Description
Technical field
The present invention relates to distribution automation controlling of sampling field, specifically disclose a kind of one or two fusion three-phase electricity of controller switching equipment
Pressure transformer.
Background technology
China intelligent grid builds huge investment, and it is former dynamic to be that Power Equipment Manufacturing Enterprise provides powerful technological transformation
Power.National grid proposes 2009～the year two thousand twenty and divides three phases to realize intelligent grid perspective long-term plan：First stage (2009～
2010) 550,000,000,000 yuan of projected investment, second stage (2011～2015) projected investment 2 trillion yuan, the phase III (2016
Year～the year two thousand twenty) projected investment 1.7 trillion yuan.To the year two thousand twenty national grid, in terms of intelligent grid construction, gross investment exceedes 4,000,000,000,000
Unit.The strong intelligent grid of China's construction unification will construct strong grid structure, need substantial amounts of transformator, transformer etc.
It is estimated that this respect equipment accounts for electrical network gross investment 40%, this is undoubtedly the Gospel of Power Equipment Manufacturing Enterprise to equipment.
With the enforcement of State Grid Corporation of China's strong intelligent grid plan, transformer station will develop to intelligent substation, once
Equipment will upgrade to intelligent power equipment, and secondary device then becomes intelligent control unit, and this is a revolutionary change.Country
Electrical network has issued the overall technology planning requirement of intelligent substation for products such as transformator, transformers it should add representative
Intelligentized autodiagnosis, defencive function.
