<p>PURPOSE:To reduce an area of installing a substation and to delete a construction cost of a trestle foundation. CONSTITUTION:A box 8 containing an auxiliary transformer 10, etc., to be used for a transformer for a capacitor type instrument therein is provided, and a wall tube insulator 1 is implanted on an upper part of the box 8. A voltage dividing capacitor 2 formed in a hollow cylindrical shape is contained in the insulator 1, and an arrester 3 is further contained inside the capacitor 2. A capacitor element 21 of the capacitor 2 is connected in parallel with a zinc oxide element 31 of the arrester 3 via a connecting conductor 4.</p> |
