摘要
分析了电力机车过关节式电分相的全过程,研究造成关节式电分相过电压的原因、产生机理,并结合现场实测数据,探讨了治理过电压的方法,设计出自控式阻容吸收过电压抑制装置。结果表明,该装置可以有效地抑制机车过关节式电分相时产生的过电压。
Through the analysis of the whole process of electric locomotive passing the articulated phase insulator, the causes and mechanism of generating over-voltages in the Articulated Phase Insulator are analyzed. Combining with the measured data, this paper discusses the management method of inhibiting overvoltage, and designes the self-controlled RC protector to inhibit over-voltage. The results show that the device can effectively suppress Over-voltages of Locomotive Passing the Articulated Phase Insulator.
