To provide a track relay test device which can test whether a track relay normally works or breaks down even in a general office or the like.SOLUTION: A track relay test device is composed of: a high-voltage line pair which is an electrical path of high-voltage AC power; a low-voltage line pair which is an electrical path of low-voltage AC power in which the high-voltage AC power of the high-voltage line pair is stepped down and a phase is shifted by a phase adjustment circuit; a changeover switch which selects whether the low-voltage AC power of the low-voltage line pair is supplied to a low-voltage terminal pair of the track relay in a first phase or is supplied in a second phase that is inverted from the first phase, or is not supplied; a track relay connection connector which supplies the high-voltage AC power of the high-voltage line pair to the track relay and supplies the output from the changeover switch to the track relay; and a light emission display part which is electrically connected to an output terminal of the track relay and emits light according to a contact point state of the track relay.SELECTED DRAWING: Figure 1
【課題】一般的な事務所等でも軌道リレーが、正常に動作するか、故障しているかを試験することが可能な軌道リレー試験装置を提供する。【解決手段】本発明に係る軌道リレー試験装置は、高圧交流電力の電路である高圧ライン対と、高圧ライン対の高圧交流電力が降圧され、位相調整回路によって位相がずらされた低圧交流電力の電路である低圧ライン対と、低圧ライン対の低圧交流電力を第1の位相で軌道リレーの低圧端子対に供給するか、又は第1の位相と反転した第2の位相で供給するか、又は供給しないか、を選択する切り替えスイッチと、高圧ライン対の高圧交流電力を軌道リレーに供給すると共に、切り替えスイッチからの出力を軌道リレーに供給する軌道リレー接続用コネクタと、軌道リレーの出力端子と電気接続し、軌道リレーの接点状況に応じて発光を行う発光表示部と、からなることを特徴とする。【選択図】図1
