Six degree principle of power transformer

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 temperature. This is the “six degree principle” orContinue reading “Six degree principle of power transformer”

Ranking of global power generation in 2019 and global per capita power consumption in 2020

In 2019, the power generation of all countries and regions in the world will exceed 27 trillion kWh (27004.7twh) for the first time, with a year-on-year growth of 1.3%. In 2020, global coal-fired power generation will drop by 4% year-on-year in 2020, the largest decline in history. In 2019, China’s power generation continues to rankContinue reading “Ranking of global power generation in 2019 and global per capita power consumption in 2020”

Recently, the delta variant virus is rampant all over the world, and the epidemic situation in many Asian countries is intensifying. The pressure of epidemic prevention and control is huge. When will this world disaster end?

Recently, the Asian region: Delta, a virus in Indonesia, Japan, Vietnam and Singapore, has been raging. The Asian Multi Country epidemic has intensified. The epidemic prevention and control pressure is enormous. In the past, we found that it took 15 minutes for people to infect COVID-19 from another person less than one meter away. Now,Continue reading “Recently, the delta variant virus is rampant all over the world, and the epidemic situation in many Asian countries is intensifying.

Is aluminum core transformer good or not?

Hengfengyou electric observed that in recent years, the global output of aluminum coil transformer is huge. Many people define the transformer made of aluminum coil (distribution transformer) as “transformer fraud”, and attribute many transformer accidents to “replacing copper with aluminum”! It really obliterates the legitimacy of this product and the contribution it has made atContinue reading “Is aluminum core transformer good or not?”
