  • the invention relates to a circuit breaker, in particular a line circuit breaker, which works with a semiconductor element.
  • Circuit breakers in the form of line circuit breakers let a short-circuit current of 1000 to about 6000 A flow for a few milliseconds when a downstream device is short-circuited. Therefore, these devices are designed today so that they can withstand these high-current pulses, as they occur especially when commissioning, without damage. This makes circuit breakers more expensive, on the one hand, and on the other hand, the required construction volume is larger.

Its internal resistance rises abruptly with increasing voltage at the working electrodes. Voltage is then abruptly applied to a trigger element of a relay arranged parallel to the semiconductor element, so that the relay can then open an interrupter contact arranged in the cable line.
  • the interrupter contact can open permanently, that is to say can be designed to be storage.
  • it can be a bistable relay.

Despite the inevitable effect of an internal body diode in FETs, the arrangement of the two FETs can block AC voltage. In the event of a short circuit, such an arrangement can limit the current to less than 50 to 60 A instead of the 6 KA otherwise customary in circuit breakers. Particularly fast special versions are not required as relays, but standard quick-release relays are sufficient.

Abstract

Un sectionneur de puissance, notamment un disjoncteur de protection de canalisation, utilise un élément semiconducteur (1). Sa résistance interne est faible lorsqu'une tension déterminée de commande (2) est appliquée à une électrode de commande (3) et qu'une tension de fonctionnement (4) est appliquée à des électrodes de travail (5) situées dans le sens de passage du tracé de la ligne. La résistance interne monte brusquement à mesure que la tension appliquée aux électrodes de travail (5) augmente. Un organe de déclenchement (7) d'un élément qui exerce une fonction de relais est connecté en parallèle à l'élément semiconducteur (1). L'élément relais coopère avec au moins un contact disjoncteur (8) situé dans le tracé de ligne dans le sens de l'ouverture.
