Abstract

The invention discloses a dynamic sealing device for an electric switch. The dynamic sealing device for the electric switch comprises a shell, a pair of magnetic poles and a sealing ring, wherein themagnetic poles are matched with an inner hole of the shell; an annular sealing groove is formed in the outer surface of each magnetic pole; and the sealing ring is embedded in the sealing grooves andcomprises a body and a plurality of elastic pieces. Due to the structure, the property of sealing between the magnetic poles and the shell is good.

Description

technical field [0001] The invention relates to a sealing device, in particular to a dynamic sealing device for an electric switch. Background technique [0002] Chinese patent CN200710147638.8 discloses a dynamic sealing device for medium and high voltage power switchgear. The action structure and the main shaft of the outdoor operating mechanism of the inflatable compartment, two bearings for installing the main shaft, at least one permanent magnet or at least two magnetic poles that are installed in cooperation with the inner hole of the housing and have a gap with the main shaft, The two magnetic poles are respectively located on both sides of the permanent magnet, the magnetic poles have a plurality of magnetic pole teeth, and a magnetic fluid is installed between the magnetic pole teeth of the magnetic poles and the main shaft, wherein the outer circles of the two magnetic poles A first sealing ring is installed on the top to ensure static sealing. [0003] The seali...
