Introduction to the iron core of DC charging pile transformer

The transformer core of a DC charging pile is a critical component responsible for establishing the magnetic circuit and transferring energy. Here is a detailed introduction to the six key characteristics and components of the transformer core:

Main component

Structure of the Core Body

The core body of the transformer in a DC charging pile is typically made up of laminated silicon steel sheets, which help reduce magnetic hysteresis losses and eddy current losses, thereby improving the efficiency of the transformer. The arrangement and stacking method of the silicon steel sheets directly affect the performance of the transformer.

Diverse Material Options

The transformer cores come in a variety of materials, including oriented silicon steel, soft magnetic ferrite, amorphous alloys, and nanocrystalline alloys. These materials, based on their magnetic properties and frequency response characteristics, are suitable for transformers used in different frequency applications, meeting the needs of DC charging piles in various scenarios.

Unique Structural Form

The core consists of a core limb and a yoke. The core limb has windings wrapped around it, and the yoke connects the core limbs to form a closed magnetic circuit. This structural design helps improve the efficiency and uniformity of magnetic flux, reducing energy loss.

Importance of Insulation Components

Insulation components provide electrical isolation between the core and the windings, preventing short circuits and ensuring the safe operation of the transformer. The performance of the insulation components directly affects the reliability and lifespan of the transformer.

Role of Grounding Plates

Grounding plates ground the non-magnetic parts of the core to reduce eddy current losses and improve the efficiency of the transformer. Proper grounding is crucial for the stable operation of the transformer.

Functions of Auxiliary Components

Supporting blocks and fasteners are auxiliary components used to support the core, reduce vibration and noise, and fix the core to the transformer frame. Cooling systems and protective devices are responsible for controlling the temperature of the core and monitoring its operating status, ensuring the safety and stability of the transformer under various conditions.

In summary, the transformer core of a DC charging pile is a complex system, and its design and material selection have a decisive impact on the performance of the entire charging pile. Through careful design and material optimization, the efficiency and stable operation of the transformer in the DC charging pile can be ensured.

DC CHARGING PIlE SERIES

DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
