Amorphous transformer favored, future or mainstream products

    The Amorphous metal transformer is an energy efficient transformer developed by the 1970s. The first country in the world to develop the Amorphous metal transformer was the United States, general Electric (GE) was then in charge of the research and development of the Amorphous metal transformer. By the end of the 1980s, commercial production had been completed. Using a new type of soft magnetic material -- A non-crystalline alloy -- the Amorphous metal transformer is more versatile than any other type of silicon steel transformer. Following China's policy of "Energy Conservation and consumption reduction" , the state encourages the development of energy-saving, low-noise, intelligent distribution transformer commodities. The future energy-saving, material-saving, environmental protection, low-noise Amorphous transformer with its significant energy-saving advantages in the future distribution transformer category occupies an extremely important position. A new round of Rural Power Grid Renovation has sounded the clarion call, and the State Council General Office recently forwarded the National Development and Reform Commission's "advice on implementing a new round of rural power grid renovation and upgrading projects during the 13th five-year plan period" , proposed to implement a new round of Rural Power Grid Upgrading Project. According to the report, by 2020, rural areas throughout the country will have completed a complete and stable coverage of power supply services, and the ability and level of power supply services will have significantly improved. Rural Power Grid power supply can be considered up to 99.8 percent, and the average distribution and distribution capacity of households will be no less than 2,000 volt-an. An important link in the transformation of Rural Power Grid is the question of distribution transformer transformation, which is related to the long-term economic benefit of rural power grid transformation. The loss of transformer in operation is a question that should be fully considered in the transformation of Rural Power Grid. Amorphous transformer has significant advantages in the new round of rural power grid transformation. The strong seasonal load is the main feature of China's Rural Power Grid. Generally speaking, the load density of China's rural power grid is low and LAX. Due to the fact that the rural population in China usually lives in a relatively lax electricity consumption load, and the strong seasonal nature of rural output, rural electricity consumption has seasonal characteristics, especially in times of drought, this often results in overloading the grid and resulting in low grid voltage. In addition, rural power equipment throughout the year only a small period of time to use, distribution lines are often in the light load or outage status, which makes the rural power grid integrated use less time. Amorphous transformer is made of amorphous material instead of silicon steel sheet. Its outstanding features are low no-load loss, no-load current small, compared with the same type of S9 series transformer no-load loss reduced by 70%-80% , no-load current reduced by 40%-60% , load loss reduced by 20%-30% , so it has a great energy-saving effect. The light load or no load operation time of distribution transformer accounts for 70%-80% of the total operation time in China's rural power grid. especially in dry areas irrigated by machine wells, the load change gap is larger, and it is especially suitable for the use of Amorphous metal transformer, the potential for unlimited energy savings can be realized. The environmental protection and economic benefits of the Amorphous transformer are remarkable. According to the professional estimation, if the amorphous transformer can completely replace the new S9 series distribution transformer, such as the annual demand of the 10kV grade distribution transformer is calculated at 5 million KVA, it can save more than 10 billion kw hours of electricity a year, and the economic and environmental benefits are very considerable. An experiment with Amorphous transformers has shown that they can reduce line losses by 2-4 per cent a year compared with S11 transformers of the same capacity and close to the load, thus reducing huge power losses. The reduction of electricity lost together is an increase in economic efficiency, although the quoted prices of amorphous transformers are usually 25% higher than those of the same capacity of the S11 transformer (for example, the 100kVA transformer is 17,500 yuan for the S11 transformer and 22,200 yuan for the same capacity of the amorphous transformer, 45,000 yuan more than that of the S11 transformer) , however, it can reduce the cost of electricity, in the long run is of infinite economic benefits. Taking Jilin as an example, there are more than 12000 high-consumption distribution transformers of Model S7, with a capacity of 30-200kVA and an annual sales capacity of about 800 million kw hours. It can be seen that the use of Amorphous metal transformer is the first choice in the transformation of rural power grid, which can be invented with higher economic benefits. It is concluded that the amorphous transformer can save energy and achieve remarkable economic benefits. Its use in the distribution network will be useful to reduce the loss of the distribution network, in line with the national industrial policy and the requirements of the power network for Energy Conservation and consumption reduction, it is expected to become the leading commodity in the transformer market in the future.
