The purpose of this utility model is to provide a kind of outdoor high-voltage alternating current isolating switch, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of outdoor high-voltage alternating current isolating switch, including upper bed-plate and lower bottom base, the first insulation column, the second insulation column, movable touch knife and static contact it is provided with on described upper bed-plate, described static contact is fixed on the first insulation column top, described movable touch knife includes connecting lever and is arranged on the moving contact of connecting lever one end, and the other end of described connecting lever and the top of the second insulation column are rotationally connected by hinge；Telescopic insulating post it is movably hinged with on the downside of the left end of described connecting lever, the lower end of described telescopic insulating post is connected through upper bed-plate with the sleeve being positioned on lower bottom base, being provided with screwed hole in sleeve, the lower end of telescopic insulating post is provided with screw thread, and telescopic insulating post is threaded connection with sleeve；Being fixed with driven gear on described sleeve, driven gear side is engaged with driving gear, and described driving gear is connected with motor by rotating shaft.
As further program of the utility model: described upper bed-plate and lower bottom base connect by bracing frame is fixing.
As this utility model further scheme: described sleeve is provided with bearing with the contact position of lower bottom base.
As this utility model further scheme: described motor is fixed on the lower surface of upper bed-plate.
The beneficial effects of the utility model are the telescopic insulating cornice moving contacts that move on connecting lever and the separating and contact of static contact, it is achieved that opening a sluice gate and close a floodgate, whole process operation stable action, during combined floodgate, impulsive force is little, and the reliability of combined floodgate is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-the first insulation column, 2-static contact, 3-moving contact, 4-telescopic insulating post, 5-connecting lever, 6-hinge, 7-the second insulation column, 8-upper bed-plate, 9-bracing frame, 10-lower bottom base, 11-motor, 12-driving gear, 13-rotating shaft, 14-bearing, 15-sleeve, 16-driven gear.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of outdoor high-voltage alternating current isolating switch, including upper bed-plate 8 and lower bottom base 10, first insulation column the 1, second insulation column 7, movable touch knife and static contact 2 it is provided with on described upper bed-plate 8, described static contact 2 is fixed on the first insulation column 1 top, and described movable touch knife includes connecting lever 5 and the moving contact 3 being arranged on connecting lever 5 one end, the other end of described connecting lever 5 and the top of the second insulation column 7 are rotationally connected by hinge 6；It is movably hinged with telescopic insulating post 4 on the downside of the left end of described connecting lever 5, the lower end of described telescopic insulating post 4 is connected through upper bed-plate 8 with the sleeve 15 being positioned on lower bottom base 10, described sleeve 15 is provided with bearing 14 with the contact position of lower bottom base 10, it is provided with screwed hole in sleeve 15, the lower end of telescopic insulating post 4 is provided with screw thread, and telescopic insulating post 4 is threaded connection with sleeve 15；Being fixed with driven gear 16 on described sleeve 15, driven gear 16 side is engaged with driving gear 12, and described driving gear 12 is connected with motor 11 by rotating shaft 13.
