Closed cable temperature information processing method

Abstract

The invention relates to a closed cable temperature information processing method, which includes the following steps: firstly, a back-stage management server reads cable position information and temperature information for a site data acquisition unit in a real time manner through a communication network; secondly, according to the cable position information, the back-stage management server looks up theoretical temperature information corresponding to the cable position information from a database server, compares the actual temperature information with the theoretical temperature information, judging whether the difference value of the actual temperature information and the theoretical temperature information surpasses the set threshold value, the step 3 is performed if the difference value surpasses the set threshold value, and the step 1 is performed if the difference value is lower than the set threshold value; thirdly, the back-stage management server gives an alarm, and sends the alarming information and the cable position information to a remote terminal, the corresponding cable is powered off immediately from the remote terminal, and then the cable position information is sent to a maintenance terminal; fourthly, detection for the cable at a corresponding position is performed at the maintenance terminal, so that debugging for the fault message is timely realized and the cable is powered on. Compared with the prior art, the closed cable temperature information processing method has the advantages of high monitoring efficiency and the like.

Description

Technical field [0001] The invention relates to a cable temperature monitoring technology, in particular to a closed cable temperature information processing method. Background technique [0002] Online temperature monitoring has been widely used in various fields. For the power industry, real-time online temperature monitoring of cables and related equipment is an important measure to ensure the safe and stable operation of the power grid. However, little work has been done in this area. [0003] Cable lines are now gradually replacing overhead lines and become the main body of urban power grids. Therefore, the network structure is becoming more and more complex, with many joints and branches. These cables are easy to form heating points where they are connected and tapped. When it is larger, it is easy to overheat and cause equipment damage, or even power outages. Therefore, for the safe and stable operation of the power grid, online temperature monitoring at these key points i...

Problems solved by technology

[0004] At present, the operating temperature of each contact in the cable joint, branch box and ring network cabinet cannot be known in real time. Generally, it is necessary to use an infrared thermal imager to check whether the operating temperature is normal during inspection.

In view of the importance of the cable line and its ancillary equipment, the power company will regularly inspect the equipment on the line. This method generally has defects such as low work efficiency and low monitoring accuracy.
