Technical Field

The invention relates to the technical field of on-load tap changers, in particular to a gear system for changing forward and reverse rotation into one-way rotation and eliminating accumulated errors.

Background

In the existing on-load tap-changer, because the structural requirements are basically positive and reverse switching, sufficient arc quenching time can be ensured between each contact system of the change-over switch in both positive and reverse switching directions; when the switching capacity is small and the number of required transition contacts is small, the arc quenching time can be met; when the switching capacity is large and the number of required transition contacts is large, the arc quenching time is difficult to meet, even if the switching capacity is not large enough, once the mechanical dimension error is overlarge, the arc quenching time among contact systems cannot meet the requirement, the short circuit of the tap switch can be possibly caused, the tap switch is burnt once the short circuit occurs, the transformer is damaged when the burning condition of the tap switch is slight, and the transformer is burnt and seriously damaged when the burning condition of the transformer is serious. If the transmission of the change-over switch is changed into unidirectional transmission, the problem can be well solved only by ensuring the arc extinguishing time among the contact systems in one direction.

The existing one-way transmission is mostly belt transmission or chain transmission and is not suitable for an on-load tap-changer, certain errors can exist in every transmission of motor transmission, and due to the fact that the one-way transmission is adopted, the errors cannot be eliminated, and the errors can be accumulated to be larger along with the increase of the transmission times. If the unidirectional transmission mode is applied to the on-load tap-changer, the electric mechanism used by the on-load tap-changer can be applied to the on-load tap-changer only by eliminating the error transmitted by the electric mechanism because the transmission torque of the electric mechanism is 33 +/-0.5 circles and the error range is very large.

As shown in fig. 5: the groove poking piece 1 rotates anticlockwise, the groove poking piece 1 drives the first shaft rod to rotate together, the first shaft rod pokes the grooved pulley 6, and the grooved pulley 6 rotates clockwise; the grooved wheel 6 drives the first gear 7 and the second gear 10 to rotate clockwise together; the first gear 7 transmits the torque to the second one-way gear 19, the second one-way gear 19 rotates anticlockwise, the inner hole inclined plane of the second one-way gear 19 applies pressure to the second shaft rod 27, the second shaft rod 27 rotates around the third shaft rod 29, the second one-way gear 19 does not drive the second shaft rod 27 to rotate together, the torque of the set of gears is not transmitted to the output shaft 13, and the set of gears idles. As shown in fig. 6: the other group of gears 10 transmits the torque to the gear five 32, the gear five 32 transmits the torque to the one-way gear 16, the one-way gear 16 rotates clockwise, the one-way gear 16 drives the shaft rod four 30 to rotate clockwise together, the shaft rod four 30 drives the output shaft 13 to rotate clockwise together through the shaft rod three 29, the output shaft 13 transmits the torque to the gear four 25, the gear four 25 transmits the torque to the gear three 23, and the gear three 23 transmits the torque to the energy storage system 18.

The scope of the present invention is not limited to the technical solutions disclosed in the embodiments, and any modifications, equivalent substitutions, improvements, etc. made to the above embodiments according to the technical spirit of the present invention fall within the scope of the present invention.
