Problems solved by technology

In the current typical structural scheme of the State Grid Corporation of China, the cable branch gloves are all installed at the bottom of the cable room, the installation space is cramped, and the phase length of the cable terminal is insufficient. Especially for cables with large cross-sections, it is easy to cause stress on the cable terminal due to improper construction. Heat generated due to poor crimping with the bushing, resulting in material aging and accidents due to insulation failure

Abstract

The invention discloses a cable terminal assembly and a cable terminal abnormal heating monitoring system. The cable terminal assembly includes: an electrical connection improvement unit, which is arranged on the cable terminal head and is used to improve the electrical connection between the cable terminal and the casing of the cable room Method: The mechanical stress improvement unit is arranged at the intersection of the cable terminal and the wire entry hole, and is used to improve the mechanical stress of the cable as a whole and each branch cable. In the present invention, the cable branch gloves are placed outside the cable to ensure the length of the cable phase separation, the cable direction is guaranteed to be standardized through the cable arc guide groove, and the overall fixed position of the cable and the fixed position of the branch are added, which is beneficial to improve the problem of mechanical stress; the double hole structure design is used , in the form of surface contact, the electrical connection between the cable terminal and the cable room casing is improved, and the requirements for the construction technology level are reduced.

Description

technical field [0001] The invention relates to a cable terminal assembly and a cable terminal abnormal heating monitoring system, belonging to the technical field of power cables. Background technique [0002] At present, under the trend of increasingly compact power distribution main equipment such as ring main unit and switch cabinet, the size of its cable room is getting smaller and smaller. In the current typical structural scheme of the State Grid Corporation of China, the cable branch gloves are all installed at the bottom of the cable room, the installation space is cramped, and the phase length of the cable terminal is insufficient. Especially for cables with large cross-sections, it is easy to cause stress on the cable terminal due to improper construction. Poor crimping with the bushing will cause heat, resulting in material aging, and accidents due to insulation failure. [0003] The function of the cable terminal is to realize the connection between the cable a...
