    • A power supplying device for the operation of a gas discharge container for the treatment of metallic workpieces. For the provision and the adjustment of the operating voltage the power supplying device comprises a transformer, a thyratron-or thyristor full-wave rectifier located in the secondary circuit and an ignition control device for the ignition of the rectifiers. The power supplying device further comprises a device monitoring the discharge and in response to which the ignition control device further serves as a quick-action switch interrupting the discharge during a number of periods. An inductance is located in the primary circuit having such design that the increase of the operating voltage following every zero passage is retarded. Resulting is an extension of the interruption of discharge occuring at every zero passage of the operating voltage causing minor discharge disturbances on the workpiece surface to decay.
    • 一种用于操作用于处理金属工件的气体放电容器的供电装置。 为了提供和调整工作电压,供电装置包括位于二次回路中的变压器,闸流管或晶闸管全波整流器和用于整流器点火的点火控制装置。 供电装置还包括监测放电的装置,并且响应于此,点火控制装置还用作在多个周期期间中断放电的快动开关。 电感位于初级电路中,具有这样的设计,使得每个零通道之后的工作电压的增加被延迟。 导致在工作电压的每零通过时发生放电中断的延伸,导致工件表面上的轻微的放电干扰衰减。
