LD

¡Feliz cumpleaños!

¡El sistema LD es el resultado de 50 años de experiencia en busbar de alto voltaje! Nacido y probado como sistema ventilado por aire, LD ha suministrado alto voltaje de forma fiable a muchas aplicaciones durante décadas. Nuestro sistam no ha cambiado mucho en el exterior - se ha mantenido delgado y su alta valuación en el tema de corto-circuitos ha inspirado generaciones. LD nos ha abierto el camino  para esarrollos más avanzados como los sistemas LDM y LDM-P.

¡Tu también deberías confiar en un sistema comprobado que se está reinventando constantemente!

Busbar en lugar de cables

El sistema SIVACON 8PS - LDM para la transmisión de energías renovables

Los sistemas troncales SIVACON 8PS busbar con sistemas LD y LDM se han utilizado con éxito en turbinas eólicas durante varios años. Ahora se ha unido también el sistema troncal LDM-P a la familia. Este sistema está destinado para uso en estaciones fotovoltáicas y de contenedores, donde de transmiten energías extremadamente altas en muy poco espacio.

SIVACON 8PS - LDM system for windturbines

El sistema LDM ofrece diferentes ventajas según especificaciónes de diseño -  para inversores, operadores de campos eólicos diseñadores de turbinas eólicas o fabricantes de torres - y sin extra coste. Estos beneficios son por ejemplo  disponibilidad mejorada y/o más seguridad y fiabilidad durante instalación y operación. El sistema troncal LDM busbar de la familia de productos SIVACON 8PS es la alternativa innovadora a los cables. El sistema LDM ofrece fiable y eficiente transmisión de energía para correintes hasta 8.200 A.

SIVACON 8PS - LDM system: cost-efficient planning

The LDM system precisely fulfils the specific needs and requirements of every wind turbine and provides all the necessary components, significantly simplifying system planning. This enables, for example, the rotor and stator runs for double-fed asynchronous generators to be routed within a single housing. A PE conductor can be optionally included in the same routing. What’s more, specialists on Siemens' Wind Power team are there to provide you with expert advice and to support your planning efforts. Hence, you can plan cost-efficiently right from the project start.

SIVACON 8PS - LDM system: efficient installation

Simply join the segments, secure with bolts, and you're done: LDM busbar trunking systems arrive at the project site in pre-assembled segments. Contrary to cables, there's no need for complex cutting to length, stripping, insulating, and screwing into place. All the busbar needs is a support on the tower wall every 3.20 metres. Compare this to cable systems, where spacing must be calculated, with some intervals less than 50 cm. 

 

In addition, busbar elements can be pre-assembled and installed in tower segments that lie horizontally prior to final erection, thereby saving time and money. On site, all that's left to do is secure the connections between the tower segments during final erection using design verified single-bolt connections. The assembly work in all phases of installation is performed using a standard torque wrench. In short: Using the LDM system substantially reduces installation time.

SIVACON 8PS - LDM system: safe and reliable operation

The LDM busbar trunking system transmits power from the nacelle to the tower base safely and reliably. The LDM system meets all requirements of IEC 61439 Parts 1 and 6. This means that the system is subject to priordesign verification, ensures that all technical parameters are sustainably fulfilled, and rules out any overloading of the systems and consequential damage. Any short circuits arising have no impact on the LDM system. Because practically no plastics are used, the fire load is very low, immensely increasing the level of safety compared to cable systems. For wind turbine operators, this translates into reliable wind farm operation – across the entire fleet.

SIVACON 8PS - LDM system: working sustainably

Growing importance is being place on improving the energy efficiency of wind power. Manufacturers and operators of wind turbines are coming under pressure to design their units to be as low-loss as possible. With LDM system, Siemens has developed a system that minimises power losses and significantly improves efficiency. 

 

Over the total service life of a wind turbine, this translates into additional grid feed-in compensation for wind turbine operators. In addition to the quick return on investment, operators using the LDM busbar trunking system demonstrate their sense of responsibility for environmental issues – thanks to the environmentally friendly, halogen-free design, high energy efficiency, and high recycling rate.

SIVACON 8PS - LDM-P system for photovoltaic and container stations

The benefits of the technology over cable-based solutions are particularly apparent in photovoltaic and container stations. These include fast planning and installation, current intensities up to 7,000 amperes (A), and exact adaptation to other necessary products, such as inverters and transformers. Siemens also provides comprehensive support during the planning phase and enables the customer to achieve integrated and thus very efficient power distribution.
