Abstract According to the characteristics of 750kV transformer outlet device insulation structure, research of the technology was carried out. 2D and 3D engineering oriented simulated model of the key parts was established based on the Electro v6.2 and ElecNet7.0 software to analyse the safe margin. The main technology problems such as definition of the electronic finite model, 2D and 3D electronic analysis of the outlet device, and optimize design of the insulated structure was introduced. The electronic field calculation of the 750kV outlet device and the analysis of the safe margin were studied. Insulation defect was avoid by the optimize design of the electrode and insulation structure. The 750kV outlet device proposed in this paper was applied to a lot of engineering projects; the reliability of the homemade 750kV outlet device was validated by the experiment and performance of many products.

Key words： Transformer 750kV outlet device core technology homemade
