Power switch containing liquid metal

Abstract

The invention relates to the field of switches, the invention further discloses a power switch containing liquid metal. The power switch comprises a cylindrical barrel, a control structure, a first electrode, a movable liquid storage structure, a first telescopic structure, liquid metal and a second electrode, and the control structure comprises a push rod motor, a first rotating structure and a second rotating structure; the push rod motor is detachably connected to the upper end of the cylindrical barrel; the second rotating mechanism is rotationally connected to the output end of the push rod motor; the first rotating mechanism controls the second rotating mechanism to rotate; the liquid metal is filled in the cylindrical barrel; the second rotating mechanism can carry the movable liquid storage structure to move up and down; the upper end of the first telescopic structure is fixedly connected to the inner top wall of the cylindrical barrel; the lower end of the first telescopic structure is fixedly connected with the movable liquid storage structure, the first electrode is electrically connected with the movable liquid storage structure, the second electrode is electrically connected with the liquid metal, electric arcs generated at the moment of connection and disconnection of an electrical path between the first electrode and the second electrode act on the liquid metal,and the service life of the switch contact is prolonged.

Description

technical field [0001] The invention belongs to the field of electricity, in particular to a power switch containing liquid metal. Background technique [0002] The power switch is a device used to close or break the circuit in the power system. The existing power switch is always inseparable from the metal solid-state switch blade, and it is always difficult to avoid arcing after the power switch is disconnected and closed. Existence, arcing is easy to cause surface oxidation of solid metal switch knife, vaporization of part of the surface, surface deformation, surface smoothness changes, resulting in deterioration of switching electrical characteristics, and the loss caused by arcing of switches that are often on-off is quite serious. And not safe. Contents of the invention [0003] The invention provides a power switch containing liquid metal, which can solve the above technical problems and has the advantage of prolonging the service life of the switch. [0004] The ...
