A new type of on-line measurement system for salt density on the insulator surface of power transmission and transformation equipment

Abstract

The invention provides a novel online measurement system for salt deposit density of an insulator surface of electric transmission and transformation equipment. The novel online measurement system comprises a bare fiber, single mode fibers, optical flange seats and a vehicle-mounted measuring instrument, wherein the bare fiber is mounted on the insulator surface of the electric transmission and transformation equipment; the single mode fibers which are integrated with the bare fiber are arranged at the two ends of the bare fiber; one optical flange seat is connected with the lower end part of each single mode fiber at each end of the bare fiber; the vehicle-mounted measuring instrument is internally provided with a single vertical mode laser device and a photoelectric converter with an amplification function; the photoelectric converter with the amplification function is connected with a collector and the collector is connected with a computer. The novel online measurement system for the salt deposit density of the insulator surface of the electric transmission and transformation equipment has the beneficial effects that the system is small in volume, is passive and has no electronic elements; a discharging end is not caused and the electromagnetism distribution of a power transmission conductor is not influenced; the system resists electromagnetic interference and is low in cost; the measurement density is easy to increase and a distribution type measurement manner is formed; the online measurement system for the salt deposit density of the insulator of the electric transmission and transformation equipment is established and a power grid pollution flashover accident caused by environmental pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of sensor measurement and monitoring, and in particular relates to a novel on-line measurement system for salt density on the surface of insulators of power transmission and transformation equipment. Background technique [0002] 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. . Pollution flashover accidents of electrical equipment occur frequently in the national power grid, especially the large-scale pollution flashover in the national power grid has caused huge losses to power production. Preventing and reducing the occurrence of pollution flashover accidents i...
