| DWPI Title: System for discharging energy source, has circuit providing controlled discharge path via relayed shunt-resistor network, positive terminal and negative terminal to connect circuit to external voltage source, meter circuit to measure instantaneous voltage of external voltage source, discharge switch |
| Abstract: A system or method for discharging an energy source is disclosed. The system includes a circuit that provides a controlled discharge path through a relayed shunt-resistor network. A positive terminal and a negative terminal are provided for connecting the circuit to an external voltage source. A meter measures an instantaneous voltage of the external voltage source. A discharge switch is connected between the input terminal and the shunt-resistor network. A meter switch connects to the meter circuit to a voltage meter to display the voltage measured across the positive and negative terminal. The positive and negative terminals are electrically isolated when the discharge switch and the meter switch are switched to an open state. The high voltage discharge unit gently dissipates the stored energy on a capacitor, properly disabling a firing system, by providing a controlled discharge path through a relayed high voltage shunt resistor network. |
| Use: System for discharging an energy source. |
| Advantage: The handheld device allows a non- violent discharge of high voltage energy sources such as high voltage capacitor or high voltage power supplies. The high voltage discharge unit gently dissipates the stored energy on a capacitor, properly disabling a firing system, by providing a controlled discharge path through a relayed high voltage shunt resistor network. A maximum operating voltage of 10,000 volts and maximum energy dissipation of 600 Joules maximum capacitive dissipation is provided. |
| Novelty: The system for discharging an energy source has: a circuit that provides a controlled discharge path through a relayed shunt-resistor network; a positive terminal (15) and a negative terminal (16) for connecting the circuit to an external voltage source; a meter circuit for measuring an instantaneous voltage of the external voltage source; a discharge switch (112) connected between the input terminal and the shunt-resistor network, and configured to the external voltage source; and ameter switch connected to the meter circuit for connecting the meter circuit to a voltage meter to display the instantaneous voltage measured across the positive terminal and the negative terminal, where the positive and negative terminals are electrically isolated when the discharge switch and the meter switch are switched to an open state. |
