| External insulation of power transmission equipment has a significant impact on the safety of the power grid. Power system widely used insulator, the surface contamination and moisture will seriously affect the electrical properties of insulators, endangering the safe operation of the grid. With the grid capacity, transmission voltage level is raised, particularly the gradual deterioration of the air environment, pollution flashover outside the insulated high-voltage power transmission equipment produced frequently contaminated, causing direct economic losses of nearly one hundred million yuan(. And under China’s rapid economic development, the electricity situation is very tense situation, brought a lot of social economic impact can not be measured, and pollution flashover very important part of our current range of production safety management, therefore, prevent and reduce pollution flashover the occurrence of great significance, the current power sector is also growing on the pollution flashover work input.With China’s rapid economic development, environmental pollution have become more prominent; grid expansion and development, but also to pollution flashover coverage increases, the safe operation of the power grid still bear the risk of a large area of flashover. Therefore, under the unified smart grid construction planning, the use of optical sensors to monitor external insulation equipment online filthy conditions, thus improving the overall external insulation level grid in order to effectively prevent the occurrence of large-scale pollution flashover, the ultimate realization of smart grid planning requirements.The system uses C / S and B / S structure combined database selected SQL Server 2000, to achieve a power transmission line inspection equipment contamination. Through the construction of power transmission equipment filthy line detection system system, using online monitoring replace artificial salt density monitoring points and automatically mapping real-time dynamic electronic polluted area map, enabling intelligent antifouling management; real-time monitoring of power transmission equipment salt density, master pollution Rules Sichuan power grid transmission and distribution equipment, and then guide the production department of the state power transmission equipment cleaning, in order to avoid excessive maintenance and inadequate maintenance of status; has been built by a saturated salt density is monitored the power transmission equipment adjustments insulation creepage distance to provide a scientific basis; saturated salt had taken secret delineated measured contamination level in Sichuan power grid, external insulation designed to provide the basis for new power transmission project; points through the construction of on-line monitoring and improvement, reduce operational risk officer Gordon bar. |
