摘　　要：在变电站内,容性设备数量众多,其运行安全直接关系到整个变电站的稳定运行。容性设备传统检测手段是离线检修,停电后将设备拆除,然后进行绝缘性能检测,这种方式可以将一些潜在故障检测出来,但需要停电操作。而在线监测是利用传感器技术,在设备运行过程中对设备绝缘性能进行获取,不仅操作方便,而且可以实时对设备运行状态进行监测。对变电站容性设备介质损耗在线监测系统进行研究,给出系统架构,并对软硬件系统进行设计。In the substation,there are a large number of capacitive equipment,whose operation safety is directly related to the stable operation of the whole substation.The traditional detection method of capacitive equipment is offline maintenance.After cut of the power,the equipment is removed and insulation performance is tested.In this way,some potential faults can be detected,but power failure is needed.On line monitoring is the use of sensor technology to obtain the insulation performance of equipment in the process of equipment operation.It is not only convenient to operate,but also can monitor the operation status of equipment in real time.The on-line monitoring system of dielectric loss of transformer substation capacity equipment is studied,the system architecture is given,and the software and hardware system are designed.
