Shielding structure, insulator and switchgear

The invention relates to a shielding structure, an insulator and switch equipment, the shielding structure comprises two shielding parts, each shielding part comprises an arc-shaped arc-shaped piece, the two arc-shaped pieces are located on the circumference of the same reference circle and are symmetrically arranged around the reference circle center, and the space between the two arc-shaped pieces is used for arranging a conductor. The arc-shaped part is grounded, and a certain potential is given to the arc-shaped part through grounding, so that the leaked current of the insulator is stabilized, the surface electric field distribution of the insulator is improved, and gap discharge and surface flicker are reduced. Thus, the shielding structure intersects with a traditional grounding shielding ring, ground potential shielding of the conductor can be achieved only through the two shielding parts, the space size occupied by the shielding structure is greatly reduced, then the space size of the insulator is red
