AI Technical Summary

Technical Problem

The existing cable docking structure needs to be extruded during installation, resulting in uneven electric field distribution and excessive local electrical stress, which affects the stability and safety of the structure.

Method used

A cable docking structure for power engineering circuits is designed, including docking cylinders and installation mechanisms. The installation mechanism includes a placement cylinder, a limiting mechanism and an adjustment mechanism. Through the cooperation of the ring plate and the winding spring, the cable joint is evenly squeezed to ensure the even distribution of electrical stress.

Benefits of technology

By uniformly extruding the cable joint, the problem of uneven electric field distribution is solved, the uniformity of electrical stress at the cable connection is improved, and the stability and safety of the docking structure are enhanced.

Abstract

The invention discloses a line design cable butt joint structure for electric power engineering, and relates to the technical field of cable butt joint, the line design cable butt joint structure comprises a butt joint cylinder, the two ends of the butt joint cylinder are provided with mounting mechanisms for placing inserted cables, each mounting mechanism comprises a placing cylinder, and the placing cylinders are symmetrically installed at the two ends of the butt joint cylinder; a limiting mechanism for fixedly limiting movement of the cable is arranged on the inner wall of the placing cylinder, an adjusting mechanism for adjusting the distance between cable joints is arranged on the outer wall, close to the placing cylinder, of the butt joint cylinder, the cable is inserted into the placing cylinder, the annular plate wraps the part, needing to be connected, of the cable, and the cable is pulled to be extruded by the annular plate; and the extrusion stress at the cable joint is more uniform, so that the electric stress distribution at the cable joint is more uniform, and overhigh local electric stress caused by non-uniform electric field distribution is avoided.
