Insulation Device Component

Abstract: The invention provides a shock insulation device for overhead high-voltage equipment. The shock insulation device consists of a plurality of shock insulation device components(1) connected with one another, and a lower connecting board(2) is arranged at the lower part of the shock insulation device components(1) and connected with a top plate(6) of a frame(4) by bolts; an upper connecting board(3) is arranged at the upper part of the shock insulation device components(1) and is connected with a bottom plate(7) of the high-voltage equipment(5) by bolts; each shock insulation device component(1) consists of two semi-circular structures bended by a metal plate. The shock insulation device has small horizontal rigidity, but bigger vertical tension-compression rigidity, so that when the earthquake happens, the shock insulation device can resist the bigger upsetting moment generated by upper overhead equipment, simultaneously prolong the natural vibration period of the structure along the horizontal direction and reduce the earthquake response of the overhead high-voltage equipment, along with good resistance to capsizing and good shock insulation effect. The shock insulation device can be applied to all types of overhead high-voltage equipment of transformer stations, and the shock resistant and shockproof effects are obvious.
