Inventor: ARENA OCHOA GUIDO
IPC: H05B41/285
Filed: 2010-05-20
Abstract: A full-wave electronic inverter for supplying one or more low-pressure gas discharge or fluorescent lamps, which inverter is protected by a circuit containing a small tubular-core saturable transformer which has the inductive reactance necessary and sufficient for deflecting, from the circuit thereof, the asymmetrical waves which are at a frequency higher than the frequencies stipulated by design and are produced by said lamps at the end of the service life thereof, preventing the inverter from burning out, as occurs with inverters of that type which do not have said circuit which also enables the situation in which, although the inverter is still being connected to the supply circuit, the inverter does not consume energy, even though said lamp or lamps is/are connected to the circuit thereof, until said lamps are replaced with new lamps. This inverter has a starting button which is used to deenergize the inverter each time the latter operates for the first time with new lamps.

Abstract: Electrical switchgear which combines, connected electrically in series, a visible disconnect switch (operated by a main switch actuator) and a circuit breaker module (which may also be termed an interrupter) including circuit breaker contacts which are opened and closed by an electrically-activated magnetic actuator and capable of interrupting fault currents. The magnetic actuator is stable in either a breaker-closed state or a breaker-open state without requiring electrical current flow through the magnetic actuator. An interlock is provided such that, as the main switch actuator begins to move from its switch-closed position to its switch-open position, the breaker-closed state is destabilized to open the circuit breaker contacts. An interlock is also provided such that the circuit breaker contacts cannot close while the visible disconnect switch is open.
