产品详细介绍
产品简介
在传统的输电线路工频参数测试中,采用三相自耦变和大容量隔离变压器提供测试电源,通过电力计量用的CT和PT作电信号变换,用指针式的高精度电压表、电流表、功率表测量各个电参数,计算得到输电线路工频参数测试结果。使整套试验设备体积大,重量大,需要吊车配合工作,十分不利于现场测量,而且由于测试电源为工频电源,极易与耦合的工频干扰信号混频,带来很大的测量误差,需要大幅度提高信噪比,这对电源的容量和体积又进一步提高。
NAYXL输电线路异频参数测试系统能够准确测量各种高压输电线线路(架空、电缆、架空电缆混合、同杆多回架设的工频参数(正序电容、正序阻抗、零序电容、零序阻抗、互感和耦合电容等),完全满足《110千伏及以上送变电基本建设工程启动验收规程》、DL/T559-94《220-500kV电网继电保护装置运行整定规程》、《GB50150-2006》的规定要求。
NAYXL输电线路异频参数测试系统采用一体化结构,内置变频电源模块,可变频调压输出电源。采用数字滤波技术,避开了工频电场对测试的干扰,从根本上解决了强电场干扰下准确测量的难题。
