Abstract
PURPOSE: To provide an electric contrller for a tap changer which has a simple construction and high reliability by employing electric relays.
CONSTITUTION: When a power switch SW is closed, a time limit relay TL is energized, and its contact TL1 is thereby opened and its contact TL2 is closed. When "high" side push-button switch 7R is depressed, the operation coil m of a keep relay RX is energized to energize a "high" side control relay RC and to accordingly close its contact RC1. When a motor M is started, a limit switch b4 is opened to deenergize a time limit relay TL. When a tap is changed, the limit switch b4 is closed to energize the return coil l of the keep relay RX is energized. Thus, the "high" side control relay RC is deenergized to open the contact RC1 so as to stop a motor M. After the lapse of predetermined time, the relay TL is operated to return to normal state.
