High-voltage hipot tester HZZGF

DC

The DC hipot tester adopts high-frequency pulse width modulation (PWM) technology to make closed adjustment with high voltage stability, small ripple factor, and fast reliable protection circuit. The wide temperature LCD screen adopts green back light, which enables clear display either in bright light or in darkness. High-pressure components use Dupont new filling material, making the product more stable and reliable. Products are widely used in electricity power supply departments, power transmission and transformation engineering company and preventive test of large industrial enterprises and scientific research institutes as regulated DC high voltage power supply. Main Functional Characteristics: - DC hipot tester adopts high frequency PWM technology for closed adjustment with high voltage stability, small ripple factor, and fast reliable protection circuit. The generator can endure direct discharge by devices of large capacitance. It is small and lightweight, convenient for field use. - Full range of linear smoothly adjusted voltage, with voltage regulation accuracy smaller than 0.1%; voltage measurement accuracy is 0.5%, resolution 0.1kV; Current measurement accuracy is 0.5%, minimum resolution: control box 1μA, shock resistance current 0.1μA. - The generator uses AC 220 V power supply (AC220V±10%, 50 Hz±1%), ripple factor less than 0.5%, suitable for all-weather site use. - High voltage multiplier uses Dupont materials for full solid encapsulation, overcoming inconvenience of air and oil filled equipment. Broad base and outer cylinder of light quality makes it stand steadily and more convenient for maintenance. - 75% MOA voltage switch button, simple and convenient testing arrester. - Over-voltage setting function displays the over-voltage value during regulation process; perfect protection against discharge of over-voltage, over-current and short circuit. Ideal for cable experiments. - Perfect break line and non-zero potential start protection function protects the operator and samples at any time. Shock-proof control box, concise, clear panel design and voice prompt for operation.

Do not hold or pull the wire. - For the safety of the discharging personnel, the discharging pole must be firm and reliable. When discharging, the lead should be tilted at the back end to avoid flashed discharge between the ground and the sample. - Avoid using the power main switch to turn off the high voltage directly; use the high voltage switch first when shutting down. - When raising high voltage, turn on the high voltage switch. After the test, turn off the switch first, then the power switch. - Pay attention to the power supply voltage. After the test, fully discharge the subject for 1 minute.
