Description
The high-voltage pulse generator fully complies with DL/T846-2016 "General Technical Conditions for High Voltage Test Equipment" and DL/T474-2017 "Guidelines for the Implementation of Field Insulation Tests". It is mainly used for impact discharge during fault testing of cables with voltage levels of 35kV and below; it can also be used for DC withstand voltage tests of other electrical equipment.

This device integrates DC high-voltage source, energy storage capacitor, and discharge ball gap into one. This equipment completely replaces the traditional test transformer weighing hundreds of kilograms, operation box and pulse energy storage capacitor (generally a set of 5kVA transformer weighs more than 60 kg, and the control box more than 30 kilograms, and more than 20 kilograms of pulse energy storage capacitors).

The power supply adopts high-precision, high-stability special high-voltage electronic components and high-frequency high-voltage technology, which makes the whole machine simple in structure and ultra-light in weight. The pulse generator adopts humanized design and operation mode, which is safe and reliable. It really achieves the effect of not being damaged by impact, and it can also work normally when the high voltage is short-circuited to the ground. It is currently the lightest and most user-friendly portable DC impact high-voltage equipment. It is an ideal product for power cable fault detection.

Panel function description:

1. High voltage output (DC): When DC withstand voltage, connect the high voltage output line.
2. High voltage output (EMP): When impact discharge, connect the high voltage output line.
3. Safety ground: the ground of the instrument casing, to prevent the instrument casing from being electrified or personnel from getting an electric shock.
4. Time setting: set the discharge time interval.
5. Voltmeter: High voltage output voltage indication, used to display voltage value in real time.
6. Power outlet: instrument working power, AC 220V±10%/50Hz±1Hz.
7. Fuse socket: where the fuse of the AC 220V power supply system is installed.
8. Power switch: "Stage I" means to turn on the AC 220V power supply to supply power to the system;

"Gear 0" means turn off the AC 220V power supply to power the system.

    9. Over-current protection switch: When pressed, it means that the over-current protection function has started; when it is popped up, it means that the instrument has triggered the over-current protection.

     10. Start button/zero indicator light:

When the zero indicator light is on (yellow), it means that it is in the zero state, press the start button to start the high voltage output;
When the zero position indicator light is off, it means that it is not in the zero position state. After turning the voltage adjustment knob counterclockwise to the zero position, the zero position indicator light is on, and then press the start button to start the high voltage output.

  11. Stop button/high-voltage indicator light: When the test is completed or abnormality occurs, press this button to cut off the high-voltage output, the high-voltage indicator light is on, indicating that the high-voltage output has been started; the high-voltage indicator light is off, indicating that the high-voltage output has stopped.

   12. Voltage adjustment knob: used to adjust the voltage; adjust the output high voltage clockwise to increase from small to large, and adjust the output high voltage counterclockwise to decrease from large to small.

   13. Discharge button: When the high voltage is stopped, press this button to manually discharge the internal storage power.

   14. Ammeter: Indicates the magnitude of the low-voltage measurement current.

  15. Sampling place: The negative terminal of the pulse energy storage capacitor has a high voltage and must be reliably grounded. It is used for sampling when the waveform is sampled in the high-voltage flashover state of the cable fault tester. (Sampling without high-voltage flashover still requires reliable grounding).

     16. High-voltage ground: also known as high-voltage tail, the internal devices of the instrument are grounded.


In the latest version of the device, we have added the DC withstand voltage connection channel and added the overcurrent protection button. The equipment is safer to use, the equipment self-protection system is more perfect, and the DC voltage resistance function is more clear.
