By analyzing the influence trend of these influencing factors on the withstand voltage strength of transformer oil, it shows that the higher the voltage level of transformer, the stricter the control requirements for water content, gas conte...

Oil immersed transformer is called insulating oil. Its function is to prevent breakdown. If the high-voltage end of the transformer is not insulated, corona or breakdown accidents will occur, causing losses to staff and equipment. Transform...

Common fault causes and solutions of transformer: it is mainly due to poor welding quality, false welding, desoldering, pinhole, sand hole and other defects in the weld, and the power transformer is covered with solder and paint when leaving...

Oil immersed transformer explosion accidents occur frequently. Because the explosion process of oil immersed transformer is a relatively slow development process, once the explosion occurs, there will be casualties and huge economic losses, ...

Different transformers can directly see the iron core and coil, while oil-type transformers can only see the outer shell of the transformer; most dry-type transformers use silicone rubber bushings, while oil-type transformers mostly use cera...

When the winding temperature of transformer is in the range of 80 ~ 130 ℃, the insulation aging speed will be doubled for every 6 ℃ rise in temperature, that is, the insulation life will be reduced by 1 / 2 for every 6 ℃ rise in temper...

Hengfengyou Electric has observed that in recent years, the global output of transformers with aluminum coils is huge, and the phenomenon of some transformers with aluminum coils passing off as copper is prominent. Many people define transfo...

Focusing on global carbon neutralization and carbon peaking, the mandatory national standard GB 20052-2020 "energy efficiency limits and energy efficiency grades of Power Transformers" formulated by China's State Administration of market sup...
