PURPOSE:To make the whole of equipment more compact and easily handlable by constituting the equipment with a box body, a base frame, drum frame and roof body, providing a projected portion at the center of roof body, locating flat attaching surfaces at both sides of the projected portion, and providing suspending fittings on the attaching surfaces. CONSTITUTION:The box body comprises 3 elements of a base frame 1, a drum frame 2 of a cubical shape placed on this base frame 1, and a roof body installed on the drum frame 2. The roof body has a projected portion 4 swelled in a circular arc form upwardly at the center, has horizontal attaching surfaces 5, and suspending fittings 6 are placed on the attaching surfaces 5. A transformer 12 for circuit and a load switch 13 are housed inside the drum frame 2. The roof body forms a space 14 inside by the projected portion 14, thereby making the arrangement of built-in air ventilator and instrument transformer 15 effective and easier. Mounting position of suspension fittings 6 is lower than the projected portion 4 and thus does not project out from the outer shape of the whole of equipment so that does not disturb carrying or the like. By doing this, the whole of the cubicle high voltage equipment can be made smaller and handled more easily. |
