AI Technical Summary

Technical Problem

Existing GIS cable silos are difficult to effectively limit the position of cables of different sizes, resulting in unstable cable positions within the silo and inability to reliably connect to the terminal head. Furthermore, traditional fixing methods are prone to loosening or size mismatch during long-term use, affecting the stability of power transmission.

Method used

The design incorporates an upper and lower housing, along with limiting and connecting components. Through the cooperation of limiting plates, sliding columns, and springs, it achieves multi-directional limiting of the cable. The design of the sliding plate and locking block enables quick assembly and disassembly, ensuring a secure cable connection.

Benefits of technology

It achieves stable positioning of cables of different sizes, improves the reliable connection between cables and terminals, enhances the applicability and flexibility of the cable compartment, and facilitates quick disassembly and maintenance.

Abstract

This utility model relates to the field of cable cassette technology and discloses a cable cassette for GIS, including an upper shell and a lower shell, which are fitted together. A protective shell is fixedly connected to one side of the lower shell. A cable conduit is disposed inside the lower shell, and a terminal head is disposed inside the lower shell. The cable conduit is located inside the protective shell, and a sealing ring is disposed on the outer wall of the protective shell. Limiting components are disposed inside both the protective shell and the cable conduit. A connecting component is disposed at the bottom of the lower shell, and the limiting components include multiple limiting plates. In this utility model, by inserting the cable into the protective shell and the cable conduit, the cable squeezes the arc-shaped plate, causing the limiting plate to overcome the spring force and slide along the sliding column within the protective shell and the cable conduit. The arc-shaped plates on the multiple limiting plates limit the cable from different directions, achieving effective limiting protection for the cable and ensuring that the cable is in a centered and stable position.
