Embodiment Construction

[0024] The high-voltage wall-piercing bushing provided by the present invention includes a bushing, a connecting flange disposed on the bushing, and a conductor disposed in the bushing and passing through the connecting flange, wherein the high-voltage wall-penetrating bushing of the present invention The bushing also includes tensioning means connected to said conductor.

[0025] In the high-voltage wall-through bushing provided by the present invention, a stretching device is arranged at one or both ends of the bushing, and the conductor is stretched by the stretching device to offset the influence of the conductor's own gravity when it is not vertically installed, so that The conductor is kept in a straight line as much as possible to ensure the effective insulation distance between the conductor and the bushing, thereby reducing the discharge probability of the bushing and improving the reliability of the bushing.

[0026] In order to make the purpose, advantages and chara...

Abstract

The present invention provides a high-voltage wall bushing including a bushing, a connecting flange arranged on the bushing, and a conductor arranged in the bushing and passed through the connecting flange, wherein, the high-voltage wall bushing also includes a stretching device connected to the conductor. The high-voltage wall bushing overcomes a droop problem of the conductor caused by an own weight at non-vertical mounting through a tensile force provided by the stretching device so that the conductor keeps in a straight line state as soon as possible at non-vertical mounting, and thereby avoiding a gas gap or a discharging problem of an insulating surface of a solid body caused by a shortened distance between the conductor and the bushing, and preventing the bushing from being damaged and improving a reliability of the high-voltage wall bushing for usage. The arrangement of the stretch device enables the high-voltage wall bushing to cancel an insulating supporter for the conductor, and thereby ensuring the reliability of the high-voltage wall bushing efficiently.

Description

technical field [0001] The invention relates to the technical field of high-voltage electrical appliances, in particular to a high-voltage wall-piercing bushing. Background technique [0002] In the technical field of high-voltage electrical appliances, the high-voltage wall bushing is a device that passes the high-voltage power supply through the wall and leads it from indoors to outdoors or from outdoors to indoors, or a device for high-voltage switches or transformers to pass through the shell wall inside and outside to guide high-voltage power supply. [0003] figure 1 An existing high voltage wall bushing is shown. Such as figure 1 As shown, the existing high-voltage wall bushing includes a bushing 1, a conductor 2 installed inside the bushing 1, and a connecting flange 3 sleeved on the conductor 2, and the connecting flange 3 is arranged on the bushing 1. end, and connect with sleeve 1. In the prior art, due to the long length of the conductor 2, when it is placed ...
