Title: Christian Franck: Innovator in High-Voltage Circuit Breaker Technology

Introduction

Christian Franck is a notable inventor based in Zurich, Switzerland. He has made significant contributions to the field of electrical engineering, particularly in the development of high-voltage circuit breakers. With a total of two patents to his name, Franck's work focuses on improving the efficiency and safety of electrical systems.

Latest Patents

Franck's latest patents include a high-voltage circuit breaker with an improved circuit breaker rating. This innovative electrical breaker device features a method for enhanced quenching gas cooling. The design allows for cold gas to be stored in the exhaust region, with a first partial gas flow bypassing the stored cold gas and flowing into the breaker chamber. The second partial gas flow forcibly displaces the cold gas, mixing it with the first flow before entering the breaker chamber housing. This design results in improved quenching gas cooling, an increased circuit breaker rating, and a more compact breaker design. Another patent involves a gas-insulated high-voltage circuit breaker equipped with a relief duct controlled by an overflow valve. This breaker includes two arcing contacts that move relative to one another, an insulating nozzle, and a heating volume for quenching gas. The overpressure valve limits the pressure of the quenching gas, enhancing the quality of the gas stored in the heating volume.
