Suspension curve equation of jumper wire in substations
摘要
Abstract
Jumper wire consists of strain clamp and flexible wire in substations.In the respective coordinates,the force models of strain clamp and flexible wire are analyzed to set up each suspension curve equations.The suspension curve equation of jumper wire is unified by the coordinate transformation for flexible wire.Then the length and the sag of the suspension curve equations for jumper wire is calculated in Matlab code.Finally,the suspension curve equations are verified by using the practical parameters in 1 000 kV substations to meet the engineering demand completely,since the error between the practical sag and the design sag is less than 0.5％,less than 2％～-2.5％ in practical engineering.关键词
