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

以下、実施の形態について、図１から図６を参照して説明する。本実施形態の制御盤例えば閉鎖配電盤は、少なくとも一方の面に開口部１ａを有する筺体本体１と、筺体本体１の内部に受配電機器例えば引出型真空開閉器２が収納され、開口部１ａに取外し可能に筺体蓋３を有する筺体４と、筺体４内に収納されている真空開閉器２と電気的に接続される母線５、６を備えている。 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.

母線５、６は真空開閉器２に対してそれぞれ垂直方向及び水平方向に配設する垂直母線５及び水平母線６からなり、各母線５、６は母線導体７、８をそれぞれ備え、各母線導体７、８は一端部がそれぞれ凸状部７a、８aに形成され、且つ他端部は凹状部７b、８bに形成され、凸状部７a、８a及び凹状部７b、８bに別の母線導体に形成されている凹状部及び凸状部が挿抜可能で、これにより複数の母線導体が電気的に接離可能となっており、母線導体のうち水平母線導体６はこの水平母線導体とは絶縁され、且つ凸状部８aが外部に突出した状態で容器９内に収納支持されている。 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.

水平母線６は筺体本体１の底面であって盤設置面の間に水平方向に配設されている。 The horizontal bus 6 is disposed on the bottom surface of the housing body 1 in the horizontal direction between the board installation surfaces.

垂直母線５は垂直母線５を構成する例えば三相分の母線導体７は真空開閉器２の背面側に垂直に配設されている。真空開閉器２の側面側に真空開閉器２の端子と負荷（図示しない）を電気的に接続するケーブル１０が配設されている。
図７は１フィーダ分の構成、つまり増設しない状態を示す側面図であり、図８はその正面図であり、図９はその正面図である。 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.

このように本実施形態は、ユニット化（ブロック化）した水平母線６と、ユニット化（ブロック化）した真空開閉器２及び垂直母線５を有するフィーダブロックとで構成したので、増設する際に設計レスとし、コストダウンが可能となり、盤配置計画の簡略化、フィーダ増設の簡略化が可能となる。 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.

水平母線６は、母線導体８が容器９内に収納されているので、万一の事故例えば焼損時にもブロック単位で隔離されているため、他ブロックへの影響も防ぐことが可能となる。 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.

１フィーダ増設する場合は水平母線６及び垂直母線５は、それぞれ有する母線導体７、８の凸状部と、それぞれ有する母線導体７、８の凹状部を、挿入するだけの作業で増設が可能となる。 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.

本実施形態は、上記のような課題を解決するためになされたものであり、都度設計を設計レス化し、標準化ができる。また構造を1フィーダづつのブロック式としているため、１フィーダのみの増設も可能となる。また、母線挿入連結方式なので、簡易に増設できる。 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.

前述の実施形態は、筺体蓋は筺体本体の開口部に取外し可能な構成の場合について説明したが、これにら限らなくてもよい。水平母線６は母線導体８が容器９内に収納された実施形態について説明したが、容器９に収納されないものでもよい。 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.
