>> 12 Co-creation The world’s energy consumption has increased immensely in recent decades. Between 1973 and 2007 world electricity demand rose by more than 300%. Expansion of the high voltage networks necessary to meet this demand has not kept pace with this extreme growth. Kendrion and Siemens are partnering to design solutions for this growing problem. Siemens’ 800-kilovolt extra-high-voltage direct current transformer. Joint brainpower: sparks fl y The increasing pressure on the existing high voltage transfer systems has led to considerably higher workloads, stability problems, higher thermal and mechanical requirements for net components such as wires and lines, generators, transformers and switches, and – last but not least – an increase in failures and blackouts. There are many things that can cause a high voltage power distribution system to fail: lightning strike, human error, overload or storm. But the result is always the same: short circuits that damage the wires and the network as a whole. In order to prevent this and limit the damage done to the absolute minimum, electricity companies require high-quality high voltage switches with extremely fast breaking times to minimise the risk of down time. >> More than just a supplier Gerald Puchner, Manager Research & Development at Kendrion Industrial Magnetic Systems, explains the partnership. ‘Siemens – a global player in the fi eld of high voltage power distribution – is constantly looking for the most effi cient and most powerful solenoids to put in their high voltage switch systems, to give them a unique selling proposition and competitive advantage. They needed a very fast trigger solenoid for their high and medium voltage circuit breaker. We have been selling electromagnets to Siemens for years and years, and this relationship has grown into a strong partnership. We obviously have the core competencies to be more than just a supplier, and are now working closely together with them – with Kendrion bringing in expertise and experience – to design a solution.’ >> Joint effort On the basis of co-creation, Kendrion and Siemens started researching options, with the goal of reducing actuator switching times for switching off a high voltage network in the event of emergency – by two-thirds. The Kendrion Design Engineer on the project was Markus Rekla. Kendrion presented four options, two of which did not fully meet the customer’s demands. After going back to the drawing board, Markus then came up with the idea of combining the principles of a very fast, dynamic solenoid and a standard solenoid: the hybrid electrodynamic actuator. >> Sharing information ‘We simulated the solution on the computer and developed a prototype that appeared to function as expected,’ Markus says. ‘We shared our information with Siemens and made a sample product for them, which also turned out to be successful. We are now in the process of starting the fi nal development and have applied for a patent on the product. A co-creation success story that is to be continued.’ annual magazine 2011
Real partnership Karl Mascher is Siemens’ Manager Basic Development of High Voltage Switch Systems. He is convinced that by mid-2012 the new hybrid electrodynamic actuator for Siemens will be available for delivery. ‘We are very happy with the result of our joint development of high speed actuators,’ he says. ‘It is a very innovative solution, in fact the only solution that enables us to realise these very fast breaking times. annual magazine 2011 We now have to convince our customers that this state-of-the-art solution also covers all their safety issues. We offer them a totally different approach to their switching problem, so that obviously takes some getting used to. Siemens and Kendrion have a valued long history together and our cooperation – which started in the 1990s, has always been very good. For this project we have kept each other informed on every single detail of Testing a high voltage Siemens circuit breaker with over one million times the breaking capacity of a household fuse. the development, from beginning to end. We didn’t just meet once, but formulated our assignment and waited for Kendrion to come back with a solution. This has been a real partnership. We are now considering developing a version for bigger and even more demanding applications, based on the same principle.’ >> 13
