CURRENT ASSIGNMENT METHOD AND CORRESPONDING SWITCH ARRANGEMENT

摘要

A current assignment method and a switch arrangement are disclosed for assigning current, the switch arrangement including two series-connected switches, each including a trigger unit to check whether a preset current condition is satisfied. A signal is sent by the trigger unit of a switch which is postpositionally placed when the current condition is satisfied, the signal at least preventing the immediate triggering of a correspondingly prepositionally placed switch after being received by the corresponding trigger unit. To achieve a technically simple communication connection between switches, in at least one embodiment each trigger unit is formed so as to send but and receive the signal, and each trigger unit includes a measurement unit for measuring an energy flow direction in a subordinate switch and a conversion unit for converting from sending to receiving or from receiving to sending appropriately when the energy flow direction is reversed.

1. A method for assigning current using a switch arrangement, wherein two switches in the switch arrangement are directly connected in series according to current, and wherein each of the two switches includes a trigger unit to correspondingly check whether a current satisfies a previously given current condition, the method comprising:
sending, when the current condition is satisfied and via the trigger unit of one of the two switches which is postpositionally placed as viewed in an energy flow direction, a signal to the trigger unit of a correspondingly prepositionally placed one of the two switches; and at least not immediately triggering, after receiving the signal, the prepositionally placed one of the two switches, wherein each of the trigger units is configured to send and receive the signal, measure the energy flow direction in an associated one of the two switches, and when the energy flow direction is reversed, convert from sending to receiving or from receiving to sending.
