Abstract
The utility model relates to an open-close busbar insulation casing. The hollow insulation casing is used for it and is divided into internal and external layers, the internal layer is rectangle hollow insulation sleeve, and the external layer is assembled by a semicircle sleeve into the hollow insulating sheath, the rectangle hollow insulation sleeve as the internal layer through the convex blocks of its outer surface is beset inside the positioning slot in the semicircle sleeve of the external layer so that the rectangle hollow insulation sleeve is integrated with the hollow insulating sheath composed of the semicircle sleeve. The rectangle hollow insulation sleeve is provided with a ring slot. The semicircle sleeve is provided with a groove and with a fixed convex table, which is provided with a fixed convex hole. The utility model has advantages of that the layout and design are new and the structure is reasonable, and that it can meet the requirement that the main busbar of 10 kV high voltage switching equipment can be directly installed from the upper part of the equipment as a whole. It is suited to 10 kV high voltage switching equipment to be installed against the wall, not only facilitating the installation of the main busbar of high voltage equipment but also satisfying the insulation requirements of the main busbar and at the same time facilitating maintenance.
Description
Technical field
The bus insulation that the utility model relates to a kind of 10kV of being used for high voltage switchgear supports, particularly separating-closing type bus insulation sleeve pipe.It is suitable for the 10kV high voltage switchgear and uses.
Background technology
The bus insulation that existing 10kV high voltage switchgear uses supports, and be referred to as usually: bus insulation sleeve pipe, its structure are integral type, can not separate.The bus insulation sleeve pipe of this structure, in actual use, the applicant finds: during the main bus bar of erection unit, it can not satisfy the top integral installation requirement of the direct slave unit of main bus bar.Usually the main bus bar mode of installing, can only be side at equipment from an end, the bus insulation sleeve pipe on the equipment of being pre-installed in order; Perhaps take bus sectional lized mode to install, main bus bar is divided into the short multistage bus of size, again by a section link up of bolt.This dual mode is installed main bus bar and is all had bigger disadvantage.Mode one, the main bus bar integral installation, need vacate than large space at an end of place apparatus, main bus bar for the ease of the installation dimension overlength, sometimes also need perforate on the body of wall of building, it is run through to being arranged on indoor equipment from outdoor, and time-consuming like this, workmen's sesame fatigue resistance is big.Mode two, the main bus bar segmentation is installed, and can cause the main bus bar interface too much, and main bus bar generates heat easily, and increase the fault point.For safety has been buried hidden danger.And all can not lean on wall to install, otherwise can cause difficulty to service work by the equipment that this dual mode is installed main bus bar.
The technology contents of utility model
The purpose of this utility model is improved at above-mentioned the deficiencies in the prior art, proposes and design separating-closing type bus insulation sleeve pipe.
Technical solution of the present utility model, adopt hollow insulating sleeve, it is characterized in that, hollow insulating sleeve is divided into inside and outside two-layer, internal layer is rectangular hollow insulating case, outer constitute hollow insulating sleeve, be embedded in the location notch in the outer field semicircle cover, make rectangular hollow insulating case and the hollow insulating sleeve be made up of the semicircle cover is integrated as the rectangular hollow insulating case of the internal layer protruding square by its outer surface by the assembly unit of semicircle cover.
It is characterized in that on the rectangular hollow insulating case cannelure being arranged.
It is characterized in that semicircle puts fluted.
It is characterized in that semicircle has put fixing lug boss.
It is characterized in that fixing lug boss is provided with fixing hole.
The utility model has the advantages that, modern design, rational in infrastructure, the requirement of integral installation is carried out on the direct slave unit of the main bus bar top that can satisfy the 10kV high voltage switchgear.Its 10kV high-voltage switch gear equipment that is suitable for needing to install by wall uses.Both made things convenient for the employed main bus bar of high-tension apparatus to install, and satisfied the required insulating requirements of main bus bar again, convenient simultaneously maintenance is worthy of popularization.

Embodiment
Below, with reference to the accompanying drawings, describe the utility model embodiment in detail.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the utility model is by adopting hollow insulating sleeve, and hollow insulating sleeve is divided into inside and outside two-layer, and internal layer is rectangular hollow insulating case 1, and protruding square 6, cannelure 2 are arranged on the outer surface of rectangular hollow insulating case 1.Cannelure 2 is at rectangular hollow insulating case 1 two-end part.Cannelure 2 has a plurality of, and the effect of cannelure 2 is the creepage distances that increase rectangular hollow insulating case 1 surface.Skin by semicircle cover 5,7 assembling combination together, constitute the hollow insulating sleeve that rectangular hollow insulating case 1 is installed, during the ectonexine combination, the protruding square 6 of rectangular hollow insulating case 1 by its outer surface is embedded in the location notch 9 on the inwall that is combined into outer field semicircle cover 5,7, make rectangular hollow insulating case 1 and be integrated, can not go here and there by semicircle cover 5, the 7 hollow insulating sleeves of forming.On the semicircle cover 5,7 fluted 4.Groove 4 has many, and the effect of groove 4 also is in order to increase the creepage distance on semicircle cover 5,7 surfaces.On the semicircle cover 5,7 fixing lug boss 3 is arranged.Fixing lug boss 3 is provided with fixing hole 8.Fixing hole 8 has a plurality of.When using the utility model that bus is installed, earlier outer field semicircle cover 7 is fixed on the high-tension apparatus, all be enclosed within needed primary insulation sleeve pipe 1 on the bus then, again bus is put into outer field semicircle cover 7 together with the primary insulation cover, after main bus bar and branch bar are fixing, again second half outer layer insulation cover 5 is pressed on the primary insulation cover 1 from top to bottom, combines, and be fixed on the high-tension apparatus and get final product with semicircle cover 7.
