摘要： An object of the present invention is to provide an arcing horn system having a highly efficient dynamic current shutoff property including a dynamic current shutoff capability, for example, enough for the short circuit fault and other object thereof is to provide an arcing horn system capable of repeatedly maintaining the good dynamic current shutoff capability.
In an arcing horn system, an insulative tube 21 for surrounding a front end side of an arcing horn 11, 12 is provided and an air vent 21 a communicating from a front end portion of the arcing horn 11, 12 to a front end surface of the insulative tube 21 is formed on the insulative tube 21, so that the arc jet is blown off from the air vent 21 a upon the flashover in accordance with the thunder stroke. The insulative tube 21 is made of a polyamide resin. A cap 30 for covering the front end side of the insulative tube 21 is disposed so as to prevent the intrusion of the rain water into the air vent 21 a.
