Terminology of motor soft starter
1 Scope
This standard defines the basic terminology of motor soft starter devices, soft starter terms, soft starter terms and other soft starter
Off the terms.
This standard is applicable to the production and application of AC motor soft starter.
2 terms and definitions
2.1
Soft start soft-start
By changing the motor terminal voltage, frequency or rotor circuit impedance, etc., so that the motor smooth acceleration to the specified speed of the process.
2.2
Soft stop soft-stop
By controlling the motor terminal voltage, frequency or rotor circuit impedance, etc., so that the motor from a certain speed smooth deceleration, until the stop
Running the process.
2.3
Soft starter soft-startdevice
A combination of switching devices and their control, measuring and regulating devices, as well as their interconnection with parts, accessories, protective shell, support
A device with a motor soft start function.
2.4
Step-down soft start soft-startbyvoltagereduction
The motor's soft start is achieved by reducing the terminal voltage of the motor.
2.5
Liquid resistance soft start soft-startbyliquidresistor
The soft start of the motor is achieved by smoothing the resistance value of the liquid resistance in series in the motor stator (or rotor) circuit.
2.6
Thermal resistance soft start soft-startbythermistor
The starting current of the motor causes the temperature of the liquid resistance in series with the negative temperature coefficient in the stator circuit to rise, the resistance value is gradually reduced,
So that the terminal voltage of the motor is gradually increased to realize the soft start of the motor.
2.7
Self-decompression soft start soft-startbyauto-transformervoltagereduction
Two or more taps are extracted from the autotransformer to reduce the terminal voltage at the time of starting the motor, thereby reducing the starting current.
The soft start of the motor.
Note. rewrite GB/T 2900.18-2008, defined 4.4.22.
2.8
Magnetically controlled soft start soft-startbyseriesreactor
By adjusting the excitation current of the reactor in series in the motor stator circuit, the saturation and reactance values of the reactor core are changed, thereby
Reduce the motor terminal voltage, to achieve the motor soft start.
