New Switch Disconnector Protects PV and Wind Turbine Systems

16.03.2015

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 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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
