HZ-535-4 4UF 2550j 35kV DC High Voltage Pulse Generator

Product Description

I.Overview

The high-voltage pulse generator fully meets DL/T846-2016 "The UMC Technology Conditions of High-voltage Test Equipment" and DL/T474-2017 "Director of Implementation of on-site Insulation Test Implementation". It is mainly used for impact discharge during cable failure testing. This device integrates DC high -voltage sources, energy storage capacitors, and discharge balls.

II.Product Features

The high-voltage generator is equipped with a comprehensive range of features designed to ensure safe, reliable, and precise operation across a variety of testing applications.

Automatic Protection – Overcurrent, overvoltage, and overheating protection functions are automatically activated, safeguarding both the instrument and the device under test.

Uniform High-Voltage Pulse Output – The high-voltage pulse output is both uniform and fully controllable, ensuring consistent and repeatable test results.

Super Short-Circuit Protection – A robust short-circuit protection feature allows the high-voltage output to be directly shorted to ground without causing damage to the instrument.

Dual Pointer Meter Display – Both current and voltage are displayed on high-quality 1.5-class pointer meters. The intuitive, bright display provides clear visibility of the impact discharge process at a glance.

Real-Time Voltage Measurement – Voltage is measured directly on the high-voltage side, delivering accurate, real-time readings.

Zero-Start Protection – The instrument features zero-start protection, with an automatic potentiometer return-to-zero output function, ensuring safe and reliable startup every time.

Unique High-Voltage Measurement Design – Even when the system is in the stopped state, the voltmeter continues to display the capacitor voltage in real time, providing valuable diagnostic information.

Emergency Stop Function – In emergency situations, the emergency stop function immediately cuts off the high-voltage output, ensuring operator safety.

IV.Working Principles

The high -voltage pulse generator is a system used to occur to a DC high -voltage pulse signal, which generates the electrical test signal of the required parameters. It is often used as the impact high -voltage power supply for the 35kV voltage level and the power cable failure detection below.

It is composed of charging circuit and discharge circuit. The voltage of high -voltage cables is sampled and sent to the voltage voltage control circuit. The impact of the magnetic combination of DC high -voltage power, energy storage capacitance, and high -voltage discharge ball gap. Use fault testing and acoustic synchronous fault point. The working principle is shown in the figure below:
