WIN! With its cutting-edge and secure solutions for the harsh environment of wind power installations, Weidmüller is continually contributing to the competitiveness of wind applications throughout the world. What sets the new lighting system apart?
Schlingmann: Up until now, linear fluorescent luminaires were often used to provide interior lighting in wind power installations. Compared with LED technology, linear fluorescent luminaires harbour a wealth of disadvantages during ongoing plant operation.In addition to their high power consumption, they are also very fragile and often result in unnecessary additional costs for maintenance and replacement. It certainly isn't uncommon for the actual installation and maintenance work to be preceded by unscheduled servicing, as it is simply impossible to work safely in the towers without sufficient interior lighting.
In contrast, LED lamps are especially energy-efficient and boast a service life of up to 20 years.
In developing our FieldPower® LED lamps, we have designed every detail to meet the extreme environmental conditions in wind power installations.
WIN! What specific characteristics distinguish the lighting solution as particularly practical?
We have developed two variants to cater to the particular requirements of the different areas in a wind power installation. Given its non-directional light incidence, the FieldPower® MONO LED is excellently suited to illuminating large spaces and work areas in
The wide-range input from 24 to 120 V DC enables illumination of large distances – in the tower of a wind power installation, for example. Even from a low conductor cross-section of 1.5 mm², up to 40 FieldPower® LED lamps can be supplied over a length of up to 230 m. Compared with the systems on offer at present, the use of a centralised, uninterruptible 24 V DC power supply minimises costs ranging from procurement and servicing to ongoing operation.
The entire circle of light can be monitored remotely when needed, making service operations more efficient and thus cutting costs. Also a luminous signal
can be triggered by the circle of light to visually warn service staff when there are problems in the plant. At the moment, acoustic warning systems are used, but these can very quickly be drowned out by ambient noises.
To sum up, our unique combination of LED technology, application-specific power supply, automation and individual system design opens up fresh potential for optimising the efficiency in the illumination of wind turbines – for enlightening arguments from planning to operation.
