High-voltage withstand voltage test of electrical equipment is one of the most important itemsstipulated in"Insulation Preventive Test",and the withstand voltage test can be divided into ACwithstand voltage test and DC withstand voltage test,and the AC withstand voltage test can bedivided into industrial frequency,variable frequency and 0.1Hz ultra-low frequency test technology,of which 0.1Hz ultra-low frequency technology is the latest technology,which is the currenttechnology recommended by the International Electrotechnical Commission.
My company's new generation of series of ultra-low-frequency high-voltage generator is theuse of the latest technology developed independently of the core products,the use of 7-inch touchscreen,imported high-speed AD acquisition circuitry,as wellas advanced production processes.Improve the quality and stability of the instrument,reduce the volume and weight of the equipment,easy to operate,the cost-effective far higher than similar imported products mechanical booster short life,high failure rate,the short comings of the large volume.
1. High degree of intelligence:adopting digital frequencyconversiontechnology,microcomputer control,boosting,bucking,measuring and other test processes are fully automated.
2. Convenient operation:simple wiring,7-inch large LCD touchscreen,easy to operate,friendly human-machine interaction.
3. Comprehensive protection:multiple protection(over-voltageprotection,high and low voltage side over-current protection),rapid action(action time≤10ms),the instrument is safe and reliable.
4. Safe and reliable:controller and high voltage generator low voltage connection,photoelectric control,the use of safe and reliable.
5. High and low voltage closed-loop negative feedback control circuit is adopted,and the outputhas no capacitance rise effect.
6. Accurate sampling:High-voltage current and voltage data are obtained directly through thehigh-voltage side sampling,sothe data are real and accurate.
7. Complete configuration:7-inch capacitive touch screen,LCD English character display,automatic storage,automatic printing.
8. Wide test range:0.1Hz,0.05Hz and 0.02Hz with multiple frequency options,large test range.
9. Easy to carry:the instrument is small in size and light in weight,which is very favorable foroutdoor work.
