This invention relates to a shunt reactor device. A device as shown in FIG. 1 has conventionally been used as a countermeasure against voltage fluctuations in rolling mills, electric trains, etc. where the load fluctuations are relatively slow. In other words, the figure shows only one phase of a three-phase system, where 1 is a step-down transformer and 2 is a step-down transformer.
is a switch using a thyristor or the like, 3 is a capacitor for compensating voltage fluctuations, 4 is a high-voltage winding of a shunt reactor, 5 is a high-voltage bus, 7, 7' is a breaker.
A thyristor is often employed as the switch 2, and since the operating voltage of the thyristor is low, the capacitor 3 is used with its voltage lowered by the step-down transformer 1. Furthermore, when the voltage of the high-voltage bus 5 becomes 60 KV or more, it becomes cost-effective to lower the voltage of not only the thyristor but also the capacitor 3. Note that the high voltage winding 4 of the shunt reactor is connected to the high voltage bus 5 without passing through a transformer. However, this device requires a transformer 1 with the same capacity as the capacitor 3, and also requires a shield, disconnector 7, etc. to protect the transformer 1, and including the shunt reactor 4 increases the number of circuit elements. There were other problems. Therefore, the purpose of this invention is to provide a shunt reactor device that can rationalize the entire device. An embodiment of this invention is shown in FIG. That is, in this shunt reactor device, a low voltage winding 8 is provided in the high voltage winding 4' of the shunt reactor, and a voltage fluctuation compensation capacitor 10 and a switch 11 such as a thyristor are connected to the low voltage winding 8 via a low voltage bus 9. is connected. 12 is a high-voltage bus, 13 is a wire breaker, and 14 is a neutral point. Here, let's assume that the voltage fluctuation adjustment capacity is ±10MVA.
In the case of the conventional example (Fig. 1), the capacity of the high-voltage winding 4 of the shunt reactor is 10MVA, the capacity of the capacitor 3 is 20MVA, and the capacity of the step-down transformer 1 is both the primary and secondary windings. 20MVA is required.
On the other hand, in this embodiment, the capacitance of the high voltage winding 4' of the shunt reactor is 0MVA.
When the delay is 10MVA, capacitor 10 is 10MVA
0MVA when the capacitor 10 is 20MVA, and 10MVA is sufficient when the capacitor 10 is 20MVA, and the low voltage winding 8 of the shunt reactor is equal to the capacitor capacity.
20MVA is required. The following table summarizes the above and compares the winding capacity of the conventional step-down transformer 1 and the shunt reactor of this embodiment.

[Table] As a result, it is clear that the winding capacity of this embodiment is 3/5 that of the conventional example. Also transformer 1
Since this eliminates the need for protection devices such as the shield cutter 7, it is possible to rationalize the protection devices. As described above, according to the shunt reactor device of this invention, the shunt reactor is provided with a low voltage winding, and the capacitor and switch are connected to this.
This has the effect of being able to rationally implement voltage fluctuation countermeasures.
