Abstract: 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.

Abstract: Una caja para transformador tiene una cubierta y umbral unidos a un tanque. La cubierta es retráctil sobre bisagras conectadas a la cara superior del tanque. El umbral se fija a la cara frontal del tanque cerca de la base y tiene una puerta que desciende a una posición expandida. Cuando la caja está en una posición cerrada, la cubierta y el umbral se encuentran con la puerta con umbral completamente retraída a lo largo de una superficie de contacto a prueba de manipulación. Una superficie de contacto a prueba de manipulación se forma en el lado de la caja por una saliente en los paneles laterales del umbral y un deflector en los bordes inferiores de la cubierta. Una superficie de contacto a prueba de manipulación se forma en la parte frontal de la caja por una curvatura y el borde formado en el panel frontal de la cubierta, en cooperación con una porción con huecos formada en la puerta.
