Embodiment 1

[0048] Such as Figure 1 to Figure 5 As shown, the insulating support plate includes an insulating plate 53 , a metal flange 100 and a central insert 51 , the insulating plate 53 is cured and formed by epoxy resin material, and the metal flange 100 is detachably fixed on the outside of the insulating plate 53 . Specifically, the insulating plate 53 is embedded with an embedded nut 52, and the metal flange 100 is provided with an insulating plate connecting hole 101, and the insulating plate connecting bolt 12 passes through the insulating plate connecting hole 101 and is threadedly connected with the embedded nut 52, and The metal flange 100 is fixed on the insulating plate 53 . The above-mentioned metal flange 100 is the metal connecting plate in this embodiment, the embedded nut 52 is the metal insert in this embodiment, and the central insert 51, the embedded nut 52 and the insulating plate 53 are molded integrally through a mold.

[0049] Such as image 3 and Figure 4 ...

specific Embodiment 2

[0059] Compared with the specific embodiment 1 of the insulating support plate of the present invention, the difference mainly lies in: as Figure 8 to Figure 12 As shown, the metal connecting plate 10 in this embodiment is an arc-shaped plate, and the metal connecting plate 10 is provided with a flange connection hole 102, and the flange connection hole 102 is used to be fixedly connected to one of the cylinders by bolts.

[0060] Such as Figure 12 to Figure 14 Shown is a schematic diagram of the structure of the insulating support plate 5 applied to the gas insulation cylinder assembly in this embodiment. The first cylinder flange 14 on the first cylinder 1 has a sealing fitting part and a support arranged inside the sealing fitting part. Connecting part, the insulating support plate 5 is connected to the supporting connection part of the first cylinder flange 14, and the sealing fit between the second cylinder flange 21 on the second cylinder 2 and the first cylinder flang...

specific Embodiment 3

[0067] Compared with the specific embodiment 1 of the insulating support plate of the present invention, the main difference is that the extension direction of the connecting hole of the insulating plate and the connecting hole of the cylinder in this embodiment are perpendicular, that is, the connecting hole of the insulating plate is along the radial direction of the central insert. extend. At this time, the two orifices of the connecting hole of the insulating plate are respectively located on the outer peripheral surface and the inner peripheral surface of the metal flange, and the processing of the connecting hole of the insulating plate needs to be carried out along the radial direction of the metal flange, which has the problem of inconvenient positioning of the metal flange; in addition When fixing the insulating plate and the metal flange, since the connecting hole of the insulating plate extends radially along the central insert, it is inconvenient to align the insert...

Abstract

The invention relates to a gas insulation cylinder assembly and an insulation support plate thereof. The insulation support plate comprises an insulation plate formed by curing an insulation material,a central insert embedded in the insulation plate, a metal connecting plate fixed on the insulation plate, and a metal insert embedded in the insulation plate. The metal connecting plate is providedwith an insulation plate connecting hole, and the insulation plate connecting hole is used for being fixedly connected with the metal insert through a fastener so as to fix the metal connecting plateon the insulation plate. During actual processing, only a certain number of metal inserts need to be arranged at the joint of the insulation plate and the metal connecting plate at intervals, and compared with the prior art, the area, prone to cracking, between the insulation plate and the metal connecting plate is greatly reduced, so that the risk of cracking at the joint of the insulation plateand the metal connecting plate is reduced.

Description

technical field [0001] The invention relates to a gas insulation cylinder assembly and its insulation support plate. Background technique [0002] With the development of my country's electric power industry and the acceleration of power grid construction, SF 6 Gas-insulated metal-enclosed gas-insulated switchgear (hereinafter referred to as GIS) has also been widely used. As a key component of GIS equipment, the insulating support plate has a great impact on the long-term live performance of the product. According to statistics, about 40% of power outage accidents are caused by insulating parts. The insulating support plate is generally composed of a central insert, a metal flange, and an insulating plate connecting the central insert and the metal flange. In GIS, it mainly plays the role of air chamber distinction, conductor support, main insulation resistance, normal and short circuit resistance important role of current. Divided by function, the insulating support pla...
