Claims

[Scope of utility model registration request]

The area between the live part and the case of the primary bushing of a pole-mounted transformer is the weakest point in terms of insulation level, and a flash fault is caused at that point in advance so that the follow-on current generated during the flash fault is transferred to the primary bushing. In the case where the fuse is installed in the fuse tube of the high-voltage cutout to be connected, the fuse tube used for the high-voltage cutout is loaded into the insulating tube and the ends are connected to the top and bottom of the outer peripheral surface of the insulating tube. In addition to the fuses for cutting off the following flow, which are connected to the upper and lower electrodes fixed to the upper and lower electrodes, the outer circumferential surface of the insulating tube is interposed between the upper and lower vehicle poles, and the electrode at one end is connected to the upper electrode at the other end. 1. A high-voltage cutout fuse tube, characterized in that a voltage nonlinear resistance element made of a sintered body mainly composed of zinc oxide is provided, each of which has an electrode connected to a lower electrode.
