Analyzing the development status of China's transformer industry, we learned that with the continuous development of the transformer industry, more and more companies have entered the transformer industry, and many companies have stood out. For example, Mingyuan Transformer was founded in the early 21st century by a joint venture company. , reactors, filters and other R & D and manufacturers, after nearly ten years of development, has become one of the few advanced technology leaders and pioneers in the industry.

Transformer In electrical equipment and wireless circuits, transformers are often used for voltage rise and fall, impedance matching, safety isolation, etc. In a generator, whether the coil moves through the magnetic field or the magnetic field moves through the fixed coil, an electric potential can be induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux that intersects the coil is different. Change, this is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current and impedance. In its most basic form, a transformer consists of two sets of coils of wire wound inductively coupled to each other.

The competition in China's transformer industry is fierce, foreign multinational companies have seized a large market share, and the number of domestic transformer manufacturers is also growing rapidly. The competition in the low-end transformer market is fierce. There are more than 20 enterprises with the production capacity of 220KV transformers, and more than 100 enterprises with the production capacity of 110KV transformer products. However, enterprises producing transformers above 500KV have built high barriers to entry through technology and production capacity, and the market pattern has tended to stabilize.

In recent years, my country's electricity demand has grown rapidly, and the rapid construction and investment of power grids has driven the market demand for power transmission and transformation equipment. The huge investment in power construction has brought opportunities and challenges to the transformer industry, which has prompted the rapid development of the transformer industry. It is expected that during the 'Twelfth Five-Year Plan' period, the growth rate of my country's transformer market will remain around 10%.

According to the disclosed investment targets of the State Grid and China Southern Power Grid, the two major power grid companies will invest more than 500 billion yuan in total during the 12th Five-Year Plan period, of which the State Grid is expected to invest nearly 400 billion yuan and China Southern Power Grid is expected to invest 111.6 billion yuan. .

In recent years, the global market demand for power transmission and distribution equipment has generally shown an upward trend. In the recent period, the construction of projects such as west-to-east power transmission, north-south mutual supply, and cross-regional networking has driven the rapid development of my country's power transmission and distribution equipment industry. Judging from the current market development, the transformer manufacturing industry will usher in a sustained and stable development period.

The upgrading and transformation of traditional transformers will generate a large market share, and the elimination of outdated products can promote the effective development of bidding work, and huge economic benefits will appear. The research and development, manufacturing, sales, use and maintenance of energy-saving and intelligent transformers will become mainstream, and new products will inevitably bring new development opportunities to the industry.

Transformers are the key electrical equipment for power transmission. Due to the large number of them, the power consumption of the transformer itself is also considerable. Relevant data show that at present, the electric energy consumed by all transformers in my country accounts for 3% to 10% of the national power generation. In the loss of the distribution network, the loss of the transformer accounts for 40% to 60%, and the energy saving potential is huge.
