用于电力系统故障电流限制器的快速合闸开关研究     

邹积岩  董恩源  陈金祥 《上海大学学报(英文版)》2002,6(1):92-96

This paper presents a new type of fault current limiter(FCL) based on fast-closing switch,which is composed of a capacitor bank and a reactor in series.The main control component is a fast-closing switch connected in parallel with the capactitors,which is drien by the electromagnetic repulsion force.It can response the order within 1 ms.When fault occurs,the switch closes and the capacitors are bypassed.and the fault current is limited by the reactor,Simulation analysis and experiment show that the electromagnetic repulsion force actuator can meet the demand of fast-closing switch,it is feasible to develop the FCL with low cost and high reliability.  相似文献

对西部大开发的认识     

侯明 《三门峡职业技术学院学报》2005,4(3):63-65

在经济全球化的今天,西部大开发不仅关系到缩小国内经济发展的地域差异态势,而且又直接影响我国争取中亚丰富矿藏资源的进口,具有重大的战略意义。由于西部经济发展的劣势明显,发展的进程只能是渐进式,不可能是突进式的。西部大开发必须重视有关政策的制定与落实,注重生态环境的建设与保护,充分利用市场操作的手段。  相似文献   

Bridging In-school and Out-of-school Learning: Formal, Non-Formal, and Informal Education   总被引：1，自引：0，他引：1  

Haim Eshach 《Journal of Science Education and Technology》2007,16(2):171-190

The present paper thoroughly examines how one can effectively bridge in-school and out-of-school learning. The first part discusses the difficulty in defining out-of-school learning. It proposes to distinguish three types of learning: formal, informal, and non-formal. The second part raises the question of whether out-of-school learning should be dealt with in the in-school system, in view of the fact that we experience informal learning anyway as well as considering the disadvantages and difficulties teachers are confronted with when planning and carrying out scientific fieldtrips. The voices of the teachers, the students, and the non-formal institution staff are heard to provide insights into the problem. The third part discusses the cognitive and affective aspects of non-formal learning. The fourth part presents some models explaining scientific fieldtrip learning and based on those models, suggests a novel explanation. The fifth part offers some recommendations of how to bridge in and out-of-school learning. The paper closes with some practical ideas as to how one can bring the theory described in the paper into practice. It is hoped that this paper will provide educators with an insight so that they will be able to fully exploit the great potential that scientific field trips may offer. This paper appears as a chapter in: Eshach, H. (2006). Science Literacy in Primary Schools and Pre-Schools, Netherlands: Springer.  相似文献
