea e te HVC X5F te whakahirahira Utaitai Whakamutu 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 ******:
He kaihaoha anake te kaapene.
10Kv max te puritanga 8000pf, i HVC kia taua 8000pf, taua rauemi momo N4700;
20kv max te puritanga 4000pf, i taea HVC e 10000pf;

G ******: Whakamahia te rauemi N4700, Ko te Pouaka Whakamuri kia 0.3% max, i te wa e noho tonu ana te HVC ki te 0.1%, kaore hoki i teitei
atu i 0.2%
G ******: Ko te 10,000mOhm (N4700) minita, ko te waitohu o te wairangi, ko te HVC te nuinga o te wa e taea te 200,000mOhm (N4700) min.

American Popular Brand H **:
Ko te utu anake ko te pana o te pene, ko te whakamahinga i te maketi o Amerika-a-Amerikiana.

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 American Brand H ***:
I hokona e ratou i NorthAmerica, Rusia, Hapani.
Mo te puranga kōpae waehu, anake Y5P, Y5U mate rauemi, e kore e whakaekea he pai te kounga o te pāmahana, ahakoa
HVC tuku N4700 mō potae kōpae uku.

Ko te kaha teitei o te kahahiko, H *** whakaatu ko 20KV 4700pf (Y5U), ka tukuhia 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)

European M Mii *****:
Kamupene rongonui o te ao, whakarato i te capacitorno capacitorin momo rerekē, rauemi matatini i roto i te taumata Y5U me te N4700.
Ko te hua o tenei ingoa nui he tino awangawanga ki te utu whakaheke i te waahanga, ko a raatau taonga ka tino iti te pc ina oti te whakatau
AC voltage, Ahakoa e whakaekea ana e te HVC te taumata o te kounga iti o te iti.
Whiwhi Whiwhi Whiwhi beN4700 me te aukaha Rawa> = 1011ohm, Ahakoa ko nga mea a te HVC ake N4700 kia rua, min 2x1011ohm

Te ao rongonui a te Hapanihi T **:
Ko tenei kaiwhakanao ko te kaihanga o te komihana o te akomanga ao, me te nui o te mahi hanga
whakatipu i roto i te ao, kei te whakaputa hoki i te tomuku patupuku, me te waihanga i o raatau ake rauemi matai taonga
hei Z5T, Y5P me Y5S, ko era anake ko nga whakarea o te pāmahana soso, kaore o raatau taumata N4700material, e
whakaekea te taumaha teitei me te kaha o te kaha mate-mate. Ko etahi atu MA5S ko etahi momo rauemi ehara i te PB noa.
Engari kia ea ki teRoHS “Aronga EU2002 / 95 / EC, mata, cadmium, mercury, hexavalent chromium, me te motuhake
ko nga retardants mura o te bromine, PBB me PBDE, kaore i whakamahia, haunga ia mo nga tono kua whakakahoretia ”forhigh
tono ngaohiko, kaua e hiahiatia kia kore e arataki. Engari kaore e kore e taea e te kaihokohoko nui te arahi i te kaihoko koreutu. Rahi
Ko te whakahekenga voltage anake 50kv 2100pf, engari ka taea e 20kvAC 1080p te tiro, tenei 20kvAC ka rite tonu ki te 80kvDC.
Ahakoa ka taea e te HVC te hanga 150kvDc (50kvAC), te mea 800pf, he kaha teitei o te HVC mo te mutunga o te mutunga
tono. Te Whakatoatanga Whakaoho 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 tetahi o nga ahuatanga kounga o te ao rongonui
Vishay, TDK, Murata, Morganetc… Ana kei te 20% ki te 30% te utu iti ake mo te nuinga.

Leadtime Tauritenga hoki HVC me etahi atu:
Ko te wa haahi a te HVC mo te mahi whakatuu tatau kia 60 ra (8 wiki), me te 14 wiki te roa o nga waitohu
Täwariwari Tauritenga hoki HVC me etahi atu:
Ka whakawhiwhia e te kaiwhakaari o te HVC tetahi momo momo hangore, penei i te kaihoko GIS (GasInsulated Switchgear), he iti ake te hiahia
te rahi o te potae teitei, te potae o te potae-kapekepeke ki te whakatutuki i te piripiri. Ahakoa kaore he kaiwhakarato rereke, ka tono ranei mo te MOQ nui.
