Zgf Automatic AC DC Dielectric Withstand Test Device High Voltage Generator

Brief IntroductionZGF series DC high-voltage generators use high-frequency voltage doubler circuits, apply advanced PWM high-frequency pulse width modulation technology, closed-loop adjustment, and use large voltage feedback to greatly improve voltage stability. Use high-performance IGBT devices and driving technology with excellent performance, and adopt special shielding, isolation and grounding measures according to the theory of electromagnetic compatibility. The DC high voltage generator has realized high quality, portable, and can withstand rated voltage discharge without damage. It has the characteristics of large output power and small volume, reliable overvoltage, overcurrent and zero-position closing protection functions, with a voltage switching function of 0.75 times. Mainly applicable to power sector, industrial and mining, metallurgy, iron and steel and other enterprise power departments to conduct DC withstand voltage test or DC leakage current test on high voltage electrical equipment such as zinc oxide arresters, power cables, transformers, circuit breakers and generators.Scope of Application1. Electrical conductivity test of valve arrester.2. DC voltage withstand test and leakage current measurement of power transformers.3. DC withstand voltage test and leakage current measurement of high-voltage cables (35-500kV and below).4. U1mA DC reference voltage test of zinc oxide lightning arrester and leakage current test at 0.75U1mA.Features1.The DC high voltage generator has a small ripple coefficient, stable and reliable voltage output, no noise, and good reliability2. With over-voltage, over-current, zero-voltage start-up and fault protection functions, the voltage protection value can be set and displayed intuitively3. Digital display of voltage and current, and readings when power is on, which is convenient for monitoring the output status4, with a voltage conversion of 0.75 times, convenient for testing zinc oxide lightning arresters  Compact product structure, small size, easy to carryParameterSpecifications200/2200/3200/5300/2300/3300/5300/5300/10400/2400/3400/5Rated voltage(kV)200200200300300300300300400400400Rated current(mA)235235510235Rated power(W)400600100060090015001500300080012002000Control box quality(kg)5.56.06.56.56.57.57.5    Pressure cylinder quality(kg)8.799111111.511.5    Double cylinder height(mm)9709709701250125012501250    Voltage accuracy±(1.0%Reading + 2 words)Current accuracy±(1.0%Reading + 2 words)Ripple coefficient≤0.5%Voltage stabilityWhen the power supply voltage changes by ±10%≤1%Overload capabilityNo-load voltage can exceed 10% of rated voltage for 10 minutesThe maximum charging current is 1.25 times the rated currentPower supplySingle phase communication 50Hz 220V±10%Way of workingIntermittent use: rated load 30 minutes1.1 times rated voltage usage: 10 minutesWay of workingtemperature:-10ºC~+40ºCRelative humidity: no more than 85% at room temperature of 25 ° C (no condensation)Altitude: below 1500 metersWith capacitive load capacityThe tested product has unlimited capacityCharged with 1.5 times rated currentStructural featuresElectrical insulation doublerAir insulation, no leakageOperating box featuresHigh-precision 0.75UDC1mA one-touch button (accuracy ≤1.0%), suitable for zinc oxide lightning arrester testOvervoltage protection using digital dial switch, at a glance    FAQ1.
