Technical Characteristics and Application Research of Modular Surge Voltage Test Generator

Abstract:

Introduction

With the rapid development of power, communication, industrial control, new energy and other industries, the operating environment of electrical and electronic equipment is becoming increasingly complex. Interferences such as lightning surges, switching transients, and load switching shocks occur frequently, which can easily cause equipment crashes, data damage, and even permanent breakdown of components. To ensure the stable operation of equipment in complex electromagnetic environments, various countries have formulated strict surge immunity test standards, and the surge voltage test generator is the core equipment for carrying out such tests.

Traditional surge voltage test generators mostly adopt a fixed structure with single output level and fixed waveform configuration. In addition, external oscilloscopes, high-voltage probes and other auxiliary equipment are required to complete waveform observation, which not only has complicated wiring and cumbersome operation, but also easily introduces errors due to connection links, affecting the accuracy of test results. The LISUN SG61000-5 surge voltage test generator features an innovative design targeting the above pain points. It adopts a highly modular architecture, realizing wide-range voltage and current output, multi-standard waveform compatibility and integrated detection system, reaching the advanced industry level in usability, accuracy and scalability.

Modular Design and Output Capability of the Surge Voltage Test Generator

Characteristics of Modular Architecture

The LISUN SG61000-5 surge voltage test generator adopts a separated modular design including high-voltage module, waveform generation module, coupling-decoupling module, control module and detection module. Each module has independent functions and standardized interfaces, which can be flexibly combined, expanded or upgraded according to test requirements. It not only meets the test requirements of products at different levels, but also facilitates later maintenance and fault location. The modular design enables this surge voltage test generator to cover full-scenario tests from low-voltage household appliances to high-voltage power equipment, greatly improving the versatility of the equipment.

Wide-Range Voltage and Current Output

Relying on modular high-voltage and current units, the LISUN SG61000-5 surge voltage test generator achieves an extremely wide output range: voltage output covers 0~30kV, current output reaches up to 0~15kA, and the output accuracy is controlled within ±5%. Whether it is low-level testing for low-power power supplies and household appliances, or high-level equipment testing such as charging piles, inverters and industrial controllers, it can be easily realized through module configuration without replacing multiple devices, significantly reducing laboratory investment costs.

Standard Surge Waveform Output

This surge voltage test generator strictly complies with IEC 61000-4-5, GB/T 17626.5 and other standards, and can stably output four core types of waveforms: open-circuit voltage waveforms include 1.2/50μs combination wave and 10/700μs telecommunication line waveform; short-circuit current waveforms include 8/20μs combination wave and 5/320μs special waveform for telecommunication lines. The errors of rise time and half-peak time of all waveforms are controlled within ±20%, ensuring reproducible and comparable test results that fully meet the requirements of certification laboratories.

Integrated Detection and Intelligent Operation Design

One of the biggest highlights of the LISUN SG61000-5 surge voltage test generator is the integration of the detection system. The equipment is equipped with dedicated built-in voltage and current attenuator probes and a high-speed electronic oscilloscope module. High-voltage signals are directly collected and processed after internal attenuation, without external oscilloscopes, high-voltage probes and extension cables. Operators can directly view real-time output waveforms through the LCD touch screen, intuitively judging key parameters such as peak value, rise time and half-width, avoiding connection errors and waveform distortion caused by external equipment.

At the same time, this surge voltage test generator adopts an intelligent touch control operating system, supporting automatic positive/negative polarity switching, surge count setting, phase synchronization control, fast adjustment of output gears and other functions, with a simple and intuitive operation interface. The built-in self-test and protection mechanism can monitor the module status in real time, automatically alarm and cut off the output in case of abnormalities, ensuring the safety of operators and equipment under test. The overall design greatly simplifies the test process and improves test efficiency and parameter accuracy.
