基于热红外成像技术的绝缘子故障分类研究

针对停电测量绝缘电阻或带电测量分布电压等检零方式在实际操作中,都存在停电范围大、人员安全风险高、检测周期无法保证等问题,本文分析了盘形悬式瓷绝缘子红外精确测温的数据,并通过专家经验总结出利用红外热图的绝缘子故障分类研究。对绝缘子可能出现的故障类型通过绝缘电阻测试、绝缘子电压分布测试、泄漏电流测试、交流耐压测试等试验手段验证最终的热红外成像故障分析结果。

Insulator Fault Diagnosis based on Thermal Infrared Imaging System

Aim at power outage or charged insulation resistance measurement distribution voltage zero detection approach in practice, there are large range of power, personnel safety risk is high, there is no guarantee that the problem such as testing cycle, this paper analyzes the disc hanging porcelain insulator infrared temperature measurement data precision, and through the expert experience summed up the use of infrared heat insulator fault classification research. Possible fault types of insulator by voltage distribution test, insulation resistance testing, insulator leakage current test means such as test, ac withstand voltage test to verify the final failure analysis of thermal infrared imaging results.
