る柱上変圧器の耐雷装置。[Claims for Utility Model Registration] 1. A current-limiting element 1c with non-linear voltage-current characteristics is interposed between the discharge electrode 1a and the ground electrode 1b, and the current-limiting element 1c with non-linear voltage-current characteristics is integrally covered with a jacket 1d made of an elastic insulating material. The current limiting element unit 1 is attached with the ground electrode 1b to the metal protector 4 of the partial bushing 3 attached to the ground case 2, and the discharge electrode 1a is partially opposed to the bushing terminal portion 3a of the bushing 3. A lightning protection device for a pole-mounted transformer, characterized in that an air gap is formed between them. 2 The metal protector 4 includes a frame-shaped main body 4a whose base is attached to the grounding case 2, and a current-limiting element unit support part 5 which is removably connected to the frame-shaped main body 4a with a support leg 5a formed by bending at the base part of the frame-shaped main body 4a. Therefore, the current-limiting element unit 1 is connected to the current-limiting element unit supporting part 5 with its ground electrode 1b and is attached to the metal protector 4. Lightning protection device for transformers. 3. The current limiting element unit 1 is equipped with an inverted cap 15 around the discharge electrode 1a to prevent bridging during water injection. Lightning protection device for transformers.
