Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further detailed.
See accompanying drawing 1 and accompanying drawing 2, the present embodiment is arranged on load ratio bridging switch mechanism case tank wall by holder 10.
Described loaded switch remote operation controller comprises motor 6, the reductor 5 be connected with motor 6, the connecting rod 8 be flexibly connected with reductor 5 by web joint 7 and the holder 10 slided on connecting rod 8; The transmission shaft 4 of described reductor 5 is with the driver slot docking on the hand handle hole on on-load tap changers of transformers mechanism case.Described connecting rod 8 is hinged with web joint 7, and described holder 10 is sheathed on connecting rod 8 by embracing a ring 9, described holder 10 by the journal stirrup 3 that arranges with embrace a ring 9 and be connected, be provided with coupling bolt between described journal stirrup 3 and armful ring 9.The side that described holder 10 is connected with load ratio bridging switch mechanism case tank wall is U-shaped connection pawl 2, and described U-shaped connection pawl 2 is provided with fastening bolt 1.By regulating the position of the position of holder 10 and the adjustable in length transmission shaft 4 of connecting rod 8, to adapt to the mechanism case size of different model.
The utility model adopts mechanical hook-up to drive, and do not change mechanism case structure, reconfiguration secondary circuit, does not change measuring principle, does not affect the accuracy of test data.Loaded switch remote operation controller is driven by the transmission shaft 4 pairs of loaded switch mechanism cases of self, be not subject to the restriction of loaded switch mechanism case field power supply condition and control loop, eradicated when transformer has a power failure test, loaded switch cannot electrically operatedly bother.Adopt the utility model in direct current resistance test process, can at the tap position of the long-range adjustment on-load tap changers of transformers of instrument side.
