摘要
为降低输电线路跳闸率,结合某地区三年来高压输电线路跳闸率和运行故障实际情况,分析了引起高压输电线路运行故障和跳闸的原因,并提出了为保障输电线路安全运行应采取的有效措施。影响输电线路安全运行的主要故障因素有雷击、风偏放电、外力破坏等,应根据具体的输电线路运作规律提出针对性防治措施,提高线路运行安全可靠性。
To decrease transmission lines trip rate, combining with the trip rate and operation faults of high voltage transmission lines of cer- tain area in recent three years, this paper analyzed the causes for the trip and faults and proposed the effective measures to ensure the transmis- sion lines operate safely. The main fault factors affecting the safe operation of the transmission lines are lightning stroke, windage yaw discharge and external force destruction etc. According to the concrete transmission lines operational rule, this paper puts forward the effective prevention and cure measures to raise the safe reliability of transmission lines.
