Description

Technical Field

[0001] The invention relates to the technical field of salt density and ash density testing, in particular to a portable real-time measurement device for the contamination degree of external insulation equipment. Background Art

[0002] The optical sensor measures salt density based on the light field distribution theory and light energy loss mechanism in dielectric optical waveguides. The low-loss quartz rod placed in the atmosphere is a multi-mode dielectric optical waveguide with the rod as the core and the atmosphere as the cladding. When there is no pollution on the quartz rod, the fundamental mode and higher-order modes in the optical waveguide transmit the light energy together. Most of the light energy is transmitted in the core of the optical waveguide, but a small part of the light energy will be transmitted along the cladding at the core-cladding interface. The light loss during the light wave transmission process is very small. When there is pollution on the quartz glass rod, the pollution changes the transmission conditions of the higher-order mode and the fundamental mode; at the same time, the absorption and scattering of light energy by the pollution particles will cause light energy loss; the amount of salt on the sensor surface can be calculated by detecting the light energy parameters.

[0003] Since the sensor and the insulator string are in the same environment, the salt density value on the insulator surface can be obtained by calculation;

[0004] The laser salt density and ash density tester is a device used to detect the surface ash density (NSDD) and salt density (ESDD) of insulators. It is mainly used to prevent pollution flashover accidents in power systems. It adopts the principle of laser frequency conversion transmission and can directly test the ash density without filtering, drying and weighing. It can also measure the salt density at the same time, simplifying the detection process. The instrument has built-in test containers and precision electrodes to achieve integrated testing of salt density and ash density. It has the characteristics of touch screen operation, fully automatic testing, portable design, intelligent data analysis and multiple output modes. It is suitable for inspection sites and laboratories. When detecting ash density and salt density, the laser salt density and ash density tester usually requires manual sampling. The sampled samples are not uniform in pollutants and salt, which affects the test efficiency and test results. Therefore, a portable real-time measurement device for the degree of contamination of external insulation equipment is proposed to solve the above problems. Summary of the invention
