Description

本発明は、地震発生時に、変圧器が転倒するのを防止するための技術に関し、詳しくは、比較的小型の装置で、大型の変圧器の転倒を確実に防止できる手段を提供することを目的とする。   The present invention relates to a technique for preventing a transformer from overturning in the event of an earthquake, and more particularly, to provide means capable of reliably preventing a large transformer from overturning with a relatively small device. And

変圧器は、トランスや変成器とも称され、電力会社から供給される高電圧（例えば６６００Ｖ）の電気を、低電圧（１００−２００Ｖ）に降圧させる電力機器であり、ビルや工場等に数多く設置されている。   Transformers, also called transformers and transformers, are power devices that step down high-voltage (eg 6600V) electricity supplied by electric power companies to low-voltage (100-200V) and are installed in many buildings and factories. Has been.

従来、変圧器が設置される架台と床面との間に、防振ゴム等の防振材を配置して、変圧器を弾性支持することが行われている。すなわち、変圧器が設置される架台の下面に防振ゴムなどより成る防振材を配置し、この防振材を介して架台を床面に設置している。この構成により、変圧器から発生する振動騒音を防振材で吸収し、床面への伝播を遮断している。また防振材は、地震発生時には床面の振動を吸収し、変圧器が過度に振動するのを防止する機能を有する。   Conventionally, vibration isolating materials such as vibration isolating rubber are disposed between a gantry on which a transformer is installed and a floor surface to elastically support the transformer. That is, a vibration-proof material made of vibration-proof rubber or the like is disposed on the lower surface of the gantry on which the transformer is installed, and the gantry is installed on the floor via the vibration-proof material. With this configuration, vibration noise generated from the transformer is absorbed by the vibration isolator, and the propagation to the floor surface is blocked. The vibration isolator absorbs floor vibration when an earthquake occurs and has a function of preventing the transformer from excessive vibration.

特開平８−８１２２号公報JP-A-8-8122

変圧器は、一般に塔状比（変圧器の高さ÷幅）が約５程度と非常に大きいことから、地震時の振動エネルギーを受けると変圧器の上部が回転方向へ揺動し、変圧器が転倒するおそれがある。また変圧器には、耐震ストッパが設置されるが、大地震時に架台が大きく揺れた場合、特に、変圧器の振動周波数が、地震の共振周波数域と一致した場合には揺れが大きく増幅され、変圧器の転倒を招くおそれがある。   Transformers generally have a very large tower ratio (transformer height ÷ width) of about 5, so when receiving vibration energy during an earthquake, the upper part of the transformer swings in the direction of rotation. May fall over. In addition, the transformer is equipped with an earthquake-resistant stopper, but when the base shakes greatly during a large earthquake, especially when the vibration frequency of the transformer matches the resonance frequency range of the earthquake, the vibration is greatly amplified, There is a risk of overturning the transformer.

本発明は、従来の上記問題を解決するために案出されたものであり、変圧器をワイヤで支持する支持手段によって、地震により変圧器が転倒するのを確実に防止できる転倒防止装置の提供を目的としている。   The present invention has been devised to solve the above-described conventional problems, and provides an overturn prevention device that can reliably prevent the transformer from toppling over due to an earthquake by means of supporting the transformer with wires. It is an object.

請求項１に係る本発明は、変圧器の近傍に立設される支柱と、支柱に設けられ、回転自在な回転部と、回転部の回転に対し制動力を作用させる制動手段とを有する滑車部材と、支柱の基部の近傍に一端が固定される弾性体と、一端部が変圧器に取り付けられ、他端部が弾性体に取り付けられ、中間部分が滑車部材の各回転部に沿って配設されるワイヤとを備える支持手段を含むことを特徴とする変圧器の転倒防止装置である。   The present invention according to claim 1 is a pulley having a support column installed in the vicinity of the transformer, a rotatable rotation unit provided on the support column, and a braking means for applying a braking force to the rotation of the rotation unit. A member, an elastic body whose one end is fixed in the vicinity of the base of the column, one end is attached to the transformer, the other end is attached to the elastic body, and an intermediate portion is arranged along each rotating part of the pulley member. It is a transformer fall prevention device characterized by including a support means provided with an installed wire.

請求項２に係る本発明は、前記滑車部材が前記支柱に複数個設けられる請求項１に記載する変圧器の転倒防止装置である。   The present invention according to claim 2 is the overturn prevention device for a transformer according to claim 1, wherein a plurality of the pulley members are provided on the support column.

請求項３に係る本発明は、前記支持手段が、変圧器の周囲の４箇所に配置される請求項１または２に記載の変圧器の転倒防止装置である。 The present invention according to claim 3 is the transformer overturn prevention device according to claim 1 or 2, wherein the support means is arranged at four locations around the transformer.

請求項４に係る本発明は、前記変圧器が、免震手段または防振手段の上に設置されている請求項１−３のいずれか１項に記載の変圧器の転倒防止装置である。   The present invention according to claim 4 is the overturn prevention device for a transformer according to any one of claims 1 to 3, wherein the transformer is installed on a seismic isolation means or a vibration isolation means.

請求項５に係る本発明は、前記弾性体がコイルばねである請求項１−４のいずれか１項に記載の変圧器の転倒防止装置である。 According to a fifth aspect of the present invention, in the transformer overturn prevention device according to any one of the first to fourth aspects, the elastic body is a coil spring.

請求項１に係る本発明の転倒防止装置は、変圧器の近傍に立設される支柱と、支柱に設けられ、回転自在な回転部と、回転部の回転に対し制動力を作用させる制動手段とを有する滑車部材と、支柱の基部の近傍に一端が固定される弾性体と、一端部が変圧器に取り付けられ、他端部が弾性体に取り付けられ、中間部分が滑車部材の各回転部に沿って配設されるワイヤとを備える支持手段を用いるので、変圧器は、他端部が弾性体に取り付けられたワイヤによって常時引っ張り方向に付勢される。地震により変圧器が振動したときには、ワイヤの他端部に取り付けた弾性体の弾性力と、滑車部材の制動手段とによって、変圧器の変位が抑制されるので、変圧器の転倒を確実に防止できる。また、弾性体と滑車部材以外にダンピング要素を必要としないので、構造を簡単にすることができ、低価格で、確実な転倒防止効果を得ることができる。
また変圧器と滑車部材との間のワイヤを水平方向に張架することができるので、変圧器の水平方向の振動を抑止することが可能である。 According to a first aspect of the present invention, there is provided an overturn prevention device according to the present invention, comprising: a support column installed in the vicinity of the transformer; a rotation unit provided on the support column; and a rotatable rotating unit; A pulley member having one end fixed in the vicinity of the base of the support column, one end is attached to the transformer, the other end is attached to the elastic body, and an intermediate portion is each rotating part of the pulley member. Therefore, the transformer is always urged in the pulling direction by the wire having the other end attached to the elastic body. When the transformer vibrates due to an earthquake, the displacement of the transformer is suppressed by the elastic force of the elastic body attached to the other end of the wire and the braking means of the pulley member, thus preventing the transformer from falling over. it can. Further, since no damping element is required other than the elastic body and the pulley member, the structure can be simplified, and a reliable fall prevention effect can be obtained at low cost.
Further, since the wire between the transformer and the pulley member can be stretched in the horizontal direction, it is possible to suppress the horizontal vibration of the transformer.

請求項２に係る本発明によれば、前記滑車部材が前記支柱に複数個設けられるので、地震発生時に変圧器が変位することによりワイヤに作用する加重は、複数個の滑車部材によって分散して支持される。そのため、１個当たりの滑車部材に作用する加重を小さくできるから、滑車部材を小型化することが可能である。その結果、変圧器の周囲に設置する支持手段も小型化できるので、変圧器が収納されるキュービクル内において、本発明を実施することが可能である。 According to the second aspect of the present invention, since the plurality of pulley members are provided on the column, the load acting on the wire due to the displacement of the transformer when an earthquake occurs is dispersed by the plurality of pulley members. Supported. Therefore, since the load acting on each pulley member can be reduced, the pulley member can be reduced in size. As a result, since the supporting means installed around the transformer can also be reduced in size, the present invention can be implemented in a cubicle in which the transformer is accommodated.

請求項３に係る本発明によれば、前記支持手段が、変圧器の周囲の４箇所に配置されるので、変圧器の変位を確実に抑止することができる。 According to the third aspect of the present invention, since the support means is arranged at four locations around the transformer, the displacement of the transformer can be reliably suppressed.

請求項４に係る本発明によれば、前記変圧器が、免震手段または防振手段の上に設置されているので、地震発生時における変圧器の振動の抑止効果が高いため、支持手段をより小型化することが可能である。 According to the fourth aspect of the present invention, since the transformer is installed on the seismic isolation means or the vibration isolating means, the effect of suppressing the vibration of the transformer at the time of occurrence of the earthquake is high. It is possible to further reduce the size.

請求項５に係る本発明によれば、前記弾性体がコイルばねであるので、バネ定数を小さく設定することにより、固有振動数を低下させることができる。その結果、変圧器の振動加速度を非常に小さくできるので、比較的小型の装置でも、確実な転倒防止機能を発揮することができる。 According to the present invention of claim 5, since the elastic body is a coil spring, the natural frequency can be lowered by setting the spring constant small. As a result, the vibration acceleration of the transformer can be made very small, and a reliable fall prevention function can be exhibited even with a relatively small device.

It is.

変圧器Ｔは、ビルや工場等に設置され、電力会社から供給される例えば６６００Ｖ等の高電圧を電磁誘導を利用して、１００Ｖや２００Ｖの電圧に降圧させる電力機器であり、機器内部に図示しないコイル等が収納されている。変圧器Ｔは、床部２２上に、防振手段としてゴムなどから成る防振材２１を配置し、この防振材２１を介して配置した架台２０上に設置される。防振材２１によって、変圧器Ｔを弾性的に支持し、駆動時に発生する上下方向の振動を吸収する。また防振材２１は、地震発生時の振動を緩和する機能も有する。なお、設置の状況に応じ、防振材２１は省略が可能である。   The transformer T is a power device that is installed in a building, a factory, or the like and steps down a high voltage such as 6600 V supplied from an electric power company to a voltage of 100 V or 200 V using electromagnetic induction, and is illustrated inside the device. The coil etc. which do not do are stored. The transformer T is disposed on a floor 20 on which a vibration isolating material 21 made of rubber or the like is disposed as a vibration isolating means on the floor portion 22 and is disposed via the vibration isolating material 21. The vibration isolator 21 elastically supports the transformer T and absorbs vertical vibration generated during driving. The vibration isolator 21 also has a function of mitigating vibration when an earthquake occurs. The vibration isolator 21 can be omitted depending on the installation situation.

本例の変圧器Ｔの転倒防止装置Ｓは、変圧器Ｔの周囲４箇所に配置した、４つの支持手段１０から構成される。支持手段１０は、変圧器Ｔの近傍に立設される支柱１１と、支柱１１に設けられる複数個の滑車部材１２と、支柱１１の基部の近傍に一端が固定されるコイルばねなどから成る弾性体１４と、一端部が変圧器Ｔの取付部３０に取り付けられ、他端部が弾性体１４に取り付けられ、中間部分が複数個の滑車部材１２に沿って配設されるワイヤ１３とを備える。支持手段１０の設置数は、適用する変圧器Ｔの大きさや使用状況等に応じて適宜変更可能である。ただし、変圧器Ｔに対し、左右または前後方向に対称に支持手段１０を配置することが望ましい。   The overturn prevention device S of the transformer T of this example is composed of four support means 10 arranged at four locations around the transformer T. The support means 10 is composed of a column 11 erected in the vicinity of the transformer T, a plurality of pulley members 12 provided in the column 11, and a coil spring whose one end is fixed near the base of the column 11. And a wire 13 having one end attached to the attachment portion 30 of the transformer T, the other end attached to the elastic body 14, and an intermediate portion disposed along the plurality of pulley members 12. . The number of installation of the support means 10 can be appropriately changed according to the size of the transformer T to be applied, the usage situation, and the like. However, it is desirable to arrange the support means 10 symmetrically with respect to the transformer T in the left-right or front-back direction.

支柱１１は、本例では長尺な角パイプで構成され、下端部に取着した架台プレート１５を床部２２へボルトまたは溶接によって固定することによって立設される。   In this example, the column 11 is formed of a long square pipe, and is erected by fixing the gantry plate 15 attached to the lower end to the floor 22 by bolts or welding.

滑車部材１２は、本例では、支柱の上端に近い方の領域に、複数個が互いに隣接するように取り付けられる。滑車部材１２は、中央部の回転自在な回転部１２ａと、回転部１２ａを挟持する固定部１２ｂと、回転部１２ａの回転に対し制動力を作用させる制動手段とを含む。制動手段には、たとえばロータリーダンパなどの構成が利用される。すなわち、回転部１２ａの回転軸が収納されるケース内に、シリコンオイルなどの粘性流体が充填され、回転部１２ａには、粘性流体との接触面積を大きくするための構造が設けられる。回転部１２ａは、回転する際に粘性流体から抵抗を受けるため、回転部１２ａの回転に対し制動力を作用させることができる。 In this example, the pulley member 12 is attached to a region closer to the upper end of the support so that a plurality of the pulley members 12 are adjacent to each other. The pulley member 12 includes a rotatable part 12a that is rotatable at the center, a fixed part 12b that sandwiches the rotating part 12a, and a braking means that applies a braking force to the rotation of the rotating part 12a. For the braking means, for example, a structure such as a rotary damper is used. That is, a viscous fluid such as silicone oil is filled in a case in which the rotating shaft of the rotating part 12a is accommodated, and the rotating part 12a is provided with a structure for increasing the contact area with the viscous fluid. Since the rotating part 12a receives resistance from the viscous fluid when rotating, a braking force can be applied to the rotation of the rotating part 12a.

複数の滑車部材１２は、回転部１２ａの回転軸が、互いに平行となるように配置される。各滑車部材１２は、固定部１２ｂをブラケット１６やアーム１７などで支柱１１へ連結することによって、取り付けられる。本例では、１本の支柱１１あたり４個の滑車部材１２を設けているが、この個数は適宜変更可能である。すなわち、１個でも、２−３個でもよく、５個以上でもよい。なお、支柱１１に設ける滑車部材１２を１個だけとする場合、ワイヤ１３を、回転部１２ａの周面に１周巻き付けてもよい。 The plurality of pulley members 12 are arranged such that the rotation axes of the rotating portion 12a are parallel to each other. Each pulley member 12 is attached by connecting the fixing portion 12b to the support column 11 with a bracket 16 or an arm 17 or the like. In this example, four pulley members 12 are provided for each column 11, but this number can be changed as appropriate. That is, it may be one, 2-3, or 5 or more. In addition, when only one pulley member 12 is provided on the column 11, the wire 13 may be wound around the circumferential surface of the rotating portion 12a.

最上部の滑車部材１２の高さ位置は、変圧器Ｔにおける取付部３０が設けられる上面部と同じ高さか、または上面部よりも高い位置となるように配置して、変圧器Ｔと滑車部材１２との間のワイヤ１３がなるべく水平となるように設定することが望ましい。 The uppermost pulley member 12 is arranged such that the height position of the uppermost pulley member 12 is the same as or higher than the upper surface portion of the transformer T where the mounting portion 30 is provided. It is desirable to set the wire 13 between the wires 12 to be as horizontal as possible.

支柱１１の基部付近には、弾性体１４が配設される。本例では、架台プレート１５に一端を固定したコイルばねが弾性体１４として使用される。コイルばねは、そのばね定数を適宜設定することによって、変圧器Ｔの振動や変位に対する挙動を制御することが可能である。なお、コイルばねに代えて、ゴムなどの弾性樹脂を使用することも可能である。 An elastic body 14 is disposed near the base of the column 11. In this example, a coil spring having one end fixed to the gantry plate 15 is used as the elastic body 14. The coil spring can control the behavior of the transformer T against vibration and displacement by appropriately setting the spring constant. It is also possible to use an elastic resin such as rubber instead of the coil spring.

ワイヤ１３は、その一端部が、変圧器Ｔの上面部に設けた適宜の取付部３０に接続され、他端部が弾性体１４に接続され、中間部は、複数の滑車部材１２の各回転部１２ａの表面に沿うように配置される。 One end portion of the wire 13 is connected to an appropriate mounting portion 30 provided on the upper surface portion of the transformer T, the other end portion is connected to the elastic body 14, and an intermediate portion is connected to each of the plurality of pulley members 12. It arrange | positions along the surface of the part 12a.

このように構成される本発明の転倒防止装置Ｓは、変圧器Ｔの上面部と、支柱１１の基部付近に固定した弾性体１４とを、滑車部材１２の回転部１２ａ表面を接触して通過するワイヤ１３で連結したので、地震発生によって変圧器Ｔに振動や変位が生じたときに、この振動や変位を、ワイヤ１３を介する弾性体１４の弾性変形と、滑車部材１２の制動力とによって吸収し、変圧器Ｔの振動および変位を抑止する。 The fall prevention device S of the present invention configured as described above passes the upper surface portion of the transformer T and the elastic body 14 fixed in the vicinity of the base portion of the support column 11 in contact with the surface of the rotating portion 12a of the pulley member 12. When the transformer T is vibrated or displaced due to the occurrence of an earthquake, the vibration or displacement is caused by the elastic deformation of the elastic body 14 via the wire 13 and the braking force of the pulley member 12. Absorbs and suppresses the vibration and displacement of the transformer T.

支柱１１に設けた滑車部材１２およびワイヤ１３と、弾性体１４とからなる簡素な構成なので、低価格で、効果の確実な転倒防止装置Ｓを提供することができる。 Since it is a simple structure consisting of the pulley member 12 and the wire 13 provided on the support column 11 and the elastic body 14, it is possible to provide a fall-preventing device S having a certain effect at low cost.

複数の滑車部材１２を設けることによって、変圧器Ｔの振動時にワイヤ１３に作用する荷重を、各滑車部材１２によって分散して支持することが可能となる。それ故、滑車部材１２の一つ当たりの負担が小さくなるので、滑車部材１２を小型化することが可能である。また、滑車部材１２の小型化により、支持手段１０も小型化されるので、本発明の転倒防止装置Ｓはコンパクト化が可能であり、変圧器Ｔが収納されるキュービクルなどの内部に一緒に収納することが可能となる。 By providing the plurality of pulley members 12, the load acting on the wire 13 when the transformer T vibrates can be dispersed and supported by each pulley member 12. Therefore, since the load per pulley member 12 is reduced, the pulley member 12 can be reduced in size. Since the support member 10 is also downsized due to the downsizing of the pulley member 12, the overturn prevention device S of the present invention can be downsized and stored together in a cubicle or the like in which the transformer T is stored. It becomes possible to do.

また本例の転倒防止装置Ｓは、支持手段１０を変圧器Ｔの左右両側に配置するとともに、変圧器Ｔの上面部から支持手段１０へ延びるワイヤ１３の張架方向をほぼ水平に設定した。この構成により、変圧器Ｔの上部がワイヤ１３で左右に水平方向へ引っ張られた状態に支持されるから、変圧器Ｔの水平方向の振動や変位を抑止することができる。しかも、ワイヤ１３の張架方向を滑車部材１２によって鉛直方向に変更しているので、支柱１１を変圧器Ｔの近傍に配置することができる。よって、転倒防止装置Ｓのコンパクト化が容易である。 Further, in the fall prevention device S of this example, the support means 10 is disposed on both the left and right sides of the transformer T, and the stretching direction of the wire 13 extending from the upper surface portion of the transformer T to the support means 10 is set to be substantially horizontal. With this configuration, the upper portion of the transformer T is supported in a state of being pulled horizontally in the left and right directions by the wire 13, so that horizontal vibration and displacement of the transformer T can be suppressed. Moreover, since the stretching direction of the wire 13 is changed to the vertical direction by the pulley member 12, the support column 11 can be disposed in the vicinity of the transformer T. Therefore, it is easy to make the overturn prevention device S compact.

なお、弾性体１４をコイルばねとしたときは、ばね定数を小さく設定することにより、固有振動数が低下するので、変圧器Ｔの振動時にワイヤ１３を通じて生じる弾性体（コイルばね）１４の振動速度を小さくすることができる。その結果、地震発生時の変圧器Ｔの振動を遅くできる効果が得られる。 When the elastic body 14 is a coil spring, the natural frequency is lowered by setting the spring constant to be small. Therefore, the vibration speed of the elastic body (coil spring) 14 generated through the wire 13 when the transformer T vibrates. Can be reduced. As a result, an effect of slowing down the vibration of the transformer T when an earthquake occurs can be obtained.

本発明は、変電所や、工場などの大電力を使用する施設に設置される変圧器が、地震発生時に振動で転倒するのを確実に防止することができる。変圧器Ｔの大きさに応じて、支持手段１０を構成する滑車部材１２の個数や、支持手段１０の設置数を最適なように変更することが容易である。さらに、変圧器に類似する構造物への応用も可能である。   The present invention can reliably prevent a transformer installed in a substation or a facility that uses high power, such as a factory, from falling over due to vibration when an earthquake occurs. Depending on the size of the transformer T, it is easy to change the number of pulley members 12 constituting the support means 10 and the number of support means 10 to be optimized. Further, it can be applied to a structure similar to a transformer.
