Description
本発明は、車両用リアクトルに関し、特に、軸線回りに巻回されるコイルを有するリアクトル本体を有し、軸線が鉄道車両の床面または天井面に直交する姿勢で鉄道車両の床下または天井裏に固定されるものに関する。 The present invention relates to a vehicle reactor, and in particular, has a reactor body having a coil wound around an axis, and the axis is perpendicular to the floor surface or ceiling surface of the railway vehicle and is below the floor or behind the ceiling of the railway vehicle. Concerning what is fixed.
電動式鉄道車両には、半導体素子を利用した制御装置から発生する高調波等の電気的ノイズを架線に流さないために、インバーターへの直流入力回路に電気的に接続され、コンデンサと共に平滑回路を構成する車両用リアクトルが設けられている。この種の車両用リアクトルは、一般に、軸線回りに巻回されるコイルを有するリアクトル本体を有し、鉄道車両の床下や天井裏に支持部材により固定される。 The electric railway vehicle is electrically connected to the DC input circuit to the inverter so that electrical noise such as harmonics generated from the control device using the semiconductor element does not flow through the overhead line, and a smoothing circuit is installed together with the capacitor. The reactor for vehicles which comprises is provided. This type of vehicle reactor generally has a reactor body having a coil wound around an axis, and is fixed to a lower floor or a ceiling of a railway vehicle by a support member.
ここで、力行または回生制動時に車両用リアクトルに電流が流れると、磁束が発生する。そして、このリアクトルで発生した磁束が車両内へと漏洩すると、磁気カードや電子機器等の乗客の所持品に悪影響を及ぼす虞がある。そこで、鉄道車両内への磁束の漏洩量を可及的に低減するため、車両の床または天井とリアクトル本体との間に磁気遮蔽板を設けることが提案されている（例えば、特許文献１参照）。 Here, when a current flows through the vehicle reactor during power running or regenerative braking, magnetic flux is generated. And if the magnetic flux which generate | occur | produced in this reactor leaks in a vehicle, there exists a possibility of having a bad influence on passenger's possessions, such as a magnetic card and an electronic device. Therefore, in order to reduce the amount of magnetic flux leakage into the railway vehicle as much as possible, it has been proposed to provide a magnetic shielding plate between the floor or ceiling of the vehicle and the reactor body (see, for example, Patent Document 1). ).
ところで、車両用リアクトルを鉄道車両の床下や天井裏に設置する場合、上記特許文献１記載のように、軸線が鉄道車両の床面または天井面に平行な姿勢にして固定されるもの（所謂横置式）の他、軸線が鉄道車両の床面または天井面に直交する姿勢で車両用リアクトルが固定されるもの（所謂縦置式）がある。そして、所謂縦置式の場合には、磁気遮蔽板を設けても、その板厚に関係なく、鉄道車両内への磁束の漏洩量を効果的に低減できないことが判明した。 By the way, when the vehicle reactor is installed under the floor or the ceiling of the railway vehicle, as described in Patent Document 1, the axis is fixed in a posture parallel to the floor or ceiling surface of the railway vehicle (so-called horizontal There is another type in which the vehicle reactor is fixed in a posture in which the axis is orthogonal to the floor surface or ceiling surface of the railway vehicle (so-called vertical type). In the case of the so-called vertical type, it has been found that even if a magnetic shielding plate is provided, the amount of leakage of magnetic flux into the railway vehicle cannot be effectively reduced regardless of the plate thickness.
本発明は、以上の点に鑑み、車両用リアクトルが縦置式で鉄道車両の床下や天井裏に設置される場合に、鉄道車両内への磁束の漏洩を効果的に低減することができる車両用リアクトルを提供することをその課題とするものである。 In view of the above points, the present invention provides a vehicular reactor that can effectively reduce leakage of magnetic flux into a railway vehicle when the vehicle reactor is vertically installed and installed under the floor or behind the ceiling of the railway vehicle. The challenge is to provide a reactor.
上記の課題を解決するために、軸線回りに巻回されるコイルを有するリアクトル本体を有し、軸線が鉄道車両の床面または天井面に直交する姿勢で鉄道車両の床下または天井裏に固定される本発明の車両用リアクトルは、コイルを軸線回りに囲う第１磁気遮蔽板と、第１磁気遮蔽板の鉄道車両の床または天井側の互いに向かい合う端面に、軸線に向けて傾斜して夫々延びるフラップ部とを備えて軸線方向上側の面が開口した保護カバーを有し、床または天井とフラップ部との間に軸線方向に間隔を存して配置される少なくとも２枚の第２磁気遮蔽板を備え、各第２磁気遮蔽板の面積は保護カバーの開口面積よりも大きく、且つ軸線方向上側に位置する第２磁気遮蔽板の面積は軸線方向下側に位置する第２遮蔽板の面積よりも大きいことを特徴とする。 In order to solve the above problems, a reactor main body having a coil wound around an axis is provided, and the axis is fixed to the floor or the ceiling of the railroad vehicle in a posture perpendicular to the floor or ceiling surface of the railcar. The vehicle reactor according to the present invention includes a first magnetic shielding plate that surrounds the coil around the axis, and an end surface facing each other on the floor or ceiling side of the railcar of the first magnetic shielding plate that extends toward the axis. a protective cover which axially upper surface is opened and a flap portion, the second magnetic shielding plates of at least two arranged at intervals in the axial direction between the floor or ceiling and the flap portion The area of each second magnetic shielding plate is larger than the opening area of the protective cover, and the area of the second magnetic shielding plate located on the upper side in the axial direction is larger than the area of the second shielding plate located on the lower side in the axial direction characterized in that it is also large To.
本発明によれば、第１磁気遮蔽板を備えるため、車両用リアクトルに電流が流れることで磁束が発生したとき、第１磁気遮蔽板中を通って閉じる磁束の量が増加すると共に、軸線側の磁束が第１磁気遮蔽板側へと引き寄せられ、鉄道車両の床面または天井面に向かう磁束の漏洩量が低減され、それに加えて、フラップ部を備えるため、上記床面または天井面に向かう磁束が当該床面または天井面に対して横方向に拡散され、床面または天井面に向かう磁束が更に低減される。従って、車両用リアクトルが縦置式で鉄道車両の床下や天井裏に設置される場合に、鉄道車両内への磁束の漏洩を効果的に低減することができる。 According to the present invention, since the first magnetic shielding plate is provided, when the magnetic flux is generated by the current flowing through the vehicle reactor, the amount of the magnetic flux closing through the first magnetic shielding plate is increased, and the axial side Magnetic flux is attracted toward the first magnetic shielding plate, the amount of leakage of the magnetic flux toward the floor surface or ceiling surface of the railway vehicle is reduced, and in addition to this, since the flap portion is provided, the magnetic flux is directed toward the floor surface or ceiling surface. The magnetic flux is diffused in the transverse direction with respect to the floor surface or ceiling surface, and the magnetic flux toward the floor surface or ceiling surface is further reduced. Therefore, when the vehicle reactor is installed vertically and installed under the floor or behind the ceiling of the railway vehicle, leakage of magnetic flux into the railway vehicle can be effectively reduced.
また、本発明によれば、前記床または天井とフラップ部との間に軸線方向に間隔を存して配置される少なくとも２枚の第２磁気遮蔽板を備え、各第２磁気遮蔽板の面積は保護カバーの開口面積よりも大きく、且つ軸線方向上側に位置する第２磁気遮蔽板の面積は軸線方向下側に位置する第２遮蔽板の面積よりも大きいため、床面または天井面に向かう磁束をより一層低減することができる。 Further, according to the present invention, Bei example at least two second magnetic shielding plates are arranged at intervals in the axial direction between the floor or ceiling and the flap portion, of the second magnetic shielding plate Since the area is larger than the opening area of the protective cover and the area of the second magnetic shielding plate located on the upper side in the axial direction is larger than the area of the second shielding plate located on the lower side in the axial direction , The magnetic flux which goes can be reduced further.
以下、図面を参照して、インバーターへの直流入力回路に電気的に接続され、コンデンサと共に平滑回路を構成する車両用リアクトルを鉄道車両の床下に取り付ける場合を例にその実施形態を説明する。 Hereinafter, an embodiment will be described with reference to the drawings, taking as an example a case where a vehicle reactor that is electrically connected to a DC input circuit to an inverter and constitutes a smoothing circuit together with a capacitor is attached under the floor of a railway vehicle.
図１及び図２を参照して、１は、車両用リアクトルのリアクトル本体である。リアクトル本体１は、軸線２１回りに巻回されるコイル２と、このコイル２を包含して支持する保護カバー３とを備え、保護カバー３に連結される支持金具４を介して鉄道車両の床Ｆに吊設されている。なお、保護カバー３の鉄道車両への固定方法はこれに限定されるものではない。そして、コイル２が、その軸線２１が鉄道車両の床Ｆに直交する姿勢、即ち、鉛直方向に軸線２１がのびるように保護カバー３内に保持されている。 1 and 2, reference numeral 1 denotes a reactor main body of a vehicle reactor. The reactor main body 1 includes a coil 2 wound around an axis 21 and a protective cover 3 that supports the coil 2 by including the coil 2. It is suspended from F. Note that the method of fixing the protective cover 3 to the railway vehicle is not limited to this. And the coil 2 is hold | maintained in the protective cover 3 so that the axis line 21 may extend in the attitude | position in which the axis line 21 orthogonally crosses the floor F of a rail vehicle, ie, a perpendicular direction.
保護カバー３は、上面が開口した箱状のものであり、磁性材料で形成されている。磁性材料としては、鉄よりも高透磁率で飽和磁束密度の高いものが望ましく、例えば、ＳＳ４００、ＳＰＨＣまたはＳＰＣＣを用いることができる。そして、本実施形態では、保護カバー３の各側壁部３１がコイル２を軸線２１回りに囲う第１磁気遮蔽板として役割を果たす。また、互いに向かい合う各側壁部３１の上端には、その上辺全長に亘って、軸線２１に向けて傾斜して夫々延びるようにフラップ部３２が形成されている。両フラップ部３２の水平面に対する角度や長さは、鉄道車両内への磁束の漏洩量に応じて適宜設定することができる。 The protective cover 3 has a box shape with an upper surface opened, and is made of a magnetic material. As the magnetic material, a material having a higher magnetic permeability and a higher saturation magnetic flux density than iron is desirable. For example, SS400, SPHC, or SPCC can be used. In the present embodiment, each side wall 31 of the protective cover 3 serves as a first magnetic shielding plate that surrounds the coil 2 around the axis 21. Moreover, the flap part 32 is formed in the upper end of each side wall part 31 which faces each other so that it may incline and extend toward the axis line 21 over the full length of the upper side. The angle and length of the flap portions 32 with respect to the horizontal plane can be appropriately set according to the amount of magnetic flux leaked into the railway vehicle.
床Ｆとフラップ部３２との間には、第２磁気遮蔽板としての２枚の遮蔽板５ａ，５ｂが上下方向に間隔を存して設けられている。各遮蔽板５ａ，５ｂは、保護カバー３上面の開口面積より大きな面積を有する平面視矩形で磁性材料製の板材で夫々構成され、その主面５１が上下方向に直交する姿勢で支持金具４により支持されている。この場合、各遮蔽板５ａ，５ｂの面積は、鉄道車両内への磁束の漏洩量に応じて適宜設定することができる。本実施形態では、床Ｆに向かう磁束をより一層低減するために、鉛直方向上側に位置する遮蔽板５ｂの面積を下側の遮蔽板５ａより大きくしている（例えば、遮蔽板５ｂが遮蔽板５ａの１．２倍の面積を有する）。また、互いに向かい合うフラップ部３２側の遮蔽板５ａ，５ｂの端面を下方に折り曲げて機械的強度を増加させるように構成することが好ましく、磁性材料としては、上記第１磁気遮蔽板と同一のものが用いられる。フラップ部３２の上端と鉛直方向下側の遮蔽板５ａの主面５１との間の間隔Ｄ１と、各遮蔽板５ａ，５ｂの主面５１間の間隔Ｄ２とは、鉄道車両内への磁束の漏洩量に応じて適宜設定される（例えば、７０ｍｍ）。 Between the floor F and the flap part 32, two shielding plates 5a and 5b as second magnetic shielding plates are provided with a gap in the vertical direction. Each of the shielding plates 5a and 5b is made of a plate material made of a magnetic material having a rectangular shape in plan view having an area larger than the opening area of the upper surface of the protective cover 3, and the main surface 51 is perpendicular to the vertical direction by the support bracket 4 in a posture. It is supported. In this case, the area of each shielding plate 5a, 5b can be appropriately set according to the amount of magnetic flux leakage into the railway vehicle. In the present embodiment, in order to further reduce the magnetic flux toward the floor F, the area of the shielding plate 5b located on the upper side in the vertical direction is made larger than that of the lower shielding plate 5a (for example, the shielding plate 5b is a shielding plate). 5a is 1.2 times the area). Further, it is preferable that the end faces of the shielding plates 5a and 5b on the side of the flap portion 32 facing each other are bent downward to increase the mechanical strength, and the magnetic material is the same as that of the first magnetic shielding plate. Is used. The distance D1 between the upper end of the flap portion 32 and the main surface 51 of the shielding plate 5a on the lower side in the vertical direction and the distance D2 between the main surfaces 51 of the shielding plates 5a and 5b are the magnetic flux into the railway vehicle. It is set appropriately according to the amount of leakage (for example, 70 mm).
以上の実施形態によれば、磁性材料の保護カバー３でコイル２の周囲を囲うようにしたため、車両用リアクトルに電流が流れることで磁束が発生したとき、保護カバー３の各側壁部３１を通って閉じる磁束の量が増加すると共に、軸線２１側の磁束が各側壁部３１へと引き寄せられ、床Ｆに向かう磁束の漏洩量が低減され、それに加えて、フラップ部３２を備えるため、床Ｆに向かう磁束が当該床Ｆの下面に対して横方向に拡散され、床Ｆに向かう磁束が更に低減される。従って、車両用リアクトルが縦置式で鉄道車両の床下に設置した場合でも、鉄道車両内への磁束の漏洩を効果的に低減することができる。更に、所定間隔を存して少なくとも２枚の遮蔽板５ａ，５ｂを設けることで、床Ｆに向かう磁束をより一層低減することができる。 According to the above embodiment, since the coil 2 is surrounded by the protective cover 3 made of a magnetic material, when a magnetic flux is generated by a current flowing through the vehicle reactor, the protective cover 3 passes through each side wall 31 of the protective cover 3. As the amount of magnetic flux to be closed increases, the magnetic flux on the axis 21 side is attracted to each side wall portion 31, and the leakage amount of magnetic flux toward the floor F is reduced. In addition to this, since the flap portion 32 is provided, the floor F The magnetic flux toward the floor F is diffused laterally with respect to the lower surface of the floor F, and the magnetic flux toward the floor F is further reduced. Accordingly, even when the vehicle reactor is installed vertically and installed under the floor of the railway vehicle, leakage of magnetic flux into the railway vehicle can be effectively reduced. Furthermore, the magnetic flux toward the floor F can be further reduced by providing at least two shielding plates 5a and 5b with a predetermined interval.
以上の効果を確認するために、図１，２に示す車両用リアクトルを用いて次の実験（シュミレーション）を行った。本実験では、コイル２の上面と床Ｆの下面との間の間隔を５００ｍｍ、コイル２の通電電流を８００Ａ、保護カバー３及び磁気遮蔽板５ａ、５ｂをＳＳ４００製のものとし、そのときの磁束密度を図３（ａ）〜（ｄ）に示すコンター図及びベクトル図として得た。 In order to confirm the above effects, the following experiment (simulation) was performed using the vehicle reactor shown in FIGS. In this experiment, the distance between the upper surface of the coil 2 and the lower surface of the floor F is 500 mm, the energizing current of the coil 2 is 800A, the protective cover 3 and the magnetic shielding plates 5a and 5b are made of SS400, and the magnetic flux at that time The density was obtained as a contour diagram and a vector diagram shown in FIGS.
この場合、試料１は、コイル２を第１磁気遮蔽板としての上面を開口した磁性材料製の保護カバー３内に格納せず、床面Ｆから２７０ｍｍの位置に１枚の第２磁気遮蔽板のみを配置したものとした（従来例に相当）。試料２は、試料１に加えて、コイル２を第１磁気遮蔽板としての上面を開口した磁性材料製の保護カバー３（但し、フラップ部を設けていない）内に格納したものとした、試料３は、試料２に加えて、フラップ部３２を一体に形成したものとした。試料４は、試料３に加えて、床面から１９０ｍｍの位置に他の第２磁気遮蔽板を配置したものとした（上記実施形態のものに相当）。 In this case, the sample 1 does not store the coil 2 in the protective cover 3 made of a magnetic material having an upper surface opened as a first magnetic shielding plate, and is one second magnetic shielding plate at a position of 270 mm from the floor surface F. It was assumed that only this was arranged (corresponding to the conventional example). Sample 2 is a sample in which, in addition to sample 1, coil 2 was stored in protective cover 3 made of a magnetic material having an upper surface opened as a first magnetic shielding plate (however, no flap portion was provided). 3, in addition to the sample 2, the flap portion 32 was integrally formed. In sample 4, in addition to sample 3, another second magnetic shielding plate was disposed at a position 190 mm from the floor (corresponding to the above embodiment).
以上によれば、試料１では、１枚の磁気遮蔽板を設けても、磁束の漏洩量が多いことが判る（図３（ａ）参照）。試料２では、コイル２の周囲を第１磁気遮蔽板としての保護カバー３で囲うことで、側壁部３１中を通って閉じる磁束の量が増加すると共に、軸線側の磁束が側壁部３１側へと引き寄せられ、床Ｆに向かう磁束の漏洩量が低減されることが判る（図３（ｂ）参照）。そして、試料３では、フラップ部３２が存することで、床Ｆに向かう磁束が当該床Ｆの下面に対して横方向に拡散され、床Ｆに向かう磁束が更に低減され（図３（ｃ）参照）、試料４では、二枚の磁気遮蔽板５ａ，５ｂを設けることで、効果的に床Ｆを貫通するものが低減されることが判る。 According to the above, it can be seen that the sample 1 has a large amount of leakage of magnetic flux even if a single magnetic shielding plate is provided (see FIG. 3A). In the sample 2, by enclosing the periphery of the coil 2 with the protective cover 3 as the first magnetic shielding plate, the amount of magnetic flux closing through the side wall portion 31 is increased, and the magnetic flux on the axial line side is moved to the side wall portion 31 side. The amount of magnetic flux leakage toward the floor F is reduced (see FIG. 3B). And in the sample 3, since the flap part 32 exists, the magnetic flux which goes to the floor F is spread | diffused transversely with respect to the lower surface of the said floor F, and the magnetic flux which goes to the floor F is further reduced (refer FIG.3 (c)). ) In the sample 4, it can be seen that by providing the two magnetic shielding plates 5a and 5b, the number of effectively penetrating the floor F is reduced.
以上、本発明の実施形態について説明したが、本発明はこれに限定されるものではない。本実施形態では、保護カバー３が第１磁気遮蔽板を兼用するものを例に説明したが、コイルを格納するものと別体で設けることもできる。また、第２磁気遮蔽板を２枚としたものを例に説明したが、３枚以上設置することも可能である。 As mentioned above, although embodiment of this invention was described, this invention is not limited to this. In the present embodiment, the protective cover 3 also serves as the first magnetic shielding plate. However, the protective cover 3 may be provided separately from the one that stores the coil. Moreover, although the description has been given by taking an example in which two second magnetic shielding plates are provided, it is possible to install three or more.
