全景热成像感知系统在输变电设备巡检检测中的应用
【目的】旨在探讨全景热成像感知系统在输变电设备温度状态监测中的应用及其技术优化,以解决传统人工巡检和接触式测温方法效率低、安全性不足等问题,提升电力系统的安全性和智能化水平。【方法】通过结合非接触式红外测温、双光融合(热成像与可见光融合)、多传感器集成(如局放传感器)等技术,系统采用热成像传感器实时采集电力设备温度数据,并基于可视化图像分析、阈值报警及全天候监测功能,实现对设备异常发热的智能化识别与预警。设计了3 种高低压系统方案(如热成像传感器与数据平台的有线/ 无线传输架构),验证其适用性。【结果】实际应用表明,该系统在可对重点设备部件进行热成像监控,东北某企业10 kV 开关站中成功检测到刀闸温度异常(177.5℃),避免了潜在设备故障;其非接触式测温模式避免了金属脱落风险,单台设备可覆盖多目标监测,减少人工巡检工作量。系统支持超温预警(±0.5℃精度)、历史数据追溯及多种报警机制(如温度突变预警),综合降低企业经济损失达百万元以上。【结论】全景热成像感知系统可优化电力设备运检流程,提升供电可靠性和安全性,为智能电网建设提供重要技术支撑。
