As a new method to protect the spark gap from metal particle contamination,theeffect of the metal inserted insula.tor on the controlling behavior of metal particles was investigatedin a quasi-uniform electric field.Considering that the inserted metal electrodes can decrease theelectric field around the insulator and divert the electrostatic force away from the insulator,themethod can be used to prevent the particles from moving toward the insulator so as to reducethe possibility of a breakdown.The inserted metal electrodes can reverse the direction of theparticles' horizontal motion.A study on the insulator shape indicates that the inserted metalelectrodes can repulse the particle and improve the particle lifting voltage significantly near thevertical surface of the insulator or ribbed insulator.For the insulator with a tilting surface theinserted metal electrodes have little influence on the particle motion.In addition,the size of theinserted electrodes shows a significant,effect on the control of particle motion.

Canonsidering that the inserted metal electrodes can decrease the electric field around the insulator and divert the electrostatic force away from the insulator, themethod can be used to prevent the particles from moving toward the insulator so as to reduce the possibility of a breakdown. inserted by metal electrodes can reverse the direction of the particles' horizontal motion. A study on the insulator shape indicates that the inserted metalelectrodes can repulse the particle and improve the particle lifting voltage significantly near the vertical surface of the insulator or ribbed insulator. For the insulator with a tilting surface theinserted metal electrodes have little influence on the particle motion.In addition, the size of the unsserted electrodes shows a significant, effect on t he control of particle motion.
