Abstract

The invention discloses a cable dielectric loss detection method and device, a storage medium and a processor. The method comprises the following steps: obtaining a current value 1 measured by a current sensor 1 on the to-be-measured cable, and obtaining a current value 2 measured by a current sensor 2, wherein the current sensor 1 is installed on a common grounding wire of a cross interconnectiongrounding box and a direct grounding box on a cable to be measured, and the current sensor 2 is installed on a leading-out wire below a connection point of any two phases in the cross interconnectiongrounding box on the cable to be measured; and determining the dielectric loss condition of the to-be-measured cable according to the current value 1 and the current value 2. According to the invention, the technical problem that cable insulation cannot be effectively monitored in the prior art is solved.

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...
