Abstract

The invention relates to a laser pollution sensor, comprising a laser device, a beam splitter, two fiber bundles, fibers, quartz rods, two photoelectric converters and four optical connectors. The two ends of each fiber bundle are fixedly connected with the optical connector. The laser generated by the laser device enters the beam splitter. One splitting end of the beam splitter is connected with the quartz rod via one fiber bundle. The quartz rod is connected with one photoelectric converter via the other fiber bundle. The other splitting end of the beam splitter is connected with the other photoelectric converter via a fiber. The laser pollution sensor is applied to the automatic online monitoring of the pollution degree of the insulator surface of the high-voltage power transmission line, can effectively solve the imprecision problem of the conventional manual measurement and the like, and supply important data to the design, maintenance and security management of the high-voltage power transmission line.

Description

technical field [0001] The invention relates to a laser pollution sensor, which can be used for automatic on-line monitoring of air pollution degree (salt pollution and dust pollution) on the surface of objects. Background technique [0002] The traditional method of measuring the pollution degree of high-voltage transmission line insulators is to cut off the power of the transmission line or substation where the tested product is located, then wash off all the dirt on the surface of the tested product and dissolve it in a certain amount of distilled water, and measure the conductivity of the solution , and then converted into equivalent pollution degree. According to the new enterprise standard promulgated by the State Grid Corporation of China at the end of 2006: Q / GDW 152-2006 "<Power System Pollution Area Classification and External Insulation Selection Standard", it is pointed out that the division of the pollution area distribution map has changed from simply consid...
