基于1000kV变压器的雷电冲击电压发生器设计

Design of lightning impulse voltage generator based on 1000kV transformer

以辽宁省重大专项"特高压1000k V发电机升压变压器"课题为背景,围绕雷电冲击电压试验的核心装置—多级冲击电压发生器,展开一系列设计。包括发生器输出电压、电容量、回路级数等核心参数设计,脉冲电容、波头波尾电阻、变压器、高压硅堆、球隙的设计与选型,并完成仿真验证。研究结果为"特高压1000k V发电机升压变压器"项目的试验技术研究提供一定的参考和借鉴作用。

This paper take Liaoning province major former＂ subject to the background, around the core stage impulse voltage generator, carried out a series projects ＂ UHV 1000kV generator step-up trans- equipment of lightning impulse voltage test- multi- of designs. Including designs of the generator out- put voltage, capacitance, circuit series and other core parameters, designs and selections of pulse ca- pacitors, wave head and wave tail resistors, transformers, high voltage silicon stack, ball-gap, and complete the simulation. Research results provide some reference and learning for experimental re- search of ＂UHV 1000kV generator step-up transformer＂ project.
