Description
特に、複数の負荷試験装置1を設置して行われる空調設備の負荷試験で有効である。
第1実施形態(コンピューターサーバーを冷却する空調設備の負荷試験である第1負荷試験、図1~図6参照)では、x方向とy方向が水平方向で、z方向が鉛直方向となる。
第2実施形態(発電機やバッテリーの負荷試験である第2負荷試験、図1~図3、図7~図9参照)では、x方向とz方向が水平方向で、y方向が鉛直方向となる。
第1実施形態では、下面10dが底面となり、第2実施形態では、前面10eが底面となる。
筐体10の第1領域11における第1側面10aや第2側面10bには、第1端子接続部41、第2端子接続部42、リレー部45が設けられる。
特に、第1端子接続部41と第2端子接続部42は、後述するラック取り付け金具51が取り付けられる位置よりも前面10eに近い側に設けられる。
操作部47は、筐体10の前面10e、若しくは、筐体10の第1領域11における上面10cに着脱可能な状態で取り付けられる。
カバー13は、鉄やアルミニウムなどの導電性材料で構成される。
吸気を効率良く行うために、第1側面10aや第2側面10bについても、第1端子接続部41などの部材が取り付けられた領域以外に開口する領域が設けられるのが望ましい。
当該サーバーラック90は、通常はコンピューターサーバーを保持するものであり、第1負荷試験の際には、当該コンピューターサーバーに代えて、負荷試験装置1を保持する。
特に、サーバーラック90が19インチラックの場合には、筐体10の第1側面10aに取り付けたラック取り付け金具51と、筐体10の第2側面10bに取り付けたラック取り付け金具51の幅(サーバーラック90に取り付ける穴と穴の距離)が19インチ(約480mm)となるように、筐体10の幅などが設定される。
コンピューターサーバーを冷却する空調設備の第1負荷試験(第1実施形態)では、第1端子接続部41は、当該コンピューターサーバーに電力供給するものと同じ商用電源と接続され、抵抗器Reは当該商用電源からの電力供給を受ける。
発電機やバッテリーの第2負荷試験(第2実施形態)では、第1端子接続部41は、試験対象電源(発電機やバッテリー)と接続され、抵抗器Reは当該試験対象電源からの電力供給を受ける。
ただし、図6における第1端子接続部41と商用電源を接続するケーブルや第2端子接続部42と商用電源を接続するケーブル、図8における第1端子接続部41と試験対象電源を接続するケーブルや第2端子接続部42と商用電源を接続するケーブルを除き、当該短絡バーや当該ケーブルの図示は省略している。
当該冷却ファンは、商用電源(負荷試験装置駆動用電源)で駆動される(図2参照)。
この場合には、冷却部30の冷却ファンや、操作部47を負荷試験装置1の筐体10などと別体で持ち運びすることが可能になり、負荷試験を行う現地で冷却部30や操作部47を筐体10などに取り付けることが可能になる。
特に、操作部47を筐体10から外した状態(少なくとも、操作部47を筐体10の上面10cや下面10dから外した状態)で、冷却部30の冷却ファンの着脱が容易に行える。
冷却部30から抵抗部20に送り込まれた冷却風の排気は、筐体10の後面10fから行われる。
第1端子接続部41とリレー部45との間、若しくは第1端子接続部41には、VCB(Vacuum Circuit Breaker)などの遮断器が設けられるのが望ましい。
ただし、第2負荷試験においては、第2端子接続部42も試験対象電源と接続され、試験対象電源から供給される電力で、冷却部30の冷却ファンやリレー部45のリレーや操作部47が駆動される形態であってもよい。
第2端子接続部42とリレー部45との間、若しくは第2端子接続部42には、MCCBVCB(Molded Case Circuit Breaker)などの遮断器が設けられるのが望ましい。
リレー部45を構成するリレー(冷却ファンリレーRC、第1リレーR1~第8リレーR8)は、商用電源(負荷試験装置駆動用電源)で駆動される(図2、図3参照)。
電源スイッチ47aがオン状態にされると、第1端子接続部41の遮断器若しくは不図示のリレーがオン状態にされて、リレー部45の第1リレーR1~第8リレーR8に、第1端子接続部41を介して負荷試験装置1に接続された商用電源(第1実施形態)若しくは試験対象電源(第2実施形態)からの電流が流れうる状態にされる。
また、電源スイッチ47aがオン状態にされると、第2端子接続部42の遮断器若しくは不図示のリレーがオン状態にされて、リレー部45の冷却ファンリレーRCや操作部47に、第2端子接続部42を介して負荷試験装置1に接続された商用電源からの電流が流れうる状態にされる。
冷却ファンスイッチ47bがオン状態にされると、冷却ファンリレーRCがオン状態にされて、冷却部30の冷却ファンに、第2端子接続部42を介して負荷試験装置1に接続された商用電源からの電流が流れうる状態にされる。
第1抵抗切替スイッチ47c1がオン状態にされると、第1抵抗器群G1のリレー(第1リレーR1)がオン状態にされて、第1抵抗器群G1に、第1端子接続部41を介して負荷試験装置1に接続された商用電源(第1実施形態)若しくは試験対象電源(第2実施形態)からの電流が流れうる状態にされる。
第2抵抗切替スイッチ47c2~第8抵抗切替スイッチ47c8も、同様で、オン状態にされると、対応する抵抗器群のリレーがオン状態にされて、当該抵抗器群に、第1端子接続部41を介して負荷試験装置1に接続された商用電源(第1実施形態)若しくは試験対象電源(第2実施形態)からの電流が流れうる状態にされる。
表示部47dは、さらに、第1抵抗器群G1~第8抵抗器群G8に流れる電流、第1抵抗器群G1~第8抵抗器群G8に印加された電圧、電力値、負荷量、試験時間などの数値や、正常に動作しているか否かなどの運転状態などを表示する形態であってもよい。
操作部47の筐体10への取り付けは、筐体471に設けられた第1取り付け穴49aを介したネジ止め等により行われる。
操作部47が前面10eに取り付けられた場合には、第1領域11の上面10cの開口と下面10dと側面(第1側面10a、第2側面10b)の開口の少なくとも一つを使って冷却風の吸気が行われる(第2実施形態)。
このため、抵抗部20と冷却部30を水平方向に配置されるように負荷試験装置1が設置されても、上下方向に配置されるように負荷試験装置1が設置されても、操作を容易に行うことが可能になる。
凹部473の裏側(電源スイッチ47aなどが設けられた表側と逆側)には、コネクタ48が設けられ、電源スイッチ47aと第1端子接続部41や第2端子接続部42、冷却ファンスイッチ47bと冷却ファンリレーRC、第1抵抗切替スイッチ47c1と第1リレーR1などの電気的な接続は、当該コネクタ48を介して行われる。
コネクタ48を介した着脱により、容易に操作部47の電気配線が可能になる。
操作部47が筐体10の前面10eに取り付けられる第1実施形態では、第2取り付け穴49bを介して、取っ手53が前面10eに取り付けられ、負荷試験装置1のサーバーラック90への着脱に使用される。
操作部47が筐体10の第1領域11における上面10cに取り付けられる第2実施形態では、第2取り付け穴49bを介さずに、取っ手53が前面10eに取り付けられ、吸気目的で、底面となる筐体10の前面10eと、負荷試験装置1を設置する設置面の間に一定の間隔を設けるために使用される。
空調設備は、コンピューターサーバーなどの冷却対象物の位置を考慮して吹き出し方向などが設定されているため、コンピューターサーバーが設置された位置で、且つ当該コンピューターサーバーが発する発熱量と同等の発熱を行う負荷試験装置1を用いることで、実際のコンピューターサーバーを動作させている環境に近い状態で空調装置の負荷試験(第1負荷試験)を行うことが可能になる。
このとき、取っ手53若しくはキャスター54によって、筐体10の底面を構成する前面10eと負荷試験装置1の設置面との間から冷却風を取り入れる隙間を設けることが可能になる。
この場合、負荷試験装置1は、制御部58と通信部59を更に備える。
CPUなどの制御部58は、操作部47及び通信部59を制御する。
通信部59は、通信端末69から、操作部47のスイッチに対応するリレーを動作させる指示に関する信号を受信し、通信端末69に負荷試験装置1の状態(リレーのオンオフ状態など)に関する情報を送信する。
通信端末69が、複数の負荷試験装置1と通信し、当該複数の負荷試験装置1の操作部47を動作させることで、同時に複数の負荷試験装置1の状態を1台の通信端末69上で表示させ、且つ複数の負荷試験装置1を一人の作業者で操作することが可能になる。
特に、複数の負荷試験装置1を設置して行われる空調設備の負荷試験(第1負荷試験)で有効である。
冷却状態表示領域77bが操作されると、対応する負荷試験装置1の冷却ファンリレーRC(冷却ファンスイッチ47b)のオンオフ状態の切替が行われる。
第1表示領域77c1が操作されると、対応する負荷試験装置1の第1リレーR1(第1抵抗切替スイッチ47c1)のオンオフ状態の切替が行われる。
第2表示領域77c2~第8表示領域77c8も、同様で、操作されると、対応する負荷試験装置の第2リレーR2~第8リレーR8(第2抵抗切替スイッチ47c2~第8抵抗切替スイッチ47c8)のオンオフ状態の切替が行われる。
第1切替ボタン領域77eが操作されると、通信端末69と通信している他の負荷試験装置1のオンオフ状態表示パターンD1の表示への切替が行われる。
第2切替ボタン領域77fが操作されると、通信端末69と通信した負荷試験装置1の負荷試験情報の一覧表示(履歴表示パターンD2)の表示への切替が行われる。
例えば、抵抗値が小さい抵抗器群の1つに対応するリレーだけをオン状態にし、他の抵抗器群に対応するリレーをオフ状態にする形態が考えられる。
また、急激な負荷の変動による動作不良を避けるため、オン状態にされているリレーの総てを同時にオフ状態にするのではなく、段階的に、すなわち、第1時間t1(例えば、t1=10秒)の間隔を空けて、1つずつオフ状態にしていくのが望ましい。
これにより、オン状態にされているリレーに対応する抵抗器群にだけ、商用電源または試験対象電源から第1端子接続部41を介して電力供給が行われる。
ただし、抵抗器群に対応するリレーのうち少なくとも1つは、負荷を少なくする制御を開始してから第2時間t2(例えば、t2=5分)が経過するまではオフ状態にせずオン状態を維持させる。
警告表示パターンD3は、「通信部との通信が切断されたこと」、及び「負荷試験装置の負荷を段階的に下げ、第2時間t2の経過後に運転を停止させること」を示す文字を出力する。
なお、警告表示パターンD3に代えて、若しくは加えて、通信端末69が、「通信部との通信が切断されたこと」、及び「負荷試験装置の負荷を段階的に下げ、第2時間t2の経過後に運転を停止させること」を示す音声を出力する形態であってもよい。
その後に、制御部58は、冷却ファンリレーRCをオフ状態にして、負荷試験を終了する。
なお、通信回復表示パターンD4に代えて、若しくは加えて、通信端末69が、「通信部との通信が回復したこと」、「負荷試験の継続が可能であること」、「(段階的なオフ制御によりスイッチのオンオフ状態が変化しているので)スイッチのオンオフ状態を確認すること」を示す音声を出力する形態であってもよい。
また、負荷を下げてから第2時間t2が経過するまでは、低負荷で負荷試験が続けてられており、作業者による操作部47の操作、若しくは通信状態回復後の作業者による通信端末69の操作によって、負荷を上げて、高負荷の負荷試験を再開させることも出来る。
制御部58は、ステップS11で、通信部59と通信端末69との間の通信状態が第4時間t4以上(例えば、t4=10秒)継続して、切断されたか否かを判断する。
切断されている場合には、ステップS12に進められ、切断されていない場合には、第5時間t5(例えば、t5=5秒)後に、再びステップS11の判断を行う。
具体的には、制御部58は、抵抗器群に対応するリレーであって、オン状態にされているものの1つをオフ状態にする。
ただし、抵抗器群に対応するリレーであって、オン状態にされているものが所定の数(例えば、1つ)になった場合には、当該リレーをオフ状態にはせずに、ステップS13に進められる。
また、通信端末69は、通信部59と通信端末との間の通信状態が第4時間t4以上継続して、切断された場合に、警告表示パターンD3を表示する。
経過した場合は、ステップS16に進められ、経過していない場合は、ステップS14に進められる。
制御部58は、ステップS14で、通信部59と通信端末69との間の通信状態が回復したか否か、すなわち、通信部59と通信端末69との間の通信が可能な状態になったか否かを判断する。
通信状態が回復した場合には、ステップS15に進められ、回復していない場合には、ステップS12に進められる。
