摘要：
A transformer enclosure has a hood and sill attached to a tank. The hood is retractable upon hinges connected to the top face of the tank. The sill is attached to the front face of the tank near the base and has a gate that drops down to an expanded position. When the enclosure is in a closed position, the hood and sill meet with the sill gate fully retracted along a tamperproof interface. A tamperproof interface is formed at the side of the enclosure by a flange on the side panels of the sill and a baffle on the bottom edges of the hood. A tamperproof interface is formed at the front of the enclosure by a bend and lip formed in the front panel of the hood in cooperation with a recessed portion formed in the gate.
