的に短絡すゐ。In a variable capacity shunt reactor, a main winding connected to a power line and a secondary winding whose ends are selectively shorted and opened are wound around a main iron core having a gap, and the main winding A configuration in which an intermediate core is provided with a gap between the main winding and the secondary winding has been proposed separately. Figure 1 shows this configuration. Wrap the tightening 3 and secondary volume @ 4, and also this secondary volume @ 4
0. Connect the switch 5 to both ends. 6 is the main winding 5 and the secondary winding @
4, having a gap 7,
Main iron core 1. with 8Fi yoke iron core. Both ends of the intermediate core 60 are magnetically shorted.

存置が増加するしとKなる。In the above configuration, when the switch 5 is opened, the main winding 3
The magnetic flux φ generated by A current flows through the main winding @5J/C, giving a magnetizing ampere-turn corresponding to the magnetoresistance with a magnetoresistance of 7 in parallel. When the switch 5 is closed, the main magnetic flux does not pass through the main core 1, but entirely through the intermediate core 6, and the current that gives the magnetization ampere turns corresponding to the magnetic resistance due to this gap 7 flows through the main winding 13. flows to As a result, the parallel magnetic resistance due to the main iron core 1 is removed, and the magnetic resistance of the magnetic path of the main magnetic flux increases, resulting in a reactor represented by the product of the current flowing through the main IM 3 when the switch 5 is opened. As the number increases, it becomes K.
ところでこのようカ構成を三相線路に使用すると自・は

成が大型化し、又スペースも広くなるといった欠点があ
る。By the way, if such a power configuration is used for a three-phase line, all that is required is to prepare three shunt reactors with the above configuration and install them in parallel.
Since these devices are empty, if three devices are arranged side by side, the overall structure becomes large and the space is also large.
このi明は可変容量型の三相用分路リアクトル、1− 装置の白州化を図ることを目的とする。This item is a variable capacity type three-phase shunt reactor, 1- The purpose is to standardize the equipment.
この発明の1!施例を第2図によって説明する。Part 1 of this invention! An example will be explained with reference to FIG.

Wrap each of the wires 4A to 4C with the 3C12 wire.

璽−り鉄心11 で連結する。Intermediate cores 6A to 6C are arranged between each main winding 3A to 3C and each secondary winding 4A to 4C. These configurations are not much different from the configuration shown in FIG. In the configuration shown in Figure 2, the safety yoke core 8 is extended to the outer periphery of the main winding 3, whereas in the configuration 1! In the hook example, each main core is 1A
The upper ends and lower ends of the intermediate cores 8A to 1C are connected by a twisted iron core 10, and the upper ends and lower ends of the intermediate iron cores 8A to BcO are similarly connected by a twisted iron core 11.
このように構成した場合、開閉器(これは各2次巻線の

的に結合しておけば、各主鉄心及び中間鉄心には所定の
主磁束に発成されるような分流磁束が発生して還流する
とともkそれらのベクトル和は零となる。When configured in this way, the switch (which is connected to both ends of each secondary winding; however, one switch may be shared for each secondary winding) is in an open state. As mentioned above, the main magnetic flux is generated by branching to each main core 1A to 1C and intermediate cores 6A to 60, but in a three-phase line, the main magnetic flux is generated by main cores 1A to 1C branching to intermediate cores 6A to 6C. The vector sum of each is zero and b.If the ends of the main cores 1A to 1COPii are magnetically coupled with the coiled core 10 as shown in the figure, each main core and intermediate core will have a predetermined main magnetic flux. When a shunt magnetic flux is generated and circulated, the vector sum of these fluxes becomes zero.

うKしてもよい。Similarly, when the switch is closed and each secondary winding 15t is short-circuited, magnetic flux is generated in each intermediate core, but
Therefore, the magnetic flux of each intermediate core circulates, and its sum is zero. In other words, regardless of whether the switch is open or closed, the magnetic flux generated in each core is 81
As shown in the figure, even if each core is not magnetically short-circuited with the core 8, reflux can be achieved.
By using fk, there is no iron core extending outside the main 4I@, so it can be made smaller and lighter, and the installation space can be reduced. The embodiment has a structure in which the main winding is placed outside the secondary winding, but on the contrary, as shown in FIG. K may be placed outside.
