Description
本発明は、鉄道用レールブレーキ兼用非接触給電装置に関するものである。 The present invention relates to a railway rail brake combined use non-contact power feeding device.
通常、非接触給電装置では、一次コイル（地上）と二次コイル（車上）の結合をよくするため、高周波でエネルギーを伝達する必要があり、大きな容量（ＶＡ) の電源装置が必要となる。
そこで、駆動用リニアモーターを非接触給電に併用する提案がなされている（下記特許文献１参照）。
Normally, in a non-contact power supply device, in order to improve the coupling of the primary coil (ground) and the secondary coil (on the vehicle), it is necessary to transmit energy at a high frequency, and a power supply device with a large capacity (VA) is required. .
In view of this, a proposal has been made to use a driving linear motor for non-contact power feeding (see Patent Document 1 below).
一方、本発明者らは、小容量の電源のみで、レール発熱の温度上昇が低減できる交流励磁レールブレーキ装置を提案した（下記特許文献２及び非特許文献１参照）。 On the other hand, the present inventors have proposed an AC excitation rail brake device that can reduce the temperature rise of rail heat generation with only a small-capacity power source (see Patent Document 2 and Non-Patent Document 1 below).
しかしながら、従来、レールブレーキ電機子を非接触給電の二次コイルとして兼用する着想はなく、レールブレーキ電機子を非接触給電の二次コイルとして兼用することにより、ブレーキの機能を有するとともに、非接触給電のために別個に二次コイルを設置しなくても給電することができるようにしたものは存在していない。
本発明は、上記した状況に鑑みて、車上の二次コイルとしてのレールブレーキ電機子と鉄道用レールに埋め込まれた一次コイルとにより、漏れ磁束の少ない磁気回路を構成することができ、商用周波数程度の低い周波数でエネルギーを良好に伝達するとともに鉄道車両の重量増を抑制することができる、レールブレーキ兼用非接触給電装置を提供することを目的とする。
However, conventionally, there is no idea to use the rail brake armature as a secondary coil for non-contact power feeding. By using the rail brake armature as a secondary coil for non-contact power feeding, it has a brake function and non-contact power. There is no device that can supply power without separately providing a secondary coil for supplying power.
In view of the above situation, the present invention can configure a magnetic circuit with less leakage magnetic flux by using a rail brake armature as a secondary coil on a vehicle and a primary coil embedded in a rail for a railway. An object of the present invention is to provide a non-contact power supply device that also serves as a rail brake, which can transmit energy satisfactorily at a frequency as low as about a frequency and can suppress an increase in weight of a railway vehicle.
本発明は、上記目的を達成するために、

以下、本発明の実施の形態について詳細に説明する。
図１は本発明の実施例を示す鉄道用レールブレーキ兼用非接触給電装置（車両停止時、給電地点）の模式図、図２はその鉄道用レールブレーキ兼用非接触給電装置（車両走行時）の模式図である。
これらの図において、１は鉄道用レール、２は給電地点の鉄道用レールに埋め込まれた非接触給電一次コイル、３はこの非接触給電一次コイル２の表面に配置される非磁性材からなる絶縁カバー、４は鉄道車両の台車、５は鉄道車両の台車４の下方に配置され、非接触給電一次コイル２と対向する非接触給電二次コイル、６は非接触給電一次コイル２と対向する非接触給電二次コイル５との間のギャップ、７は非接触給電一次コイル２に電力を供給する電源、８は非接触給電二次コイル５に接続される電力変換器（蓄電池やコンデンサなど）である。
Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a schematic diagram of a railway rail brake combined use non-contact power supply apparatus (when the vehicle is stopped, a power supply point) showing an embodiment of the present invention, and FIG. 2 shows the railroad rail brake combined use noncontact power supply apparatus (when the vehicle is running). It is a schematic diagram.
In these drawings, 1 is a rail for rails, 2 is a non-contact power supply primary coil embedded in a rail for rails at a power supply point, and 3 is an insulation made of a non-magnetic material disposed on the surface of the non-contact power supply primary coil 2. Cover 4 is a bogie of the railway vehicle, 5 is disposed below the bogie 4 of the railway car, and is a non-contact power feeding secondary coil that faces the non-contact feeding primary coil 2, and 6 is a non-contact that faces the non-contact feeding primary coil 2. A gap between the contact power supply
そこで、図１に示すように、給電地点に停車時は、電源７から非接触給電一次コイル２を励磁し、ギャップ６を介して、非接触給電二次コイル５に非接触で電気エネルギーを伝達する。非接触給電一次コイル２、非接触給電二次コイル５とも強磁性体による磁気回路を構成するため、電源７からの電流は、商用周波数領域でも充分な誘起電圧を得ることができる。
Therefore, as shown in FIG. 1, when stopping at the power feeding point, the non-contact power feeding primary coil 2 is excited from the
鉄道車両の走行時（走行区間）では、図２に示すように、鉄道用レール１と非接触給電二次コイルとしての交流励磁レールブレーキ装置の電機子５′は対向し、非接触給電二次コイル５′（交流励磁レールブレーキ装置の電機子５′）は、交流励磁レールブレーキの電機子としてブレーキ動作を行う。
ここで、片台車に搭載する交流励磁レールブレーキを想定し、給電できるエネルギーを、例えば短時間定格で見積もると下記のようになる。
When the railway vehicle is traveling (traveling section), as shown in FIG. 2, the
Here, assuming an AC excitation rail brake mounted on a single carriage, the energy that can be supplied is estimated by, for example, short-time rating as follows.
一次入力は２３０ｋＷ（３８０ｋＶＡ）、一次銅損は３０ｋＷ、同期ワットは２００ｋＷ、二次銅損は３０ｋＷ、二次出力は１７０ｋＷ（３２０ｋＶＡ）となり、すなわち、各台車に２本、一両４本のレールブレーキでは、１７０ｋＷ×４本＝６８０ｋＷとなり、蓄電池ハイブリッド型の通勤電車の駆動も可能な電力が得られる見込みとなる。
なお、この実施例では、停車時のみ非接触給電を行うことを想定しているが、非接触給電一次コイルを延伸することにより、停車時以外の走行時のような車両と地上に相対運動があるような場合でも給電することができる。
The primary input is 230 kW (380 kVA), the primary copper loss is 30 kW, the synchronous watt is 200 kW, the secondary copper loss is 30 kW, the secondary output is 170 kW (320 kVA). For the brake, 170 kW × 4 pieces = 680 kW, and it is expected that electric power capable of driving a storage battery hybrid type commuter train will be obtained.
In this embodiment, it is assumed that non-contact power supply is performed only when the vehicle is stopped.However, by extending the non-contact power supply primary coil, relative movement between the vehicle and the ground during traveling other than when the vehicle is stopped can be achieved. Even in some cases, power can be supplied.
また、本発明は上記実施例に限定されるものではなく、本発明の趣旨に基づき種々の変形が可能であり、これらを本発明の範囲から排除するものではない。 The present invention is not limited to the above-described embodiments, and various modifications can be made based on the spirit of the present invention, and these are not excluded from the scope of the present invention.
本発明の鉄道用レールブレーキ兼用非接触給電装置は、漏れ磁束の少ない磁気回路を構成することができ、低い周波数でエネルギーを良好に伝達するとともに鉄道車両の重量増を抑制することができる、レールブレーキ兼用非接触給電装置として利用可能である。 The railway rail brake combined contactless power supply device of the present invention can constitute a magnetic circuit with a small amount of leakage magnetic flux, can transmit energy at a low frequency satisfactorily, and can suppress an increase in weight of a railway vehicle. It can be used as a non-contact power feeding device that also serves as a brake.
