Description

[Detailed explanation of the idea] This invention relates to capacitor equipment.

Generally, the size of each component of this type of equipment is limited by transportation issues, so in conventional equipment of this type, for example, three single-phase capacitors 1 are installed as shown in Figure 1. and the series reactor 2 of the three-phase converter connected to these capacitors 1.
are arranged side by side in a plane, and the capacitor 1 and the series reactor 2 are electrically connected via an oil pipe line 3 in which a connecting conductor is housed and sealed.

However, in this configuration, since each device is arranged in a plane, the arrangement area becomes large. Particularly in recent years, as the capacity of this type of equipment increases and the line voltage increases, the above-mentioned trend has become more noticeable, and there is a demand for effective use of space. In FIG. 1, 11 is the oil amount regulator of the condenser 1, 12 is the connection between the capacitor 1 and the oil pipe line 3, 21 is the oil amount regulator of the series reactor 2, and 4 is the connection between the capacitor 1 and the switchgear 5. This is an oil pipe line that connects the two.

This idea was proposed in view of the above-mentioned issues, and a series reactor of a three-phase converter is connected to the capacitors of each single-phase converter via a mounting frame on top of three capacitors of a single-phase converter arranged side by side. At the same time, by electrically connecting the capacitors of each single-phase unit and the series reactor of the three-phase unit via oil pipes that also serve as part of the mounting frame for the reactor of the three-phase unit, this The aim is to reduce the installation area of seed equipment.

An embodiment of this invention will be described below with reference to FIGS. 2 to 4. Note that parts given the same reference numerals as in FIG. 1 indicate the same or corresponding parts. In the illustrated example, a necessary number of mounting frames 6 are provided on the top surface of the container of the capacitor 1 of the V-phase single-phase converter, and the series reactor 2 of the three-phase converter is mounted on the mounting frame 6. Phase reactor series reactor 2
and are electrically connected via an oil pipe line 3.
Note that, of course, the discharge coil may be housed and sealed within the connection portion 12 if necessary.

According to the above configuration, after each device is transported to the site with a size that does not pose a problem due to transportation restrictions, that is, the capacitor is a single-phase device, and the series reactor is a three-phase device, the capacitor 1 of the single-phase device is changed to a three-phase device. A single-phase series reactor 2 is mounted on the top of the capacitor 1, and the capacitor 1 and the series reactor 2 are electrically connected through an oil pipe line 3 to construct this type of equipment three-dimensionally. Therefore, the space above the capacitor 1 can be used effectively and the installation area can be reduced.

Furthermore, since the capacitor 1 of each single-phase converter and the series reactor 2 of the three-phase converter are electrically connected via each separate oil pipe line 3, each oil pipe line 3 can be made compact, and Since the series reactor 2 of the three-phase generator is supported by the mounting frame 6 and each oil pipe line 3, the force applied to the mounting frame 6 and each oil pipe line 3 is dispersed, and the mounting frame 6 and each oil pipe line 3 are not very strong. Nothing is required.

As detailed above, according to this invention, it is possible to downsize this type of equipment with an extremely simple configuration, and it has an extremely practical effect when land is difficult to obtain, as has been the case in recent years.
