一、问题的提出: 提升绞车的动力制动具有很多优点,但是选择直流功率的计算问题比较复杂。现场技术人员在没有资料的情况下,往往选大,造成一定的浪费。 在这里对“动制”所需的直流功率上限进行探讨,以便使现场人员可以根据一些常用数据计算出较为准确的上限,作为选型参考。 一、对于“动制”的计算过程进行分析,能够发现,有大量的中间步骤和中间量可以省略。尤其是减少了查阅技术资料,甚至包括电机的试验报告。下面以星形绕组电机,串金属起动为例,对计算过程做尽可能的简化。
First, the question raised: to enhance the dynamic braking winch has many advantages, but the calculation of the choice of DC power is more complicated. In the absence of information on-site technical staff often choose large, resulting in some waste. Here the “dynamic” required DC power cap to explore, so that on-site personnel can calculate some of the more commonly used data to determine the upper limit, as a reference selection. First, analysis of the calculation process of the “system of motions” reveals that there are a large number of intermediate steps and intermediate quantities that can be omitted. In particular, reduced access to technical information, including motor test reports. Below the star winding motor, string metal starter, for example, to simplify the calculation process as much as possible.
