1. Winding copper loss boring method: through the transformer winding, the power generation itself generates heat, heats the winding insulation, has small operation volume, fast temperature rise and saves time. The defect is that the workloa...

Check regularly to ensure that the transformer's explosion-proof membrane and safety relief valve are intact and prevent direct contact with air, which will increase the moisture in the transformer oil and deteriorate the insulation performa...

The automatic control of forced oil circulating air cooling oil immersed transformer is designed according to the following principles. When the load of the container drops to the specified value, the auxiliary cooler will cut off automatica...

The voltage of French medium voltage power grid is 20kV. Low voltage: 220V / 50Hz. Hengfengyou electric complies with ISO, Kema NF and en transformer standards and has provided customized services for oil immersed transformer cores and trans...

According to the electrical engineer of Qingdao hengfengyou, power products refer to power generation, transmission, transformation, distribution, power consumption and equipment. It is mainly divided into primary equipment, secondary equipm...

What is the difference between box type substation and box type transformer? Transformer is a device that transforms AC voltage, current and impedance. When AC current is connected in the primary coil, AC magnetic flux will be generated in t...

When the transformer supplies power to the load, the voltage at the load end of the transformer will inevitably drop. Compare the falling voltage value with the rated voltage value, and take the percentage, that is, the voltage change rate（...

The first function of oil immersed transformer oil is insulation. The insulation strength of transformer oil is much higher than that of air. The insulation material immersed in oil can not only improve the insulation strength, but also be f...
