Embodiment Construction

[0034] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] Specific embodiment 1 of the high-voltage electrical equipment of the present invention, such as Figure 2 to Figure 8 As shown, the high-voltage electrical equipment includes an equipment base on which a high-voltage bushing is installed, and the high-voltage bushing of the present invention is a 550kV high-voltage bushing. The high-voltage bushing includes a sleeve body 3 and a high-voltage conductor 2 arranged at the center of the sleeve body 3. A high-potential flange 1 is installed on one end of the sleeve body 3, and a low-potential flange 5 is installed on the other end. The high-voltage conductor 2 is installed on the high-voltage bushing. On the potential flange 1, the shielding tube 4 is worn on the high-voltage conductor 2 and the lower end is installed on the low-potential flange 5. Shielding tube 4 between body 3, shed skirt 33 is di...

Abstract

The invention relates to a high-voltage bushing and high-voltage electrical equipment of using the same. A mean field section is set into a smooth shape, is relatively regular in shape and is free ofa protruding tip, so that the electric field intensity of an electric field at various positions on the mean field section is basically the same when the mean field section is in the electric field, and the maximum electric field intensity on a sleeve body is relatively reduced, thereby ensuring the insulating capacity of the high-voltage bushing, avoiding the flashover phenomenon of the high-voltage bushing and improving the security level of the high-voltage bushing.

Description

technical field [0001] The invention relates to a high-voltage bushing and high-voltage electrical equipment using the high-voltage bushing. Background technique [0002] The high-voltage bushing mainly has a single-layer shielding bobbin structure and a double-layer shielding bobbin structure. For example, the Chinese patent document with the application publication number CN105811294A discloses an outlet bushing structure, including a composite insulator and an inner cavity of the composite insulator. For high-voltage conductors, there are two shielding cylinders, namely the grounding shielding cylinder and the intermediate shielding cylinder. The grounding shielding cylinder is connected to the flange, and the intermediate shielding cylinder is connected to the supporting insulator. The double-layer shielding structure formed by the intermediate shielding cylinder and the grounding shielding cylinder, The insulation margin of the outlet bushing is improved, but the bushin...
