Product Description Product introduction The high-voltage withstand test of electrical equipment is one of the most important items stipulated in the "Insulation Preventive Test". The withstand voltage test can be divided into AC withstand voltage test and DC withstand voltage test, and AC withstand voltage test can be divided into power frequency, frequency conversion and 0.1Hz ultra-low frequency test technology. Committee-recommended technique. Our company's new generation of this series of ultra-low frequency high-voltage generators is a core product independently developed by the latest American technology. It adopts a 7-inch touch screen, the latest ARM7 single-chip microcomputer, high-speed AD acquisition circuit, and is equipped with background management software. It overcomes many shortcomings of similar domestic products (see Table 1), and its cost performance is much higher than that of similar imported products. It is especially suitable for electrical equipment with large insulation equivalent capacitance (such as power cables, power capacitors, large and medium-sized generators and Electric motors, etc.) withstand voltage test, in line with the requirements of the newly promulgated power industry standard "General Technical Conditions for Ultra-low Frequency High Voltage Generators DL/T849.4-2004" in 2004.Table 2 performance comparison of various withstand voltage test equipment: Compare contentPower frequency withstand voltageFrequency withstandvoltage0.1Hz withstand voltageDC withstand voltageEquivalencegoodGoodGoodBadInsulationdestructivesmallsmallsmallbigOperation safetylowlowhighA little lowWiringComplicatedMostComplicatedMost easycomplicatedVolume andweightHeavy and bigHeavy and bigLight and smallsizeLight and smallsizeProduct Features1. Advanced technology: using digital frequency conversion technology, microcomputer control, fully automated test processes such as boosting, bucking, measurement, and protection.2. Convenient operation: simple wiring, fool-like operation.3. Comprehensive protection: multiple protections (overvoltage protection, high and low voltage side overcurrent protection), rapid action (action time ≤ 10ms), and the instrument is safe and reliable.4. Safe and reliable: low-voltage connection between the controller and the high-voltage generator, photoelectric control, safe and reliable use.5. The high and low voltage closed-loop negative feedback control circuit is adopted, and the output has no capacity rise effect.6. Complete configuration: capacitive touch screen, LCD English character display, automatic storage, automatic printing.7. Large test range: 0.1Hz, 0.05Hz and 0.02Hz multi-frequency selection, large test range.8. Small size and light weight: it is very beneficial to outdoor work.9.
