Description

Technical Field

[0001] This utility model relates to the field of medium-voltage electrical equipment technology, and in particular to a rotatable support device for mounting busbars. Background Technology

[0002] In medium-voltage switchgear, insulators are used to fix the switchgear busbars. The insulators are fixed inside the switchgear through mounting holes. Different configurations inside the switchgear result in different installation angles for the busbars, which requires the insulators to change angles with the busbars. The original insulator mounting holes cannot meet the new angle requirements of the insulators, so new holes need to be drilled, which is time-consuming and labor-intensive. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide a rotatable support device for installing busbars, addressing the issue that conventional insulator mounting holes in medium-voltage switchgear cannot meet the new angle requirements of insulators, necessitating the time-consuming and labor-intensive process of re-drilling holes.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a rotatable support device for installing busbars, the innovation of which is: including a mounting bend plate, an insulator, an aluminum washer ring, a bushing and an aluminum connector;

[0005] The mounting bend is installed inside the medium-voltage switchgear. The mounting bend has a Z-shaped structure and two mounting holes on each of its two flanges. It is then installed on the medium-voltage switchgear with bolts. The surface of the mounting bend is connected to the insulator with bolts.

[0006] The insulator is a cylindrical structure cast from epoxy resin, and one end of the insulator is provided with a threaded hole for assembly with an aluminum connector.

[0007] The aluminum connector is assembled to the end of the insulator by connecting bolts, and one end of the aluminum connector has a stepped through hole that mates with the connecting bolts.

[0008] The aluminum washer ring is located at the end of the insulator, and the aluminum washer ring has a through hole to accommodate the connecting bolt; the connecting bolt passes through the stepped through hole on the aluminum connector and the threaded hole at the end of the insulator in sequence.

[0009] The bushing is nested on the connecting bolt, and the connecting bolt is placed in the stepped through hole of the aluminum connector.

[0010] Furthermore, washers and gaskets are provided at the connection between the connecting bolt and the stepped through hole.

[0011] Furthermore, an insert is provided at the end of the connection between the insulator and the mounting bend plate, and the insert is engaged with the mounting bend plate by bolts.

[0012] The advantages of this utility model are:

[0013] 1) In this utility model, after installation in the medium-voltage switchgear, the busbar can be installed by rotating the aluminum connector; unlike insulators installed at a fixed angle, the rotation angle is variable, so it can be used for different installation angles and has a wider range of applications; the axial movement of the connector of the insulator device can improve the installation accuracy.
