摘要
特高压变电站工程建设中,弧垂检查是软母线施工的关键环节,重点在于保证弧垂观测的准确度和可操作性。提出直接测量法、中间点法、等长观测法、异长法、角度法5种特高压变电站软母线安装完成后弧垂的测量方法,并进行分析比较,可用于指导弧垂复测。
In the construction of UHV substation,sag inspection is a crucial step of the soft bus construction. The key point is to ensure the accuracy and operability of sag observation. Five measuring methods of sag after installation of soft busbar in UHV substation are proposed including direct measuring method,midpoint method,equal length observation method,different length method and angle method. These methods are analyzed and compared,which can be used to guide sag re-measurement.
