Since energy saving and environmental protection have become popular words over recent years, we also need to take into account the energy saving effect of transformers when we use transformers, so dry type transformers have become more and more popular. Are you saying that for a reason? Due to the fact that dry-type transformers’ energy-saving effect and efficiency are constantly improving, it can be said that the energy-saving effect and energy-saving advantages of dry-type transformers are greatly improved. Furthermore, due to the large amount of energy generated, the economic development is more powerful.
Dry-type transformers reduce no-load losses by about 80% and no-load current by about 85% compared to traditional silicon steel dry-type transformers. The dry-type distribution transformer is especially suitable for rural grids and developing areas where distribution transformers are not utilized to their full potential. The amount of power consumed by rural power grids in my country is influenced significantly by seasonality. In the case of distribution dry-type transformers with light loads or no loads, the load variation gap accounts for 70% to 80% of the total operational time. This gap increases in arid regions irrigated by motor-driven wells, where the load variation gap for dry-type transformers is even greater. Dry-type transformers are widely used in the rural grids, which will certainly result in a huge reduction in energy consumption in the long run.
According to the survey results of the dry-type transformer factory, there are currently over 10,000 high-power distribution dry-type transformers that are below the S7 type used in rural power grids, with a capacity between 30 and 200 kVA, and an annual sales volume of about 800 million kilowatts. It would cost about 36 million yuan more to invest in equipment if only dry-type transformers were used, with the average reduction of 2% to 4% in dry-type transformer losses, the annual power loss can be reduced by 24-30 million kWh, resulting in more than 10 million yuan in benefits for the enterprise, and the difference in investment can be recovered in about 4 years.
Dry-type transformers have been used to transform rural power grids, increasing the speed of rural power grids. Dry-type transformers are continuously being used to transform power grids. The results and improvements are continuously improving the rural economy.
