An on-load tap changer is for uninterrupted diverter switch operation. The on-load tap changer includes: a first module having a first module shaft; and a second module having a second module shaft. The first module shaft is configured to actuate the first module. The second module shaft is configured to actuate the second module. The first module shaft and the second module shaft are mechanically coupled to one another in such a way that the first module shaft is configured to drive the second module shaft and the second module is configured to be actuated with a time delay with respect to the first module.

An on-load tap changer uninterruptedly switches between winding taps of a tap-changing transformer. The on-load tap changer includes: at least one selector configured to preselect, in a powerless manner, a selected winding tap of the winding taps; at least one diverter switch configured to actually switch loads from a previous winding tap to a preselected winding tap of the winding taps; at least one toothed gearing comprising a first gearwheel and a second gearwheel, the first gearwheel being assigned to the selector, and the second gearwheel being assigned to the diverter switch; and a drive shaft, which is configured to be actuated by a motor drive. The first gearwheel and the second gearwheel are directly interconnected mechanically in such a way that the first gearwheel and the second gearwheel are simultaneously actuatable. The drive shaft is configured to drive either the first gearwheel or the second gearwheel.

Implementations of the subject matter described herein provide a switching apparatus. The switching apparatus includes: a switching component including a first main shaft, which is adapted to selectively connect and disconnect at least one circuit in response to the rotation of the first main shaft; and an operating mechanism including a second main shaft for actuating the first main shaft to rotate via the second main shaft; wherein the switching component further includes a first interface, and the operating mechanism further includes a second interface, and the second main shaft to be detachably coupled to the first main shaft in response to the engagement of the first interface and the second interface.

A electrical pole unit includes an actuator shaft that is rotatable about a switch axis to switch the pole unit between open and closed conditions. The actuator shaft is configured to mate coaxially with another actuator shaft in another pole unit to transmit rotation from one actuator shaft to another without a fastener to interconnect the shafts.

A trip cam assembly is for a multi-pole electrical switching apparatus. The trip cam assembly includes a first trip cam, a second trip cam, and an interconnect member coupled to the first trip cam and the second trip cam.

A bearing assembly includes an inner race, an outer race, a cage, and a plurality of balls. The inner race is configured to be coupled to a shaft. The cage includes a body having a plurality of projections and a plurality of openings. The cage is positioned between the inner race and the outer race, and is constructed from a corrosion-resistant and gall-resistant material. Each of the plurality of balls is received in an associated one of the plurality of openings, and the plurality of balls is positioned between the inner race and the outer race.
