摘要
Abstract
Partial discharge problem is an important interference to the stability of power grid and threatens the safety of power equipments.By analyzing the modes and types of partial discharge of different gas insulated substation(GIS)equipment,the laws and characteristics of different discharge models are summarized.The causes and detection methods of partial discharge in GIS equipment are analyzed.By using the mode of wave frequency combination,the shortcomings of a single detection method can be effectively avoided,and the respective advantages of ultrasonic wave and ultra high frequency can be brought into play,so that the type and location of partial discharge can be accurately judged.Partial discharge live detection is conducted on the CIS equipment of a certain 500 kV substation.Based on the characteristics of partial discharge,the wave frequency combination is used to judge that it belongs to suspended discharge,and the discharge position is located in gas chamber A.The tank open-ing detection of power equipment is carried out,and the results prove the correctness and effectiveness of the proposed method,providing a treatment idea for the solution of related problems.关键词
