The Basic Principle

Imininingwane Eyinhloko

Ifomethi yegagasi yamanje: 8/20μs
Ikalwe okwamanje: 10kA
Indlela yokubasa: Ibanga lebhola le-pneumatic displacement.Ukulawula okuzenzakalelayo, ukulawula okwenziwa ngesandla.
I-polarity yamanje: iphozithivu.Isibonisi se-Waveform: okwamanje-negative;i-residual voltage-positive.
Isilinganiso samanje: ikhoyili ye-Rogowski (0-50kA), ukunemba: 1%.
Isilinganiso se-voltage esalayo: isihlukanisi se-voltage ukumelana (0-100kV), ukunemba: 1%
Ukunemba kwesilinganiso sekukonke: 3%
Isibonisi se-Waveform: I-Oscilloscope (Tektronix) ne-PC.
I-voltage yokushaja ye-oscilloscope ne-capacitor isethwe ku-PC ngokhiye owodwa.
Ukugcinwa kwedatha: ku-PC.Idatha yokulinganisa ne-waveform iqoqwa nge-oscilloscope, futhi idluliselwe ngokuzenzakalelayo ku-PC ngembobo ye-USB, futhi igcinwe njengefomethi ye-Excel kufolda esethiwe ku-hard disk yekhompyutha.
Ukuvikela ukuphepha: i-over-voltage, over-current, control control link, isitobhi esiphuthumayo, ukuzinza okuzenzakalelayo.Ifakwe ibha yokuqinisa eyenziwe ngesandla: izisebenzi zokusebenza kufanele zikhiphe ibha yokubeka phansi ngaphambi kokuxhumana nomzimba okhiqiza ijeneretha, esikhundleni sokuphikisa i-waveform resistor, ukufaka esikhundleni sento yokuhlola, ukulungisa, njll., futhi baxhume ibha ephansi ekugcineni kwe-HV yomzimba.
Ukumelana nokuphansi: ≤1Ω
Ukunikezwa kwamandla: 220V±10%, 50Hz;amandla 10kVA

Izingxenye Eziyinhloko

Iyunithi yokushaja
I-1) Indlela yokushaja: ukulungiswa kwegagasi okuyingxenye okukhona okwamanje kumjikelezo we-LC ohlangothini oluyinhloko lwe-transformer.Uhlangothi oluyinhloko lunokuvikelwa komjikelezo omfushane/ukulayisha ngokweqile.
2) I-High-voltage rectifier diode: i-reverse voltage 150kV, Max.Isilinganiso samanje ngu-0.2A.
3) I-Transformer primary voltage 220V, i-voltage yesibili engu-50kV, amandla alinganiselwe angu-10kVA.
4) I-resistor yokushaja yokuvikela: intambo yokumelana ne-enameled iyinxeba eliminyene ngokucindezelayo kushubhu lokufakelwa.
5) Idivayisi eqhubekayo yokushaja: ngaphakathi kwe-voltage yokushaja elinganiselwe engu-10 ~ 100%, ukunemba okungalungiseka kwe-voltage yokushaja ngu-1%, nokunemba kwangempela kokushaja kungcono kuno-1%.
I-6) Ukuqapha i-voltage ye-capacitor: Isihlukanisi se-voltage ye-DC sisebenzisa ukumelana nengilazi ye-uranium kanye nokumelana nefilimu yensimbi.Isignali kagesi yengalo ye-low-voltage idluliselwa kusistimu yokulinganisa ngekhebula elivikelekile.

Iyunithi yokukhipha
1) Umshini wokuzibekela phansi ngokuzenzakalelayo: lapho ukuhlola kuyekwa noma esinye isizathu sibangela ukuthi isilawuli sokufinyelela sivuleke, itheminali yamandla kagesi aphezulu ingamiswa ngokuzenzakalelayo yi-resistor evikelayo futhi ikhishwe ngokushesha.
I-2) Idivayisi yokukhipha ithatha ukuhlukaniswa kwe-valve ye-solenoid ye-pneumatic kanye nendlela yokumisa phansi, enesakhiwo esihlangene, ukuzinza okunamandla kokudlulisela kanye nesenzo esithembekile.
I-3) I-discharge sphere yenziwe nge-graphite enokumelana nokushisa okuqinile nokumelana namandla amakhulu.

Ijeneretha
I-1) Ama-capacitor amane okugcina amandla ahlukaniswe ngamaqembu amabili futhi abekwe kubakaki be-chassis eboshiwe ngokulandelanayo.I-Wave-front inductance kanye nokumelana nokuphela kwegagasi kugxilwe ngokulandelana ezindaweni ezihambisanayo, ezilula, ezicacile, eziqinile futhi ezinokwethenjelwa.
2) Idivaysi yokugoqa into yokuhlola iqiniswa ipusher yomoya.
3) Idivayisi yokuthungela isebenzisa izingxenye ze-pneumatic ukuhambisa ibanga lebhola elingalodwa futhi likhiphe ngegebe lebhola, elizinzile futhi elithembekile.

Ithuluzi Lokukala

I-1) I-voltage eyinsalela: isihlukanisi se-voltage yokumelana, ukumelana okungeyona inductive, ukunemba okuphezulu, i-Max.I-voltage ingu-30kV, ifakwe ikhebula lokulinganisa elingu-1pc 75Ω, amamitha angu-5.
2) Okwamanje: Kusetshenziswa ikhoyili ye-Rogowski enamandla amakhulu amanje angu-100kA kanye nekhebula lokulinganisa elingu-1pc 75Ω, amamitha angu-5.
3) I-Oscilloscope: Isebenzisa i-Tektronix DPO2002B, izinga lesampula le-1GS/s, i-broadband engu-100MHz, iziteshi ezimbili.
4) Isofthiwe: ifakwe uhlelo lwamanje lokulinganisa lwe-ICG, olunedatha kanye ne-waveform yokufunda/isitoreji nemisebenzi yokubala.
10kA Impulse Current Generator1Iyunithi yokulawula
I-1) Uhlobo lwethebula i-Workbench ivumela abasebenzi ukuthi basebenze behlezi, kulula kakhulu.
I-2) Ikhabhinethi ifakwe ama-casters ahambayo kanye nokusekelwa okungaguquki, okungenza kube lula ukunyakaza nokulungisa isikhundla.
I-3) Idizayini efanelekile yesistimu yokulawula, isikhombimsebenzisi esisebenziseka kalula, izinkinobho ezi-3 kuphela (ukushaja, ukukhipha, ukuthungela) kanye ne-band switch (ukuguqulwa kwe-waveform ezine), ukuthembeka okuphezulu, isakhiwo esilula, kulula ukuyisebenzisa, kulula ukuyigcina.
4) Ukulungiselelwa kwe-Oscilloscope kulawulwa yikhompyutha futhi kugcwaliswe ngokhiye owodwa, ogwema ukusebenza okuyinkimbinkimbi (i-oscilloscope inemisebenzi eminingi, okunzima ukuyilawula okungewona ochwepheshe).
5) I-voltage yokushaja ye-Capacitor ilawulwa yikhompyutha, ene-interface ecacile nokusebenza okulula.
6) I-oscilloscope isungula ukuxhumana kwekhompuyutha, idatha yokulinganisa kanye ne-waveform kugcinwa ngokuzenzakalelayo kukhompyutha, futhi idokhumenti ye-Excel ikhiqizwa ngokuzenzakalelayo.
7) Ukunikezwa kwamandla kwesistimu yokulawula: ihlukaniswe yi-transformer nesihlungi.
8) Ukuvikelwa: i-over-voltage, over-current, control control linkage, stop stop, automatic grounding, njll.

Isoftware Yokuhlaziya Ukulinganisa

Isoftware yokuhlaziya yakhelwe ukuhlolwa kwamanje okugxilile ingafunda ngokuzenzakalelayo i-waveform nedatha ngokuxhumana ne-oscilloscope futhi ihlole i-waveform ngokuya ngendlela yokulinganisa ye-IEC1083-2 ejwayelekile.Ukuphakama kwamanje, ukuphakama kwe-voltage, isikhathi esingaphambili kwegagasi nesikhathi sokuphela kwegagasi kubalwa ngokuzenzakalelayo futhi kuboniswa esikrinini sekhompyutha kanye nefomu lokuhlola legagasi.

Idatha ne-waveform ingalondolozwa ngokuzenzakalelayo nangokuqhubekayo (ukudubula okungahleliwe endaweni yokuhlola)
