Transformer operation and maintenance and fault handling schemes

The operation and maintenance and fault handling scheme of the transformer The operation and maintenance and fault handling scheme of the transformer, the power transformer plays a very important role in the power plant, however, due to its structure, process and operation and maintenance, the power transformer has a very important role in the power plant, however, due to its structure, process and operation and maintenance and other reasons, the transformer failure occurs frequently in the power plant, which greatly affects the normal production of the power plant. Therefore, it is important to strengthen the regular maintenance of transformers and take practical and effective measures to prevent the occurrence of transformer failures to ensure the safe and stable operation of transformers

Policy support for the development of energy-saving transformers and analysis of market dynamics

Analysis of energy-saving transformer development policy support and market dynamics Although energy-saving transformers have very outstanding advantages in technical performance, China is currently vigorously promoting the popularization stage, but in terms of market acceptance, it is not optimistic.　　Power transformer is the key electrical equipment for power transmission, transformer loss accounts for 30% ~ 40% of the power grid loss, and all transformers in China account for more than 3% of the country's power generation. Therefore, the state has been focusing on energy conservation and consumption reduction of transformers, and vigorously promoting energy conservation and emission reduction.　　As early as August 21, 2012, the State Council issued the "Twelfth Five-Year Plan for Energy Conservation and Emission Reduction".

Energy efficiency trends in the transformer industry

Energy efficiency trend in the transformer industry transformer industry to accelerate the integration of high energy-consuming products will withdraw from the stage On June 9 last year, the Standardization Administration of the People's Republic of China issued the GB20052-2013 "Three-phase Distribution Transformer Energy Efficiency Limits and Energy Efficiency Grades" announcement, and implemented on October 1, 2013, at the same time, the application for energy-saving certification certificate will also be closed before December 31, 2013.　　According to the announcement, the three-phase distribution transformer standard has increased the content of energy efficiency grades compared with the old standard, increased the energy efficiency limit value of transformers, and deleted the provisions on "target energy efficiency limit value". Since October, three

The amount of electricity connected to the grid of renewable energy in the country has increased year by year

By the end of 2013, the grid-connected installed capacity of wind power and photovoltaic power generation of the State Grid has reached 70.37 million kilowatts and 15.46 million kilowatts respectively, a year-on-year increase of 24% and 360%, and the State Grid has become the world's largest wind power grid, the fastest growing photovoltaic power grid.　　In recent years, China's wind power, hydropower and other renewable energy grid-connected electricity has increased year by year, especially in 2013, distributed photovoltaic power generation projects have sprung up across the country. According to data from the Jiangsu Provincial Energy Bureau, by the end of 2013, the cumulative installed capacity of distributed photovoltaics in Jiangsu Province reached 650,000 kilowatts, ranking first in the country.

Pressure transmitters and electronic transformers need to be innovative

In the electronic transformer industry in the middle position, only by taking the road of technological innovation can we break free from the dilemma of being gassed at both ends. The electronic transformer in the power supply, like all products as a commodity, must complete the detailed function under the premise of detailed use, and pursue the best function-to-price ratio in any technological innovation.　　Over the years, the price of oriented and non-oriented cold-rolled silicon steel has risen, and the coiled annular core, compared with the R-type, CD-type and EI-type core, can save more than 20% of the cost of core materials because of the less material consumption, and expand the scope of use in electronic transformers. The coiled annular core can be fully oriented cold rolled

Analysis of the development direction of the power transformer industry this year

Power transformer is the key electrical equipment for power transmission, transformer loss accounts for 30% ~ 40% of the power grid loss, and China's transformer itself loss accounts for more than 3% of the national power generation. China's "Twelfth Five-Year Plan for Energy Conservation and Emission Reduction" requires the "Twelfth Five-Year Plan" period to reduce the loss of power transformers, including no-load losses reduced by 10% ~ 13%, load losses reduced by 17% ~ 19%, and some high-energy consumption distribution transformers currently operating on the network have not met the development trend of the industry. The state has been promoting the energy saving and consumption reduction of transformers. At the beginning of the new year, Tian Wei of the National Power Transmission and Distribution Technology Cooperation Network Substation Branch expressed his views

The transformer manufacturing industry is developing towards environmental protection, miniaturization and high reliability

The transformer industry is closely related to the national grid construction policy. At present, the Chinese government and industry authorities attach great importance to the contradiction of imbalance in power grid and power supply investment, and are committed to solving the problem of lagging power grid construction and weak grid structure, so as to adapt to the rapid growth of power demand and realize the comprehensive and coordinated development of power grid and economy and society.　　During the "Eleventh Five-Year Plan" period, the state increased investment in the power grid, with the investment of the State Grid Corporation of China being 1,215 billion yuan and the Southern Power Grid Corporation of 234.1 billion yuan; During the "Twelfth Five-Year Plan" period, the State Grid has invested a total of 1.8 trillion yuan in the power grid. During the "13th Five-Year Plan" period, the investment in the construction of the State Grid will reach about 2 trillion yuan. country
