Abstract: A motor vehicle has a pressure relief device that can be thermally activated, for the pressure relief of at least one pressure vessel. A body floor element is arranged at least partially between the passenger compartment or the cargo area and the pressure vessel. A pressure relief triggering device is designed to directly or indirectly bring about the pressure relief. The pressure relief triggering device is designed to absorb thermal energy from the passenger compartment or the cargo area in order to trigger the pressure relief device, without the thermal energy absorbed for the triggering having previously been transmitted to the pressure relief triggering device through the body floor element.

Abstract: A method is provided for producing a pressure vessel from a metal liner, which is reinforced at an outer lateral surface thereof by fiber composite material having a resin matrix. In at least one production step, the resin matrix of the fiber composite material is subjected to an ultrasound treatment.

Abstract: An arrangement having a first group of rectifiers, which form a series circuit on the DC voltage side and which can be connected to a first AC voltage network, and having a reserve rectifier that, in the event of a fault in one of the rectifiers, can be electrically connected by suitable switching apparatuses to the first AC voltage network and on the DC voltage side to a first DC voltage line to form an augmented series circuit with the rectifiers. An installation for transmitting electric power between at least one first wind farm with at least one wind power installation and the first power supply system, including the first group of rectifiers, is able to be connected to the first wind farm via the first AC voltage network.

Abstract: A method produces a pressure vessel having at least one fiber-reinforced layer. The reinforcing fibers of the fiber-reinforced layer are formed of at least one endless fiber. The modulus of elasticity of the at least one endless fiber is varied.

Abstract: A pressure vessel for storing fuel is provided. The pressure vessel includes a liner for storing fuel, a fiber-reinforced layer which surrounds the liner at least in regions, and at least one load ring. Connecting pins project from the surface of the load ring, and the connecting pins protrude out of the fiber-reinforced layer. A motor vehicle including such a pressure vessel and a production method for the pressure vessel are also provided.

Abstract: A pressure vessel for storing fuel includes a liner for storing the fuel, a fiber-reinforced layer that surrounds at least some areas of the liner, and at least one domed cap which at least partially covers an end of the liner. Connection pins project from the surface of the domed cap. The connection pins protrude from the fiber-reinforced layer.

Abstract: A power generation facility includes at least one generator which has a converter on the generator side and a converter on the network side and which is connected by the converters to an alternating voltage network on the power plant side. A rectifier connects the alternating voltage network on the power plant side to a DC transmission line. An inverter on the energy network side connects the DC transmission line to an energy network operating on the basis of alternating voltage. A control unit is configured to control the converter on the generator side and the converter on the network side of the at least one generator, at least on the basis of DC current and/or DC voltage measurement values measured on the DC transmission line. A method for operating a power generation facility is also provided.
