Title: The Innovations of Jean-Pierre Kersusan

Introduction

Jean-Pierre Kersusan is a notable inventor based in Grenoble, France. He has made significant contributions to the field of electrical engineering, particularly in the development of circuit breakers. With a total of 2 patents to his name, Kersusan's work reflects a commitment to enhancing electrical safety and efficiency.

Latest Patents

Kersusan's latest patents include an innovative electrical circuit breaker with a rotating arc and self-extinguishing features. This three-phase circuit breaker is designed with an arc extinguishing chamber for each pole, housing a pair of contacts—one stationary and one movable. It incorporates a coil to rotate the arc and an exhaust channel in at least one contact, allowing for gas outflow between the extinguishing chamber and the expansion volume of an enclosure filled with SF6. The extinguishing chamber is designed with a square or rectangular cross-section to effectively resorb the gas plug after braking the gas rotation movement, thereby improving gas stirring within the chamber.

Another significant patent by Kersusan is for a self-extinguishing expansion SF6-gas circuit breaker. This invention features tubular contacts with guiding ribs that counteract any vortex-effect swirling gas flow between the first extinguishing chamber and the second expansion chamber. The inclusion of these ribs enhances the dielectric withstand of the circuit breaker and prevents arc restriking within the contacts.
