Ihame shingiro

Ukoresheje imirongo ya LC na RL, capacitor C yashizwemo irekura imitwaro idafite umurongo unyuze muri inductance L hamwe na R irwanya R kubyara imbaraga zihuye nibisabwa bisanzwe.

The Basic Principle

Ibisobanuro nyamukuru

Imiterere ya none: 8 / 20μs
Ikigereranyo kigezweho: 10kA
Uburyo bwo Kwirengagiza: Pneumatic displacement isohora umupira intera.Igenzura ryikora, kugenzura intoki.
Ubuharike bwa none: bwiza.Iyerekana rya Waveform: ikigezweho-kibi;ibisigisigi bya voltage-nziza.
Ibipimo bigezweho: Igiceri cya Rogowski (0-50kA), ubunyangamugayo: 1%.
Ibipimo bya voltage bisigaye: kugabanya imbaraga za voltage igabanya (0-100kV), ubunyangamugayo: 1%
Muri rusange ibipimo byo gupima: 3%
Kwerekana Waveform: Oscilloscope (Tektronix) na PC.
Oscilloscope na capacitori yumuriro wa voltage yashyizwe kuri PC hamwe nurufunguzo rumwe.
Kubika amakuru: kuri PC.Ibipimo byo gupima hamwe na waveform byegeranijwe na oscilloscope, hanyuma bigahita byoherezwa kuri PC ukoresheje icyambu cya USB, hanyuma bikabikwa nka format ya Excel mububiko bwateganijwe kuri disiki ya mudasobwa.
Kurinda umutekano: birenze-voltage, birenze-bigezweho, guhuza kugenzura guhuza, guhagarara byihutirwa, guhagarara byikora.Bifite ibikoresho byo kumanura intoki: abakozi babakozi bagomba gusohora hamwe nubutaka mbere yo kuvugana numubiri wa generator, gusimbuza imashini itanga imbaraga, gusimbuza ikintu cyogupima, gusana, nibindi, hanyuma ugahuza umurongo wubutaka na HV kumpera yumubiri.
Kurwanya ubutaka: ≤1Ω
Amashanyarazi: 220V ± 10%, 50Hz;ubushobozi 10kVA

Ibyingenzi

Igice cyo kwishyuza
1) Uburyo bwo kwishyuza: igice cya kabiri cyo gukosora hamwe numuyoboro uhoraho mumuzunguruko wa LC kuruhande rwibanze.Uruhande rwibanze rufite imiyoboro ngufi / kurenza imitwaro.
2) Umuvuduko ukabije wa diode: reba voltage 150kV, Max.Impuzandengo ya 0.2A.
3) Transformer yibanze ya voltage 220V, voltage ya kabiri 50kV, ubushobozi bwa 10kVA.
)
5.
6) Gukurikirana ingufu za capacitori: DC irwanya voltage igabanya ibirahuri bya uranium hamwe nicyuma cya firime.Ikimenyetso cya voltage yikiganza gito cya voltage cyoherezwa muri sisitemu yo gupima ukoresheje umugozi ukingiwe.

Igice cyo gusohora
1.
)
3) Umwanya wo gusohora ugizwe na grafite hamwe nubushyuhe bukomeye hamwe no kurwanya umuyaga munini.
Impulse Current Generator3
Amashanyarazi
1) Imashini enye zibika ingufu zigabanijwemo amatsinda abiri hanyuma zigashyirwa kumurongo wa chassis.Induction ya Wave-imbere hamwe na resistance-end irwanya bikurikiranye mumwanya uhuye, byoroshye, bisobanutse, bihamye kandi byizewe.
2) Gufata igikoresho cyibizamini bikomezwa na pneumatic pusher.
3) Igikoresho cyo gutwika gikoresha pneumatike kugirango yimure intera yumupira yitaruye kandi isohoke binyuze mu cyuho cyumupira, gihamye kandi cyizewe.

Igikoresho cyo gupima

1) Umuvuduko usigaye: kugabanya imbaraga za voltage igabanya, kutarwanya inductive, precision high, Max.voltage ni 30kV, ifite 1pc 75Ω yo gupima umugozi, metero 5.
2) Ibiriho: Ukoresheje igiceri cya Rogowski hamwe numuyoboro ntarengwa wa 100kA na 1pc 75Ω wapima umugozi, metero 5.
3) Oscilloscope: Ukoresheje Tektronix DPO2002B, igipimo cyicyitegererezo cya 1GS / s, umurongo mugari wa 100MHz, imiyoboro ibiri.
4) Porogaramu: ifite ibikoresho bya ICG impulse ya sisitemu yo gupima, hamwe namakuru hamwe numurongo wo gusoma / kubika no kubara.
10kA Impulse Current Generator1Igice cyo kugenzura
1) Ubwoko bwimbonerahamwe Workbench ituma abakozi bakora bakora bicaye, byoroshye.
2) Inama y'Abaminisitiri ifite ibikoresho byimukanwa hamwe n’inkunga ihamye, ishobora koroshya kugenda no gutunganya imyanya.
3) Igishushanyo mbonera cyiza cya sisitemu yo kugenzura, imikoreshereze-yumukoresha-interineti, buto 3 gusa (kwishyuza, gusohora, gutwika) hamwe na bande ihinduranya (guhinduranya imirongo ine), kwizerwa cyane, imiterere yoroshye, byoroshye gukora, byoroshye kubungabunga.
4) Igenamiterere rya Oscilloscope rigenzurwa na mudasobwa kandi ryuzuzwa nurufunguzo rumwe, rwirinda imikorere yintoki (oscilloscope ifite imirimo myinshi, bigoye kubatari abanyamwuga kugenzura).
5) Capacitor yishyuza voltage igenzurwa na mudasobwa, hamwe ninteruro isobanutse nibikorwa byoroshye.
6) Oscilloscope ishyiraho itumanaho hamwe na mudasobwa, amakuru yo gupima hamwe na flimform ihita ibikwa muri mudasobwa, kandi inyandiko ya Excel ihita ikorwa.
7) Amashanyarazi yo kugenzura sisitemu: yitandukanije na transformateur na filteri.
8) Kurinda: hejuru ya voltage, kurenza-bigezweho, guhuza kugenzura guhuza, guhagarara byihutirwa, guhagarara byikora, nibindi.

Porogaramu yo gusesengura ibipimo

Porogaramu yisesengura yateguwe kugirango impulse igerageze irashobora guhita isoma imiterere yumurongo hamwe namakuru binyuze mu itumanaho na oscilloscope no gusuzuma imiterere ikurikije uburyo bwo gupima ibipimo bya IEC1083-2.Impinga ya none, voltage peak, umwanya-wimbere nigihe cyigihe-cyanyuma kibarwa mu buryo bwikora kandi bikerekanwa kuri ecran ya mudasobwa hamwe na test ya flake.

Ibyatanzwe na flake birashobora kubikwa mu buryo bwikora kandi bikomeza (kurasa ku buryo butemewe kurubuga)
