Latest Patents
One of Philippe Legendre's latest patents is an electrical contact device and a low-voltage single-pole phase unit incorporating such a device. This invention relates to an electric contact device that is part of an electric switching device, which allows or interrupts the passage of electric current. The device comprises at least one moving support and a contact pad mounted on the moving support. The moving support can position the contact pad in contact with a fixed contact surface connected to an electrical conductor. The contact pad features a contact surface designed to cooperate with the fixed contact surface, which includes a first spherical portion for actual contact and a second convex portion that varies in shape.
Another significant patent is for a single-pole switching unit that includes a housing with a moving contact bridge and a pair of fixed contacts. These fixed contacts cooperate with the moving contact bridge and are connected to a current intake conductor. The design includes two electric arc cutoff chambers that open onto the moving contact bridge's open volume. Each cutoff chamber is connected to an exhaust channel featuring a rotating gate that operates based on the passage of switching gases.
