经济地使用现代大功率机车要求在整个速度范围内有效而可靠地实现轮轨间的牵引力和制动力,即要求尽可能地充分利用粘着限制。但在这种极限状况下运行很容易导至轮对的空转,检测出这种空转过程是多年来一切反空转装置最重要的功能。而目前,特别有价值的则是检测出将导至空转,从而使功率的有效发挥成为不可能的低速滑动过程。因此,问题不只在于当空转发生时检测出它的过程并及时地抑制它,更重要的还在于采取有效的措施防止它的发生。
The economical use of modern high-powered locomotives requires efficient and reliable tractive and braking forces between the wheel and rail throughout the speed range, requiring that adhesive constraints be utilized to the fullest possible extent. However, operation at this extreme condition can easily lead to the idling of the wheelset. Detection of this idling process is the most important function of all counter-rotating devices over the years. At the moment, it is particularly valuable to detect slow-slip processes that will lead to idling, making the efficient use of power impossible. Therefore, the problem lies not only in detecting the process of idling and suppressing it in time, but more importantly, taking effective measures to prevent it from happening.
