Abstract (en)
[origin: WO2017207237A1] An on-load tap changer head (20) for an on-load tap changer (10) comprises a first region (21) which is formed in the on-load tap changer head (20) and through which an insulating fluid (17) of the on-load tap changer (10) can flow; a second region (23) which is separated from the first region (21) by a wall (22); a detector apparatus (39) for detecting an elevated flow rate of the insulating fluid (17), comprising a flow control flap (24) which is arranged in the first region (21) and switches from a first position (24A) to a second position (24B) starting from a defined flow rate of the insulating fluid (17); a first coupling magnet (25) which is fastened to the flap (24) and is located in the immediate vicinity of the wall (22) in the second position (24B) of the flow control flap (24); a second coupling magnet (26) which is arranged in the immediate vicinity of the wall (22) in the second region (23); a switch (27) which is arranged in the second region (23) and is coupled to the second coupling magnet (26) in such a way that the process of switching over the flow control flap (24) from the first position (24A) to the second position (24B) operates the switch (27).
