Abstract

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.

Description

technical field [0001] The invention relates to a spring energy storage device of an on-load tap changer. Background technique [0002] At present, the quick mechanism of the on-load tap-changer is driven by a spring energy storage device, and the most common one is the over-dead point type spring energy storage device. The rotation angle range of the tension spring driving part of the over-dead-point spring energy storage device is small, and the maximum angle is only 90 degrees. [0003] The action time of the fast mechanism of the on-load tap-changer has strict requirements. The action cannot be too fast. Too fast action time directly affects the reliability of the product. The size of the tension spring determines the length of the action time, so the design of the tension spring tension It should not be too large, that is, the surplus coefficient of the tension spring force is relatively small. When the lubrication of the quick mechanism of the on-load tap-changer, th...
