Embodiment Construction

[0024] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] The specific embodiment of the pipe female supporting two-way fitting of the present invention is as Figure 1 to Figure 5 As shown, it includes flexible wire welding 7 for realizing the conductive connection between pipe bus 81 and pipe bus 82, insulator 3 for supporting flexible wire welding 7 and shielding the connection between pipe bus and flexible wire welding 7. Shielded fittings. The two ends of the flexible wire welding device 7 are provided with aluminum alloy castings to hold the corresponding pipe bus. angle. The flexible wire welding is fixedly connected on the upper flange of the insulator 3 through the flexible wire support 9 and is electrically connected with the upper flange of the insulator 3 .

[0026] The shielding fittings include a shielding spherical crown 1 (i.e., upper shielding fitting) installed above the connection b...

Abstract

The invention relates to a pipe busbar supporting two-way fitting and a shielding ring and a shielding spherical crown thereof, and aims to solve the problem of high probability of electric leakage in a connecting place between a grading ring and a supporting frame in prior art. The upper and lower shielding fittings of the pipe busbar supporting two-way fitting comprise connecting plate connecting structures which are used for connecting corresponding connecting plates, and also comprise sealing covers which are electrically connected with corresponding shielding fitting bodies, and can shield the connecting plates connected on the connecting plate connecting structures in the up-down direction. The connecting place between the shielding fittings and the supporting frame is fully shielded without causing accumulation of a large amount of electric energy; namely, the pipe busbar supporting two-way fitting provided by the invention is not subjected to an electric discharge phenomenon easily; and by virtue of the way of drilling holes in the lower sealing cover and fully plugging the upper sealing cover, the installation difficulty of the shielding fittings is lowered to the greatest extent while the shielding effect of the shielding fittings is ensured.

Description

technical field [0001] The invention relates to a pipe female supporting two-way fitting, a shielding ring, and a shielding spherical crown. Background technique [0002] In the layout of the converter station, the arrangement of two adjacent pipe busbars often forms a certain angle, and connecting fittings are required to connect the two pipe busbars at the angle. Corona is more likely to be generated at the connection between the connecting fittings and the pipe busbar, so shielding fittings that can shield the electric field at the included angle are also required. [0003] The shielding fittings in the DC field of the converter station in the prior art all adopt a double-ring shielding structure, that is, the upper shielding ring is set above the connection between the busbar and the connecting fittings, and the lower shielding ring is set below the busbar and the connecting fittings . When the position of the shielding ring is fixed, the shielding ring is fixedly conn...
