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...

Transformers are required in most areas where electricity is consumed. This is not practical. If the output detection is 380V, the high voltage is generally 10kV, and some auxiliary high voltages are 6kV, the transformer is selected accordin...

Abnormal sound of distribution transformer, overheating of distribution transformer, significant change of insulating oil color of distribution transformer, oil injection of conservator or explosion-proof pipe, relay protection action, three...

Traditionally, the power system is divided into four systems: power supply, transmission, distribution and power consumption. By power supply and distribution, we mainly refer to power supply system and distribution system....

Silicon steel sheet is a kind of silicon iron soft magnetic alloy with very low carbon content. Generally, the silicon content is 0.5 ~ 4.5%. Adding silicon can improve the resistivity and maximum permeability of iron, and reduce coercivity...
