Abstract: A device for providing electrical protection against voltage surges. The device comprises a protector unit connected to the electrical equipment via a connection circuit including an electric current interrupter means movable between a return position corresponding to the circuit being open-circuit, and a position for closing the circuit. The interrupter means is maintained in the closed position by a blocker means. Further, the connection circuit is opened when the temperature of the unit reaches a predetermined value, via an opener means that that contains means sensitive to the heat given off by the unit. The heat-sensitive means is functionally connected to an actuator means so that when the predetermined temperature is reached, the actuator means produces a force for deactivating the blocker means.

Abstract: A device for protecting an electrical power distribution network against the overvoltages due to a lightning strike is disclosed herein. The device comprises a first electrode electrically coupled to the electrical power distribution network, a second electrode connected to a grounding conductor, focusing means capable of guiding an electric arc generated between the two electrodes toward a fractionation device, and a casing. The casing accommodates the two electrodes, the focusing means and the fractionation device.
