The pollution degree of an insulator refers to the pollution degree of a certain geographical area where the insulator is located. Line flash pollution will cause large-scale power outages and seriously affect the reliability of power supply.
In order to prevent pollution flashover accidents, it is necessary to make reliable monitoring and accurate judgment on the pollution degree of insulators, so as to provide a basis for the selection of insulation equipment and timely anti-pollution flashover measures. At present, the rough judgment and accuracy of pollution degree registration are not high. The problem has become an important factor restricting the effective implementation of anti-pollution flashover measures.
Pollution flashover of external insulation of power equipment is one of the difficult problems hindering the safe operation of power systems. The application of synthetic insulators and glass insulators has not fundamentally changed the importance of pollution flashover prevention in power systems. Rubbing, crawling, and rubbing are still the basic measures to prevent pollution flashovers in operating equipment. Knowing the pollution degree of external insulation in time is the scientific basis for taking timely measures to prevent pollution flashover.
In order to ensure the normal operation of the transmission line, the online monitoring system for the pollution degree of the insulator of the transmission line came into being.
The system can realize the full perception of the status data of the transmission line. It is composed of modules such as salt density, gray density, temperature and humidity, and uses the acquisition unit to obtain the safety monitoring data. The text message sends out an alarm prompt, and the power personnel can also check the pollution degree data of the insulator through the platform and mobile phone, etc., to determine the health status of the line.
