At present, to improve energy efficiency, reduce energy consumption has become the direction of industrial development in the process of construction of power grids, transformers play a very important role. The power transformer is a critical electrical equipment, transformers, transmission of electricity consumption accounted for 30% to 40% of the grid loss since.
Effective energy-saving transformer, in the July 1 implementation of the national mandatory standards for the power transformer energy efficiency of limited value and energy efficiency rating \". Mr. Zhao Yuejin of the Chinese Institute of Standardization senior engineer, said: \"The old and new replacement of the transformer, the transformer economic operation of (20) estimates, the cumulative savings of 70 billion kwh of electricity consumption, equivalent to 32 million tons of standard coal, can reduce 69 million tons of carbon dioxide emissions, to reduce sulfur dioxide emissions by 3.9 million tons. This will improve the power transformer in the international market competitiveness. \"
Transformer manufacturers, the concept of energy saving and environmental protection into product design, raw materials, manufacturing processes, providing customers with green product, is already the only way of product development.
Transformer energy saving and environmental protection, on the one hand, to reduce energy consumption and noise in the run, on the other hand should be to minimize the use of copper, iron, oil, insulation pieces of raw materials, to avoid excessive waste of non-renewable resources. In the design process to accurately calculate a variety of technical parameters of the transformer, preferably iron core and wire, to determine the appropriate proportion of copper and iron, the wires to produce a smaller vortex core and the structure of additional loss to try to control at a low level.
This can effectively reduce the use of copper and silicon steel, while reducing the load loss. Imported high quality selection of high permeability, low loss silicon steel manufacturing core can from raw materials to ensure that the transformer has a low no-load loss and low noise performance.
In addition, advanced technology is essential to manufacture energy saving and environmental protection transformer. Such as coil design, and widespread use of CTC manufacture of low voltage and high current coil, fully transposed in the common wire to reduce eddy current loss and circulating current loss of the coil; advanced sealing structure design, selection of high quality sealing components, strict sealing parts of metal parts precision machining, welding surface using double-sided welding process, strict tank inspection process to maximize control transformer during operation of the oil leaking oil spill.
