High-energy transformers are the main generators of small and medium-sized factories in China. The equipment sold in the 1980s is quite large. The main reason is that the production capacity in the 1980s is relatively backward, and it is just the importance of the rapid development of society. In the era, the high energy consumption of its equipment has always become a major event for users. Take the S7 type transformer, this is the product of the 1980s. The technology is lagging behind the power loss. The country has already listed this product in the list of outdated equipment.
We consulted Li Bo, who worked in the injection molding factory a few decades ago, and said, "We only need one boot every day, the factory manager will shout or supervise in the workshop to prevent us from breaking the gap and wasting current, even if it is like this. The monthly electricity bill is still high and scary." But after hearing about the energy-saving transformation of the injection molding machine, the expenses have been reduced a lot.
With the advancement of high technology and the call for energy conservation and environmental protection, the country has begun to pay attention to it. Some subsidies for energy-saving renovations have been subsidized. The amount of subsidies is around 30%. Some families with relatively good conditions are better than the average. The energy-saving renovation of existing buildings began. The scope of the renovation is generally the external walls, doors and windows. The main purpose is to prevent air leakage and waste. Another big energy-saving retrofit is our factory. The annual electricity consumption of the factory is very large, which causes the cost of the enterprise to be greatly improved. Energy-saving renovation is imperative for them.
According to statistics, according to the annual electricity cost of 400 kVA high-energy transformers, the annual electricity bill will be reduced to 38,000 yuan, and the national energy-saving renovation subsidy will be reduced by 50%. Compared with 70% of the cost before the renovation, the cost of energy-saving renovation will be recovered within 3 years.
For example, in 2012, the Cixi Power Supply Bureau completed a total of 691 S7-type transformers with energy-saving transformation, with a total capacity of 11.2 MVA. It is expected to save 2.24 million kWh per year, equivalent to saving 807 tons of standard coal and reducing CO2 emissions. The emission of tons of sulfur dioxide and 7.02 tons of sulfur dioxide bring huge economic and social benefits. Energy-saving transformation of injection molding machine: http://
