Abstract

PROBLEM TO BE SOLVED: To solve the problem that it is necessary to perform design in each case of extension and an unnecessary space may be generated by single-surface extension (double-stage stacking) even in the case of extension of only one feeder.SOLUTION: A distribution board comprises: a housing with which a power receiving/distributing apparatus is accommodated within a body of the housing, and which includes a housing cover in an opening in a removable manner; and a bus bar that is electrically connected with the power receiving/distributing apparatus accommodated in the housing. In the distribution board, the bus bar consists of a vertical bus bar and a horizontal bus bar that are disposed in a vertical direction and a horizontal direction with respect to the power receiving/distributing apparatus. Each of the bus bars includes a bus bar conductor. One end of each of the bus bar conductors is formed into a projection and the other end is formed into a recess. The recess and the projection that are formed in the other bus bar conductor can be inserted into and ejected from the projection and the recess. Thus, the multiple bus bar conductors can be electrically connected/disconnected and among the bus bar conductors, the horizontal bus bar conductor is accommodated in a container and supported while being insulated from the horizontal bus bar conductor and making the projection protrude to the outside.SELECTED DRAWING: Figure 1

Description

  Embodiments described herein relate generally to a switchboard that houses power distribution equipment, such as a closed switchboard and a bus.

  As an example of this closed switchboard, there is one that is designed each time it is added.

Utility Model Registration No. 3166213

  The conventional closed switchboard is designed every time it is added, and even if only one feeder is added, it has been expanded to one side (two-tiered), creating unnecessary space.

  The present embodiment has been made in view of the above-mentioned problems. By making the structure of the closed switchboard into a unit (block type) for each feeder, design-less design, simplified board installation planning, and additional feeders can be achieved. A switchboard that can be simplified can be obtained.

  A representative example of the present embodiment includes a housing main body having an opening on at least one surface, a power receiving / distributing device housed inside the housing main body, a housing having a housing lid that can be removed from the opening, and the housing A power distribution board having a bus electrically connected to a power receiving / distributing device housed in the power distribution board, wherein the bus comprises a vertical bus and a horizontal bus arranged in a vertical direction and a horizontal direction with respect to the power receiving / distributing device, Each bus bar includes a bus conductor, and each bus bar conductor has one end formed as a convex part and the other end formed as a concave part, and is formed as another bus conductor in the convex part and the concave part. The concave and convex portions can be inserted / removed so that a plurality of bus conductors can be electrically connected / separated, and among the bus conductors, the horizontal bus conductor is insulated from the horizontal bus conductor. Stored and supported in the container It is a switchboard you are.

  According to the present embodiment, the unitization (block type) for each feeder can be realized, so that it is possible to eliminate the design, simplify the panel installation plan, and simplify the feeder expansion.

  Hereinafter, embodiments will be described with reference to FIGS. 1 to 6. The control panel of this embodiment, for example, a closed switchboard, has a housing main body 1 having an opening 1a on at least one surface, and a power receiving / distribution device such as a drawer type vacuum switch 2 inside the housing main body 1, and the opening 1a A housing 4 having a housing lid 3 that can be removed is provided, and buses 5 and 6 that are electrically connected to the vacuum switch 2 housed in the housing 4.

  The buses 5 and 6 are composed of a vertical bus bar 5 and a horizontal bus bar 6 respectively arranged in the vertical direction and the horizontal direction with respect to the vacuum switch 2, and each bus bar 5 and 6 includes bus bar conductors 7 and 8, respectively. 7 and 8, one end is formed in convex portions 7a and 8a, and the other end is formed in concave portions 7b and 8b. The convex portions 7a and 8a and the concave portions 7b and 8b are formed as separate bus conductors. The formed concave and convex portions can be inserted / removed, whereby a plurality of bus conductors can be electrically connected / separated, and the horizontal bus conductor 6 of the bus conductors is insulated from the horizontal bus conductor. And the convex-shaped part 8a is accommodated and supported in the container 9 in the state which protruded outside.

  The horizontal bus 6 is disposed on the bottom surface of the housing body 1 in the horizontal direction between the board installation surfaces.

The vertical bus 5 constitutes the vertical bus 5, for example, a three-phase bus conductor 7 is disposed vertically on the back side of the vacuum switch 2. A cable 10 for electrically connecting a terminal of the vacuum switch 2 and a load (not shown) is disposed on the side of the vacuum switch 2.
FIG. 7 is a side view showing a configuration corresponding to one feeder, that is, a state where no feeder is added, FIG. 8 is a front view thereof, and FIG. 9 is a front view thereof.

  As described above, the present embodiment is configured by the unitized (blocked) horizontal bus 6 and the unitized (blocked) feeder block having the vacuum switch 2 and the vertical bus 5, so that it is designed for expansion. This makes it possible to reduce the cost, simplify the board layout plan, and simplify the addition of feeders.

  Since the horizontal bus 6 has the bus conductor 8 housed in the container 9, it is isolated in units of blocks even in the event of an accident, for example, burnout, so that it is possible to prevent the influence on other blocks.

  When adding one feeder, the horizontal bus 6 and the vertical bus 5 can be expanded by simply inserting the convex portions of the bus conductors 7 and 8 and the concave portions of the bus conductors 7 and 8 respectively. Become.

  This embodiment has been made to solve the above-described problems, and the design can be made design-less and standardized each time. In addition, since the structure is a block type with one feeder, only one feeder can be added. In addition, it can be added easily because it is a bus insertion connection system.

  In the above-described embodiment, the case where the case lid is configured to be removable from the opening of the case body has been described. However, the present invention is not limited to this. Although the horizontal bus 6 has been described with respect to the embodiment in which the bus conductor 8 is housed in the container 9, the horizontal bus 6 may not be housed in the container 9.
