[0038] The fast charging device for the valve chamber in this embodiment rectifies the alternating current of a single-phase generator into direct current with a rated voltage of 24V to charge the 24V battery pack in the valve chamber.

The National Pipeline Network Corporation has many valve chambers under its jurisdiction, which are distributed across oil and gas pipeline stations across the country. The power supply batteries are all 24V power supplies, and the application prospect is wide.
