特許文献１では原子炉制御棒駆動装置用の無停電電源装置は１台であるが、図３に例示のように、必要容量の無停電電源装置２台で構成することが必要である。
一方、通常の一般的な蓄電池は水素ガスを発生する、蓄電池容量が火災予防条例（蓄電池設備（定格容量と電槽数の積の合計が4800Ah未満のものを除く。）の電槽は、遮光措置を講じ、温度変化が急激でないところで、かつ、耐酸性の床上又は台上に、転倒しないように設けなければならない。）での規制対象となり、設置環境が厳しく制限され、既設原子力プラントにコンバータとインバータと蓄電池とで構成された無停電電源装置を原子炉制御棒駆動装置用の電源として適用する場合は外気との直接換気は難しく、コンバータとインバータと蓄電池とで構成された無停電電源装置を原子炉制御棒駆動装置用の電源として適用するに当たっての障壁となり、その対策として、温度が急変しないように空調設備を別途設ける必要が生じる等の問題が生じ、また、コンバータとインバータと蓄電池とで構成された無停電電源装置を２台設置した場合は当該問題点も増大する等の更なる問題が生じる。 In Patent Document 1, there is one uninterruptible power supply for the reactor control rod drive device, but it is necessary to configure with two uninterruptible power supply devices with the required capacity as illustrated in FIG.
On the other hand, the ordinary general storage battery generates hydrogen gas, and the battery capacity of the storage battery is a fire prevention ordinance (except for batteries with storage battery equipment (the sum of the product of the rated capacity and the number of battery cases is less than 4800Ah). Measures must be taken so that the temperature does not change rapidly and must be installed on an acid-resistant floor or table so as not to fall.) The installation environment is severely restricted, and the converter is installed in an existing nuclear power plant. When applying an uninterruptible power supply composed of inverter, inverter and storage battery as power source for reactor control rod drive device, direct ventilation with outside air is difficult, uninterruptible power supply composed of converter, inverter and storage battery As a power source for the reactor control rod drive system, and as a countermeasure against this, it is necessary to provide a separate air conditioning facility so that the temperature does not change suddenly. Occurs, When it is installed two uninterruptible power supply constituted by the converter and the inverter and battery further problem such that even the problems increase occurs.

この発明は、前述のような実情に鑑みてなされたもので、火災予防条例の対象外とすることが可能な原子炉制御棒駆動装置用無停電電源装置を提供することを目的とするものである。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an uninterruptible power supply for a reactor control rod drive that can be excluded from the fire prevention regulations. is there.

この発明に係る原子炉制御棒駆動装置用無停電電源装置は、入力された交流を直流に変換して直流を出力するコンバータ、前記コンバータの直流出力を平滑する平滑コンデンサ、前記平滑コンデンサによって平滑された直流を入力し当該直流を交流に変換して交流を出力するインバータ、及び前記平滑された直流によって充電され前記入力交流が停電すると前記インバータの入力に直流電力を供給する停電時給電用のコンデンサを備えたものである。   An uninterruptible power supply for a reactor control rod drive device according to the present invention is smoothed by a converter that converts input AC to DC and outputs DC, a smoothing capacitor that smoothes the DC output of the converter, and the smoothing capacitor. An inverter that inputs a direct current, converts the direct current to alternating current and outputs the alternating current, and a capacitor for power supply during a power failure that is charged by the smoothed direct current and supplies direct current power to the input of the inverter when the input alternating current fails It is equipped with.

この発明は、入力された交流を直流に変換して直流を出力するコンバータ、前記コンバータの直流出力を平滑する平滑コンデンサ、前記平滑コンデンサによって平滑された直流を入力し当該直流を交流に変換して交流を出力するインバータ、及び前記平滑された直流によって充電され前記入力交流が停電すると前記インバータの入力に直流電力を供給する停電時給電用のコンデンサを備えているので、火災予防条例の対象外とすることが可能な原子炉制御棒駆動装置用無停電電源装置を提供する効果がある。   This invention converts the input alternating current into direct current and outputs direct current, the smoothing capacitor that smoothes the direct current output of the converter, the direct current smoothed by the smoothing capacitor is input, and the direct current is converted into alternating current. Since it is equipped with an inverter that outputs alternating current, and a capacitor for power supply during a power failure that supplies DC power to the input of the inverter when the input alternating current is charged by the smoothed direct current and fails, it is not subject to the fire prevention regulations.

実施の形態１．
以下、この発明の実施の形態１を図１に基づいて説明する。
図１において、第１および第２の無停電電源装置１Ａ，１Ｂは、何れも交流を直流に変換するコンバータ１１、直流を交流に変換するインバータ１２、瞬低が発生した時に電力を供給するための二層タイプの停電時給電用のコンデンサである通称ＥＤＬＣ（Electric
Double Layer Capacitor）１３、および直流電圧を平滑するための平滑コンデンサ１４
で構成されている。 Embodiment 1 FIG.
A first embodiment of the present invention will be described below with reference to FIG.
In FIG. 1, the first and second uninterruptible power supply devices 1A and 1B both supply a converter 11 that converts alternating current to direct current, an inverter 12 that converts direct current to alternating current, and supplies power when a sag occurs. Commonly known as EDLC (Electric)
Double Layer Capacitor) 13 and smoothing capacitor 14 for smoothing the DC voltage
It consists of

第１および第２の無停電電源装置１Ａ，１Ｂは並列運転され、その出力交流電力は、周知のように原子炉トリップ遮断器２を経由して制御棒駆動装置３に供給される。並列運転される第１および第２の無停電電源装置１Ａ，１Ｂはそれぞれ必要な負荷容量を２分の１ずつ分担することになる。   The first and second uninterruptible power supply units 1A and 1B are operated in parallel, and the output AC power is supplied to the control rod drive unit 3 via the reactor trip breaker 2 as is well known. The first and second uninterruptible power supply devices 1A and 1B that are operated in parallel each share a necessary load capacity by a half.

蓄電池の代替品として、ＥＤＬＣを使用することにより、水素ガスが発生しなくなり火災予防条例の規制対象から外れるため、図１の電源構成で使用可能。
また、ＥＤＬＣの特徴として、内部抵抗が低く短時間で充放電が可能であり、蓄電効率が著しく高く、コンバータ１１およびインバータ１２と組み合わせることによって原子炉制御棒駆動装置用無停電電源装置を構成した場合、瞬低が発生した時にも電力を原子炉制御棒駆動装置に継続的に供給する原子炉制御棒駆動装置用無停電電源装置として好適である。 By using EDLC as an alternative to storage batteries, hydrogen gas is no longer generated and the product is no longer subject to the fire prevention regulations.
In addition, as a feature of EDLC, the internal resistance is low, charging / discharging is possible in a short time, the storage efficiency is remarkably high, and the uninterruptible power supply for the reactor control rod drive device is configured by combining with the converter 11 and the inverter 12 In this case, it is suitable as an uninterruptible power supply for a reactor control rod drive device that continuously supplies power to the reactor control rod drive device even when a sag occurs.

なお、ＥＤＬＣを使用することで、出力密度が高く大電流充放電が可能になるが、蓄電池に比べて蓄電圧が低く、補償時間が短いが、コンバータとインバータとで構成される無停電電源装置には電圧低下補償用のチョッパ回路（図示省略）が付帯的に常設されているので、放電時電圧低下にも対応でき、これにより制御棒駆動電源に対する瞬時停電要求である１秒にも充分対応可能である。また、ＥＤＬＣ充放電回路、電圧低下補償用のチョッパ回路の何れも、従来の蓄電池を使用したバッテリー方式の無停電電源装置のものを、そのまま使用可能である。   The use of EDLC makes it possible to charge and discharge a large current with a high output density, but the storage voltage is lower than that of the storage battery and the compensation time is short. Since a voltage drop compensation chopper circuit (not shown) is permanently installed in the, it can cope with a voltage drop during discharge, which is sufficient for an instant power failure request to the control rod drive power supply for 1 second. Is possible. In addition, any of the EDLC charge / discharge circuit and the voltage drop compensation chopper circuit can use a conventional battery type uninterruptible power supply using a storage battery.

実施の形態２．
前述の実施の形態１では第１および第２の無停電電源装置１Ａ，１Ｂの各々に個別に１台のＥＤＬＣを接続した場合を例示したが、ＥＤＬＣは、蓄電池と比較するとコストが上がると考えられることから、本実施の形態２では、図２に例示のように、１台のＥＤＬＣを第１および第２の無停電電源装置１Ａ，１Ｂに共用するように接続すれば廉価になり、さらに、図２に例示のように、第１および第２の無停電電源装置１Ａ，１Ｂを個別に盤内に内蔵せずに１個の盤、即ち共通の盤（無停電電源盤）４に第１および第２の無停電電源装置１Ａ，１Ｂを内蔵すれば、盤面数が減ることに加えて、第１および第２の無停電電源
装置１Ａ，１Ｂに空調設備も共用化できるので、据付面積が小さくなり、低コスト化も図れる。 Embodiment 2. FIG.
In the first embodiment described above, the case where one EDLC is individually connected to each of the first and second uninterruptible power supply devices 1A and 1B is exemplified. However, EDLC is considered to increase costs as compared with a storage battery. Therefore, in the second embodiment, as shown in FIG. 2, if one EDLC is connected so as to be shared by the first and second uninterruptible power supply devices 1A and 1B, the cost is reduced. As shown in FIG. 2, the first and second uninterruptible power supply units 1A and 1B are not individually built in the panel, but are integrated into one panel, that is, a common panel (uninterruptible power panel) 4. If 1 and 2 uninterruptible power supplies 1A and 1B are built in, in addition to reducing the number of panels, the first and second uninterruptible power supplies 1A and 1B can share air-conditioning equipment. Can be reduced and the cost can be reduced.

なお、本発明は、その発明の範囲内において、各実施の形態を適宜、変形、省略することができる。
なお、各図中、同一符合は同一または相当部分を示す。 In the present invention, each embodiment can be appropriately modified or omitted within the scope of the invention.
