基于X光探伤在超特高压输电线路“三跨”耐张线夹应用的差异化运维管理研究

Research on Differential O&M Management Based on X-ray Inspection in Three-span Strain Clamp Application in Super UHV Transmission Lines

架空输电线路耐张线夹压接质量不合格,容易发生掉线,特别会给超特高压输电线路"三跨"(跨越高速铁路、高速公路和重要输电通道区段)运维的安全造成重大危险。因此,基于所辖线路"三跨"X光无损探伤结果,进行统计分析,提出差异化运维管理的针对性措施,确保架空输电线路"三跨"安全稳定运行。

The crimping quality of strain-resistant clamps on overhead transmission lines is unqualified and is easily dropped. In particular, the safety and operation of the＂three-span＂transmission lines（over high-speed railways,expressways, and important transmission passage sections） for ultra-high voltage transmission lines cause a major danger. Therefore, based on the＂ three-span ＂X-ray non-destructive inspection results of the circuits under its jurisdiction, this paper carries out statistical analysis and proposes targeted measures for differential operation and maintenance management to ensure the safe and stable operation of the＂three-span＂transmission line.
