光传感器在绝缘子盐密测试中的应用

Application of Light Sensor in Insulator Salt Density Test

随着电网容量、输电电压等级的提高,特别是空气环境的进一步恶化,电网防污闪工作形势依然十分严峻。光传感器输变电设备盐密在线监测系统是一种实时、在线、科学、准确的盐密监测方法。通过传感器采集的污秽信息可以计算得出绝缘子表面的盐密值、灰密值。

With the improvement of grid capacity and transmission voltage level, especially the further deterioration of the air environment, the grid pollution flashover work still very grim. The online monitoring system of light sensor transmission and distribution equipment salt density is a real-time,online, scientific, accurate monitoring methods of salt density. Dirty information collected by sensors can be calculated to obtain the salt density and ash density value of the insulator surface.
