Abstract
PURPOSE:To disconnect and hang an on-load tap changing transformer by providing a normally open contact between one tap selector and the end of a line, providing a normally closed contact synchronized with the contact at the other tap selector, and providing a line end connection switch which can switch the two types of contacts only when one tap selector is energized. CONSTITUTION:Insert contactors 13A, 13B, stationary contactors 6A, 6B and stationary contactors 6A', 6B' in which current limiting resistors 8A, 8B are connected in series are inserted between tap selectors 4A, 4B and a line end 11. A movable contactor 7 is selectively brought into contact with the contactors 6A, 6A', 6B, 6B', and a movable contactor 10 is selectively connected to the stationary contactors P and (n) of a pole changer 9. Further, a normally open contact 15A is provided between the one tap selector 4B and the line end 11, a normally closed contact 15B is provided between the other selector 4A and the contactor 13B of a changeover switch 5, and two types of the contacts 15A, 15B are driven synchronously by a line end connection switch 14. Symbol 21A denotes a central winding tap led from the end of a main winding 1. The end 11 is led to a load in a single phase circuit, and led to a neutral point in a 3-phase circuit.
