Happy Lantern Festival！

To 2022 COVID-19
All changes change, but change remains the same
If you want to perish, you must be crazy first
Family business, relatives, customers
Master the same, and ultimately benefit
I have to admire the wisdom of Chinese ancestors. Through the observation of celestial phenomena, I summed up the natural laws of the operation of nature, which is simple and effective. Since the global dissemination of the new crown in 2019, countless facts have confirmed the correctness of the earth mother Sutra, the back pushing map and the three yuan and nine movements theory of the book of changes. For a person who deeply loves the culture of Sinology, he deeply feels the greatness of Chinese Sinology and the wisdom of Chinese ancestors!
The new crown broke out nearly three years ago. With the wisdom of our ancestors, this is a century plague. But the bigger plague is only three years. Before the beginning of spring, COVID-19 must be the last craziness.

Recently, the Ministry of energy of Uzbekistan announced the launch of scaling solar 3 project. The project is in line with the development of Uzbekistan's power supply and implementation of large-scale renewable energy strategy in 2020-2030, indicating that Uzbekistan is on the road of sustainable, clean and diversified energy production.
The project is planned to start in February 2021 and generate up to 5 gigawatts of cost-effective and clean solar energy over the next 10 years. According to HENGFENGYOU electrical engineer's estimation, the project will generate 2 billion US dollars of transformer and other distribution equipment demand.

The future development trend of power transformer technology -- high frequency power transformer
High frequency power transformer, also known as power electronic transformer, is a new intelligent transmission and transformation equipment, which can realize the flexible transmission of power, improve the stability of power system operation and power supply reliability. Compared with traditional power frequency transformer (also known as low frequency transformer), the voltage waveform of high frequency power transformer has the characteristics of short rising time and frequency up to 10 kHz (power frequency is 50/60hz). In order to ensure the miniaturization and high efficiency of equipment, dry structure, namely gas + solid insulation structure, is generally adopted.

The high frequency transformer has the following advantages:
1. the same capacity is smaller, the equipment materials are greatly reduced, and the production cost is reduced by 30-50%
2. high frequency rate means low loss and low noise, which can reduce 20-70% loss and noise.
3. the ultimate manufacturing capacity of transformer is improved, and it is convenient for transportation and installation.
The high frequency transformer has the following disadvantages:
1. the reduction to sine wave has distortion, complex circuit and high failure rate
2. high frequency transformer can not replace power frequency transformer completely, especially high power and power transformer
3. increase the short circuit current of power system, and increase the single-phase short-circuit current greatly, sometimes even exceed the three-phase short circuit current
4. some difficulties in voltage regulation and complex relay protection are caused.

Generally speaking, whether electronic or power transformer, high frequency transformer is the future development trend, because the advantages of high-frequency transformer are huge, replacing traditional power frequency power transformer is only a matter of time. Therefore, all countries in the world attach great importance to the R & D and manufacturing of high-frequency power transformers. For example, ABB, GE, China XD Electric and TBEA, etc., which are well-known in the world, have already laid out the development of high-frequency transformers. QingDao HENGFENGYOU ELECTRIC has also started the research and manufacture of high-frequency transformers since 2012. Recently, the introduction of high frequency power transformer technology of Japanese power enterprises has made the high-frequency power transformer of its own With the technology becoming more and more mature, it is believed that in the near future, the power transformer market will usher in great changes.

Successful acceptance of the world's largest 110kV dry type transformer
Warm congratulations on the successful acceptance of China's on load voltage regulating Epoxy Resin Dry-Type Power Transformer (hereinafter referred to as "110kV dry-type transformer"). At present, the capacity has reached 63000KVA, which is the largest, most environmentally friendly and safe 110kV dry-type transformer in the world. Martin, chief analyst of HENGFENGYOU ELECTRIC, believes that 110kV dry-type transformer has always been a world-class problem according to the data analysis of the international electrical industry. It represents the future development direction of substation
transformer in the world and is a product with great promotion prospects.

Vietnam's Ministry of industry and trade recently released a draft of the national power development plan for the period 2021-2030 and for 2045, according to Vietnam's investment daily on February 24. According to the plan, the investment demand of Vietnam's power development in 2021-2030 is 128.3 billion US dollars. Among them, the investment in power generation is 95.4 billion US dollars, and the investment in power grid development is about 32.9 billion US dollars.
The investment in power grid transmission and distribution in the United States, the United Kingdom, Japan and other countries is about 1.2 times that of power supply, and the investment in distribution network is more than 1 times that of transmission network (calculated by 0.5 times according to Vietnam's development level). Hengfengyou Electric believes that Vietnam's distribution equipment market will be at least $16 billion in the next decade.

The 20th China Electrical Culture Festival will be solemnly opened on January 31, 2020 (the seventh day of the first month of the lunar calendar) in Liushi, the "capital of electrical appliances in China". HENGFENGSHUAI ELECTRIC will participate in the exhibition and look forward to cooperating with customers at home and abroad.

Power generation ranking of countries in the world

Does 2020 really mean the beginning of the end of coal?
In the first half of 2020, the world has lost 2.9GW of coal power generation capacity (GEM report said). With the global spread of covid-19, power generation enterprises must adopt the most flexible power generation mode to adapt to the future energy supply, and reducing pollution is an additional incentive. Therefore, "renewable energy has brought a glimmer of hope for the power industry". It can be predicted that the new coronavirus will bring a glimmer of hope for the power industry After that, it will inevitably lead to a wave of global new energy construction climax.

China's transformer industry will exceed 500 billion in 2021
At present, China's transformer enterprises can be divided into three camps:
The first camp: it is composed of ABB, Areva, Siemens and other multinational corporations, occupying 20% - 30% of the market share;
The second camp: large domestic enterprises such as BaoBian Transformer Co., Ltd., Special Transformer Co., Ltd. and Xi'an transformer substation Co., Ltd. occupy 30% - 40% market share by upgrading the technical level and level of products;
The third camp: it is composed of Qingdao hengfengyou Electrical Engineering Co., Ltd. and other private enterprises. Due to flexible operation mechanism, excellent product quality and moderate price, it has also formed a certain market share.
In 2019, the export amount of China's transformer was 333.7 billion US dollars, with a year-on-year increase of 3.3%

47000 novel coronavirus pneumonia confirmed cases and 600 deaths were reported in the United States in October 4th. The sufferings faced by these patients are heartbreaking.
