XHHV535-4T
This device is primarily designed for impulse discharge and withstand voltage tests during the fault detection of low and high-voltage cables. As a high-end cart-mounted test instrument, it integrates a DC high-voltage power supply, energy storage capacitors, discharge sphere assembly, automatic discharge unit, and a sampling module for cable fault testers into a single system. It fully addresses the drawbacks of traditional test setups, including inconvenience in operation, poor portability, and insufficient safety and reliability.
Adopting high-precision, high-stability specialized high-voltage electronic components and high-frequency high-voltage technology, the instrument features a simplified overall structure. To align with users’ conventional habits of generating DC high voltage via transformers and operation cabinets, this pulse generator is equipped with a user-friendly operation mode and integrated compact, reliable circuit design. It boasts advantages such as safe and reliable performance and intuitive visual monitoring, and achieves the genuine effect of being damage-proof against impulse impacts. Additionally, it is furnished with functions of automatic timed impulse, manual impulse, and withstand voltage testing.
Recognized as the most user-friendly cart-mounted DC impulse high-voltage equipment available domestically, it serves as an ideal solution for power cable fault detection.
