The smart energy box transformer (DC DC-DC) independently developed and produced by Jiangsu Zhongmeng Electric is a system power station that provides DC power for charging. It is a charging pile specific smart box transformer that connects 10kV three-phase AC power from the power grid to the primary of a phase-shifting transformer, and outputs 282Vac, 24 pulse AC power with four windings in the secondary output. Two sets are connected in series and then sent to the rectifier for output. The DC power supply with voltage Udc=720V and current dc=1528A is used for the DC/DC power module of the charging pile.
1. Digitization: With a high degree of digitization, it can be remotely monitored and display real-time data such as voltage, current, power, temperature, and fault status.
2. DC power supply: It can provide DC power to ensure the charging needs of new energy vehicles.
3. Protection function: There are high and low voltage equipment and components in the transformer box, which require high safety. The smart transformer box has been optimized to address these issues, with more comprehensive protection functions and higher safety.
4. Remote billing: The transformer can be remotely billed and charged according to the user's needs.
5. Cost reduction: Smart box transformers can be unmanned, automatically detected and maintained, reducing labor costs.
6. Small size: The box transformer has a small volume and can be placed in residential areas without affecting the environment.
7. Cost reduction: Box type transformers have a higher cost but a longer service life, which can reduce users' operating costs.
