Estimating the term…
The disclosure relates to a method for establishing a defined state in an electrochemical system connected to an AC/DC converter via a switch disconnector to exchange electric power. At least one DC connection of the electrochemical system is connected to the AC/DC converter via the disconnecting switch. The method includes, in a first operating state, closing a first switch to establish an electric connection between the DC connections of the electrochemical system. The application additionally relates to a disconnecting device, a power converter, and to an assembly.
A method for establishing a defined state in an electrochemical system which is configured to be connected via a disconnecting device to an AC/DC converter for exchanging electric power,
A disconnecting device comprising one or two disconnecting switches for connecting an electrochemical system to an AC/DC converter for exchanging electric power, wherein the disconnecting device has two DC inputs, two DC outputs and two current paths, wherein each current path connects a DC input in each case to a corresponding DC output, and wherein a disconnecting switch is arranged in one or each of the current paths, wherein in each case a DC output of the disconnecting device can be connected to a DC connection of the electrochemical system, and wherein the disconnecting device further comprises a first switch via which an electrical connection between the DC outputs can be established.
