耐压击穿装置的容量指标

Capacity Performance Index of Voltage Resisting and Puncture Tester

根据影响介质击穿的主要因素,本文着重阐述了交流抗电击穿装置的容量指标问题。在确定耐压击穿装置的容量时,不仅要考虑到被试样件两极之间的等效电容值,同时还要估计到样件在击穿过程中可能产生的最大击穿电流值。对于某种绝缘材料或构件,合理选定耐压击穿装置的容量对正确进行试验是很重要的。

On the basis of primary influencing puncture of mediums, this paper emphatically points out the Capacity Performance Index of Voltage-resisting and Puncture tester. Before the capacity of tester is defined, the equivalent capacitance of test sample between electrodes, must be considered and the highest puncture current value of test sample producing in the puncturing course must be estimated first . It is very important to choose rationally the capacity of voltage-resetting and puncture test for some insulating material and components.
