The invention discloses an on-line monitoring system for the non-soluble deposit density of an insulator of a power transmission line. The on-line monitoring system comprises a control main board, wherein an analogue camera, a power supply control circuit, a GPRS module, a 485 interface, a debugging serial port, a humidity sensor and an illumination intensity sensor are respectively connected to the control main board; the GPRS module is connected with a monitoring center in a wireless manner. The invention further discloses a monitoring method of the on-line monitoring system. According to the monitoring method, a photo of a collected foul insulator is subjected to image algorithm analysis by virtue of an image analysis algorithm, and an accurate non-soluble deposit density value of the surface of the insulator can be obtained. According to the on-line monitoring system and the monitoring method, the non-soluble deposit density value having the important influence on insulation is obtained.
Description
technical field [0001] The invention belongs to the technical field of power transmission and transformation equipment monitoring, and relates to an on-line monitoring system for equivalent ash density of insulators in transmission lines, and also relates to a monitoring method for the on-line monitoring system for equivalent ash density of insulators in transmission lines. Background technique [0002] In recent years, with the rapid development of my country's economy, industrial pollutants have been increasing, and air pollution has become increasingly serious. The surface of insulators of power transmission and transformation equipment is easily affected by environmental pollutants in the installation area, so that when the pollutants accumulated on the surface of insulators get wet, it will cause insulation breakdown flashover, and insulation flashover may cause accidents and affect the reliability of power transmission and transformation equipment. . On the basis of s...
