PURPOSE:To prevent the deformation of a shutter by providing a plate-shaped shutter, which screens the charge part on the fixation side inside a panel when a truck-type equipment is pulled out of the enclosed switchboard, with a longitudinal bent and a projection and reinforcing material. CONSTITUTION:Shutters 3B and 3C for screening the charge parts 4 and 4 on fixation side inside an enclosed switchboard, which are exposed when pullout equipment, for example, a breaker is pulled out of the frame 5 of the board, are slid from above and below to prevent danger. A bend 6 is formed in the longitudinal direction of the plate which forms the shutter 3B or 3C, and a projection for operation is provided on the opposite of a charge part, or several pieces of reinforcing materials 9 are formed in longitudinal direction of the same side as the charge part and on the opposite side to it. Hereby, the flexure of the shutter is prevented, and the dimensions of the intervals between the shutter and the charge part on fixation side and the truck-type equipment are reduced, and the opening and closing of the shutter can be performed without hindrance. |
