摘要
由于敞开式隔离开关恶劣的运行环境,在长期运行后往往出现分合不到位等问题,为解决隔离开关开合状态识别问题,本文提出了一种基于中线模型的对开式隔离开关开合状态自动检测的方法。通过建立对开式隔离开关的中线模型,识别并绘制刀闸臂边缘线,根据边缘线角度计算分析刀闸状态,通过分析结果及时进行预警。根据该方法进行隔离开关实验验证,结果表明本方法可以准确分析隔离开关分合状态,极大地提高了隔离开关状态识别准确性及及时性,具有重要的实际应用价值。
Due to the harsh operating environment of the open-type isolating switch,there are often problems such as insufficient opening and closing after long-term operation.In order to identify the switching state of disconnecting switches,this paper proposes an automatic switching state detection method for disconnecting switches based on midline model.Through building the midline model,the edge lines of the breaker arms can be distinguished and drawed.According to the angle of the edge lines,the breaker status can be analyzed,and the result can alarm in advance.The method is verified by the isolating switch experiment.Experiment results show that the proposed method can help precisely determine the edge lines of breaker arms,implement disconnecting switch status recognition accurately,and is of significant value to application.
