D. Mergerian; WESTINGHOUSE ELECTRIC CORP BALTIMORE MD
|
 | A switch is designed which is capable of conducting 20,000 amperes and of holding off 100,000 volts after opening. This switch is to be employed in switching the energy from a 1 Mjoule superconducting coil. The switch element is a vacuum interrupter which is driven by a hydraulic actuation mechanism which can open ten pounds of contacts through a distance of 0.5 inch in 2 msec. Upon separation of the ... |

Michael A. Lutz; HUGHES RESEARCH LABS MALIBU CA
|
| The general objective of this program has been to design a switch suitable for use in inductive energy storage power supplies. This switch consists of two major components, one for inductor charging (bypass switch) and one for high voltage direct current interruption (interrupter tube). Within the general objective of this program, there are six primary tasks: (1) evaluate the various bypass switch candidates and make a selection, (2) design the ... |

W. E. POCOCK; NAVAL SHIP RESEARCH AND DEVELOPMENT LAB ANNAPOLIS MD
|
| The handbbok is presented as a guide for design engineers, operating personnel, and all those concerned with the design and/or selection as well as maintenance and operation of circuit-interrupting equipment for deep-submergence use. It is not meant to be a primer for the design of circuit-interrupting devices in general, but rather to provide design guidelines and component specification and selection criteria for those problems peculiar to the operation of such ... |

|
| A focused, Q-spoiled laser was used to induce electrical breakdown of the solid dielectric between two charged electrodes. The effect of the following parameters on the breakdown delay was studied: laser focal point, applied voltage (30-85 KV), charging polarity, laser power (20-90 MW), dielectric thickness (10-20 mils), and dielectric type. Delay times as short as 3 nsec, with 1 nsec jitter, were recorded. Graded dielectrics were found to decrease switch ... |

| Authors:
George W. Zepko; STEVENS INST OF TECH HOBOKEN N J DAVIDSON LAB
|
| The report describes the steps to be taken in the fabrication of switch elements for a solid-dielectric low-inductance switch which can be used in high-energy discharge circuits. The elements are used in a type of switch having an inductance of 1 x 10 to the minus 9th power H, current carrying capability of 1000,000, and switch delay time of from 0.1 to 0.0000003 sec. Switches of this kind have been ... |

L.D. Dickey; A.J. Marek; W.M. Drum; CHANCE VOUGHT CORP DALLAS TX
|
| A study program was conducted to establish and evaluate contactless switching design techniques for application to aircraft electrical systems. Design concepts utilizing semiconductor devices were investigated to provide an effective and reliable aircraft electrical power switching and control system. Typical circuits have been designed that will perform the functions of con ventional switches, relays and circuit breakers, including switching and control of the primary bus. Breadboards have been constructed and ... |

| Authors:
D. D. Wheeler; GENERAL DYNAMICS/ASTRONAUTICS SAN DIEGO CA
|
| The object of the test was to make an evaluation test of the propellant depletion switches in order to determine the satisfactory performance of the fuel and liquid oxygen switches and the respective control packages; and to determine the capability of the switches to withstand simulated flight vibration conditions.
