Electrostatic coating apparatus

摘要

An electrostatic coating apparatus having a built-in high-voltage (high-tension) generator which, apart from a voltage multiplier (2) in the form of a cascade circuit, which voltage multiplier (2) is constructed as a tubular component consisting of two capacitor columns (4) (which are diametrically opposite one another with respect to the feed tube (1) for the coating material) and diode groups (which are arranged on different sides of the feed tube (1) and in each case consist of diode components (6, 7) which are aligned identically in terms of circuitry and physically) can contain a transformer (9) which likewise surrounds the feed tube (1) and whose secondary winding is constructed as a coil (13) having chambers, in order to reduce the structural size of the voltage multiplier. The apparatus can be constructed as an electrostatic additional apparatus which, instead of being coupled to the output nozzle of a non-electrostatic coating gun, is coupled to its gun body. <IMAGE>
