本考案は、水車発電装置の水量を調整する電動サーボモータ用駆動モータの冷 却装置など、操作時以外は停止してトルクだけを発生することにより負荷とのバ ランスを取っており操作時のみ回転するモータの冷却装置に関する。 The present invention balances the load by only generating torque by stopping when not operating, such as a cooling device for a drive motor for an electric servomotor that adjusts the amount of water in a turbine generator. The present invention relates to a cooling device for a rotating motor.
【０００２】[0002]
電動サーボモータ用駆動モータは、水車ガイドベーンの操作力と平衡するトル クを発生しながら拘束（一定位置にて保持）して使用する。そして、水量が増・ 減したり、系統異常が発生したときには、制御装置の指令によりこの電動サーボ モータ用駆動モータ（以下駆動モータという）が動作（回転）する。 したがって、通常の連続拘束使用では、この駆動モータは回転しないので、モ ータ温度が上昇しオーバヒートの原因となる。 このため、この駆動モータに対しては、別置の冷却装置が設備されている。 The drive motor for the electric servomotor is used while being restrained (held at a fixed position) while generating torque that balances the operating force of the turbine vane. Then, when the amount of water increases / decreases or a system abnormality occurs, the drive motor for the electric servo motor (hereinafter referred to as the drive motor) operates (rotates) according to a command from the control device. Therefore, in the normal continuous restraint use, this drive motor does not rotate, and the motor temperature rises, which causes overheating. Therefore, a separate cooling device is installed for this drive motor.
【０００３】[0003]
無人の発電所内で常時運転使用している駆動モータの冷却装置では、通風口へ のごみの混入やモータ軸受の寿命などにより、故障する場合があり、この予測が 困難である。 It is difficult to predict this because the cooling system for the drive motor, which is constantly in use in an unmanned power plant, may fail due to the inclusion of dust in the ventilation port and the life of the motor bearing.
【０００４】 また、冷却装置は、１台しか設置していないので故障した場合駆動モータのコ イル温度が上昇して使用できなくなり発電所の停止につながる。この状態は夏季 など特に電機需要が多い場合などには、大問題となりかねない。Also, since only one cooling device is installed, if it fails, the coil temperature of the drive motor rises and it becomes unusable, leading to a shutdown of the power plant. This situation can become a big problem especially in the summer when there is a large demand for electric machinery.
【０００５】 本考案は、上述の問題に鑑み駆動モータの温度上昇を防止するようにした電動 サーボモータ用駆動モータの２重冷却ファン装置の提供を目的とする。The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a double cooling fan device for a drive motor for an electric servo motor, which is configured to prevent a temperature rise of the drive motor.
【０００６】[0006]
【課題を解決するための手段】 上述の目的を達成する本考案は、電動サーボモータ用駆動モータにラジアルフ ァンとファンモータとをそれぞれ備えた第１及び第２冷却ファン装置を直列に連 通させて備え、この第１及び第２冷却ファン装置を各個独立して又は双方同時に 運転する切換手段を備えたことを特徴とする。Means for Solving the Problems The present invention to achieve the above-mentioned object is to serially connect a first and a second cooling fan device, which includes a radial fan and a fan motor, to a drive motor for an electric servomotor. It is characterized in that it is provided with a switching means for operating each of the first and second cooling fan devices independently or simultaneously.
【０００７】[0007]
第１冷却ファン装置を通常ファンとして第２冷却ファン装置を予備とし、常用 ファンの故障時に予備ファンを駆動したり、駆動モータの温度上昇により第１及 び第２冷却ファン装置を２台駆動することにより駆動モータの温度上昇が防止で きる。 The first cooling fan device is used as a normal fan and the second cooling fan device is used as a spare, and the spare fan is driven when the regular fan fails, or the first and second cooling fan devices are driven by the temperature rise of the drive motor. As a result, the temperature rise of the drive motor can be prevented.

ここで、図１，図２を参照して本考案の実施例を説明する。図１において、１ はガイドベーン等を開閉又は保持制御を行なう電動サーボモータ、２はギヤボッ クス、３は手動操作装置、４は駆動モータであるベクトル制御の誘導電動機であ る。 An embodiment of the present invention will now be described with reference to FIGS. In FIG. 1, 1 is an electric servomotor that controls the opening and closing of a guide vane or the like, 2 is a gear box, 3 is a manual operating device, and 4 is a vector control induction motor that is a drive motor.
【０００９】 この誘導電動機４には、回転検出器５及び温度リレー１１が取付けられると共 に、冷却ファン装置６，９が連通して取付けられている。 冷却ファン装置６，９には、ファンモータ７及びラジアルファン８がその内部 に備えられ、外気を吸い込む構造となっている。そして、このファンモータ７は 冷却ファン装置６にあってはスイッチＢ、冷却ファン装置９にあってはスイッチ Ａ，Ｃにより制御装置１２の制御にて駆動される。A rotation detector 5 and a temperature relay 11 are attached to the induction motor 4, and cooling fan devices 6 and 9 are attached in communication with each other. Each of the cooling fan devices 6 and 9 is provided with a fan motor 7 and a radial fan 8 therein, and has a structure for sucking outside air. The fan motor 7 is driven under the control of the controller 12 by the switch B in the cooling fan device 6 and the switches A, C in the cooling fan device 9.
【００１０】 かかる図１に示す構造にあって、常用の状態では駆動モータ４に近い第１冷却 ファン装置６を駆動し、第２冷却ファン装置９は空廻し状態で使用する。この場 合、１台の冷却ファン装置は、駆動モータ４の最大負荷の連続運転における温度 上昇に対処できる能力を有するものである。In the structure shown in FIG. 1, the first cooling fan device 6 that is close to the drive motor 4 is driven in the normal state, and the second cooling fan device 9 is used in the idle state. In this case, one cooling fan device has the capability of coping with the temperature rise in continuous operation of the maximum load of the drive motor 4.
【００１１】 冷却ファンの吸込口又は吐出口に異物が混入したり、冷却通路を半分位塞がれ たりして冷却風不足による駆動モータの温度上昇がある等、何らかの原因により 規定温度以上に温度が上昇した場合、この原因が解除されるまで２台の冷却ファ ン装置６，９を駆動すれば駆動モータの運転を円滑に継続できる。For example, the temperature of the drive motor rises due to insufficient cooling air due to foreign matter mixed into the suction port or the discharge port of the cooling fan, or the cooling passage is blocked by half the temperature. When the temperature rises, driving the two cooling fan devices 6 and 9 can continue the operation of the drive motor smoothly until the cause is eliminated.
【００１２】 また、第１冷却ファン装置６が故障した場合、温度リレー１１により第２冷却 ファン装置９に切替えられ、この第２冷却ファン装置９を駆動することにより送 風が円滑に継続されて運転が持続できる。 このような第１及び第２冷却ファン装置６，９の運転や第２冷却ファン装置９ の運転は、制御装置１２によるスイッチＡの投入やスイッチＢ，Ｃの切替えにて 行なう。When the first cooling fan device 6 fails, the temperature relay 11 switches it to the second cooling fan device 9, and by driving the second cooling fan device 9, the ventilation is smoothly continued. Driving can be continued. The operation of the first and second cooling fan devices 6 and 9 and the operation of the second cooling fan device 9 are performed by turning on the switch A and switching the switches B and C by the control device 12.
【００１３】 図２は、第１及び第２冷却ファン装置６，９による風量（Ｑ）−風圧（Ｐ）特 性を示している。この図に示すように曲線２１は２台の冷却ファン装置６，９を 駆動させた場合の特性であり、曲線２２は第１冷却ファン装置６のみを駆動させ 第２冷却ファン装置９を取外した特性であり、曲線２３は第１冷却ファン装置６ のみを駆動させ第２冷却ファン装置９を空廻しさせた特性であり、そして曲線２ ４は第１及び第２冷却ファン装置６，９のうち一方を停止し他方を駆動した場合 の特性である。FIG. 2 shows air volume (Q) -air pressure (P) characteristics of the first and second cooling fan devices 6 and 9. As shown in this figure, the curve 21 is the characteristic when two cooling fan devices 6 and 9 are driven, and the curve 22 is only the first cooling fan device 6 is driven and the second cooling fan device 9 is removed. The curve 23 is a characteristic in which only the first cooling fan device 6 is driven and the second cooling fan device 9 is idle, and the curve 24 is a characteristic of the first and second cooling fan devices 6 and 9. This is the characteristic when one is stopped and the other is driven.
【００１４】 駆動モータ４が何らかの原因により温度上昇した場合、第１及び第２冷却ファ ン装置６，９の２台を駆動する。この場合Ｑ−Ｐ特性の極性の曲線２１にて定格 ポイントではＢポイントの風量で冷却する。これにより原因が解除するまで２台 駆動とし、解除後は再び１台駆動として運転を円滑に継続できる。When the temperature of the drive motor 4 rises for some reason, the first and second cooling fan devices 6 and 9 are driven. In this case, cooling is performed with the air volume of B point at the rated point on the curve 21 of the polarity of the QP characteristic. As a result, two units will be driven until the cause is resolved, and once it is released, one unit will be driven again and the operation can be continued smoothly.
【００１５】 常用ファンとして第１冷却ファン装置６を用い、第２冷却ファン装置９を予備 とするのは、第１冷却ファンの駆動にて第２冷却ファン空廻しの方が実験上つれ 廻り回転数が少ないことによる。 実験としては、ファンモータの定格として0.45kw、４極、６０Hz，1800rpm を 用い、第１冷却装置６を1600rpm にて運転したとき第２冷却ファン装置９が空廻 り状態でほとんど回転しないのに対し、第２冷却ファン装置９を1600rpm に運転 したとき第１冷却ファン装置６が空廻り状態で350rpmにて回転した。したがって 、前者の方が第２冷却ファンの空回転少なくグリース寿命、ベアリング寿命を短 縮することがない。The reason why the first cooling fan device 6 is used as the regular fan and the second cooling fan device 9 is used as a spare is that the first cooling fan is driven and the second cooling fan is rotated around as a result of experiments. Due to the small number. As an experiment, the fan motor was rated at 0.45kw, 4 poles, 60Hz, 1800rpm, and when the first cooling device 6 was operated at 1600rpm, the second cooling fan device 9 hardly rotated in the idle state. On the other hand, when the second cooling fan device 9 was operated at 1600 rpm, the first cooling fan device 6 was rotated at 350 rpm in the idle state. Therefore, in the former case, the idle rotation of the second cooling fan is less and the grease life and the bearing life are not shortened.
【００１６】 常用の第１冷却ファン装置６が故障した場合、温度リレー１１にて検知し、第 ２冷却ファン装置９を駆動し冷却する。 また、第１冷却ファン装置６が停止して動かない状態では、第２冷却ファン装 置９を駆動した場合、曲線２４の如く風量が減少するがモータ冷却の設計ポイン トをＣポイントとして運転を継続できる。When the regular first cooling fan device 6 fails, the temperature relay 11 detects it and drives the second cooling fan device 9 to cool it. Further, when the second cooling fan device 9 is driven when the first cooling fan device 6 is stopped and does not move, the air volume decreases as shown by the curve 24, but the operation is performed with the motor cooling design point as the C point. I can continue.

以上説明したように本考案によれば、駆動モータの温度上昇を検知して冷却フ ァン装置の１台駆動から２台駆動とすることができて冷却を大幅に向上でき、ま た、常用の冷却ファン装置が故障した場合自動的に予備のものに切替えることが でき、駆動モータの温度上昇や運転停止を防止できる。 As described above, according to the present invention, the temperature rise of the drive motor can be detected and the cooling fan device can be driven from one drive to two drives, and the cooling can be greatly improved. When the cooling fan device of the above fails, it can be automatically switched to the spare one, and the temperature rise of the drive motor and the operation stop can be prevented.
