分析了直流电力机车主电路阻容吸收回路电阻过热烧损的原因,通过对阻容电路及电阻元件散热条件的改进,改善了高次谐波对直流电力机车的干扰,有效解决了电阻元件的烧损问题。
The reasons of overheating and burning resistance of the RC circuit of the main circuit of DC locomotive are analyzed. By improving the cooling conditions of the RC circuit and the resistance element, the interference of the higher harmonics to the DC locomotive is improved, and the effect of the resistance element Burning problem.
