Smart Online Monitoring System For Insulator Surface Measuring Contamination

Quick Detail:Electricity Maintenance Transmission line Device for measuring contamination of insulator surface

Application Background

The problem of external insulation, especially pollution flashover, has always been one of the important issues that plagued the development of China's power system. The key element to prevent pollution flashover accidents is that the power operation department can timely and accurately grasp the external insulation status of the operating insulator string so that measures can be taken in time before a pollution flashover accident may occur. This is also a requirement for smart grid and line condition maintenance.

Product Principle

The general idea of the pollution monitoring and early warning system is: first, by using reliable online monitoring technology, grasp the pollution status of the main grid in key polluted areas in each region in real time and accurately; and based on the real-time monitoring, comprehensively consider the impact of environmental meteorology and other factors , Modeling the relationship between temperature, humidity, leakage current, and pollution flashover voltage, combined with weather forecast, analysis and prediction of pollution flashover risk of the lines in the monitoring area, to form a set of power grid pollution early warning technology with engineering application standards.
The system adopts a distributed data acquisition integrated system in design. The main part includes a field monitoring terminal, a data processing unit, and a background monitoring and analysis system. The system functions are divided into field data collection, 3G communication transmission, analysis calculation, and evaluation and decision-making. Work steps. as the picture shows.
