摘要

在夹在针状电极和平面电极之间的低密度聚乙烯(LDPE)薄膜上测量了热激电流(TSC)和热激表面电位(TSSP)，并对空间电荷进行了评价。为了证实注射是从针电极发生的，注射空间电荷被困在针尖周围，实验采用了不同数量的针电极，例如20个。最后，通过测量LDPE薄膜中的起始电压，探讨了空间电荷对LDPE薄膜中树形形成机制的影响

Thermally stimulated electrical measurement of an LDPE film stressed under a nonuniform electric field: influence of the space charge on treeing

The authors measured the TSC (thermally stimulated current) and TSSP (thermally stimulated surface potential) on low-density polyethylene (LDPE) films sandwiched between needle electrodes and plane electrodes, and then evaluated the space charges. To confirm that injection occurs from needle electrodes and that injection space charges are trapped around the needle tips, the experiments were carried out with different numbers of needle electrodes, e.g. 20. Finally, the authors examined the influence of the space charges on the mechanisms of treeing in an LDPE film by measuring the inception voltage of treeing in the film.<>
