Siemens 3AV1 Blue LT Circuit Breaker
Zero harm means
Zero SF6
As the energy industry continues to strive for Net Zero, it is essential to achieve Zero Global Warming Potential (GWP) in the transmission of power as well as in its generation.
That means the elimination of climate-hostile fluorinated gases (F-gases) from electrical switchgear – especially SF6.
Recent EU legislation has restricted the use of these gases, with a full ban likely in the near future. Clean air insulation with vacuum switching technology is the way forward, since this involves Zero greenhouse gases of any kind and has Zero harmful impact on the environment.
The clean air technology used in the Siemens Energy Blue portfolio is well proven and already in operation worldwide – with the 3AV1 Blue live tank being a prime example of how using Zero F-gases means Zero compromise on performance.
Extensive experience
The technology is long established. We have 40 years of experience in producing medium-voltage vacuum interrupters suitable for power networks up to 52 kV, and this capability has been extended to the high-voltage 145 kV level.
Prototypes of these breakers began to operate on a number of sites in 2010, and the 3AV1 model has been in production since 2017 with more than 150 units delivered worldwide.
Like all our circuit breakers, the 3AV1 LT is designed using a tried and tested modular platform concept. The operating mecha-nism, control system, base frame, kinematic chain and insulator designs are based on decades of manufacturing and operating experience.
High-voltage, high-performing vacuum technology
The 3AV1 delivers the high levels of performance and reliability our customers have come to expect from our circuit breakers:
• Reliable making and breaking capabilities
• 30 full short-circuit current interruptions
• 10,000 rated current interruptions
• Optional 2-cycle current interruption
• Full performance down to -60° C ambient temperature
• Zero-maintenance interrupter unit (full lifetime)
• Tested in accordance with IEC 62271-100, 110, -310
With Zero F-gases and Zero compromise on performance, the 3AV1 Blue Live Tank circuit breaker is helping to make a greener grid achievable.
