The high-voltage pulse generator fully meets the requirements of 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 impulse discharge and withstand voltage tests during low and high voltage cable fault tests. This device integrates a DC high voltage source, energy storage capacitor, discharge ball device, automatic discharge device, and voltage level switching device into a cart-type high-end experimental instrument. This equipment completely solves the problems of ease of use, portability, safety and reliability of traditional experimental devices. This instrument uses high-precision, high-stability dedicated high-voltage electronic components and high-frequency high-voltage technology to make its overall structure simple. In order to retain people's original habit of using transformers and operating boxes to generate DC high voltage, this pulse generator adopts a humanized design operation mode and integrates a micro-reliable circuit design. It is safe, reliable, and visually intuitive. It truly achieves the effect of being indestructible by impact, and also has automatic timing impact, manual impact and withstand voltage functions. It is currently the most humane cart-type DC impact high-voltage equipment in China. It is an ideal product for power cable fault detection.
