Definitions

  • the invention relates to a self-learning electronic fuse.
  • a fault from electrical consumers can affect the electrical supply device, for example a power supply.
  • a short-circuit event or a short-circuit-like overcurrent such as occurs when motors start up due to the high current requirement, can initiate a shutdown of the supply device in the consumer branch.
  • Consumer feeders with different current requirements are generally connected to an electrical supply device. These load feeders are usually equipped with miniature circuit breakers or automatic circuit breakers with certain tripping characteristics. This ensures that an overloaded branch is switched off and that the remaining branches can continue to run unaffected.
  • a short-circuit protection of clocked power supplies is generally implemented electronically. It has been shown that an electronic short-circuit protection intervenes so quickly in the event of a fault, that is to say when a short circuit or a short-circuit-like overcurrent occurs, that upstream protective elements such as circuit breakers or circuit breakers no longer trip. The consequence of this is that the faulty branch can no longer be identified and the entire system part, including the faultless parts, is switched off.
  • circuit breakers or circuit breakers on the market cannot trip safely. Electronic fuses trip safely and their function can replace circuit breakers or automatic circuit breakers.
  • the solutions on the market work on the principle that a predefined switch-off characteristic or switch-off curve is set to the current level to be monitored by means of an actuator, for example a potentiometer.
  • the object of the invention is to improve the function of an electronic fuse.

  • the size of the time window and / or the granularity of the recording can be set.
  • the measured values to be monitored in accordance with the monitoring mode are recorded in an analysis process, a reference is determined from this and this is stored;
  • the series of measurements and possibly the monitoring modes can be transferred to other self-learning electronic fuses with mobile memory or using a communication system.
  • the communication system can have the following interfaces: an interface to a bus system, an interface to the Internet, a GSM interface, a UMTS interface, a USB interface or a radio interface.
