Gaoya dianqi局部放电检测技术是开关柜绝缘检测的有效手段之一。文中采用暂态地电压法、空气式超声波法、特高频法和红外热成像检测法对一起35 kV开关柜的绝缘缺陷进行检测，结合其放电图谱及特性判定开关柜母线室内发生多处沿面放电。通过开关柜停电解体检查发现，柜顶的散热铁丝网因盐雾腐蚀锈蚀严重，母线室内绝缘件表面附着的铁锈和盐分致使母线绝缘水平严重降低。为防止类似缺陷的发生，建议沿海地区的变电站应严控高压室室内环境，并常态化开展局部放电检测；在开关柜设计阶段，应增强柜体防盐雾腐蚀性能，且柜顶严禁设置直通式风道。

Dianci bileiqi提出了一种基于红外热成像（IRT）图片的非接触式瓷绝缘子故障诊断方法，用于对架空电力绝缘子进行自动监测和视觉检查。首先采用最优阈值法对IRT图像中的重点区域进行分割。随后，从分割的重点区域中计算出各种几何、形态、强度和统计特征，作为XGBoost分类器的输入，最终利用图像处理技术和基于XGBoost的分类器模型开发出零值和低值绝缘子状态分类方法。研究表明，XGBoost分类器各项指标均为最优，精度（ACC）可达98.00%，真阳性率（TPR）为93.55%，而假阳性率（FPR）仅为1.49 ...
