概述 FL80型控制板是六轴交直流电传动内燃机车上轮对空转保护系统中的一个部件。该轮对空转保护系统叫电流测量电抗器,缩写成CMR。当轮对空转或滑行时,它使牵引电动机电流失去平衡,通过励磁系统调整励磁,降低功率,起校正和保护作用。在司机室EC控制板上有一个试验按钮,用来检测CMR轮对空转保护系统的工作“比”。这在1974年1月后制造的带有CMR系统的所有机车上都有这一装置。
Overview FL80-type control panel is a component of the wheel idler protection system for six-axis AC-DC diesel locomotive. The wheel idling protection system called current measurement reactor, abbreviated as CMR. When the wheel idling or taxiing, it makes the traction motor current is out of balance, through the excitation system to adjust excitation, reduce power, play the role of correction and protection. There is a test button on the EC control panel of the cab to detect the “work” ratio of the CMR wheel to the idling protection system. This is available on all locomotives with CMR systems manufactured after January 1974.
