Siemens at the Hannover Messe 2015: Hall 9, Booth D35
Siemens have expanded their portfolio of switch disconnectors for low-voltage power distribution. The new devices from the 3KD series were developed specifically for personal and system protection in photovoltaic plants and wind farms.
The new six-pole model switch disconnectors are designed for PV systems in which high voltages up to 1200 V (DC) are generated. Siemens increased the permissible AC operating voltage tolerance of the three- and four-pole units from previously +5% to +10% as required by the IEC 60947 standard for wind farms.
The 3KD switch disconnectors will now safely power down systems with voltages of 690 V AC (+10%). Siemens offers the units with integrated side wall-mounted rotary operator for left- or right-hand side mounting.
Switch disconnectors ensure the safe activation and deactivation of electric equipment under load. They are used as repair switches to safely disconnect power and ensure secure conditions for maintenance work. As emergency stop switches, they protect machine operators against electric shock in case of faults. The 3KD switch disconnectors are suitable for currents up to 1600 A and are designed for use in buildings, factories, wind farms, and PV systems.
They are easily mounted and quickly commissioned. The modular design and comprehensive range of accessories allows the addition of further functions easily via retrofits. Additional safety features, including terminal covers, prevent direct contact with live components at the switch disconnectors. The contact setting of the switch is easily visible via the transparent terminal covers, which prevents incorrect operation. The devices are lockable, which offers additional protection against unauthorized switching. Plug-in phase barriers protect against inter-phase arcing.
An extensive service and support offering rounds off the engineering of the 3KD switch disconnector: Eleven CAx data types for mechanical and electric planning are made available for download online, including internal circuit diagrams, connection diagrams, dimensional drawings, and 3D models. The information can be downloaded via the CAx Download Manager. The data can be quickly and flexibly bundled, and then integrated in any popular configuring tool.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
