Development of Optical Salt Detection Monitoring Systems in Electrical Facilities
Abstract
Salt damage refers to a phenomenon in which chlorides penetrate into the interior of electrical facilities and corrode them, thereby damaging switchboards installed close to the seashore. When an outdoor switchboard, etc. is exposed for a long period of time in a marine environment, cracks occur due to corrosion expansion due to corrosion of iron and the like due to the influence of salt contained in seawater and its expansion pressure. As a result, the durability of the electrical equipment is greatly deteriorated due to self-deterioration, and in severe cases, the equipment is destroyed. However, there are not many research and analysis data on power facilities such as outdoor switchboards that have been damaged by salt, and research on measures to prevent salt damage is not active in Korea. In addition, it is judged that there is a need for technology development and suitable implementation measures for this situation due to insufficient verification of the salt damage monitoring method and applicability that are used in some cases.
In this paper, we develop an optical salt detection and monitoring system that can perform efficient response and diagnosis by measuring and monitoring salt particles to prevent insulation or unexpected conduction of equipment inside outdoor electrical facilities due to intake air containing salt. Optical sensing technology is stable because it is not affected by strong current, radio waves, and noise due to the internal characteristics of existing electronic sensors. It measures and monitors salt particles in the air in real time, preventing performance degradation and equipment damage caused by salt. The salinity detection system using the optical method includes a salinity detection unit, a salinity detection device including a salinity detection module and a particle quantity identification module in the air, a salinity detection device software, and a salinity detection monitoring server and App. The developed system tested the salinity sensing response speed, salinity sensing accuracy rate, and salinity sensing state event alarm display accuracy. The developed system is expected to be useful for preventing salt damage in outdoor electrical facilities.
