Description

本発明は、鉄道設備用の複数の電気・電子機器を、高強度材料と高導電性材料とを組み合わせたシェルタ内に集約して収納するようにした鉄道用電気・電子機器の収納装置に関し、詳しくは、高強度材料として主に鉄を使用し、高導電性材料として主に銅を使用すると共に、シェルタに受電部を設けて落雷時の電流を速やかに大地に流すことができる収納装置に関するものである。   The present invention relates to a storage device for railway electrical / electronic devices that is configured to aggregate and store a plurality of electrical / electronic devices for railway facilities in a shelter combining a high-strength material and a highly conductive material, More specifically, the present invention relates to a storage device that mainly uses iron as a high-strength material and mainly uses copper as a high-conductivity material, and has a power receiving unit in the shelter to allow a current during a lightning strike to flow quickly to the ground. Is.

鉄道の駅構内または信号機や踏切の近辺、線路沿線などには、信号設備、踏切設備、転轍設備、ＡＴＣシステム等を制御する各種の制御装置、通信装置、電源装置、保安器、電力変換器等の鉄道用電気・電子機器が設置されており、これらの機器は信号用器具箱や踏切用器具箱に収納されている。
信号用器具箱や踏切用器具箱は、複数まとめて一カ所に設置されることは少なく、個々の器具箱が何年か隔てて所定位置に設置されるため、新旧の器具箱が点在している場合が多い。 Various control devices, communication devices, power supply devices, safety devices, power converters for controlling signal facilities, railroad crossing facilities, switch facilities, ATC systems, etc. in railway stations, in the vicinity of traffic lights and railroad crossings, along railway lines, etc. Such electrical and electronic equipment for railways are installed, and these equipment are housed in signal equipment boxes and railroad crossing equipment boxes.
Signal equipment boxes and railroad crossing equipment boxes are rarely installed in one place at a time, and individual equipment boxes are installed at predetermined positions several years apart, so old and new equipment boxes are scattered. There are many cases.

例えば、図２は、駅周辺の器具箱の設置状態を概念的に示した図である。
図２において１はプラットホーム、２は線路、３はき電線、４ａ，４ｂ，４ｃは器具箱、５は器具箱４ａ，４ｂ，４ｃ内の機器同士を接続するケーブルであり、器具箱４ａ，４ｂ，４ｃの筺体及びその内部機器は、それぞれ個別に接地されているものとする。 For example, FIG. 2 is a diagram conceptually showing the installation state of the instrument boxes around the station.
In FIG. 2, 1 is a platform, 2 is a track, 3 feeders, 4a, 4b and 4c are instrument boxes, 5 is a cable for connecting devices in the instrument boxes 4a, 4b and 4c, and the instrument boxes 4a and 4b. , 4c and its internal devices are individually grounded.

このような状態で、例えば器具箱４ａ近くのき電線３や線路２に落雷し、大地に雷サージ電流が流れると、落雷点の近傍にある器具箱４ａの筺体電位が上昇する。
これに対し、器具箱４ａから離れた場所にある器具箱４ｂ，４ｃ等の筺体電位は器具箱４ａから遠くなるほど低下するので、図示するように器具箱４ａ，４ｂ，４ｃの筺体間に電位差が発生する。ここで、器具箱４ａ，４ｂ，４ｃの内部機器がそれぞれ筺体に接地されているとすれば、器具箱４ａ，４ｂ，４ｃごとに内部機器の接地電位に差が生じることになり、これによって内部機器に過電圧が印加されて故障や破損を招くという問題がある。 In this state, for example, when lightning strikes the feeder 3 or the line 2 near the instrument box 4a and a lightning surge current flows to the ground, the housing potential of the instrument box 4a near the lightning point increases.
On the other hand, since the body potential of the instrument boxes 4b, 4c, etc. located away from the instrument box 4a decreases with increasing distance from the instrument box 4a, there is a potential difference between the chassis of the instrument boxes 4a, 4b, 4c as shown in the figure. Occur. Here, if the internal devices of the instrument boxes 4a, 4b, and 4c are grounded to the housing, respectively, a difference occurs in the ground potential of the internal device for each of the instrument boxes 4a, 4b, and 4c. There is a problem in that overvoltage is applied to the equipment, leading to failure or damage.

なお、本発明に関連する従来技術としては、例えば、特許文献１のように防水性を向上させた鉄道信号用器具箱や、特許文献２のように耐震性を向上させた鉄道信号用器具箱が知られている。   In addition, as a prior art relevant to this invention, the instrument box for railway signals which improved waterproofness like patent document 1, for example, and the instrument box for railway signals which improved earthquake resistance like patent document 2 It has been known.

特開２００５−５３４３６号公報JP 2005-53436 A 特開２００４−１７９３２号公報JP 2004-17932 A

この種の器具箱の従来技術としては、前述したように防水性や耐震性の向上を目的としたものが数多く提案されている。しかしながら、器具箱自体に雷保護装置を内蔵したり、複数の器具箱が点在する状況における落雷対策を考慮したものは存在せず、器具箱内の各種の機器を落雷から効果的に保護する対策が切望されていた。   As the prior art of this type of instrument box, many have been proposed for the purpose of improving waterproofness and earthquake resistance as described above. However, there is no device that incorporates lightning protection devices in the device box itself, or that considers lightning protection measures in situations where multiple device boxes are scattered, and effectively protects various devices in the device box from lightning strikes. Measures were anxious.

そこで、本発明の解決課題は、鉄道設備用の制御装置、通信装置、保安器、各種変換器等の複数の電気・電子機器をシェルタ内に集約して収納すると共に、前記シェルタの上部に受電部を形成し、かつシェルタの外部筺体を高強度材料と高導電性材料とを組み合わせて形成し、前記電気・電子機器を受電部及び高導電性材料と共に等電位接地することにより、落雷による機器の故障、破損を防止して信号設備や踏切設備等の信頼性を高めた鉄道用電気・電子機器の収納装置を提供することにある。   Therefore, the problem to be solved by the present invention is that a plurality of electric / electronic devices such as a control device for railway facilities, a communication device, a protector, and various converters are aggregated and stored in the shelter, and power is received at the upper portion of the shelter. And forming the outer casing of the shelter with a combination of a high-strength material and a highly conductive material, and grounding the electrical / electronic device together with the power receiving unit and the highly conductive material, thereby causing lightning strikes. It is an object of the present invention to provide a storage device for electrical / electronic equipment for railways, which prevents the breakdown and breakage of the railway and improves the reliability of signal equipment and railroad crossing equipment.

以下、図１を参照しつつ本発明の実施形態を説明する。
図１において、１０は、この実施形態に係る収納装置の本体を構成するシェルタであり、その外部筺体１０Ｄの上部には高導電性材料からなる受電部１５が配置され、任意箇所の外壁または内壁には、銅などからなる高導電性材料が配置されている。この高導電性材料は、板状材料、線状材料等、任意の形状を取り得るものであり、前記受電部１５と電気的に接続されている。なお、シェルタ１０の外部筺体１０Ｄには、高導電性材料のほかに、所定の強度を保つために鉄板等からなる高強度材料が使用されているが、これらについては後述する図３により説明する。 Hereinafter, an embodiment of the present invention will be described with reference to FIG.
In FIG. 1, reference numeral 10 denotes a shelter constituting the main body of the storage device according to this embodiment, and a power receiving portion 15 made of a highly conductive material is disposed on the outer casing 10 </ b> D, and an outer wall or inner wall at an arbitrary location. Is provided with a highly conductive material made of copper or the like. The highly conductive material can take an arbitrary shape such as a plate-like material or a linear material, and is electrically connected to the power receiving unit 15. The outer casing 10D of the shelter 10 uses a high-strength material made of an iron plate or the like in order to maintain a predetermined strength in addition to the high-conductivity material. These will be described with reference to FIG. 3 to be described later. .

シェルタ１０の内部空間１０Ａには、複数の内部筺体１１，１２，１３，１４，……が配置されている。シェルタ１０の下部には、外線２１を引き込んで収容するための外線収容部１０Ｂが設けられ、シェルタ１０の上部には、内線２２を収容するための内線収容部１０Ｃが設けられている。   In the internal space 10 </ b> A of the shelter 10, a plurality of internal housings 11, 12, 13, 14,. At the lower part of the shelter 10, an outer line accommodating part 10 </ b> B for drawing and accommodating the outer line 21 is provided, and at the upper part of the shelter 10, an inner line accommodating part 10 </ b> C for accommodating the inner line 22 is provided.

外線２１側の内部筺体１１には、保護・変換装置１１ａが収納されている。この保護・変換装置１１ａは、少なくともＳＰＤ等の雷保護用の保安器を備えている。また、保護・変換装置１１ａには、外線２１及び内線２２の信号形態（直流・交流）に従って電力変換を行うインバータやコンバータ、変圧器、あるいは、電気信号と光信号とを変換する電気／光変換器、光／電気変換器、無線通信装置等の各種の変換器が、必要に応じて含まれる。   A protection / conversion device 11a is accommodated in the inner casing 11 on the outer line 21 side. The protection / conversion device 11a includes at least a lightning protection protector such as SPD. Further, the protection / conversion device 11a includes an inverter, a converter, a transformer for converting power according to the signal form (direct current / alternating current) of the outer line 21 and the inner line 22, or an electric / optical conversion for converting an electric signal and an optical signal. Various converters such as a converter, an optical / electrical converter, and a wireless communication device are included as necessary.

また、他の内部筺体１２〜１４には、信号設備や踏切設備、転轍設備、ＡＴＣシステム等を制御し、あるいはこれらとの間で信号を授受するための制御装置、通信装置等の各種の電気・電子機器１２ａ〜１４ａが収納されている。保護・変換装置１１ａと電気・電子機器１２ａ、及び、電気・電子機器１２ａ〜１４ａの相互間は、内線２２によって接続されている。なお、保護・変換装置１１ａも鉄道用の電気・電子機器であることに変わりはなく、「保護・変換装置」という名称は便宜的なものに過ぎない。   In addition, the other internal casings 12 to 14 control various signal equipment, railroad crossing equipment, rolling equipment, ATC system, etc., or various devices such as control devices and communication devices for transmitting / receiving signals to / from these. The electric / electronic devices 12a to 14a are accommodated. The protection / conversion device 11a, the electric / electronic device 12a, and the electric / electronic devices 12a to 14a are connected by an extension line 22. The protection / conversion device 11a is also an electric / electronic device for railways, and the name “protection / conversion device” is merely for convenience.

保護・変換装置１１ａ及び電気・電子機器１２ａ〜１４ａは、共通接地線１９によりシェルタ１０の外部筺体１０Ｄに接続され、この外部筺体１０Ｄは一点にて接地されている。図示されていないが、電気・電子機器１２ａ〜１４ａ等の電源回路も内部筺体１２〜１４に収納されており、前記共通接地線１９により一括して接地されている。   The protection / conversion device 11a and the electrical / electronic devices 12a to 14a are connected to the external housing 10D of the shelter 10 by a common ground wire 19, and the external housing 10D is grounded at one point. Although not shown, power supply circuits such as the electric / electronic devices 12 a to 14 a are also housed in the internal casings 12 to 14, and are collectively grounded by the common ground line 19.

外線収容部１０Ｂにおける外線２１及び共通接地線１９の処理や、内線収容部１０Ｃにおける内線２２の処理には、配線分離専用のラックが用いられている。
なお、このシェルタ１０は、駅構内または信号設備や踏切設備の近辺、線路沿線など、鉄道設備の近くに設置されるものである。 A rack dedicated to wiring separation is used for processing the external line 21 and the common ground line 19 in the external line accommodating unit 10B and processing the internal line 22 in the internal line accommodating unit 10C.
The shelter 10 is installed in the vicinity of a railway facility such as in a station yard, in the vicinity of a signal facility or a railroad crossing facility, along a railway line, or the like.

この実施形態によれば、保護・変換装置１１ａ及び電気・電子機器１２ａ〜１４ａが集約されてシェルタ１０に収納されており、これらの保護・変換装置１１ａ及び電気・電子機器１２ａ〜１４ａは共通接地線１９により接地されたうえ、外部筺体１０Ｄにて一点で接地されている。また、シェルタ１０の外部筺体１０Ｄの上部に配置された受電部１５、及び、外部筺体１０Ｄの外壁または内壁を構成する高導電性材料も、共通接地線１９により一点で接地されている。
このため、仮に周辺のき電線や線路、筺体１０Ｄ等に落雷し、電気・電子機器１２ａ〜１４ａや筺体１２〜１４に過電圧が誘導されたとしても、これらは共通接地線１９により等電位接地されているため、各電気・電子機器１２ａ〜１４ａの間で電位差を生じるおそれがない。従って、過電圧により電気・電子機器１２ａ〜１４ａが故障し、破損することもない。 According to this embodiment, the protection / conversion device 11a and the electric / electronic devices 12a to 14a are collected and accommodated in the shelter 10, and the protection / conversion device 11a and the electric / electronic devices 12a to 14a are connected to a common ground. In addition to being grounded by the wire 19, it is grounded at one point by the external housing 10D. In addition, the power receiving unit 15 disposed on the upper portion of the outer casing 10D of the shelter 10 and the highly conductive material constituting the outer wall or the inner wall of the outer casing 10D are also grounded at a single point by the common ground line 19.
For this reason, even if lightning strikes the surrounding feeders and lines, the casing 10D, etc., and overvoltage is induced in the electrical / electronic devices 12a to 14a and the casings 12 to 14, they are equipotentially grounded by the common ground line 19. Therefore, there is no possibility of causing a potential difference between the electric / electronic devices 12a to 14a. Therefore, the electric / electronic devices 12a to 14a are not damaged or damaged by the overvoltage.

また、外線２１から侵入する雷サージ電流を保護・変換装置１１ａが大地に逃がし、またはバイパスすることにより、電気・電子機器１２ａ〜１４ａ側に被害が波及するのを防止することができる。
更に、シェルタ１０を、外部筺体１０Ｄの高導電性材料を介して接地したことにより、仮に受電部１５に落雷したとしても雷サージ電流が速やかに大地へ流れるので、内部の電気・電子機器１２ａ〜１４ａを確実に保護することができる。
また、外線２１、内線２２がそれぞれ外線収容部１０Ｂと内線収容部１０Ｃとに分離して収容されているので、仮に外線２１に雷サージ電流が流れた場合でも内線２２側に電圧が誘導される心配がなく、安全性を一層向上させることができる。 Moreover, it is possible to prevent damage from spreading to the electric / electronic devices 12a to 14a side by allowing the protection / conversion device 11a to escape or bypass the lightning surge current entering from the external line 21 to the ground.
Furthermore, since the shelter 10 is grounded via the highly conductive material of the external housing 10D, even if lightning strikes the power receiving unit 15, a lightning surge current flows quickly to the ground. 14a can be reliably protected.
Further, since the outer line 21 and the inner line 22 are separately accommodated in the outer line accommodating part 10B and the inner line accommodating part 10C, even if a lightning surge current flows through the outer line 21, a voltage is induced on the inner line 22 side. There is no worry and safety can be further improved.

次に、本発明の実施例を、図３〜図９を参照しつつ説明する。
図３は、図１におけるシェルタ１０に相当するシェルタ３０の構成を示したものであり、３１，３２は外部筺体を構成する銅板などの高導電性材料、３４〜３６は外部筺体を構成する鉄板などの高強度材料である。また、３３は図１の受電部１５に相当する受電部である。 Next, an embodiment of the present invention will be described with reference to FIGS.
FIG. 3 shows a configuration of a shelter 30 corresponding to the shelter 10 in FIG. 1, 31 and 32 are highly conductive materials such as copper plates constituting the outer casing, and 34 to 36 are iron plates constituting the outer casing. It is a high strength material such as. Reference numeral 33 denotes a power receiving unit corresponding to the power receiving unit 15 of FIG.

受電部３３は高導電性材料３１，３２に接続され、これらの高導電性材料３１，３２は接地システム４１により接地されている。この接地システム４１は、図１における共通接地線１９と電気的に等価なものであり、図１に示した保護・変換装置１１ａ，電気・電子機器１２ａ〜１４ａは接地システム４１にて等電位接地されている。
図４は、図３において、例えば受電部３３に落雷した時の雷サージ電流の経路を示したものであり、雷サージ電流は高抵抗の高強度材料３４〜３６には流れにくく、主として低抵抗の高導電性材料３１，３２を介して大地へ流れる。 The power receiving unit 33 is connected to the highly conductive materials 31 and 32, and these highly conductive materials 31 and 32 are grounded by the ground system 41. This grounding system 41 is electrically equivalent to the common grounding wire 19 in FIG. 1, and the protection / conversion device 11a and the electrical / electronic devices 12a to 14a shown in FIG. Has been.
FIG. 4 shows a path of lightning surge current when, for example, lightning strikes on the power receiving unit 33 in FIG. 3, and the lightning surge current hardly flows through the high-resistance high-strength materials 34 to 36, and mainly has low resistance. It flows to the ground through the highly conductive materials 31, 32.

Optical signals are exchanged between the converters 71, 72 and the outside, and the converters 71, 72 are provided. This is an example in which electrical signals are exchanged between the device 60 and the device 60.
