2. XHHV535-4TSC Trolley High Voltage Surge Generator(with ARM multi-pulse filter built in)

Description
The XHHV535-4TSC  high voltage surge generator can be used impulse discharge and withstand voltage test in low and high voltage cable fault test. High-precision test cable fault sampling waveform module and small transformer are installed inside, which can truly achieve the effect of not being damaged by impact, and it also has the functions of automatic timing impact, manual impact and withstand voltage test.

This device integrates a high-voltage DC source, an energy storage capacitor, a discharge ball device, an automatic discharge device, and a voltage level switching device into a cart-type high-end experimental instrument. It is a trolley-type high-end experimental instrument. The equipment completely solves the problems of ease of use, portability, safety and reliability of traditional experimental devices.

When the XHHV535-4TSC trolley-type high-voltage surge generator is in use, after selecting the function switch, press the start button to perform high-voltage boosting work. After use, press the stop button, and the internal system will automatically release the remaining high voltage on the accumulator.

 

The high voltage pulse generator also has the function of zero-start protection, which can make the operation of the device more safe and reliable. It has super short-circuit protection function, which can make the high-voltage output work directly to the ground. With three-gear voltage range and capacitance capacity switching function, users can choose different equipment voltage adaption gears according to different cable voltage needs, making the test process easier.
