Description
【０００１】[0001]
本考案は、テナントビルにおける各テナントの積算電力計の取付けに好適な分 電盤に関するものである。 The present invention relates to a distribution board suitable for mounting an integrated electricity meter of each tenant in a tenant building.
【０００２】[0002]
一般に、テナントビルにおいては、単相３線式の幹線が接続される分電盤の内 部に、予め、各テナントのための積算電力計用のスペースが確保されているが、 積算電力計の取付けは、分電盤の据付け後、行われるものであり、テナント入居 後に行われることもある。また、積算電力計の取付け後においても、テナントの 入れ替わりや占有面積の変更等に起因する積算電力計の交換や取外し、定期検査 のための積算電力計の着脱交換などが行われる。 Generally, in a tenant building, a space for an integrated wattmeter for each tenant is secured in advance inside the distribution board to which the single-phase three-wire main line is connected. The installation is done after the distribution board is installed, and sometimes after the tenant moves in. Even after the integrated wattmeter has been installed, the integrated wattmeter will be replaced or removed due to tenant replacement or changes in occupied area, and the integrated wattmeter will be removed or replaced for periodic inspections.
【０００３】 ところで、単相３線式の幹線（第１，第２相と中性相とで１００Ｖの電位差を もち、第１相と第２相とで２００Ｖの電位差をもつ交流）が接続される分電盤の 盤内配線は、一般に、第１相を赤、中性相を白、第２相を黒で識別することにな っているが、近年の法的な安全基準（ＪＥＭ）では、盤内配線の色別を電線の端 部のみに施してもよいことになっている。By the way, a single-phase three-wire main line (AC having a potential difference of 100 V between the first and second phases and the neutral phase and an electrical potential difference of 200 V between the first phase and the second phase) is connected. In general, the wiring in the panel of the distribution board is to identify the first phase by red, the neutral phase by white, and the second phase by black, but the recent legal safety standards (JEM) Then, the color of the wiring inside the panel may be applied only to the end of the wire.
【０００４】 このため、現状では、盤内配線の全てに一色（黄色）の電線を使用し、入力端 子台やメインブレーカに接続する電線一端の圧着端子の絶縁カバーとして、赤、 白、黒といった色別の絶縁カバーを使用し、積算電力計に接続する側の電線端部 には、それに対応する色（絶縁カバーと同色）のビニルテープを巻き付けるとい った手段により、識別を行うことが多い。また、これらの電線は、分電盤の内部 に、束ねられて配線されるのが普通であり、分電盤内の電線をたどって両端の色 を確認することは、殆ど不可能に近い状況にある。For this reason, at present, one color (yellow) wire is used for all wiring inside the panel, and red, white, and black are used as the insulation cover of the crimp terminal at one end of the wire connected to the input terminal block or the main breaker. It is possible to identify by a method such as using a different color insulation cover and winding a vinyl tape of the corresponding color (the same color as the insulation cover) around the wire end on the side connected to the integrating wattmeter. Many. In addition, these wires are usually bundled and wired inside the distribution board, and it is almost impossible to trace the wires inside the distribution board and check the colors at both ends. It is in.
【０００５】 従って、例えば、電線にビニルテープを巻き付ける最初の時点で、電線両端の 色を間違えたり、定期検査等のために積算電力計を着脱交換する際、剥がれ落ち たビニルテープを付け間違えたりすると、相の入れ替わりが生じ、これが発見さ れないまま通電されて、事故の原因となる可能性があった。例えば、夜間工事で テナントの積算電力計を取り付ける場合、図１６に示すように、入力端子台ａの 中性相に接続された電線ｂの他端側に「白」であるべきところ「黒」の表示が付 けられ、第２相に接続された電線ｃの他端側に「黒」であるべきところ「白」の 表示が付けられていると、この色表示に従って積算電力計ｄを取り付けることに よって相の入れ替わりＸが生じ、翌朝、メインブレーカｅを投入したとき、１０ ０Ｖ回路であるべき分岐ブレーカｆに２００Ｖが送電されてしまい、１００Ｖ回 路に設けられている種々の電気器具を一瞬にして損傷させることになる。尚、図 中のｇは二次側端子台、ｈは積算電力計用スペース、ｉはブレーカ用スペースを 示す。Therefore, for example, at the first time when the vinyl tape is wound around the electric wire, the color of the both ends of the electric wire may be wrong, or the vinyl tape that has peeled off may be wrongly attached when the integrating wattmeter is detached and replaced for a periodic inspection or the like. Then, the phases were exchanged, and this could be energized without being discovered, causing an accident. For example, when a tenant's watt-hour meter is installed during nighttime construction, as shown in Fig. 16, the place where "white" should be "white" at the other end of the wire b connected to the neutral phase of the input terminal block a is "black". Is attached, and when the other end of the electric wire c connected to the second phase is labeled as “white” where it should be “black”, install the integrated wattmeter d according to this color display. As a result, a phase change X occurred, and when the main breaker e was turned on the next morning, 200V was transmitted to the branch breaker f, which should be a 100V circuit, and various electric appliances installed in the 100V circuit were connected. It will be damaged in an instant. In the figure, g indicates the secondary side terminal block, h indicates the space for the integrated power meter, and i indicates the space for the breaker.

本考案は、上記の現状に鑑みてなされたものであって、その目的とするところ は、積算電力計の取付け前においても、分電盤内にオープン回路がなくて、分電 盤メーカーによる工場での回路チェックが可能であり、分電盤の据付け後、積算 電力計を取り付けるにあたっては、容易に、しかも、各相のつなぎ間違いを生じ ることなく、取り付けることができるようにすることにある。 本考案の他の目的は、積算電力計の製品規格が変わっても、これに対応できる ようにすることにある。 The present invention has been made in view of the above situation, and an object thereof is to provide a factory by a distribution panel manufacturer without an open circuit in the distribution panel even before installation of an integrating wattmeter. It is possible to check the circuit at the time of installation, and after installing the distribution board, when installing the integrating wattmeter, it should be possible to install it easily and without causing connection error of each phase. . Another object of the present invention is to be able to cope with a change in product standard of an integrating wattmeter.

That is, the distribution board with a terminal block for mounting an integrated wattmeter according to the first invention is connected in advance to a predetermined phase between the input terminal block to which the single-phase three-wire main line is connected and the main breaker. An integrating wattmeter with three primary-side terminals and three secondary-side terminals, in which plug-in connection parts corresponding to these terminals are formed, and a short-circuit piece for crossover wiring are selectively inserted and connected. It is characterized by the provision of a terminal block for mounting an integrating wattmeter that is configured as possible.
【０００８】 第２考案による積算電力計取付け用端子台付き分電盤は、単相３線式の幹線が 接続される入力端子台とメインブレーカとの間に、予め所定の相に接続された３ 個の一次側端子と３個の二次側端子とを備え、これらの端子に対応する差込み接 続部が形成された積算電力計取付け用アダプタと渡り配線用短絡ピースとを選択 的に差込み接続可能に構成した積算電力計取付け用端子台を設けた点に特徴があ る。A distribution board with a terminal block for mounting an integrating wattmeter according to a second aspect of the invention is connected in advance to a predetermined phase between an input terminal block to which a single-phase three-wire main line is connected and a main breaker. An adapter for mounting an integrating wattmeter and a short-circuit piece for crossover wiring, each of which has three primary-side terminals and three secondary-side terminals and in which plug-in connections corresponding to these terminals are formed, are selectively inserted.

第１考案の構成によれば、積算電力計の取付け前においては、積算電力計取付 け用端子台に渡り配線用短絡ピースを差込み接続しておき、積算電力計の取付け に際しては、渡り配線用短絡ピースを積算電力計取付け用端子台から抜き取って 、積算電力計を積算電力計取付け用端子台に差込み接続することになる。 According to the configuration of the first invention, before installing the integrating wattmeter, the shorting piece for crossover wiring is inserted and connected to the terminal block for installing the integrating wattmeter, and when installing the integrating wattmeter, the shorting piece for crossover wiring is installed. Remove the short-circuit piece from the terminal block for mounting the integrated wattmeter, and insert the integrated wattmeter into the terminal block for mounting the integrated wattmeter to connect it.
【００１０】 第２考案の構成によれば、積算電力計の取付け前においては、積算電力計取付 け用端子台に渡り配線用短絡ピースを差込み接続しておき、積算電力計の取付け に際しては、渡り配線用短絡ピースを積算電力計取付け用端子台から抜き取って 、積算電力計取付け用アダプタを付け替え、これに積算電力計を差込み接続する ことになる。According to the configuration of the second invention, before installing the integrated wattmeter, the short-circuit piece for wiring is inserted and connected to the terminal block for installing the integrated wattmeter, and when installing the integrated wattmeter, The short-circuit piece for crossover wiring is pulled out from the terminal block for mounting the integrated wattmeter, the adapter for mounting the integrated wattmeter is replaced, and the integrated wattmeter is plugged in and connected.
【００１１】 上記いずれの構成による場合も、積算電力計の取付け前においては、積算電力 計取付け用端子台に渡り配線用短絡ピースを差込み接続しておくことにより、分 電盤内にオープン回路がなくなるので、分電盤メーカーによる工場での回路チェ ックが可能である。In any of the above configurations, before installing the integrated wattmeter, by connecting the short-circuit piece for wiring to the integrated wattmeter installation terminal block and connecting it, an open circuit is formed in the distribution board. Since it disappears, it is possible to check the circuit in the factory by the distribution board manufacturer.
【００１２】 従って、分電盤の据付け後、積算電力計を取り付けるあたっては、渡り配線用 短絡ピースを取り外して積算電力計を差込み接続しさえすれば、必ず、所定の相 に接続されることになり、相のつなぎ間違いが生じる余地がない。また、積算電 力計の取付けも、差込み接続という簡易な手段で行うので、例えば、電線の端部 をビスに巻き付けて締め込むといった一般的な接続手段に比べて、容易に行える ことになる。Therefore, after installing the distribution board, when installing the integrating wattmeter, it is always connected to a predetermined phase if the short-circuit piece for crossover wiring is removed and the integrating wattmeter is plugged in and connected. Therefore, there is no room for misconnection. Also, since the power meter is attached by a simple means such as a plug-in connection, it can be performed more easily than a general connecting means such as winding the end of the wire around a screw and tightening it.

After installing the distribution board, if you install the integrating wattmeter, you only have to remove the shorting wire for crossover wiring and plug in the integrating wattmeter to connect it to the specified phase. There is no room for misconnection. Therefore, it is possible to reliably prevent the occurrence of accidents due to the exchange of phases as described at the beginning, and it is suitable for installing the integrated electricity meter of each tenant in the tenant building. Also, since the watt-hour meter can be attached by a simple means such as plug-in connection, it can be done more easily than, for example, a general connecting means in which the end of the electric wire is wound around a screw and tightened. According to claim 2, even if the product standard of the integrating wattmeter changes, this can be dealt with by using the adapter for installing the integrating wattmeter having the terminal pitch corresponding to it.
