ZnO压敏陶瓷材料导纳谱的自动测试

Automatic Measurement of Admittance Spectroscopy for ZnO Varistors

阐述了ＺｎＯ压敏陶瓷材料导纳谱测试的原理和方法，重点介绍了作者组建的自动测试系统以及由该系统测得的某些ＺｎＯ压敏陶瓷试样的Ｄ～ｆ、Ｇ～Ｔ和Ｃ’～Ｃ”曲线。

The auto measurement of admittance spectroscopy for ZnO varistors is introduced in this paper. An auto measuring system built by the authors is described, some D-f, G-T and C'-C' curves measured by the system are givenand discussed.
