Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection range of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment, is shown in shown in Fig. 1 to Fig. 4: a kind of oil-immersed and high-voltage on-load switch, comprises Switch main body 10, turning handle 20, switch shaft 30, sealed fixing device, upper cover plate 40, lower cover 41, rotor 42, gear frame 43, extension spring 44 and centering block assembly; Switch main body 10 is positioned at the bottom of lower cover 41, and the center line of Switch main body 10 overlaps with the center line of switch shaft 30, and this concentric structure arranges and can reduce overall volume, is beneficial to and installs and dismounting.Turning handle 20 is located at the top ends of switch shaft 30, is spirally connected fixing between it by screw, and like this when rotating turning handle 20, switch shaft 30 also can along with rotating together.Sealed fixing device is positioned at the outer peripheral face of switch shaft 30, and itself and transformer box wall 60 are fixedly installed, and sealed fixing device has the effect preventing leakage of oil, and it comprises fixed cover 50, nut 51, sealing ring 1 and sealing ring 2 53; Switch shaft 30 offers groove, and sealing ring 1 is arranged in groove, and its outer end abuts with the inner face of fixed cover 50; Fixed cover 50 is set in the outer peripheral face of switch shaft 30 and runs through transformer box wall 60, and be spirally connected fixing and its end face of nut 51 and fixed cover 50 abuts with the upper surface of transformer box wall 60 and coordinates; Sealing ring 2 53 is located in the groove on fixed cover 50, and its other end abuts with the lower surface of transformer box wall 60 and coordinates.Above-mentioned switch shaft 30 run through upper cover plate 40 and with rotor 42 collaboration, rotor 42 can be taken like this when switch shaft 30 rotates to and rotate accordingly.Upper cover plate 40 and lower cover 41 are respectively arranged with installing hole, are interconnected by screw 47 between installing hole opposing upper and lower, upper cover plate 40 and lower cover 41 can be allowed like this to be fixedly connected with.Rotor 42 and gear frame 43 are arranged between upper cover plate 40 and lower cover 41 and it is linked by extension spring 44, and centering block assembly to be arranged on upper cover plate 40 and its respectively with rotor 42 and gear frame 43 collaboration; Centering block assembly comprises large centering block 45 and little centering block 46, large centering block 45 and little centering block 46 all rotate be arranged on upper cover plate 40 and its all with rotor 42 and gear frame 43 collaboration.In use, when switch need from co-bit put go to point position time, rotation turning handle 20, allows switch shaft 30 drive rotor 42 to rotate, corresponding rotor 42 drives little centering block 46 to rotate, then drives gear frame 43 rotation to make extension spring 44 be in energy storage state by little centering block 46; When the angle formed between rotor 42 and gear frame 43 is 90 °, the elastic energy of extension spring 44 can release suddenly, allows rotor 42 and gear frame 43 quick rotation, realizes the effect of separating brake.Same, when switch need to go to from a point position co-bit put time, rotate backward turning handle 20, allow switch shaft 30 drive rotor 42 to rotate backward, at this moment rotor 42 drives large centering block 45 to rotate, and allows large centering block 45 drive gear frame 43 to rotate and makes extension spring 44 be in energy storage state, when the angle formed between rotor 42 and gear frame 43 is 90 °, the elastic energy of extension spring 44 can discharge suddenly equally, allows rotor 42 and gear frame 43 quick rotation, realizes the effect of closing a floodgate.
