Rapid connection device for high-voltage cable of GIS combination electrical appliance equipment

Abstract

The invention discloses a rapid connection device for a high-voltage cable of GIS combination electrical appliance equipment. The rapid connection device comprises a cable terminal cylinder and a cable, wherein the cable is laid along a cable trench, the cable is provided with a cable head, the cable head is inserted into the cable terminal cylinder from the bottom of the cable terminal cylinder,a cable terminal connection conductor is arranged in the cable terminal cylinder and is connected with the cable head, the rapid connection device is characterized in that the cable terminal cylindercomprises a vertical segment, an included angle segment and a circular arc transition segment, the vertical segment is perpendicular to ground, an included angle is formed between the ground and the included angle segment, the circular arc transition segment is connected with the vertical segment and the included angle segment, the cable head is arranged at the included angle segment, the cable terminal connection conductor is provided with an initial end and a tail end, the initial end is arranged in the vertical segment, and the tail end is arranged at the circular transition segment. By therapid connection device, the depth of the cable trench can be obviously reduced, and the effects of optimizing a power distribution device site, reducing building project, reducing construction workload, reducing construction period and facilitating running and maintenance are achieved.

Description

technical field [0001] The invention relates to electric power engineering technology, in particular to the installation technology of combined electric appliances and high-voltage cables. Background technique [0002] Combined electrical appliances and high-voltage cables are widely used in power systems, especially in the construction of urban power grids with voltage levels of 110kV and 220kV, due to their small footprint, small size, high reliability, and almost no need for maintenance. Cable terminals are mostly arranged in a vertical structure. According to the provisions of the "Code for Design of Electric Power Engineering Cables" (GB50217-2007), "the cable shall meet the requirements of the allowable bending radius of the cable in any laying method and all path conditions where the cable changes up, down, left, and right. ", "The allowable bending radius of the cable should meet the requirements of the cable insulation and its structural characteristics. For the sel...

AI Technical Summary

Problems solved by technology

In order to meet the requirements of the cable bending radius, the depth of the cable trench needs to be less than 2.5 to 3 meters, which has the disadvantages of hi
