The Development Prospects of Transformers
1. Intermediate frequency transformers have a large output and low price, and are mainly exported, which drives their rapid development. At present, the industry average price of intermediate frequency transformers for enterprises in China’s electronic system is 0.626 yuan/unit, but the average factory price for most enterprises is between 0.20 and 0.30 yuan/unit, with the highest being around 1 yuan/unit.
2. The market demand for power transformers is strong. Power transformers are labor-intensive products that are mainly customized by users. In recent years, there has been strong demand in domestic and international markets, making them a rapidly developing popular product. According to the “2013-2017 Market Demand Forecast and Investment Strategy Planning Analysis Report of China’s Power Transformer Industry” by Forward looking Network, India is expected to grow by 25%. Communication, computers, and consumer electronics products are its three main markets, with the growth of communication demand playing a significant driving role. Currently, the global annual demand for power transformers has exceeded 10 billion US dollars and is developing towards surface installation, high-power, and high-voltage.
If amorphous alloy transformers can completely replace the new S9 series distribution transformers, such as 10kV level distribution transformers with an annual demand of 50 million kVA, then they can save 10 billion kW of electricity in one year? Above h. At the same time, it can also bring good environmental benefits of building fewer power plants, reducing greenhouse gas emissions into the atmosphere, greatly reducing direct pollution to the environment, making it a new generation of truly green and environmentally friendly products. In summary, if the country can widely promote the use of three-phase amorphous iron core distribution transformers in the development and renovation of urban and rural power grid systems, it will ultimately achieve energy-saving and environmental benefits.
According to a research report released by MarketsandMarkets, the world’s second-largest market research institution, the global power transformer market is expected to generate revenue of $20.71 billion (approximately RMB 132.04 billion) in 2015. With the continuous growth of electricity demand and the continuous improvement of transmission and distribution infrastructure, this figure is expected to increase to $29.91 billion (approximately RMB 190.7 billion) by 2020, with a compound annual growth rate of 7.6% during this period.
The report points out that the continuous growth of global electricity demand will lead governments, both developed and developing countries, to increase investment in power generation facilities and transmission and distribution infrastructure to meet the needs of economic and social development. It is expected that global electricity demand will continue to grow at an annual growth rate of 2.4% from 2009 to 2035.
Power supply method of transformer
The 10KV high-voltage power grid adopts a three-phase three wire neutral ungrounded system operation mode.
The user transformer power supply mostly adopts the neutral point direct grounding system operation mode of Yyn0 connection, which can achieve three-phase four wire or five wire power supply, such as TN-S system.
