Definitions

  • the invention relates to an electrical system according to the preamble of claim 1.
  • the individual cells usually work with a voltage of approximately 3.6 V.
  • a voltage of more than 300 V is required, so that more than one hundred such cells must be correspondingly connected.
  • Some vehicles are already working with voltages of around 700 V today.
  • the voltage-carrying parts are well insulated, so that in normal operation no voltage can be transmitted to users.
  • it can - in contrast to a stationary system - quickly come to an incident in which it comes to significant mechanical deformations. So z.
  • electrical insulation is damaged and high voltages are transmitted to parts with which the user can come into contact. This can lead to serious injury or even death of injured persons.
  • high voltages occur, for example, in houses with photovoltaic systems installed on their roofs. If a fire occurs, the extinguishing firefighters are exposed to a great danger, since the possibility of a flashover over the firefighting water to the people can not be excluded at high voltages.
  • the invention has the object of providing an electrically system according to the preamble of claim 1 in such a way that such dangers can be safely avoided after an unforeseen event.
  • Memory / converter cells are provided in the normal operation of the electrical system closed disconnectors, which are designed and / or arranged so that they are opened when triggered the event sensor, the high voltage in an unforeseen event in smaller, harmless Tensions are divided.
  • the event sensor is advantageously designed as an impact sensor.
  • the disconnectors between photovoltaic elements which are so-called converter cells, are triggered, for example by a smoke detector or another fire detector. Again, the high voltage then in smaller harmless Distributed voltages so that there is no danger to firefighters when deleting them.
  • the invention is applicable, inter alia, in all electrically powered vehicles.
  • a means of transport here are all devices for transporting people and / or goods by land, on the water and in the air.
  • electrically driven is meant all means of locomotion that are at least partly electrically powered.
  • hybrid vehicles some of which are powered by an electric motor and some by an internal combustion engine.
  • the consumer circuit here includes in particular the drive. In the case of a photovoltaic system, however, the load circuit has an inverter and possibly a power store.
  • the memory / converter cells should be all voltage-storing and all voltage-generating cells.
  • memory cells for example, rechargeable lithium-ion cells, or pure charge storage such.
  • B. capacitors are used.
  • the converter cells include, among others, fuel cells and photovoltaic cells.
  • an event sensor a dedicated sensor for the operation of the circuit breaker can be used.
  • the signal of an event sensor is used, which is present anyway.
  • the impact sensor of an existing airbag and, as an example of a house with photovoltaic system, an already installed smoke detector can be mentioned here.
  • the costs for the electrical system according to the invention can be reduced in this way.
  • At least one additional isolating switch which is in a closed position during normal operation of the electrical system, is provided between the series-connected storage / converter cells and the consumer circuit.
  • the consumer circuit can be disconnected from the memory / converter cells in the event of an unforeseen event.

  • the memory / converter cells can then, when the means of locomotion is at rest, separate from the load circuit.
  • the combined disconnectors / main switches are designed so that they basically act as a switch. Ideally, the potential is reduced to ground after switching over a resistor.

  • the circuit breaker In the normal, closed position of the circuit breaker is therefore on the contact pin electrical connection between tween the two contact rings. This means that the two memory cells are connected in series by the circuit breaker. After triggering the event sensor, the se connection is disconnected and thus the series connection is canceled.
  • the operation of the circuit breaker can be done in different ways.
  • a solenoid can be provided at each disconnect switch, which is supplied by a conventional 12 V battery.
  • an energy accumulator is provided which presses the circuit breaker in its open position.
  • the circuit breaker is therefore closed only when the battery voltage is applied to the solenoid.

  • This refinement has the additional advantage in the case of a means of locomotion that a division of the voltage likewise takes place with each switching of the means of locomotion into the rest position.
  • a gas generator is particularly advantageous, which is triggered via the event sensor, wherein the circuit breaker can be brought by the gas pressure generated by the gas generator from the closed to the open position.
  • the gas pressure generated by such gas generators is usually so high that it also acts under adverse circumstances and safely conveys the contact pins in the open position of the circuit breaker.
  • the gas has a very positive effect if, despite the speed with which the circuit breakers open, an arc should occur. In this case, the gas acts as a spark extinguisher.
  • the switching tube therefore advantageously has notches between the disconnectors.
  • a notch here is to understand any reduction in the inner diameter of the switching tube, regardless of whether it comes about, for example, by a bead or by webs.
