The thermal resistance starting device is a new type of soft starting device for high-voltage and high-power motors. Its main technical feature is that the resistor is made of resistance materials with negative temperature coefficients and other components. This device is connected in series in the stator circuit of the motor. When the motor starts, the temperature of the resistor body increases through the current and the resistance value decreases. The voltage at the stator terminal of the motor gradually increases and the starting torque gradually increases, thereby achieving safe and smooth starting of the motor. The starting resistance value of the thermal resistance device can be easily prepared according to the parameters of the motor and the starting torque requirements to obtain the ideal starting parameters, that is, the ideal starting current, starting time and starting torque.
Performance characteristics
Constant current, soft start (the starting current is .-. times the rated current of the motor, which reduces the heat generated by the motor during starting and effectively extends the service life of the motor)
Ensures a successful start without being affected by grid voltage fluctuations and loads
Smooth starting, no impact on mechanical equipment
Little impact on the power grid, the voltage drop of the power grid during starting time is within %
Simple structure and easy maintenance.
Scope of application
Depending on the capacity of the optional high-voltage thermal resistor, this starter can be suitable for step-down starting of motors with rated voltages of 100 to 1000 kW or power ranges from 100 to 1000 kW or even larger capacities.
Usage environment
The upper limit of ambient air temperature does not exceed ℃ and the lower limit is not lower than ℃
The relative temperature does not exceed %
The altitude does not exceed meters (negotiable under special circumstances)
Should Installed in a situation without significant shaking and shock vibration and the vertical inclination does not exceed excessive
In a medium with no explosive hazard and without conductive dust or various corrosive gases.
