Description

この発明は、原子炉（例えば加圧水型原子炉）の熱出力の制御及び原子炉の停止に使用する制御棒の制御装置の機能および性能を確認する試験に使用する模擬負荷装置に関するものである。   The present invention relates to a simulated load device used for a test for confirming the function and performance of a control device for a control rod used for controlling the thermal output of a nuclear reactor (for example, a pressurized water reactor) and shutting down the nuclear reactor.

従来の制御棒制御装置の模擬負荷装置は、負荷に原子力プラントの制御棒駆動機構に使用しているコイルと同一のコイルを適用している。実機のコイルは、原子炉の頂部に設置する制御棒駆動機構に内蔵するものであることから、温度と放射線に対する高い耐環境性を有する仕様としているため、構成材料が特殊であり、製造コストが高く、部材の調達に長い期間を要するという問題点がある。そのため、プラント個別に設置するためには非常に高額な投資が必要となることから、プラント間で共用する運用としており、定期検査ごとにプラント間を移動する作業が必要となり、重量物の運搬作業が定期検査の都度発生するという問題点がある。   In the conventional simulated load device of the control rod control device, the same coil as that used in the control rod drive mechanism of the nuclear power plant is applied to the load. Since the actual coil is built in the control rod drive mechanism installed at the top of the nuclear reactor, it has specifications that have high environmental resistance to temperature and radiation. There is a problem that it takes a long time to procure parts. For this reason, a very expensive investment is required to install individual plants, so operations are shared between plants, and it is necessary to move between plants for each periodic inspection. There is a problem that occurs every time of periodic inspection.

また、制御棒制御装置は、制御棒駆動コイルの通電電流を一定値に制御する装置であり、その性能、すなわち、電流制御の安定性は、制御棒制御装置の負荷であるコイルの通電電流を計測することにより確認することができる。この電流計測のためには、コイルの通電ラインを解線して電流計を接続するという作業をコイルの個数分繰り返すことが必要となり、作業量が多いという問題点がある。   The control rod controller is a device that controls the energization current of the control rod drive coil to a constant value, and its performance, that is, the stability of current control, is based on the current flowing through the coil that is the load of the control rod control device. This can be confirmed by measuring. For this current measurement, it is necessary to repeat the work of disconnecting the energization line of the coil and connecting the ammeter as many times as the number of coils, resulting in a large amount of work.

また、制御棒駆動コイルの抵抗値は周囲温度によって変化するため、高温条件での機能確認試験を行う場合、コイルに長時間連続通電し自己発熱によって規定の温度まで温度上昇させる必要があるため、試験に時間を要し、試験時の消費電力が多いという問題点がある。また、模擬負荷装置が高額であるため、必要最低限の模擬負荷しか準備できないことから、制御棒制御装置の全ての電流制御回路の機能を確認するためには、模擬負荷の接続、解線作業を繰り返す作業を行わなければならないため、作業量が多く、試験に時間を要するという問題点がある。   In addition, since the resistance value of the control rod drive coil changes depending on the ambient temperature, when conducting a function confirmation test under high temperature conditions, it is necessary to energize the coil continuously for a long time and raise the temperature to the specified temperature by self-heating. There is a problem that the test takes time and the power consumption during the test is large. In addition, since the simulated load device is expensive, only the minimum required simulated load can be prepared. To confirm the functions of all the current control circuits of the control rod control device, the simulated load is connected and disconnected. Therefore, there is a problem that a large amount of work is required and time is required for the test.

この発明は、上記のような問題点を解消するためになされたもので、汎用的な抵抗器及びリアクトルで模擬負荷装置を構成することにより、入手が容易な汎用品を使用することができ経済的な制御棒制御装置の模擬負荷装置を得ることを目的とする。   The present invention has been made to solve the above-described problems. By configuring the simulated load device with a general-purpose resistor and a reactor, it is possible to use a general-purpose product that is easily available. It is an object to obtain a simulated load device of a typical control rod control device.

この発明に係る制御棒制御装置の模擬負荷装置は、制御棒制御装置の機能および性能を
確認する試験に用いる模擬負荷装置の模擬負荷である制御棒駆動コイルとして、前記制御棒駆動コイルと同等のインダクタンスを有するリアクトルと、前記制御棒駆動コイルと同等の抵抗値を有する抵抗器とを接続して構成したものである。 The simulated load device of the control rod control device according to the present invention is equivalent to the control rod drive coil as a control rod drive coil that is a simulated load of the simulated load device used in a test for confirming the function and performance of the control rod control device. A reactor having an inductance and a resistor having a resistance value equivalent to that of the control rod drive coil are connected to each other.

この発明の制御棒制御装置の模擬負荷装置によれば、模擬負荷である制御棒駆動コイルとして、汎用的な抵抗器及びリアクトルを接続して構成することにより、入手が容易な汎用品を使用することができ経済的な制御棒制御装置の模擬負荷装置を得ることができる。   According to the simulated load device of the control rod control device of the present invention, a general-purpose product that is easily available is used as a control rod drive coil that is a simulated load by connecting a general-purpose resistor and a reactor. Therefore, it is possible to obtain a simulated load device for an economical control rod control device.

In FIG. 1A, 10A to 10C are reactors having the same inductance as the control rod drive coil which is a load of the control rod control device, and 11A to 11C are resistors having the same resistance value as the control rod drive coil. is there. 12A to 12C are ammeter connection terminals for measuring the current flowing through the load, and 13A to 13C are switches for simulating the disconnection of the load. In FIG. 1A, a simulated load of 12 circuits is housed in one housing.

図１（ｂ）では、その１回路の電気回路を示し、リアクトル１０（Ａ,Ｂ,Ｃ）と抵抗器１１（Ａ,Ｂ,Ｃ）と電流計接続用端子１２（Ａ,Ｂ,Ｃ）と開閉器１３（Ａ,Ｂ,Ｃ）が直列に接続されて直列体を構成している。これらの直列体には、制御棒制御装置（図示せず）から電流が供給され制御される。このような電気回路が前記筐体に１２回路収納されている。   FIG. 1B shows an electric circuit of one circuit, which includes a reactor 10 (A, B, C), a resistor 11 (A, B, C), and an ammeter connection terminal 12 (A, B, C). And switches 13 (A, B, C) are connected in series to form a series body. These series bodies are supplied with current from a control rod control device (not shown) and controlled. Twelve circuits of such an electric circuit are accommodated in the housing.

図１に示す模擬負荷装置では、汎用のリアクトル１０（Ａ,Ｂ,Ｃ）と抵抗器１１（Ａ,
Ｂ,Ｃ）を直列に組み合わせることで、制御棒制御装置の負荷である制御棒駆動コイルと
同等のインダクタンス値及び抵抗値を模擬し、制御棒駆動コイルと同等の電流波形を出力することができる。 In the simulated load device shown in FIG. 1, a general-purpose reactor 10 (A, B, C) and a resistor 11 (A,
B, C) can be combined in series to simulate the inductance value and resistance value equivalent to the control rod drive coil that is the load of the control rod control device, and to output a current waveform equivalent to the control rod drive coil. .

そのため、図１に示す模擬負荷装置では、従来、模擬負荷として制御棒駆動コイルを適用していたが、汎用のリアクトル１０（Ａ,Ｂ,Ｃ）及び抵抗器１１（Ａ,Ｂ,Ｃ）の直列体にて模擬することにより、入手が容易な汎用品を使用することができ経済的であり、筐体の小型化が可能となり、稼動中に故障が発生した場合も汎用品を適用しているため、構成品の入手が安易であり、復旧時間を短縮できる。   Therefore, in the simulated load device shown in FIG. 1, conventionally, a control rod drive coil has been applied as a simulated load. However, the general-purpose reactor 10 (A, B, C) and resistor 11 (A, B, C) By simulating in series, it is economical to use general-purpose products that are easily available, and it is possible to reduce the size of the housing, and even if a failure occurs during operation, the general-purpose products can be applied. Therefore, it is easy to obtain the components and the recovery time can be shortened.

These series bodies are supplied with current from a control rod control device (not shown) and controlled. Twelve circuits of such an electric circuit are accommodated in the housing.

図２に示す模擬負荷装置では、実施の形態１の電流計接続端子を電流計２２（Ａ,Ｂ,Ｃ）としたことにより、模擬負荷装置の通電電流を常時監視することができる。模擬負荷装置に直接電流計２２（Ａ,Ｂ,Ｃ）を設置したことにより、各負荷の通電電流を一括して管理できる。また、異常発生時、通電電流を常時監視しているため、故障部位を早急に発見することができる。   In the simulated load device shown in FIG. 2, the ammeter connection terminal of the first embodiment is the ammeter 22 (A, B, C), so that the energization current of the simulated load device can be constantly monitored. Since the ammeter 22 (A, B, C) is directly installed in the simulated load device, the energization current of each load can be managed collectively. In addition, when an abnormality occurs, the energization current is constantly monitored, so that a faulty part can be found quickly.

対応した抵抗値に設定することができ、通電電流値を変化させることができる。可変抵抗器３１（Ａ,Ｂ,Ｃ）を設置したことにより、発熱による抵抗値の変化を補正することができ、正確な通電電流を出力することができる。 In the simulated load device shown in FIG. 3, the variable resistor 31 (A,
Since B, C) is applied, the resistance value can be set to a resistance value corresponding to the temperature of the control rod drive coil by changing the resistance value, and the energization current value can be changed. By installing the variable resistor 31 (A, B, C), a change in resistance value due to heat generation can be corrected, and an accurate energization current can be output.

実施の形態４.
図４は実施の形態４である制御棒制御装置の模擬負荷装置を示す図で、（ａ）はその斜視図で内部に配置された機器を破線で示す。（ｂ）はその電気回路図である。４０Ａ〜４０Ｃは制御棒制御装置の負荷である制御棒駆動コイルと同一のインダクタンスを有するリアクトル、４１Ａ〜４１Ｃは前記制御棒駆動コイルと同一の抵抗値を中心としてその抵抗値を可変できる可変抵抗器、４２Ａ〜４２Ｃは負荷に流れる電流を計測する電流計、４３Ａ〜４３Ｃは負荷の断線模擬をするための開閉器である。図４（ａ）では、３６回路の模擬負荷を収納している。 Embodiment 4.
FIG. 4 is a diagram showing a simulated load device of a control rod control device according to a fourth embodiment, and FIG. 4 (a) is a perspective view showing devices arranged inside by broken lines. (B) is an electric circuit diagram thereof. 40A to 40C are reactors having the same inductance as the control rod drive coil that is the load of the control rod control device, and 41A to 41C are variable resistors whose resistance values can be varied around the same resistance value as the control rod drive coil. 42A to 42C are ammeters for measuring the current flowing through the load, and 43A to 43C are switches for simulating the disconnection of the load. In FIG. 4A, 36 simulated loads are accommodated.

図４に示す模擬負荷装置では、制御棒制御装置１面に収納されている最大負荷回路と同一の数量の模擬負荷回路（リアクトル４０Ａ〜４０Ｃ、可変抵抗器４１Ａ〜４１Ｃ）を収納しているため、実機の制御棒駆動コイル接続条件と同一の条件（模擬負荷装置の同時接続数が制御棒駆動コイルと同数）にて試験を行うことができる。制御棒制御装置の模擬負荷装置を汎用の抵抗４１Ａ〜４１Ｃとリアクトル４０Ａ〜４０Ｃで構築することから、装置のコストが低減できる。装置のコストが低減されることから、プラント個別に模擬負荷装置を保有することが可能となり、プラント間を移動させることが不要となる。   In the simulated load device shown in FIG. 4, the same number of simulated load circuits (reactors 40A to 40C, variable resistors 41A to 41C) as the maximum load circuit stored on the surface of the control rod control device 1 are stored. The test can be performed under the same conditions as the actual control rod drive coil connection conditions (the number of simultaneous connections of the simulated load device is the same as the number of control rod drive coils). Since the simulated load device of the control rod control device is constructed with general-purpose resistors 41A to 41C and reactors 40A to 40C, the cost of the device can be reduced. Since the cost of the apparatus is reduced, it is possible to own a simulated load apparatus for each plant, and it becomes unnecessary to move between plants.

また、模擬負荷回路個別に電流計を設置した構成としたことにより、電流計の接続、取り外し作業を行うことが不要となる。
また、抵抗器を可変抵抗器としたことから、制御棒駆動コイルの温度条件によって異なる抵抗値を自由に設定し模擬できることから、試験時間を短縮することができる。
また、制御棒制御装置１面分の負荷に対応した回路を収納していることから、試験時の模擬負荷の接続、解線作業が低減でき、試験時間の短縮とそれに伴う作業ミスの防止に寄与することができる。
さらに、模擬負荷装置の同時接続数は実機と同一となるため、模擬負荷結果を置換判断することなく実機と同レベルの判断となり、模擬負荷装置の性能が著しく向上することができる。 In addition, since the ammeter is installed in each simulated load circuit, it is not necessary to connect and remove the ammeter.
Further, since the resistor is a variable resistor, different resistance values can be freely set and simulated depending on the temperature condition of the control rod drive coil, so that the test time can be shortened.
In addition, because the circuit corresponding to the load for one control rod control device is housed, it is possible to reduce the connection of the simulated load and the disconnection work at the time of the test, to shorten the test time and to prevent the work mistake accompanying it. Can contribute.
Furthermore, since the number of simultaneous connections of the simulated load device is the same as that of the actual device, the determination of the same level as that of the actual device is made without replacing the simulated load result, and the performance of the simulated load device can be significantly improved.
