Title: Emile Schreurs: Innovator in Fault Current Limiting Technology
Introduction
Emile Schreurs is a notable inventor based in Vasterang, Sweden. He has made significant contributions to the field of electrical engineering, particularly in the development of fault current limiters. With a total of 3 patents to his name, Schreurs has demonstrated a commitment to innovation and technological advancement.
Latest Patents
One of Schreurs' latest patents is a current limiter that features a fault current limiter in which a resistor is inserted by a running arc. This design allows the arc to burn in a commutating unit until the current reaches zero-crossing. Upon passing through zero, the arc is extinguished, and the current is redirected to a shunt resistor. The commutating unit includes a gap-formed nozzle where the arc burns, defined by two nozzle halves made from a material that emits gas under the influence of the arc. Close to the nozzle inlet, a pressure accumulating chamber builds up overpressure during the arcing time. After the current zero-crossing, the hot arc residues are effectively vented using the overpressure in the chamber, which is divided into small sub-volumes by metal plates for cooling and guiding the gas flow.
Another significant patent by Schreurs is a fault current limiter that comprises a contact device connected to a resistor/inductor combination. This combination includes a series connection of a first and a second resistor, along with a third resistor/inductor connected in parallel. The second resistor is designed with superconducting properties, ensuring that the transition from superconducting to normally-conducting state occurs when the critical current density is reached.
