Turnover type high-voltage switch

Abstract

The invention discloses a turnover type high-voltage switch which comprises a rotating system, a springback system and an overturning system, wherein the rotating system is a basic device; the rotating system is a mounting platform for the springback system and the turnover system; a first connector is arranged on the rotating system, and a second connector is arranged on the overturning system and connected with two sections of wires respectively; when disconnection operation needs to be conducted, the sliding electric cylinder conducts telescopic control to achieve separation of the semi-spherical groove and the guide column 104, and the arc electric cylinder conducts telescopic control to enable the guide column to rotate and be away from the semi-spherical groove to achieve disconnection. When closing operation needs to be conducted, the extension spring and the lower spring are in a pulled state at the moment, the inner spring and the outer spring are in a pressed state, the springs rebound to enable the guide column to return to the position below the semispherical groove, and the sliding electric cylinder stretches out and draws back to control the semispherical groove to beattached to the guide column. The relative position between the movable block and the inserting plate can be adjusted by adjusting the double plug pins, and the position of the adjusting block can beadjusted by adjusting the U-shaped plug pins, so that the pre-tightening force of the spring is controlled, and the spring rebounds to enable the movable arc block to return to the initial position.

Description

technical field [0001] The invention relates to the technical field of high-voltage switches, in particular to a flip-type high-voltage switch. Background technique [0002] In the process of power transmission, it is usually equipped with a high-voltage switch, which can cut off or close the no-load current and coincident current in the circuit, and when the system fails, it will cut off the overload current and short-circuit current through the function of the relay protection device. The safety factor of power transmission is greatly improved. In order to further improve the safety factor of the switch, multiple disconnection modes are added, and a flip-type high-voltage switch is designed. In order to solve this problem, the application number: CN201711365624.3 announced a high-voltage switch three-phase Mechanical locking device and power frequency signal source, but the design does not disclose the specific structure, and it cannot realize multiple guarantees and autom...
