Claims

[Scope of utility model registration request]

- For the lead-out conductor of the bushing that protrudes from the case of the transformer, there is a connection between the lead-out conductor and the case between the screw fitting provided at the top that screws into the lead-out conductor and the discharge fitting fitted to the outer peripheral surface of the lower part. A grip for connecting wires made of an insulating member is screwed onto which a discharge gap is formed with a gap length set to cause discharge to occur in advance of the discharge starting voltage of A current limiter consisting of a current limiting element, an insulating material covering a part of both flat terminals and the outer peripheral surface of the current limiting element, a lead wire connected to the upper terminal, and a mounting bracket connected to the lower terminal. Connect the flow element unit to the suspension bracket of the case which is already grounded via the above mounting bracket, and connect the other end of the insulated lead wire, one end of which is connected to the above-mentioned upper terminal, to the discharge of the support body. A snow surge protection device for a pole-mounted transformer, characterized in that it is connected to a metal fitting.
