Abstract

Pollution flashover accident seriously threatens the security and stability of power grid. It is very important to clean the contaminated insulator to avoid pollution flashover accident. In view of the shortcomings of the traditional cleaning methods, a novel method of 1064 nm pulse laser cleaning insulator contamination is proposed in this paper. The finite element simulation model of laser cleaning insulator contamination is established and the numerical simulation calculation is carried out. The distribution characteristics of temperature field in the process of laser cleaning are obtained by simulation. The results show that the temperature in the center of the laser spot is the highest. When the laser power is 50 W, the maximum temperature of the contamination layer reaches to 411 K. The temperature gradually decreases along the radial direction, and decreases to 312 K at the edge of the spot. The temperature decreases rapidly in the depth direction. The influence of laser power on the distribution of temperature field is analyzed and the maximum temperature of the contamination layer is linearly related to the laser power.

陶瓷绝缘子激光清洗过程中的温度场分布特性

污染闪络事故严重威胁着电网的安全稳定。对受污绝缘子进行清洗是避免污闪事故的重要措施。针对传统清洗方法的不足，提出了一种1064 nm脉冲激光清洗绝缘子污物的新方法。建立了激光清洗绝缘子污染的有限元仿真模型，并进行了数值模拟计算。通过仿真得到了激光清洗过程中温度场的分布特征。结果表明，激光光斑中心的温度最高。当激光功率为50 W时，污染层最高温度可达411 K。温度沿径向逐渐降低，在光斑边缘降至312 K。温度在深度方向上迅速下降。分析了激光功率对污染层温度场分布的影响，发现污染层的最高温度与激光功率呈线性关系。
