XHHV535-4Z High Voltage Pulse Generator

Product Overview The XHHV535-4Z High Voltage Pulse Generator strictly complies with DL/T846-2016 General Technical Conditions for High Voltage Testing Equipment and DL/T474-2017 Implementation Guidelines for On-Site Insulation Tests. It is primarily used for impulse discharge testing of cable faults at 35kV and below, and also applicable to DC withstand voltage tests of other electrical equipment. Integrating a DC high-voltage source, energy storage capacitor, and discharge gap into one unit, this device completely replaces traditional bulky combinations of test transformers, control boxes, and pulse energy storage capacitors (a single set of traditional equipment exceeds 100kg). By adopting high-precision, high-stability dedicated high-voltage components and high-frequency high-voltage technology, it achieves a compact structure and ultra-light weight. With a humanized design ensuring safe operation, it features "impact resistance" and "normal operation under high-voltage short circuit," making it currently the lightest, most user-friendly portable DC impulse high-voltage equipment—an ideal choice for power cable fault detection.

Product Features
★ Equipped with automatic overcurrent, overvoltage, and overheating protection functions;
★ Features both DC withstand voltage and impulse discharge capabilities;
★ High-voltage pulse output is uniform and controllable;
★ Ultra-strong short-circuit protection function, enabling the high-voltage output to operate with direct grounding short circuit;
★ Dual 1.5-level pointer meters for current and voltage display, providing intuitive and clear readings—clearly indicating whether the fault point is fully discharged and reflecting the discharge process in real time;
★ High-voltage side voltage measurement, ensuring real-time precision;
★ Zero-position start protection for safer and more reliable operation;
★ Unique high-voltage measurement design: in the stopped state, the voltmeter can indicate the capacitor voltage value in real time, allowing operators to have full visibility of the high-voltage status;
★ Discharge time can be arbitrarily set within an appropriate interval.
