At this time, the door 120 of the present invention is rotated by the sliding conveyance on the enclosure body (110). That is, unlike a sliding door that opens and closes only by rotation as in a general door, or a sliding door that opens and closes only by sliding, the door is opened and closed at the same time as the sliding operation and the rotation operation.

The enclosure main body 110 may be applied to any one of a main body of a high voltage switchgear, a low pressure switchgear, a distribution board, a junction box, a motor control panel, and an ESS according to a structure or a type of facilities mounted therein. For example, the main body of the enclosure 110 is a main body of a switchgear equipped with power equipment such as VCB, VCS, VC, ACB, MCCB, PCB and reactor, inverter, capacitor, measurement control module, SMPS, EMI filter and transformer. Can be applied as

The enclosure body 110 has a substantially rectangular parallelepiped shape, and has left and right side surfaces, a rear surface and an upper and lower surface formed therein, and an opening portion formed in the front surface thereof. Of course, the shape of the enclosure body 110 is not limited thereto, and may be formed in a polyhedron or sphere shape including a rectangular parallelepiped. And the front opening 111 of the enclosure body 110 is provided with a door 120 for selectively shielding the opened space. In addition, the bottom surface of the enclosure body 110 may be provided with a dustproof device (not shown) or a seismic isolator to cope with an external force such as an earthquake between the installation surface (for example, the ground).

The door 120 is described as an example that is provided in pairs to face each other so as to shield the front of the enclosure body 110 on both sides, it may be provided as a single door. In addition, the door lock 121 may be provided on the door 120, and a transparent confirmation window (not shown) may be provided to check the inside of the door 120 from the outside of the enclosure body 110.

Door 120 is rotated with the sliding movement through the guide unit 130 to be described later is made the opening and closing process. The door 120 is opened in a closed state and is inserted into some enclosure main body 110, and the other part protrudes out of the enclosure main body 110.

Door 120 is made to have a set thickness range, the inside is provided with a pad member 123 to provide a heat insulation or sound absorption function. For example, the thickness of the door 120 is about 100 mm, and the pad member 123 may be embedded therein. At this time, since the door 120 is made of an insulating material and requires a rigidity capable of covering the front surface of the enclosure body 110, the door 120 is preferably made of engineering plastic. Such engineering plastics can be applied to door materials of large enclosure bodies because of their excellent strength, elasticity, impact resistance, abrasion resistance, heat resistance, cold resistance, chemical resistance, and electrical insulation. In addition, fiber reinforced plastics (FRP), which is a composite material exhibiting more powerful properties by mixing engineering plastics with glass fiber or carbon fiber, may be formed of a door material. Of course, the door 120 may be basically implemented as a steel material of aluminum or stainless steel and steel sheet.

The door 120 has a curved surface 124 or an inclined surface that is bent backward from the front of the enclosure body 110. That is, even when a strong wind blows toward the door 120 by bending the front surface of the door 120 corresponding to the front surface of the enclosure main body 110 in a closed state in the state in which the door 120 is closed. Can be dispersed while supporting efficiently. In addition, since the front surface of the door 120 is made of the same curved surface or inclined surface in the vertical direction, and achieves the same curvature in the left and right directions of the door 120, the effect of increasing the rigidity in the vertical direction of the door 120 can also be expected. In addition, since the door 120 is made of an insulating material, a potential difference with the power equipment inside the enclosure main body 110 does not occur, thereby preventing a safety accident from occurring even when a user (eg, an operator) contacts the door 120 from the outside. can do. In addition, although not shown in the drawings, the curved curved surface 124 or the inclined surface of the door 120 may be formed of a convex curved surface or inclined surface protruding outward from the front of the enclosure body 110, the door 120 of the enclosure body 110 In the lower region or the upper region, a curved or inclined surface structure corresponding to the curved or inclined surface of the door 120 may be formed.

The upper and lower surfaces of the door 120 are provided with a pair of fixed hinges 125 and 126 having a limited conveyance range through the guide part 130. Of course, the fixing hinge may be provided only on one side of the upper or lower surface of the door 120 according to the size or weight of the door.

The fixed hinges 125 and 126 include a first fixed hinge 125 disposed adjacent to the outer edge of the door 120 and a second fixed hinge 126 disposed adjacent to the center of the door 120. . The first fixed hinge 125 and the second fixed hinge 126 may be provided with at least one or a plurality of bearings 127, the bearing 127 provides a function to reduce the friction force with the guide portion 130 do. In addition, the door 120 may maintain a fixed state on the enclosure body 110 and reduce frictional force in the sliding conveyance. Although not shown in the drawings, the door 120 is coupled to be slidably transported or rotated around at least the opening 111 of the enclosure body 110. The fixed hinges 125 and 126 may be made of a metal material separate from the door 120 and may be made of the same material as the door for insulation. In addition, the door lock 121 provided on the front of the door 120 may also be made of the same material or at least an insulating material for the door 120 for insulation.

And on one door 120, the distance between the first fixed hinge 125 and the second fixed hinge 126 is in the range of 20 to 50% with respect to the width of the door 120 (proportion 1: 2 to 1: 5). It can be made of). More preferably, the entire width of the door 120 (including the distance between the fixed hinges) and the distance between the pair of the fixed hinges 125 and 126 may be 1: 3. The ratio of 1: 3 can withstand the wind pressure applied in front of the door 120 and at the same time can effectively reduce the dead space generated inside the enclosure body 110. Herein, the ratio of the width of the door 120 to the distance between the pair of fixed hinges 125 and 126 may be changed in consideration of characteristics according to regions or installation positions. Thus, the door 120 using a pair of fixed hinges (125, 126) can safely withstand the wind pressure from the front, it can prevent the sudden opening and closing of the door has the effect of preventing a safety accident.

The door 120 is opened and closed by the guide part 130 on the enclosure main body 110.

Guide portion 130 is provided on the upper portion of the corner portion adjacent the front and side of the enclosure body (110). Of course, in the structure in which the door 120 is fixed at both the upper and lower portions, another guide portion may be separately disposed at the lower portion of the enclosure body 110.

Guide portion 130 is bent in a substantially "L" shape, the first guide member 131 adjacent to the front surface of the enclosure body 110, and the second guide member 132 adjacent to the side of the enclosure body 110 The shape of the guide part 130 is preferably that the first guide member 131 and the second guide member 132 are formed at an angle of at least 90 degrees or more.

The first guide member 131 and the second guide member 132 have a transport space 133 is formed so that the fixed hinges (125, 126) are accommodated therein. At this time, the transport space 133 inside the first guide member 131 and the second guide member 132 is formed to communicate with each other.

The connecting portion between the first guide member 131 and the second guide member 132 is provided with an inclined plate 134 in contact with the fixed hinge. The inclined plate 134 interferes with the first fixing hinge 125 facing the second guide member 132 in the process of opening the door 120, and the second fixing hinge 126 in the process of closing the door 120. ) Are interfered to face the first guide member 131. That is, the inclined plate 134 is in contact with the fixed hinges (125, 126) so that the door 120 is opened and closed smoothly on the guide portion 130. The inclined plate 134 may be positioned on the transfer space 133 of the guide unit 130 or may be disposed outside the transfer space 133.

The guide part 130 includes one or a plurality of stoppers 135 that interfere with the first fixed hinge 125 or the second fixed hinge 126 in the transport space 133. The first stopper 135a interferes in the direction in which the door 120 is closed to maintain the set opening range (eg, about 1/3 or 2/3 opening point) in the process of opening the door 120. For example, when the user opens the door about 2/3 and the door 120 passes the first stopper 135a (when the fixed hinge passes after contacting the stopper), the door 120 is closed in the direction of closing. Since it interferes with one stopper 135a, it can be kept about 2/3 open.

In addition, the second stopper 135b may be further provided on the guide part 130 to keep the door 120 fully open. For example, when the door 120 is fully opened, the first fixing hinge 125 is disposed to be adjacent to the end of the second guide member 132, and the second stopper 135b is positioned at this position on the guide 130. If provided, it is possible to maintain the fully open state of the door 120.

The stopper 135 has a structure that protrudes into the transport space 133 on the guide part 130 and protrudes into the transport space 133 or is in contact with the fixed hinges 125 and 126. 133) It is preferable to have a structure that is pushed outward. In addition, the position of the stopper 135 may be changed according to a range in which the door 120 is mainly opened, and a larger number of stoppers may be provided according to the opening degree of the door 120.

The door 120 may be provided with a door closer (not shown) that exerts a force in the closing direction. Then, the door 120 may be disposed so that the stopper 135 interferes only in the closing direction of the door 120 because a constant force is always applied in the closing direction. Although not shown in the drawings, the door closer may be provided to press a part of the door 120 (side or corner area), or may be provided to press any one of the pair of fixed hinges 125 and 126. .

Looking at the process of opening and closing the door 120 on the guide portion 130 as follows.

First, when the user grips the door 120 handle (not shown) or the door lock 121 and pushes the door 120 in the opening direction, the sliding movement of the door 120 is performed first. At this time, the first fixing hinge 125 is switched in the direction from the first guide member 131 to the second guide member 132 while contacting the inclined plate 134.

As the first fixed hinge 125 enters the transfer space 133 of the second guide member 132, the door 120 rotates simultaneously with the sliding transfer. At this time, the dead space (112) is generated while the door 120 slides and moves and rotates inside the enclosure main body 110, which is negligible compared with the total volume inside the enclosure main body 110. In addition, it is possible to adjust the power equipment arrangement inside the enclosure body 110 so as not to interfere on the dead space (112).

When the door 120 is opened and the second fixing hinge 126 passes through the first stopper 135a, the door 120 is kept open while maintaining the set opening range.

When the door 120 is pushed further and fully opened, the door 120 may be fully opened because the first fixing hinge 125 interferes with the second stopper 135b.

When the door 120 is closed again, the second fixing hinge 126 is in contact with the inclined plate 134 and the transport space 133 of the first guide member 131 from the transport space 133 of the second guide member 132. Direction is switched to. After that, the process of closing the door 120 is performed in the reverse of the door opening process.
