特高压(UHV) 试验 短路 标准化 断路器
2010/8/17
特高压(UHV)断路器试验本身就是一项挑战,当前,KEMA已开发了用于超高压和特高压开关设备大功率测试装置。鉴于特高压断路器一般至少由双断口灭弧室组成,需要做验证其正常电流(或故障电流)开断能力的局部试验,可以只针对断路器单断口(即断路器的1/2或1/4)来进行。例如,装有均压电容的瓷柱式断路器的情形就是这样。然而,为满足对金属封闭式开关设备的试验要求(见IEC 61633),在带电部件和外壳之间...
IEC 61850数字化保护动模测试系统设计与实现(Design and Implementation of Dynamic Simulation Testing System for Digital Protection Based on IEC 61850 )
IEC 61850 数字化保护 保护测试 物理模型 动态模拟
2010/8/17
IEC 61850标准的应用给变电站自动化系统带来了重大变革。在此类变电站中,保护装置可以直接从电子式互感器处获取所需的电流、电压数字量信息,并向智能开关控制器发送数字化跳闸命令。这种数字化保护与传统的微机型保护在硬件结构和信号处理方面都存在差异,传统的保护测试方法将不再适用。文章分析了基于IEC 61850的数字化保护装置的测试要求,提出通过对传统的物理模拟系统进行升级改造,建立符合要求的测试系...
