Embodiment Construction

[0019] See attached figure 1 . attached figure 1 It is a schematic diagram of the front view of the present invention, from figure 1 It can be seen that the casing 1 of the present invention has a corrugated appearance.

[0020] See attached figure 2 . attached figure 2 is a schematic top view of the present invention, from figure 2 It can be seen that the shape of the wall bushing casing 1 is square, and there is a busbar perforation 2 in the center of the wall bushing, as well as a slope structure 5 integrated with the casing 1. The screw hole is 4-1, also see the direction of the A-A sectional view.

[0021] See attached image 3 . attached image 3 It is a schematic diagram of the present invention looking up, from image 3 You can see the busbar perforation 2 in the center of the wall bushing, and the wall bushings on the four corners are conventionally installed with fixed nuts.

[0022] See attached Figure 4 . attached Figure 4 is attached figure 2...

Abstract

The invention discloses a high pressure self-locking wall bushing comprising a wall bushing casing (1), a bus perforation (2), a bus (3), a screw (4), inclined structures (5) integrated with the casing (1) respectively arranged on the left and right sides of the bus perforation (2) in the casing (1), pressing members (6) having the same inclined plane with the left and right inclined structures (5) arranged on the inclined structures (5), screw perforations (4-1) and nut copper inserts (7) arranged in the two inclined structures (5) combining with the pressing members (6) through the screw (4) and fixed on the planes of the two inclined structures (5). The wall bushing of the invention increases self-locking function, which can conveniently lock the bus firmly, solve the technical problem of dynamic stability better, ensure that the switchgear under 40.5kV operates more safely and reliably and suit for the occasions on which high voltage live bus is needed cross such as between the cases on the high voltage switchgear, the incoming lines and outgoing lines of the high voltage switchgear and each small isolated cabinets in the cases, especially for the switchgear electrical equipment towards miniaturization trend.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and in particular relates to the improved design and manufacture of an indoor high-voltage wall-piercing bushing. Background technique [0002] Indoor high-voltage wall-piercing bushings are insulating support components, widely used in power systems, factories and mines, and indoor complete sets of switchgear with a voltage level of 40.5kV and below, such as high-voltage switchgear single-cabinet combination cabinets, high-voltage High-voltage through-wall bushings are used in places where the incoming and outgoing lines of the switchgear and between the isolation cells in the cabinet need to pass through the high-voltage live busbars. [0003] In the high-voltage cabinet, the three-phase live busbar often flows a strong current of hundreds to thousands of amperes, especially the short-circuit current of tens of thousands of amperes during a fault. Due to the limitation of the space i...
