Problems solved by technology

Cracks or even ruptures in the insulator will directly lead to a decrease in the insulation capacity of the insulator and seriously affect the safe operation of the power system.
The traditional maintenance methods of insulators are mainly based on regular maintenance and cleaning, which cannot send out alarm information in time before insulators have potential safety hazards

Abstract

The invention belongs to the technical field of high-voltage electric appliance protection and particularly to a high-voltage insulator online monitoring system and method. The monitoring system comprises monitoring devices and a remote data center; each monitoring device comprises a data collection module, a GPS positioning module, a control module and a GSM communication module; the remote datacenter comprises a data reception unit and a console; and the console comprises a controller, a memory and a display device and is stalled with a parallel computing system. The control method of the monitoring system comprises the steps of 1) sending state information and position information of each insulator to the remote data center by each monitoring device; 2) storing and displaying the stateinformation and the position information of each insulator by the remote data center; 3) obtaining filth degree information and crack degree information on the surface of each insulator by the remotedata center through the parallel computing system to serve as a computing result and obtaining and displaying an alarm notification based on the computing result.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electrical protection, and in particular relates to an on-line monitoring system and method for high-voltage insulators. Background technique [0002] With the rapid growth of the grid scale and the increasingly complex grid structure, users have stricter requirements for the stable operation of the grid and the stability of power transmission. When the power system is covered with ice in winter, the insulators are prone to cracks or even ruptures; in wet weather or with a large amount of dust attached to the insulators, sometimes wet flashover and pollution flashover accidents will occur. These accidents will bring huge losses to the power grid. [0003] Pollution flashover refers to the electric ceramic surface of power equipment, which is polluted by conductive substances such as solid, liquid or gas. When it encounters fog or drizzle, the leakage current becomes larger and partial discha...
