摘要
为实现变压器在线监测装置的有效性检验,应开发相应的状态仿真技术实现油中溶解气体、局部放电、铁心接地电流、绝缘油温度等状态量的有效模拟。笔者首先介绍了自制仿真平台的总体结构和工作机理,提出了油中溶解气体配置、绝缘油加热、油中放电信号产生、铁心接地电流产生的具体实现方式。其次在仿真平台上实现了变压器各种在线监测装置的安装固定,完成了变压器相关在线监测装置的可靠性检验。通过实验和检验结果证明,该仿真平台能有效模拟变压器状态量,完成变压器在线监测装置的有效检验。
To validate the effectiveness of different on-line monitoring devices for power transformers,a state emulation platform was constructed.The architecture and working principle of the platform are described,and the methods for realizing gas configuration,oil heating,partial discharge,and core grounding current are given.Then different on-line monitoring devices for transformer were fixed on the state emulation platform to test their reliability.Experiments demonstrate that this platform can emulate the state quantities of a transformer for validity check of the on-line monitoring devices.
