摘要

针对2018年以来怀化铁路枢纽地区频繁发生接触网谐振过电压导致的电力机车高压电气设备阻容吸收装置烧损、避雷器炸损、变流器直流过电压等故障，文章对该枢纽地区的牵引供变电系统接触网环境，和谐型机车网侧变流器谐波电流成因及常见机车故障进行了理论分析和现场实测，提出了增设地面高次谐波滤波装置和机车变流器网压传感器滤波环节的谐波治理方案和机车防护措施，上述方案和措施实施后取得良好的谐振过电压抑制效果。

Abstract

Aiming at the accidents of high-voltage electrical equipment in electric locomotive such as burn out of resistance-capacity absorption device, explosion damage of arrester, DC over-voltage of converter led by overhead line resonant overvoltage happening with increasing frequency in Huaihua railway hub area since 2018, through theoretical analysis and field measurement of the contact network environment of the traction power supply and transformation system in the hub area, the causes of harmonic current of the converter on the side of the HX locomotive network and the common locomotive faults, the harmonic control scheme and locomotive protection measures of adding the ground high-order harmonic filtering device and the filtering link of the voltage sensor of the locomotive converter network were put forward. After the implementation of the above schemes and measures, a good effect of resonance overvoltage suppression is obtained.
