Title: ELECTROSTATIC COATING CABLE MAINTENANCE DEVICE
Abstract:
The purpose of the invention is to reduce time required for the work of replacing divided cables. An electrostatic coating cable (6) includes a power supply line (12) for supplying power to a high-voltage generator (2), a signal line (14) for controlling the high-voltage generator (2), and an earth line (16). The power supply line (12) is connected through a first diode (22) and a first test wire (18) to the earth line (16), and the signal line (14) is connected through a second diode (24) and a second test wire (20) to the earth line (16). The first and second diodes (22, 24) prevent current from flowing through the first and second test wires (18, 20) when an electrostatic coating machine (1) is in operation. The first and second test wires (18, 20) and the first and second diodes (22, 24) are housed in a cable connecting portion (8) for connecting an adjacent divided cable (10). While the electrostatic coating machine (1) is being halted, a test voltage is applied to the earth line (16).
