摘要
零值绝缘子威胁输电线路安全稳定运行。通过光纤电场检测方式可以获得绝缘子串局部电场分布,从而识别零值片。设计了一款光纤电场检测履带机器人,并为分析其在检测过程中可能产生的误差和影响,提出识别判据,建立了220 k V绝缘子串真型模型以及检测机器人等效模型,仿真分析了机器人构架在绝缘子串不同位置时的电场分布特性,并且研究了机器人材质、位置、尺寸等因素对局部电场畸变特征的影响,尤其是零值和非零值情况下的局部电场变化规律。研究结果揭示了光纤电场检测机器人对零值绝缘子局部电场畸变的影响,可为输配电外绝缘智慧运维提供技术支撑。
Zero value insulators threaten the safe and stable operation of transmission lines.Using the fiber optic electric field detection method,the local electric field distribution of insulator strings can be quickly detected,thereby identifying zero value insulator piece.A fiber optic electric field detection tracked robot is designed.To analyze the possible errors and impacts of fiber optic electric field detection robots during the detection process,an identification criteria is proposed.A true model of 220 kV insulator string and an equivalent model of fiber optic electric field detection robot are established.The electric field distribution characteristics of the robot architecture at different positions of the insulator string are simulated and analyzed.The influence of factors such as robot material,position,and size on the characteristics of local electric field distortion has been studied,especially the changes in local electric field under zero and non zero values.The research results reveal the influence of the fiber optic electric field detection robot on the local electric field distortion of zero value insulator,and thus provides technical support for the intelligent operation and maintenance of external insulation in power transmission and distribution.
