摘要
采用直升机开展５００ ｋＶ 输电线路巡视与检修，是满足超高压、大机组、长距离现代大电网安全稳定经济运行要求相配套的先进的维护与检修手段，可从根本上改变目前５００ ｋＶ 伊冯甲乙双回线途经大兴安岭山脉２００ ｋｍ 多的无人区、自然道路状况极差、气侯条件恶劣的线路巡视与事故抢修困难的局面。
Helicopter inspection and service of 500 kV transmission lines are an advanced maintenance and service means, which meets the requirements for safe, steady and economic operation of modern big power network with SHV, large-scale units and long distance and also reforms the hard aspect of line inspection and failure rush repairs of 500 kV Yi Feng A, B double-lircuit (over Daxinganling, mountains with rocky ways and minimum weather conditions).
