<p><P>PROBLEM TO BE SOLVED: To provide a device for issuing an alarm when power supply stops during indirect hot line work. <P>SOLUTION: A non-charged alarm for high voltage indirect hot line includes a body 1 having an arc-like arm 6 storing a control circuit 5 inside, a wire receptacle 2 arranged at a tip face of the arc-like arm, a weight 3 pivoted to a base end of the arc-like arm so that it freely rocks, and an operation piece 4 supporting an intermediate part in a part close to the tip of the body so that it freely rocks. A space between facing surfaces of the wire receptacle and the arc-like arm is formed in a wire storage space 8. A control circuit is stored inside the body corresponding to the wire storage space. A side positioned in one rocking fulcrum in the operation piece is formed in an arc-like receptacle part 9 coming into/out from the wire storage space, and a side positioned in the other rocking fulcrum at the operation piece is formed in a ring-like fitting part 12 held by an insulated operation tool. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
