以电气隔离方式远程传输测量数据

风电机组的性能数据是可靠评估其效率的核心依据。为了对数据进行精准分类，需将其与远距离测量塔的测量值进行比较——远距离测量塔作为独立参照基准。风电机组性能验证周期漫长，对所采用的测量技术来说，这无疑是项极具挑战性的任务，因此，卓越的坚固耐用性和长期稳定性不可或缺。

技术难度高：在风电机组和测量塔之间传输数据

成功采集到的测量数据通常需要穿越数百米距离，在风电机组与测量塔之间传输。远距离传输信号面临多重挑战，比如地电位差异、瞬态过电压等。这些会给测量设备造成干扰，甚至导致损坏，进而影响风电机组的评估准确性。为此，需要采用故障率极低的隔离放大器，确保信号源与评估单元之间实现电气隔离。此外，该系统还需将数据记录器、SCADA 等不同系统的单/双极性信号，统一转换为标准信号以供后续处理。

Why Knick ?
P27000 具有 480 个已校准、可切换的测量范围，以及适用于所有常用电源电压的宽范围电源，堪称隔离放大器中的“万用表”。此系列产品增益误差 < 0.08 %，T₉₀ 响应时间仅 70 μs（截止频率设为 10 kHz 时），为实现近乎完美的无延迟信号传输提供有力保障。此外，隔离放大器采用可插拔螺钉端子，安装简单省时，结构紧凑。

坚固耐用、长期稳定、应用广泛：P27000 系列

P27000 系列通用隔离放大器是监测性能数据的理想解决方案。现场数据显示，该系列产品平均故障间隔 (MTBF) 长达 3,941年，可用性极高，能有效规避长期测量中因中断而导致的巨大成本风险。

P27000 的增益误差 < 0.08 %，温度系数 < 0.005 %/K（基于测量范围终值），即使环境温度出现剧烈波动，也可持续提供精确测量结果。
