Abstract
The utility model discloses a disconnecting switch. An upper hinge joint point and a lower hinge joint point are opposite in a vertical direction. When switching off is in place, a central section hinge joint point is located on one side of an installation frame, wherein the side is opposite to an insulated plate. When switching on is in place, the central section hinge joint point is located on one side of the installation frame, wherein the side is opposite to an operation mechanism, and an upper compressed spring and a lower compressed spring are in a compressed state. During switching off and switching on processes, motion of a transmission rod drives the central section hinge joint point to shuttle between the two sides of the installation frame and carry out reciprocating motion. Because the upper compressed spring and the lower compressed spring are in the compressed state, elastic potential energy is stored. When the central section hinge joint point offsets lines where the upper hinge joint point and the lower hinge joint point are located, the upper compressed spring and the lower compressed spring release the elastic potential energy to carry out work on the central section hinge joint point. During a switching off process, a contact knife acquires an accelerated speed, a rotating speed is accelerated and the switching off process is accelerated too so that a distance of the contact knife and a contact end is increased rapidly, a free gas density is reduced, an arc is extinguished rapidly and arc extinguishing is accelerated.
