新型SF6电流互感器绝缘在线监测系统
The New Type Insulation On-line Monitoring System of SF6 Current Transformer
Based on ensuring no leakage and recycling of SF6,this paper presents a new type insulation on-line monitoring system for SF6 current transformer.According to the technology of infrared thermal sensor and electrochemical principle,this system can monitor continuously the purity of SF and detect the SO content of decomposition.Compared with other insulation monitoring devices of SF,it can not only evaluate directly the insulation status of transformers by monitoring the purity of SF6,but provide scientific basis for analysis of specific failure and potential internal fault.Therefore,the judge and predict for main insulation deterioration situation of current transformer can be realized.The result of experiment verifies the feasibility of the system.
