Description
図1は、この発明の実施の形態1によるサイリスタ起動装置の構成を示す回路ブロック図である。図1を参照して、この発明の実施の形態1によるサイリスタ起動装置100は、停止している同期機20を所定の回転速度まで加速させることにより、同期機20を起動させる。
図2は、サイリスタ起動装置100の動作を示すタイムチャートである。図2には、コンバータ1から出力される直流電流Idおよび同期機20の回転速度が示されている。
上述した実施の形態1によるサイリスタ起動装置100によれば、第1の同期機を起動させる場合には、第2の同期機を起動させる場合に比べて切り替え回転速度が高いため、断続転流モードに費やされる時間が長くなる。そのため、同期機20の昇速率(回転速度が上昇する比率)が低下し、結果的に同期機20の起動に時間がかかってしまう場合が起こり得る。
サイリスタ起動装置100によって同期機20の電機子巻線ATU,ATV,ATWを通電した場合、電機子巻線ATU,ATV,ATWには熱損失(ジュール熱)が発生する。熱損失は電流の大きさの二乗に比例する。熱損失によって同期機20が過熱されるのを防ぐため、同期機20には冷却構造が設けられているものがある。
