66KV Line Transformer Unit Composite Type Combined Electrical Appliance (T-GIS) Design And Application

With the rapid development of power grids, substation miniaturization, intelligence is the inevitable trend, according to the State Grid Corporation of China power grid construction " Two type and Industrialization " requirement, combined with the domestic network rapid development actual need, limited company of Liaoning province power forward substation primary equipment of highly integrated, meet66kV transformer substation construction needs, at the same time to adapt to the requirements of the development of intelligent power grid. Based on this, this article on the basis of a equipment integrated design research and development train of thought, put forward and organization development66kV line transformer composite type combined electrical appliance (T-GIS).T-GIS combined electrical appliance take level or the three-dimensional arrangement, the transformer, combined electrical equipment two kinds of functional devices into one, the structure becomes very compact, particularly applicable to the load end of line and transformer substation in the form of.This paper from the entire T-GIS combined electrical research and design, product testing and other aspects of the new equipment, designed two kinds of T-GIS layout, and design to meet the requirements of the transformer and the high voltage combined electrical equipment (HGIS). The structure of model refinement, design implementation of three-dimensional type T-GIS device, and the transformer substation intelligent structure matching.After completing the T-GIS device design, organization of its type test and the Factory test, the test results to achieve the expected results, the product is well adapted to site requirements, achieving a height of equipment integration needs.
