ELECTRICAL POWER SUPPLY FOR ELECTROSTATIC COATING MATERIAL DISTRIBUTION APPARATUS AND DEVICE FOR PREVENTING THE ELECTROSTATIC CHARGE OF SUCH AN UNPLEASANT DEVICE

摘要

The invention relates to a device intended to prevent the use of a power source with a low electrostatic voltage, whether grounded or not grounded. / P p OF ELEMENTS 30, 32 , 34 CONNECT THE CIRCUIT TO THREE-WIRE SUPPLY 20, 22, 24. THE CIRCUIT INCLUDES AN ELECTROSTATIC VOLTAGE GENERATOR 126, 154, A FIRST CIRCUIT THAT CONNECTS THIS GENERATOR TO THREE-WIRE POWER SUPPLY, AND A CIRCUIT THAT DETECTS THE VOLTAGE BETWEEN The active wire 20 and the ground wire 24 of the three-wire power supply in order to prevent the application of the device for spraying a coating material in the event of poor grounding or failure to set the substrate.
