All-insulated cable connector

Abstract

The invention discloses an all-insulated cable connector, comprising a connecting plug and a cabinet body fixing assembly located at one end of the connecting plug, wherein the connecting plug is an F-shaped connecting plug, the F-shaped connecting plug is fixed to a partition plate through the fixing assembly, the F-shaped connecting plug is connected with a conductive rod through a first connecting assembly, the F-shaped connecting plug is provided with a cavity for accommodating the conductive rod, and the first connecting assembly comprises a conversion connecting nut connected with the conductive rod and an elastic conductive plug arranged in the conversion connecting nut. According to the invention, the all-insulated cable connector ensures that connection resistance meets the requirements of current conduction capability and temperature rise and that the contact resistance and contact pressure meet the requirement of the temperature rise; and the all-insulated cable connector adapts to the power utilization requirements of urban economy and resident life, promotes the national comprehensive construction of an intelligent power grid distribution system, meets the cable connection power supply requirement of a voltage transformer of an all-insulated ring main unit and improves power supply reliability.

Description

technical field [0001] The patent of the present invention relates to a high-voltage cable connector, especially a fully insulated cable connector, in particular to a fully insulated cable connector applied to a fully insulated ring network cabinet. Background technique [0002] In the current known technology, the voltage transformer of the 12kV fully insulated ring network cabinet in the power grid is carried out with ordinary T-shaped cable connectors. Due to the influence of the size of the fully insulated ring network cabinet, it is often unable to meet the high voltage due to the radius of the return bend. The cable bending requirement has repeatedly caused voltage transformers to burn out insulation accidents in the power supply system, seriously affecting the safety of the power supply system and affecting the safety and reliability of the power supply. [0003] Based on this, how to provide a dedicated fully insulated cable connector with good insulation strength, l...

AI Technical Summary

Problems solved by technology

[0004] In view of the problems in the prior art, the purpose of the present invention is to provide a fully insulated cable connector and the application technology of the fully insulated cable connector on the fully insulated ring network cabinet, so as to solve the problem of the existing installation in the fully insulated ring network cabinet. The voltage transformers are connected by ordinary T-shaped cable connectors. Due to the influence of the size of the fully insulated ring network cabinet, the bending radius of the 12kV silicone rubber insulated cable cannot meet the requirement of 4 times the cable diameter, and the voltage mutual inductance has been caused many times in the 12kV power supply system. The burnout and insulation accident of the device has seriously affected the safety of the power supply system.
