Abstract

An einer mit Hochspannung betriebenen elektrostatischen Sprühanlage soll nach dem Abschalten der Hochspannung geprüft werden, ob die Restenergie, die noch in dem vom Hochspannungserzeuger (1) gespeisten Energiespeichersystem verblieben ist, auf einen ungefährlichen Wert abgesunken ist. Hierzu wird der Wert der elektrischen Kapazität des Energiespeichersystems bestimmt, und der Istwert der an diesem System liegenden Spannung wird gemessen. Anhand dieser Werte und unter Ausnutzung der naturgesetzlichen Beziehung, die zwischen elektrischer Spannung, elektrischer Kapazität und elektrischer Energie besteht, wird nach dem Abschalten der Hochspannung ermittelt, ob die Restenergie einen als ungefährlich vorgegebenen Wert überschreitet.

Figure 00000001
On an electrostatic spray system operated with high voltage, after the high voltage has been switched off, it is to be checked whether the residual energy which has remained in the energy storage system fed by the high voltage generator (1) has dropped to a non-hazardous value. For this purpose, the value of the electrical capacity of the energy storage system is determined, and the actual value of the voltage applied to this system is measured. On the basis of these values and taking advantage of the natural law relationship that exists between electrical voltage, electrical capacity and electrical energy, it is determined after the high voltage has been switched off whether the residual energy exceeds a value which is predefined as harmless.
