Title: The Innovative Contributions of Frederic Burnaz
Introduction
Frederic Burnaz is a notable inventor based in Echirolles, France, recognized for his significant contributions to electrical engineering. With a total of four patents to his name, Burnaz has made strides in the development of advanced electrical switches and circuit breakers.
Latest Patents
One of Burnaz's latest patents is the vacuum electrical switch. This innovative device features an elongated vacuum cartridge with a cylindrical enclosure sealed by two end-plates. Inside, it houses two arcing contacts, one stationary and one movable, along with a coil designed to generate an axial magnetic field in the arc formation zone. The coil is uniquely structured, with one end functioning as a current conducting strip and the other end connected to one of the arcing contacts. The design includes a branch-off means, such as a magnetic circuit, to divert a portion of the main current through the coil during breaking, thereby creating the necessary axial magnetic field.
Another significant patent is the medium voltage electrical circuit breaker and switch. This device comprises first and second stationary contacts, a mobile conducting bridge with first and second movable contacts, and an operating mechanism linked to the bridge. The switch also contains a vacuum cartridge with a third stationary contact connected to the second stationary contact and a third movable contact linked to the bridge. The sequencing means in this invention is designed to manage the opening and closing sequences of the contacts, ensuring that the third stationary and movable contacts momentarily close during the operations to manage the arc associated with the other contacts.
