To provide a power supply changeover notification device for a traffic signal system, capable of facilitating visual confirmation, from an outside, concerning a fact that power supply is changed over to the power supply from a power storage part of an uninterruptible power supply apparatus.SOLUTION: A power supply changeover notification device includes: a main body part 2 connected to a traffic light 16 at an intersection so as to control lighting of a traffic signal; heat shielding plates 3 arranged to cover the main body part 2; and a notification part 4 attached to the heat shieling plate. The device is fixed to a utility pole via fixing parts attached to the other heat shielding plate 3. When power supply from an external commercial power source is interrupted, power supply is changed over from an AC input line 11 side to a power storage part 12e side by a control switch 12a, and an interlocking switch 17 is turned on. When the interlocking switch 17 is turned on, a light emission part 4a of the notification part 4 starts lighting by power from the power storage part 12e.SELECTED DRAWING: Figure 5
【課題】無停電電源装置の蓄電部からの電力供給に切換わったことを外部から容易に目視で確認できる交通信号システム用電源切換報知装置を提供する。【解決手段】交差点の交通信号灯器16と接続し、信号点灯制御を行う本体部2と、本体部2を覆うように配置した遮熱板3と、遮熱板に取り付けられた報知部4とから構成され、他の遮熱板3に取り付けた固定部を介して、電柱に固定されている。外部の商用電源からの電力供給が途絶えると、制御スイッチ12aにより電力供給がAC入力線11側から蓄電部12e側に切換わり、連動スイッチ17がオン状態となる。報知部4の発光部4aは、連動スイッチ17がオン状態になることで、蓄電部12eからの電力で点灯を開始する。【選択図】図5
