关于直流型电力机车过压吸收电阻烧损的分析

Analysis on the Absorption Resistance Loss of Traction Electric Locomotive DC Voltage Loop

通过和谐型电力机车在逆变过程中高次谐波对电网供电品质产生的影响,指出直流型电力机车牵引回路过电压吸收电阻大范围烧损是最具代表性的质量故障之一,并以SS4改电力机车为例进行分析,给出相应解决方案。

This paper summarizes the influence of the high harmonics of the harmonic electric locomotive during the process of the inverter, and the power supply quality of the power grid is generated. It points out that the DC electric locomotive traction circuit overvoltage absorption resistance to a wide range of burning is one of the most representative quality fault,take SS4 modified electric locomotive as an example for analysis and gives the corresponding solutions.
