Description

本発明は、交流電源から複数のモータ駆動コンベヤ等の直流電源変換用に二相を取り出し接続する用途に好適な三相交流電源に対する複数の直流電源の接続方法に関する。   The present invention relates to a method for connecting a plurality of DC power sources to a three-phase AC power source suitable for an application in which two phases are taken out from an AC power source for DC power conversion such as a plurality of motor-driven conveyors.

従来、交流電源を直流に変換する直流電源を搭載した電子機器が開発されている（例えば、特許文献１参照）。
ところで、複数のモータ駆動コンベヤ等の直流電源を接続する場合、三相交流電源を直流電源に変換するには、三相分の配線のうち、任意の二相分の配線から単相交流を取り出して直流に変換する接続方法が採られている。図４は、そのような接続方法を採った従来例を示す図である。この図に示すように、各直流電源２−１、２−２…が三相交流電源１の任意の二相分の配線に接続されている。すなわち、この図では、直流電源２−１、２−２及び２−４がＳ，Ｔ相の配線間に接続されており、直流電源２−３がＲ，Ｓ相の配線間に接続されている。なお、各直流電源２−１、２−２…には負荷３が接続されている。 2. Description of the Related Art Conventionally, electronic devices equipped with a DC power source that converts AC power into DC have been developed (see, for example, Patent Document 1).
By the way, when connecting multiple DC power sources such as motor-driven conveyors, to convert a three-phase AC power source to a DC power source, take out the single-phase AC from any two-phase wiring out of the three-phase wiring. Therefore, a connection method for converting to direct current is adopted. FIG. 4 is a diagram showing a conventional example employing such a connection method. As shown in this figure, each DC power source 2-1, 2-2... Is connected to an arbitrary two-phase wiring of the three-phase AC power source 1. That is, in this figure, the DC power supplies 2-1, 2-2 and 2-4 are connected between the S and T phase wirings, and the DC power supply 2-3 is connected between the R and S phase wirings. Yes. Note that a load 3 is connected to each DC power source 2-1, 2-2.

しかしながら、従来の三相交流電源に対する複数の直流電源の接続方法においては、三相交流電源の各相の位相バランスを考慮せずに、各直流電源を三相交流電源に接続した場合、各相の同期がとれなったりして不安定な交流出力となってしまう問題がある。すなわち、位相バランスを考慮した接続を行うと、図５の（ａ）の交流波形に示すように、Ｔ，Ｓ，Ｒの各相が１２０度の位相差を保って同期がとれた状態になるが、位相バランスを無視した接続を行うと、図５の（ｂ）の交流波形に示すように各相間で位相差が生じ、同期がとれなくなる状態になる。図５の（ｂ）はＴ相がずれた場合であり、Ｔ相とＳ相が６０度の位相差、Ｔ相とＲ相が１８０度の位相差、Ｓ相とＲ相が１２０度の位相差となっている。   However, in the conventional method of connecting a plurality of DC power sources to a three-phase AC power source, each DC power source is connected to a three-phase AC power source without considering the phase balance of each phase of the three-phase AC power source. There is a problem that it becomes unstable AC output due to loss of synchronization. That is, when the connection is performed in consideration of the phase balance, the T, S, and R phases are in synchronization with each other with a phase difference of 120 degrees as shown in the AC waveform in FIG. However, if the connection is performed while ignoring the phase balance, a phase difference occurs between the phases as shown in the AC waveform in FIG. (B) in FIG. 5 shows a case where the T phase is shifted. The phase difference between the T phase and the S phase is 60 degrees, the phase difference between the T phase and the R phase is 180 degrees, and the phase difference between the S phase and the R phase is 120 degrees. It is a phase difference.

本発明は、係る事情に鑑みてなされたものであり、三相交流電源から複数の直流電源変換用に２相を取り出し接続する場合に、三相交流電源の位相バランスを崩すことなく接続することができる三相交流電源に対する複数の直流電源の接続方法を提供することを目的とする。   This invention is made | formed in view of the situation which concerns, and when connecting and taking out two phases for several DC power source conversion from a three-phase alternating current power supply, it connects without destroying the phase balance of a three-phase alternating current power supply. It is an object of the present invention to provide a method for connecting a plurality of DC power sources to a three-phase AC power source capable of performing the above.

本発明の目的は、下記方法により達成される。   The object of the present invention is achieved by the following method.

（１） 三相交流電源に対する複数の直流電源の接続方法であって、三極構造の二つのコネクタ間に三相分の配線のうち二相分をクロスして配線を施し、さらに、クロスした二相分の配線の一方とクロスしなかった残りの一相分の配線に直流電源接続用の配線を接続することを特徴とする。 (1) A method for connecting a plurality of DC power supplies to a three-phase AC power supply, in which two phases of the three-phase wiring are crossed between two connectors of a three-pole structure, and then the wiring is further crossed A DC power supply connection line is connected to the remaining one-phase line that does not cross one of the two-phase lines.

（２） 三相交流電源に代わって単相交流電源を使用する場合に、クロスした前記二相分の配線間を短絡し、この短絡した配線とクロスしなかった前記残りの一相分の配線とを前記単相交流電源に接続することを特徴とする。 (2) When a single-phase AC power supply is used instead of a three-phase AC power supply, the crossed two-phase wiring is short-circuited, and the shorted wiring and the remaining one-phase wiring not crossed Are connected to the single-phase AC power source.

上記（１）に記載の三相交流電源に対する複数の直流電源の接続方法によれば、二つのコネクタ間の配線を三相分のうち二相分をクロスさせるので、この方法による交流電源ケーブルを直流電源の数分だけ用意して連結することで、各直流電源が三相交流電源の異なる二相に交互に接続されることになり、各直流電源が三相交流電源にバランス良く接続されることになる。これにより、三相交流電源の交流波形の位相がずれ難くなり、特に直流電源を二つ以上の偶数個を使用した場合には、完全にバランスがとれるので、三相交流電源の交流波形の位相ずれが略皆無となる。また、この方法による交流電源ケーブルを直流電源の数分だけ用意して、それらをコネクタ接続するだけで済むので、現場の作業が容易になり、作業コストの削減が可能となる。   According to the method for connecting a plurality of DC power sources to the three-phase AC power source described in (1) above, the wiring between the two connectors is crossed for two phases of the three phases. By preparing and connecting as many as the number of DC power supplies, each DC power supply is alternately connected to two different phases of the three-phase AC power supply, and each DC power supply is connected to the three-phase AC power supply in a well-balanced manner. It will be. This makes it difficult for the phase of the AC waveform of the three-phase AC power supply to shift, and especially when two or more DC power supplies are used, it is perfectly balanced, so the phase of the AC waveform of the three-phase AC power supply There is almost no gap. In addition, since AC power cables according to this method are prepared for the number of DC power supplies, and it is only necessary to connect them with connectors, the work at the site is facilitated, and the work cost can be reduced.

上記（２）に記載の三相交流電源に対する複数の直流電源の接続方法によれば、二つのコネクタ間の三相分の配線のうち、クロスさせた二相分の配線を短絡することで、交流電源ケーブルを単相電源用としても使用することができる。   According to the method of connecting a plurality of DC power sources to the three-phase AC power source described in (2) above, by short-circuiting the crossed two-phase wires among the three-phase wires between the two connectors, AC power cables can also be used for single-phase power supplies.

上記（３）に記載の三相交流電源に対する複数の直流電源の接続方法によれば、二つのコネクタ間の配線を、一方のコネクタの配線割付に対して他方を一つずらして配線するので、この方法による交流電源ケーブルを直流電源の数分だけ用意して連結することで、各直流電源が三相交流電源の異なる二相に交互に接続されることになり、各直流電源が三相交流電源にバランス良く接続されることになる。これにより、三相交流電源の交流波形の位相がずれ難くなり、特に直流電源を３の倍数個分使用した場合には、完全にバランスがとれるので、三相交流電源の交流波形の位相ずれが略皆無となる。また、この方法による交流電源ケーブルを直流電源の数分だけ用意して、それらをコネクタ接続するだけで済むので、現場の作業が容易になり、作業コストの削減が可能となる。   According to the method of connecting a plurality of DC power sources to the three-phase AC power source described in (3) above, the wiring between the two connectors is wired by shifting the other one by one with respect to the wiring assignment of one connector.

Almost nothing. In addition, since AC power cables according to this method are prepared for several DC power supplies, and only need to be connected by connectors, field work is facilitated, and work costs can be reduced.

以下、本発明を実施するための好適な実施の形態について、図面を参照して詳細に説明する。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments for carrying out the invention will be described in detail with reference to the drawings.

（実施の形態１）
図１は、本発明の三相交流電源に対する複数の直流電源の接続方法による実施の形態１に係る交流電源ケーブルの概略構成を示す図である。この図において、本実施の形態の交流電源ケーブル１０は、三相交流電源１に接続する一つの直流電源毎に用意されるものであり、三相分の配線１１と、この配線１１の両端夫々に接続される三極構造のコネクタ１２Ａ、１２Ｂと、コネクタ１２Ａの二相分の配線に接続される引き出し線１３とを有して構成されている。 (Embodiment 1)
FIG. 1 is a diagram showing a schematic configuration of an AC power cable according to Embodiment 1 according to a method of connecting a plurality of DC power sources to a three-phase AC power source of the present invention. In this figure, an AC power supply cable 10 according to the present embodiment is prepared for each DC power supply connected to a three-phase AC power supply 1, and includes a three-phase wiring 11 and both ends of the wiring 11. Connector 12A, 12B having a three-pole structure connected to each other, and a lead wire 13 connected to the wiring for two phases of the connector 12A.

二つのコネクタ１２Ａ、１２Ｂ間の配線１１においては、図に示すように三相分のうち二相分の配線１１Ａをクロスさせている。また、コネクタ１２Ａに接続する引き出し線１３の配線においては、クロスした二相分の配線１１Ａのうち一つとクロスさせなかった残りの一つの配線１１Ｂとに接続している。この引き出し線１３には交流を直流に変換する直流電源２が接続される。なお、直流電源２の直流出力端には負荷３が接続される。また、コネクタ１２Ａにはオスピンが装着され、コネクタ１２Ｂにはメスピンが装着されており、複数の交流電源ケーブル１０の連結が可能となっている。   In the wiring 11 between the two connectors 12A and 12B, the wiring 11A for two phases of the three phases is crossed as shown in the figure. In addition, the lead wire 13 connected to the connector 12A is connected to one of the crossed two-phase wires 11A and the remaining one wire 11B that is not crossed. The lead wire 13 is connected to a direct current power source 2 that converts alternating current into direct current. A load 3 is connected to the DC output terminal of the DC power source 2. Further, male pins are attached to the connector 12A, and female pins are attached to the connector 12B, so that a plurality of AC power cables 10 can be connected.

本実施の形態の交流電源ケーブル１０は、上述したように一つの直流電源２に対して一つ使用される。例えば図１に示すように三つの直流電源２を使用する場合は、その数に相当する三つの交流電源ケーブル１０を用意し、それらを連結する。また、交流電源ケーブル１０は、三相交流電源１に接続するためのコネクタ１５を備えている。このコネクタ１５には、交流電源ケーブル１０のコネクタ１２Ａと接続するためにメスピンが装着されている。   One AC power cable 10 of this embodiment is used for one DC power supply 2 as described above. For example, as shown in FIG. 1, when three DC power sources 2 are used, three AC power cables 10 corresponding to the number are prepared and connected. The AC power cable 10 includes a connector 15 for connecting to the three-phase AC power source 1. The connector 15 is fitted with a female pin for connection with the connector 12A of the AC power cable 10.

このような構成の交流電源ケーブル１０において、使用する直流電源２の数だけ接続する場合、まず一つ目の交流電源ケーブル１０のコネクタ１２Ａとコネクタ１５とを接続する。この場合、コネクタ１５に接続された配線の他方の端が三相交流電源１に接続さている。   In the AC power cable 10 having such a configuration, when the same number of DC power sources 2 as the number of DC power sources 2 to be used are connected, the connector 12A and the connector 15 of the first AC power cable 10 are first connected. In this case, the other end of the wiring connected to the connector 15 is connected to the three-phase AC power source 1.

一つ目の交流電源ケーブル１０のコネクタ１２Ａとコネクタ１５とを接続した後、該交流電源ケーブル１０のコネクタ１２Ａの引き出し線１３に一つ目の直流電源２を接続する。次いで、一つ目の交流電源ケーブル１０のコネクタ１２Ｂと二つ目の交流電源ケーブル１０のコネクタ１２Ａとを接続する。そして、二つ目の交流電源ケーブル１０のコネクタ１２Ａの引き出し線１３に二つ目の直流電源２を接続する。次いで、二つ目の交流電源ケーブル１０のコネクタ１２Ｂと三つ目の交流電源ケーブル１０のコネクタ１２Ａとを接続する。その後、三つ目の交流電源ケーブル１０のコネクタ１２Ａの引き出し線１３に三つ目の直流電源２を接続する。   After connecting the connector 12A of the first AC power cable 10 and the connector 15, the first DC power supply 2 is connected to the lead wire 13 of the connector 12A of the AC power cable 10. Next, the connector 12B of the first AC power cable 10 and the connector 12A of the second AC power cable 10 are connected. Then, the second DC power source 2 is connected to the lead wire 13 of the connector 12A of the second AC power cable 10. Next, the connector 12B of the second AC power cable 10 and the connector 12A of the third AC power cable 10 are connected. Thereafter, the third DC power source 2 is connected to the lead wire 13 of the connector 12 </ b> A of the third AC power cable 10.

このように、本実施の形態の交流電源ケーブル１０によれば、二つのコネクタ１２Ａ、１２Ｂ間の配線１１を三相分のうち二相分の配線１１Ａをクロスし、またコネクタ１２Ａに接続する引き出し線１３をクロスした二相分の配線１１Ａのうち一つとクロスさせなかった残りの一つの配線１１Ｂとに接続しているので、直流電源２を複数個使用した場合に、各直流電源２が三相交流電源１の異なる二相に交互に接続されることになり、各直流電源２が三相交流電源１にバランス良く接続されることになる。これにより、三相交流電源１の交流波形の位相がずれ難くなり、特に直流電源２を二つ以上の偶数個を使用した場合には完全にバランスがとれるので、三相交流電源１の交流波形の位相ずれが略皆無となる。また、この交流電源ケーブルを直流電源の数分だけ用意して、それらをコネクタ接続するだけで済むので、現場の作業が容易になり、作業コストの削減が可能となる。   As described above, according to the AC power cable 10 of the present embodiment, the wiring 11 between the two connectors 12A and 12B crosses the wiring 11A for two phases out of the three phases, and is connected to the connector 12A. Since the line 13 is connected to one of the two-phase wirings 11A crossed and the remaining one wiring 11B that is not crossed, when a plurality of DC power supplies 2 are used, each of the DC power supplies 2 has three. The two phases of the AC power source 1 are alternately connected to each other, and the DC power sources 2 are connected to the three-phase AC power source 1 in a balanced manner. This makes it difficult for the phase of the AC waveform of the three-phase AC power source 1 to shift, and particularly when two or more DC power sources 2 are used, a perfect balance is achieved. There is almost no phase shift. Further, since it is only necessary to prepare the AC power cables for the number of DC power supplies and connect them to the connectors, the work at the site is facilitated, and the work cost can be reduced.

なお、上記実施の形態では、三相交流電源１を使用する場合であったが、単相交流電源でもその一相を二相に分配することで、交流電源ケーブル１０をそのまま用いることが可能となる。具体的には、図２に示すように、交流電源ケーブル１０のクロスさせた二相分の配線１１Ａを短絡させる短絡用の配線１６を設けたコネクタ１５Ａを追加して、単相交流電源２０の一相を二相に分配する。これにより、単相交流電源２０でも使用可能となる。因みに、コネクタ１５内で、交流電源ケーブル１０のクロスさせた二相分の配線１１Ａを短絡させる以外に、交流電源ケーブル１０のコネクタ１２Ａ又は１２Ｂのいずれか一方で、クロスさせた二相分の配線１１Ａを短絡させるようにしても構わない。但し、この場合、単相交流電源専用の交流電源ケーブルが必要となり、その分、交流電源ケーブルを２種類用意する必要が出てくる。   In the above embodiment, the three-phase AC power source 1 is used. However, even with a single-phase AC power source, the AC power cable 10 can be used as it is by distributing one phase into two phases. Become. Specifically, as shown in FIG. 2, a connector 15 </ b> A provided with a short-circuit wiring 16 for short-circuiting the cross-phase wiring 11 </ b> A of the AC power supply cable 10 is added to the single-phase AC power supply 20. Distribute one phase into two phases. As a result, the single-phase AC power supply 20 can be used. Incidentally, in the connector 15, in addition to short-circuiting the crossed two-phase wiring 11 </ b> A of the AC power supply cable 10, the crossed two-phase wiring of either the connector 12 </ b> A or 12 </ b> B of the AC power supply cable 10. 11A may be short-circuited. In this case, however, an AC power cable dedicated to the single-phase AC power supply is required, and accordingly, two types of AC power cables need to be prepared.

（実施の形態２）
図３は、本発明の三相交流電源に対する複数の直流電源の接続方法による実施の形態２に係る交流電源ケーブルの概略構成を示す図である。なお、この図において、上述した実施の形態１に係る交流電源ケーブル１０と共通する部分には同じ符号を付けている。本実施の形態の交流電源ケーブル３０は、三極構造の二つのコネクタ１２Ａ、１２Ｂ間に、一方のコネクタ１２Ａの配線割付に対して他方のコネクタ１２Ｂの配線割付を一つずらした三相分の配線１１が接続される。また、三相分の配線１１のうち、任意の二相分に直流電源接続用の引き出し線１３が接続される。 (Embodiment 2)
FIG. 3 is a diagram showing a schematic configuration of an AC power cable according to Embodiment 2 by a method of connecting a plurality of DC power sources to the three-phase AC power source of the present invention. In addition, in this figure, the same code | symbol is attached | subjected to the part which is common in AC power supply cable 10 which concerns on Embodiment 1 mentioned above. The AC power cable 30 according to the present embodiment has a three-phase structure in which the wiring assignment of the other connector 12B is shifted by one with respect to the wiring assignment of the other connector 12A between the two connectors 12A and 12B having a three-pole structure. The wiring 11 is connected. In addition, a lead wire 13 for connecting a DC power source is connected to any two phases of the three-phase wirings 11.

二つのコネクタ１２Ａ、１２Ｂ間の配線１１を、一方のコネクタ１２Ａの配線割付に対して他方のコネクタ１２Ｂを一つずらして配線することで、各直流電源２が三相交流電源１の異なる二相に交互に接続されることになり、各直流電源２が三相交流電源１にバランス良く接続されることになる。   By wiring the wiring 11 between the two connectors 12A and 12B by shifting the other connector 12B by one with respect to the wiring assignment of the one connector 12A, each DC power source 2 is different from the three-phase AC power source 1 in two phases. Thus, the DC power sources 2 are connected to the three-phase AC power source 1 in a balanced manner.

このように、本実施の形態の交流電源ケーブル３０によれば、二つのコネクタ１２Ａ、１２Ｂ間の配線１１を、一方のコネクタ１２Ａの配線割付に対して他方のコネクタ１２Ｂを一つずらして配線するようにしたので、この交流電源ケーブル３０を直流電源２の数分だけ用意して連結することで、各直流電源２が三相交流電源１の異なる二相に交互に接続されることになり、各直流電源２が三相交流電源１にバランス良く接続されることになる。これにより、三相交流電源１の交流波形の位相がずれ難くなり、特に直流電源２を３の倍数個分使用した場合には完全にバランスがとれるので、三相交流電源１の交流波形の位相ずれが略皆無となる。また、この交流電源ケーブル３０を直流電源２の数分だけ用意して、それらをコネクタ接続するだけで済むので、現場の作業が容易になり、作業コストの削減が可能となる。   Thus, according to the AC power cable 30 of the present embodiment, the wiring 11 between the two connectors 12A and 12B is wired by shifting the other connector 12B by one with respect to the wiring assignment of the one connector 12A. Since this is done, by preparing and connecting this AC power cable 30 for the number of DC power supplies 2, each DC power supply 2 is alternately connected to two different phases of the three-phase AC power supply 1. Each DC power source 2 is connected to the three-phase AC power source 1 in a balanced manner. This makes it difficult for the phase of the AC waveform of the three-phase AC power source 1 to shift, and particularly when a DC power source 2 is used in multiples of 3, the phase of the AC waveform of the three-phase AC power source 1 is completely balanced. There is almost no gap. In addition, since the AC power cables 30 are prepared for the number of the DC power supplies 2 and only need to be connected by connectors, the work at the site is facilitated, and the work cost can be reduced.

本発明は、三相交流電源から複数の直流電源変換用に二相を取り出し接続する場合に、三相交流電源の位相バランスを崩すことなく接続することができるといった効果を有し、交流電源を直流に変換する直流電源を搭載した電子機器などへの適用が可能である。   The present invention has the effect that, when two phases are taken out from a three-phase AC power source for conversion to a DC power source and connected, the three-phase AC power source can be connected without losing the phase balance. It can be applied to electronic devices equipped with a DC power source that converts to DC.
