Embodiment 1

[0033] Such as figure 1 , figure 2 As shown, the solid insulated bus bar in this embodiment includes a central power conductor 2 and an outer insulating resin layer 4. In order to solve the problem that the insulating resin layer 4 is not easy to cast and solidify on the smooth power conductor 2, in this embodiment, An elastic insulating layer 3 is set on the transmission conductor 2, and the elastic insulation layer 3 is specifically an insulating rubber layer, which is fixed on the transmission conductor 2 by the elastic force of the elastic insulating layer 3, and then the insulating resin is cured on the elastic rubber layer 3. Can.

[0034] It should be noted that the elastic insulating layer 3 can not only play a fixing role, but also have the ability to absorb the expansion and contraction of the power transmission conductor caused by thermal expansion and contraction when the power transmission conductor 2 is long. The elastic insulating layer is designed as a hollo...

Embodiment 2

[0042] Such as image 3 and Figure 4 As shown, the structure of the solid insulated bus bar in this embodiment is the same as that of Embodiment 1 in that: the power transmission conductor 2, the elastic insulating layer 3 and the insulating resin layer 4 are arranged once from the inside to the outside, and the difference from that of Embodiment 1 The main point is that a protective cylinder 52 is provided outside the equal-diameter section 42 of the insulating resin layer 4, and the protective cylinder 52 and the throat-shrinking cylinders at both ends of the connecting cylinder 51 are connected together to form a sleeve wrapped in insulating resin. The outer cylinder outside the layer and the middle protective cylinder 52 are set on the equal-diameter section 42 of the insulating resin layer. Since the size of the equal-diameter section is relatively small, the protective cylinder 52 can directly use a pipe profile without special Weld large size barrels.

Embodiment 3

[0044] Such as Figure 5 and Figure 6 As shown, the structure of the solid insulated bus bar in this embodiment is the same as that of Embodiment 1 in that: the power transmission conductor 2, the elastic insulating layer 3 and the insulating resin layer 4 are arranged once from the inside to the outside, and the two sides of the insulating resin layer 4 The ends are respectively provided with a connecting cylinder 1. The difference from Example 2 is that the protective cylinder here includes an inner protective buffer layer 7 and an outer protective armor layer 8, and the protective buffer layer 7 is wrapped in an insulating resin layer. 4, in fact, the insulating resin layer 4 and the power transmission conductor 2 are strong enough to ensure the strength of the busbar. The protective buffer layer and protective armor layer are mainly to prevent bumps and scratches during transportation and installation.

[0045] In fact, in the above three embodiments, the two axial ends ...

Abstract

The invention relates to a solid insulation bus including a transmission conductor and an insulation resin layer at the outer side, and further includes an elastic insulating layer fixedly sleeving the transmission conductor, and the insulation resin layer is solidified at the circumferential outer side of the elastic insulating layer. The elastic insulating layer is fixed on the transmission conductor by means of the elastic force of the elastic insulating layer, and then the insulation resin is solidified on the elastic rubber layer to facilitate the solidification of the insulation resin layer on the transmission conductor, so that the molding quality of the solid insulated bus can be effectively guaranteed. Moreover, the elastic insulating layer can not only play a role for fixing, but also has the capability of deforming and absorbing the expansion and contraction caused by the thermal expansion and contraction of the transmission conductor when the transmission conductor is long, so that the bearing of the whole solid insulation bus can be effectively improved.

Description

technical field [0001] The invention relates to a solid insulated busbar. Background technique [0002] At present, the common gas-insulated metal-enclosed switchgear busbar and gas-insulated pipeline busbar have a structure such as the pipeline busbar of gas-insulated metal-enclosed switchgear provided in the Chinese utility model with the authorized announcement number CN205543717U. The pipeline busbar includes an outer tube, There are conductors in the outer tube, and flanges are installed at both ends of the outer tube to realize the connection between the pipeline busbars through flange connection, and contacts are respectively set at both ends of the conductors to realize the connection between the adjacent pipeline busbars and the pipeline busbars. The point-to-point connection between the pipeline busbar and the corresponding product body. But this pipeline bus needs to fill the pipeline with SF 6 , mixed gas and other greenhouse gases are used as insulating gases,...
