Abstract
Mine is mine hoist the large-scale production of essential equipment, the mine's production safety and played a very important role, has an important role in the national economy. Since hoist the production process is relatively high, so it's electric transmission and control devices has been the national electric transmission sector an important research areas. According to the design of upgrading the status of electrical control devices, selected the armature for circulation to the logic of non-reversible speed regulation system to study, the paper SCR to control the entire three-rectifier circuit of the main circuit system, using integrated circuit trigger. For a good dynamic and static quality, making full use of motor Guozainengli the fastest under the conditions of the entire system uses the dynamic current, double-loop speed of the armature for circulation to the logic of non-reversible speed regulation system.
