The hinged structure has the beneficial effects of being convenient to disassemble, wide in rotating range, low in cost and the like.

The invention provides a spring energy storage device for an on-load tap-changer, and relates to a spring energy storage device. The spring energy storage device aims to solve the problems that according to an existing over-dead-point type spring energy storage device, the rotation angle range of tension spring drive components is small, and therefore the reliability of the spring energy storage device is low. A second transmission shaft is installed on the lower portion of a side plate through a first bearing block. The second transmission shaft and a third transmission shaft are coaxially arranged. A transmission gear is installed on the second transmission shaft and located between the side plate and a switching support plate. The end face, facing a transmission shifting block, of the transmission gear is provided with a first shifting column and a second shifting column. The first shifting column and the second shifting column are integrated with the transmission gear. The second transmission shaft is fixedly sleeved with one end of a switching shifting block. A transmission column is horizontally and fixedly installed to the other end of the switching shifting block. The transmission column is sleeved with a transmission shaft sleeve and a rotating sleeve in sequence. One end of a tension spring is installed on the transmission shaft sleeve, and the other end of the tension spring is fixed through a fixing column. Two limiting shaft sleeves are located on the periphery of a limiting wheel. The spring energy storage device is used for the on-load tap-changer.
