Online monitoring system for state of insulator contamination

Abstract

The invention discloses an online monitoring system for the state of an insulator contamination. The monitoring system comprises a plurality of online monitoring devices for the state of the insulator contamination, an insulator monitoring base station, a W master station computer, a plurality of Internet user terminals and a plurality of mobile user terminals, wherein the online monitoring devices are mounted on an electric power pylon. Through the online state monitoring devices for the insulator contamination, the system monitors the density of contamination salt on the surface of an insulator and the leaked electric current of the insulator in a real-time manner to obtain the state of contamination on the surface of the insulator and give out a warning message for assisting an operation department in effectively cleaning the insulator, so that safety accidents caused by the contamination on the surface of the insulator are avoided.

Description

technical field [0001] The invention relates to the technical field of devices for measuring electrical variables, in particular to an on-line monitoring system for insulator dirt status. Background technique [0002] In recent years, the operation and management personnel of domestic and foreign electric power departments have been looking for effective solutions to measure the natural pollution of transmission line insulators. Various technologies have been tried on the on-line detection methods of insulators, and many products have been developed and put into the market. These products generally have physicochemical, electrical synthesis methods. After years of laboratory and field measurement research, the power measurement method has been developed rapidly. [0003] This device is manufactured by real-time and online detection of the electrical parameter changes of the insulator during operation, and the measurement results are relatively close to the operation mechani...

Problems solved by technology

But it also has its disadvantages: ①The quartz rod used for measurement is unevenly polluted up and down; ②Because the insulator fouling mainly includes conductive substances (salt dense) and non-conductive substances (gray dense), in practice these two main substances are The messy mixed substances cannot be separated. From the principle of geometric optics, it is difficult to separate the two main substances. In addition, there are some conductive substances in the atmospheric moisture, especially in thermal power plants and steel plants. Such phenomena are more serious in areas near pollution sources such as smelters and smelters, and the existence of such substances in ...
