Abstract
The utility model provides an energy-saving loading-performance testing system for a frequency converter. The energy-saving loading-performance testing system for the frequency converter saves electric energy and is good in loading performance and comprehensive in testing. The energy-saving loading-performance testing system for the frequency converter includes a controller, a variable-frequency power source supplying power for the frequency converter to be tested, a motor working as a load of the frequency converter to be tested, a management module connected with the controller, a generator connected coaxially with the motor and a pulse feedback module connected with the generator. The pulse feedback module is also connected with the controller and the variable-frequency power source. The management module sends testing instructions to the controller. The controller sends electric signals to control the operation of the frequency converter to be tested and the pulse feedback module. The frequency converter to be tested controls the rotation of the motor and drives the generator to generate electric energy. The electric energy produced by the generator is sent to the pulse feedback module. The pulse feedback module converts the electric energy and then stores the converted electric energy into the variable-frequency power source. The pulse feedback module controls the generator to generate different impedance and inductive reactance. The controller receives the performance generation of the frequency converter to be tested and transmits to the management module.
