Description

[Detailed description of the invention] This invention relates to a capacitor constructed using a single plate made of ceramic, for example, as a dielectric.
In particular, it concerns the wiring structure.

In order to increase the capacitance of a capacitor, it is necessary to increase the opposing area of the electrodes. If a single plate of ceramic or the like is used as the dielectric material, it is difficult to manufacture a large product, so it may be possible to solve this problem by electrically connecting a plurality of capacitor elements in parallel. Furthermore, in order to create a capacitor with a large capacity and a high voltage, the capacitor elements must be electrically connected in series so that a high voltage is not applied to a single capacitor element.

When a single plate of ceramic or the like is used, the entire structure is stacked in multiple stages, but it is quite difficult to create the above-mentioned large-capacity, high-voltage capacitor structure in such a structure, and the wiring structure is particularly complicated. becomes.

This idea was made in view of the above points, and is an attempt to provide a large-capacity, high-voltage capacitor using a single plate of ceramic or the like as a dielectric.

Furthermore, the present invention aims to provide a capacitor with a simple structure and easy wiring.

The structure of this device is a capacitor made by laminating multiple element single plates with electrodes attached on both sides of the single plate, and fixing them with end terminals arranged on the upper and lower surfaces. A predetermined number of laminated sheets are assembled into an odd number of sets, intermediate terminals are interposed between them, and all non-adjacent terminals consisting of end terminals and intermediate terminals are electrically connected in parallel. It is a capacitor that is connected.

Examples of this invention will be described below in detail with reference to the drawings, but this invention is not limited to the following examples.

Figure 1 shows the overall configuration. 1 is a capacitor element single plate, and this capacitor element single plate 1 is connected to the second capacitor element single plate 1.
As shown in the figure, silver baked electrodes 3 are attached to both sides of a dielectric single ceramic plate 2. 4 is an end terminal, and 5 is an intermediate terminal, each of which is made of a metal wire or the like. In the capacitor, one end terminal 4, a predetermined number of capacitor element single plates 1, an intermediate terminal 5, a predetermined number of capacitor element single plates 1, and an intermediate terminal 5 are stacked and fixed in order from the top, and finally a predetermined number of capacitor elements The other end terminal 4 is attached to the bottom end of the veneer 1.
is configured in a fixed manner. Note that a lead plate 6 is interposed in each stacked fixed portion in consideration of expansion and contraction due to cooling and heating cycles.

One group of the above predetermined number of capacitor element single plates is 5
There are an odd number of sets, and therefore an even number of intermediate terminals 5, 4, are interposed between them. All non-adjacent terminals of all the terminals consisting of the above-mentioned end terminals 4 and intermediate terminals 5 are connected in parallel by two lead wires 7, respectively.

The capacitor thus obtained may be used as a dry capacitor device by providing a molded portion 8 (shown with dotted lines) on the outer periphery by molding, for example.
It may also be used by being housed in a tank-type capacitor device that uses insulating oil or gas.

This idea is structured as described above, so
According to this invention, a large capacitance, high voltage capacitor with a simple structure can be obtained, and in particular, a capacitor with a simple wiring structure can be obtained.

The point that the wiring configuration is simplified will be briefly explained below.

As shown in FIG. 3, if the number of sets a consisting of a predetermined number of element single plates is an even number, one insulator b
must be incorporated, making wiring complicated.

If the number of pairs is odd as in this idea, wiring can be easily done without using insulators.
