Abstract
Description
(実施の形態1の構成)
図1は、本発明の実施の形態1における電力変換装置における機能モジュールの配置構成の一例を示す図であり、図2は、本発明の実施の形態1における電力変換装置の機能構成の一例を示す図である。図1及び図2に示すように、電力変換装置2は、冷却ファンユニット21、コンデンサユニット4、電力変換器5を備えている。冷却ファンユニット21は、複数の冷却ファン23を備えている。電力変換器5は、収容部50に収容されており、収容部50に密閉室8及び開放室9が収容されている。密閉室8は、外部から密閉された空間である。開放室9は、外気と通ずる開口を備える空間である。開放室9には、冷却器6が配置される。密閉室8には、電力変換器5が配置されており、防塵、防水、特に鉄道車両のため鉄粉等が機能モジュールに混入して劣化することを防止する。
(実施の形態2の構成)
実施の形態2では、冷却器6の詳細構成について説明する。図12は、本発明の実施の形態2における機能モジュール7_2、7_3と冷却器6との位置関係の一例を示す図である。なお、図12の電力変換器5は、機能モジュール7_2及び機能モジュール7_3の組み合わせからなっている。図12に示すように、冷却器6は、例えばヒートシンクであって、放熱部41と、受熱部43とを備えている。受熱部43は、平面を有する部材で形成され、上記で説明した機能モジュール7_2、7_3のそれぞれが、受熱部43に接して設けられることで、機能モジュール7_2、7_3のそれぞれに設けられている電力変換ユニットで発生した熱が受熱部43を介して放熱部41に伝達される。放熱部41は、複数の放熱フィン45を備えている。放熱フィン45は、冷却ファン23の風向きと同一方向の風向きに形成されている。放熱部41は、受熱部43を介して伝達された熱を放熱フィン45から放熱する。
以上の説明から、電力変換装置2は、受熱部43を密閉室8と接する位置に設け、放熱部41を外気と通ずる開放室9に設ける。よって、電力変換装置2は、電力変換ユニット等の電気部品及び図示しない充電部に外気を直接当てさせない。この結果、電力変換装置2は、電力変換ユニット等の電気部品の信頼性を確保させることができる。
(実施の形態3の構成)
実施の形態3では、電力変換装置2が鉄道車両51に設けられた一例を説明する。図13は、本発明の実施の形態4における電力変換装置2が搭載される鉄道車両51の一例を示す図である。図13に示すように、鉄道車両51は、パンタグラフ71、トランス72、補助電源装置73、空調ユニット74等を備えている。なお、空調ユニット74には、例えば、電源線76を介して補助電源装置73から電力が供給されてもよい。
以上の説明から、電力変換装置2は、異なる負荷ごとに異なる周波数の交流電力を供給する。よって、例えば、複数台の圧縮機92、室外送風機93、及び複数台の室内送風機94等を駆動させる電源としての電力変換装置2の構造部品が共有化される。したがって、鉄道車両51に搭載される空気調和機81を構成する機器の配置制約が緩和される。
