Embodiment Construction

[0025] refer to figure 2 , the main elements included in the present invention are the central conductor 11, which is actually a rod; the ground guide 12; and the solid synthetic insulating material 13. This material surrounds the majority of the center conductor 11 (i.e., in an amount sufficient to transmit mechanical forces from the rods making up the center conductor 11 to the insulating material 13), and the insulating material also surrounds the end of the guide 12 from the outside, in an amount sufficient to The mechanical force is transmitted from the insulating material 13 to the guide 12 . However, an annular space 14 is formed between the inner surfaces of the guides 12 , in particular in the region of their ends 20 , so that a dielectric fluid can be introduced into the annular space 14 .

[0026] The annular space 14 is arranged to have a thickness of not less than 10 mm. This space or spacing distance from the center conductor 11 to the guide 12 is defined as a...

Abstract

The invention relates to a device used for controlling high electric field in synthetic insulating material and providing high-degree dielectric reliability and leak tightness. The invention provides an annular space (14) between the inner surface of a gate apparatus (12) and the central part (31) of large amount of dielectric medium insulating materials (13); wherein, the gate apparatus (12) inarches ground and surrounds a center conductor in a great measure (11); the great measure (11) and the gate apparatus (12) inlays in the large amount of dielectric medium insulating materials (13). The sulphur hexafluoride (SF6) which is a dielectric medium fluid or oil are filled in the annular space (14). The device used for controlling high electric field is applied in sealed and high-pressure electric bushing.

Description

technical field [0001] The present invention relates to the transmission of electric current at medium or high voltage, and in particular to a sealing bushing made of synthetic insulating material and utilizing a guide around a conductor. [0002] More precisely, the invention relates to bushings submerged internally or externally and having synthetic insulation, the internal or external end of which is arranged to be installed in ambient air, so that it is subject to environmental conditions, while its The other end is set to be immersed in, for example, oil or sulfur hexafluoride (SF 6 ) in the insulating medium. [0003] Another possible application is insulating plugs or insulating supports. Background technique [0004] In devices for transmitting power at medium voltages, it is known to control the electric field inside an insulation system such as a sealed bushing by using an electric field director. [0005] It should be recalled that the function of a bushing is ...
