LLDG new energy vehicle charging pile transformer

DG series single-phase isolation transformer is suitable for AC 50Hz-60Hz, rated power supply voltage does not exceed 500V AC circuit, input and output windings with electrical isolation, to avoid accidental contact with live body at the same time. In addition, the high frequency loss of the core can be used to suppress the high frequency clutter into the control loop. The isolation transformer is used to make the secondary to ground suspension, which can only be used in the situation of small power supply area and short circuit. At this point, the system's capacitance current to the ground is too small to cause harm to the human body. It can work effectively in the rated load for a long time, with excellent performance, reliable work and safe wiring; All kinds of input and output voltages, distribution of tap line capacity, can be carefully designed and manufactured according to the requirements of users.

  • Product details advantages:

    1. The windings are made of class H enameled copper/aluminum wire, which can withstand temperature up to 180 ° C, is well insulated and durable.

    2. New high-quality cold-rolled silicon steel core (oriented and non-oriented optional) , good heat dissipation, low core loss;

    3. The transformer whole H class insulation varnish vacuum impregnation, has the extremely high heat resistance, and anti-corrosion, the running noise is low, the insulation performance is good.



    this series of single-phase transformer is widely used in CNC machine tools and mechanical equipment, elevator control cabinet, lighting and signal lamp power supply, also can be used as a small power supply.



    1. Suppression of harmonic interference;

    2. Increase the system impedance, so that the protection device is easy to fit;

    3. Reduce the impact on system voltage when starting heavy-duty equipment.

    4. When isolated transformer load side occurs single-phase earthing, will not cause the whole system single-phase earthing;

    5. When a short-circuit accident occurs on the load side, the short-circuit current of the system is limited.
