Small-capacity thyristor DC speed control system

  Product name

  Small-capacity thyristor DC speed control system training and assessment device

  Model (Type)

  BF-HYTS-01

  Feature

  The device adopts a general small-capacity thyristor DC speed regulation circuit, the main circuit is a single-phase bridge semi-control structure, the system adopts voltage negative feedback and current positive feedback control, and has a current cutoff negative feedback link and a series differential correction network. The device complies with the national "occupational standards" and the "training equipment industry standards" issued by the Ministry of Labor and Social Security of the People's Republic of China, and is suitable for various secondary vocational and technical schools. It is used in the teaching training of labor training and skill appraisal units and the intermediate/advanced practical assessment and skill appraisal of maintenance electricians.

  The device needs to have an extension interface, leakage protection and a special fault setting box. The self-provided unit can form a single closed-loop DC speed control system with static difference, and the fault point can be randomly set according to the requirements of teaching and assessment.
