直流供电系统的电压、电流和温度测量

数十年来，Knick 致力于提供优质的电气隔离变送器，用于可靠、精确测量直流设备中的电压和电流。公司历经风雨，现已发展成为该领域的全球市场领导者。因此，当直流设备供应商和运营商遇到特殊技术挑战时，例如需要磨损监测解决方案实现预防性维护，Knick 总能挺身而出，为客户排忧解难。

为何选择 Knick?
变电站中的保护装置必须测量电流和电压，以便执行短路检测算法。这就需要能够快速精确测量、同时又能承受高负荷的高压变送器。其必须能承受 750 至 3000 V 之间的直流电压，包括瞬时的过电压，例如在制动列车的能量回收过程中。在这些高压应用中，对人员和设备的保护至关重要。因此，Knick 设备所具有的强电气隔离特性，是客户选择变送器的重点考虑因素。
