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”
Automatic cutting of silicon steel sheet Hengfengyou Electric，power transformer and distribution transformer Production process display.High efficiency, high precision.
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 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. The pressure of epidemic prevention and control is huge. When will this world disaster end?”
Based on the assumption that “vaccines and treatments will come out in 2021, the global economy will start to recover in the second half of the year, and electricity demand and industrial output will increase”, the IEA believes that energy demand will rebound sharply. In terms of oil demand, IEA believes that the excess supplyContinue reading “World energy trends in 2021”
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 “What is the “six degree principle” of power distribution transformer”
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?”
On June 28, 2021, the first batch of units of Baihetan Hydropower Station on Jinsha River in China, which is the largest hydropower station under construction, the largest single unit capacity in the world and the second largest installed capacity in the world, will be officially put into operation. Located in Liangshan Prefecture of SichuanContinue reading “Baihetan Hydropower Station has been officially put into operation for power generation, adding a super project to achieve the goal of carbon neutralization and carbon peak by 2030!”
China’s sustained high-speed economic development and rapid growth of power demand (China’s electricity consumption is growing at an average rate of 9%), led to the development of China’s transformer manufacturing industry.
1、 U.S. grid operators:The U.S. power grid is mainly composed of three scattered and interconnected parts: the eastern power grid, the western power grid and the Texas power grid. Most of the lines and substations are private companies, plus more than 500 independent power grid operating companies, which also lowers the threshold for domestic smallContinue reading “Analysis and forecast of American electricity market in 2021”
