Specific implementation mode
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The specific embodiment of the insulation cover plate of the present invention, as shown in Figures 3 to 5, insulation cover plate 101 include plate body 5 and set
The mounting hole 12 on plate body 5 is set, mounting hole 12 is used to insulation cover plate 101 being fixed on gas-insulated switchgear.Plate body 5
With for towards the medial surface 11 inside gas-insulated switchgear, medial surface 11 to be equipped with circumferential seal slot 6, circumferential seal
Slot 6 constitutes circumferential seal structure, to ensure the sealing performance of the cylinder of insulation cover plate and gas-insulated switchgear, at other
In embodiment, cylinder is equipped with circumferential seal slot, and medial surface is equipped with close with the sealing ring sealing cooperation in circumferential seal slot
Envelope portion, sealing constitute circumferential seal structure.The cone 7 in circumferential seal slot 6, cone 7 are convexly equipped on medial surface 11
The conical surface 8 constitute for generated in gas-insulated switchgear interrupting process high temperature hot gas stream drainage drainage face.With it is existing
There is technology to compare, passes through the setting protrusion plate body on side of the insulation cover plate towards the side inside gas-insulated switchgear
Cone makes the high temperature hot gas stream generated in gas-insulated switchgear interrupting process be drained by drainage face, reduces high warm
Impact and ablation of the air-flow to insulation cover plate, improve the service life of insulation cover plate, reduce cost.
For the ease of being drained to high temperature hot gas stream, in the present embodiment, cone 7 is circular cone, to ensure that high temperature hot gas stream is suitable
Profit drains away, to reduce impact and ablation of the high temperature hot gas stream to insulation cover plate.In other embodiments, cone 7 is rib
Cone or frustum.Since high temperature hot gas stream concentrates on the centre position of insulation cover plate, in order to which most of high temperature hot gas stream is drained
It goes, in the present embodiment, cone 7 is arranged in the centre position of plate body 5, to reduce impact and ablation to insulation cover plate.
