Abstract (en)
A powder spray device which is set up for a simultaneous internal and external powder discharge has a high voltage source (6), an earth electrode (10), at least one outer high voltage electrode (5) and several inner high voltage electrodes (2). The high voltage source is connected via connecting elements (3,4) made of highly resistive material not only to the outer high voltage electrode but also to a ring (1) made of highly resistive material, over whose periphery the inner high voltage electrodes are distributed evenly. As a material for the highly resistive components, a plastic is used which is filled with graphite, rust or other conducting material.
