变电站双回线路单回检修时的危险性分析

Hazard Analysis of Single Circuit Line in Maintenance for Double Circuit Transmission Line of Substation

由于大容量输电的需要,双回线路在国内广泛采用。主要针对双回线路一回运行,另一回检修的状况,通过对运行线路正常状态和故障状态下检修线路的感应电压电流的计算,分析此情况下检修的危险性并提出安全检修的注意事项。

Double circuit transmission line is widely adopted in China owing to the demand of large - capacity power transmission. When one hne is in operation and another is in maintenance, induced voltage and current of overhauled line are calculated under the nomad conditions and fault conditions of nmning line. As a result, the hazard is analyzed and the matters needing attention for safety maintenance are proposed.
