Farady 500kva power transformer

farady 500kva power transformer has a notable feature large capacity, and the power to follow the principles of building a modest advance in economic development, in the past over-capacity operation of the transformer and rare. However, in recent years with the rapid development of national economy, the power supply and the load tends to be centralized, large-scale increase 500kV farady oil immersed power transformer capacity operation. Because of the large oil immersed power transformers, high cost, large capacity, wide supply range and impact is large, there is a big risk of capacity. farady transformer capacity convenient ability to run traditional search load table method to obtain fast, but for different parameters heat high pressure, high-capacity viewing results immersed power transformers for inaccurate, is not conducive to running the risk of capacity in advance of such transformers of an accurate assessment. Operating personnel by monitoring transformer hot spot temperature to determine their ability to run, albeit capacity, but are afterwards control, does not comply with the principle of pre-control risk. It is necessary according to the temperature rise test data on the capacity to run a large capacity 500kV oil immersed power transformers were calculated and analyzed, so as to achieve effective control of the power grid risks and safeguard supply security purposes.
