The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the segmentation fault has a large current (excessive current will melt the
Energy storage is well positioned to help support this need, providing a reliable and flexible form of electricity supply that can underpin the energy transformation of the future.
