Description

  The present invention relates to a switchboard / distribution panel for supplying power and various signals from power and signal trunk lines to branch circuits on each floor in buildings such as factories and buildings that use large amounts of power. In particular, it relates to the structure of a unitized cubicle (housing).

  For indoor wiring in factories and buildings, for example, high-voltage trunk lines and telephones for supplying power for lighting, power, OA equipment, etc. from the rooftop or basement substation to each floor A low-voltage main line is installed to supply power, and on each floor, the high-voltage main line is connected to the switchboard / distribution panel, and wiring is routed from the branch switch installed on the switchboard / distribution panel to the back of the ceiling or under the floor. In addition to connecting to lighting and a power outlet, a main line for light electrical power is connected to a terminal board, and wiring is performed from the terminal board to a predetermined place through the floor or the like.

  Most of the structure of the switchboard / distribution panel used here is a cubicle (housing) type. In this way, the cubicle type distribution board / distribution board structure that has been widely used in the prior art is a method in which a bare branch bus located above the frame and extending in the horizontal direction is pulled down into the frame, and the branch bus In addition, the power device is mounted on a panel attached to the frame, and a branch cable to be connected to the load side is drawn from the power device such as a breaker, and These frames, panels, and power devices attached on the panels are collectively stored in a cubicle.

  For example, Patent Document 1 discloses a duct in which a socket for inserting and removing a socket is drilled on the back of a square box-shaped unit box, a plurality of unit boxes are connected vertically, and a power bus is stored on the back of the connected unit box. Wiring and mounting devices such as noisy breakers and conductors constituting the distribution board and motor control equipment on the mount blade, project the socket from the back of the mount blade, and put the mount blade in and out of the box freely. A centralized control device is disclosed in which a socket is projected from a hole and connected to a power bus.

  In addition, an opening is formed in the back plate of the rack-mounted distribution unit housing the breaker, and the outlet is fixed inside the housing so that the outlet is exposed from the opening to the back. A hinge is provided at the lower end of the panel to be covered, and is attached so as to be held in a substantially horizontal state when the panel is opened (see Patent Document 2).

  On the other hand, the inside of the housing of the low-voltage switchboard is divided into a device mounting portion consisting of the switchboard main body, a vertical bus room and an external wiring area on both sides thereof, and in the plurality of breaker units on which the breakers are mounted, Panels with a structure where the side terminals are mounted vertically on the device mounting part facing the vertical line room (see Patent Document 3), or the panel base so that the panel base fits in the installation width of the inner wall base material in advance. After adjusting the width of the groundwork and constructing the inner wall ground material, fasten the interior of the board ground to the desired position where the distribution board is to be installed using the fixing means of the wall ground material, and then After adjusting the width of the door base so that it is the same as the width, the inner wall should be secured so that the installation interval of the upper and lower doors corresponds to the height of the door unit to be installed later at the upper and lower positions of the panel base. Using a fixing means for the door base to the base material The distribution board of the mounting method in which to conclude has also been proposed.

However, in many conventional cubicle units, a unified standard case has been mainstreamed by punching and forming the left and right side plates, the back plate and the back opening of the distribution / distribution unit case at the same time, and bending the left and right sides. However, there was a problem that the effective space utilization rate became very bad.
In view of the above-described conventional problems, the present invention makes it possible to assemble an arbitrary cubicle according to the installation location size by extremely simply unitizing the cubicle (casing) of the switchboard / distribution panel. It is an object of the present invention to provide an equipment mounting unit in a cubicle of a switchboard / distribution panel that can improve the effective space utilization rate.

  For this reason, the device mounting unit in the cubicle of the switchboard / distribution panel according to the present invention comprises at least a pair of side plates and a rear window frame plate that connects the pair of side plates at an arbitrary interval. One feature. A second feature is that the at least one pair of side plates and the rear window frame plate are fixed by welding or bolts.

  In particular, in the case of a power distribution system that requires several tens to several hundreds of branch systems, such as a high-rise building in recent years, a large number of cubicles are juxtaposed depending on the branch system, and the distribution panel / distribution panel structure is increasing. It is getting bigger. In particular, even when multiple trunk lines are wired in parallel in the left-right direction, a dead space is created at the construction site because the unit has a constant length in the width direction regardless of the number of branch systems. There's a problem.

The present invention has the following excellent effects.
(1) Since at least a pair of side plates and a rear window frame plate that connects the pair of side plates with an arbitrary interval are used, the unit before assembly is not bulky, It is easy to turn and improves transport efficiency.
(2) By using a rear window frame plate having a desired width for a pair of side plates, a housing having a size according to the installation location can be assembled, and the effective space utilization rate in the cubicle is improved. . That is, a high degree of design freedom can be obtained.

It is a perspective view which shows one Example of the side plate of the apparatus installation unit in a cubicle which concerns on this invention. 1A is a plan view, FIG. 1B is a front view, and FIG. 1C is a right side view of FIG. It is a perspective view which shows the state which attached the back window frame board to the side board of the apparatus installation unit in the cubicle which concerns on this invention. 3A is a plan view, FIG. 3B is a front view, and FIG. 3C is a right side view of FIG.

  Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings.

FIG. 1 to FIG. 4 show main members of a cubicle device mounting unit according to the present invention. The unit body 1 is a conventional method such as welding or bolting a pair of left and right side plates 2 and 2 and a rear window frame plate 3. And a groove portion 5 having an opening 4 on the back side which forms a wiring box in combination with a substantially U-shaped cross section is formed to form a wiring space.
An opening / closing door (not shown) may be attached to the open surface 6 side that is the front of the unit body 1.

  The pair of left and right side plates 2 and 2 and the rear window frame plate 3 are provided with a rack mounting port 7 and a screw hole 8 for mounting a rack member (not shown) for supporting and fixing the high-power main line or the low-power main line. A plurality of holes are formed. In this embodiment, one side plate 2 of the unit main body 1 (the side plate on the right side in the figure which is the front side of the unit 1) is perpendicular to the side plate 2 and has a cover plate 9 fixed over its entire length. The rack plate 9 is also provided with a plurality of rack mounting openings 7. In addition, lip portions 10 that are folded at right angles are formed at the front and rear opening side ends of the side plates 2 and 2 in order to increase the plate strength.

  The side plates 2 and 2 and the rear window frame plate 3 are mainly made of a panel steel material. However, the side plates 2 and 2 and the rear window frame plate 3 may be formed of angle steel only with a frame of the housing, and the panel steel material may be attached to the frame.

  For example, in a construction site where a through-hole is provided in a ceiling-side slab and a floor-side slab, and a high-power main line and a low-power main line are laid through the through-hole and fixed to a rack member (not shown), Since the device mounting unit main body 1 is not a conventional housing shape, a rack member in which a breaker and a number of branch switches are fixed on one panel and attached to both side plates 2, 2 and the rear window frame plate 3 (Not shown), and the structure of the switchboard / distribution panel can be simplified and the manufacturing cost can be reduced.

  Also, when installing electrical equipment units, if the electrical specifications of the floor are not fixed, or if the electrical equipment unit and the switchboard / distribution board manufacturer are different. Normally, the switchboard / distribution panel is often installed later, and a lot of wiring terminals are left unattended until the branch circuit wiring is connected to the branch switch. Is composed of left and right side plates 2 and 2 and a rear window frame plate 3 as an equipment mounting unit 1 in a cubicle, and these components are produced in advance in a factory and assembled at a construction site or after being assembled in a factory. It is carried into the construction site. Therefore, the cubicle device mounting unit configured as described above can be constructed before finishing the construction site.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the claims for utility model registration. For example, the back window frame plate of the present embodiment may be a cross-shaped member that is disposed only above and below the side plate and connects the two. In addition, for example, of course, it can be applied to each floor after placing the slab, and the cubicle units may be stacked in the same manner as the steel frame construction of the building, and then the slab may be placed.
