真空断路器(VCB)是为了满足日益增长的能源消耗和各个领域的国家安全需求而开发和广泛应用的。因此，例如，168千伏两断口瓷型和100千伏一断口断路器已经出现在日本市场，目前正出口到世界各地的市场。真空断路器中断真空中的电流，这意味着它们不会排出有时对人体有害或对环境造成影响的溶解气体。因此，从本质上讲，它实现了材料的回收利用和对人体的安全，也不会产生全球变暖的影响。能量是人类日常生活中极其重要的物质基础，各种类型的断路器在输配电系统中扮演着重要的角色，通过在多种情况下切换系统来维持系统的可靠性和安全性。真空断路器具有开断能力大、体积小、成本低等优点，在未来将得到更广泛的应用，而此时此刻，我们认为非常值得深入探讨和思考真空断路器的未来发展趋势。本文将回顾日本在这方面的发展成果，并对这些成果的反映作一陈述，并对21世纪的工程学科进行讨论。这些将包括回收、对人体的保障措施以及VCB的无火性质；并将证明VCB的开发工作现在和未来都在日本进行着奇妙的探索。
Vacuum circuit breakers (VCBs) have been developed and widely applied in Japan to meet the requirements of increasing energy consumption and also in national security of various areas. As a result, for example, a 168 kV two break porcelain type and a 100 kA one break VCB have already appeared in the Japanese market and they are currently being exported to world-wide markets. VCBs interrupt currents in vacuum, and this means they do not exhaust dissolved gases which are sometimes harmful to the human body or cause effects on the environment. Therefore, by its nature, the recycling of materials and safety to the human body have been realized, and also no global warming effects would be expected. Energy is extremely essential and important in human daily life, and many types of circuit breakers play important roles in electrical power transmission and distribution systems to maintain the systems reliability and safety by switching the systems under several conditions. Since vacuum circuit breakers possess a lot of advantages such as high current interrupting capabilities, small size, and low cost, they will be used much more in the future, and at this moment, we believe it is very worthy to discuss and consider thoroughly future trends of VCBs. In this paper, the results of the developments in Japan will be reviewed, the reflection of the results will be stated, and the subjects of engineering in the 21st century will be discussed. These will include recycling, safeguards to the human body and the fireless nature of VCBs; and it will be demonstrated that the developmental works of VCBs are being wonderfully explored in Japan now and in the future.
