Description
本発明は、高圧受電設備などに使用され、直列リアクトルと進相コンデンサとを一体化したユニット形コンデンサ装置に関する。
The present invention relates to a unit-type capacitor device that is used in a high-voltage power receiving facility or the like and in which a series reactor and a phase advance capacitor are integrated.
例えば、高圧受電設備などにおいて、受電電力の力率を１００％近くに保持することが望ましい。一般的に、負荷固有の力率は、遅れ電流で６０～７０％程度のものが多いことから、この力率を９５～１００％に改善するために、進み電流を流す進相コンデンサが使用されている。
For example, it is desirable to keep the power factor of the received power close to 100% in a high-voltage power receiving facility. In general, the power factor inherent to the load is often about 60 to 70% as a lag current. Therefore, in order to improve this power factor to 95 to 100%, a phase-advancing capacitor for passing a leading current is used. ing.
一方、近年では負荷の特性が非線形のものが比重を占めるようになり、負荷電流の波形が正弦波から歪む、つまり、負荷電流に含まれる高調波の割合が増加する傾向にある。この高調波の増加により、進相コンデンサが過熱する等の問題が発生することから、その対策として、進相コンデンサに直列リアクトルを接続するようにしている。
On the other hand, in recent years, non-linear load characteristics occupy a specific gravity, and the load current waveform is distorted from a sine wave, that is, the proportion of harmonics included in the load current tends to increase. This increase in harmonics causes problems such as overheating of the phase advance capacitor. As a countermeasure, a series reactor is connected to the phase advance capacitor.
直列リアクトルと進相コンデンサとを一体化したユニット形コンデンサ装置には、進相コンデンサを収納し絶縁油が充填されたコンデンサ容器と、そのコンデンサ容器の上に取り付けられ、直列リアクトルを収納し絶縁油が充填されたリアクトル容器と、コンデンサ容器とリアクトル容器との間に設けられ、進相コンデンサと直列リアクトルとを接続する中間接続部とで構成されたものがある（例えば、特許文献１参照）。
A unit-type capacitor device that integrates a series reactor and a phase-advancing capacitor has a capacitor container that contains a phase-advanced capacitor and is filled with insulating oil, and is mounted on the capacitor container. Is provided between the reactor vessel filled with the capacitor vessel and the reactor vessel and an intermediate connection portion that connects the phase advance capacitor and the series reactor (see, for example, Patent Document 1).
また、他のコンデンサ装置としては、一つのコンデンサ容器内で、上部に直列リアクトル部を、下部に進相コンデンサ部を収容し配置した構造のものがある（例えば、特許文献２参照）。このように、一つのコンデンサ容器に直列リアクトル部と進相コンデンサ部とを収容することにより、直列リアクトルと進相コンデンサとを別体とした場合よりも設置面積を減らし、ブッシング（絶縁碍子）の本数を削減することにより、設置面積およびコストの低減を図るようにしている。
Further, as another capacitor device, there is one having a structure in which a series reactor portion is accommodated in an upper portion and a phase advance capacitor portion is accommodated in a lower portion in one capacitor container (see, for example, Patent Document 2). In this way, by accommodating the series reactor part and the phase advance capacitor part in one capacitor container, the installation area is reduced as compared with the case where the series reactor and the phase advance capacitor are separated, and the bushing (insulator) By reducing the number, the installation area and cost are reduced.
ところで、前述の特許文献１に開示された従来のコンデンサ装置では、コンデンサ容器に進相コンデンサを収納すると共に、リアクトル容器に直列リアクトルを収納した構造、つまり、外部容器を備えた油浸絶縁方式を採用した構造であるため、装置全体が大型化する。コンデンサ容器とそのコンデンサ容器の上に配置されたリアクトル容器との間に、ブッシング（絶縁碍子）等からなる中間接続部が位置することから、装置のコンパクト化を困難にしていた。
By the way, in the conventional capacitor device disclosed in Patent Document 1 described above, a phase advance capacitor is housed in a capacitor container and a series reactor is housed in a reactor container, that is, an oil immersion insulation system having an external container. Since the structure is adopted, the entire apparatus is enlarged. Since the intermediate connection part which consists of bushings (insulator) etc. is located between a capacitor | condenser container and the reactor container arrange | positioned on the capacitor | condenser container, size reduction of the apparatus was made difficult.
また、特許文献２に開示された従来のコンデンサ装置では、直列リアクトルと進相コンデンサとを別体とする場合よりも設置面積を減らし、ブッシングの本数を削減することにより、設置面積およびコストを低減することが可能である。しかしながら、直列リアクトル部および進相コンデンサ部のそれぞれについてコンデンサ容器内で対地絶縁をとる必要があり、装置全体が大型化する。また、直列リアクトル部が進相コンデンサ部と共にコンデンサ容器に収容した構造であることから、直列リアクトル部の放熱構造を必要とするためにも装置全体が大型化するという問題があった。
Further, in the conventional capacitor device disclosed in Patent Document 2, the installation area and cost are reduced by reducing the installation area and the number of bushings compared to the case where the series reactor and the phase advance capacitor are separated. Is possible. However, it is necessary to provide ground insulation in the capacitor container for each of the series reactor portion and the phase advance capacitor portion, which increases the size of the entire device. In addition, since the series reactor part has a structure in which the series reactor part is housed in the capacitor container together with the phase-advancing capacitor part, there is a problem that the entire apparatus is increased in size because the heat dissipation structure of the series reactor part is required.
そこで、本発明は前述した問題点に鑑みて提案されたもので、その目的とするところは、装置全体の小型化およびコストを低減することができるユニット形コンデンサ装置を提供することにある。
Therefore, the present invention has been proposed in view of the above-described problems, and an object of the present invention is to provide a unit-type capacitor device that can reduce the size and cost of the entire device.
前述の目的を達成するための技術的手段として、本発明は、直列リアクトルと進相コンデンサとを一体化したユニット形コンデンサ装置であって、直列リアクトルを支持体で保持し、その支持体の直列リアクトルの下方に位置する枠部の内部に、コンデンサ素子を樹脂でモールドした進相コンデンサを収容したことを特徴とする。
As technical means for achieving the above-mentioned object, the present invention is a unit-type capacitor device in which a series reactor and a phase advance capacitor are integrated, the series reactor is held by a support, and the support is connected in series. A phase advance capacitor in which a capacitor element is molded with a resin is housed inside a frame portion located below the reactor.
本発明では、直列リアクトルの支持体の枠部の内部に、コンデンサ素子を樹脂でモールドした進相コンデンサを収容した構造を採用したことにより、従来のような外部容器を持たない構造であることから、装置全体のコンパクト化が実現容易である。なお、外部容器を備えた油浸絶縁方式を採用しない完全な乾式であるため、油漏れの懸念がない。
In the present invention, by adopting a structure in which a phase advance capacitor in which a capacitor element is molded with a resin is accommodated inside the frame portion of the support body of the series reactor, the structure does not have a conventional external container. Therefore, it is easy to make the entire apparatus compact. In addition, since it is a complete dry type that does not employ an oil immersion insulation method with an external container, there is no concern of oil leakage.
本発明において、直列リアクトルと進相コンデンサとの電気的接続は、コンデンサ素子と電気的に接続された絶縁被覆電線を進相コンデンサの外装モールド部から導出し、その導出された絶縁被覆電線の先端部を直列リアクトルの端子部に接続した構造が望ましい。このような接続構造を採用すれば、進相コンデンサの端子部としてブッシング（絶縁碍子）が不要となることから、ブッシングの本数を削減できてコスト低減が図れる。
In the present invention, the electrical connection between the series reactor and the phase advance capacitor is derived from the insulation-molded electric wire electrically connected to the capacitor element from the outer mold part of the phase advance capacitor, and the leading end of the derived insulation-coated electric wire. The structure which connected the part to the terminal part of the series reactor is desirable. By adopting such a connection structure, a bushing (insulator) is not required as the terminal portion of the phase advance capacitor, so that the number of bushings can be reduced and the cost can be reduced.
本発明における進相コンデンサは、コンデンサ素子の樹脂モールド後に支持体の枠部に挿入されているか、あるいは、コンデンサ素子を支持体の枠部で樹脂モールドされていることが望ましい。前者の場合、コンデンサ素子を樹脂でモールドすることにより進相コンデンサを製作し、その製作後に進相コンデンサを直列リアクトルの支持体の枠部に組み付ける。また、後者の場合、直列リアクトルの支持体の枠部を金型として利用し、その支持体の枠部でコンデンサ素子を樹脂モールドすることにより、進相コンデンサの製作と組み付けを同時に行う。
The phase advance capacitor in the present invention is preferably inserted into the support frame after resin molding of the capacitor element, or the capacitor element is preferably resin molded in the support frame. In the former case, the phase advance capacitor is manufactured by molding the capacitor element with resin, and after the manufacture, the phase advance capacitor is assembled to the frame portion of the support body of the series reactor. In the latter case, the phase-reacting capacitor is manufactured and assembled at the same time by using the frame portion of the support body of the series reactor as a mold and resin molding the capacitor element with the frame portion of the support body.
本発明によれば、直列リアクトルを支持体で保持し、その支持体の直列リアクトルの下方に位置する枠部の内部に、コンデンサ素子を樹脂でモールドした進相コンデンサを収容した構造を採用したことにより、従来のような外部容器を持たない構造であることから、装置全体のコンパクト化が実現容易である。このように、装置全体のコンパクト化により、このコンデンサ装置を高圧受電設備の受電盤内に収納するに際してもスペースの制約を受けることなく、受電盤内への設置も容易となってその実用的価値も大きい。
According to the present invention, a structure is adopted in which a series reactor is held by a support, and a phase advance capacitor in which a capacitor element is molded with a resin is contained inside a frame portion located below the series reactor of the support. Therefore, since the structure does not have an external container as in the prior art, it is easy to realize a compact apparatus as a whole. Thus, by making the entire device compact, the capacitor device can be easily installed in the power receiving panel without being limited in space even when it is housed in the power receiving panel of the high voltage power receiving equipment, and its practical value. Is also big.
本発明に係るユニット形コンデンサ装置の実施形態を以下に詳述する。なお、以下の実施形態では、高圧受電設備などに使用され、直列リアクトルと進相コンデンサとを一体化したユニット形コンデンサ装置を例示する。
Embodiments of a unit type capacitor device according to the present invention will be described in detail below. In the following embodiment, a unit type capacitor device that is used in a high-voltage power receiving facility or the like and in which a series reactor and a phase advance capacitor are integrated will be exemplified.
本実施形態に係るユニット形コンデンサ装置は、図１および図２に示すように、環状のコイル部１の中央に鉄心部２を貫通させた直列リアクトル３と、コンデンサ素子（図示せず）を樹脂でモールドした進相コンデンサ４とを一体化し、直列リアクトル３を保持する支持体５を備えている。この支持体５は、直列リアクトル３の鉄心部２の上部に取り付けられた断面Ｌ字状の上取付部６と、直列リアクトル３の鉄心部２の下部に取り付けられた断面略Ｕ字状の下取付部７と、直列リアクトル３の下方に位置し、直列リアクトル３の下取付部７が固定された枠部８とで構成されている。この直列リアクトル３の下方に位置する枠部８の内部に進相コンデンサ４を収容する。
As shown in FIGS. 1 and 2, the unit-type capacitor device according to the present embodiment includes a series reactor 3 in which an iron core portion 2 is passed through the center of an annular coil portion 1, and a capacitor element (not shown) as a resin. And a support 5 for holding the series reactor 3. The support 5 includes an upper mounting portion 6 having an L-shaped cross section attached to the upper portion of the core portion 2 of the series reactor 3, and a lower U-shaped cross section attached to the lower portion of the core portion 2 of the series reactor 3. It is comprised by the attaching part 7 and the frame part 8 which is located under the serial reactor 3 and the lower attaching part 7 of the serial reactor 3 was fixed. The phase-advancing capacitor 4 is housed inside the frame portion 8 located below the series reactor 3.
本実施形態に係るユニット形コンデンサ装置は、枠部８の内部に進相コンデンサ４を収容した構造を採用したことにより、従来のような外部容器を持たない構造であることから、装置全体のコンパクト化が実現容易となる。なお、外部容器を備えた油浸絶縁方式を採用しない完全な乾式であるため、油漏れの懸念がない。このように、装置全体のコンパクト化により、このコンデンサ装置を高圧受電設備の受電盤内に収納するに際してもスペースの制約を受けることなく、受電盤内への設置も容易となってその実用的価値も大きい。また、直列リアクトル３は、支持体５の下取付部７で進相コンデンサ４と一体化することにより露呈した構造となっているので放熱し易く、その直列リアクトル３の発熱が進相コンデンサ４に影響することも抑制できる。
The unit-type capacitor device according to the present embodiment employs a structure in which the phase advance capacitor 4 is accommodated inside the frame portion 8, and thus has a conventional structure without an external container. Can be easily realized. In addition, since it is a complete dry type that does not employ an oil immersion insulation method with an external container, there is no concern of oil leakage. Thus, by making the entire device compact, the capacitor device can be easily installed in the power receiving panel without being limited in space even when it is housed in the power receiving panel of the high voltage power receiving equipment, and its practical value.

Further, since the series reactor 3 has a structure that is exposed by being integrated with the phase advance capacitor 4 at the lower mounting portion 7 of the support 5, it is easy to radiate heat, and the heat generated by the series reactor 3 is transferred to the phase advance capacitor 4. Influencing can also be suppressed.
直列リアクトル３と進相コンデンサ４との電気的接続は、コンデンサ素子と電気的に接続された絶縁被覆電線９を進相コンデンサ４の外装モールド部１０から導出し、その導出された絶縁被覆電線９の先端部を、直列リアクトル３のコイル部１に設けられた端子部１１に接続する。なお、進相コンデンサ４の外装モールド部１０から絶縁被覆電線９を導出するため、枠部８の対応部位には絶縁被覆電線９を挿通させる開口部１２が設けられている。この絶縁被覆電線９は、コンデンサ素子を樹脂でモールドする進相コンデンサ４の製作時に、コンデンサ素子と電気的に接続しておく。図２の符号１３は、コンデンサ装置を系統に接続するために、直列リアクトル３のコイル部１の端子部１４に接続された引き出し電線である。

本実施形態に係るユニット形コンデンサ装置は、コンデンサ素子と電気的に接続された絶縁被覆電線９を進相コンデンサ４の外装モールド部１０から導出し、その絶縁被覆電線９の先端部を直列リアクトル３の端子部１１に接続した構造を採用したことにより、進相コンデンサ４の端子部としてブッシング（絶縁碍子）が不要となることから、ブッシングの本数を削減できてコスト低減が図れる。また、進相コンデンサ４の外装モールド部１０から絶縁被覆電線９を導出していることから、充電部が露出することはない。
In the unit-type capacitor device according to the present embodiment, the insulated coated electric wire 9 electrically connected to the capacitor element is led out from the exterior mold portion 10 of the phase advance capacitor 4, and the tip of the insulated coated electric wire 9 is connected to the series reactor 3. By adopting the structure connected to the terminal portion 11, no bushing (insulator) is required as the terminal portion of the phase-advancing capacitor 4, so the number of bushings can be reduced and the cost can be reduced. Moreover, since the insulation coating electric wire 9 is derived | led-out from the exterior mold part 10 of the phase advance capacitor 4, a charging part is not exposed.
前述した進相コンデンサ４は、以下の第一の手段および第二の手段により、支持体５の枠部８の内部に収容される。
The aforementioned phase advance capacitor 4 is accommodated inside the frame portion 8 of the support 5 by the following first means and second means.
まず、第一の手段としては、図３に示すように、コンデンサ素子を樹脂でモールドした後、その樹脂モールドにより製作された進相コンデンサ４を支持体５の枠部８の内部に挿入配置する。つまり、コンデンサ素子を樹脂でモールドすることにより進相コンデンサ４を製作し、その製作後に進相コンデンサ４を直列リアクトル３の支持体５の枠部８に組み付ける。この構造の場合、進相コンデンサ４と枠部８とは別体であるため、その進相コンデンサ４の外装モールド部１０と枠部８の内周面との間には若干の隙間ｔが形成される。

In this structure, since the phase advance capacitor 4 and the frame portion 8 are separate bodies, a slight gap t is formed between the exterior mold portion 10 of the phase advance capacitor 4 and the inner peripheral surface of the frame portion 8. Is done.
第二の手段としては、図４に示すように、コンデンサ素子を支持体５の枠部８で樹脂モールドすることにより進相コンデンサ４を製作する。つまり、支持体５の枠部８を金型として利用し、その枠部８でコンデンサ素子を樹脂モールドすることにより、進相コンデンサ４の製作と組み付けを同時に行う。この構造の場合、進相コンデンサ４と枠部８とは一体物になるため、その進相コンデンサ４の外装モールド部１０と枠部８の内周面との間は、隙間が存在せずに密着した状態となる。
As a second means, as shown in FIG. 4, the phase advance capacitor 4 is manufactured by resin-molding the capacitor element with the frame portion 8 of the support 5. That is, by using the frame portion 8 of the support 5 as a mold and resin molding the capacitor element with the frame portion 8, the phase advance capacitor 4 is manufactured and assembled at the same time. In the case of this structure, the phase advance capacitor 4 and the frame portion 8 are integrated, so that there is no gap between the exterior mold portion 10 of the phase advance capacitor 4 and the inner peripheral surface of the frame portion 8. It will be in close contact.
