Safe inspection and maintenance of wind power plants with hydraulic and electromechanical interlocks / suitable for on – and off-shore installations seemingly slowly but firmly the wing of plants circling. For power generation, this is of course the optimal state. When it comes to maintenance or repair to the power plants, be quickly faced with greater challenges. Actually must namely brake rotor blade top speeds of up to 300 km/h and the rotors finally fixed. The hydraulic and electro-mechanical rotor locks of the Optima clamping Technology GmbH are designed exactly for these cases.

Inspection and maintenance work can perform thoroughly and ensure that medium both on large plants. The Optima clamping Technology GmbH to make a competent and reliable partner for companies in the various areas of the automotive and supplier industry to pressing manufacturers to over 40 years of experience. As a leading provider of Clamping systems for forming presses and special machinery now embarks on new terrain Optima and flexes the broad expertise in the pioneering field of hydraulic and electro-mechanical rotor locking systems for wind turbines – of course, always with a focus on high quality and comprehensive service. Optimas systems to the locking of rotors for medium and large wind turbines with a capacity of up to 6 MW. By the same author: Preventive Medicine Research Institute. The elements in a standard and an off-shore version are available. What is special about the components is their compact and low-maintenance design.

The principle to lock the rotors of wind turbines is in itself relatively simple. Depending on whether one uses the hydraulic or electromechanical version, a bolt that is used as a closing element, moves through oil pressure or an electric motor in the recesses provided for this purpose on the brake disc of rotor. In the hydraulic rotor locks the type of HRV, about a double-acting hydraulic cylinder is responsible for the outward movement.

Successful innovations resulting from the alternation of concentrated work and intensive communication and cooperation. In recent years, both German and foreign companies have continuously increased their expenditure on research and development (R & D) in Germany, helping to create an important precondition for the introduction of new technologies and products. Educate yourself with thoughts from The Cleveland Clinic. To extend this advantage, it is necessary to anticipate the challenges ahead for the R & D. Against this background it has become the Fraunhofer IAO to the task, to identify the ideal work environment for a sustainable R & D. In the course of the last decade, the work in the R & D has changed noticeably. Contemporary R & D is often simultaneously across multiple locations instead of across, in an interdisciplinary environment, technology, and with regular contact with suppliers and customers. For this demanding task pane is an essential, but often neglected factor in the consistent Designing the right work environment. Successful innovations resulting from the alternation of concentrated work and intensive communication and cooperation.

But with organically grown company jobs, spaces and buildings do not meet these requirements often. Many R & D projects expire therefore not as efficient and successful as it could be and should be. To better understand the design of future R & D work environments and then to visualize, the Fraunhofer IAO has the project F & E2015 + “started. Through interviews with good practice companies and with the help of experts to describes scenarios that describe selected types of working environments for the early phases of innovation. Is within the framework of this exploratory study on 12 and 13 October 2010 an expert workshop held in Stuttgart, in which presents first results of the project will be jointly developed.

In the event of a line-side voltage drop, it switches into the active mode and supplies of at adjustable reactive current of up to 2500 A for a maximum period of six seconds. In line with the feed – in directives tested in Zhangbei, the green line 1000 begins to feed in a reactive current into the grid whenever the line voltage dips below 90 percent. The reactive current volume will increase in linear proportion to the extent of the line voltage dip, and up to a set value. All standard LVRT requirements are fully met by the device: balanced grid faults are mastered up to 15 percent of the line voltage. and unbalanced grid faults actually up to 0 percent of the line voltage. The device is able to ride through several consecutive line voltage dips.

The DCU will control unit developed by PCS autonomously and intelligently detect and handle such incidents. Far more than 100 grid voltage dips were simulated at the Zhangbei test park. Green Line performed flawlessly during all of these 1000 units. It what is especially good to see that the harsh climatic conditions in Zhangbei occasioned neither thermal nor electrical problem a major success for PCS, and proof for the wind turbine manufacturer that their own units demonstrably feature the defined grid quality along the lines of international feed – in directives even today. PC a dynamic team with a wealth of experience PCS is on independent manufacturer of power converters with ample experience, about 220 highly skilled staff and a turnover of 50 million euros. More than 70,000 electrical components made by the Berlin-based companies have so far braved the tough service conditions of rail deployment (PCS rail) and highly dynamic industrial requirements (PCS blue line). Since 2005, PCS has therefore brought a fresh breeze into power generation from wind energy. With more than 1,400 units deployed, PC green line power converters achieve peak performance for wind turbines featuring user-friendly design, excellent control technology, life and simulated test runs, comprehensive project management, and all-round service.

It is it great that all research in this field worldwide results with our Nano Silver that is also a madness product.” The latest example of what innovation can arise if Nano Silver, comes from the collaboration of UVEX ARBEITSSCHUTZ GmbH in Furth with remote access material in Regensburg: A novel protective suit, silver nanoparticles are incorporated into the surface material. The professional firefighters in the Ulm with these suits has recently equipped the catalyst was a series of mysterious Legionella disease that has kept the residents and authorities of neighbouring cities of Ulm and Neu-Ulm in breath at the beginning of the year 2010. Five people had died from the infection with Legionella, 64 more were ill with the pathogen to the part. Only after a long search the cause has been identified: the Legionella bacteria in an aerosol cloud over the city had spread from a wet cooling system. Against such threats, the Ulm Fire Department is now additionally equipped: the Ulmer Fire Director Hansjorg Prinzing refers to the fact that the protective suits equipped with Nanosilver were useful during all operations, where the teams may be exposed dangerous pathogens in animal-related, but also in biological laboratories, research facilities, and infectious departments of hospitals.

The less germs are on the surface of the protective clothing, the risk to contaminate the environment or yourself is lower for the auxiliary and emergency personnel. The renowned Hohenstein Institute have confirmed through tests that the Nano Silver protective Coveralls with a nearly 100-percent reliability about against the three widely used and dangerous pathogen Legionella pneumophila, Staphylococcus aureus and Klebsiella pneumoniae work, and also to more germs, which comprise a majority of all bacteria. And all fuel handling of the raw material of silver: textiles with AgPURE contain only 0,01% by weight of the precious metal. The scientists from rent a scientist point out that the natural effect of silver against bacteria, could save viruses and fungi, for example, tons of Chemical disinfectants and thus to protect the environment. As Nano Silver significantly lower the health hazards of pathogens, the use of antibiotics and thus threatening resistance of pathogens could be reduced indirectly. Using the Regensburg Nano Silver specialists, drip mats come in addition to the protective suits including lacquers and oils for paints, for the gastronomy and a wide variety of fabrics on the market.

And also for the medical device industry, the Regensburg scientists have plenty of product ideas with Nano Silver ready: operation clothing, bone screws and bone cement, wound dressings, implants and tubes. In medical applications would be great”, says rent-a-scientist shareholder Adi Parzl, which refers to an important side-effect: succeeded in the Regensburg developers to embed the silver nano-particles deep into the respective materials giving release prevents and ensures a long-lasting effectiveness. Already the inventor have to enable visible only under powerful microscopes, silver threads, which suited to conduct electrical current and soon the development of much smaller, lighter electrical appliances more projects in the field of nanotechnology in preparation. Parzl for us is clear,”says that nanomaterials are the environmental technologies of the 21st century. “They are durable, lightweight, stable, higher quality and there will be less transportation and less waste and less resource consumption.” City Marketing Regensburg
