Further, the two right-angle folded sections of the first folded plate are provided with module holes, and the module holes comprise square holes and/or round holes which are arranged at intervals.
The utility model provides a three switch board cabinet bodies that open door, includes the frame, the frame include four vertical stands, be fixed with the back timber between the adjacent stand, the cabinet door is installed to three side among them of the cabinet body, the cabinet door is articulated with the stand of corresponding position, the backplate is installed to another side on the cabinet body, stand and/or back timber adopt the section bar as above.
Further, the cabinet door is connected with the upright post through a hinge, one end of the hinge is fixed on a certain folded section in the middle of the W-shaped folded plate, and the other end of the hinge is fixed with the cabinet door.
Further, the cabinet door on be fixed with polyurethane rubber coating foaming sealing strip, when the cabinet door is in the state of closing the door, polyurethane rubber coating foaming sealing strip compress tightly with the edge of the first folded plate of corresponding position.
Further, a side cross beam is fixed between the adjacent upright posts, and the end part of the side cross beam is matched with the modulus hole of the second folding plate.
Furthermore, the side cross beams, the top beams and the stand columns are all made of the sectional materials.
Further, the upright posts are connected with the top beams at the two sides through tee joints.
The beneficial effects are that:
(1) The sectional material structure can realize the installation of the three-door;
(2) The edge of the wrapping edge of the right-angle folded plate of the profile is square-tooth-shaped or zigzag, so that when a certain position of the wrapping edge of the right-angle folded plate is subjected to external force, the wrapping edge is only partially lifted at the stressed position, and is lifted to the root of the tooth shape at most, and the wrapping edge cannot be lifted integrally, thereby improving the structural stability of the upright post or the top beam;
(3) The two right-angle folded sections of the second folded plate are provided with modulus holes, so that the second folded plate is convenient to be connected with other sectional materials.
(4) The protection grade of IP55 can be achieved by the existing power distribution cabinet, but due to the structural problem of the section bar, the single door opening design can be only achieved. The invention can realize three doors on the premise of ensuring the protection level IP55, the design of the three doors greatly improves the maintenance efficiency of the power distribution cabinet, and the specific mode of the protection level IP55 is realized: when the door is closed, the edge of the section bar can be pressed to the polyurethane glue-coated foaming sealing strip on the door plate to form a seal.
