Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the present embodiment provides an operating mechanism for a non-excited tap changer, which includes a rotating shaft 5, a positioning handle 2 sleeved on the rotating shaft and capable of sliding axially relative to the rotating shaft, and a protective cover 3 connected to the positioning handle 2, wherein the rotating shaft 5 is connected to a moving contact system so as to transmit power to the moving contact system, a washer 4 is disposed at an upper end of the rotating shaft, and a positioning spring 6 is disposed between the washer 4 and the positioning handle 2. The protective cover 3 mainly plays a role in protecting the gasket 4, the rotating shaft 5 and the positioning spring 6 inside the positioning handle. The lower end of the positioning handle 2 is configured with the positioning disk 1, and the positioning disk 1 fixes the switch body 9 on the box cover 8 through the fixing nut 7. The gear shifting device is characterized in that a mutually matched positioning gear shifting mechanism is arranged between the positioning handle 2 and the positioning plate 1, the positioning gear shifting mechanism comprises a limiting guide groove 10 arranged on the positioning handle or the positioning plate, a plurality of positioning grooves 11 are arranged in the limiting guide groove 10, positioning teeth 12 are arranged on the positioning plate 2 or the positioning handle 1, and the positioning teeth 12 are movably arranged in the limiting guide groove and are configured with the positioning grooves to realize gear shifting of a switch. The limiting guide groove 10 can be arranged on the positioning handle or on the positioning plate, and correspondingly, the positioning teeth can be arranged on the positioning plate or the positioning handle. In the present embodiment, the example in which the position-limiting guide groove 10 is provided on the positioning plate 2 and the positioning tooth 12 is provided on the positioning handle 1 will be described. The positioning handle penetrates through the rotating shaft and is meshed with the positioning disc through the male and female positioning teeth, the positioning spring 6 is propped between the positioning handle and the gasket, and the gasket 4 is fixed on the rotating shaft to limit the axial movement of the positioning spring.
As shown in fig. 2, the limiting guide groove 10 is an arc-shaped limiting guide groove, two arc-shaped limiting guide grooves are circumferentially distributed on the positioning plate 2, a plurality of positioning grooves 11 are circumferentially arranged in the limiting guide groove at intervals, wherein the number of the positioning grooves 11 in each arc-shaped limiting guide groove 10 is matched with the number of the gears of the off-circuit tap changer.
