NR-DP series ultra-low frequency high-voltage generator

Ultra-low frequency withstand voltage test is an alternative to power frequency withstand voltage test. For large-scale generators, cables and other samples with large capacitance, a large-capacity test transformer or resonant transformer is required for power frequency withstand voltage test, resulting in large equipment size and weight, which is extremely inconvenient for on-site use. Experiments have proved that using 0.1Hz ultra-low frequency withstand voltage test instead of power frequency withstand voltage test has the same equivalence, and the equipment is smaller and lighter, which is convenient for on-site use.

Product description

Product Introduction

　　Ultra-low frequency insulation withstand voltage test is a replacement for power frequency withstand voltage test. For large generators, cables and other test samples with large capacitance, a large-capacity test transformer or resonant transformer is required for power frequency withstand voltage test, resulting in large equipment size and weight, which is extremely inconvenient for on-site use. Experiments have proved that using 0.1Hz ultra-low frequency withstand voltage test instead of power frequency withstand voltage test has the same equivalence, and the equipment is smaller and lighter, which is convenient for on-site use.

Main Features

　　◆ Current, voltage, and waveform data are directly sampled from the high-voltage side, ensuring accurate data;

　　◆ It has overvoltage protection function. When the output exceeds the set limit voltage, the instrument will shut down for protection, and the action time is less than 20ms;

　　◆ It has overcurrent protection function, with high and low voltage double protection. The high-voltage side can be accurately shut down according to the set value; the low-voltage side will shut down when the current exceeds the rated current, and the action time is less than 20ms;

　　◆ The high-voltage output protection resistor is designed in the booster body, so no external protection resistor is needed;

　　◆ Due to the adoption of high and low voltage closed-loop negative feedback control circuit, the output has no overshoot effect.

Technical Parameters

　　◆ Output Voltage: 30kV/60kV/80kV

　　◆ Output Frequency: 0.1Hz/0.05Hz/0.02Hz

　　◆ Load Capacity: 0.1 Hz≤1.1μF/0.05Hz≤2.2μF/0.02Hz≤5.5μF

　　◆ Measurement Accuracy: 3%

　　◆ Positive and Negative Peak Value Error: ≤3%

　　◆ Waveform Distortion: ≤5%

　　◆ Power Supply: 0-220V 50 Hz

　　◆ Weight: Controller: 4kg Booster: 25kg
