Product Overview
HMCJ 300kV 15kJ impulse voltage generator yog ib yam khoom uas ua rau impulse voltage nthwv dej. Nws yog siv los ntsuas qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob tiv thaiv atmospheric overvoltages thiab hloov overvoltages. Lub tshuab hluav taws xob tuaj yeem tsim cov qauv hluav taws xob impulse voltage waveforms, truncated lightning impulse voltage waves, standard switching impulse voltage waveforms, and user-specified non-standard impulse voltages, including steep-front pulses.

Technical Parameter
1 Rated Chav Voltage ± 100kV
2 Tso zis Voltage Waveform
2.1 Nyob rau hauv qhov sib txawv ntsuas voltages thiab nrog ib tug load capacitance, nws muaj peev xwm tsim ib tug tag nrho -yoj 1.2/50μs xob laim impulse voltage.
2.2 Siv cov khoom siv ntau- pob clipping, hluav taws xob impulse voltage clipping nrog lub sij hawm clipping ntawm 2 mus rau 6 μs tuaj yeem tau, nrog tus qauv sib txawv ntawm lub sij hawm clipping dispersion tsis tshaj 150 nS.
3 Voltage Utilization Factor: Thaum nruab nrog qhov tsim nyog surge capacitors rau qhov sib txawv load capacitances, qhov kev siv qhov tseem ceeb rau kev tsim 1.2/50μs xob laim impulse voltage tsis tsawg dua 0.85.
4 Lub Sijhawm Ua Haujlwm: Kev ua haujlwm tsis tu ncua yog khaws cia nrog ib qho kev them nqi / tso tawm txhua ob feeb ntawm qhov voltages siab dua 2/3 ntawm qhov ntsuas hluav taws xob. Ntawm qhov hluav taws xob qis dua 2/3 ntawm qhov ntsuas hluav taws xob, kev ua haujlwm tas mus li yog tswj nrog ib qho kev them nqi / tawm mus ib feeb.
Cov kev ceev faj
1. Lub zog hluav taws xob hauv hluav taws xob yuav tsum ua kom tau raws li qhov yuav tsum tau muaj peev xwm siab tshaj plaws.
2. Tag nrho cov hauv av yuav tsum tau ua raws li qhov tseeb ib qho -point grounding.
3. Tag nrho cov nthwv dej- kho cov resistors yuav tsum tsis txhob poob, khob, lossis nce mus.
4. Insulating lub tog raj kheej txhawb nqa yuav tsum tsis txhob raug ntaus lossis khawb; capacitors yuav tsum tsis txhob cuam tshuam los ntawm cov khoom hnyav.
5. Transformers thiab capacitors yuav tsum tsis txhob siv thaum muaj roj tsawg.
6. Cov khoom siv tag nrho yuav tsum tsis txhob siv lossis khaws cia thaum huab cua kub hauv qab -25 degree.
7. Copper pob qhov chaw yuav tsum tsis muaj khawb los yog cuam tshuam cov cim.
8. Cov khoom siv yuav tsum tsis txhob siv rau hauv qhov chaw inclined.
9. Tag nrho cov kab ke yuav tsum tsis txhob raug dej khov, dej, daus, lossis pos huab. Cov khoom siv hauv tsev yuav tsum tsis txhob muab khaws cia lossis siv sab nraum zoov.
10. Tom qab kev sim, tus yuam sij tswj lub console yuav tsum raug tshem tawm thiab khaws cia los ntawm tus neeg xaiv. Cov cuab yeej no yuav tsum tau ua los ntawm cov neeg ua haujlwm tau tso cai nkaus xwb.
11. Ua ntej siv cov cuab yeej no, ua tib zoo nyeem phau ntawv no, tshwj xeeb tshaj yog ua raws li cov cai uas tau teev tseg hauv cov khoom 6 thiab 7.
