Publication number: 20100208768Abstract: A temperature monitoring apparatus for high-voltage or medium-voltage components has a transducer which can produce a mechanical signal, which is dependent on the temperature of the component to be monitored. The mechanical signal is transmitted to an electrically isolating transmission element, for example in the form of a rod, and from the transmission element to a movement sensor. The transmission element can be arranged in an electrically isolating hollow body. This arrangement allows the movement sensor to be isolated from high voltages.

Publication number: 20080049384Abstract: A cooling device is disclosed for an electrical operating means, which has a surface to be cooled. The cooling device comprises a coolant, a peripheral wall, whose interior defines a volume for the coolant, a fastening for fastening the cooling device to the electrical operating means, and a contact-pressure means. The peripheral wall has a thermally conductive contact wall with a contact face, which is designed for areal contact with the surface to be cooled.

Publication number: 20080022683Abstract: Because the efficiency of the thermal energy storage technology is inherently restricted, its beneficial use is limited to very particular economic boundary conditions, i.e. a large difference between the value of electricity going into the unit and the value of electricity coming out of the unit. With the reduction in wind power equipment prices and the cost of fossil fuels and/or their combustion products this is occasionally the case for wind power. Wind is a free fuel and the value of wind power when there is too little load demand is essentially zero, and the value of wind power when there is demand is considerable indeed. Under these circumstances, a combination of electrothermal energy storage and combustion of (fossil) fuels as an auxiliary heat source provides for a cost efficient system for storing energy and an economical way of generating electricity.Type: ApplicationFiled: March 10, 2005Publication date: January 31, 2008Inventors: Christian Ohler, Daniel Chartouni, Martin Lakner

Publication number: 20050150643Abstract: The present invention provides a fluid-to-fluid through-the-wall heat exchanger for condensation of a vapour in a primary fluid stream, wherein a flow path (5) of the primary fluid stream is defined by an inner cylinder (1), an outer cylinder (2) arranged concentrically to and surrounding the inner cylinder, and a helical space holder (3) arranged between the inner and the outer cylinder. Additionally, the cylinder surfaces delimiting the primary flow path are made of or coated with corrosion resistant material in order to reduce a contamination of the primary fluid. Compared to other condensers with identical ratings, this heat exchanger shows a smaller flow resistance, resulting in a smaller power demand of the blower or pumps, It is therefore particularly suitable for fuel cell systems where the condensed water has to be recirculated in the system and where purity demands are high and parasitic blower power should be minimal.Type: ApplicationFiled: June 18, 2003Publication date: July 14, 2005Inventors: Daniel Chartouni, Eric Killer, Christian Ohler
