To deal with global warming, we start from the "heart"

According to the World Meteorological Organization, 2011-2020 is the warmest since meteorological records ten years. Responding to global climate change and mitigating global warming is one of the most pressing challenges in the world's environmental issues. Adhering to the concept of a community with a shared future for mankind, China adheres to the path of low-carbon development, maintains the process of global climate governance, fulfills the responsibility of a major country, proposes the strategic goals of carbon peaking and carbon neutrality, and comprehensively promotes green and low-carbon development.

According to statistics, the country is currently running online There are about 17 million transformers in China, with a total capacity of about 11 billion kVA. Transformer losses account for 40% of transmission power losses. Therefore, reducing transformer energy consumption plays an important role in realizing low-carbon electricity transformation.

Low-carbon operation,"

Haihong's three-dimensional wound core technology has outstanding "double energy-saving" effects: material saving in production - the material utilization rate is close to 100%. Under the scheme of circular coils with the same performance, compared with the traditional transformer structure, the consumption of core materials is reduced by about 25%. , the amount of wire material is reduced by 8%; energy saving in operation - under the same cost comparison, the no-load loss of the three-dimensional wound core is 30% lower than that of the laminated core transformer, the load loss is reduced by 5%, and the no-load current is reduced by 70%.

Three-dimensional wound core technology is widely used in power grids, government projects, photovoltaics, wind power, nuclear power, waste incineration power generation, charging piles and other new energy fields , Data centers, rail transit, port terminals, high-rise buildings, electronics, medical care, education, steel, petrochemical and other fields. So far, more than 180,000 transformers using three-dimensional wound core technology have been in operation on the grid, saving an average of 17.75 billion kW·h of electricity per year, saving 5.367 million tons of standard coal, and reducing 10.36 million tons of carbon dioxide emissions. According to the research of the State Forestry Administration, a tree can absorb and store 4-18 kilograms of carbon dioxide per year. Taking the median value of 11 kilograms, the operation of 180,000 three-dimensional wound core transformers for one year is equivalent to planting about 940 million trees.

Specific different fields, each use one The emission reduction of the three-dimensional wound core transformer is as follows:

    110kV substation——An average annual electricity saving of 85,000 kW·h, Save 25.9 tons of standard coal and reduce 50 tons of carbon dioxide emissions.

The three-dimensional wound core has excellent energy-saving characteristics, and every minute of operation contributes to the response to global climate warming and contributes to "Haihong Power".

New energy, "heart" Power

The new energy power system is the national "fourteenth The key construction projects in the "Five" plan can effectively reduce carbon dioxide emissions, but they have higher requirements for energy saving, stability, and intelligence of power supply equipment. The characteristics of "double energy saving" and high safety and reliability of the three-dimensional wound core technology meet its construction needs.

The photovoltaic smart dual Taking the double-storey public transformer box-type substation as an example, the open three-dimensional wound core dry-type transformer built in the product is safe and reliable in operation. Photovoltaic intelligent double-layer double-male transformer box-type substation adopts two 800kVA high-efficiency and energy-saving open-type three-dimensional wound core dry-type transformers. 9.3 tons of standard coal, reducing carbon dioxide emissions by about 17.9 tons. In addition, the product is also equipped with a photovoltaic power generation system, with an installed capacity of 1350Wp and an annual power generation of 1106kW·h. The photovoltaic power generation of the product can be directly integrated into the power grid, and it is a photovoltaic power generation system to achieve "secondary" zero-carbon operation.
