矿热炉变压器 的先进技术和装备,使我国矿热炉变压器得到迅速发展。 In the 1980s and 1990s, many domestic transformer factories invested a lot of funds and introduced advanced technology and equipment from foreign mine heat furnace transformers , which enabled China's mine heat furnace transformers to develop rapidly. The number of manufacturing plants has gradually increased from the original seven or eight to dozens, and there are now thousands.

Transformer is an important equipment for power distribution in the power grid. It mainly includes two parts: a transmission transformer running on the main grid and a distribution transformer running on the terminal. Since the Tenth Five-Year Plan period, China's power demand has grown rapidly and power supply has been tight. The high-speed construction of the national power grid and the government's investment in fixed assets drive the market demand for power transmission and transformation equipment, giving companies engaged in power transmission and transformation equipment such as transformers a great room for development. The great development has brought great prosperity. The huge power construction funds have brought opportunities and challenges to the transformer industry, and the industry has achieved great development in history.

Since the early 1990s, foreign companies have noticed that China has such a huge transformer market, as well as preferential tax policies and cheap and skilled employees, have come to China to establish joint ventures, and most of them have obtained controlling rights. They have gained a lot of share in the Chinese market and made a good profit. We believe that with the strong promotion of power construction, the economic operation of the national transformer industry has maintained a good development trend. Transformer market demand mainly comes from two aspects: on the one hand, the rapid growth of installed power generation capacity; on the other hand, the capacity ratio of transformer equipment and power generation equipment is gradually rising.

During the operation of the transformer, if it encounters short circuit, overload, high ambient temperature or insufficient cooling and ventilation, it will cause the transformer to overheat. For the transformer of the mineral heat furnace, its thermal balance performance is poor, and the winding temperature exceeds the insulation withstand temperature and the insulation is destroyed, which is the main reason that the transformer can not work normally. 运行的重要部件,能有效防止变压器温升过高引发事故,还能促进变电站的科学管理,通过降低温度实现变压器的经济运行。 The temperature control system for the transformer of the mine furnace is an important part for maintenance and operation, which can effectively prevent accidents caused by excessive temperature rise of the transformer, and can also promote the scientific management of the substation, and achieve economic operation of the transformer by reducing the temperature. 运行质量。 The reliability of its work and the convenience of operation will directly affect its operating quality. Therefore, it is very important to monitor the operating temperature of the transformer winding and drive the fan to achieve forced air cooling and alarm control.
