초록

Electrostatic eliminators are essential in various areas of manufacturing industries to protect electrostatic hazards and to reduce inferior products. For ion sources used in the charge neutralizers, there are corona discharge, soft X-ray, and ultraviolet and glow discharge. Among them, corona discharge is generally used, because the corona discharge can easily and economically produce positive and negative ions including electrons in air at atmospheric pressure. But it is necessary to equip explosion-protection electrostatic eliminators wherever hazardous atmosphere. The electrostatic eliminators and their testing method of explosion-protection type have been developed in this research. The contents and scope of the research as follows; developing the type 'Ex s IIB T4' electrostatic eliminator of explosion-protection; developing the type 'Ex s d IIB T4' electrostatic eliminator of explosion-protection; developing the explosion-protection performance testing method of electrostatic eliminator for using AC power source.
