The grid coupling contactor for GE® 1.5 MW turbines.
Pure shifting pleasure.
For years there have been reoccurring problems with circuit breakers used in wind technology. Apart from decreasing availability, frequent consequential damage to frequency converters or even fi res are always annoying for operators. Both cost a small fortune. Our grid-coupling con tactor remedies this situation and off ers an impressively quick return on investment.
Your antiannoyance system.

Overview of benefi ts:
• Considerable extension of service life of
circuit breaker
• Reduction of maintenance costs
• Permanently reliable connection and discon-
nection of grid-coupling contactor throughout
the service live of the WTG
• Prevention of consequential damage to the
converter and generator

In the same way as your success as an operator of WTGs depends on wind and weather, your WTGs must react reliably to these conditions. Thunderstorms and grid fl uctuations caused by weather conditions are only two of the occurrences that can considerably aff ect the grid. Overvoltages and undervoltages are often the result. In such situations, WTGs must reliably disconnect from the grid and reliably reconnect again at a later stage.
This task is carried out by the circuit breaker, carrying out some 2,500 to 3,000 switching operations each year. As its delicate mechanics are highly stressed during each operation, wear and the resulting maintenance are considerable. There is also the danger of thermal overloading and malfunctioning. Incorrect disconnect of the circuit breaker can cause expensive damage to the frequency converter.
Tה b� t so� � � : � vi� e work.
Teamwork for circuit breakers.
Our Availon grid-coupling contactor for GE® 1.5 WTGs divides
the existing task of the circuit breaker into two:
• The grid-coupling contactor handles most of the regular
switching operations of the system and has been designed
for 250,000 switching operations at the rated current
(mechanical life of fi ve million switching operations).
• The circuit breaker handles the overvoltage and under-
voltage protection. Its switching operations are therefore
on average reduced to a minimum of 20 to 30 per year.
Reduce stress, increase service life.It is a well known fact that by reducing stress, service life is increased. In case of the circuit switch, stress in parallel operation with our grid-coupling contactor is so low that you as the operator will save on most of the maintenance costs for this component. With up to 250,000 switching operations, our grid-coupling contactor has more than enough capacity to cover the entire service life of your WTG. A positive side eff ect: as faults on the grid-coupling contactor and on the circuit breaker history, the availability of your WTGs will also increase considerably.
