Product Overview
Key Features
Application Scope: It applies to the soft start and control of main circuit of wound-rotor or squirrel-cage three-phases AC asynchronous motor, with rated power of 50kW-500kW, rated voltage of 415/440V, and work frequency of 50Hz, which are widely used in metallurgy, building construction, petrochemical, chemical fertilizer, coal, pharmacy, sugar production and other industries.
Working Principal:
A special liquid resistor is serially connected to the rotor circuit of the controlled wound-rotor motor or the stator circuit of squirrel type motor. The main control circuit and the liquid resistor start circuit are arranged in the same cabinet. The liquid resistor gets to work when the starting process begins and its resistance gradually decreases during the preset time so that the motor can start smoothly and accelerate evenly at the minimal rated current and maximum torque. Then the switch is switched on (for wound-rotor asynchronous motor) or shifted (for squirrel cage asynchronous motor), which means that the liquid resistor is cut off and that the whole starting process is completed.
The device has such advantages as small start current, smooth start with no impact and no harmonic pollution. It is especially applicable to heavy-load starting.
