Xzh Test Xhdp Series Vlf Ultra-Low Frequency High Voltage Generator

This XHDP Series VLF AC cable hipot tester adopts digital frequency conversion technology, single-chip microcomputer control,voltage boost, buck, measurement, protection completely automatic. Due to the full electronic, so small size and light weight, the use of large screen color touch display, clear and intuitive, simple operation, display output waveform. The design index conforms to the national standard of "General Technical Conditions of Ultra-low frequency high voltage generator". The main features are as follows:

Technical parameter

1.Ultra-low frequency with rated voltage ≤60kV adopts a single-unit structure (one booster); ultra-low frequency above 60kV adopts a series structure (two boosters in series), which greatly reduces the overall weight and enhances the load capacity. The two boosters can be used separately to achieve multiple uses of one machine.

2.Current and voltage data are directly sampled from the high-voltage side, and the data is accurate.

3.Intelligent comprehensive protection function: There is no need to set the current and voltage protection values. The instrument calculates the overvoltage and overcurrent protection values according to the test capacity and test voltage value, and can protect against voltage and current mutations, so as to capture the discharge situation in time. The protection action time is less than 20ms.

4.150kV high-voltage incoming line output, safe and reliable.

5. Due to the use of closed-loop negative feedback control circuit, there is no capacity increase effect on the output.

Main structure of ultra-low frequency high voltage power supply(VLF hipot tester)

For the VLF hipot tester with a rated voltage below 50kv, a booster is used, which is called the single-coupled ultra-low frequency, and its structure and components are described in the following figure:

For VLF hipot tester with rated voltage above 50kv, two boosters are used in series, which is called series ultra-low frequency, and its structure and components are described in the following figure:
