数据采集是可靠的;在运行状态下

橡胶应力锥应力的变化和电压有关

电压越高应力锥应力变化越大。

Abstract

Investigating stress variation of prefabricated rubber stress cone is necessary for understanding interface pressure variation of high voltage cable terminal in operation.Therefore

a field measurement method is presented in this paper according to the structural features of the HV cable terminal in order to obtain the variation rule of cable terminal interface pressure.The initial strain is measured utilizing a static strain gauge to calculate the initial pressure on the stress cone.The strain variation is also measured adopting a dynamic strain gauge to calculate the stress variation rule in the rubber stress cone in operation for reflecting the interface pressure variation.The test results verify the feasibility and reliability of the measurement method

and indicate a positive voltage dependence of stress variation in the rubber stress cone of a high voltage cable terminal.
