Abstract

The invention relates to a temperature early warning method of a cable joint, and belongs to the field of cable fault monitoring. The temperature early warning method of the cable joint includes the following steps: step one: a monitoring node collects temperature value at the cable joint and transmits to an upper computer; step two: the upper computer processes and analyzes the temperature data transmitted by the monitoring node; if the temperature data value received by the system upper machine is higher than the preset threshold, the system upper machine sends a command to give an alarm. Through monitoring the temperature of the cable joint, the temperature early warning method of the cable joint can prevent the cable joint from fault and influence on cable power transmission due to the excess temperature.

Description

technical field [0001] The invention belongs to the field of cable fault monitoring, and in particular relates to a cable joint temperature early warning method. Background technique [0002] At present, the fault caused by the power cable is the main factor affecting the normal power supply, and the main reason for the cable fault is the production quality of the cable. However, when a power cable fails, a large part of the reason is that the cable will generate a high temperature during the long-term operation and supply of electricity. As the temperature of the power cable increases, the probability of failure of the power cable will increase. After a lot of investigations, it was found that the location of the power cable failure is in most cases at the cable joint. Since there is no very effective power cable temperature monitoring device at present, the probability of cable accidents will increase accordingly. Once a cable accident occurs, it will cause very serious ...
