Abstract

A high rotation atomizer functioning with inner charging includes a high-voltage circuit which generates a high voltage that can be applied to a bell cup, from a low voltage. This high-voltage circuit includes a measuring resistor in a circuit path between the turbine casing of the turbine driving the bell cup and ground. A first measuring voltage can be tapped at this first measuring resistor, which voltage is a measure for the voltage applied at the turbine casing. A second measuring resistor is placed in a circuit path between the turbine casing and ground. A second measuring voltage is tapped at this resistor, which is likewise a measure for the voltage applied at the turbine casing. If the information gained from the two measuring voltages deviates too strongly from each other, then the control device triggers an error signal. By this means, the safety of the entire system is increased.

First claim

1 . A high-rotation atomizer functioning with internal charging comprising:
a) an outer casing; b) a rotatably mounted bell disc; c) a turbine arranged in a turbine casing, which causes the bell disc to rotate; d) a high-voltage circuit, to which a low voltage can be supplied and which generates a high voltage at an output that has been electrically connected to the bell disc, to the turbine and to the turbine casing, and comprises:
da) a high-voltage cascade;
db) a measuring resistor which is situated in a current path situated between the turbine casing and earth and at which a first measuring voltage can be tapped which is a measure of the voltage applied to the turbine casing;
wherein e) a further measuring resistor has been provided which is likewise situated in a current path leading from the turbine casing to the earth, and at which a second measuring voltage can be tapped which is a measure of the voltage applied to the turbine casing; f) a control device has been provided, to which the two measuring voltages can be supplied and which emits an interference signal when a maximum value of the difference of these measuring voltages is exceeded.

2 . The high-rotation atomizer according to claim 1 , further comprising an optical or acoustic fault signal which can be triggered by the interference signal of the control device.

3 . The high-rotation atomizer according claim 1 , wherein the low voltage supplied to the high-voltage circuit can be switched off by the interference signal of the control device.

4 . The high-rotation atomizer according claim 1 , wherein the safety function of a higher-ranking plant control system can be activated by the interference signal of the control device.
