Abstract
The invention concerns a generator, housed inside the equipment, such as a sprayer, a high voltage cascade including a voltage-gain transformer (2) and a voltage multiplier (3) arranged at the output of the transformer (2). Said transformer (2) is a double or multiple transformer, consisting of at least two elementary transformers (2A, 2B), whereof the respective primary windings (8A, 8B) are mounted electrically in parallel, and whereof the respective secondary windings (9A, 9B) are mounted electrically in series, said arrangement enabling to reduce the diameter of the cascade, to facilitate its incorporation in the sprayer or other equipment. The invention is applicable to painting robots for the automotive industry.
Claims5
A high voltage generator for electrostatic painting equipment (15), said generator comprising in particular, housed inside the equipment (15), a high voltage “cascade” (16) comprising on the one hand a voltage booster transformer (2), and on the other hand a voltage multiplier (3) placed at the output of the transformer (2), characterized in that said transformer (2) consists of a double or multiple transformer, made up of at least two elementary transformers (2a, 2B, 2C), whose respective primary windings (8A, 8B, 8C) are mounted electrically in parallel, and whose respective secondary windings (9A, 9B, 9C) are mounted electrically in series, the series mounting of the secondary windings (9A, 9B, 9C) providing an output voltage (Vs), the sum of the voltages (Vs/N) across the terminals of each of the secondary windings, and which is the input voltage of the voltage multiplier (3).
