Abstract

The invention discloses an online monitoring system for partial discharge of a high-voltage cable. The online monitoring system involves a terminal acquisition module, a network transmission module, adata management module and a user visual module, wherein the terminal acquisition module is connected with the network transmission module, the network transmission module is connected with the datamanagement module, and the data management module is connected with the user visual module. According to the online monitoring system, through cooperation between a terminal acquisition module sensorgroup and a distributed partial discharge acquisition terminal, efficient acquisition of data is completed, and the fault detection speed is accelerated; through the use of a wireless transmission technology of the network transmission module, the data transmission rate is greatly improved; through application of a central server of the user visual module, online monitoring is realized, so that adetection interface is more user-friendly; and a WeChat applet is developed at the mobile terminal of the user visual module, so that high sharing of information is realized.

Description

technical field [0001] The invention relates to the field of high-voltage cable fault monitoring, and more particularly, relates to an on-line monitoring system for partial discharge of high-voltage cables. Background technique [0002] With the development of urbanization, high-voltage cables have been widely used on transmission lines. However, due to its own defects, often in harsh and complex environments, as well as external damage and loss caused by construction and installation, high-voltage cables often have insulation defects, which cause partial discharges, resulting in a service life of high-voltage cables that is much lower than the theoretical life. . It is not uncommon for large-scale power outages in the power grid due to cable failures every year, which seriously threatens the stability of power system operation and greatly damages the national economy. [0003] At present, most of the monitoring and diagnosis of partial discharge in my country's high-volta...
