Description

Cable terminal temperature detection system

Technical Field

The utility model relates to an electric power field, more specifically relates to a cable termination temperature detecting system.

Background

At present, in a power system, a main failure of the cable terminal is that the insulation layer is aged to generate a partial discharge phenomenon, which may cause a continuous temperature rise to cause serious heat generation of the cable terminal. If the cable head is in a high-temperature state for a long time, a power system fault can be caused, and serious economic loss is caused.

However, because of too many cable terminals in the power system and a low probability of failure of the cable terminals, at present, there is no complete system for automatically detecting whether the cable terminals are in a heating state, and when a failure occurs in the power system, the operation and maintenance personnel finally check the cable terminal failure through careful patrol and inspection, and this manual inspection method not only increases the time for failure and power failure, but also greatly affects the reliability of power supply, and consumes a large amount of labor cost and time cost.
