XHHV535-4Z
Its main application lies in conducting impulse discharge and withstand voltage tests when performing fault testing on low and high voltage cables. As a high-end mobile (trolley-type) experimental instrument, it combines a DC high-voltage power supply, energy storage capacitor, discharge ball device, automatic discharge device, and voltage grade switching device into a single integrated system. This equipment comprehensively resolves the limitations of conventional experimental devices regarding ease of use, portability, safety, and reliability.
Product Features:
Equipped with automatic overcurrent, overvoltage, and overheat protection functions;
Features DC withstand voltage and impulse discharge functions;
High-voltage pulse output is uniform and controllable;
Superb short-circuit protection function allows the high-voltage output to work even when directly short-circuited to ground;
High-voltage side voltage measurement is real-time and accurate;
Zero-start protection ensures greater safety and reliability;
Discharge time can be arbitrarily set within a suitable interval.

Instrument Usage Precautions and Common Faults
1. When setting the instrument's timing parameters: It is strictly prohibited to set the closing time to greater than 0.2S, and strictly prohibited to set the capacitor energy storage time (opening time) to less than 3S. Otherwise, there is a risk of burning out the boost power supply or discharge device.
2. When using this device, carefully read the instrument's instruction manual and understand the operating procedures, wiring methods, and precautions.
3. The instrument is a highly precise electronic device; non-professionals are prohibited from disassembling it. Handle with care during transportation and movement; rough handling or impact is strictly prohibited.
4. The instrument must be reliably grounded before boosting the voltage.
5. Ensure that the instrument is switched off and discharged before switching between DC withstand voltage and impulse discharge functions.
6. At any time during the test, if an abnormality occurs, press the "Stop" button or turn off the power switch to ensure safety.
