この発明は三相用可変容量型分路リアクトル装
置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a three-phase variable capacitance shunt reactor device.
可変容量型分路リアクトルにおいて、ギヤツプ
を有する主鉄心に、電力線路に接続される主巻線
と、両端が選択的に短絡開放される２次巻線とを
巻装し、又前記主巻線と２次巻線との間にギヤツ
プを有する中間鉄心を設けた構成は別途提案され
ているところである。第１図はその構成を示し、
１はギヤツプ２を存する主鉄心で、これに主巻線
３及び２次巻線４を巻装し、又この２次巻線４の
両端に開閉器５を接続する。６は主巻線３と２次
巻線４との間に配置された中間鉄心で、ギヤツプ
７を有し、８はヨーク鉄心で主鉄心１、中間鉄心
６の両端を磁気的に短絡する。 In a variable capacity shunt reactor, a main winding connected to a power line and a secondary winding whose ends are selectively short-circuited and opened are wound around a main iron core having a gap, and the main winding A configuration in which an intermediate core having a gap is provided between the core and the secondary winding has been proposed separately. Figure 1 shows its configuration,
Reference numeral 1 denotes a main iron core having a gap 2, around which a main winding 3 and a secondary winding 4 are wound, and a switch 5 is connected to both ends of the secondary winding 4. 6 is an intermediate core disposed between the main winding 3 and the secondary winding 4, and has a gap 7; 8 is a yoke core that magnetically short-circuits both ends of the main core 1 and the intermediate core 6.
以上の構成において開閉器５を開放した場合は
主巻線３によつて発生する磁束φは主鉄心１及び
中間鉄心６に分流し、これが合流してヨーク鉄心
８を経て還流し、これによつて主鉄心１のギヤツ
プ２による磁気抵抗と中間鉄心６のギヤツプ７に
よる磁気抵抗が並列に存在する磁気抵抗に相当す
る磁化アンペアターンを与える電流が主巻線３に
流れる。又開閉器５を閉成した場合は前記主磁束
は主鉄心１を通らず、すべて中間鉄心６を通るよ
うになり、このギヤツプ７による磁気抵抗に相当
する磁化アンペアターンを与える電流が主巻線３
に流れる。したがつて前記主鉄心１による並列磁
気抵抗が除かれるため主磁束φの磁路の磁気抵抗
が増し、開閉器５の開路により主巻線３に流れる
電流との積で表わされるリアクトル容量が増加す
ることになる。 In the above configuration, when the switch 5 is opened, the magnetic flux φ generated by the main winding 3 is divided into the main iron core 1 and the intermediate iron core 6, which join together and return through the yoke iron core 8. A current flows through the main winding 3 to provide a magnetizing ampere turn corresponding to the magnetic resistance in which the magnetic resistance due to the gap 2 of the main core 1 and the magnetic resistance due to the gap 7 of the intermediate core 6 exist in parallel. When the switch 5 is closed, the main magnetic flux does not pass through the main iron core 1, but all passes through the intermediate iron core 6, and the current that gives the magnetization ampere turns corresponding to the magnetic resistance due to the gap 7 flows through the main winding. 3
flows to Therefore, since the parallel magnetic resistance caused by the main iron core 1 is removed, the magnetic resistance of the magnetic path of the main magnetic flux φ increases, and when the switch 5 is opened, the reactor capacity, which is expressed as the product of the current flowing through the main winding 3, increases. I will do it.
ところでこのような構成を三相線路に使用する
ときは、上記構成の分路リアクトルを３台用意し
これを並設すればよいのであるが、主巻線３の外
側にヨーク鉄心８が突出されるので、３台並置し
た場合にはその全体の構成が大型化し、又スペー
スも広くなるといつた欠点がある。 By the way, when such a configuration is used for a three-phase line, it is sufficient to prepare three shunt reactors with the above configuration and install them in parallel, but the yoke core 8 protrudes outside the main winding 3. Therefore, when three devices are arranged side by side, the overall structure becomes large and the space becomes large, which is a drawback.
この発明は可変容量型の三相用分路リアクトル
装置の小型化を図ることを目的とする。 The object of the present invention is to reduce the size of a variable capacity three-phase shunt reactor device.
この発明の実施例を第２図によつて説明する。
Ａ〜Ｃは第１図の構成と原理的には同じの分路リ
アクトルを示し、それぞれ主鉄心１Ａ〜１Ｃ、中
間鉄心６Ａ〜６Ｃ、主巻線３Ａ〜３Ｃ及び２次巻
線４Ａ〜４Ｃを備え、主鉄心１Ａ〜１Ｃのそれぞ

れぞれを巻装する。各主巻線３Ａ〜３Ｃと２次巻
線４Ａ〜４Ｃとの間にそれぞれ中間鉄心６Ａ〜６
Ｃのそれぞれが配置される。 An embodiment of this invention will be explained with reference to FIG.
A to C indicate shunt reactors that are basically the same in configuration as the one shown in FIG. The main windings 3A to 3C and the secondary windings 4A to 4C are wound around the main cores 1A to 1C, respectively. Between each main winding 3A to 3C and the secondary winding 4A to 4C, intermediate iron cores 6A to 6 are provided.
C are arranged.
これらの構成は第１図の構成と大差はないが、
第１図の構成ではヨーク鉄心８を主巻線３の外周
側に延長して配置するのに対し、第２図の実施例

ク鉄心１０で連結し、及び中間鉄心８Ａ〜８Ｃの
上端間及び下端間を同じようにヨーク鉄心１１で
連結する。 These configurations are not much different from the configuration in Figure 1, but
In the configuration shown in FIG. 1, the yoke core 8 is arranged extending to the outer circumferential side of the main winding 3, whereas in the embodiment shown in FIG. The upper ends and lower ends of the intermediate cores 8A to 8C are similarly connected by a yoke core 11.
このように構成した場合、開閉器（これは各２

線につきひとつの開閉器を共用するようにしても
よい。）を開放した状態では、前述のように各主
鉄心１Ａ〜１Ｃ及び中間鉄心６Ａ〜６Ｃに主磁束
が分流して発生するが、三相線路ではこの主鉄心
１Ａ〜１Ｃが中間鉄心６Ａ〜６Ｃを分流する主磁
束のベクトル和はそれぞれ零であるから図のよう

は所定の主磁束に分成されるような分流磁束が発
生して還流するとともにそれらのベクトル和は零
となる。 When configured in this way, the switch
It is connected to both ends of the next winding. However, one switch may be shared for each secondary winding. ) is open, the main magnetic flux is divided into the main cores 1A to 1C and the intermediate cores 6A to 6C as described above, but in a three-phase line, the main cores 1A to 1C are divided into the intermediate cores 6A to 6C. Since the vector sum of the main magnetic flux that divides each of A shunt magnetic flux that is divided into magnetic fluxes is generated and circulated, and their vector sum becomes zero.
同じように開閉器を閉成して各２次巻線を短絡
した場合は各中間鉄心に磁束が発生するが、ヨー
ク鉄心１１で連結されているので、各中間鉄心の
磁束は還流し、かつそのベクトル和は零である。
すなわち開閉器が開放、閉成の如何を問わず、各
鉄心に発生する磁束は第１図に示すようなヨーク
鉄心８で各鉄心を磁気的に短絡しなくとも、還流
するようになる。そしてヨーク鉄心８を使用しな
いですむことにより、主巻線の外側に延長する鉄
心がなくそれだけ小型に製作でき、かつ軽量化も
可能となり、設置スペースの縮少も図ることがで
きる。 Similarly, if the switch is closed and each secondary winding is short-circuited, magnetic flux will be generated in each intermediate core, but since they are connected by the yoke core 11, the magnetic flux of each intermediate core will return and The vector sum is zero.
That is, regardless of whether the switch is open or closed, the magnetic flux generated in each core will circulate without magnetically short-circuiting each core with the yoke core 8 as shown in FIG. By not using the yoke core 8, there is no core extending to the outside of the main winding, so the device can be made smaller and lighter, and the installation space can be reduced.
以上の実施例は主巻線を２次巻線の外側に配置
した構成としているが、これとは逆に第４図に示
すように２次巻線４Ａ〜４Ｃを主巻線３Ａ〜３Ｃ
の外側に配置するようにしてもよい。 The above embodiment has a structure in which the main winding is arranged outside the secondary winding, but on the contrary, as shown in FIG.
It may also be placed outside the .

置スペースの縮少化が期待できるといつた効果を
奏する。 As explained in detail above, this invention is applicable when three variable capacity shunt reactors are used for three-phase operation.
The structure can be made smaller and lighter, and the installation space can be expected to be reduced.
