Cable inlet device

Abstract

The invention discloses a cable inlet device which comprises a box body, a sliding support structure is arranged in the box body, a terminal base is installed on the sliding support structure, the terminal base is connected with a sag adjusting structure, and the sag adjusting structure is connected with the sliding support structure. The sliding support structure comprises supporting guide railswhich are symmetrically arranged on the box body; a guide slide rail is arranged on the box body under the support guide rail; a middle bearing rod is erected between the two supporting guide rails; afixed base for mounting the terminal base is arranged in the center of the middle bearing rod; edge bearing rods are erected between the two sides of the fixed base and the two guide sliding rails correspondingly. The edge bearing rod is provided with a sliding base used for installation of the terminal seat, the edge bearing rod is provided with the sag adjusting structure used for driving the sliding base to move, the distance between the terminal seats is increased or decreased through the sliding support structure, and the tightening degree between the cable and the terminal seats is changed through the sag adjusting structure.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of transformers, and in particular to a cable inlet device. Background technique [0002] Substations play a pivotal role in the operation of the power grid. Conventional substations are fixed, and their construction, installation and commissioning take a long time to complete. In reality, substations may be damaged due to various natural or artificial factors, resulting in paralysis of the power grid. In order to restore the functions of substations as soon as possible, in the prior art, mobile substations are often used to replace conventional substations to restore power supply to meet industrial or daily needs. use electricity. [0003] Patent No. CN107634464A provides a mobile substation, which includes a high-voltage substation car and a medium-voltage distribution car as a mobile platform. The high-voltage substation car is equipped with 110kV high-voltage combined electric...
