Abstract
The present invention is a visualization luminous device, adapted for electric motors of equipments supplied by the three-phase voltage, allowing to visualize with certainty if it has there or not presence of voltage downstream from the blades of the disconnecting switch or the circuit breakers at the time to put down at energy zero.
Claims2
A visualization luminous device to put down at energy zero, adapted for electric motors of equipments supplied by the three-phase voltage, said device comprising:
- (a) The red lenses in poly carbonate having a translucent part;
- (b) The red lenses in poly carbonate having a threaded part screwed to threaded socket in poly carbonate fixed at an hexagonal nut in black poly-carbonate connected to the case of the device in poly carbonate filled of epoxy;
- (c) The metal screws limited by the separators allow the wiring link to the diodes;
- (d) The electric identification signs allow to identify the output of standard ground, and the letters (A)(B)(C) allow to identify the electric inputs;
- and
- (e) The resistances connected to the device by the wires and metal screws allow to connect the wires to the diodes, to the resistance, to the red lights and to the connections, to a link to ground by the screws at the electric ground of the device.
