典型植被颗粒对导线-板间隙放电特性的影响研究

In order to analyze the influence of the typical vegetation particles on the discharge characteristics of conductor-plane air gap, in this paper experimental studies are conducted on the AC breakdown characteristics of gap under typical vegetation particles condition by using simulation test platform. In order to analyze the influence mechanism of multiple particles on the breakdown characteristics, the simulation model has been built. The results show that the effect of the ashes and particles lead to a great decline of the dielectric strength of the air gap under AC voltage, which is reduced to about 60% of that air gap under standard atmosphere .
