Can be connected to the power grid as an independent system, and can play the role of peak shaving and valley reactive power compensation for the power grid. The battery can convert excess AC into direct current for storage, and then convert it into alternating current for discharge when the power is insufficient, and the charging and discharging processes need to be protected.
The Non-polarity miniature circuit breaker can realize bidirectional protection for cable. By changing the distance between the dynamic and static contacts and increasing the method of the arc ignition coil, the arc can smoothly enter the arc extinguishing chamber, thereby cutting off the fault. In addition, an AC distribution box is required to meet the requirements of the power distribution system.
