空气绝缘恢复特性的分析方法、装置、设备及介质
摘要：
本发明公开了一种空气绝缘恢复特性的分析方法，包括：获取空气间隙放电通道绝缘恢复过程中的两张纹影图像；其中，两张所述纹影图像的拍摄间隔时间不超过预设的拍摄间隔时间；根据预设的光流法对所述纹影图像进行计算，得到所述空气间隙放电通道的加热气体速度分布场；根据所述空气间隙放电通道的加热气体速度分布场确定所述空气间隙放电通道的绝缘恢复时间。本发明实施例还提供了空气绝缘恢复特性的分析装置、设备及介质，采用多个实施例解决了现有技术电力系统不能准确选取重合闸的时间的问题。
摘要（英）：

The invention discloses an air insulation recovery characteristics analysis method, comprising the following steps: acquiring two schlieren images in the insulation recovery process of an air gap discharge channel, wherein the shooting interval time of the two schlieren images does not exceed the preset shooting interval time; calculating the schlieren image according to a preset optical flow method to obtain a heating gas speed distribution field of the air gap discharge channel; and determining the insulation recovery time of the air gap discharge channel according to the heating gas speed distribution field of the air gap discharge channel. The embodiment of the invention further provides an air insulation recovery characteristics analysis apparatus and device and a medium. By adoptingthe multiple embodiments, the problem that the reclosing time cannot be accurately selected by a power system in the prior art is solved.
