Definitions

  • a shutdown device for disconnecting an electrical energy source from a load and circuit devices with a shutdown device
  • the invention relates to a shutdown device for the separation of an electrical energy source from a load. Furthermore, the invention relates to a circuit system having an electrical energy source, a load and a shutdown device.
  • Fig. 1 shows schematically such a known shutdown device.
  • the shutdown device comprises a battery 2, which is electrically connected to a consumer 3.
  • a circuit breaker 10 is connected in series.
  • Such circuit breakers allow the repeated shutdown of such a system, especially under load.
  • the disadvantage, however, that circuit breakers are very expensive.
  • Disposable switch remains open, and in case of malfunction of the one-time switch of at least one other one-time switch for disconnecting the power source is used by the consumer and for connecting the power source to the consumer.
  • the shutdown device allows the separation of an electrical energy source from a consumer even in the event that the load has exceeded a critical value, for example, at full load.
  • the number of one-time switches determines the number of permitted shutdowns under such a condition. If only a small number of such shutdowns required, arise with the inventive shutdown device due to the ability to use cost-effective disposable switches instead of expensive circuit breakers, cost advantages.
  • Another object of the invention is a circuit system comprising an electrical energy source, a consumer and a shutdown device according to the invention, wherein the shutdown device is connected between the energy source and consumer for disconnecting the consumer from and for connecting the consumer to the power source.
  • the cut-off means is connected between one pole of the power source and the load, and another switch is connected between the other pole of the power source and the load. This allows complete electrical isolation of the load from the power source.
  • the circuit system is preferably set up in such a way that, to disconnect the load from the energy source, a one-time switch is first opened, and subsequently the further switch is opened. This ensures that the other switch can be opened without current and is not charged in this way.
  • the further switch may be a one-time switch of an intermediate between the energy source and consumer further shutdown system. In this way, the number of permitted shutdowns under load can be additionally increased.

  • the shutdown device 1 is connected between a pole of the power source and the load 3.
  • the shutdown device 1 comprises two one-time switch 4, which are connected in parallel.
  • the one-time switch 4 are designed such that, by switching in the presence of a load exceeding a critical value while disconnecting the electrical connection between the energy source 2 and the consumer 3, these become inoperative.
  • a one-time switch For example, a burnable relay may be used which will be destroyed in the presence of a high current and the resulting light spark.
  • a conventional relay could be used in series with an explosive device ignitable when the critical value for the load was exceeded.
  • the switch-off device 1 is set up such that apart from a one-time switch 4 which is provided for disconnecting the energy source from the consumers and for connecting the energy source to the consumer, the at least one other one-time switch remains open, and in the case of a malfunction of the one-time switch 4 the at least one other one-time switch 4 is used for disconnecting the energy source 2 from the consumer 3 and for connecting the energy source 2 to the consumer 3.
  • the circuit system comprises a further switch 5, which is interposed between the other pole of the power source 2 and the load 3.
  • both the switch 5 and the one-time switch 4 of the shutdown device 1 is opened or closed.
  • both the switch 5 and the one-time switch 4 can be opened without the switches being damaged.

Abstract

L'invention concerne un dispositif de coupure (1, 1 ') servant à séparer une source d'énergie électrique (2) d'un consommateur (3). Ce dispositif de coupure (1, 1 ') comporte au moins deux disjoncteurs à usage unique (4) qui, lorsqu'ils assurent une connexion en présence d'un consommateur dépassant une valeur critique, coupent une liaison électrique et deviennent ainsi incapables de fonctionner. Les disjoncteurs à usage unique (4) sont montés en parallèle, et le dispositif de coupure (1, 1 ') est conçu pour que, à l'exception d'un disjoncteur à usage unique (4) qui est destiné à séparer la source d'énergie électrique (2) du consommateur (3) et à relier la source d'énergie électrique (2) au consommateur (3), l'autre disjoncteur à usage unique (4) reste ouvert, et pour que, dans le cas où un disjoncteur à usage unique (4) devient incapable de fonctionner, l'autre au moins un disjoncteur à usage unique (4) soit utilisé pour séparer la source d'énergie électrique (2) du consommateur (3) et pour relier la source d'énergie électrique (2) au consommateur (3).
