Abstract

The invention discloses a cable partial discharge analysis method, device, a storage medium and a processor. The method comprises steps: multiple target values are obtained; based on the multiple target values, multiple target ratio values are obtained; three-dimensional space is constructed based on the multiple target ratio values; based on the three-dimensional space, a first trajectory and a second trajectory are obtained, wherein the first trajectory is used for indicating the change trajectory of the multiple target ratio values when the cable is in a first state, and the second trajectory is used for indicating the change trajectory of the multiple target ratio values when the cable is in a second state; and based on the first trajectory and the second trajectory, a cable analysis report is obtained, wherein the analysis report at least comprises cable partial discharge fault diagnosis data and cable danger degree analysis data. Thus, the problem that when the cable is detectedby a related technology, the traditional offline or online diagnosis method can not timely and fully characterize the local defect or aging state of the cable can be solved.

Description

technical field [0001] The present application relates to the field of cable communication, in particular, to an analysis method and device, a storage medium and a processor for cable partial discharge. Background technique [0002] In related technologies, with the continuous improvement of the level of industrialization and urbanization in our country, the demand for power has also increased sharply, and the requirements for the safety and stability of the power system have also become higher and higher. Because of the characteristics of easy installation, high electrical strength and small dielectric loss, power cables can effectively solve the problems of urban power consumption aggregation effect and excessive land occupation of overhead lines. It has been rapidly promoted in the power grid, and power cables have developed into important equipment for power transmission at various voltage levels. They play an indispensable role in the safety of power loads and reliable ...
