基于不同放电模型的变压器局部放电光学特性研究
Research on the optical properties of partial discharge in transformers based on different discharge models
摘要
Abstract
In this paper , the different types of discharge in transformer were simulated based on the establishment of the real transformer fault model .Meanwhile , the optical partial discharge detection system was established based on optical sensors which was capture partial discharge accompanied by optical effects .In this research , the surface dis-charge and suspended discharge defect model were pressurized to generate partial discharge signals .The results showed that the partial discharge optical signals can effectively respond the production and development process of par -tial discharge in transformer .It is able to assess discharge level as well .When the discharge phenomenon stabilized , the phase of surface discharge was mainly between 60°~150°and 240°~330°, the phase of suspended discharge was mainly between 260°~320°.According to the phase characteristic of partial discharge signals , the creeping dis-charge and suspended discharge phenomenon of transformer can be distinguished .It laid the foundation for the appli-cation of detection technology of optical partial discharge in transformer .关键词
