excitron|ˈɛksɪtrɒn|
[f. excitation 5 + -tron.]
A kind of mercury-arc rectifier having a pool cathode and a single anode, and capable of handling large currents; it differs from an ignitron in having a cathode hot spot maintained continuously and a grid to control the output.
1940O. K. Marti in Trans. A.I.E.E. LIX. 928/2 Tests encouraged the Allis-Chalmers Manufacturing Company to build a six anode rectifier, consisting of six single tanks using an ignition-excitation system for the main arc with a continuous cathode spot... This type of rectifier has been called the Excitron rectifier. Ibid. 929/1 (caption) A 600-volt Excitron with control cabinet. 1950P. G. Andres Survey Mod. Electronics vi. 248 An important improvement in the field of mercury-arc rectification consisted in the development of a single-anode rectifier..equipped with auxiliary electrodes for establishing and controlling the arc current. A group of such individual tanks are assembled to produce a polyphase rectifier termed an Excitron. 1958Engineering 14 Mar. 341/3 The excitron uses the conventional continuous excitation (supplied by an auxiliary d.c. source) throughout every cycle. |
