Abstract

The invention provides a movable conducting block and a solid-sealed polar pole. The movable conducting block comprises a lower conducting block, an upper conducting block, a conductive pole and flexible links, wherein the lower conducting block is provided with a first through hole; the upper conducting block is provided with a coaxial second through hole of the first through hole; the conductive pole penetrates into the first through hole and the second through hole; one end of each flexible link is fixed to the upper conducting block, and the other end of the flexible link is fixed to the lower conducting block; the flexible links are used for forming the electric connection between the upper conducting block and the lower conducting block. The movable conducting block can avoid temperature rise, and reduce the cost.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a dynamic conduction block and a solid-sealed pole. Background technique [0002] In the field of medium and high voltage electrical appliances, vacuum circuit breakers are electrical equipment used to control and protect power systems, and the solid-sealed poles including vacuum interrupters are the core components of vacuum circuit breakers. [0003] Chinese patent announcement number CN201332052Y discloses a solid-sealed pole, such as figure 1 As shown, it includes an insulating shell 1, an upper bracket 2 for introducing current, a vacuum interrupter 3, and a lower bracket 4 for outputting current. The static contact of the vacuum interrupter 3 is electrically connected to the upper bracket 2, and the vacuum interrupter 3 The moving conductive rod 5 is electrically connected with the lower bracket 4 through the moving sliding rod 6 . The lower end of the movable conductive...
