摘要
揭东电力局10kV军民双回输电线路(LGJ-240)在台风"珍珠"的袭击下,5根直线电杆连续倒杆,严重影响了电网的安全经济运行。为此,对电杆进行了受力分析,提出普通J级15m电杆不能满足风速为30m/s的使用工况的技术要求,指出原设计存在的问题,对今后10k V配电网输电线路的设计提出了一些建议,可供相关技术人员参考和借鉴。
Five straight-line wire poles on a 10 kV army-civilian double-circuit transmission line（LGJ-240）of J iedong Electric Power Bureau continuously fell under the attack of Typhoon Chanchu, seriously impacting the safe and economic operation of power grid, Upon stress analysis of the wire poles, it is indicated that common J-grade 15 m wire poles can not meet the technical requirements for use in a 30 m/s wind. The problems in the original design are pointed out, and some proposals for the design of 10 kV transmission lines in the future are put forward, thereby providing reference for relevant technical personnel.
