Abstract

The invention provides a GIS device and a three-phase common box bus bar cylinder. The three-phase common box bus bar cylinder comprises a cylinder body, three single-phase attachment mounting holes are axially arranged in the cylinder body at intervals, single-phase attachment mounting flanges are arranged at the single-phase attachment mounting holes, and the flange is a neckless plate flange welded to the edge of a single-phase accessory mounting hole. Single-phase attachment mounting flanges are neckless plate flanges that have a reduced height compared to flanges with necks in the prior art, and under a condition that an axial distance between adjacent two single-phase attachment mounting flanges is unchanged, it is more conducive to extending to the junction of the single-phase attachment mounting flange and the bus bar body for the welding gun. The advantages are further demonstrated in miniaturized GIS devices where the cylinder body length is small and the length cannot be prolonged. The three-phase common box bus bar cylinder can be formed by welding and processing the cylinder body and the single-phase attachment mounting flanges. The casting method is not used, the cost is reduced, and the welding quality is more easily controlled.

Description

technical field

[0001] The invention relates to a GIS device and a three-phase common-box bus bar cylinder body thereof. Background technique

[0002] GIS equipment is the abbreviation of gas-insulated metal-enclosed switchgear. The components composed of the busbar structure and the isolating switch and circuit breaker connected to the busbar structure in the GIS equipment are called intervals. The busbar structure includes a three-phase common box busbar cylinder. For miniaturized GIS equipment, such as 252kV miniaturized GIS equipment, the length of the interval (or three-phase common tank busbar cylinder) is less than 1.6 meters, and its structure is particularly compact. The structure of the three-phase common tank busbar cylinder is as follows figure 1 and figure 2 As shown, the cylinder body of the three-phase common box busbar includes a cylinder body, and three single-phase accessory installation holes (not shown in the figure) are arranged at intervals along the ...

Embodiment Construction

[0031] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0032] The specific embodiment of GIS equipment of the present invention, as Figure 3 to Figure 13 As shown, the GIS equipment includes a three-phase common box busbar barrel 1, and the three-phase shared box busbar barrel includes a barrel body 11, and three single-phase Attachment mounting holes 6, single-phase attachment mounting flanges 13 are fixedly installed on the edges of the three single-phase attachment mounting holes 6, and pot insulators 2 are installed on the single-phase attachment mounting flanges 13, which are also used for installation isolation Structures such as switches or circuit breakers. In the present invention, the single-phase accessory mounting flange 13 is a neckless plate flange. Compared with the necked flange in the prior art, the height of the plate flange is lower, which can reduce the size of the single-phase accessor...
