Abstract
An electrical network is equipped with feed-in devices, loads, a distribution grid arranged therebetween, at least one semiconductor switch, and at least one electromechanical switch for separating a feed-in device or a load in the event of a fault. The feed-in devices and loads are arranged in groups which are connected together by a busbar and paired semiconductor switches. Each feed-in device and load can be separated from the grid by an electromechanical switch in the event of a fault, and the individual groups of feed-in devices and loads can be separated from one another by the semiconductor switches in the event of a fault in order to prevent cross currents on the busbar.
Claims15
An electrical network comprising:
- feed-in devices and loads connected to a common busbar, the busbar being directly connected to an AC/DC converter;
- and
- a distribution network arranged between the feed-in devices and the loads, the distribution network including at least one semiconductor switch connected to the busbar and arranged to control current flow on the busbar, and at least one electromechanical switch to isolate one or more of the feed-in devices or one or more of the loads in the event of a fault, wherein
- the feed-in devices and loads are arranged in groups of the feed-in devices and loads, which are connected to one another via the busbar and associated semiconductor switches,
- each of the feed-in devices and the loads is associated with a separate electromechanical switch from among the at least one electromechanical switch and each of the at least one electromechanical switch is configured to disconnect an associated feed-in device or load from the electrical network in the event of a fault, and
- individual groups of the feed-in devices and loads are configured to be disconnected from one another via the associated semiconductor switches in the event of a fault to prevent cross currents on the busbar, wherein,
- in the event of a fault, after an electromechanical switch has been triggered, a first group in which the fault has arisen and the electromechanical switch that has been triggered is recharged by a second group without a fault through switching of an associated semiconductor switch, from among the associated semiconductor switches, that is arranged between the first group and the second group.
