介质损耗在线监测设备的研制

对电容型设备进行定期检修是变电站的重要任务，但传统的方法存在试验周期长、强度大、成本高等缺点，也不适应现代信息化管理的发展，目前在线监测是一个研究热点。本文描述了实际介质损耗在线监测设备研制的过程，实践比较了数字化介损测量的各种软硬件方法。在原理上采取综合相对比较法，系统设计上采取网络化统一监控和现场监控相结合的方案。现场运行表明，该方案能有效克服干扰，提高在线监测的稳定度。

Development of Usual Online Monitoring of Dielectric Loss Factor Devices

It is an important assignment of transformer substation,traditional periodic examination and repair on capacitive devices has the disadvantages of long experimental period,intensive exhaustion,high price and does not follow the modern information management trends,which makes online surveillance become a hot interest of research field.This paper describes our work on the development of usual online monitoring the dielectric loss factor devices,including the practical compare among various software and hardware measures,adoption of relative compare method and some innovation on system design to overcome disturbance and to increase accuracy and to improve efficiency.
