Description

本発明は、変圧器、リアクトル等の静止誘導機器に関し、特に静止誘導機器から独立した電源が必要な、若しくは独立した電源を有する方が好ましい静止誘導機器に関する。 The present invention relates to a static induction device such as a transformer and a reactor, and more particularly to a static induction device that requires a power source independent of the static induction device or preferably has an independent power source.

静止誘導機器、例えば変圧器において、変圧器による電源供給以外にも付属装置などの他の装置用に独立した電源を必要とする場合がある。例えば特許文献１では、柱上変圧器が受電する系統電圧や、需要家に配電する電力量をセンサにより計測し、その信号を逐次有線、無線通信手段により送信し、電力系統の高精度な監視、維持を実現する技術が開示されている。 Static induction devices, such as transformers, may require a separate power source for other devices, such as ancillary devices, in addition to the power supply by the transformer. For example, in Patent Document 1, the system voltage received by the pole transformer and the amount of power distributed to the consumer are measured by a sensor, and the signals are sequentially transmitted by wired and wireless communication means to monitor the power system with high accuracy. , The technology to realize maintenance is disclosed.

米国特許第９２６３１８２号明細書U.S. Pat. No. 9,263,182

静止誘導機器、例えば変圧器において、変圧器による電源供給以外にも付属装置などの他の装置用に独立した電源を必要とする場合がある。その場合、他機器や電源から電源供給する方法が考えられるが、近くに適当な機器や電源があるとは限らない。変圧器の二次側から直接電源を供給する方法が考えられるが、この電源は変圧器の二次側を直接利用しているため保護が困難であり、また、使用電力分だけ本来二次側から使用する電力容量が少なくなる。また、変圧器鉄心に三次巻線を設け、一次巻線、二次巻線から独立した電源を設けることは可能であるが、三次巻線を設けるために鉄心を専用に設計する必要がある。また、鉄心の断面積を変えず、鉄心、脚部、ヨーク部を長くした場合鉄心の磁路長が増大し、鉄損が増大する。 Static induction devices, such as transformers, may require a separate power source for other devices, such as ancillary devices, in addition to the power supply by the transformer. In that case, a method of supplying power from another device or power source can be considered, but there is not always a suitable device or power source nearby. A method of supplying power directly from the secondary side of the transformer can be considered, but this power supply is difficult to protect because it directly uses the secondary side of the transformer, and the power used is originally the secondary side. Uses less power capacity. Further, although it is possible to provide a tertiary winding on the transformer core and provide a power supply independent of the primary winding and the secondary winding, it is necessary to design the iron core exclusively for providing the tertiary winding. Further, when the iron core, the leg portion, and the yoke portion are lengthened without changing the cross-sectional area of the iron core, the magnetic path length of the iron core increases and the iron loss increases.

特許文献１には、柱状変圧器にセンサ手段や通信手段を設けることが開示されているが、それらの具体的な電源の供給方法は記載されていない。 Patent Document 1 discloses that a columnar transformer is provided with sensor means and communication means, but does not describe a specific power supply method for them.

本発明は、静止誘導機器の付属装置などの他の装置を動作させるための電源を、静止誘導機器の構成を大幅に変更することなく、静止誘導機器自体から低コストで安全に供給することを目的とする。 The present invention makes it possible to safely supply power for operating other devices such as an accessory device of a static guidance device from the static guidance device itself at low cost without significantly changing the configuration of the static guidance device. The purpose.

It is a stationary induction device having a main iron core and a main winding wound around the main iron core, and includes a power source generating means for generating a power source for the device. The power supply winding is wound around the iron core, and the power supply core is installed so that a part of the magnetic flux of the main core flows.

図１および図２に、本発明の静止誘導機器の概念図を示す。図１は、単相変圧器を例とした本発明の概念図を、図２は、三相変圧器を例とした本発明の概念図を示す。本発明は、電源生成手段により、三次巻線を設けていない主鉄心に後付けで磁束の流れを作り、その新しく作った磁束を利用して三次巻線から独立した電源を供給する。磁束の流れを作る方法としては、主鉄心と同様のまたは異なる磁性材料から成る電源用鉄心を主鉄心に取り付ける。ただし、主鉄心、もしくは取り付ける電源用鉄心に絶縁被膜がないと、主鉄心と電源用鉄心間が絶縁されていない場合は、局所過熱により損失が発生する恐れがあるため、絶縁物を間に挟む。 1 and 2 show a conceptual diagram of the stationary induction device of the present invention. FIG. 1 shows a conceptual diagram of the present invention using a single-phase transformer as an example, and FIG. 2 shows a conceptual diagram of the present invention using a three-phase transformer as an example. According to the present invention, a magnetic flux flow is retrofitted to a main iron core not provided with a tertiary winding by a power generation means, and the newly created magnetic flux is used to supply a power source independent of the tertiary winding. As a method of creating the flow of magnetic flux, a power core made of the same or different magnetic material as the main core is attached to the main core. However, if the main iron core or the power supply core to be attached does not have an insulating coating, if the main iron core and the power supply core are not insulated, loss may occur due to local overheating, so an insulator is sandwiched between them. ..

図１において、単相変圧器は矩形状の主鉄心１と、主鉄心１に巻き回した２つの主巻線２から構成されており、主鉄心１の一部に電源生成手段１０が取り付けられている。電源生成手段１０は、コ字状の電源用鉄心１１と、それに巻き回した電源用巻線１２から構成され、電源用鉄心１１は主鉄心１の磁束の一部が流れるように主鉄心１に取り付けられる。 In FIG. 1, a single-phase transformer is composed of a rectangular main core 1 and two main windings 2 wound around the main core 1, and a power generation means 10 is attached to a part of the main core 1. ing. The power supply generating means 10 is composed of a U-shaped power supply core 11 and a power supply winding 12 wound around the power supply core 11, and the power supply core 11 is formed in the main core 1 so that a part of the magnetic flux of the main core 1 flows. It is attached.

図２において、三相変圧器は、主鉄心を構成する２つの矩形状の内側鉄心１ａおよび内側鉄心を取り囲む外側鉄心１ｂと、内側鉄心１ａと外側鉄心１ｂの３つの脚部に巻き回した３つの主巻線２ａから構成されており、外側鉄心１ｂの一部に電源生成手段１０が取り付けられている。電源生成手段１０は、コ字状の電源用鉄心１１と、それに巻き回した電源用巻線１２から構成され、電源用鉄心１１は外側鉄心１ｂの磁束の一部が流れるように取り付けられる。 In FIG. 2, the three-phase transformer is wound around the two rectangular inner cores 1a constituting the main core, the outer core 1b surrounding the inner core, and the three legs of the inner core 1a and the outer core 1b3. It is composed of two main windings 2a, and a power generation means 10 is attached to a part of the outer iron core 1b. The power supply generating means 10 is composed of a U-shaped power supply core 11 and a power supply winding 12 wound around the power supply core 11, and the power supply core 11 is attached so that a part of the magnetic flux of the outer core 1b flows.

図１および図２において、電源用鉄心１１に静止誘導機器の磁束の一部が流れることにより、電源用巻線１２に電圧が発生する。 In FIGS. 1 and 2, a voltage is generated in the power supply winding 12 due to a part of the magnetic flux of the stationary induction device flowing through the power supply iron core 11.

以下、本発明の実施例を、図面を用いて説明する。なお、実施例を説明するための各図において、同一の構成要素には同一の名称、符号を付して、その繰り返しの説明を省略する。 Hereinafter, examples of the present invention will be described with reference to the drawings. In addition, in each figure for demonstrating an embodiment, the same constituent elements are given the same name and reference numeral, and the repeated description thereof will be omitted.

本発明の実施例１の変圧器を、図３から図６を用いて説明する。実施例１は、単相変圧器に係るものである。 The transformer of the first embodiment of the present invention will be described with reference to FIGS. 3 to 6. The first embodiment relates to a single-phase transformer.

図３に実施例１の電源生成手段１０を示す。電源生成手段１０は、磁束を通すための電源用鉄心１１に三次巻線となる電源用巻線１２を巻いたものである。電源用鉄心１１は、例えば電磁鋼板やアモルファス磁性合金から成る薄板状磁性材料を積層して構成される。電源用鉄心１１は、変圧器の主鉄心１に流れている磁束を流す必要があるため、透磁率は主鉄心１の透磁率と同等以上の磁性材料であることが好ましい。また、電源用鉄心１１に電源用巻線１２を巻く際は、電源用鉄心１１と電源用巻線１２との間に絶縁紙１３を入れる。これは、電源用鉄心１１の端面部で電源用巻線１２が傷付き短絡することを防止するためのものである。 FIG. 3 shows the power source generating means 10 of the first embodiment. The power supply generating means 10 is formed by winding a power supply winding 12 as a tertiary winding around a power supply iron core 11 for passing magnetic flux. The power supply core 11 is formed by laminating a thin plate-shaped magnetic material made of, for example, an electromagnetic steel plate or an amorphous magnetic alloy. Since it is necessary for the power supply core 11 to flow the magnetic flux flowing through the main core 1 of the transformer, it is preferable that the magnetic permeability is a magnetic material equal to or higher than the magnetic permeability of the main core 1. When winding the power supply winding 12 around the power supply core 11, the insulating paper 13 is inserted between the power supply core 11 and the power supply winding 12. This is to prevent the power supply winding 12 from being damaged and short-circuited at the end face portion of the power supply iron core 11.

図４、５、６に、巻鉄心構造の静止誘導機器への電源生成手段の設置方法の一例を示す。図４は電源生成手段１０取り付け前の状態を、図５は電源生成手段１０取り付け後の状態を示す。また、図６は電源生成手段１０の固定後の状態を示す。 FIGS. 4, 5 and 6 show an example of a method of installing a power generation means in a stationary induction device having a wound iron core structure. FIG. 4 shows a state before the power generation means 10 is attached, and FIG. 5 shows a state after the power generation means 10 is attached. Further, FIG. 6 shows a state after the power generation means 10 is fixed.

巻鉄心の主鉄心１を固定用バンドで固定する方法と同要領で、電源生成手段の電源用鉄心１１に固定用バンド２１を巻き付けて主鉄心１に固定する。この時、電源用巻線１２を傷付けないように固定用バンド２１と電源用巻線１２間に絶縁物を入れる。電源用鉄心１１と主鉄心１との間が絶縁されていない場合は、絶縁物により絶縁することで、局所加熱を押さえることができる。また、磁束を安定して電源用鉄心１１に流すため電源用鉄心１１の面と主鉄心１の面の重なりを大きくする。また、固定用バンド２１での固定をより確実にするために主鉄心１のＲ部（肩部）まで重なる方が好ましい。 The fixing band 21 is wound around the power supply core 11 of the power generation means and fixed to the main core 1 in the same manner as the method of fixing the main core 1 of the wound core with the fixing band. At this time, an insulator is inserted between the fixing band 21 and the power supply winding 12 so as not to damage the power supply winding 12. When the power supply core 11 and the main core 1 are not insulated, local heating can be suppressed by insulating with an insulator. Further, in order to allow the magnetic flux to flow stably to the power supply core 11, the overlap between the surface of the power supply core 11 and the surface of the main core 1 is increased. Further, it is preferable that the main iron core 1 overlaps with the R portion (shoulder portion) in order to more reliably fix the fixing band 21.

図６に示すように、固定用バンド２１での固定後は中身固定金具２２で上下を覆い、電源用巻線１２の電線は主鉄心のＲ部と中身固定金具２２との間を通す。この時、中身固定金具２２の内側には電源用巻線１２の短絡防止ため、絶縁物を挟むことが好ましい。 As shown in FIG. 6, after fixing with the fixing band 21, the upper and lower parts are covered with the content fixing bracket 22, and the electric wire of the power winding 12 is passed between the R portion of the main iron core and the content fixing bracket 22. At this time, it is preferable to sandwich an insulator inside the content fixing metal fitting 22 in order to prevent a short circuit of the power supply winding 12.

本実施例によれば、変圧器の鉄心−コイル中身構造を変更することなく、また、鉄心−コイル中身構造の幅、奥行き寸法が増大することなく、また、一次、二次巻線の結線作業を変更することなく、電源生成手段を変圧器に取り付けることが可能となる。また、既存の変圧器に後付けによって、電源生成手段を取り付けることも可能である。そして、変圧器の付属装置などの他の装置を動作させるための電源を、静止誘導機器自体から低コストで安全に供給することができる。 According to this embodiment, the iron core-coil contents structure of the transformer is not changed, the width and depth dimensions of the iron core-coil contents structure are not increased, and the connection work of the primary and secondary windings is performed. It is possible to attach the power generation means to the transformer without changing. It is also possible to retrofit an existing transformer with a power generation means. Then, the power supply for operating other devices such as the accessory device of the transformer can be safely supplied from the static induction device itself at low cost.

更に、電源用鉄心を取り付けることにより、変圧器のヨーク部の鉄心断面積が増大するため、鉄損の増大を抑制、若しくは、鉄損を低減することができる。 Further, by attaching the iron core for power supply, the cross-sectional area of the iron core of the yoke portion of the transformer is increased, so that the increase in iron loss can be suppressed or the iron loss can be reduced.

図７に、本発明の実施例２の静止誘導機器を示す。図７は、電源生成手段１０の取り付け途中を示す図である。実施例２は、実施例１において電源用鉄心１１の長さを延長し、電源用鉄心１１を変圧器鉄心１の最外周にほぼ全周に巻き付けるものである。これにより、電源用鉄心１１が実施例１と比べてより安定して固定され、且つ、磁束が電源用鉄心１１により確実に入り、且つ、鉄損低減効果が大きくなる。 FIG. 7 shows a stationary induction device according to a second embodiment of the present invention. FIG. 7 is a diagram showing the installation of the power generation means 10. In the second embodiment, the length of the power supply core 11 is extended in the first embodiment, and the power supply core 11 is wound around the outermost circumference of the transformer core 1 almost all around. As a result, the power supply iron core 11 is more stably fixed as compared with the first embodiment, the magnetic flux is surely entered by the power supply iron core 11, and the iron loss reduction effect is increased.

図８に、本発明の実施例３の静止誘導機器を示す。実施例３は、三相三脚型変圧器に電源生成手段を取り付けたものである。 FIG. 8 shows a stationary induction device according to a third embodiment of the present invention. In the third embodiment, a power generation means is attached to a three-phase tripod type transformer.

It is composed of three main windings 2a that have been turned. The power generation means 10 including the power core 11 and the power winding 12 is attached over the upper and lower R portions (shoulders) of the outer core 1b. A part of the magnetic flux flowing through the outer core 1b flows through the power supply core 11, so that a voltage is generated in the power supply winding 12.

本実施例によればは、三相三脚型静止誘導機器の鉄心−コイル中身構造を変更することなく、また、鉄心−コイル中身構造の高さ、奥行き寸法が増大することなく、また、一次、二次巻線の結線作業を変更することなく、電源生成手段を取り付けることが可能となる。また、既存の変圧器に後付けによって、電源生成手段を取り付けることも可能である。そして、変圧器の付属装置などの他の装置を動作させるための電源を、静止誘導機器自体から低コストで安全に供給することができる。 According to this embodiment, the iron core-coil content structure of the three-phase tripod type stationary induction device is not changed, and the height and depth dimensions of the iron core-coil content structure are not increased, and the primary, It is possible to install the power generation means without changing the connection work of the secondary winding.

更に、電源用鉄心を取り付けることにより、脚部の鉄心断面積が増大するため、鉄損の増大を抑制、若しくは、鉄損を低減することができる。 Further, by attaching the iron core for power supply, the cross-sectional area of the iron core of the leg portion is increased, so that the increase in iron loss can be suppressed or the iron loss can be reduced.

A part of the magnetic flux flowing through the outer core 1b flows through the power supply core 11, so that a voltage is generated in the power supply winding 12.

本実施例によれば、三相三脚型静止誘導機器の鉄心−コイル中身構造を変更することなく、また、鉄心−コイル中身構造の高さ、幅、奥行き寸法が増大することなく、電源生成手段を取り付けることが可能となる。そして、変圧器の付属装置などの他の装置を動作させるための電源を、静止誘導機器自体から低コストで安全に供給することができる。 According to this embodiment, the power generation means without changing the iron core-coil content structure of the three-phase tripod type stationary induction device and without increasing the height, width, and depth dimension of the iron core-coil content structure. Can be installed. Then, the power supply for operating other devices such as the accessory device of the transformer can be safely supplied from the stationary induction device itself at low cost.

また、三相巻線２ａの上部に電源生成手段１０を配置することにより、実施例３に比べて、静止誘導機器の外形寸法が大きくなることが少ない。なお、電源生成手段１０は三相巻線２ａの下部に配置しても良い。 Further, by arranging the power generation means 10 on the upper part of the three-phase winding 2a, the external dimensions of the stationary induction device are less likely to be larger than those in the third embodiment. The power generation means 10 may be arranged below the three-phase winding 2a.
