Humidity Control System Design Of House-style Switching Station Environment

With the continuous progress and development of science and technology, more and more household appliances provide more high-quality, convenient services for people, from daily necessary lighting source to washing machine, vacuum cleaner of reducing the human labor intensity, and TV, computer of providing mankind spiritual and cultural needs, almost all of the common household facilities needed electricity to drive. It just reflects the influence of power in people's daily life. People for the power supply reliability and uninterrupted power are in an increasingly demand. According to Jilin Electric Power Co., Ltd. operation analysis report can be found in the Eleventh Five-Year Plan period, the power supply reliability in Jilin area residents from 98.903% up to 99.323%. Many experts say, modern society is addicted to power dependency. Affected by the regional climate, and position environment of many newly built substations, switching station, ring network cabinet and other factors, many substations, switching station, ring network cabinet's internal environmental humidity is relatively too high. More than standard humidity of equipment operation will cause equipment insulation degree to reduce, corona discharge phenomenon intensifies, and these phenomena will lead to power equipment accidents. It has become a major problem of threatening the safety of power system operating situation. Currently, more commonly used methods in moisture discharge both in domestic and foreign generally choose dehumidifier air- conditioning, air exchange and low humidity and professional dehumidifier to achieve, but the device operating costs are too high, there is no comprehensive system in the electric power facilities of proposed energy saving, fast and accurate moisture discharge mode. To solve this problem, combined with the MCU and the program design, and give full consideration to equipment installation site operating conditions, the cost and the feasibility of design scheme, given a set of house-style switching station equipment of humidity control system design to solve the problem.Considering the installation of equipment not only has the newly-built house-style switching station, and has old house-style switching stations, the house-style switching station equipment of humidity control system central processing chip, external expansion requires a relatively high ratio of performance to price.In addition, in the design process, because there is nobody in the house-style switching station, system parameter setting and operation and maintenance to be simple and easy to operate, and have a bad environment alarm function.In this paper, the house-style switching station equipment of humidity control system central processing chip, external expansion of the reasons for selection, the cost performance and design procedures were stated specifically. At the same time, it will compare the status of the equipment operation before and after system installation as well as the data of humidity measurement, contrast the changes before and after the installation of equipment operating environment. Finally, on its feasibility were elaborated.
