Claims

[Scope of utility model registration request]

For one pair (two) of lid fastening metal fittings facing each other among at least four or more lid fastening metal fittings provided around the upper part of the case for removably fastening the case lid to the case body. , insert a plate-shaped support fitting with mounting holes for tightening at both ends so that it is parallel to the top surface of the case lid, and connect the mounting holes at both ends of the support fitting to the tightening bolts of the lid tightening fitting. In addition to being tightened at the same time as the insertion case lid, the support fitting also includes an insulated container with a built-in non-current current limiting element, an upper lead wire provided at the top of the container that connects to the current limiting element, and a current limiting element. Connect the current-limiting element unit to the bolt-shaped lower terminal provided at the bottom of the container that is connected to the unit by inserting the lower terminal of the unit into the unit mounting hole formed in the support fitting and attaching it with a nut. A mounting structure for a current-limiting element unit in a pole-mounted transformer, characterized in that the above-mentioned upper lead wire is connected to an outlet wire of the transformer or a high-voltage underline wire connected to the outlet wire.
