Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
The specific embodiment of the insulation cover plate of the utility model, as shown in Figures 3 to 5, insulation cover plate 101 include plate body 5
With the fixation hole 12 being arranged on plate body 5, fixation hole 12 is used to insulation cover plate 101 being fixed on gas-insulated switchgear.
Plate body 5 has for towards the medial surface 11 inside gas-insulated switchgear, medial surface 11 to be equipped with circumferential seal slot 6, week
Circumferential seal structure is constituted to seal groove 6, to guarantee the sealing performance of the cylinder of insulation cover plate and gas-insulated switchgear,
In other embodiments, cylinder is equipped with circumferential seal slot, and medial surface is equipped with matches with the sealing ring sealing in circumferential seal slot
The sealing of conjunction, sealing constitute circumferential seal structure.The cone 7 in circumferential seal slot 6 is convexly equipped on medial surface 11,
The conical surface 8 of cone 7 is constituted for the drainage face to the high temperature hot gas stream drainage generated in gas-insulated switchgear interrupting process.
Compared with prior art, by the way that protruding plate is arranged on side of the insulation cover plate towards the side inside gas-insulated switchgear
The cone of body drains the high temperature hot gas stream generated in gas-insulated switchgear interrupting process by drainage face, reduces height
Impact and ablation of the air-flow to insulation cover plate are warmed, the service life of insulation cover plate is improved, reduces costs.
For the ease of draining to high temperature hot gas stream, in the present embodiment, cone 7 is circular cone, to guarantee that high temperature hot gas stream is suitable
Benefit 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 middle position of insulation cover plate, in order to which most of high temperature hot gas stream is drained
It goes, in the present embodiment, the middle position of plate body 5 is arranged in cone 7, to reduce the impact and ablation to insulation cover plate.
In order to avoid link position of the high temperature hot gas stream to plate body and cylinder is impacted and destroy between plate body and cylinder
Sealing performance, in the present embodiment, plate body 5 is also convexly equipped with the annular arranged around cone 7 on the medial surface 11 where cone 7
Protrusion 9, annular protrusion 9 are arranged in circumferential seal slot 6.Annular protrusion can block the high warm to come is drained from drainage face
Air-flow avoids high temperature hot gas stream from impacting the link position of plate body and cylinder and destroys the leakproofness between plate body and cylinder
Can, to avoid leaking out the intracorporal insulating gas of cylinder.In addition, the high temperature hot gas stream drained away from drainage face encounters ring
It can be flowed by with original opposite direction after shape protrusion, so as to be interfered with the high temperature hot gas stream of original direction, from
And generate turbulent flow.In other embodiments, annular protrusion can be arranged on drainage face, or is not provided with annular protrusion.This
In embodiment, along there are two being arranged radially of cone 7, two annular protrusions 9 and plate body 5 surround to be made from drainage face annular protrusion 9
The high-temperature gas of outflow is in the annular groove 10 of turbulent condition.The thermal current flowed back out in annular groove and the hot gas gone out from drainage surface current
Stream is mutually impacted in the endface of the one end of annular protrusion far from plate body, turbulent flow is generated, to slow down the diffusion of high temperature hot gas stream simultaneously
The energy that can reduce high temperature hot gas stream avoids the inner surface of cylinder from generating flashover.It in other embodiments, can only setting one
A annular protrusion.
In the present embodiment, it is being all insulating cover made of epoxy resin that the material of insulation cover plate 101, which is epoxy resin material,
In the case of plate, the insulation cover plate 101 in the present embodiment is convexly equipped with cone 7 and annular protrusion 9, improves the intensity of insulation cover plate,
Service life is increased, is reduced costs.
The specific embodiment of the gas-insulated switchgear of the utility model, the gas-insulated switchgear in the present embodiment
