摘要
干式空心限流电抗器普遍用于变电站、发电厂等场合以限制系统短路电流,由于干式空心电抗器运行时产生较大漏磁场,会引起周围金属件发热,严重时危及整个系统安全运行。为解决10 kV干式空心限流电抗器星臂和连接环发热问题,理论分析星臂和连接环发热产生的原因,通过优化星臂和连接环结构、加装导磁装置等措施达到降低温升的目的;同时利用有限元法进行仿真和厂内试验,验证了方案的可行性。
Dry type air core current limiting reactor is used widely in such places as substations and power plants in the purpose of limiting short circuit of the system.Due to the large leakage magnetic field of dry⁃type air core reactor during operation,it will cause the surrounding metal parts to heat and,in case of serious condition,endanger safe operation of the whole system.In order to solve the heating problem of the star arm and the connection ring of 10 kV dry air core current limiting reactor,the causes of the heating of them are analyzed theoretically,and the purpose of reducing the temperature rise is achieved by optimizing the structure of the star arm and the connecting ring and adding magnetic devices and other measures.At the same time,the feasibility of the scheme is verified by simulation and factory test through the finite element method.
