摘要
分析了关节式电分相承力索烧损的主要原因,提出了防止烧损承力索的解决方案,包括安装车载断电自动过分相装置、RC保护装置、避雷器、保护条与电连接线,重视关节式电分相参数的检调,加强关节式电分相巡视。运行情况表明安装车载断电自动转换分相装置能有效防止关节式电分相承力索烧损,仿真结果表明安装RC保护装置可以有效抑制过电压。
The paper analyzes the major causes of burning out of messenger wire at articulated neutral section, puts forward the resolution scheme for prevention of burning out of messenger wire by installation of on-board device for power off automatic passing through neutral section, RC protection device, lightning arrestor, protection strip and electric connection wire, paying attentions to inspection and calibration of articulated neutral section parameters and strengthening patrol on articulated neutral section. The simulation results show that installation of RC protection device is able to control the overvoltage effectively.
