Description

[Detailed Description of the Invention] The present invention relates to a capacitor device that combines a capacitor and a series reactor, which is normally connected to a power circuit and used for improving the power factor of a load.

As shown in FIG. 1, a commonly used structure for this type of device is such that a capacitor 1 and a series reactor 2 are three-dimensionally assembled using a frame 3 made of iron or the like.

4 is a cable lead-in duct.

In such a structure, the frame 3 for assembling and drying the capacitor 1 and the series reactor 2 is required, but the series reactor 2 requires bushings for both the power supply side terminal bushing 21 and the container side terminal bushing 22, which makes the equipment difficult to install. It had the disadvantage of being large and expensive.

The present invention has been devised to eliminate the above-mentioned drawbacks, and aims to reduce the number of terminal bushings of a series reactor by omitting the combination frame, thereby providing a compact and inexpensive capacitor device.

That is, by directly connecting the terminal bushing of the container to the series reactor and inserting the terminal bushing of the container into the series reactor, the combination frame and the terminal bushing on the container side of the series reactor are no longer necessary.

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.

In FIG. 2, the capacitor 1 is placed upside down on the top cover 26 of the series reactor 2 so that the terminal bushing 11 of the capacitor faces downward, and the top cover 26 of the series reactor 2 has a perforation 27 at a predetermined position. provided, the perforation part 2
7, the terminal bushing 11 of the capacitor 1 is inserted.

Therefore, since the coil 23 of the series reactor 2 and the terminal bushing 11 of the capacitor 1 are connected within the container of the series reactor 2, a terminal bushing on the capacitor side of the series reactor 2 is not required.

Therefore, the conventional combination frame 3 and capacitor-side terminal bushing 22 of the series reactor 2 are no longer necessary, and the more compact the capacitor device becomes and the lower the equipment cost, the more the terminal bushing drawn out from the capacitor device is Only the power supply side terminal bushing 21 is required, which is extremely advantageous in terms of safety and maintenance.

FIG. 3 shows another embodiment, in which a protruding part 25 is provided in a part of the container of the series reactor 2, and the terminal bushing 11 of the perforated capacitor 1 is inserted into the bottom of the protruding part 25. The coil 23 and the capacitor 1 are connected inside the capacitor 1, and 24 is a capacitor mounting base provided on the container or base of the series reactor 2.

The combination frame and the terminal bushing on the capacitor side of the series reactor 2 are not required, and the same effect as above can be obtained.

The above explanation was about a capacitor device consisting only of a capacitor and a series reactor, but it also includes a switch and a series reactor.
A similar structure can also be applied when incorporating other accessories.

As shown above, the present invention is a condenser device consisting of a series reactor of a capacitor, in which the terminal part of the capacitor is inserted through a hole provided in the top cover of the series reactor or a part of the container, and the capacitor is inserted into the container of the series reactor. It is a capacitor device that connects and integrates a series reactor and a series reactor.It is small, inexpensive, and highly safe, and has great industrial and practical value.
