SSCG250-3000/8000 250kW 796 Nm High Accuracy High Reliablity and Cost-effective Electric Dynamometer Test Bench System for Testing Engine Performance
Product description
SSCG250-3000/8000 electric dynamometer test bench system consists of an electric dynamometer, a set of torque and speed measuring sensors, a base and a flange connected to the power machinery. The system should be used together with DTC series variable frequency inverter system and Seelong's test and control system.
Its working principle is to invert the AC power from the electric dynamometer into DC power through the DTC inverter and then invert it into AC power for grid connection; DTC variable frequency inverter system adjusts the power grid current of the electric dynamometer to control the speed and torque of the prime mover. For example, when used together with the test and control system produced by Seelong, it can not only accurately measure and control the speed and torque of various rotating power machinery, but also can measure and control the temperature, pressure, flow, current, voltage, and other parameters.
SSCG250-3000/8000 electric dynamometer has two important features:
First, use the direct torque control technology to implement torque control on the AC dynamometer;
Second, when the AC dynamometer is in the power generation state, the electric energy is sent back to the grid.

SSCG250-3000/8000 electric dynamometers have the following advantages:
- It can be used as loading equipment and prime mover. It can drive and absorb power in both directions of rotation, so it is convenient to center (motor suspension) during installation
- Measurement accuracy: speed ± 1 R / min; torque ± 0.2% FS
- Loading stability: constant torque loading stability is better than 0.2%, constant speed driving is better than 0.1%
- Overload capacity: 120%
- Excellent loading performance: constant torque loading can be maintained from zero speed to rated speed, and constant power loading can be maintained above rated speed.
- Low moment of inertia and high overload capacity make the dynamometer have high dynamic response speed, the dynamic response speed is less than 5ms
System application
