30kV Oil Immersed Power Transformer

Performance Characteristics

1.Low Loss

The iron core is cold rolled silicon steel with high quality and high magnetic permeability, and the iron core binding adopts the overall pressure and PET belt binding process, which effectively reduces the no-load loss and no-load current of the transformer.

2.Low Noise

The noise of the oil-immersed self-cooling transformer is mainly caused by the electromagnetic noise of the iron core. In order to reduce the noise, our company has taken the following measures:

A.low flux density design;

B.High-quality high-permeability silicon steel sheet;

C.The Swiss automatic laminating machine is used to control the laminating accuracy;

D.reliable clamping and supporting measures;

Special shock absorption measures.

3.No Leakage

The oil tank and oil storage tank have undergone positive and negative pressure leakage test to ensure that there will be no oil leakage during normal operation of the product. The assembly is installed with a flange groove structure and is formed at one time. All seals are made of high-quality one-time molded acrylic rubber parts to prevent oil leakage.

4.Energy saving and environmental protection

S series 35KV power transformers meet the 2020 new national standard energy efficiency standards; S18 meets the 2020 version of the new national standard level 3 energy efficiency; S20 meets the 2020 version of the new national standard level 2 energy efficiency; S22 meets the 2020 version of the new national standard level 1 energy efficiency.

5. Strong ability to resist short circuit

In order to ensure that the transformer can withstand the impact of short-circuit current, and under the condition that the rated voltage is applied on the primary side and the secondary side is completely short-circuited, under the action of short-circuit current, it will not cause thermal and mechanical damage.

A.the transformer coil for a reasonable turn balance calculation, using semi-hard copper wire;

B.The strength and stiffness of the iron core clamping parts are calculated to meet the safety requirements of short-circuit mechanical force;

C.the winding pad is densified, and high-density hard cardboard is selected;

D.The winding adopts a reasonable structure with uniform distribution of compacting blocks, and the assembly height is uniform and the force is uniform, which ensures the ability to resist short circuit;

Take some special measures to prevent the coil from being deformed by force.
