摘要

带有弹簧压力系统的电缆附件

如果界面接触应力不足

则易出现放电现象;如果界面接触应力太大则可能导致电缆绝缘缩径。笔者通过电气性能试验确定了220 kV交联电缆干式GIS终端应用硅橡胶应力锥时所需的弹簧压力。通过冷态、热态试验验证了所设计弹簧系统的可靠性。最后应用ANSYS软件计算了在弹簧压力和过盈装配共同作用下的GIS终端界面接触应力。

Abstract

For the cable accessories with spring pressure system

discharge is easy to happen if the interface contact stress is insufficient

and the cable insulation necking is able to appear if the interface contact stress is too large.This paper has confirmed the spring pressure required by the interface when dry type GIS terminations use silicone stress cone for 220 kV XLPE cable through electrical performance test.Reliability of the spring system designed has been verificated by cold and hot test.At last

under the combined action of spring pressure and interference fitting

the interface contact stress is calculated by ANSYS.
