The new type device has no zinc oxide element, and it composes of an insulation tube and electrodes. The tube-arrester demonstrates the lightning protection performance and dynamic current interception performance by creeping discharge in the insulation tube when the lightning overvoltage is generated on a power distribution line. The aim of this study is to obtain data concering long-term reliability of the tube-arrester. In this paper, the tube-arrester was operated repetitively by large lightning impulse current, and the durabillty of the tube-arrester and the change in the electrical characteristics were examined. And also the electrical characteristics were examined when the rainwater was infiltrated in the insulation tube of the tube-arrester. When the rainwater was infiltrated in the tube, the discharge phenomenon was also observed with a high-speed camera. In addition, the operation characteristics of the 22kV distribution system tube-horn were examined.}, pages = {89--95}, title = {沿面放電型避雷装置の長期信頼性に関する研究}, volume = {34}, year = {2005}, yomi = {ヒダカ, シンスケ and オカムラ, タケル and オオツボ, マサヒサ and ホンダ, チカヒサ and ソイ, ヒロタカ and オカムラ, タケル} }
