Abstract

The invention discloses a cable dielectric loss detection method, device, storage medium and processor. Wherein, the method includes: obtaining the current value 1 measured by the current sensor 1 on the cable to be tested, and the current value 2 measured by the current sensor 2, wherein the current sensor 1 is installed on the cross-connection grounding of the cable to be tested The current sensor 2 is installed on the lead-out line below the connection point of any two phases in the cross-connected grounding box on the cable to be tested; according to the current value 1 and the current value 2, determine the cable to be tested media loss condition. The invention solves the technical problem that the cable insulation cannot be effectively monitored in the related art.

Description

technical field [0001] The invention relates to the field of cables, in particular to a method, device, storage medium and processor for detecting dielectric loss of cables. Background technique [0002] Compared with overhead lines, power cable lines have the following significant advantages: 1) It is not easily affected by natural weather conditions and the surrounding environment, and has high power supply reliability; 2) The insulation distance between lines is small and occupies less land; 3) It does not occupy the ground, Space, the same underground cable channel, can accommodate multiple circuits. Therefore, power cable lines are more and more commonly used in super-large cities with tight land resources. Among various types of power cables, cross-linked polyethylene (XLPE) cables are the most widely used due to their high dielectric strength, small dielectric loss coefficient, easy laying, and simple operation and maintenance. universal. [0003] In recent decades...
