Book excerpt: Drawn from the author's more than four decades of practical experience in the industry, The Vacuum Interrupter: Theory, Design, and Application first discusses the design and manufacture of the vacuum interrupter before delving into its general application. The book begins with a review of the vacuum breakdown process and what to consider when developing a design for a high-voltage application. It then discusses the vacuum arc and how its appearance changes as a function of current. This section concludes with an overview of existing contact materials, a summary of their advantages and disadvantages, an analysis of vacuum interrupter contact design, and considerations for the manufacture of vacuum interrupters. The next section on application describes the interruption process for low- and high-current vacuum arcs, examines the voltage escalation event that occurs if the contact gap is very small at the ac current zero, and explores the phenomenon of contact welding. It also studies the application of vacuum interrupters to switch load currents, circuit breakers, and reclosers. Owing to the increasing need for environmentally friendly interrupting systems, the development of vacuum interrupters will only intensify over time. With extensive references in each chapter for further exploration, this comprehensive guide provides essential, up-to-date knowledge to fully understand this vital technology.

Book excerpt: Title: The Vacuum Interrupter: Theory, Design, and ApplicationShelving guide: Electrical Engineering Dr. Paul Slade draws from his nearly six decades of active experience to develop this second edition of The Vacuum Interrupter: Theory, Design, and Application. This book begins by discussing the design requirements for high voltage vacuum interrupters and then the contact requirements to interrupt the vacuum arc. It then continues by describing the various applications in which the vacuum interrupter is generally utilized. Part 1 of this book begins with a detailed review of the vacuum breakdown process. It continues by covering the steps necessary for the design and the manufacture of a successful vacuum interrupter. The vacuum arc is then discussed, including how it is affected as a function of current. An overview of the development and use of practical contact materials, along with their advantages and disadvantages, follows. Contact designs that are introduced to control the high current vacuum arc are also analyzed. Part 2, on application, begins with a discussion of the arc interruption process for low current and high current vacuum arcs. It examines the voltage escalation phenomenon that can occur when interrupting inductive circuits. The occurrence of contact welding for closed contacts subjected to the passage of high currents, and for contacts when closing on high currents, is explored. The general requirements for the successful manufacture and testing of vacuum circuit breakers is then presented. The general application of vacuum interrupters to switch load currents, especially when applied to capacitor circuits, is also given. The interruption of high short circuit currents is presented along with the expected performance of the two major contact designs. Owing to the ever-increasing need for environmentally friendly circuit protection devices, the development and application of the vacuum interrupter will only increase in the future. At present the vacuum circuit breaker is the technology of choice for distribution circuits (5kV to 40.5kV). It is increasingly being applied to transmission circuits (72.5kV to 242kV). In the future, its application for protecting high voltage DC networks is assured. Audience This is a practical source book for engineers and scientists interested in studying the development and application of the vacuum interrupter Research scientists in industry and universities Graduate students beginning their study of vacuum interrupter phenomena Design engineers applying vacuum interrupters in vacuum switches, vacuum contactors, vacuum circuit breakers, and vacuum contactors It provides a unique and comprehensive review of all aspects of vacuum interrupter technology for those new to the subject and for those who wish to obtain a deeper understanding of its science and application Scientists and engineers, who are beginning their research into vacuum breakdown and aspects of the vacuum arc, will find the extensive bibliography and phenomenological descriptions to be a useful introduction
