計時開閉装置において、動作時刻を設定する操作
中には開閉器の動作を禁止する禁止回路に対し、
別の計時回路を付加することにより、時刻設定動
作の完了後に開閉器の動作禁止を解除する手動操
作スイツチを操作しない場合でも、一定時間後に
自動的に開閉器の動作禁止状態を解除する機能を
備えた計時開閉装置。 In a timing switchgear that operates a switch at a preset time, there is a prohibition circuit that prohibits the switch from operating during the operation to set the operating time.
By adding a separate timing circuit, we have added a function that automatically cancels the switch's prohibition state after a certain period of time, even if the manual operation switch that cancels the prohibition of the switch after the time setting operation is completed is not operated. Equipped with a timing switchgear.
