Embodiment Construction

[0024] The high-voltage wall bushing provided by the present invention includes a bushing, a connecting flange arranged on the bushing, and a conductor arranged in the bushing and passing through the connecting flange, wherein the high-voltage wall bushing of the present invention The sleeve also includes a stretching device connected with the conductor.

[0025] The high-voltage wall bushing provided by the present invention is provided with a stretching device 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 the conductor is installed non-vertically, so that The conductor is kept as straight as possible to ensure the effective insulation distance between the conductor and the casing, thereby reducing the probability of discharge of the casing and improving the reliability of the casing.

[0026] In order to make the purpose, advantages and features of the present invention clear...

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 bushing. Background technique [0002] In the technical field of high-voltage electrical appliances, high-voltage wall bushings are devices that lead high-voltage power supplies through walls, from indoors to outdoors or from outdoors to indoors, or high-voltage switches or transformers through the shell wall to guide high-voltage power. [0003] figure 1 An existing high-voltage wall bushing is shown. Such as figure 1 As shown, the existing high-voltage through-wall bushing includes a bushing 1, a conductor 2 installed inside the bushing 1, and a connecting flange 3 sleeved on the conductor 2. The connecting flange 3 is arranged on the bushing 1 The end is connected with the sleeve 1. In the prior art, since the length of the conductor 2 is relatively long, when it is placed horizontally, under the influence of its own gravity, it will b...
