Filed: 1941-11-10
Abstract: 577,528. Supply systems for space discharge apparatus. GENERAL ELECTRIC CO., Ltd., FRANCIS, V. J., and WILLOUGHBY, A. H. Nov. 10, 1941, Nos. 14470 and 15114. [Class 38 (iv)] A method of starting a high pressure metal vapour discharge device, which normally operates from a supply whose voltage is insufficient to initiate discharge between the main electrodes when the device is hot, comprises the following steps:-(a) applying a relatively high alternating voltage between one main electrode and an auxiliary electrode to start an auxiliary discharge; (b) replacing the alternating voltage by the normal supply which then maintains the discharge ; (c) applying the alternating voltage to the main electrodes to initiate the main discharge ; and (d) substituting the normal supply voltage for the alternating voltage. The alternating voltages employed in steps (a) and (c) may be of different magnitudes. In the system shown, the auxiliary discharge is initiated between main electrode 2 and auxiliary electrode 3 by opening switch 8 and closing contacts 11, 13 of switch 10 so that the supply voltage 4 is supplemented by the secondary voltage of a step-up transformer 6, 7 having a high resistance secondary. Switch 8 is then closed to connect electrode 3 to the supply 4 alone. Switch 9, if previously closed, is opened and contact 11 of switch 10 is moved over to 14 whereby the transformer secondary voltage and the supply 4 are applied in series to the main electrodes. Switch 9 is then closed and switch 10 opened to establish normal running connections. The transformer voltage must be suitably phased with the supply 4 when the latter is an alternating current one.
