Operation part of power transformer accessories

Power transformer accessories are important equipment for power grid distribution, mainly including transmission transformers operating in the main power grid and distribution transformers operating at the terminal. At present, transformer products are classified by voltage into high-end transformers, 220-500 kV transformers, 110-200 kV transformers, and transformers below 110 kV.

It can be said that the development of transformer bushings is closely related to power construction, and China is currently at the peak of power construction. From the perspective of new installed capacity in China, it can be found that 2001 was a low period for new installed capacity in electricity. In 2003, it entered a recovery period, and in 2004, power construction showed a surge. The installed capacity of power stations approved by the state was 60 million kilowatts, but the actual construction started reached 150 million kilowatts, which is 2.5 times the national plan. To this end, the State Council issued Document No. 32 in December 2004, namely the Emergency Notice of the State Council on the Approval and Transmission of the Opinions of the Development and Reform Commission on Resolutely Stopping the Disorderly Construction of Power Station Projects, which carried out macroeconomic regulation on the construction of transformer conductive poles.
