Abstract
Description
Technical Field
[0001] This utility model relates to the field of switchgear technology, and in particular to a current transformer mounting mechanism. Background Technology
[0002] Currently, the installation process for current transformers in indoor armored withdrawable AC metal-enclosed switchgear involves installing a horizontal beam on the vertical beam of the rear panel of the cabinet, with the current transformer vertically fixed to the beam. The primary busbar is led from inside the busbar cabinet to the current transformer and then connected to the grounding switch, completing the installation of the primary equipment. However, this installation method has the following drawbacks: During installation, the current transformer is installed below the partition of the busbar compartment, causing mutual interference between the current transformer and the cables in the busbar compartment. Consequently, when replacing the current transformer, the cabinet needs to be de-energized, resulting in a power outage for the entire station and affecting operation. Utility Model Content

[0038] A threaded hole is provided at the bottom end of the mounting plate 201. The threaded hole is used for mounting bolt 5.
[0039] A locking element is provided at the top of the mounting plate 201. The locking element is used for mounting the mounting plate 201 and the mounting block 6.
[0040] Furthermore, the cabinet side panel 1 is the side panel of the existing indoor armored withdrawable AC metal-enclosed switchgear. Two cabinet side panels 1 are symmetrically arranged and are made of 2mm thick aluminum-zinc coated plate. The current transformer device 3 is the existing current sensor. The connecting busbar 4 is the existing cable terminal connection busbar. The connecting busbar 4 is fixed to the current transformer device 3 by bolts. The threads on the outer wall of the mounting bolt 5 and the threads on the inner wall of the threaded hole are engaged with each other. The current transformer device 3 is fixed to the mounting plate 201 by the mounting bolt 5. Four mounting blocks 6 are arranged, and the four mounting blocks 6 are symmetrically arranged in pairs on opposite sides of the cabinet side panels 1. The parts of the mounting blocks 6 that contact the cabinet side panels 1 are fixed by welding. The slot size of the mounting block 6 corresponds to the size of the locking block 202. Four locking parts are arranged, located at the four corners of the top of the mounting plate 201.
[0041] In embodiment two, this utility model provides a locking component, applied to the mounting mechanism in embodiment one. The locking component includes:
[0042] Locking block 202, the mounting block 6 has a slot for inserting locking block 202 on the side away from cabinet side panel 1;
[0043] Mounting box 203 has an internal cavity. One side of the inner wall of the cavity has a first round hole for inserting locking block 202, and the other side of the inner wall of the cavity has a second round hole. The bottom end of mounting box 203 is fixedly connected to the top end of mounting plate 201.
[0044] Pull rod 206 is inserted and connected to the second round hole.
[0045] The locking mechanism also includes:
[0046] The baffle 204 is fixedly connected to the locking block 202 and one end of the pull rod 206 on both sides, respectively.
[0047] Elastic block 205 is sleeved on the outer wall of tie rod 206.
[0048] The end of the elastic block 205 is provided with a circular through groove, and the pull rod 206 is inserted and connected to the circular through groove.
[0049] Furthermore, the bottom end of the mounting box 203 is welded and fixed to the top end of the mounting plate 201.
