发明名称 AUDIBLE ALARM SYSTEM TO PREVENT EARTHING IN HIGH-VOLTAGE CELLS
摘要 <p>It is meant to provide a complement for the conventional optical indicator (9) of the presence of voltage in a high-voltage line (2), and is embodied as an audible alarm (1) powered by the high-voltage line (2) through a capacitive and/or resistive bushing or coupling (3), establishing in the power supply circuit of said audible alarm a normally open microswitch (4) activated by the actuation lever (5) of the cell earthing isolator, so that in the coupling operation of said lever (5) and before the isolator is actuated the circuit of the audible alarm (1) is closed and thereby said alarm is activated, warning the worker that the operation must be stopped and the voltage must be eliminated from the line (2). &lt;IMAGE&gt;</p>
