6 FAQs about [Energy storage circuit fuse]
Why do energy storage systems need special fuse inserts?
More energy storage systems are installed globally every day. Present-day battery systems often reach power outputs of several hundred MWh. That requires advanced protection using special fuse inserts. They have to dramatically reduce the current in response to a short circuit and interrupt it very quickly as well.
What is a power fuse?
Fuses are safety devices used in an electric plug or circuit, made of a wire component inserted in a non-combustible housing. The main function of a power fuse is to prevent the damages induced by an overflow of electrical current.
Why do batteries need fuses?
Modern-day battery and energy storage systems place huge demands on fuses. Constantly rising power levels at maximum DC voltages of 1500 V can generate short-circuit currents of several hundred kiloamperes. Another issue relates to load profiles produced by a wide variety of loading and unloading cycles.
How does a fuse protect an electrical circuit?
A fuse is a thin piece of metal that protects an electrical circuit. If the current flowing through the circuit exceeds the fuse's capacity, the fuse heats up and melts, opening a gap in the circuit and stopping the flow of electricity. This prevents the more expensive components in the circuit from melting.
What is a SIBA fuse?
SIBA has decades of experience with fuse solutions for power electronics and rail traction systems. It thus has the ability to effectively protect complex interactions between battery and mains circuits. The new fuse inserts have been tested for a rated breaking capacity in excess of 100 kA and are available in various body types. Any questions?
What is a VDE 0636-7 fuse insert?
They have to dramatically reduce the current in response to a short circuit and interrupt it very quickly as well. To address this need, national (DKE) and international (IEC) standard-setting committees have agreed on a new standard for fuse inserts to protect battery systems: VDE 0636-7 (IEC 60269-7).
