300 Kva Casting Resin Dry Type Step Up Transformer

The 300 kva casting resin dry type step up transformer is based on the principle of electromagnetic induction and is a power equipment specifically designed to convert the input low voltage alternating current into the same frequency but higher voltage alternating current. It is widely used in scenarios such as power transmission in power plants, grid connection of photovoltaic or wind power new energy sources, and power supply for industrial high voltage equipment.

The 300 kva casting resin dry type step up transformer’s primary winding on the input side has fewer turns and the wires are relatively thicker. One end is connected to a low voltage AC power source, which is the core component for receiving external low voltage electrical energy and generating an alternating magnetic field.

The secondary winding on the output side has far more turns than the primary winding, and the wires are relatively thinner. One end is connected to a high voltage load or transmission line, responsible for outputting the high voltage electrical energy generated by induction, achieving the core function of voltage increase.

The core of 300 kva casting resin dry type step up transformer is made of high magnetic conductivity silicon steel sheets stacked together. It is the core carrier for magnetic field transmission and can efficiently conduct the alternating magnetic field generated by the primary winding to the secondary winding,which reduce magnetic field loss and improving electromagnetic induction efficiency. It is the "bridge" for energy conversion in the transformer.

The details are as follows:

1. The 300 kva casting resin dry type step up transformer adopts a reverse operation correction factor of 0.95, reserves 5% power redundancy, and increases the temperature rise margin by 10%. These measures counteract the fluctuating losses on the high voltage side and ensure a stable output of the rated capacity of 300 kVA.

2. Optimize the winding ampere turn layout and layering repositioning process of the 300 kva casting resin dry type step up transformer, suppress the additional eddy current loss caused by reverse magnetic field distortion, strictly control the magnetic flux density of the core to be ≤ 1.55T, and avoid magnetic saturation and excessive loss increase.

3. The axial constant pressure and radial limiting reinforcement structure is adopted to enhance the impact resistance and seismic stability. The vacuum pouring process and end pressure equalization structure are optimized to eliminate the problems of insulation delamination, cracking, and creep aging.
