Contactors for Improved Aircraft Electrical Power Distribution Systems.

摘要

Simple modifications to reduce the control signal current requirements and improve performance of existing electromechanical contactors are discussed in detail. The design of experimental ac and dc solid state contactors is given together with a detailed discussion of their advantages,disadvantages and performance. In this discussion,certain performance characteristics,important in contactor operation,are explained:it is believed that these are not generally acknowledged. Both solid state,and electromechanical contactors in their modified form,are likely to be required for use in improved aircraft electrical power distribution system of the future,since adoption of remote control of electrical loads direct or by way of multiplex systems offers the possibility of substantial economies in installed mass.
