Description

technical field [0001] The invention relates to the field of safety detection of high-voltage power transmission equipment, in particular to a method and system for corona monitoring of high-voltage power grids based on the Internet of Things. Background technique [0002] Corona discharge refers to the self-sustained discharge phenomenon that occurs when there are many local ionization and excitation processes on the surface of a charged body in a gas or liquid medium, but there is no breakdown or conduction between electrodes. In very high areas, such as corona discharge of transmission lines, high-voltage electrical appliances, insulators, etc. in the power field. Corona consumes electrical energy, and the pulsed electromagnetic waves generated during corona discharge will interfere with radio and high-frequency communications; corona will also corrode the surface of the wire, thereby reducing the service life of the wire. [0003] Factors such as arc, corona and partial...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the above-mentioned defects in the prior art, the present invention provides a method and system for corona monitoring of high-voltage power grid based on the Internet of Things. By establishing a monitoring system on the high-voltage power grid, the equipment failure caused by corona discharge The power grid accident has the function of early warning, which solves the shortcomings of the current high-voltage power grid that requires manual on-site inspections, which not only makes the management of the high-voltage power grid labor-intensive, but also makes it difficult to detect corona troubleshooting in time
