An anchoring unit for a system, the anchoring unit having at least one first insulation layer and at least one second insulation layer. The anchoring unit furthermore includes a support layer for mechanically stabilising the insulation layers, the support layer being arranged between the first insulation layer and second insulation layer. The anchoring unit furthermore includes at least two screws, the screws being oriented in opposition to one another, a first screw being suitable for anchoring to the system and a second screw being suitable for anchoring to an anchor object. A first screw head of the first screw is in direct contact with the support layer. A screw shank of the first screw is arranged at least partially in the first insulation layer. A method includes fastening a system to the anchoring unit.

Anchoring unit, method for fastening a system to an anchoring unit, and system unit with anchoring unit

A circuit arrangement and to a method for operating the circuit arrangement, particularly a circuit arrangement for the DC power supply of a plurality of parallel electrolysers, where the circuit arrangement has a rectifier which converts an input-side alternating voltage into an output-side first DC voltage. Each electrolyser is respectively connected in parallel to the output of the rectifier by a down converter converting the first DC voltage into a second DC voltage such that the second DC voltage drops over the electrolyser. Each of the down converters is controllable and/or regulatable in order to adapt the level of the second direct voltage.

Circuit arrangement for supplying current to an electrolysis device and a method for operating the circuit arrangement

A method for generating an inductive reactive power for a public grid by an electrical load apparatus, in which, in a first operating mode of the electrical load apparatus, an alternating current of the public grid is transformed by a transformer device and the transformed alternating current is provided for an electrical load of the electrical load apparatus. In a second operating mode of the electrical load apparatus that is different from the first operating mode, the transformer device is short-circuited in a phase-controlled manner by a switching device of the electrical load apparatus, wherein the switching device is phase-controlled such that, depending on a phase angle of the phase control of the switching device by the transformed alternating current, the inductive reactive power for the public grid is generated by the switching device.

A circuit assembly includes at least one coil assembly with a first coil and a second coil, the first coil being connected to a DC voltage side of a rectifier of the circuit assembly, and the second coil being connected to a power source of the circuit assembly, the first coil and the second coil being coupled to each other via a coupling component of the coil assembly, the coupling component forming a core of each of the coils.

Circuit assembly, electrolysis device, and method for operating a circuit assembly or an electrolysis device

An electrolysis unit and to a method for electrochemically decomposing water into hydrogen and oxygen. The electrolysis unit has at least two electrolysis modules. The electrolysis unit also has exactly one first gas separation device for a first product gas including oxygen and exactly one second gas separation device for a second product gas including hydrogen. The first gas separation device is connected to the at least two electrolysis modules by respective first lines. The second gas separation device is connected to the at least two electrolysis modules by respective second lines. The at least two first lines have the same first length. The at least two second lines likewise have the same second length.
