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.
