  • Ship power supply and - distribution systems are especially in underwater vessels to improve the operational performance, to increase the voltage stability and reduce Net 'zgurwirkun- gen very low impedance designed. Accordingly, very high, high-energy and relatively long-lasting partial and total short-circuit currents up to more than 300 kA are possible in such systems, the main sources of these short-circuit currents being the batteries and charging generators. Due to the limited space available in ships, ship circuit breakers must also be as small as possible. There is also a requirement for the lowest possible weight.

  • An arc that arises in a current-carrying ship circuit breaker when its switching contacts are opened thus leads to a gas emission of the lining material in this arc chamber. Since the gas emitted has a significantly lower temperature than the arc, the gas cools the arc and promotes the extinguishing of the arc.
  • the lining material protects itself from being destroyed by hot arc gases by releasing gas. It is therefore possible to achieve a high switching capacity with a small size and low weight of the arc chamber and thus also a low weight of the entire circuit breaker.

  • the gas-emitting lining material in the arc chamber is designed to emit different gases depending on the location.
  • the running behavior of the arc can be influenced by the gas emission. Due to a location-dependent strong gas emission, an optimum between too little and too much gas emission and thus a particularly smooth running behavior of the arc can be achieved, which enables the arc to be extinguished reliably.

Abstract

L'invention concerne un interrupteur d'alimentation de navire (7, 17), conçu en particulier pour la partie immergée des navires, comprenant au moins une boîte d'extinction d'arc (8, 18) revêtue, au moins partiellement, d'un matériau de revêtement (10) qui émet un gaz lorsqu'il est soumis à l'action d'arcs électriques. L'émission de gaz par le matériau de revêtement (10) favorise l'extinction des arcs et protège simultanément la boîte d'extinction d'arc contre l'action des arcs électriques, ce qui permet non seulement d'obtenir une puissance de coupure élevée, mais aussi de conférer de petites dimensions à la boîte d'extinction d'arc et, par conséquent, à l'espace nécessaire à l'installation de l'interrupteur d'alimentation de navire, dans un navire.
