The disclosure relates to a wiring configuration for a stator of an electric machine. The wiring configuration comprises a busbar which forms a segment of a switching ring with an outer connection and a winding connection. Outer connection elements and winding connection elements are arranged in a wiring region. The wiring configuration additionally comprises a receiving element which is at least thermally coupled to the busbar. The receiving element is arranged outside of the wiring region. The disclosure additionally relates to a temperature sensor device for plugging onto the receiving element of the wiring configuration and to a system for detecting the temperature of a stator.

An electric machine has a plurality of phases. A winding is associated with each phase. An interconnection arrangement includes an annular carrier element with a plurality of axial cutouts, each for passage of a portion of a winding and a plurality of concentrically arranged, hollow-cylindrical switching rings. Each switching ring is adapted to contact a winding. The carrier element and the switching rings are adapted to radially positively engage one inside the other in an axial contact zone.

A stator of an electric machine includes a stator winding having a plurality of coils, the coils are connected to one another by connection conductors. A temperature sensor is arranged at a connection conductor and is in thermal contact with the connection conductor for detecting a temperature. Two parallel current paths are formed at the connection conductor and the temperature sensor is arranged at one of the current paths.

A method for operating a controllable electrical device connected by a data link to a control device for controlling the electrical device, includes using the electrical device to exchange electrical power with a connected electrical grid and using an environmental sensor for collecting environmental information. The control device transmits control signals to the electrical device over the data link. The electrical device assumes a first or a second operating state depending on the control signals transmitted. The electrical device exchanges energy with the electrical grid in the first operating state and the electrical device does not exchange energy with the electrical grid in the second operating state. Environmental information collected by the environmental sensor is transmitted over the data link to the control device only when the electrical device is in the second operating state. An assembly for carrying out the method is also provided.

An electrical component includes a conductor having a plurality of conductor sections. The conductor sections are electrically short-circuited. The short circuit is at least partially eliminated when the temperature of the component exceeds a threshold or limit value. An electrical circuit including the component and a method for increasing the inductance of an electrical component having a conductor, are also provided.

Electrical component

A power module for a converter, in particular for a multilevel converter. The power module includes a link circuit capacitor, two connection terminals, at least one half-bridge connected in parallel with the link circuit capacitor and having two semiconductor switches, and, for each half-bridge, a bypass diode connected in parallel with a first semiconductor switch of the half-bridge and a load-relief circuit group connected in parallel with the first semiconductor switch. The load-relief circuit group has a load-relief thyristor and a load-relief diode connected in series with the load-relief thyristor.

An electrical configuration contains at least one submodule which has a first and a second outer electrical terminal. The configuration further has a bypass switching device, which is electrically connected between the first and second terminals and in the on-state causes an electrical short-circuit in at least one current flow direction between the two outer terminals. The bypass switching device has a thyristor with an anode terminal, a cathode terminal and a trigger terminal and is connected by its anode terminal to one of the two outer terminals and by its cathode terminal to the other of the two outer terminals. A triggering device is connected to the trigger terminal of the thyristor for triggering the thyristor, and a switch is provided which in the on-state connects the anode terminal of the thyristor to the trigger terminal of the thyristor.

Submodule and electrical arrangement having submodules

A method protects an electrical modular unit from overcurrent damage by virtue of an inductive component converting electrical energy into magnetic and thermal energy, in which a bypass bypasses the inductive component during regular operation of the modular unit and current flows via the bypass. In order to reduce current spikes in the event of a surge current without significantly enlarging the semiconductor switching the circuit inductance for the commutation circuit, it is proposed that the bypass is opened by an overcurrent flowing through the bypass which is above a current value that can be achieved during fault-free operation of the modular unit, with the result that more current is forced through the inductive component than residual current flows through the bypass.

An electric energy storage device which is connected to an electronic circuit is discharged by way of a first and a second electric conductor. A thyristor is provided for discharging the energy storage device. As a result of a fault occurring in the electronic circuit, a discharge current of the energy storage device begins to flow from the energy storage device to the electronic circuit via the first electric conductor and back to the energy storage device via the second electric conductor. The discharge current causes a magnetic field which changes over time to be generated about the first electric conductor and the second electric conductor. The magnetic field penetrates the semiconductor material of the thyristor. By virtue of the temporally varying magnetic field, a current is induced in the semiconductor material of the thyristor, and the thyristor is activated by the induced current.
