Abstract
The invention relates to a system and a method for testing a magneto-rheological elevator traction transmission device. The system comprises a common DC bus mutual-feedback back-to-back test platform. The common DC bus mutual-feedback back-to-back test platform is formed by a frequency converter and tested magneto-rheological traction system, a frequency converter and load traction system, a torque speed measuring instrument and a control and monitoring system. The magneto-rheological elevator traction transmission device and a load traction machine are connected with the torque speed measuring instrument respectively through couplings. The torque and power of a traction host are lower than those of the load traction machine. Buses of two frequency converters of a load are connected through a controllable contactor. Since two sets of the traction machine and frequency converter systems share a DC bus and are coaxially connected, energy is fed back in the two systems, loss of energy is reduced, and energy utilization rate is greatly improved, so energy is saved and cost is reduced. Through the method, a low power level power supply can be used to complete a large power transmission system test, and the power supply does not need extension and reconstruction.
