XHHV535-4 High-Voltage Pulse Generator

Product Overview The high-voltage pulse generator complies with DL/T846-2016 General Technical Conditions for High Voltage Testing Equipment and DL/T474-2017 Implementation Guidelines for On-site Insulation Tests, primarily used for impulse discharge during cable fault testing. This device integrates a DC high-voltage source, energy storage capacitor, and discharge sphere gap into one unit, replacing traditional bulky test transformers, control boxes, and pulse energy storage capacitors (a single set of traditional equipment weighs over 100kg). Adopting high-precision, high-stability dedicated high-voltage electronic components and high-frequency high-voltage technology, the entire unit features a simple structure and ultra-light weight. It retains the operation habits of traditional transformers/control boxes, with a humanized design that ensures safety and reliability. It boasts impact-resistant and indestructible characteristics, remaining fully operational even under high-voltage ground short-circuit conditions. Currently the lightest, most humanized portable DC impulse high-voltage equipment, it serves as an ideal product for power cable fault detection.
