Introduction to storage battery
The battery pack is an independent and reliable operating power source. It is not affected by the AC power source. It can still ensure continuous and reliable operation even in the case of a power outage and a busbar short-circuit in the whole plant.
The battery voltage is stable and the capacity is large. It is not only suitable for various more complicated relay protection and automatic devices, but also suitable for the transmission of various circuit breakers. Therefore, the large-scale enterprise substation usually uses the battery pack as the operating power source, but the battery pack Operating power supply requires many auxiliary equipment and special rooms, with large investment, short life, long construction time, complicated operation, and heavy maintenance workload. Therefore, battery packs are generally not used as operating power supplies in small and medium-sized substations, and rectified DC are mostly used. Operating power or AC operating power.
