基于表面响应面法的真空灭弧室电场分析.docVIP

摘 要 随着国民经济的快速发展，对能源的需求日益迫切，电力工业作为能源工业的主力受到极大的重视，这需要有更高的电压等级输电技术与之相适应，需要有电压等级更高，工作更加可靠，开断电流更大的断路器与之配套。而真空高压断路器以其真空火灾和爆炸的危险绝缘强度熄弧能力，触头行程短，操作功率小，整体积小、重量轻，使得真空断路器在箱式变电站、开关柜等装置中。With the development of national economy,the national need energy more and more urgent,the electrical industry is lay store by national government,so it need higher voltage level transmission technology with it,such as higher voltage level,working more steadily,disconnect larger short-circuit current.And that the vacuum breakers Vacuum and high vacuum interrupter, without the risk of fire and explosion, maintenance-free, and has a high insulation strength and ability to out-arc, contact trip short, power to operate small, whole small size, light weight, easy to achieve small , and makes vacuum circuit breaker in the box-type substation, switchgear and other devices are widely used, so we need study it more particular, advance its single breaking disconnecting capability, increase product reliability, lower manufacturing costs are the development tendency of today. Along with the development of computers performance and calculate technique advanced, in a variety of industries make good use of computer-aided design and computer-aided optimization for designing. At present, Response Surface Methodology(RSM) and Finite Element Numerical Analysis(FEM) are widely applied, and used in the calculation of the electric field and optimal design, so it reduce the time of revision and analysis. In this paper, we analyse vacuum breaker contact with Finite Element Numerical Analysis and using Response Surface Methodology and Finite Element Numerical Analysis for breaker contact. Model contact institution by ANSYS soft. Partition the model with Finite Element Numerical Analysis. Calculate the maximum electrical field. Make good use of the MATLAB soft, find the relation of electrical field with contact size. Apply theory of RSM for looking for the best result and come to the conclusion. Key words:vacuum breake
