Description

{Door distributing board}

The present invention relates to a switchgear for supplying power to a customer's side of a factory or building unit by converting a special high voltage of thousands to tens of thousands of V into a commercial low voltage of hundreds of V units, in particular, a low voltage section and a high voltage including a measurement control panel and the like. By providing a door that opens and closes in a rotational and sliding manner on one side of the switchgear provided with a high-pressure unit integrally including a transformer and a high-pressure fuse, thereby facilitating internal inspection of the switchgear and minimizing and installing the required area of the switchgear And it relates to a switchgear that can maximize the space utilization rate at the time of maintenance.

The switchgear is a facility that converts the special high voltage from 6,600V to 22,900V into a low voltage such as 380V, 220V, etc., and supplies it to the collective power demands, such as schools, buildings, apartment complexes, factories, etc., with the necessary power.

These switchgears (see Patent No. 300139) divide the high and low pressure sections in front and rear in one enclosure to minimize the installation area and to improve the efficiency of installation and operation management. Also, the high and low pressure sections are divided into upper and lower sections. It has a multi-layered structure of divided front and rear separation. Also, on his side, a viewing window for internal viewing and an inspection door for internal inspection are provided.

It has the advantage of facilitating ventilation.

As described above, in the conventional switchgear in which the high and low pressure sections are divided into front and rear sections, consideration is given to the open space of the observation space and the side inspection door through the side viewing window when installing on the site, and the door of the high pressure section and low pressure section can be sufficiently opened. In order to make it possible, the door opening spaces on the front and rear sides must be secured. Securing the door opening space of the high and low pressure parts is essential for maintenance and management of the switchgear.

However, the place where most switchboards are installed is installed in a closed and narrow space, such as a basement inside the building, especially in a space where three sides are surrounded by walls and the other one is open, in which case the switchboard is located inside the switchgear installation space. Since the door opening space of the door must be secured, the space for installation of the water switchboard needs to be significantly wider than the size of the switchboard.

In addition, when the switchgear is installed outside the building of the power recipient, a safety fence must be installed along the perimeter of the switchboard. At this time, as in the installation in the building, inevitably, to secure the door opening space of the low and high pressure parts, it is inevitable that This results in the installation area being significantly extended over the area of the main body of the switchgear.

Moreover, when installing the switchboard in a space where three sides of the building are closed, the work space for maintenance and inspection even if it is installed at a certain distance from the wall of the installation space in consideration of the opening angle of the high-pressure door or low-pressure door The lack of workability or the problem of expanding the installation space has been pointed out.

The present invention is to solve this problem, and more specifically, the door provided in the front of the switchgear can be opened and closed while rotating and simultaneously sliding to reduce the open area of the door, and also secure another working space. The purpose is to provide a switchgear that can be used.

1 to 5, the switchgear 100 according to an embodiment of the present invention includes an enclosure body 110, a door 120, a rotating part 130, and a first guide part 140.

First, the enclosure body 110 is provided with a power receiving facility and a distribution facility therein to provide a function for protecting a facility that converts high-voltage power to low-voltage. In general, it has a box-shaped shape, and may have exhaust means (not shown) for discharging internal air to the outside.

The enclosure body 110 is provided with a door 120 that can be opened and closed in the front to maintain the internal facilities. The door 120 may be provided by a casement method, a sliding method, or a sliding method, and additionally, logic may be applied to cut off the internal power while the door is opened. The enclosure body 110 is provided with a pair of support frames 114 supporting the upper frame 112, the lower frame 113, and side surfaces around the doorway 111 in which the door 120 is provided.

The rotation unit 130 is provided at the upper and lower portions of the door 120 to rotate the door 120. Of course, the rotating part 130 may be provided on only one of the upper and lower parts of the door 120. One end of the rotating portion 130 is coupled to the support frame 114, the other end is coupled to the corner portion of the door 120. At this time, the opening range of the door 120 may be changed according to a position where the rotating part 130 and the door 120 are coupled.

One end of the rotating part 130 is coupled to the support frame 114 and the first hinge 115, and the other end is coupled to the door 120 and the second hinge 121, and the first hinge 115 and the first 2 The relative rotation of the hinge 121 is made. In addition, the door 120 is disposed to protrude at least partially on the upper or lower edge of the door 120 in the fully open state or in the fully closed state. Of course, the rotating part 130 may be arranged to be hidden inside the door 120 at the top or bottom of the door 120 in the state where the door 120 is fully opened or completely closed.

At this time, the first hinge 115 and the second hinge 121 have the same rotational speed, so that the rotating part 130 is completely opened and closed by the rotation in the opening direction of the door 120 or rotation in the closing direction. There is no interference in operation. The rotating part 130 is preferably made of about 20 to 45% of the horizontal length of the door 120.

At this time, the first hinge 115 and the second hinge 121 may be connected to interlock inside the rotating unit 130.

In addition, at least one of the first hinge 115 and the second hinge 121 may be provided with a first speed reducer (not shown) for adjusting the speed in the process of closing the door 120. The first speed reducer may reduce the rotational speed of the rotating unit 130 to prevent the door 120 from suddenly closing.

In addition, since the rotating part 130 rotates at both ends to rotate the door 120 inward by the length of the rotating part 130, the radius at which the door 120 rotates outward can be reduced, so that the door 120 opening and closing space is reduced. do. Therefore, even if a switchgear of the same capacity is installed, since the door can be opened and closed in a smaller space, space efficiency is increased.

FIG. 6 is a perspective view showing a first guide portion provided on an upper part of the door of the switchgear shown in FIG. 1, and FIG. 7 is a reference diagram showing a state in which the door is fixed and returned to its original position in the first guide portion shown in FIG. 6 to be.

6 and 7, the first guide part 140 is disposed on the door 120 closed on the doorway 111 of the enclosure body 110, and the door 120 through the rotating part 130 It provides the function of sliding in the horizontal direction while rotating.

The first guide part 140 moves on the guide rail 141 and the guide rail 141 provided therein along the guide groove 116 formed long in the direction of the support frame 114 from the bottom surface of the upper frame 112 It includes a roller unit 142. Of course, although not shown in the drawing, it may be provided on the doorway 111, the second guide portion (not shown) is provided to correspond to the first guide portion 140 is disposed under the door 120.

The guide rail 141 has an approximately'c'-shaped cross section, and is formed to be long in a straight line.

The roller unit 142 includes a housing 143 and a plurality of rollers 144. The housing 143 is rotatably coupled to the protruding piece 122 protruding from the upper portion of the door 120. The housing 143 also has an approximately'U'-shaped cross section, and is arranged to surround the guide rail 141. A plurality of rolling rollers 144 are provided inside the housing 143, and the rollers 144 slide on the guide rail 141 to slide the housing 143.

As shown in FIG. 6, in the process of opening the door, the housing 143 on the protruding piece 122 rotates and slides on the guide rail 141 while moving in the direction of the support frame 114. Therefore, the door 120 also rotates through the rotating unit 130 and slides through the roller unit 142 at the same time. Therefore, while the roller unit 142 rotates on the protruding piece 122, the rotational motion of the door is converted into a linear reciprocating motion.

At this time, the hook portion 145 is provided inside the upper frame 112. The hook portion 145 is disposed such that the protruding piece 122 moves along the guide groove 116 and interferes with the outer circumferential surface of the protruding piece 122 while the door 120 is completely opened.

As shown in Fig. 7 (a), the hook portion 145 is hung so that the protruding piece 122 does not return to its original position again. The hook portion 145 is provided with an elastic restoring force that rotates clockwise in the state of FIG. 7(a). In addition, the hook portion 145 includes a second reducer 146 that decelerates the speed while rotating in the forward or reverse rotation direction.

In order to restore the protruding piece 145 back to the original position, as shown in Fig. 7(b), the hook portion 145 is further pushed in the direction of the support frame 116, and then the hook portion 145 is returned to its original position (clockwise rotation). When the interference state of the protruding piece 122 and the hook portion 145 is released before returning to, the protruding piece 122 may be returned in the opposite direction to the support frame 116. In addition, although not shown in the drawing, the rotational force may be applied to the door 120 in the direction of closing the door at all times while not being caught by the hook portion 145.

By providing the hook portion 145 in this way, it is possible to securely maintain the fully opened state of the door 120.

In addition, the sliding movement distance of the projecting piece 122 on the guide groove 116 is about twice as long as the length of the rotating part 130. This is because if the sliding movement distance of the protruding piece 122 is longer or shorter than this, the full opening or closing of the door 120 may not be achieved.

According to the switchgear 100 according to the present invention, first, even when the door has an insufficient open space in the direction of the door of the switchgear, the door can be easily opened and closed, and second, the door's rotational radius is reduced, thereby opening and closing the door. This can be easily made, and third, there is an effect of increasing the working space as the open space of the door is reduced.

In the above, in order to illustrate the technical spirit of the present invention, a specific embodiment has been described with reference to the drawings. It can be carried out within the limits that do not deviate. Therefore, such a modification should also be regarded as belonging to the scope of the present invention, and the true technical protection scope of the present invention should be determined by the technical spirit of the following claims.
