摘要

针对高压隔离开关安装过程中触指压力的检测需求

提出了一种可在分合闸过程中实时连续测力的新型触头。采用机械原理

推导了触头受力和触指变形之间的关系。在考虑实际工况的前提下

给出了测力触头的结构设计。最后在所建的高压隔离开关试验平台上对隔离开关分合闸运动过程中的触头压力进行了测试。试验结果表明:设计的测力触头可以对触指压力进行实时连续检测

连杆长度的变化会使触头触指啮合位置不正

触指单边压力增大;根据触指压力变化曲线可以判断单相导电臂分合闸同步性和三相同期性检测。因此

该新型测力触头可对高压隔离开关的安装提供帮助指导。

Abstract

In order to meet the testing requirements of contact-finger-pressure in the installation process of high voltage disconnector

a new type of contact with real-time continuous force measurement in the open and close process is proposed.Based on mechanical principles

the relation between the contact pressure and the contact deformation is derived.After that

the structural design of the contact is given in consideration of its actual working conditions.Finally

a high voltage disconnector test platform is adopted to test the contact pressure during the open and close processes of the disconnector.Experimental results indicate that the designed contact head can continuously measure the contact pressure in real time.Moreover

changes of the link length lead to the malposition between the contact and the contact finger

and the unilateral pressure of the contact finger increases.Based on pressure curves of the contact finger

the open and close synchronization of single-phase conductive arm can be obtained

and the threephase-periodicity detection method of the disconnector is also acquired.Accordingly

the new contact for force detection can help and guide the installation of the high voltage disconnector.
