整流子试验台是204直流牵引电动机整流子超速试验用的关键设备。过去,试验用的直流电动机由15瓩电动机一发电机组供电。这不仅经济上不合理,而且整个试验过程由人工操作。现在,改用可控硅控制代替原来的电动机一发电机组,不但简化了设备,消除了噪音,而且实现了自动控温和操作。整流子试验台的工作对象是10.5瓩他激直流电动机和15瓩电烘炉。在试验过程中,电炉 Commutator test rig is 204 key DC motor traction motor commutator speeding test with the key equipment. In the past, the experimental DC motor was powered by a 15 瓩 motor-generator set. This is not only economically unreasonable, but also the entire testing process is manually operated. Now, the use of SCR instead of the original motor-generator set, not only simplifies the equipment, eliminating noise, but also to achieve automatic temperature control and operation. Commutator test stand is the target of 10.5 瓩 he excited DC motor and 15 瓩 electric oven. During the test, the electric furnace
