Description

technical field [0001] The invention relates to the technical field of intelligent insulator monitoring, in particular to an insulator intelligent wide-area state detection system and a state identification method. Background technique [0002] The security and stability of the power transmission network is an important guarantee for the sustainable development of the national power system. In the power system, the insulator is an important equipment for supporting and insulating the cable. It can secure the high-voltage cable while ensuring the creepage distance between the high-voltage cable and the tower. However, during the online operation of insulators, due to factors such as material aging, environmental contamination, and external collisions, local cracking, resistance reduction, and flashover breakdown may occur, resulting in performance loss or even complete failure. The performance loss and failure of insulators will seriously endanger the security of the transmi...

Problems solved by technology

[0007] 1. There are a large number of insulators and they are widely distributed. If tens of thousands of insulator detection equipment are directly connected to the grid background for communication, it will not only take up a large amount of communication bandwidth, but also easily lead to communication congestion in the entire system, which will lead to energy consumption and time. The increase in consumption and the huge data processing pressure on the background of the power grid require the ability to process massive amounts of data at the same time, making it difficult for the above methods to meet the requirements of wide-area "intelligence", "wide-area" and effectiveness

[0008] 2. Insulators are usually in a special and changeable open-air working environment, and the physical information captured by the detection equipment is easily disturbed by factors such as natural climate, flying organisms, and even equipment failures

The above-mentioned insulator state detection method is realized only by simple logical judgment of the physical information of a single insulator at a single moment. If there is an error or failure in the detection equipment, accurate results cannot be obtained, so it is very easy to miss or misjudgment.
