Title: Jacques Ecrabey: Innovator in Electrical Apparatus Design

Introduction

Jacques Ecrabey is a notable inventor based in Guilherand-Granges, France. He has made significant contributions to the field of electrical engineering, particularly in the design of power supply systems. His innovative approach has led to the development of a unique patent that addresses critical issues in electrical apparatus.

Latest Patents

Ecrabey holds a patent for "Protecting a power supply including a plurality of batteries in parallel against an external short-circuit." This invention involves an electrical apparatus that includes a circuit breaker with a specific breaking capacity and breaking current. The design features a DC voltage source comprising two batteries connected in parallel, which are linked in series with the circuit breaker. The system is engineered to ensure that the sum of short-circuit currents of the batteries exceeds the breaking capacity. Each battery consists of a first branch with storage batteries and a switch in series, and a second branch that is parallel to the first, containing a free-wheeling diode. Additionally, an ammeter measures the output current, while a control circuit is designed to detect short-circuits. This control circuit keeps a majority of switches open while closing one switch to allow a current through the circuit breaker that is higher than the breaking current but lower than the breaking capacity.

Career Highlights

Throughout his career, Jacques Ecrabey has worked with prominent organizations, including the Commissariat à l'Énergie Atomique et aux Énergies Alternatives and DCNS. His experience in these institutions has contributed to his expertise in electrical systems and innovations.
